EXECUTIVE SUMMARY
The distribution of submerged aquatic vegetation (SAV), principally rooted vascular macrophytes
in the Chesapeake Bay, its tributaries, and the coastal bays of the Delmarva Peninsula, was mapped
from 1,728 black and white aerial photographs. These were taken between May and October 1997,
at a scale of 1:24,000, encompassing 141 flight lines covering 1,808 miles of shoreline.
In 1997, 28,032 hectares of SAV were mapped in Chesapeake Bay and its tributaries (Figures 1 and
2a). This was a 9% increase (2,336 hectares) from 1996 levels and represents a second consecutive
year of SAV increase following two consecutive years (1994 and 1995) of declining SAV abundance
(Figure 2a). The abundance of SAV in 1997 represented 61% of the Tier I goal (46,022 hectares)
set by the Chesapeake Executive Council in Directive 93-3 (Figure 2a).
SAV increased in all three geographic zones delineated for Chesapeake Bay. In the Upper Bay zone
(from the Susquehanna River, south to the Chester and Magothy rivers - Figure 1), SAV increased
to 4,439 hectares, representing 61% of the Tier I goal, an increase of 27% from 1996 (Figure 2b).
In the Middle Bay zone (from the Bay Bridge, south to the Rappahannock River and Pocomoke
Sound, and including the Potomac River - Figure 1), SAV increased to 14,209 hectares, representing
57% of the Tier I goal, an increase of 8% from 1996 (Figure 2b). In the Lower Bay zone (from the
Rappahannock River and Pocomoke Sound areas, south to the mouth of the Bay - Figure 1), SAV
increased to 9,383 hectares, representing 68% of the Tier I goal, an increase of 3% from 1996 (Figure
2b).
SAV increased in 33 of the 78 Chesapeake Bay Program segments (Figures 3,4, and 5). Twenty-one
of the segments had increases of 20% or greater from 1996. In the Upper Bay zone (Figure 3), these
increases occurred in: the Upper Chesapeake Bay segment (CB2OH), 83 hectares - 299%; the Elk
River (ELKOH), 24 hectares - 54%; the Bohemia River (BOHOH), 3 hectares - 20%; the
Gunpowder River (GUNOH), 266 hectares - 71 %; the Middle River (MIDOH), 86 hectares - 277%;
the Chester River (CHSMH), 113 hectares - 36%; and the Magothy River (MAGMH), 16 hectares -
44%. Also notable, in CB1TF, which includes the Susquehanna River/Flats area, SAV increased 343
hectares or 16%. In the Middle Bay zone (Figure 4), increases of 20% or more occurred in the
following segments: the South River (SOUMH), 8 hectares - 88%; Middle Central Chesapeake Bay
(CB4MH), 20 hectares - 100%; the Lower Patuxent River (PAXMH), 1 hectare - 100%; the Lower
Potomac River (POTMH), 264 hectares - 66%; Piscataway Creek (PISTF), a tributary of the
Potomac River, 72 hectares - 142%; Eastern Bay (EASMH), 360 hectares - 24%; the Lower
Choptank River (CHOMH2), 2 hectares -100%; the Little Choptank River (LCHMH), 185 hectares -
54%; the HongaRiver (HNGMH), 268 hectares - 43%; the Manokin River (MANMH), 48 hectares -
602%; and the Big Annemessex River (BIGMH), 55 hectares - 63%. Notable increases also occurred
in the Mouth of the Choptank River (CHOMH1), 449 hectares - 19%, and in the Middle Potomac
River (POTOH), the oligohaline portion, 170 hectares -16%. In the Lower Bay zone (Figure 5), the
increases occurred in: the Piankatank River (PIAMH), 33 hectares - 23%; the Lower James River
(JMSMH), 1 hectare - 100%; and the Mouth of the James River (JMSPH), 57 hectares - 303%.

Notable increases also occurred in the Eastern Lower Chesapeake Bay (CB7PH), 106 hectares -3%,
and in Mobjack Bay (MOBPH), 140 hectares - 3%.
SAV decreased in 12 of the 78 bay and tributary segments. Three of those 12 segments had
decreases of 20% or more from 1996, all occurring in the Lower Bay zone (Figure 5): Lower
Rappahannock River (RPPMH), 11 hectares - minus 43%; Corrotoman River (CRRMH), 7 hectares -
minus 31%; and Lynnhaven Bay (LYNPH), 14 hectares - minus 47%. In the Middle Bay zone,
although the Tangier Sound segment (TANMH) did not have a decrease of 20%, the decline of SAV
there was notable for two reasons: SAV had declined for the fifth straight year in this segment which
contained a significant portion of the entire SAV in Chesapeake Bay (14% of the 1997 Bay total);
and the magnitude of SAV decline from 1996 to 1997 (636 hectares - 15% decrease) was much
greater than any of the increases in any one segment. An additional notable decrease also occurred
in the Lower Pocomoke River (POCMH), 122 hectares - 19% decrease.
SAV was not present or was not sufficiently abundant to be mapped in 28 of the 78 Chesapeake
Bay Program segments.
SAV increased in the Delmarva Peninsula coastal bays (Chincoteague, Sinepuxerit, Isle of Wight,
Assawoman, andMagothy bays) to 5,598 hectares, an increase of 1,042 hectares, or 23%, from 1996.
Total hectares for each of the bays were: Chincoteague Bay - 4,917 hectares, compared to 3,988
hectares in 1996; Sinepuxent Bay - 421 hectares, compared to 344 hectares in 1996; Isle of Wight
Bay - 80 hectares, compared to 46 hectares in 1996; Assawoman Bay - 180 hectares, compared to
178 hectares in 1996; and Magothy Bay - no SAV was mapped, but SAV was present in small
patches which had been planted in 1996. Significant damage to SAV beds was noted here in 1997,
which was caused by commercial clam dredging activities (principally in Chincoteague and
Sinepuxent bays). These areas were protected in 1998 by state legislation passed for the Maryland
portions and by a SAV sanctuary established in Virginia's portion of Chincoteague Bay.

SAV SPECIES
The term "submerged aquatic vegetation" (SAV) for the purpose of this report encompasses twenty-
one taxafrom ten vascular macrophyte families and three taxa from one freshwater macrophytic algal
family, the Characeae. The term "SAV" in this report excludes all other algae, both benthic and
planktonic, which occur in Chesapeake Bay, its tributaries, and the Delmarva coastal bays (Appendix
A). Although these other algae do constitute a portion of the SAV biomass in Chesapeake Bay, its
tributaries, and the Delmarva coastal bays (Humm, 1979), this survey did not attempt to identify,
delineate, or discuss the algal component of the vegetation nor its relative importance in the flora,
except for the Characeae. This is the case, for example, with many benthic marine algae species,
including many macrophytes, which can sometimes co-occur in the same beds with submersed
vascular plants, even as epiphytes on submersed vascular plants, and which cannot be differentiated
from them in the aerial photography used by this survey.
Ten species of submerged aquatic vegetation are commonly found in the Chesapeake Bay and its
tributaries. Zostera marina (eelgrass) is dominant in the lower reaches of the bay. Myriophyllum
spicatum (Eurasian watermilfoil), Potamogeton pectinatus (sago pondweed), Potamogeton
perfoliatus (redhead grass), Zannichelliapalustris (hornedpondweed), Vallisneria americana (wild
celery), Elodea canadensis (common elodea), Ceratophyllum demersum (coontail), and Najas
guadalupensis (southern naiad) are less tolerant of high salinities and are found in the middle and
upper reaches of the bay (Stevenson and Confer, 1978; Orth et ai, 1979; Orth and Moore, 1981,
1983). Ruppia maritima (widgeon grass) is tolerant of a wide range of salinities and is found from
the bay mouth to the Susquehanna Flats. Approximately 14 other species are only occasionally
found. When present, these species occur primarily in the middle and upper reaches of the bay and
the tidal rivers (Appendix A). Hydrilla verticillata (hydrilla), a recently introduced species, continues
to dominate SAV beds in the tidal freshwater reaches of the Potomac River, although many of the
large beds of hydrilla have recently declined. It was also reported again in 1997, in the Susquehanna
River and Flats, where its growth was not as widespread as in the Potomac River (Kollar, pers.
comm.), as well as the Patuxent river tidal freshwater areas.
Zostera marina and R. maritima are the species reported from the Delmarva coastal bays.

SAV
METHODS
INTRODUCTION
Black-and-white aerial photography at a scale of 1:24,000 was the principal source of information
used to assess distribution and abundance of SAV in Chesapeake Bay, its tributaries, and five
Delmarva coastal bays in 1997. The Delmarva coastal bays mapped in 1997 includes: Chincoteague,
Assawoman, Sinepuxent, Isle of Wight, and Magothy bays, but exclude Fishermans Island. There
were 141 flight lines which yielded 1,728 photographs which were carefully examined to identify all
SAV beds visible on the photography. Outlines of SAV beds were subsequently drawn onto USGS
7.5 minute quadrangles and then digitized, providing a GIS digital database for analysis of bed areas
and locations. Ground survey information collected in 1997 was tabulated, then drawn onto the same
7.5 minute quadrangles, and, finally, entered into the VIMS SAV GIS digital database.
AERIAL PHOTOGRAPHY
The 1997 aerial photography was obtained by Air Photographies (Martinsburg, West Virginia) using
a Wild RC-20 camera, with a 153 mm (6 inch) focal length Aviogon lens and Agfa. Pan 200 film,
mounted in the bottom fuselage of a Piper Aztec, a twin engine reconnaissance aircraft. Photography
was acquired from an altitude of approximately 12,000 feet, yielding 1:24,000 scale photographies.
The 141 flight lines, which cover l,808milesof shoreline, were numbered and included land features
necessary to establish control points for accurate mapping (Figure 6). Flight lines to obtain the
photography were predetermined by Air Photographies to include all areas known to have SAV, as
well as most areas which could potentially have SAV in the middle and upper zones [i.e., all areas
where water depths were less than 2 meters at mean low water (MLW)]. In the lower zone, sections
of the upper Rappahannock and upper York rivers, and most of the James River, were not
photographed for analysis because of the continued absence of SAV in these areas as evidenced by
ground truth.
Flight lines were prioritized by sections, and flights were timed to occur during the peak growing
season of species known to occur in the sections. In addition, specific areas with significant SAV
coverage were given priority. Dates of photography are noted on each quadrangle in Appendix B.
Guidelines for acquisition of aerial photography (Table 1) address tidal stage, plant growth, sun
elevation, water and atmospheric transparency, turbidity, wind, sensor operation, and plotting.
Adherence to the guidelines assured acquisition of photography under nearly optimal conditions for
detection of SAV, thus insuring accurate photo interpretation. Deviation from any of these guidelines
required prior approval by VIMS staff. Quality assurance and calibration procedures were
consistently followed. The altimeter was calibrated annually by the Federal Aviation Administration.

TABLE 1
Guidelines Followed During Acquisition of Aerial Photographs.
1. Tidal Stage - Photography was acquired at low tide, +/- 0-1.5 ft., as
predicted by the National Ocean Survey tables.
2. Plant Growth - Imagery was acquired when growth stages ensured maximum
delineation of SAV, and when phenologic stage overlap was greatest.
3. Sun Angle - Photography was acquired when surface reflection from sun glint
did not cover more than 30 percent of frame. Sun angle was generally
between 20° and 40° to minimize water surface glitter. At least 60 percent
line overlap and 20 percent side lap were used to minimize image degradation
due to sun glint.
4. Turbidity - Photography was acquired when clarity of water ensured
complete delineation of grass beds. This was visually determined from the
airplane to insure that SAV could be seen by the observer.
5. Wind - Photography was acquired during periods of no or low wind.
Offshore winds were preferred to onshore winds when wind conditions could
not be avoided.
6. Atmospherics - Photography was acquired during periods of no or low haze
and/or clouds below aircraft. There could be no more than scattered or thin
broken clouds, or thin overcast above aircraft, to ensure maximum SAV
contrast to bottom.
7. Sensor Operation - Photography was acquired in the vertical mode with less
than 5 degrees tilt. Scale/altitude/film/focal length combination permitted
resolution and identification of one square meter area of SAV (at the surface).
8. Plotting - Each flight line included sufficient identifiable land area to assure
accurate plotting of grass beds.
-------
1997
Camera settings were selected by automatic exposure control. Sun angle was measured with a sensor
on the plane. Flight lines were plotted on 1:250,000 scale maps to allow for overlap of photography.
To minimize image degradation due to sun glint, the camera was equipped with a computer controlled
intervalometer which established 60% line overlap and 20% sidelap. An automatic bubble level held
the camera to within one degree tilt. The scale/altitude/film/focal length combination was coordinated
so that S AV patches of one square meter could be resolved. Ground-level wind speed was monitored
hourly. Under normal operating conditions, flights were usually conducted under wind speeds less
than 10 mph. Above this speed, wind-generated waves stir bottom sediments which can easily
obscure SAV beds in less than one hour. The pilot used experiential knowledge to determine what
acceptable level of turbidity would allow complete delineation of SAV beds. During optimum flight
conditions the pilot was able to distinguish bottom features such as SAV or algae at low tide.
Excessively turbid conditions precluded photography. Determination of optimum cloud cover level
was based on pilot experience. Records of this parameter were kept in a flight notebook. Every
attempt was made to acquire photographs when there was no cloud cover below 12,000 feet. Cloud
cover did not exceed 5% of the area covered by the camera frame. A thin haze layer above 12,000
feet was generally acceptable. Experience with the Chesapeake Bay has shown that optimal
atmospheric conditions generally occur two to three days following passage of a cold front, when
winds have shifted from north-northwest to south and have moderated to less than 10 mph. Within
the guidelines for prioritizing and executing the photography, the flights were planned to coincide
with these atmospheric conditions where possible. All film was processed by Air Photographies. A
9 inch x 9 inch, black-and-white contact print was produced for each exposed frame. Each
photograph was labeled with the date of acquisition as well as the flight line number. Film and
photographs were stored under appropriate environmental conditions to prevent degradation.
MAPPING PROCESS
For this analysis, USGS 7.5 minute quadrangle maps were utilized for mapping SAV beds from aerial
photography, for digitizing the SAV beds, for mapping ground-truth data, and for compiling SAV
bed area measurements. Figure 7 gives locations of 229 quadrangles in the study area which includes
all regions with potential for SAV growth. Most quadrangles are sequentially numbered for efficient
access to data. The name corresponding to each quadrangle in Figure 7 is listed in Table 2.
Identification and delineation of SAV beds by photo interpretation utilized all available information
including: knowledge of aquatic grass signatures on film, distribution of SAV in 1997 from aerial
photography, 1997 ground-truth information, and aerial site surveys. USGS 7.5 minute quadrangle
maps (1:24,000 scale) printed by the Mid-Continent Mapping Center of the National Cartographic
Information Center on stable, transparent mylar were used as base maps from which to make copies.
Distortion-free, identical copies of these base maps were made at the same scale on stable, transparent
mylar, using a contact print process. SAV beds from 1997 aerial photographs were mapped onto
these mylar copies of USGS 7.5 minute quadrangles. Delineation of each SAV bed was facilitated
by superimposing the photographic print with the appropriate mylar quadrangle on a light table. SAV
bed boundaries were then traced directly onto the mylar quadrangle with a pencil. Where minor scale

differences were evident between a photograph and a quadrangle, or where significant shoreline
erosion or accretion had occurred since USGS publication of a map, either a best fit was obtained or
shoreline changes were noted on the quadrangle. All photo interpretation of 1997 aerial photography
for SAV beds was done by one scientist who also photo interpreted the 1987 to 1996 aerial
photographs.
SAV beds were identified and ground truthed with the collaboration of Stan Kollar for the head of
the Bay region, including Susquehanna Flats and the Elk, Bohemia, and Sassafras rivers, and with
Virginia Carter, Nancy Rybicki, and Henry Ruhl for the Potomac River. Delineation of the large bed
on the Havre de Grace map was facilitated by both aerial photography and ground observations.
In addition to delineating SAV bed boundaries, an estimate of SAV density within each bed was made
by visually comparing each bed to an enlarged Crown Density Scale (Figure 8) similar to those
developed for estimating crown cover of forest trees from aerial photography (Paine, 1981). Bed
density was categorized into one of four classes based on a subjective comparison with the density
scale. These were: 1, very sparse (<10% coverage); 2, sparse (10-40%); 3, moderate (40-70%); or
4, dense (70-100%). Either the entire bed or subsections within the bed were assigned abed density
number (1 to 4) corresponding to the above density classes. Some beds were subsectioned to
delineate variations of SAV density. Additionally, each distinct SAV bed or bed subsection was
assigned an identifying one or two letter designation unique to its map. Subsections were further
identified as contiguous beds by addition of one or two letters unique to that sequence. Contiguous
bed identifications aided tracking and analysis of single natural bed units subsectioned due to
variations of SAV density. Coupled with the appropriate SAV map number and year of photography,
these letter designations uniquely identify each SAV bed in the database.
SAV PERIMETER DIGITIZATION AND QUALITY ASSURANCE PROCEDURES
Perimeters of all SAV beds mapped from aerial photography onto mylar copies were digitized in
ARC/INFO, using an Altek Model 41 tablet with a resolution of .001 inches (.00254 cm) and an

accuracy of .005 inches (.0127 cm). Beds for each quadrangle were digitized in a primary
ARC/INFO coverage and, as a quality assurance check, in a secondary ARC/INFO coverage. These
coverages were overlaid digitally. If the area of a bed that differed between the two copies was more
than 1 hectare and made up more than 2% of the bed, or was more than 0.1 hectare_and made up
more than 10% of the bed, the bed was flagged for additional review. The primary coverage was then
plotted at an exact scale of 1:24,000 on translucent plotter paper and overlaid on the original mylar
for visual checking of all beds, with additional emphasis on beds flagged by the overlay step. In
instances where the digitized SAV bed boundaries did not correspond to within 0.5 mm of the
original, the bed was redigitized. The bed-by-bed comparison was useful in identifying registration
errors or instances where SAV beds were incorrectly labeled, thus eliminating coding errors.
After all quadrangles were digitized, the resulting digital data was combined to form a single data set
for the entire Bay. The quadrangle borders were then scanned (edgematched) to ensure that the SAV
polygons were consistent. Inconsistencies were resolved by checking the mylar maps and re-
interpreting the photography if necessary. The resulting digital data was added to the VIMS SAV
GIS Database containing all previous years' data.
Maximum accuracy was maintained by exclusively using mylar quadrangles, which do not change
scale as a result of changes in air temperature and humidity in the digitizer room.
Standard operating procedures (SOPs) were developed to facilitate orderly and efficient processing
of 1997 SAV maps and SAV computer files produced from them, and to comply with the need for
consistency, quality assurance, and quality control. SOPs included: a detailed procedure for
digitization of SAV maps; a digitizer log in which all operations were recorded and dated, used to
guide and verify operations; and a flow chart used to track progress of all operations.
CALCULATION OF 1997 SAV AREAS
SAV coverages in Universal Transverse Mercator (UTM), ARC/INFO, Zone 18 format were used
to calculate area in square meters for all SAV beds. These areas are reported as USGS 7.5 minute
quadrangle, Chesapeake Bay Program segment, and zone totals in tables in the Results section.
Segment and zone totals were calculated using an overlay operation of segment and zone regions
on the SAV beds in ARC/INFO.
ORGANIZATIONAL PROCEDURES FOR ANALYSIS AND DISCUSSION
SAV distribution data are presented and discussed based on new segmentation and zonation schemes
from those used in SAV distribution and abundance reports prior to 1997. The segmentation scheme

as established by Orth and Moore (1982) and modified by Orth et al., (1989) was adapted to the new
segmentation scheme. It was followed as closely as possible but, necessarily, had to be modified to
accommodate the new segment boundaries (Figure 9). Data are presented for 1978-1997, where
available, using the new Chesapeake Bay Program segmentation scheme.
The Upper Bay zone includes the Susquehanna River and extends to the Chesapeake Bay Bridge; the
Middle Bay zone extends to the southern boundaries of CB5MH, TANMH, and POCMH; the Lower
Bay zone extends to the mouth of Chesapeake Bay and includes the James River (Figure 9). The
salinity within each zone roughly coincides with the major salinity zones of estuaries: polyhaline
(18-25 7oo), Lower zone; mesohaline (5-18 7oo), Middle zone; oligohaline (0.5-5 7oo), Upper zone.
Although the major rivers and smaller tributaries of Chesapeake Bay have their own salinity regimes,
the distribution of SAV in each river is discussed within the zone where it connects to the Bay. SAV
distribution in the Delmarva coastal bays is presented and discussed separately from Chesapeake Bay.
The Delmarva coastal bays zone, for the purpose of discussion in the figures and tables, includes five
barrier island bays: Chincoteague, Assawoman, Sinepuxent, Isle of Wight and Magothy bays, but
excludes Fishermans Island.

SAV
GROUND SURVEYS AND OTHER DATABASES
Ground surveys were accomplished by cooperative efforts from a number of agencies and individuals.
Although not all areas of Chesapeake Bay and the Delmarva coastal bays were ground surveyed, the
data did provide valuable supplemental information. The ground surveys confirmed the existence of
some SAV beds mapped from the 1997 aerial photography, as well as SAV beds not visible from the
photography because they were too small at 1:24,000 scale. The surveys also provided species data
for many of the SAV beds. Ground survey information supplied to VIMS researchers was included
on the SAV distribution and abundance digital maps reproduced in Appendix B and included in the
VIMS SAV GIS Database. Each survey was designated by a unique symbol to identify the different
methods of sampling. In most cases the symbols on the SAV maps (Appendix B) were enlarged and
offset from the actual sampling point to avoid confusion with the mapped SAV bed. Where species
information was available, it was included on the map. Because of space limitations on the maps
reproduced in Appendix B, occasionally one or more survey points were combined where the
information was duplicated. All ground survey data supplied to VIMS were tabulated in Appendix
D.
In Maryland, ground survey data were obtained in 1997 by VMS; Stan Kollar of Harford Community
College; Virginia Carter, Nancy Rybicki, and Henry Ruhl of the USGS National Center; Peter
Bergstrom of the USFWS; Kent Mountford and Marcia Olson of the USEPA; Mike Naylor of
Maryland Department of Natural Resources (MD-DNR); Bob Stankelis of Chesapeake Bay
Laboratories (CBL) of the University of Maryland; U. S. Army Environmental Center/Army Research
Laboratory (USAEC/ARL) (Aberdeen Proving Ground); Dan Stotts of Patuxent Wildlife Research
Center (PWRC); Patuxent River Park staff; the National Park Service; the U.S. Army Corps of
Engineers, Baltimore District (ACOE); and by the Citizens' volunteer survey (The SAV Hunt). The
USGS National Center and USFWS provided ground survey data for the Potomac River. Peter
Bergstrom provided ground survey data for the Magothy, Severn, Chester, and Choptank rivers.
Kent Mountford and Marcia Olson provided species data for Herring Bay. Dan Stotts provided
extensive ground data survey for the Chester, Miles, and Choptank rivers, and for Eastern Bay.
Patuxent River ground survey data were obtained by the MD-DNR, and Maryland-National Capital
Parks and Planning Commission staff at Patuxent River Park. The U.S. Army Environmental
Center/Army Research Laboratory staff provided ground truthing for Aberdeen Proving Ground area.
The Army Corp of engineers provided species information for Shallow Creek. VIMS, the National
Park Service, and the Ocean Pines Yacht Club (SAV Hunt) provided ground truthing for the coastal
bays.
The SAV Hunt (Citizens' survey), under the guidance of the USFWS and assisted by the Chesapeake
Bay Foundation, included ground truthing by citizens; students and educators at Gibson Island
Country School, Millersville University, and Southern Middle School; and members of the Sherwood
Forest Naturalist Program, Friends of Mattawoman Creek, and the National Aquarium in Baltimore.

-------
1997
SAV Hunt (Citizens' survey) volunteers identified SAV locations and SAV species throughout
Chesapeake Bay and the Delmarva coastal bays. Volunteers recruited through press releases,
newsletters, and personal letters, were provided with a SAV identification guide, reduced 1996 SAV
maps to aid in the location of SAV beds, and data sheets for reporting visits to numerous sites around
the bays. USFWS staff mapped the data on copies of 1996 SAV distribution maps (USGS 7.5 minute
quadrangles with 1996 SAV beds). These maps were supplied to VIMS SAV researchers and
transferred to the 1997 SAV distribution maps reproduced in Appendix B. Data from the Patuxent
River Park staff, and the Citizens' surveys (The SAV Hunt) were compiled and tabulated by USFWS.
This table became the basis of the much expanded table published in Appendix D.
One 1997 SAV research project being conducted on the Susquehanna Flats by Stan Kollar of Harford
Community College, Maryland, also provided data in the form of species presence by estimated
percent cover, although these percentages are not reported here.
For those areas in Virginia waters where aerial photographic evidence of SAV beds was inconclusive,
photo verification was accomplished by ground-truth surveys. Observations were principally made
from small boats and by divers snorkeling over areas indicated from the photographs. In the York,
and James rivers, where VIMS researchers transplanted SAV (principally eelgrass), transplant sites
were also examined carefully by divers for any extant SAV. VIMS scientists also surveyed a number
of sites in the Chesapeake Bay as part of an intensive quantitative SAV-blue crab study (VIMS,
unpublished data). Data for Virginia waters were also collected by the Citizens' volunteer survey
(The SAV Hunt) and compiled by the USFWS. In addition, a great deal of ground survey
information could be extrapolated from earlier studies (Orth et al., 1979; Orth and Moore, 1982).
SAV beds in the lower Bay contained primarily one or two species and most areas underwent wide
fluctuations in distribution and abundance since the first baywide survey in 1978.
Ground survey data from all sources reported here are presented in Appendix D.

RESULTS
DATA PRESENTATION
Chesapeake Bay 1997 SAV distribution data and ground-truth data are presented and discussed based
on the 1997 Chesapeake Bay Program (CBP) segmentation scheme, as well as on Upper, Middle, and
Lower Chesapeake Bay zones (Methods: Figure 9; Tables 3 and 4). In addition, 1997 SAV
distribution data and ground-truth data are presented for the Delmarva Peninsula Coastal Bays zone:
Chincoteague, Sinepuxent, Assawoman, Isle of Wight, and Magothy bays (Figure 9).
The 1997 SAV bed data were edgematched using ARC/INFO CIS software, as were all the historical
SAV bed data, in order to bring separately digitized USGS 7.5 minute topographic quadrangle SAV
coverages into one unified coverage for the entire Chesapeake Bay (Methods; VIMS SAV GIS
Database; Orth et al, 1996). Therefore, SAV distribution data presented in this report reflect
edgematching adjustments, and may differ from previously published data for years derived from
separate coverages which were not edgematched (i.e., Orth et al., 1992, 1993. and 1994).
SAV distribution data for 1997 and 1996 are presented in hectares: by quadrangle (Table 5); by
Chesapeake Bay zones and by the Delmarva Peninsula Coastal Bays zone (Figure 2); by CBP segment
and by zone (Figures 3,4, and 5; Table 6); by USGS 7.5 minute quadrangles for each CBP segment
and for the Delmarva Peninsula Coastal Bays zone (Table 7); by CBP segment and the Delmarva
Peninsula Coastal Bays zone (also given in acres) (Table 7). Distribution data for 1997 and 1996 by
SAV Density Classes are presented in hectares for each CBP segment (Figures 3, 4, and 5; Table 8)
and for the Delmarva Peninsula Coastal Bays zone (Table 8). Distribution data for 1997 and 1996
by Density Classes are presented in hectares for the zones of Chesapeake Bay and for the Delmarva
Peninsula Coastal Bays zone (Table 9). Quadrangle maps annotated with all 1997 SAV beds and
ground-truth data are presented in Appendix B, and 1997 ground-truth data are also tabulated in
Appendix D. The calculated areas for individual 1997 SAV beds for each quadrangle are tabulated
in square meters in Appendix C.
The 1997 SAV data are summarized, compared with 1996 data, and are discussed relative to their
zones. The seventy-eight CBP segments and the Delmarva Peninsula Coastal Bays zone are
discussed, and 1997 data are compared with data from 1996 and other pertinent years. The 1997
distribution of SAV is plotted on maps of each CBP segment and of the Delmarva Peninsula Coastal
Bays zone; and distribution data for 1971 -1997 are graphed by CBP segment, by year, and by Density
Classes in insets within these figures. The following CBP segments are not graphed because they had
no SAV beds mapped from 1971-1997: BACOH, CHSOH, CHSTF, CHOOH, CHOTF, RHDMH,
NANMH, NANOH, NANTF, WICMH, POCOH, POCTF, WBRTF, RPPOH, RPPTF, ELIPH,

numbered rectangles (refer to Table 2 for quadrangle names listed by VIMS map number). Specific
place names not found on the CBP segment plots are on quadrangle maps for that segment in
Appendix B. A key for the 1997 CBP segment plots is shown in Figure 10. In the graphs of yearly
SAV data, "partial data" refers to those instances when data for only a portion of a CBP segment is
available for a particular year. SAV bed density classification is explained in the Methods section.
1997 SUMMARY
Chesapeake Bay
SAV in Chesapeake Bay increased 9% in 1997, to a total of 28,031.75 hectares mapped from aerial
photography, a 2,336.18 hectare increase from the 25,695.57 hectares mapped in 1996, and the
second consecutive year SAV increased following two years of decreasing SAV (1994 and 1995)
(Figures 1 and 2b; Table 6; VIMS SAV CIS Database). The 1997 level of SAV achieved 61% of the
Tier I goal for Chesapeake Bay (Figures 1 and 2b; Table 6; VIMS SAV CIS Database; CBP). SAV
also increased in all three zones of Chesapeake Bay in 1997: 27%, 8%, and 3% in the Upper, Middle,
and Lower Bay zones, respectively (Figure 2b; Table 6;VIMS SAV GIS Database).

-------
1997
In 1997, SAV in the Bay increased in thirty-three CBP segments (Upper zone: CB1TF, ELKOH,
BOHOH, SASOH, CB2OH, CB3MH, GUNOH, MIDOH, CHSMH, MAGMH; Middle zone:
SEVMH, SOUMH, EASMH, CB4MH, CHOMH1, CHOMH2, LCHMH, PAXMH, PAXOH,
HNGMH, MANMH, BIGMH, POTMH, POTOH, MATTF, PISTF, CB5MH; and Lower zone:
PIAMH, CB7PH, MOBPH, YRKPH, JMSPH, JMSMH) compared to twenty- nine CBP segments
in 1996 (Upper zone: CB1TF, BOHOH, CB2OH, CB3MH, BSHOH, GUNOH, MIDOH, PATMH,
MAGMH; Middle zone: SEVMH, SOUMH, EASMH, CHOMH1, LCHMH, PAXOH, PAXTF,
POTMH, POTOH, POTTF, MATTF, PISTF, CB5MH; and Lower zone: RPPMH, CRRMH,
CB7PH, YRKPH, JMSPH, LYNPH, CB8PH) (Figures 3,4, and 5; Tables 6 and 7; VIMS SAV CIS
Database). In 1996 and 1997, twenty-one of the same CBP segments had increases (Tables 6 and
7; VIMS SAV GIS Database).
In 1997, SAV decreased in twelve CBP segments (Upper zone: NORTF, BSHOH, PATMH; Middle
zone: PAXTF, POCMH, TANMH, POTTF; Lower zone: RPPMH, CRRMH, CB6PH, LYNPH,
CB8PH) compared to thirteen CBP segments in 1996 (Upper zone: NORTF, ELKOH, SASOH,
CHSMH; Middle zone: HNGMH, FSBMH, MANMH, BIGMH, POCMH, TANMH; Lower zone:
PIAMH, CB6PH, MOBPH) (Figures 3, 4, and 5; Tables 6 and 7; VIMS SAV GIS Database). In
1996 and 1997, four of the same CBP segments had decreases (Tables 6 and 7; VIMS SAV GIS
Database).
In 1997, thirty-two CBP segments were unvegetated (Upper zone: C&DOH, BACOH, CHSOH,
CHSTF; Middle zone: RHDMH, WSTMH, CHOOH, CHOTF, FSBMH, NANMH, NANOH,
NANTF, WICMH, POCOH, POCTF; and Lower zone: RPPOH, RPPTF, YRKMH, MPNOH,
MPNTF, PMKOH, PMKTF, ELIPH, SBEMH, JMSOH, CHKOH, JMSTF, APPTF, ELIMH,
LAFMH, WBEMH, EBEMH) compared with the same thirty-two CBP segments in 1996, plus four
additional ones (Middle zone: CB4MH, CHOMH2, PAXMH, and Lower zone: JMSMH) (Figures
3, 4, and 5; Tables 6 and 7). [The main stem Upper and Middle Rappahannock River (RPPOH and
RPPTF), Middle York River (YRKMH), Upper and Lower Mattaponi and Pamunkey rivers
(MPNOH, MPNTF, PMKOH, PMKTF), Upper and Middle James River (JMSTF and JMSOH), and
the Elizabeth River segments have been devoid of SAV for years and are not currently photographed
(Methods; Figure 6)]. In 1997, no CBP segments were unvegetated which had been vegetated in
1996; compared to 1996, when one CBP segment (Middle zone: FSBMH), which was vegetated in
1995, was unvegetated in 1996 (Tables 6 and 7; VIMS SAV GIS Database). In 1997, four CBP
segments were vegetated which had been unvegetated in 1996 (Middle zone: CB4MH, CHOMH2,
PAXMH; and Lower zone: JMSMH), compared to 1996, when two CBP segments were vegetated
which had been unvegetated in 1995 (Upper zone: BSHOH and PATMH) (Tables 6 and 7; VIMS
SAV GIS Database).
Overall in Chesapeake Bay, SAV classified as dense (Class 4) increased in 1997, although some
individual segments had decreases (Tables 8 and 9). In the Bay in 1997, 50% (13,934.52 hectares)
of SAV was categorized as dense, compared to 43% (10,964.44 hectares) in 1996 (Table 9). Also,
11% (3,157.37 hectares) was moderate (Class 3) in 1997, compared to 19% (4,939.35 hectares) in
65
-------
SAV
1996 (Table 9). The percentage of SAV decreased in 1997 in combined Density Classes 3 and 4,
61 % in 1997, compared to 62% in 1996, but in terms of the absolute number of hectares, combined
Density Classes 3 and 4 in 1997 had 17,091.89 hectares SAV, or 1,188.10 hectares more than in
1996 (15,903.79 hectares) (Table 9). In the Bay in 1997, 19% (5,201.54 hectares) of SAV was
sparse (Class 2) in 1997, compared to 22% (5,649.75 hectares) sparse in 1996; 20% (5,738.32
hectares) was very sparse (Class 1) in 1997, compared to 16% (4,142.03 hectares) very sparse in
1996 (Table 9). SAV in combined Density Classes 1 and 2 increased in 1997, constituting 39%
(10,939.86 hectares) of SAV in 1997, compared to 38% (9,791.78 hectares) in 1996 (Table 9).
Upper Bay Zone
In the Upper Bay zone in 1997, SAV increased 27% (945.1 1 hectares), to 4,439.21 hectares, 16%
of the Bay total, and 61% of the Tier I goal of 7,240.18 hectares (in 1996, SAV increased 169.84
hectares) (Figure 2b; Tables 6 and 7; VIMS SAV CIS Database; CBP). Increases in 1997 for some
CBP segments of the Upper zone offset decreases in other CBP segments of this zone (Tables 6 and
7). SAV increased in ten CBP segments in the Upper Bay zone in 1997, decreased in three, and four
were unvegetated, compared to 1996, when SAV increased from 1995 levels in nine CBP segments,
decreased in four, and four were unvegetated (Figure 3; Tables 6 and 7; VIMS SAV GIS Database).
Of the ten CBP segments in the Upper zone with increases of SAV in 1997, seven also increased in
1996 (CB1TF, BOHOH, CB2OH, CB3OH, GUNOH, MIDOH, MAGMH); of the three CBP
segments of the Upper Bay zone which decreased in 1997, one also decreased in 1996 (NORTF); and
of the four CBP segments of the Upper Bay zone which were unvegetated in 1997, the same four also
were unvegetated in 1996 and remained unvegetated from 1995 (C&DOH, BACOH, CHSOH,
CHSTF) (Tables 6 and 7; VIMS SAV GIS Database).
In the Upper Bay zone in 1997, SAV classified as dense increased: 31% (1,395.91 hectares) was
dense in 1997, compared to 26% (915.51 hectares) dense in 1996 (Table 9). However, SAV
classified as moderate decreased: 6% (263.60 hectares) was moderate in 1997, compared to 8%
(267.71 hectares) moderate in 1996 (Table 9). In 1997, sparse SAV increased: 14% (631.83
hectares) was classified as sparse in 1997, compared to 12%' (408.12 hectares) sparse in 1996 (Table
9). The percentage of SAV classified as very sparse decreased in 1997, but the absolute number of
hectares increased: 48% (2,147.86 hectares) was very sparse in 1997, compared to 54% (1,902.76
hectares) very sparse in 1996 (Table 9). The percentage SAV in combined Density Classes 1 and 2
decreased in 1997, but the absolute number of hectares actually increased: SAV in combined Density
Classes 1 and 2 constituted 63% (2,779.69 hectares), compared to 66% (2,310.88 hectares) in 1996
(Table 9). SAV in combined Density Classes 3 and 4 increased, constituting 37% (1,659.51 hectares)
of SAV in 1997, compared to 34% (1,183.22 hectares) in 1996 (Table 9).

1997
Middle Bay Zone
In the Middle Bay zone in 1997, SAV increased 8% (1,088.58 hectares), to 14,209.23 hectares, 51 %
of the Bay SAV total, and 57% of the Tier I goal of 25,026.19 hectares (SAV increased 1,082.87
hectares in 1996) (Figure 2b; Table 6; VIMS SAV CIS Database; CBP). Increases in 1997 for some
CBP segments of the Middle Bay zone offset decreases in 1997 in other CBP segments of this zone
(Tables 6 and 7). In the Middle Bay zone in 1997, there were increases in seventeen CBP segments,
decreases in four, and eleven remained unvegetated, compared to 1996, when there were increases
from 1995 levels in thirteen CBP segments, decreases in six, and fourteen were unvegetated (Figure
4; Tables 6 and 7; VIMS SAV GIS Database).
In the Middle Bay zone in 1997, SAV classified as dense increased: 54% (7,611.14 hectares) was
classified as dense in 1997, compared to 40% (5,295.80 hectares) dense in 1996 (Table 9). Moderate
and sparse SAV decreased in 1997: 13% (1,895.11 hectares) was moderate in 1997, compared to
26% (3,449.98 hectares) moderate in 1996; 21 % (2,940.12 hectares) was sparse in 1997, compared
to 25% (3,289.85 hectares) sparse in 1996 (Table 9). Very sparse SAV increased in 1997: 12%
(1,762.85 hectares) was very sparse in 1997, compared to 8% (1,085.02 hectares) very sparse in
1996 (Table 9). Although the percentages of SAV in the combined Classes 1 and 2, and in the
combined Classes 3 and 4, in the Middle Bay zone in 1997 were the same as those in 1996, the
number of hectares increased: combined Classes 1 and 2 constituted 33% (4,702.97 hectares) of
SAV, compared with 33% (4,374.86 hectares) in 1996; combined Classes 3 and 4 constituted 67%
(9,506.26 hectares) of SAV in 1997, compared with 67% (8,745.79 hectares) in 1996 (Table 9).
Lower Bay Zone
In 1997, SAV increased 3% (302.49 hectares) in the Lower Bay zone, to 9,383.31 hectares, 33% of
the Bay SAV total (SAV increased 191.08 hectares in 1996) (Figure 2b; Table 6). The 1997 Lower
Bay zone SAV level was 68% of the Tier I goal of 13,755.17 hectares (VIMS SAV GIS Database;
CBP). Increases in 1997 for some CBP segments of the Lower Bay zone offset decreases in 1997
in other CBP segments of this zone (Tables 6 and 7). In the Lower Bay zone in 1997, there were
increases in six CBP segments, decreases in five, and seventeen (RPPOH, RPPTF, YRKMH,
MPNOH, MPNTF, PMKOH, PMKTF, ELIPH, ELIMH, LAFMH, WBEMH, EBEMH, SBEMH,
JMSOH, CHKOH, JMSTF, APPTF) remained unvegetated, compared to 1996, when there were
increases from 1995 levels in seven CBP segments, decreases in three, and eighteen remained
unvegetated (RPPOH, RPPTF, YRKMH, MPNOH, MPNTF, PMKOH, PMKTF, ELIPH, ELIMH,
LAFMH, WBEMH, EBEMH, SBEMH, JMSMH, JMSOH, CHKOH, JMSTF, APPTF) (Figure 5;
Tables 6 and 7; VIMS SAV GIS Database).
In the Lower Bay zone in 1997, SAV classified as dense increased: 53% (4,927.46 hectares) was
dense in 1997, compared to 52% (4,753.13 hectares) dense in 1996 (Table 9). Moderate and sparse
SAV decreased in 1997: 11% (998.65 hectares) was moderate in 1997, compared to 13% (1,221.65

SAV
hectares) moderate in 1996; 17% (1,629.60 hectares) was sparse in 1997, compared to 21%
(1,951.78 hectares) sparse in 1996 (Table 9). Very sparse SAV increased in 1997: 19% (1,827.60
hectares) was very sparse in 1997, compared to 13% (1,154.25 hectares) very sparse in 1996 (Table
9). In the Lower Bay zone in 1997, SAV in combined Classes 3 and 4 decreased in 1997: combined
Classes 3 and 4 constituted 63% (5,926.11 hectares) of SAV in 1997, compared to 66% (5,974.78
hectares) in 1996 (Table 9). SAV in combined Classes 1 and 2 increased in 1997, constituting 37%
(3,457.20 hectares) of SAV in 1997, compared to 34% (3,106.04 hectares) in 1996 (Table 9).
The Delmarva Peninsula Coastal Bays Zone
In the Delmarva Peninsula Coastal Bays zone in 1997, SAV distribution increased 23% (1,042.28
hectares) over 1996, to 5,598.37 hectares (Tables 6, 7, and 9). In 1997, the percentage of SAV
classified as dense (62%) remained the same as in 1996 (62%), however, in terms of the absolute
number of hectares, there were 665.78 hectares more in Density Class 4 in 1997 than in 1996 (Tables
8 and 9). The percentage of SAV classified as moderate in 1997 decreased, as well as the absolute
number of hectares: 4% (217.93 hectares) was classified as moderate in 1997, compared to 12%
(565.28 hectares) in 1996 (Tables 8 and 9). The percentage of SAV in combined Density Classes 3
and 4 decreased in 1997, but the absolute number of hectares increased 318.43 hectares over 1996:
combined Density Classes 3 and 4 constituted 66% (3,685.80 hectares) of the SAV in 1997,
compared to 74% (3,367.37 hectares) in 1996 (Table 9). The percentages of sparse and very sparse
SAV both increased in 1997, as well as the absolute number of hectares for these categories: 26%
(1,447.66 hectares) was sparse in 1997, compared to 22% (991.03 hectares) in 1996; and 8% (464.91
hectares) was very sparse in 1997, compared to 4% (197.70 hectares) in 1996 (Table 9). SAV in
combined Density Classes 1 and 2 increased in 1997, constituting 34% (1,912.57 hectares) of the
SAV in 1997, compared to 26% (1,188.73 hectares) in 1996 (Table 9).

1997
DISCUSSION OF CBP SEGMENTS ARRANGED WITHIN ZONES
UPPER BAY ZONE
NORTHERN CHESAPEAKE BAY AND ASSOCIATED TRIBUTARY SEGMENTS
Northern Chesapeake Bay (CB1TF)
Northern Chesapeake Bay (CB1TF) had 2,489.99 hectares of SAV in 1997, 343.22 hectares (16%)
more than in 1996 (Figure 11; Tables 6 and 7). The 1997 level is the second highest recorded; the
highest level for CB1TF in the survey's history was the 2,710.85 hectares recorded in 1994, which
was, however, followed by a 614.22 hectare decrease in 1995 (Figure 11; VIMS SAVGIS Database).
The 1997 CB1TF total of SAV was 80% of the Tier I goal of 3,112.24 hectares (Figure 11; CBP).
CB 1TF had 9% of the SAV in Chesapeake Bay in 1997, compared to 8% in 1996, and had the largest
percentage of SAV in the Upper Bay Zone, as in 1996 (56% in 1997; 61% in 1996) (Figure 11).
The density of SAV in CB 1TF changed only slightly in 1997: sparse SAV increased seven percentage
points while very sparse SAV decreased eight percentage points (Figure 11; Table 8). In 1997,10%
was classified dense, 3% moderate, 11% sparse, and 75% very sparse, compared with 10% dense,
3% moderate, 4% sparse, and 83% very sparse in 1996 (Figure 11; Table 8). CB 1TF had essentially
the same pattern since 1984: very sparse SAV constituting more than 75%, and lesser amounts
distributed in the other three Density Classes (Figure 11; VIMS SAV GIS Database).
SAV beds were located in six main areas of CB 1TF: 1) both shores of the Susquehanna River from
Robert Island to the mouth; 2) a large, very sparse area in the Susquehanna Flats; 3) the western
shore from Concord Point to Swan Creek and Battery Island; 4) east of Stump Point at Mill Creek,
Furnace Bay, Baker Cove, High Point, and Carpenter Point; 5) the Aberdeen Proving Ground area,
including Swan Creek, both shores of the Spesutie Narrows, and Mosquito and Back creeks, as well
as Spesutie Island along Sands Cove, below Locust Point, and above Bear Point; and 6) Pond Creek
on the end of Grove Neck on the eastern shore (Figure 11; Appendix B: Maps 2, 3, 8, 9, 10).
In 1997, the areas of largest increase of SAV in CB1TF were on the western shore, in very sparse
to sparse beds south and offshore of Havre de Grace between Concord Point and Battery Island, and
on the northern shore, in Baker Cove (Figure 11). The increase in the large bed south of Havre de
Grace accounted for more than 90% of the increase in this segment. This large, predominately very
sparse area was vegetated all the way to the mouth of Swan Creek in 1994, but was unvegetated in
1995 and 1996, and accounted for most of the decrease in 1995 from the 1994 level in CB1TF
(Figure 11; VIMS SAV GIS Database). Other, smaller increases occurred: on the western shore, in
the north end of Swan Creek and around Spesutie Island; on the northern shore, in the Susquehanna
River and at Carpenter Point; and on the eastern shore, in Pond Creek (Figure 11).

1997
The largest declines occurred: on the eastern side of Furnace Bay; within the moderate to dense SAV
area immediately south of Havre de Grace; in Swan Creek and along Swan Creek Point; around
Battery Island; and on the eastern side of Spesutie Island south of Locust Point (Figure 11; Appendix
B: Maps 3, 8, 9).
Stan Kollar of Harford Community College, the Citizens' survey, and the USAEC/ARL staff of
Aberdeen Proving Ground reported eight species in CB1TF in 1997: M. spicatum, H. verticillata,
C. demersum, E. canadensis, Heteranthera dubia, V. americana, Najas minor, and Najas flexilis
(Appendices B and D: Maps 2, 3, 4, 8, 9).
Stan Kollar reported the following species: M. spicatum, H. verticillata, C. demersum, and N. minor
by Robert Island in the Susquehanna River; M. spicatum, C. demersum, H. dubia, H. verticillata, N.
minor, V. arnericana, and N. flexilis on both shores of the Susquehanna River; M. spicatum, H.
verticillata, C. demersum, H. dubia, and V. arnericana south of Havre de Grace; M. spicatum, H.
verticillata, C. demersum, H. dubia, V. arnericana, N. minor, and N. flexilis in the Furnace Bay area;
M. spicatum in the Susquehanna Flats and between High Point and Carpenter Point; V. americana,
M. spicatum, and H. verticillata in Pond Creek of Grove Neck; and M. spicatum, V. americana, and
H. dubia in the Battery Island area (Appendices B and D: Maps 2, 3, 9).
The USAEC/ARL staff reported: M. spicatum in Swan Creek; and M. spicatum, H. verticillata, C.
demersum, N. minor, and V. americana in Spesutie Narrows (Appendices B and D: Maps 8, 9).
The Citizens reported: E. canadensis, H. verticillata, M, spicatum, C. demersum, and V. americana
in the Susquehanna River; C. demersum, M. spicatum, and V. americana in Chesapeake Bay; and
M. spicatum and V. americana at Turkey Point of Elk Neck (Appendices B and D: Maps 2, 3, 4, 9).
Northeast River (NORTF)
In NORTF in 1997,4.98 hectares of SAV were mapped, a 6% decline from 1996; the 1997 level was
66% of the 7.54 hectare Tier I goal and was 37% less than the highest level recorded by the aerial
survey, 7.96 hectares in 1994 (Figure 11; Tables 6 and 7; VIMS SAV GIS Database; CBP).
Although SAV has decreased each year since 1994 (6.86 hectares in 1995; 5.30 hectares in 1996),
density of SAV has actually increased each year since then: in 1994, 75% was very sparse and 25%
was moderate; nearly 100% was classified as sparse in 1995; 100% was classified as moderate in
1996; and 100% was classified as dense in 1997 (Figure 11; Table 8; VIMS SAV GIS Database).
In NORTF, only one bed was mapped in 1997 as well as in 1996 and 1995, that being at Cara Cove
(Figure 11; Appendix B: Map 4; VIMS SAV GIS Database). This bed had also been mapped in 1994
as well, but there was also one additional bed that year near the city of North East (VIMS SAV GIS
Database).

SAV
The Citizens' survey reported M. spicatum south of Seneca Point (Appendices B and D: Map 4).
ELK AND BOHEMIA RIVERS AND CHESAPEAKE & DELAWARE CANAL
Elk River (ELKOH)
In ELKOH, 67.44 hectares were mapped in 1997, an increase of 54% over 1996, and 15% of the
447.29 hectare Tier I goal (Figure 12; Tables 6 and 7; CBP). The 1997 level was the second lowest,
and the 1996 level was the lowest, since the highest level of 355.81 hectares was recorded by the
aerial survey in 1990 (Figure 12; VIMS SAV GIS Database).
SAV density also increased in ELKOH in 1997: 17% of the SAV was classified dense, 20%
moderate, 54% sparse, and 9% very sparse, compared to 12% dense in 1996, 9% moderate, 36%
sparse, and 43% very sparse (Figure 12; Table 8).
In ELKOH, new SAV growth was mapped in coves along the western shore, as in the area of Sandy
Hill Camp, and on the eastern shore in Cabin John Creek, along Pearce and Town Point necks, along
the shore south of Herring Island, and at Welch Point (Figure 12). Declines were noted in portions
of some coves of the western shore and above Welch Point on the eastern shore (Figure 12).
In 1997, five species were reported from ground-truth surveys in ELKOH: Stan Kollar reported M.
spicatum, H. verticillata, and V. americana on both the eastern and western shores and P. pectinatus
as well on the western shore (Appendices B and D: Maps 4 and 10). The Citizens' survey and Stan
Kollar reported M. spicatum in the area of Town Point Neck on the eastern shore and on the opposite
shore in Piney Creek Cove; Citizens also reported Potamogeton crispus and V. americana in Piney
Creek Cove (Appendices B and D: Map 4).
Bohemia River (BOHOH)
SAV in BOHOH increased 20%, to 15.09 hectares, in 1997, and achieved the highest level in the
history of the aerial survey as well as 87% of the Tier I goal of 17.32 hectares (Figure 12; Tables 6
and 7; VIMS SAV GIS Database; CBP).
In 1997, SAV density also increased in BOHOH: 71% was classified sparse and 29% very sparse,
compared to 32% sparse and 68% very sparse in 1996 (Figure 12; Table 8).
Largest increases of SAV in BOHOH were on the south shore of the river in Veazy Cove and at the
river's mouth, while the largest decreases were on the north shore at Rich Point and at the mouth
(Figure 12; Map 10).
Stan Kollar reported M. spicatum near Rich Point along Town Point Neck, and H. verticillata, V.
americana, and M. spicatum in Veazy Cove (Appendices B and D: Map 10).

SAV
Chesapeake & Delaware Canal (C&DOH)
The Chesapeake & Delaware Canal, C&DOH, had no SAV mapped in 1997 (Figure 12; Tables 6 and
7). The only SAV ever mapped in C&DOH was the 0.62 hectares in 1978 that established the Tier
I goal (Figure 12; VMS SAV GIS Database; CBP).
There was no ground-truth data reported for C&DOH in 1997 (Appendix D).
UPPER CHESAPEAKE BAY AND ASSOCIATED TRIBUTARY SEGMENTS
Upper Chesapeake Bay (CB2OH)
SAV in CB2OH increased to 110.19 hectares of SAV mapped in 1997,300% more than in 1996, and
the second highest level recorded by the aerial survey (127.49 hectares were mapped in 1985) (Figure
13; Tables 6 and 7; VMS SAV GIS Database). CB2OH in!997 had the highest percentage increase
of SAV of the segments in the Upper Bay zone, as well as the third highest percentage increase of
the segments in the entire Chesapeake Bay, and achieved 41% of the Tier I goal of 266.97 hectares
(Figure 13; VMS SAV GIS Database; CBP).
In 1997, SAV density decreased in CB2OH: 37% was classified as dense, 30% as moderate, 12% as
sparse, and 20% as very sparse, compared to 55% dense, 29% moderate, 16% sparse, and 0% very
sparse in 1996 (Figure 13; Table 8).
Increases were mapped on the western shore of CB2OH in Delph, Little Romney, Boone, and
Browns creeks, and by Fords and Weir points; on the eastern shore of Pooles Island; and on the
eastern shore of CB2OH in Fairlee, Churn, and Still Pond creeks and Codjus Cove (Figure 13;
Appendix B: Maps 8, 13, 14, 15, 16). Decreases were mapped on the western shore of CB2OH in
a cove north of Browns Creek and in Romney Creek (Figure 13; Appendix B: Maps 8, 13).
Seven species were reported from ground-truth surveys: USAEC/ARL staff reported H. verticillata,
M. spicatum, V. americana, and C. demersum in Romney, Little Romney, and Delph creeks, and E.
canadensis, Z. palustris, C. demersum, M. spicatum, and V. americana by Weir Point; the Citizens'
survey reported M. spicatum and P. crispus in Churn Creek, and M. spicatum, P. crispus, and V.
americana in Worton Creek(Appendices B and D: Maps 8, 14, 15).
Sassafras River (SASOH)
SAV in SASOH increased 10% from 1996, to 110.78 hectares in 1997, and achieved 67% of the Tier
I goal of 164.71 hectares, surpassed for the only time in the history of the aerial survey in 1995
(Figure 14; Tables 6 and 7; VMS SAV GIS Database; CBP).
The SAV classified as dense, and that classified as moderate, both decreased in SASOH in 1997:15%

was classified as dense, 0% as moderate, 34% as sparse, and 51% as very sparse, compared to 48%
dense in 1996, 11% moderate, 40% sparse, and 1% very sparse (Figure 14; Table 8). SAV was
concentrated in the lower Sassafras River along both shores, including Money, Lloyd, Turner, and
Freeman creeks (Figure 14). Increases were mapped on both shores of the Sassafras River, but
increases as well as decreases were mapped in the areas of Money, Lloyd, Freeman, Cox, and Turner
creeks, and Yapp and Gut marshes (Figure 14; Appendix B: Maps 9, 10, 16, 17).
In 1997, Stan Kollar reported four species in SASOH: M. spicatum along the north shore of the
Sassafras River and in Money Creek; M. spicatum, C. demersum, and H. verticillata in the Yapp
Marsh area; M. spicatum, C. demersum, H. verticillata, and V. americana in the area of Lloyd Creek;
M. spicatum in Turner Creek; and M. spicatum, V. americana, and H. verticillata in Freeman Creek
(Appendices B and D: Maps 9, 10, 16, 17).
BUSH, GUNPOWDER, MIDDLE, AND BACK RIVER SEGMENTS
Bush River (BSHOH), Gunpowder River (GUNOH), Middle River (MIDOH), and Back River
(BACOH)
In the Gunpowder River segment (GUNOH) and Middle River segment (MIDOH) in 1997, SAV was
mapped at higher levels than in 1996, with SAV in GUNOH reaching the highest level ever surveyed
(Figure 15; Tables 6 and 7; VIMS SAV GIS Database). SAV decreased in the Bush River segment
(BSHOH) in 1997, however, the level exceeded the Tier I goal and was the second highest level ever
recorded by the survey (Figure 15; Tables 6 and 7; VIMS SAV GIS Database; CBP). The Back
River segment (BACOH) had no SAV mapped in 1997, as in every previous year of the aerial survey
(Figure 15; Tables 6 and 7; VIMS SAV GIS Database). BSHOH and GUNOH are the only two CBP
segments in the Upper Bay zone, and are two of only six CBP segments in Chesapeake Bay, which
exceeded their Tier I goals in 1997 (Figure 15; Tables 6 and 7; VMS SAV GIS Database; CBP).
MIDOH had the second highest percentage increase of SAV of all the CBP segments in the Upper
Bay zone and the fourth highest percentage increase of SAV of all CBP segments in Chesapeake Bay
(Tables 6 and 7).
Bush River (BSHOH)
In the Bush River in 1997, there were 34.95 hectares of SAV mapped, a 10% decline from 1996,
when SAV was mapped for the first time since 1992, and when the total SAV, surpassed the Tier I
goal for the first time in the history of the aerial survey (Figure 15; Tables 6 and 7; VIMS SAV GIS
Database). In spite of the decline, the 1997 level was 150% of the Tier I goal of 23.38 hectares
(Figure 15; Tables 6 and 7; VIMS SAV GIS Database; CBP).
In 1997, SAV classified as dense increased in BSHOH: 52% was classified as dense, 14% as
moderate, 32% as sparse, and 1% as very sparse, compared to 16% dense, 69% moderate, 6%
sparse, and 8% very sparse in 1996 (Figure 15; Table 8).

SAV distribution in the Bush, Gunpowder, Middle and Back Rivers
(BSHOH, GUNOH, MIDOH, and BACOH) in 1997. BACOH is not
graphed as no SAV was mapped from 1971-1997. (See Figure 10 for key.)
-------
1997
Decreases of SAV occurred in Towner, Redmon, and Doves coves, by Wilson Point, in Monks and
Church creeks, and along Sandy Point; increases occurred at the mouth of Coopers Creek, along
Monks Island, and in portions of Church Creek, as well as portions of Doves, Redmon, and Towner
coves (Figure 15: Maps 7, 8, 14, 15).
In 1997, the Aberdeen Proving Ground staff reported nine species of SAV in BSHOH (Appendices
B and D: Maps 7, 8, 14, 15). On the south shore, the Aberdeen Proving Ground staff reported: M.
spicatum in Kings Creek and at the mouth of Coopers Creek; M. spicatum, E. canadensis, and C.
demersum in Doves Cove; and M. spicatum, P. crispus, and C. demersum at Wilson Point; and on
the north shore, the Aberdeen Proving Ground staff reported: C. demersum, E. canadensis, M.
spicatum, V. americana, H. verticillata, P. perfoliatus, and Z. palustris in Redmon Cove; M.
spicatum, V. americana, C. demersum, Potamogetonpusillus, andZ. palustris in Abbey Creek; and
M. spicatum along Monks Island (Appendices B and D: Maps 7, 8, 14, 15).
Gunpowder River (GUNOH)
The 1997 level of 637.36 hectares of SAV mapped was a 71% increase over 1996, and not only
surpassed the Tier I goal of 350.21 hectares for the second consecutive year, but also reached the
highest amount reported for GUNOH in the history of the aerial survey (Figure 15; Tables 6 and 7;
VIMS SAV CIS Database; CBP). In 1997, GUNOH had 14% of the SAV in the Upper Bay zone
and 2% of the SAV in the Chesapeake Bay (Tables 6 and 7).
SAV classified as moderate decreased in GUNOH in 1997 while very sparse SAV increased: in 1997,
59% of SAV was dense, 10% moderate, 17% sparse, and 15% very sparse, compared to 58% dense,
22% moderate, 19% sparse, and 1% very sparse in 1996 (Figure 15; Table 8).
Increases in 1997 in GUNOH occurred in the Bird River at the Gunpowder Falls area; on the
shoreline west of Aberdeen Proving Ground; in Swaderick, Watson, Dundee, and Saltpeter creeks;
along Battery Point and Carroll Island by White Oak and Carroll points; and in Cunninghill Cove
(Figure 15; Maps 6, 7, 13, 14). Small decreases occurred in other portions of these areas as well
(Figure 15; Maps 6, 7, 13, 14).
In 1997, ten species, as well as one unidentified SAV species, were reported from ground-truth
surveys in GUNOH (Appendices B and D: Maps 7, 13, 14). On the east shore of GUNOH, the
Citizens' survey reported Z. palustris, and the Aberdeen Proving Ground staff reported M. spicatum,
in the area of Gunpowder Falls; the Aberdeen Proving Ground staff reported M. spicatum, V.
americana, Z. palustris, P. crispus, and P. perfoliatus on the shore west of Aberdeen Proving
Ground; and the Citizens reported E. canadensis in Wright Creek where the Aberdeen Proving
Ground staff also reported M. spicatum; also on the east shore of GUNOH, the Aberdeen Proving
Ground staff reported: M. spicatum, E. canadensis, V. americana, P. crispus, undNajas gracillima
north of Swaderick Creek; M. spicatum and V. americana along Gunpowder Neck south of Days
Point; and V. americana at the mouth of the Gunpowder River; on the west shore, the Aberdeen

SAV
Proving Ground staff reported: E. canadensis and V. americana at Carroll Point; M. spicatum, E.
canadensis, V. americana, P. pusillus, P. perfoliatus, C. demersum, and N. minor in the Dundee and
Saltpeter creeks area; V. americana at Battery Point; and V. americana, M. spicatum, P. perfoliatus,
P. crispus, and C. demersum at Cunninghill Cove; and the Citizens reported an unidentified SAV
species as well as M. spicatum and C. demersum in Railroad Creek (Appendices B and D: Maps 7,
13, 14).
Middle River (MIDOH)
In 1997, MIDOH had 117.37 hectares mapped, a 277% increase from 1996, and 34% of the Tier I
goal of 347.54 hectares (Figure 15; Table 6 and 7; VIMS SAV CIS Database; CBP).
In 1997, SAV classified in dense and moderate categories decreased in MIDOH: 22% was classified
as dense, 16% as moderate, 33% as sparse, and 30% as very sparse, compared to 27% dense in 1996,
54% moderate, 16% sparse, and 2% very sparse (Figure 15; Table 8).
Noticeable increases occurred in areas where no SAV had been present in 1996, by the mouths of
Norman, Hopkins, and Dark Head creeks, in the Galloway creek area, and at the mouth of Middle
River (Figure 15; Map 13). Other large increases occurred in Seneca and Saltpeter creeks, and in
Hawthorn Cove (Figure 15; Map 14).
In 1997, seven species were reported from ground-truth surveys in MIDOH (Appendices B and D:
Maps 13, 14). The Citizens' survey reported E. canadensis, V. americana, M. spicatum, Z.palustris,
and P. crispus in Stansbury Creek, as well as P. perfoliatus and Z. palustris in Hopkins Creek and
two sites in the Middle River (Appendices B and D: Map 13). The Aberdeen Proving Ground staff
reported E. canadensis, M. spicatum, C. demersum, and V. americana in Saltpeter and Seneca
creeks, and E. canadensis, M. spicatum, and V. americana in Hawthorn Cove (Appendices B and
D:Map 14).
Back River (BACOH)
No SAV was mapped in BACOH in 1997 (Figure 15; Tables 6 and 7). In fact, SAV has never been
mapped in BACOH since the aerial survey began there in 1978 (Figure 15; VIMS SAV GIS
Database). There has been no Tier I goal established for BACOH (Figure 15; CBP).
No ground-truth data was reported for BACOH in 1997.
UPPER CENTRAL CHESAPEAKE BAY AND ASSOCIATED TRIBUTARY SEGMENTS
Upper Central Chesapeake Bay (CB3MH)
SAV in CB3MH increased 2% (6.32 hectares) in 1997, to 370.83 hectares, 53% of the Tier I goal
80
-------
1997
of 697.59 hectares, and 8% of SAV in the Upper Bay zone (Figure 16; Tables 6 and 7; VIMS SAV
GIS Database; CBP). By 1997, SAV in CB3MH had increased for six consecutive years, to the
highest level recorded by this survey since 1984, after falling to its lowest level (22.21 hectares) in
1991 (Figure 16; Tables 6 and 7; VMS SAV GIS Database; CBP).
In 1997, SAV classified as dense in CB3MH increased: 79% was classified as dense, 5% as moderate,
10% as sparse, and 6% as very sparse, compared to 59% dense in 1996, 1% moderate, 31% sparse,
and 9% very sparse (Figure 16; Table 8).
For the most part in CB3MH, the SAV distribution in 1997 remained similar to that in 1996, with
most locations having both some areas of increases as well as other areas of decreases: on the eastern
shore, in the area of Eastern Neck Narrows, in Rock Hall Harbor, in Tavern and Swan creeks, and
in The Haven; and on the western shore, in Shallow Creek (Figure 16).
In CB3MH in 1997, six species and one unidentified species each of Chara and of Najas were
reported from ground-truth surveys in the Eastern Neck Narrows: the USFWS reported P.
pectinatus, P. perfoliatus, Z. palustris, M. spicatum, and E. canadensis; the Patuxent Wildlife
Research Center reported all the latter species as well as R. maritima, an unidentified species of
Chara, and an unidentified species of Najas (Appendices B and D: Map 26).
Patapsco River (PATMH)
SAV decreased 16% in 1997, to 1.93 hectares, 4% of the Tier I goal of 50.22 hectares (Figure 16;
Tables 6 and 7; VMS SAV GIS Database; CBP).
The SAV classified as dense also decreased in PATMH in 1997: 100% was moderate, compared to
2% moderate and 98% dense in 1996 (Figure 16; Table 8).
The decrease of SAV in PATMH occurred in the one bed mapped in 1997, in Ashlar Pond on Bodkin
Neck at the mouth of the Patapsco River (Figure 16: Map 24; VIMS SAV GIS Database).
In PATMH in 1997, the Citizens' survey reported M. spicatum in Tanyard Cove off of Curtis Creek
(Appendices B and D: Map 18).
Magothy River (MAGMH)
In MAGMH, SAV increased 44% from 1996, to 53.48 hectares in 1997, and achieved 23% of the
Tier I goal of 236.73 hectares (Figure 16; Tables 6 and 7; VMS SAV GIS Database; CBP). The
1997 survey year was the fifth consecutive year that SAV was mapped in increasing amounts; no
SAV was mapped the four years prior to 1993 (Figure 16; Tables 6 and 7; VMS SAV GIS
Database).

1997
In MAGMH in 1997, SAV classified as dense increased: 66% was classified as dense, 14% as
moderate, 12% as sparse, 7% as very sparse, compared to 34% dense in 1996, 37% moderate, 12%
sparse, and 17% very sparse (Figure 16; Table 8).
In 1997, SAV in MAGMH was mapped principally in the same areas as in the previous three years
(Figure 16; VIMS SAV GIS Database). Increases for MAGMH were mapped on both shores: on
the north shore, most noticeably west of the mouth of Blackhole Creek and in the Gibson Island area,
including Grays and Cornfield creeks, Tar Cove, Little and Dobbins islands, and the Magothy
Narrows; on the south shore, the Wilson Wharf area, the mouth of Forked Creek, the shore between
Ulmsteads Point and Deep Creek, and in the Little Magothy River (Figure 16; VMS SAV GIS
Database). Decreases were most noticeable at the mouth of Grays Cove, on the east end of Dobbins
Island, and portions of the Magothy Narrows (Figure 16; VIMS SAV GIS Database).
In MAGMH in 1997, there were seven species, one unidentified species oiNajas, and an unidentified
SAV species reported from ground-truth surveys (Appendices B and D: Maps 23,24). The USFWS
reported primarily Z. palustris upstream, west of the mouth of Mill Creek, with two sightings each
of R. maritima and M. spicatum (Appendices B and D: Map 23). On the south shore, from east of
the mouth of Mill Creek to the mouth of Deep Creek, the USFWS reported Z. palustris, P.
perfoliatus, V. americana, R. maritima, and P. pectinatus; and, in the Little Magothy River, M.
spicatum (Appendices B and D: Maps 23, 24). Also on the south shore, the Citizens' survey
reported: Z. palustris in Cool Springs Cove; Z. palustris, P. perfoliatus, and an unidentified SAV
species on the west shore of the mouth of Deep Creek; and M. spicatum in Deep Creek, in the inlet
west of the mouth of Deep Creek, and in the Little Magothy River (Appendices B and D: Map 24).
On the north shore, the USFWS reported: P. pectinatus, P. perfoliatus, and Z. palustris in Blackhole
Creek; Z. palustris in Broad Creek and at Dobbins Island; and R. maritima, P. perfoliatus, V.
americana, M. spicatum, E. canadensis, P. pectinatus, Z. palustris, and one unidentified species of
Najas in the Gibson Island area, including the Magothy Narrows and Cornfield Creek (Appendices
B and D: Map 24). Also on the north shore, the Citizens' survey reported: R. maritima and M.
spicatum in Park Creek; and E. canadensis, M. spicatum, P. perfoliatus, V. americana, and Z.
palustris in the Magothy Narrows and Cornfield Creek area (Appendices B and D: Map 24).
CHESTER RIVER SEGMENTS
Lower Chester River (CHSMH), Middle Chester River (CHSOH), and Upper Chester River
(CHSTF)
SAV was mapped only in the Lower Chester River (CHSMH) in 1997, and ground-truth data was
reported for only CHSMH in 1997 (Figure 17; Tables 6 and 7; VIMS SAV GIS Database).
Historically, CHSMH is the only one of the three Chester River segments to have had SAV mapped
in this aerial survey, although no SAV was mapped in it either in 1980 or in!981 (Figure 17; Tables
6 and 7; VIMS SAV GIS Database). Also, no Tier I goal has been established for either the Middle
Chester River (CHSOH) or the Upper Chester River (CHSTF) (Figure 17; Tables 6 and 7; VMS

Lower Chester River (CHSMH)
In 1997, there were 424.81 hectares of SAV mapped in CHSMH, a 36% increase over the 311.80
hectares in 1996, and only 19.39 hectares less than the high mark of 444.20 hectares recorded in 1995
(Figure 17; Tables 6 and 7; VIMS SAV GIS Database). The 1997 level was 28% of the Tier I goal
of 1,517.81 hectares and was 2% of the Chesapeake Bay SAV total as well as 10% of the Upper Bay
zone SAV total (Figure 17; Tables 6 and 7; VIMS SAV GIS Database; CBP).
In 1997, SAV classified as dense in CHSMH increased: 78% was classified as dense, 5% as
moderate, 11% as sparse, and 6% as very sparse, compared to 58% dense in 1996, 8% moderate,
20% sparse, and 14% very sparse (Figure 17; Table 8).
As in 1996, most SAV in CHSMH was located adjacent to Eastern Neck and Eastern Neck Island
(especially near Eastern Neck Narrows), and in tributaries entering the Chester River: Church, Grays
Inn, Langford, Piney, Macum, Jackson, Winchester, and Queenstown creeks (Figure 17; Appendix
B: Maps 21, 26, 32, 33). Increases of SAV were noted in Harrington, Grays Inn, Langford, West
Fork Langford, Queenstown, Winchester, Jackson, Piney, Macum, Church, Durdin, Hall, and
Shipyard creeks; Grays Inn, Little Gum, Nichols, and Belts Bar points and the area below Piney
Point; and Burnt House and Robin coves (Figure 17; Appendix B: Maps 21, 26, 32, 33). The most
noticeable decreases were mapped on the shore from Kent Island Narrows to Blakeford Point; along
Eastern Neck Island; and in portions of Eastern Neck Narrows and Church Creek (Figure 17;
Appendix B: Maps 26, 33).
In CHSMH in 1997, the Patuxent Wildlife Research Center staff, the USFWS, the Maryland DNR,
and the Citizens' survey reported unidentified species of Chara and Najas, and unidentified SAV
species as well as the following eight species: C. demersum, E. canadensis, M. spicatum, P.
pectinatus, P. perfoliatus, R. maritima, V. americana, and Z. palustris (Appendices B and D: Maps
21,26,32,33).

MIDDLE BAY ZONE
MIDDLE CENTRAL CHESAPEAKE BAY AND ASSOCIATED TRIBUTARY AND BAY
SEGMENTS
Middle Central Chesapeake Bay (CB4MH)
SAV in CB4MH increased from 0 hectares in 1996, to 20.28 hectares in 1997, achieving 13% of the
Tier I goal of 152.02 hectares (Figure 18; Tables 6 and 7; VIMS SAV GIS Database; CBP).
In 1997, 18% of the SAV was classified as dense. 75% as moderate, and 7% as sparse (Figure 18;
Table 8).
SAV was mapped in Old Colony Cove where the USEPA reported R. maritima (Figure 18;
Appendices B and D: Map 42, Bed A3). Citizens reported Z. palustris in Fishing and Oyster creeks
(Appendices B and D: Map 31).
Eastern Bay (EASMH)
There were 1,848.32 hectares of SAV mapped in 1997 in EASMH, a 24% increase over 1996 (Figure
18; Tables 6 and 7). SAV has steadily increased each year in the Eastern Bay segment since the 1991
low of 67.93 hectares (Figure 18; VIMS SAV GIS Database). The total hectares of SAV in EASMH
in 1997 was 13% of the SAV in the Middle Bay zone, 7% of the SAV in Chesapeake Bay, and 75%
of the Tier I goal of 2,479.02 hectares (Figure 18; Tables 6 and 7; VIMS SAV GIS Database; CBP).

SAV
In 1997, SAV density in EASMH increased: 59% was classified as dense, 17% as moderate, 13% as
sparse, and 10% as very sparse, compared to 43% dense in 1996, 29% moderate, 21% sparse, and
6% very sparse (Figure 18; Table 8).
In 1997, SAV beds in EASMH persisted in the following locations: the shore and creeks of Kent
Island, including Prospect and Crab Alley bays; adjacent to Parson Island and Piney Neck; the lower
Miles, Wye East, and Wye rivers; the eastern shore between Wyetown and Fairview points; the shore
from Tilghman to Deepwater points; and Eastern Bay at Wades Point (Figure 18; Appendix B: Maps
32, 33, 36, 37). Increases, as well as some decreases, were mapped in most of the latter areas, with
increases offsetting decreases in total hectares (Figure 18).
Increases were largest along Kent Island, from Kents Point to the Philpots Islands and in most creeks;
along Cox and Crab Alley necks; along the southern and eastern sides of Parson Island; in the Wye
River and tributaries, especially Wye Narrows; in the creeks of the lower Miles River; along
Hambleton, Tilghman, Wades, and Long points; and at Ferry Cove by Lowes Point (Appendix B:
Maps 32, 33, 36, 37).
In EASMH in 1997, seven species were reported from ground-truth surveys (Appendices B and D:
Maps 32, 33, 36, 37). The Patuxent Wildlife Research Center reported: R. maritima along the
eastern shore of Eastern Bay, in Wye East River, in Woodland, Leeds, and Hunting creeks of the
Miles River, and in Crab Alley and Cabin creeks; R. maritima and P. pectinatus at Parson Island and
Normans Point; R. maritima, P. perfoliatus, M. spicatum, and E. canadensis in Kirwan Creek; R.
maritima, M. spicatum, and P. perfoliatus in Warehouse Creek; R. maritima, Z. palustris, and P.

CHOPTANK RIVER SEGMENTS
The Mouth of the Choptank River (CHOMH1), Lower Choptank River (CHOMH2), Middle
Choptank River (CHOOH), and Upper Choptank River (CHOTF)
Of the four Choptank River segments, SAV has been mapped only in CHOMH1 and CHOMH2 in
the history of the aerial survey (Figure 19; VIMS SAV GIS Database). SAV levels in CHOMH1
increased for four consecutive years beginning in 1994, reaching, in 1997, the highest level in the
history of the aerial survey (Figure 19; Tables 6 and 7; VMS SAV GIS Database). In 1997, SAV
was mapped in CHOMH2 for the first time since 1993 (Figure 19; Tables 6 and 7; VIMS SAV GIS
Database).
The Mouth of the Choptank River (CHOMH1)
CHOMH1 had 2,792.59 hectares mapped in 1997, 19% more than in 1996, and 93% of the Tier I
goal of 2,990.36 hectares (Figure 19; Tables 6 and 7; VMS SAV GIS Database; CBP). The 1997
level was 20% of the Middle Bay zone SAV total and 10% of Chesapeake Bay SAV total (Tables
6 and 7).
In 1997, SAV density in CHOMH1 increased: 73% was classified as dense, 9% as moderate, 10%
as sparse, and 7% as very sparse, compared to 47% dense in 1996, 34% as moderate, 12% as sparse,
and 7% as very sparse (Figure 19; Table 8).
In 1997, SAV beds persisted and mainly increased along the coves and creeks of both the north shore
of CHOMH1 (including Tilghman Island, Harris and Broad creeks, and the Tred Avon River) and
the south shore of CHOMH1 (including Trippe Bay, Cook Point Cove, and the area from Todds
Point to Castle Haven Point (Figure 19).
On the north shore of CHOMH1, noticeable increases were observed in Blackwalnut Cove at the
south end of Tilghman Island; in Harris and Broad creeks, and their tributary creeks and coves; in
Trippe Creek; and the Tred Avon River and its tributary creeks (Figure 19; Appendix B: Maps 36,
37, 38, 43, 44,45). Noticeable decreases in beds were mapped along Tilghman Island at the mouth
of Blackwalnut Cove, in Dogwood Harbor, and at the mouth and other portions of Harris, Broad,
and Edge creeks; in Irish Creek between Deep and Ferry necks; and at Bachelor Point at the mouth
of the Tred Avon River and in some of its creeks, especially Tar and Flatley creeks (Figure 19;
Appendices B and D: Maps 36, 37, 38, 43, 44, 45).
On the south shore of CHOMH1, increases were mapped from Cook Point to Castle Haven Point;
decreases were in Cook Point Cove and Trippe Bay (Figure 19; Appendices B and D: Maps 51, 52).
In CHOMH1 in 1997, three species, and unidentified SAV, were reported from ground-truth surveys:
the Patuxent Wildlife Research Center reported R. maritima and Z. palustris in Broad Creek; and

they reported R. maritima in Harris, Waterhole, Cummings, Northwest, Grace, San Domingo,
Leadenham, Balls, Irish, Bridge, Edge, Solitude, Tar, Trippe, Maxmore, Peachblossom, and Chapel
creeks; in Todds, Cook Point, Dun, Blackwalnut, Briary, Caulk, Flatley, and Barrett coves; in
Dogwood Harbor; at Todds, Cook, and Camden points; and in the Tred Avon River (Appendices B
and D: Maps 36, 37,43,44,45, 51,52). The USFWS also reported R. maritima in Waterhole Creek
and Blackwalnut Cove (Appendices B and D: Maps 36,43). The Citizens also reported R. maritima
in Broad Creek and in the Tred Avon River, as well as an unidentified SAV; an unidentified SAV in
Balls Creek and in Brannock Bay; and P. pectinatus and Z. palustris in Edge Creek (Appendices B
and D: Maps 36, 37, 43, 44, 51).
Lower Choptank River (CHOMH2)
In CHOMH2 in 1997, 1.76 hectares were mapped compared to 0 hectares in 1996, achieving 1% of
the Tier I goal of 186.95 hectares (Figure 19; Tables 6 and 7; VIMS SAV GIS Database; CBP).
Prior to 1997, SAV had not been mapped by the aerial survey since 1993, when there were 4.02
hectares mapped (Figure 19; Tables 6 and 7; VIMS SAV GIS Database; CBP).
Three SAV beds, all classified as dense, were mapped in Lecompte Creek on the south shore of the
Choptank River in 1997 (Figure 19; Table 8; Map 52).
The Citizens reported Z. palustris in Bolingbroke Creek and west of Chancellor Point in the
Choptank River (Appendices B and D: Map 53).
Middle Choptank River (CHOOH) and Upper Choptank River (CHOTF)
No SAV was mapped in either CHOOH or CHOTF in 1997, nor were there any ground-truth data
reported, as in all the years of the aerial survey (Figure 19; Tables 6 and 7; VIMS SAV GIS
Database). There are no Tier I goals established for either CHOOH or CHOTF (Figure 19; CBP).
Although aerial photography did not show any SAV for CHOOH or CHOTF in 1997, the Citizens'
survey reported Z. palustris for segment CHOOH in the Choptank River at Bow Knee Point and at
the mouth of Hunting Creek (Appendices B and D: Map 46).
Little Choptank River (LCHMH)
LCHMH had 529.39 hectares in 1997, the highest level ever recorded by the aerial survey, a 54%
increase over the second highest in 1996, and 86% of the Tier I goal of 616.39 hectares (Figure 19;
Tables 6 and 7; VIMS SAV GIS Database; CBP). The SAV recorded for 1997 was 4% of the
Middle Bay zone SAV total and 2% of the entire Chesapeake Bay SAV total (Tables 6 and 7).
In 1997, density of SAV increased in LCHMH: 33% was dense, 31 % moderate, 29% sparse, 7% very
sparse, compared to 12% dense in 1996, 33% moderate, 51% sparse, and 4% very sparse (Figure 19;

-------
SAV
Table 8).
In 1997 in LCHMH, SAV beds persisted with both areas of increases and areas of decreases in
different portions of the beds in Hills Point, Oyster, and Cators coves; at Hooper Point; in Madison
Bay; in Slaughter, Brooks, Back, Hudson, Phillips, and Beckwith creeks; and at Cherry Island; and
new beds were mapped in the Little Choptank River, including in Solomon Cove and in Brooks,
Hudson, Slaughter, Fishing, Church, Smith, Gary, and Lee creeks; and at Holland Point (Figure 19;
Maps 51,52, 62).
In LCHMH in 1997, Citizens reported unidentified SAV in Hills Point Cove and Z. palustris in Back
Creek (Appendices B and D: Maps 51, 52).
THE WESTERN TRIBUTARIES: SEVERN, SOUTH, RHODE, AND WEST RIVERS
Severn River (SEVMH)
SAV in SEVMH in!997 increased 12% from 1996, to 123.87 hectares, 66% of the Tier I goal of
187.76 hectares (Figure 20; Tables 6 and 7; VIMS SAV GIS Database; CBP). SAV had increased
each year for four consecutive years from 1994 to 1997; prior to that, no SAV had been mapped
since 1986 (Figure 20; Tables 6 and 7; VIMS SAV GIS Database).
In 1997, SAV density increased in SEVMH: 84% was dense, 9% moderate, 5% sparse, and 2% very
sparse, compared to 62% dense in 1996, 11% moderate, 14% sparse, and 12% very sparse (Figure
20; Table 8).
SAV beds persisted on the south shore, from Herald Harbor downstream to Luce Creek, with new
beds at the mouths of Saltworks, Hopkins, Clements, Brewer, and Mayneider creeks, and in Little
Round Bay; and they persisted on the north shore, from Yantz Creek downstream to Chase Creek,
with new beds in Ringold Cove (Figure 20; Appendix B: Map 23). Noticeable increases to SAV beds
in SEVMH were mapped on the south shore: in the area of Severn Grove, on the shoreline between
Luce and Saltworks creeks; at the mouth of Brewer Creek; on the shoreline near Sherwood Forest;
in Round Bay, including around St. Helena Island and in Little Round Bay; on the shoreline from
Long Point to Kyle Point and to Herald Harbor; and, on the north shore of the Severn River, at the
mouth of Yantz Creek; and on the shoreline from Sullivan Cove to Asquith Creek and to Chase Creek
(Figure 20; Map 23). However, noticeable decreases were mapped as well to other portions of these
same beds: particularly in the Round Bay area, including on the south shore of St. Helena Island, in
little Round Bay; both shores of Long Point to Herald Harbor and at Kyle Point; the shoreline near
Sherwood Forest; the mouth of Clements Creek; the shore by Severn Grove; in Sullivan Cove; the
mouths of Ringold Cove, Asquith Creek, and Chase Creek; and the shoreline by Joyce (Figure 20;
Map 23).

SAV
In SEVMH in 1997, five species were reported from ground-truth surveys: Citizens reported R.
maritima in Sullivan Cove to the west of Kyle and Long points, in Little Round Bay, and in Brewer,
Saltworks, Chase, and Asquith creeks; Citizens reportedZ. palustris, R. maritima, P. perfoliatus, and
M. spicatum in Round Bay; the USFWS reported P. perfoliatus and R. maritima in Asquith Creek,
and R. maritima, Z. palustris, P. perfoliatus, and P. pectinatus to the south of Sullivan Cove; the
MD-DNR reported R. maritima and Z. palustris at the mouth of Brewer Creek, and P. perfoliatus
and R. maritima in Asquith Creek (Appendices B and D: Map 23).
South River (SOUMH)
SAV in SOUMH in 1997 increased 88% from 1996, to 16.35 hectares, 79% of the Tier I goal of
20.59 hectares (Figure 20; Tables 6 and 7; VMS SAV CIS Database; CBP). SAV in SOUMH had
increased each year for four consecutive years from 1994 to 1997; prior to that, no SAV had been
mapped since 1978 (Figure 20; VIMS SAV GIS Database).
In 1997, SAV density in SOUMH increased: 8% was classified as dense, 74% as moderate, 10% as
sparse, and 8% as very sparse, compared to 100% very sparse in 1996 (Figure 20; Table 8).
In SOUMH in 1997, SAV persisted in the areas of Limehouse Cove, and Mayo and Melvin points,
and increases as well as some decreases were mapped in different portions of these beds; new beds
were mapped in the areas of Glebe and Selby bays, Ramsay Lake, and Aberdeen Creek (Figure 20;
Map 30). SAV was not mapped in 1996 at the mouth of Aberdeen Creek, although Z. palustris and
R. maritima had been noted there in 1995 and a small bed had been mapped there in 1994 (VIMS
SAV GIS Database). The most significant decreases occurred at Cedar Point, where an entire bed
mapped in 1996 was not mapped in 1997, and from Melvin Point to the mouth of Almhouse Creek,
where the entire shoreline was unvegetated (Figure 20; Map 30).
In SOUMH in 1997, the Citizens reported: R. maritima and Z. palustris in the South River; in
Brewer, Harness, and Pocahontas creeks; in Selby Bay; at Melvin Point; and in the mouth of Glebe
Bay; and Citizens also reported: Z. palustris in Broad, Gingerville, Church, Crab, Aberdeen, Harness,
Glebe, Almhouse, Warehouse, and Beard creeks; in Larkington, Hardestys, and Limehouse coves;
in Selby and Glebe bays; and in Ramsey Lake (Appendices B and D: Map 30).
Rhode River (RHDMH)
No SAV was mapped in RHDMH in 1997 or in 1996 (Figure 20; Tables 6 and 7; VMS SAV GIS
Database; CBP). The Tier I goal is 5.92 hectares (Figure 20; VMS SAV GIS Database; CBP).
Although no SAV was mapped for this segment in 1997, there was one Citizens' survey sighting of
R. maritima in the area of Beverly Beach (Appendices B and D: Map 30).
94
-------
1997
West River (WSTMH)
No SAV was mapped in WSTMH in 1997 or in 1996 (Figure 20; Tables 6 and 7). The last survey
year SAV was mapped in WSTMH was 1994 when 4.68 hectares were recorded (Figure 20; VIMS
SAV GIS Database). The Tier I goal for WSTMH is 46.75 hectares (Figure 20; VMS SAV GIS
Database; CBP).
There was no ground-truth information reported for this segment in 1997 or in 1996.
LOWER CENTRAL CHESAPEAKE BAY AND ASSOCIATED TRIBUTARY SEGMENTS
Lower Central Chesapeake Bay (CB5MH)
In CB5MH in 1997, SAV increased 4% from 1996, to 736.07 hectares, 38% of the Tier I goal of
1,933.24 hectares (Figure 21; Tables 6 and 7; VMS SAV GIS Database; CBP). The 1997 level is
5% of the Middle Bay zone total SAV and 3% of the Chesapeake Bay total SAV (Figure 21; Tables
6 and 7). The highest previous level was 1,666.81 hectares in 1992 (Figure 21; VMS SAV GIS
Database).
In 1997, SAV density decreased in CB5MH: 2% was dense, 18% moderate, 54% sparse, and 26%
very sparse, compared to 20% dense in 1996, 24% moderate, 32% sparse, and 25% very sparse
(Figure 21; Table 8).
On the western shore in CB5MH in 1997, SAV beds persisted: in Ingram Bay off Dameron Marsh;
in Cloverdale and Dividing creeks; and in Fleets Bay, including Indian and Dymer creeks, and the
mouths of Tabbs and Antipoison creeks; in Little Bay; and at North Point (Figure 21; Maps 106,
112). The most significant decreases occurred: to the north of Little Bay, west of North Point; at
Fleet Point, north of Ingram Bay; and in Balls Creek (Figure 21; Maps 106, 112). New beds were
mapped on the eastern shore along Meekins Neck, including Tar Bay, Barren Island, and Upper
Hooper Island, however, the only 1996 bed mapped on the eastern shore, at Tom Point, was not
mapped in 1997 (Figure 21; Maps 72, 73).
In CB5MH in 1997, the Citizens reported: R. maritima in The Marshes off of Meekins Neck, as well
as near Barren Island off Tar Bay; at Fleet Point north of Ingram Bay; in Dymer Creek; and at North
Point (Appendices B and D: Maps 72, 106, 112). Citizens also reported R. maritima and Z. marina
in the areas east of Dameron Marsh, and in Ball and Cloverdale creeks (Appendices B and D: Maps
72, 106,112).

1997
Honga River (HNGMH)
SAV in HNGMH in 1997 increased 43% over 1996, to 890.51 hectares, 56% of the Tier I goal of
1,599.11 hectares, and 6% of the Middle Bay Zone SAV total (Figure 21; Tables 6 and 7; VMS
SAV GIS Database; CBP).
In 1997, SAV density increased in HNGMH: 13% was classified dense, 31 % moderate, 51 % sparse,
and 4% very sparse, compared to 8% dense in 1996,39% moderate, 47% sparse, and 6% very sparse
(Figure 21; Table 8).
On the eastern shore of HNGMH in 1997, SAV beds persisted at Keenes Point; along Kirwan and
Parks necks; at Asquith and Wroten islands; and around Duck Point Cove (Figure 21; Maps 73,74).
Areas of increases, and other areas of decreases as well, occurred in the persisting beds in all the latter
localities: significant increases were mapped at Keenes Point; Kirwan Neck; Wallace, Worlds End,
Fox, and Charles creeks; and in Lakes, Duck Point, and Fallins coves; while significant decreases
were mapped at the head of the Honga River; on the east end of Wroten Island; along Parks Neck;
and around Duck Point, Norman, and Hopkins coves (Figure 21; Maps 63, 73, 74, 83). On the
eastern shore of HNGMH in 1997, new beds were mapped at the head of the Honga River; in
Wallace and Fox creeks; around Wroten Island; and at Cedar Point on Asquith Island (Figure 21;
Maps 63, 73, 74). On the western shore of HNGMH, many new beds were mapped in 1997 where
no SAV had been mapped in 1996: at the south end of Meekins Neck and along Gunners, Upper
Hooper, and Middle Hooper islands (Figure 21; Map 73).
No ground-truth information was reported for this segment in 1997.
Fishing Bay (FSBMH)
No SAV was mapped and no ground-truth information was reported for this segment in either 1997
or in 1996 (Figure 22; Tables 6 and 7; VIMS SAV GIS Database).
NANTICOKE RIVER SEGMENTS
Lower Nanticoke River (NANMH), Middle Nanticoke River (NANOH), Upper Nanticoke
River (NANTF)
No SAV was mapped for the Nanticoke River segments in 1997 or in any years of the aerial survey,
and no ground-truth data was reported for the Nanticoke River segments in 1997 (Figure 22; Tables
6 and 7; VMS SAV GIS Database). Tier I goals have not been established for NANMH, NANOH,
and NANTF (Figure 22; Tables 6 and 7; VMS SAV GIS Database; CBP).

1997
Wicomico River (WICMH)
No SAV was mapped for WICMH in 1997 or in any years of the aerial survey and no ground-truth
data was reported in 1997 (Figure 22; Tables 6 and 7; VMS SAV GIS Database). No Tier I goals
have been established for WICMH (Figure 22; Tables 6 and 7; VMS SAV GIS Database; CBP).
TANGIER SOUND AND ASSOCIATED TRIBUTARY AND BAY SEGMENTS
Tangier Sound and the Little Annemessex River (TANMH)
SAV in TANMH in 1997 decreased 14% from 1996, to 3,825.57 hectares, 48% of the Tier I goal
of 8,053.10 hectares, 27% of the Middle Bay zone, and 14% of the Bay (Figure 23; Tables 6 and 7;
VMS SAV GIS Database; CBP).
SAV categorized as dense increased in TANMH in 1997, however, very sparse SAV also increased:
49% of SAV was classified dense, 10% moderate, 18% sparse, and 23% very sparse, compared to
36% dense in 1996, 28% moderate, 28% sparse, and 8% very sparse (Figure 23; Table 8).
Although less SAV was mapped in TANMH in 1997 than was mapped there in 1996, the very large
SAV beds persisted with notable decreases, and a few small areas of minor increases, around Smith,
Tangier, Cedar, and Great Fox Islands; and other, smaller beds persisted at Smith, Bloodsworth,
Janes, Hazzard, Little Deal, and Watts islands and in the Little Annemessex River (Figure 23; Tables
6 and 7). The area in TANMH with the largest amount of SAV in 1997 persisted from 1996 but had
large decreases in the contiguous beds extending from the southern end of Smith Island to Upper
Tump, Fishbone, and Thorofare islands, and to Goose Island and Queen Ridge (Figure 23; Appendix
B and C: Maps 99, 100, 107, 179; VMS SAV GIS Database).
Beds disappeared from most of Bloodsworth and South Marsh islands in 1997 (Figure 23; VMS
SAV GIS Database). Specifically, beds mapped in 1996 were not mapped in the following areas in
1997: the south end of Bloodsworth Island as well as Pone, Tigs, and Piney Island coves; Adams and
Holland islands; and Pungers Cove, Muscle Hole, and Sheepshead Harbor on South Marsh Island
(Figure 23; VMS SAV GIS Database). However, there were increases in the one bed persisting at
Okahanikan Cove on Bloodsworth Island and in the two beds persisting at Johnson and Pry coves
on South Marsh Island (Figure 23; VMS SAV GIS Database).
SAV beds around Smith Island persisted but were greatly decreased in size in 1997, however, some
notable increases were mapped at the northern end of Smith Island in Back, Fog Point, and Terrapin
Sand coves; in the Big Thorofare; and in Tyler Creek (Figure 23; VMS SAV GIS Database).
On Tangier and Watts islands, the beds persisted similar to 1996 but with a few small increases,
especially in the Tangier North Channel (Figure 23; VMS SAV GIS Database).

In the Little Annemessex River, SAV beds mapped in 1996 persisted but with notable increases in
1997, and some new beds were mapped in 1997 in Jenkins, Back, and Daugherty creeks of the Little
Annemessex River (Figure 23; VMS SAV CIS Database).
New beds for TANMH in 1997 were also mapped in the Big Thorofare and near Hog Neck on Smith
Island, in Broad Creek by Cedar Island, and at Janes and Hazzard islands (Figure 23).
In 1997, as in 1996, SAV was not mapped in the portion of TANMH on Map 84, the Deal Island
quadrangle, including the mouths of the Nanticoke and Wicomico rivers, and the shore from Long
Point to Little Deal Island (Figure 23; Table 7; Appendix B; VIMS SAV GIS Database).
In TANMH in 1997, two species were reported from ground-truth surveys: the VIMS Field Survey
reported R. maritima from Smith Island in Back Cove, Tyler Creek, and Twitch Cove near Drum
Point; and from Goose Island (Appendices B and D: Maps 91, 99, 100, 107). VMS also noted R.
maritima and Z. marina in the large bed in the Cedar Straits by Cedar Island and in the large bed
north of Queen Ridge by Goose Island (Appendices B andD: Maps 100,107). The Citizens' survey
reported Z. marina in Tyler Creek on Smith Island (Appendices B and D: Map 99).
Manokin River (MANMH)
In MANMH in 1997, SAV increased 602% over 1996, to 56.44 hectares, 0.40% of the Middle Bay
zone SAV total, and 20% of the Tier I goal of 276.20 hectares (Figure 24; Table 6 and 7; VMS SAV
GIS Database; CBP).
SAV density increased slightly in 1997 in MANMH: 44% was moderate and 56% sparse, compared
to 39% moderate in 1996, and 61% sparse (Figure 24; Table 8).
SAV was mapped only along the south shore of MANMH in 1997 (Figure 24; Appendix B: Maps
92,93). SAV beds persisted at Drum Point, and at Goose and Mine creeks with significant increases
(Figure 24; Appendix B: Map 93). New beds were mapped in Drum Point Cove, and at Goose and
Mine creeks (Figure 24; Appendix B: Maps 92, 93).
The Citizens reported R. maritima in Laws Thorofare in MANMH in 1997, although no beds were
mapped in this area (Appendices B and D: Map 84).
Big Annemessex River (BIGMH)
SAV in 1997 in BIGMH increased 63% over 1996, to!43.25 hectares, 1% of the Middle Bay zone
SAV total and 39% of the Tier I goal of 364.52 hectares (Figure 24; Tables 6 and 7; VMS SAV GIS
Database; CBP).
In 1997, SAV density decreased in BIGMH: 65% was moderate, 25% sparse, and 10% very sparse,

compared to 78% moderate in 1996 and 22% sparse (Figure 24; Table 8).
SAV beds were mapped in BIGMH in 1997 on the north shore from Shirtpond Cove to Scott Point,
persisting with significant increases, as well as some smaller decreases, in Shirtpond, Flatland, and
Fords coves (Figure 24; Map 93). New beds were mapped on the north shore in Fords Cove and
south to Scott Point (Figure 24; Map 93). On the south shore of BIGMH, SAV was mapped from
Flatcap Point to Sandy Point, persisting with significant increases, as well as some smaller decreases,
at Janes and Jackson islands, and at Acre, Daugherty, and Jones creeks (Figure 24; Map 93). New
beds were mapped at Flatcap, Long, and Sandy points, and at Daugherty and Jones creeks (Figure
24; Map 93).
There was no ground-truth information reported for this segment in 1997.
POCOMOKE RIVER SEGMENTS
Lower Pocomoke River (POCMH), Middle Pocomoke River (POCOH), and Upper Pocomoke
River (POCTF)
The Lower Pocomoke, POCMH, which includes the Pocomoke Sound, was the only CBP segment
of the Pocomoke River to have SAV mapped in 1997 (Figure 25; Tables 6 and 7).
Lower Pocomoke River (POCMH)
SAV in POCMH in 1997 decreased 19% from 1996, to 529.84 hectares, 4% of the Middle Bay zone
SAV total and 63% of the Tier I Goal of 840.77 hectares (Figure 25; Tables 6 and 7; VIMS SAV
GIS Database; CBP).
SAV density increased in POCMH in 1997: 43% was classified as dense, 2% as moderate, 39% as
sparse, and 15% as very sparse, compared to 30% dense in 1996, 12% moderate, 40% sparse, and
18% very sparse (Figure 25; Table 8).
On the northern shore, SAV beds persisted with some decreases to the beds at Oystershell and
Eastward points (Figure 25; Appendix B: Map 101). On the southern shore, SAV beds persisted with
notable decreases: at Webb, Scott, Halfmoon, Jacks, Marks, Jobes, Cedar, and Lower Bernard
islands; in Beasley Bay; in Doe, Little Back, and Cattail creeks; and in the Thorofare (Figure 25;
Appendix B: Maps 101,102, 108, 109). Some small increases were mapped as well in the vicinity of
these same beds, however, they did not offset the decreases (Figure 25; Tables 6 and 7). Beds
disappeared from Hunting and Bagwell creeks as well as from Upper Bernard Island (Figure 25;
AppendixB: Map 109). New beds were mapped at Guilford and Muddy creeks (Figure 25; Appendix
B:Maps 101,102, 108, 109).

Middle Pocomoke River (POCOH) and Upper Pocomoke River (POCTF)
No SAV was mapped for POCOH and POCTF in 1997 and no ground-truth information was
reported (Figure 25; Tables 6 and 7; VIMS SAV GIS Database). No SAV has been mapped for
POCOH or POCTF in the history of the aerial survey (VIMS SAV GIS Database). No Tier I goals
have been established for POCOH and POCTF (Figure 25; Tables 6 and 7; VIMS SAV GIS
Database; CBP).
PATUXENT RIVER AND WESTERN BRANCH RIVER TRIBUTARY SEGMENTS
Lower Patuxent River (PAXMH), Middle Patuxent River (PAXOH), Upper Patuxent River
(PAXTF), and Western Branch River (WBRTF)
SAV increased in two segments of the Patuxent River (PAXMH, PAXOH) in 1997 and decreased
in PAXTF, however, no SAV was mapped in the Western Branch River segment (WBRTF) (Figure
26; Tables 6 and 7).
Lower Patuxent River (PAXMH)
In PAXMH in 1997, 1.02 hectares were mapped, compared to 1996 and 1995 when there was no
SAV recorded (Figure 26; Tables 6 and 7; VIMS SAV GIS Database). The 1997 level was nearly
1% of the Tier I goal of 143.61 hectares, which has never been reached in the years of the aerial
survey (Figure 26; VMS SAV GIS Database; CBP). The highest level of SAV mapped for this
segment was recorded in 1985 when 53.74 hectares were mapped (Figure 26; VIMS SAV GIS
Database).
All (100%) of the SAV in PAXMH in 1997 was classified as sparse (Figure 26; Table 8).
Only one small SAV bed was mapped in PAXMH in 1997, at the mouth of Hungerford Creek on
Hoopers Neck on the north shore, where The University of Maryland reported P. pectinatus (Figure
26; Appendices B and D: Map 71, Bed A2).
Citizens reported two additional species for PAXMH: Z. palustris on the north shore, in Battle, Saint
Leonard, and Cuckold creeks, off Broomes Island at the mouth of Island Creek, and at Petersons
Point; and M. spicatum on the south shore, in Green Holly Pond (Appendices B and D: Maps 60,
61,70,71).
Middle Patuxent River (PAXOH)
SAV in PAXOH increased 11% from 1996, to 40.08 hectares in 1997, the highest level recorded by

the aerial survey, and well above the Tier I goal of 0.83 hectares (Figure 26; Tables 6 and 7; VIMS
SAV CIS Database; CBP). S AV had increased in PAXOH four consecutive years, 1994-97 (Figure
26; VIMS SAV GIS Database).
In 1997, SAV density in PAXOH increased: 98% was classified as dense and 2% as moderate,
compared to 67% dense in 1996, 29% moderate, and 4% sparse (Figure 26; Table 8).
SAV beds persisted in 1997 on both shores in the upper reaches of PAXOH, north of Friday Creek
where the river broadens; these beds had areas of small increases, as well as some areas of small
decreases, but remained basically the same as in 1996 (Figure 26; Map 41; Orth et al, 1997). One
bed present at the mouth of Cocktown Creek in 1996 was not mapped in 1997 (Appendices B and
D: Map 41; Orth et al, 1997). Three new, small beds were mapped in 1997 (Figure 26; Appendices
B and D: Map 41: Beds A3, B3, E4).
In PAXOH in 1997, the MD-DNR, Patuxent River Park, and the Citizens reported seven species and
four sightings of unidentified species of Najas (Appendices B and D: Map 41). Specifically, from the
western shore of the Patuxent River in PAXOH, the MD-DNR reported N. minor, unidentified
species of Najas, and H. verticillata from the large bed at the mouth of Spice Creek, and at a site by
Milltown Landing; and from the eastern shore of PAXOH, C. demersum and unidentified species of
Najas from new bed E4, and N. minor from bed C4 (Appendices B and D: Map 41). Also from the
eastern shore, the Patuxent River Park reported C. demersum, N. guadalupensis, N. minor, and V.
americana in Hall Creek, and the Citizens reported C. demersum, E. canadensis, P. crispus, and V.
americana in Cocktown Creek (Appendices B and D: Map 41).
Upper Patuxent River (PAXTF)
In PAXTF in 1997, there were 53.16 hectares, a 17% decrease from the high mark of 63.93 hectares
mapped in 1996, but still well above the Tier I goal of 5.64 hectares (Figure 26; Tables 6 and 7;
VIMS SAV GIS Database; CBP). The 1997 level is the third highest recorded in the years of the
aerial survey (Figure 26; VIMS SAV GIS Database). There were 53.73 hectares mapped in 1994;
prior to that only two years had SAV mapped: 1993 (8.78 hectares) and 1985 (5.64 hectares) (Figure
26; VIMS SAV GIS Database).
SAV density increased in PAXTF in 1997: 93% was classified dense, 4% moderate, and 3% sparse,
compared to 51% dense in 1996, 45% moderate, and 4% sparse (Figure 26; Table 8).
In PAXTF in 1997, SAV beds persisted along both shores, including the large beds in Jug Bay, but
noticeable decreases were mapped there as well as in beds located by Iron Pot Landing, by the mouth
of Galloway Creek, and by Bristol Landing in the north above Jug Bay; and in beds located from the
mouth of Lyons Creek, south on both shores to the vicinity of Kings Creek (Figure 26; Appendix B:
Maps 41, 159). SAV disappeared entirely from the western shore, just north of the mouth of Kings
Creek; and from the eastern shore, at the mouth of Kings Branch to the mouth of Lyons Creek

SAV
(Figure 26; Appendix B: Maps 41, 159). A new bed was mapped at the mouth of Mattaponi Creek
(Figure 26; Appendix B: Map 41).
In PAXTF in 1997, eight species were reported as well as unidentified species of Najas and an
unidentified species of SAV (Appendices B and D: Maps 41, 159). The MD-DNR reported H.
verticillata in Jug Bay; and Najas sp. and H. verticillata at the mouth of Mattaponi Creek and from
the bed on the east shore south of Kings Branch (Appendices B and D: Maps 41,159). The Citizens'
survey also reported H. verticillata at the Route 4 bridge crossing and just south of Jug Bay
(Appendices B and D: Map 159). The Patuxent River Park reported: C. demersum, E. canadensis,
H. verticillata, N. minor, N, guadalupensis, P. crispus, P. pusillus, V. americana, and an unidentified
SAV species north of Jug Bay, from the mouth of Western Branch to the mouth of Owens Branch;
H. verticillata andN. minor in Jugs Bay; C. demersum, E. canadensis, H. verticillata, and W. minor
in Lyons Creek; and E. canadensis, C. demersum, H. verticillata, N. minor, and P. crispus in
Mattaponi Creek (Appendices B and D: Maps 41, 159).
Western Branch River (WBRTF)
No SAV was mapped in WBRTF in 1997 or in any years of the aerial survey (Figure 26; Tables 6 and
7; VMS SAV GIS Database). No Tier I goal has been established for WBRTF (Figure 26; CBP).
Five species were reported in 1997 by the Patuxent River Park from WBRTF, in the lower portion
of the Western Branch tributary, near the confluence with Horse Tavern Branch and Charles Branch,
above the confluence with the Patuxent River: C. demersum, E. canadensis, H. verticillata, N. minor,
and Z. palustris (Figure 26; Appendices B and D: Map 159).
POTOMAC RIVER AND TRIBUTARY SEGMENTS
Lower Potomac River (POTMH), Middle Potomac River (POTOH), Upper Potomac River
(POTTF), Mattawoman Creek (MATTF), and Piscataway Creek (PISTF)
SAV in 1997 in the Potomac River as a whole (CBP segments POTMH, POTOH, POTTF, MATTF,
PISTF combined) increased to 2,600.74 hectares, from 2,181.74 hectares in 1996 (Tables 6 and 7;
VIMS SAV GIS Database). [The total SAV in 1995 in the Potomac River as a whole was 1,906.33
hectares, which was the lowest level since 1,862.89 hectares were mapped in 1985 (Tables 6 and 7;
VIMS SAV GIS Database). The highest total of SAV for the Potomac River as a whole was
3,595.80 hectares mapped in 1991 (VIMS SAV GIS Database).]
In the Potomac River in 1997, SAV levels increased over those in 1996 in all CBP segments except
POTTF (Figures 27, 28, 29; Tables 6 and 7). However, changes were complex within CBP
segments: for example, SAV increased in POTMH and POTOH in 1997, but there were some
quadrangles within these CBP segments where SAV decreased in abundance (Table 7: POTMH, Map
88; POTMH, Maps 55, 65). Also, SAV decreased in POTTF in 1997, but there were some

quadrangles within this CBP segment which had increases of SAV (Table 7: POTTF, Maps 28,40).
The density and species composition of SAV beds, as well as their locations, further complicated the
picture of SAV changes in the Potomac River (Figures 27, 28, 29; Tables 6,7, 8; Appendices B, C,
D; VMS SAV GIS Database).
Lower Potomac River (POTMH)
SAV in POTMH in 1997 increased 66% over 1996, to 666.84 hectares, 167% of the Tier I goal of
400.13 hectares, 5% of the Middle Bay zone SAV total, and 2% of the Bay SAV total (Figure 27;
Tables 6 and 7; VMS SAV GIS Database; CBP). This is the second year of the aerial survey that
the SAV level in POTMH exceeded the Tier I goal; the 1996 level was 2.27 hectares above the goal
(Figure 27; Tables 6 and 7; VMS SAV GIS Database; CBP). SAV abundance in POTMH increased
each year since 1993 and, in 1997, reached the highest level recorded since the aerial survey began
(Figure 27; VMS SAV GIS Database). [The lowest surveyed level of SAV in POTMH was 43.12
hectares in 1986 (Figure 27; VMS SAV GIS Database).] However, despite increases in abundance
and density, SAV is still absent in most areas of POTMH, especially the main stern Potomac River
(Figure 27; Tables 6, 7, and 8).
The percentage of SAV classified as dense increased slightly in 1997 in POTMH, however, the
percentage of moderate SAV declined while the sparse and very sparse SAV increased: 66% of SAV
was classified as dense, 11% as moderate, 19% as sparse, and 5% as very sparse, compared to 62%
dense in 1996, 17% moderate, 17% sparse, and 4% very sparse (Figure 27; Table 8).
On the north shore in POTMH in 1997, SAV beds persisted with areas of decreases and areas of
increases: by Lower Cedar Point; in Picowaxen and Cuckold creeks; in Neale and St. Catherine
sounds; in Captico Bay of the Wicomico River; in St. Clements Bay; and in the St. Marys River
including St. George and St. Inigoes creeks (Figure 27; Appendix B: Maps 67, 68, 69,77,78). New
beds were mapped in 1997 on the north shore: near Lower Cedar, Waverly, Lloyd, and Bachelor
Hope points; in Cuckold Creek; in Neale and St. Catherines sounds; in the Wicomico River on both
shores, from the mouth north to Cooksey Point, including Chaptico Bay; in Breton B>ay; and on both
shores of the St. Marys River (Figure 27; Appendix B: Maps 67, 68, 69, 77, 78).
On the south shore in POTMH in 1997, SAV beds persisted with areas of decreases and areas of
increases: along Mathias Neck south of Persimmon Point; in Rosier and Goldman creeks; in Horn's
Marsh of Currioman Bay; and in Nomini and Buckner creeks (Figure 27; Appendix B: Maps 66,67,
77, 78). New beds were mapped on the south shore in Upper Machodoc, Buchner, Nomini, and
Rosier creeks (Figure 27; Appendix B: Maps 66, 77,78). Very small areas of decrease were noted
north of Upper Machodoc Creek, and one bed mapped in 1996 in Lower Machodoc Creek was not
mapped in 1997 (Figure 27; Appendix B: Maps 78, 66).
In POTMH in 1997, eight species and an unidentified species of SAV were reported by the following
ground-truth surveys (Appendices B and D: Maps 57, 58, 66, 67, 77, 78, 87, 88, 89, 96, 97).

1997
Along the south shore of the Potomac River in POTMH in 1997, VIMS reported P. pectinatus to the
north of the Harry Nice Memorial Bridge (Appendices B and D: Map 66). Also on the south shore
of POCMH, the USGS reported: V. americana along Mathias Point Neck; V. americana and P.
perfoliatus along Persimmon Point north of the Harry Nice Memorial Bridge; M. spicatum in
Currioman and Poor Jack creeks off Currioman Bay; Z. palustris and M. spicatum in Currioman Bay,
and in Nomini, Buckner, and Lower Machodoc creeks; Z. palustris in Glebe Harbor and Glebe Creek
off Lower Machodoc Creek, at Lynch Point and in Lodge Creek in the West Yeocomico River, in
Judith Sound, and west of Travis point in Kingscote, Glebe, and Cod creeks and the Coan River
(Appendices B and D: Maps 57, 66, 67, 77, 78, 87, 88, 89, 96, 97).
Also on the south shore in 1997, the Citizens' survey reportedM. spicatum, P. crispus, P. pectinatus,
P. perfoliatus, and V. americana to the north of the Harry Nice Memorial Bridge, and M. spicatum,
P. perfoliatus, and V. americana to the south; P. perfoliatus and V. americana north of the mouth
of Upper Machodoc Creek; P. perfoliatus in Upper Machodoc Creek; M. spicatum at the south end
of Nomini Bay; M. spicatum and Z. palustris in Nomini Creek; and Z. palustris in Glebe and Lower
Machodoc creeks; and an unidentified SAV in Fleets Cove off Hull Creek (Appendices B and D:
Maps 66, 67, 78, 87, 97).
Along the north shore, the USGS reported: M. spicatum and V. americana north of the Harry Nice
Memorial Bridge; and V. americana and P. perfoliatus at the mouth of Popes Creek (Appendices B
and D: Maps 58, 67). Citizens reported: M. spicatum, V. americana, and P. perfoliatus south of the
Harry Nice Memorial Bridge; H. dubia, M. spicatum, and P. perfoliatus in Cuckold Creek; and Z.
palustris to the north of Rose Croft Point in the St. Marys River (Appendices B and D: Maps 67, 80).
VIMS reported R. maritima in the mouth of St. Inigoes Creek (Appendices B and D: Maps 80).
Middle Potomac River (POTOH)
In 1997 in POTOH, SAV increased for the second consecutive year, to 1,206.26 hectares, 16% more
than in 1996, 70% of the Tier I goal of 1,725.78 hectares, 8% of the Middle Bay zone SAV total, and
4% of the Bay SAV total (Figure 28; Tables 6 and 7; VIMS SAV GIS Database; CBP).
In 1997 in POTOH, the percentage of SAV in the dense category decreased, but the absolute number
of hectares was actually greater than in 1996: 69% (829.57 hectares) was classified as dense in 1997,
10% as moderate, 18% as sparse, and 4% as very sparse, compared to 76% (787.62 hectares) dense
in 1996, 3% moderate, 15% sparse, and 6% very sparse (Figure 28; Table 8).
On the south shore of POTOH in 1997, SAV beds persisted, but with large changes, in
Chopawamsic, Potomac, Aquia, and Choptank creeks; along the shore from Quantico to
Chopawamsic Island; along the shore south of Widewater to Youbedamn Landing; at Marlboro Point;
at Belvedere and Somerset beaches; and at Mathias Point (Figure 28; Appendix B: Maps 47, 55, 57,
64, 65, 66). The largest decreases occurred at Chopawamsic Island; along the shore south of
Widewater to Youbedamn Landing; in Aquia Creek; at the mouth of Potomac Creek, west of

Marlboro Point; at Belvedere Beach; at the eastern end of Somerset Beach; in Choptank Creek; and
at Mathias Point (Figure 28; Appendix B: Maps 47, 55, 57, 64, 65, 66).
On the north shore of POTOH in 1997, SAV beds persisted, but also with many changes, in Mallows
and Wades Bay; from Maryland Point north to Blossom Point; in Nanjemoy Creek; from Upper Cedar
Point to Windmill Point; in the Port Tobacco River; and along the eastern shore at the mouth of the
Port Tobacco River (Figure 28; Appendix B: Maps 55, 56, 57, 65). The largest decreases occurred
north of Mallows Bay; in Mallows and Wades bays; at Smith Point; from Thomas Point to Maryland
Point; from Maryland Point to Blossom Point; on both shores of the mouth of Nanjemoy Creek, from
Upper Cedar Point to Windmill Point; and in Goose Creek off the Port Tobacco River (Figure 28;
Appendix B: Maps 47, 55, 57, 65). Other smaller decreases occurred in a few areas of Nanjemoy
Creek and the Port Tobacco River, but these two tributaries had many more areas with much larger
increases (Figure 28; Appendix B: Maps 56, 57).
In POTOH in 1997, twelve species were reported by ground-truth surveys conducted by the USGS,
the USFWS, and the Citizens' SAV Hunt (Appendices B and D: Maps 47, 55, 56, 57, 64, 65, 66).
Hydrilla verticillata was reported extensively by the USGS, either alone or with other species, from
both sides of the Potomac River, and in the tributaries and bays, from the border with POTTF, to
Potomac Creek on the south shore and to a place above Thomas Point on the north shore
(Appendices B and D: Maps 47, 55, 64).
From the south shore of POTOH in 1997, the USGS reported the following species: H. verticillata

Upper Potomac River (POTTF)
In 1997 in POTTF, SAV decreased 14% from 1996, to 554.11 hectares, 21% of the Tier I Goal of
2,591.90 hectares, 4% of the Middle Bay zone SAV total, and 2% of the Bay SAV total (Figure 29;
Tables 6 and 7; VIMS SAV GIS Database; CBP).
In POTTF, the percentage of SAV in the dense and the very sparse categories increased in 1997:73%
was categorized as dense in 1997, 4% as moderate, 11% as sparse, and 12% as very sparse,
compared to 47% dense in 1996, 14% moderate, 34% sparse, and 4% very sparse (Figure 29; Table
8).
SAV in POTTF in 1997 was mapped in the Anacostia River, and on both the eastern and western
shores of the Potomac River, from the D.C. area in the northern part of POTTF, to the southern
boundary of POTTF at Quantico on the western shore, and at Chicamuxen Creek on the eastern shore
(Figure 29; Appendix B: Maps 34, 47, 48). SAV was also mapped in 1997 in the Potomac River
above the confluence with the Anacostia River, where no SAV was mapped in 1996, on the eastern
shore by the Washington National Airport, and on the western shore opposite Theodore Roosevelt
Island (Figure 29; Appendix B: Maps 28, 34).
SAV beds persisted, but with large decreases, in Quantico, Neabsco, Pomonkey, Chicamuxen, and
Broad creeks; in the Occoquan River and Belmont Bay; in Gunston Cove and Accotink Bay; along
Mason Neck; and in one large bed above the 1-95 (Woodrow Wilson) bridge (Figure 29; Appendices
115
-------
SAV
B and D: Maps 34, 39, 40, 47, 48). The largest decreases occurred in Quantico, Neabsco, and
Chicamuxen creeks; in the Occoquan River and Belmont Bay; in Gunston Cove and Accotink Bay;
and around the perimeter of the large bed above the 1-95 bridge (Figure 29; Appendices B and D:
Maps 34, 39,47,48). Beds present in 1996 in the Washington Channel and in the Anacostia River
were decreased in 1997 (Figure 29; Appendices B and D: Maps 28, 29, 34).
The largest increases occurred in Belmont Bay; Broad and Pomonkey creeks; the shore by Dogue
Creek; the shore north of Pomonkey Creek to the 1-95 bridge; and the shore along Alexandria
(Appendices B and D: Maps 34, 39, 40).
In POTTF in 1997, ten species were reported as well as fourteen sightings of unidentified species of
Najas (Appendices B and D: Maps 28, 29, 34, 39, 40, 47, 48, 176).

Mattawoman Creek (MATTF)
SAV in MATTF increased 14% over 1996, to 50.28 hectares, 93% of the Tier I goal of 54.33
hectares (Figure 29; Tables 6 and 7; VIMS SAV CIS Database; CBP). The Tier I goal was last
exceeded in 1992; 1991 was the first and only other year it was exceeded (Figure 29; VIMS SAV
GIS Database; CBP).
In 1997, SAV density in MATTF increased: 94% was dense, 4% moderate, and 2% sparse, compared
to 79% dense in 1996, 8% sparse, and 13% very sparse (Figure 29; Table 8).
SAV beds persisted along both shores of Mattawoman Creek, with some areas of increase and some
areas of decrease in these beds. Noticeable decreases occurred at the mouth were beds disappeared
entirely from both shores. Significant increases were mapped in beds on both shores and especially
the bed at Thorofare Island (Appendices B and D: Map 48). New beds were mapped on both shores:
on the south shore at Bullock Neck; and on the north shore around Marsh Island; and on the shore
up to Indian Head (Appendices B and D: Map 48).
In MATTF in 1997, five species were reported: the USGS reported H. verticillata, V. americana,
N. minor, and C. demersum along the north shore of Mattawoman Creek, and H. verticillata, V.
americana, M. spicatum, and N. minor on the south shore, from the mouth to the vicinity of Indian
Head (Appendices B and D: Map 48). Upstream of Indian Head, Citizens reported H. verticillata,
V. americana, C. demersum, N. minor, and M. spicatum, including sightings from areas where no
SAV was mapped (Appendices B and D: Map 48).
Piscataway Creek (PISTF)
SAV in PISTF in 1997 increased 142% over 1996, to 123.25 hectares, 36% of the Tier I goal of
337.83 hectares (Figure 29; Tables 6 and 7; VIMS SAV GIS Database; CBP). There has been no
year in the history of the aerial survey in which the SAV level in PISTF exceeded the Tier I goal; in
1987 there were 319.35 hectares mapped, the highest level recorded by the survey (Figure 29; Tables
117
-------
SAV
6 and 7; VIMS SAV GIS Database; CBP).
In 1997 in PISTF, SAV density increased: 100% of the SAV was classified as dense, compared to
90% moderate in 1996, and 10% sparse (Figure 29; Table 8).
SAV beds persisted, with large increases, along both shores in PISTF in 1997, especially the large
bed at the head of the creek (Figure 29; Map 40). In these same beds a few small areas of decreases
were also mapped, especially at the mouth and the east end of the large bed at the head of the creek
(Figure 29; Map 40; Bed M4).
From the north shore, the USGS reported: V. americana, H. dubia, H. verticillata, C. demersum,
and N. minor; and from the south shore, H. verticillata, N. minor, and V. americana (Appendices
B and D: Map 40). Citizens reported H. verticillata from both shores, and C. demersum, H.
verticillata, and an unidentified species of Najas from the large bed at the head of the creek
(Appendices B and D: Map 40).
Lower Bay Zone
WESTERN LOWER CHESAPEAKE BAY AND ASSOCIATED TRIBUTARY AND BAY
SEGMENTS
Western Lower Chesapeake Bay (CB6PH)
In 1997 in CB6PH, SAV distribution decreased 9% from 1996, to 361.84 hectares, 4% of the Lower
Bay zone SAV total and 71 % of the Tier I goal of 511.84 hectares (Figure 30; Tables 6 and 7; VIMS
SAV GIS Database; CBP). In 1997, SAV in CB6PH decreased for the fourth consecutive year, from
the 1993 high point of 511.93 hectares, which exceeded the Tier I goal, to the lowest level since
1989, when 351.40 hectares were recorded (Figure 30; VIMS SAV GIS Database; CBP).
The percentage of SAV classified as dense increased in 1997 in CB6PH, however, the number of
hectares was actually less than in 1996: 62% (224.85 hectares) of SAV was classified as dense
compared to 58% (227.88 hectares) dense in 1996 (Figure 30; Table 8). Also in CB6PH, 11% was
moderate and 9% was sparse in 1997 compared to 12% moderate and 12% sparse in 1996 (Figure
30; Table 8). The percentage of SAV classified as very sparse was the same (18%) in both 1997 and
1996, however, the actual number of hectares of very sparse SAV in 1997 was less, 63.41 hectares
compared to 73.23 hectares in 1996 (Figure 30; Table 8).
Although SAV beds in CB6PH persisted in 1997, areas with decreases were mapped at: Windmill
Point on Fleets Island; Sandy Point by Gwynn Island; Winter and Horn harbors; Potato Neck; and
New Point Comfort (Figure 30; Appendices B and D: Maps 118, 123, 132). A few small areas of

increases were also mapped as well near some of the same localities (Windmill and Sandy points;
Winter and Horn harbors; Potato Neck; and New Point Comfort), however, these did not offset the
total of the decreases at these localities (Figure 30; Appendices B and D: Maps 118, 123, 132).
No ground-truth information was reported for CB6PH in 1997.
Eastern Lower Chesapeake Bay (CB7PH)
SAV in CB7PH in 1997 increased 3%, to 3,937.20 hectares, 81% of the Tier I goal of 4,888.75
hectares, 42% of the Lower Bay zone SAV total, and 14% of the Bay SAV total (Figure 30; Tables
6 and 7; VMS SAV GIS Database; CBP). SAV in CB7PH increased for the second consecutive
year in 1997, after decreasing for two years from the high point of 4,469.51 hectares in 1993 (Figure
30; Tables 6 and 7; VIMS SAV GIS Database).
In 1997 in CB7PH, SAV classified as dense, and that classified as very sparse, both increased: 38%
was dense in 1997 compared to 30% dense in 1996; and 33% was very sparse in 1997 compared to
22% very sparse in 1996 (Figure 30; Table 8). Also in 1997, SAV classified as moderate, and that
classified as sparse, both decreased: 9% was moderate compared to 19% moderate in 1996; 20% was
sparse compared to 28% sparse in 1996 (Figure 30; Table 8).
Large beds persisted at the mouths of creeks and inlets along the shore of CB7PH in 1997: at Savage,
Russell, Camp, Rogue, Tobacco, Parkers, and Finney islands; around Big, Parkers, and Hyslop
marshes; in Deep, Pompco, Chesconessex, Back, Nandua, Onancock, Matchotank, Pungoteague,
Curratuck, Craddock, Occohannock, Nassawadox, Pungers, Kings, Old Plantation, and Elliott creeks;
at Ware, Sparrow, Sandy, Battle, and Westcoat points; around Hacks, Scarborough, Occohannock,
Church, Old Town, and Savage necks; at Downings and Hungars beaches; at the mouth of Wester
house Creek; at Cape Charles, Cape Charles Harbor, and Cherrystone Inlet; at Pond Drain, The Gulf,
and White Cliffs; and in Fishermans Inlet and on the north shore of Fishermans Island in the mouth
of the Chesapeake Bay (Figure 30; Appendices B and D: Maps 108, 109, 113, 114, 119, 124, 133,
134, 142, 186). [In 1996, SAV was mapped for the first time in the aerial survey at Fishermans
Island (Figure 30; VIMS SAV GIS Database)]. There was no SAV mapped south of Pond Drain to
Wise Point on the southern end of the Delmarva Peninsula (FigureSO; Appendix B: Maps 142, 186).
New beds were most evident in the Pompco Creek and Tobacco Island area; in Onancock Creek;
around Finney Island; in Pungoteague, Nandua, Craddock, Occohannnock, Nassawadox, Pungers,
Mattawoman, and Old Plantation creeks; in Cherrystone Inlet; and at Fishermans Island and
Fishermans Inlet (Figure 30; Appendices B and D: Maps 109, 113, 114, 119, 124, 133, 142, 186).
The VIMS field survey, the Citizens, and the USFWS reported two species in CB7PH in 1997: Z.
marina and R. maritima (Appendices B and D: Maps 108, 114, 119, 124, 133, 134, 142). VMS

reported R. maritima in the area of Big Marsh, Rogue Island, and south of Rogue Island; Z. marina
and R. maritima around Russell Island; R. maritima to the east of Parkers Island; R. maritima off
Craddock Creek; R. maritima and Z. marina in Occohannnock Creek; R. maritima and Z. marina
in Hangars Creek; R. maritima and Z. marina in the area of Mattawoman Creek; R. maritima at the
mouth of the Cherrystone Channel; R. maritima to the south of White Cliffs; and Z. marina at the
mouth of Elliotts Creek (Appendices B and D: Maps 108, 114, 119, 124, 133, 134, 142).
The Citizens reported the following: R. maritima in Nassawadox Creek; Z. marina and R. maritima
in Mattawoman Creek; and Z. marina to the east of Hangars Beach and in Old Town Neck
(Appendices B and D: Map 124). The USFWS had reported Z. marina and R. maritima at the mouth
of Kings Creek at Cherrystone Inlet (Appendices B and D: Map 133).
RAPPAHANNOCK RIVER AND CORROTOMAN RIVER SEGMENTS
Lower Rappahannock River (RPPMH)
SAV in RPPMH in 1997 decreased 43% from 1996, to 14.70 hectares, 1.5% of the Tier I goal of
999.92 hectares (Figure 31; Tables 6 and 7; VIMS SAV GIS Database; CBP).
SAV density in 1997 in RPPMH increased: 34% was sparse and 66% very sparse, compared to 68%
sparse in 1996, and 32% very sparse (Figure 31; Table 8).
SAV beds persisted in RPPMH in 1997 on the northern shore of the Rappahannock River, with large
decreases, as well as some areas of slight increases, at Windmill Point, by Mosquito Island, in Sanders
Cove, and in Carter and Topps coves at the mouth of Carter Creek; and one bed which was present
at Mosquito Point in 1996 was not present in 1997 (Figure 31; VMS SAV GIS Database). No beds
were mapped on the south shore of the Rappahannock River in 1997, as in 1996 (Figure 31; VIMS
SAV GIS Database).
VIMS reported R. maritima and Z. palustris at the mouth of Carter Creek in 1997 (Appendices B
and D: Map 111, Bed HI).
Corrotoman River (CRRMH)
SAV in CRRMH in 1997 decreased 31 % from 1996, to 15.29 hectares, 7.0% of the Tier I Goal of
218.56 hectares (Figure 31; Tables 6 and 7; VIMS SAV GIS Database; CBP).
SAV density increased in 1997 in CRRMH: 68% was classified as moderate and 32% as sparse,
compared to 45% moderate in 1996, 50% sparse, and 5% very sparse (Figure 31; Table 8).
In the Eastern Branch in CRRMH in 1997, two SAV beds persisted with decreases, one SAV bed
(B3) was new, and one bed present in 1996 was not mapped (Figure 31; Appendix B: Map 111; Beds

A3, B3, C2). Beds present in 1996 in the Western Branch and in the area south of Corrotoman Point
were not mapped in 1997 (Figure 31; VMS SAV GIS Database). On the western shore of CRRMH,
SAV beds persisted, with areas of slight increases as well as areas of decreases, at the mouth of
Myers Creek (Figure 31; Appendix B: Map 111).
In CRRMH in 1997, VIMS reported R. maritima from the bed east of Queenstown at the mouth of
Myers Creek (Appendices B and D: Map 111, Bed F3).
Middle Rappahannock River (RPPOH) and Upper Rappahannock River (RPPTF)
The Middle Rappahannock River (RPPOH) and the Upper Rappahannock River (RPPTF) both had
no SAV mapped in 1997 or in any year since the aerial survey began (Figure 31; Tables 6 and 7;
VIMS SAV GIS Database). There have been no Tier I goals established for RPPOH and RPPTF
(Figure 31; VMS SAV GIS Database; CBP).
No ground-truth data was reported for RPPOH and RPPTF in 1997.
Piankatank River (PIAMH)
SAV in PIAMH in 1997 increased 23% over 1996, to 175.01 hectares, 22% of the Tier I Goal of
806.85 hectares, 2% of the SAV total for the Lower Bay zone, and 0.62% of the Bay SAV total
(Figure 32; Tables 6 and 7; VMS SAV GIS Database; CBP).
SAV density increased in 1997 in PIAMH: 21% was classified as dense, 21% as moderate, 41% as
sparse, and 17% as very sparse, compared to 10% dense in 1996,3% moderate, 86% sparse, and 1%
very sparse (Figure 32; Table 8).
In 1997 in PIAMH, the two SAV beds on the north shore of the Piankatank River persisted, but with
large decreases, and the bed mapped in 1996 on the south shore was not mapped in 1997 (Figure 32;
VMS SAV GIS Database). Beds also persisted around Gwynn Island and The Hole In The Wall,
with large increases and with some small areas of decreases (Figure 32).
In 1997, VMS reported Z. marina in the bed at Cherry Point at the north end of Gwynn Island, and
Z. marina and R. maritima in the area of Milford Haven on the south end of Gwynn Island
(Appendices B and D: Maps 118, 123).
Mobjack Bay (MOBPH)
SAV in 1997 in MOBPH increased 3% over 1996, to 4,442.49 hectares, 80% of the Tier I goal of
5,561.71 hectares, 47% of the Lower Bay zone SAV total, and 16% of the Bay SAV total (Figure
33; Tables 6 and 7; VMS SAV GIS Database; CBP). MOBPH has continued to have the largest
amount of SAV in the Lower Bay zone throughout the history of the aerial survey (Figure 33;

SAV density decreased in 1997 in MOBPH: 65% was classified as dense, 12% as moderate, 16% as
sparse, and 7% as very sparse, compared to 72% dense in 1996, 9% moderate, 14% sparse, and 4%
very sparse (Figure 33; Table 8).
MOBPH continued in 1997 to have some of the more extensive SAV beds on the western shore of
the lower Chesapeake Bay: extending along the entire shoreline of Mobjack Bay; including the
Guinea Marshes at the mouth of the York River; as well as the lower reaches of the Severn, Ware,
North, East, York, Back, and Poquoson rivers; and including the Poquoson and Drum Island flats
(Figure 33; Appendix B: Maps 122, 123, 131, 132, 140, 141, 147).
SAV beds persisted on all shores and tributaries in MOBPH in 1997, with areas of increases and areas
of decreases (Figure 33; Tables 6 and 7; Appendices B and D: Maps 122, 123, 131, 132, 140, 141,
147). SAV beds persisted from the North River to Northend Point, with areas of increases and areas
of decreases (Figure 33; Tables 6 and 7; Appendices B and D: Maps 122, 131, 140, 141, and 147).
Increases were noted in the North, Ware, Severn, York, Poquoson, and Back rivers; in Ware Neck,
Four Point Marsh, and the Guinea Marshes; at Goodwin and Cow islands; at Tue, Bay Tree, Ship,
Marsh, and Drum points; and at Poquoson and Drum Island flats (Figure 33; Tables 6 and 7;
Appendices B and D: Maps 122, 131, 132, 140, 141, 147).
The largest decreases were noted at Horse Point, Ware Neck, and the Ware River; and smaller areas
of decrease were mapped in Four Point Marsh and the mouth of the Northwest Branch in the Severn
River, in Guinea Marshes and Sandy Point in the York River, at Goodwin Islands and the bed in the
area of Tue Point, at Cow Island, in the Poquoson River (with one bed absent in 1997 which had been
present in 1996), at Drum Point and Drum Island Flats, and in Back River (Figure 33; Appendices
B and D: Maps 122, 131, 140, 141, 147).
SAV beds also persisted from Backwater Creek to New Point Comfort, with small areas of increase
as well as some small areas of decrease (Figure 33; Appendices B and D: Maps 122, 123, 131, 132).
Decreases occurred in the area west of Cakes and Goosey creeks; small areas of decrease occurred
in the East River, in Pepper Creek, and around the tip of New Point Comfort (Figure 33; Appendices
B and D: Maps 122, 123, 132). Increases occurred in the area south of Backwater Creek; at the
mouth of Cakes Creek; in Goosey Creek; in East River; in the area of Sharp Point and Weston and
Tab. creeks where new SAV beds were mapped; in Pepper Creek, at the mouth of Davis Creek, and
the area south of Davis Creek to New Point Comfort (Figure 33; Appendices B and D: Maps 122,
123, 132).
Ruppia maritima and Z. marina were reported by the VIMS Field Survey and the Citizens' survey
from MOBPH in 1997 (Appendices B and D: Maps 131, 132, 140, 141, 147). VJMS researchers

R. maritima and Z. marina in the Guinea Marshes; Z. marina and /?. maritima in the area surrounding
the Goodwin Islands; /?. maritima in the area of Drum Point; and Z. marina in the Back River
(Appendices B andD: Maps 131, 132, 140, 141, 147).
The Citizens' reports were as follows: R. maritima on both shores of the East River; R. maritima and
Z. marina in Pepper and Harper creeks, at New Point Comfort, and along the eastern shore of
Mobjack Bay (Appendices B and D; Map 132).
YORK RIVER AND TRIBUTARY SEGMENTS
Lower York River (YRKPH) and Middle York River (YRKMH)
In the York River in 1997, there was a slight increase of SAV reported from YRKPH, the only York
River CBP segment to have had any SAV throughout the history of the aerial survey (Figure 34;
Tables 6 and 7; VMS SAV CIS Database; CBP).
Lower York River (YRKPH)
SAV in 1997 in YRKPH increased 11% over 1996, to 339.50 hectares, 4% of the Lower Bay zone
SAV total, 1 % of the Bay SAV total, and 60% of the Tier I goal of 566.98 (Figure 34; Tables 6 and
7; VMS SAV CIS Database; CBP).
In 1997 in YRKPH, 86% of SAV was classified as dense, 6% as sparse, and 8% as very sparse,
compared to 80% classified dense in 1996,4% moderate, 12% sparse, and 4% very sparse (Figure
34; Table 8).
In 1997 in YRKPH, SAV persisted on the south shore of the York River, downstream from the
Coleman Bridge at Yorktown, to Worsley Creek, and at the end of Goodwin Neck near Goodwin
Island; and immediately upstream from the bridge, two small beds were mapped (Figure 34; Appendix
B: Maps 139, 140; VMS SAV GIS Database). Along the north shore, beds persisted downstream
from the Coleman Bridge at Gloucester Point, to the mouth of the York River; and immediately
upstream of the bridge, one small bed was mapped (Figure 34; Appendix B: Maps 130, 131, 139,
140; VMS SAV GIS Database). Significant increases of SAV occurred in the areas of Aliens Island
and Sandy Point on the north shore (Figure 34; Appendix B: Map 131; VMS SAV GIS Database).
Increases also occurred on the southern shore of the York River, along the Yorktown area, and at
the mouth of the Thorofare by Goodwin Neck (Figure 34; Appendix B: Maps 139,140; VMS SAV
GIS Database). Decreases to beds were mapped along both shores: on the north shore, at Gloucester
andGaines points; and on the south shore, along Yorktown (Figure 34; Appendix B: Maps 130,131,
139, 140; VMS SAV GIS Database).

1997
In 1997 in CB8PH, 82% of SAV was classified as sparse, and 18% as very sparse, compared to 86%
sparse in 1996, and 14% very sparse (Figure 35; Table 8).
In 1997 as in 1996, SAV was again mapped only in an inlet of the southern shore of CB8PH and not
along the main stem Chesapeake Bay (Figure 35: Map 151; VIMS SAV GIS Database). SAV
persisted in 1997 in two beds, one in the Little Creek Channel, and another in Little Creek Cove, for
the third consecutive year in the history of the aerial survey (Figure 35: Map 151; VIMS SAV GIS
Database; Orth et al, 1996, 1997). [(Re-examination of previous years aerial photography has
revealed the SAV signature, which apparently went undetected prior to 1995 primarily because of
its isolated location (VIMS SAV GIS Database).]
VIMS found two species in CB8PH in 1997: Z. marina was noted in the bed mapped in Little Creek
Channel; R. maritima and Z. marina was noted in the bed mapped in Little Creek Cove (Appendices
B and D: Maps 151, 152).
Lynnhaven and Broad Bays (LYNPH)
SAV in 1997 in LYNPH decreased 47% from 1996, to 16.14 hectares, 23% of the Tier I goal of
71.18 hectares (Figure 35; Tables 6 and 7; VIMS SAV GIS Database; CBP).
In 1997 in LYNPH, 6% of SAV was classified as moderate, 8% as sparse, and 86% as very sparse,
compared to 19% moderate in 1996, 50% sparse, and 30% very sparse (Figure 35; Table 8).
SAV beds persisted in LYNPH in 1997 with considerable decreases, and a few areas of small
increases, in Broad Bay and adjacent Linkhorn Bay, as in 1996: in Broad Bay, SAV beds were
mapped on both the north and the south shores; in Linkhorn Bay there was only one bed mapped, on
the north shore (Figure 35; Appendix B: Map 152; VMS SAV GIS Database).
The Citizens reported several sightings of unidentified species of SAV on both shores of Broad Bay
and on the north shore of Linkhorn Bay; VIMS had one sighting of Z. marina on the north shore of
Broad Bay (Appendices B and D: Map 152).
JAMES RIVER SEGMENTS AND ASSOCIATED TRIBUTARY SEGMENTS
Mouth of James River (JMSPH), Lower James River (JMSMH), Middle James River
(JMSOH), and Upper James River (JMSTF)
The Upper James (JMSTF) and the Middle James (JMSOH) had no SAV mapped in 1997, but SAV
abundance in the Lower James River (JMSMH) and the Mouth of the James River (JMSPH)
increased in 1997 from that in 1996 (Figures 36 and 37; Tables 6 and 7). No SAV was mapped in
1997 in the James River tributary segments (Figures 36 and 37; Tables 6 and 7).

SAV
Mouth of James River (JMSPH)
SAV in JMSPH in 1997 increased 303% over 1996, to 75.74 hectares, 0.81 % of the Lower Bay zone
SAV total, and 477% of the Tier I goal of 15.89 hectares (Figure 36; Tables 6 and 7; VIMS SAV
GIS Database; CBP).
In 1997 in JMSPH, 12% of the SAV was classified as dense, 1% as moderate, 3% as sparse, and 85%
as very sparse, compared to 33% dense in 1996, and 67% very sparse (Figure 36; Table 8).
SAV beds persisted with significant increases from Newport News Point, east to the Hampton Roads
Bridge tunnel (Figure 36; Appendices B and D: Maps 147, 149). The bed between Newport News
Point and Salters Creek increased greatly in 1997, and a new bed was mapped east of Salters
Creek(Figure 36; Appendices B and D: Map 149). In 1996, in this area, small patches of SAV up
to approximately two meters squared, consisting of Z. marina, were recorded between Newport
News Point and Salters Creek; these patches were estimated to be 2-3 years old, but were not noted
in earlier aerial surveys because their small size prohibited detection by the aerial photography (VIMS
SAV GIS Database).
Since the baywide survey began in 1978, and until 1995, only one bed had been mapped in the main
stem of the James River, at the mouth of Hampton River (VIMS SAV GIS Database; Orth et
al, 1996). This bed persisted and increased to four beds by 1996; and a fifth bed was mapped east
of the Hampton Bridge in 1997 (Figure 36; VIMS SAV GIS Database; Orth etai, \ 997). [Small plots
of Z. marina were transplanted in this area in the fall of 1994, in the locations of 1997 beds Ul and
Rl, and off the Hampton River in 1996 and by the Monitor-Merrimac bridge in 1997, as part of the
VIMS seagrass restoration program, which is funded by the Virginia Saltwater Recreational License
Fund (VIMS SAV GIS Database; Appendices B and D: Map 147).]
In JMSPH in 1997, the VIMS Survey had several reports of Z. marina along the Hampton Flats and
at the mouth of the Hampton River (Appendices B and D: Maps 147. 149).
ELIZABETH RIVER AND TRIBUTARY SEGMENTS
Lower Elizabeth River (ELIPH) and Lafayette River (LAFMH)
No SAV was mapped in either ELIPH or LAFMH in 1997, as in 1996 (Figure 36; Tables 6 and 7;

WBEMH, SBEMH, and EBEMH (Figure 36; VIMS SAV CIS Database; CBP).
No ground-truth information was reported for ELIMH, WBEMH, SBEMH, or EBEMH in 1997.
Lower James River (JMSMH)
InJMSMHin 1997, where no SAV was present in 1996, 1.05 hectares SAV were mapped in one bed
on the northern shore of the Lower James River (Figure 36; Tables 6 and 7; VIMS SAV GIS
Database). This figure represent 0.01 % of the Lower Bay zone SAV total (Figure 36; Tables 6 and
7; VIMS SAV GIS Database). No Tier I goal has been established for JMSMH (Figure 36; CBP).
All the SAV in 1997 was classified as sparse (Figure 36; Table 8).
There was one VIMS report for Z. marina in the bed mapped for the James River in 1997
(Appendices B and D: Map 149; Bed A2).
Middle James River (JMSOH) and Chickahominy River (CHKOH)
No SAV was mapped in either JMSOH or CHKOH in 1997, as in 1996 (Figure 37; Tables 6 and 7;
VIMS SAV GIS Database). No Tier I goal has been established for JMSOH, however, the Tier I
goal for CHKOH is 91.28 hectares (Figure 37; VIMS SAV GIS Database; CBP). CHKOH did have
SAV reported in 1986 (13.91 hectares) and 1978 (89.17 hectares) (Figure 37; VIMS SAV GIS
Database).
No ground-truth information was reported for either JMSOH or CHKOH in 1997.
Upper James River (JMSTF) and Appomattox River (APPTF)
No SAV was mapped in either JMSTF or APPTF in 1997, as in 1996 (Figure 37; Tables 6 and 7;

SAV
PENINSULA COASTAL BAYS ZONE (The Delmarva Barrier Island Bays)
The Delmarva Peninsula Coastal Bays zone was reconfigured in 1997 to exclude Fishermans Island
at the mouth of the Chesapeake Bay; it includes the following Delmarva barrier island bays:
Chincoteague, Sinepuxent, Assawoman, Isle of Wight, and Magothy bays (Figure 38; Methods:
Figure 9). There were 5,598.37 hectares of SAV mapped in 1997 in the Delmarva Peninsula Coastal
Bays zone, compared to 4,556.09 hectares in 1996 (excluding Fishermans Island), an increase of
1,042.27 hectares or 23% (Figure 38; Tables 6 and 7; VIMS SAV CIS Database). There is no Tier
I goal for this zone.
In 1997, SAV increased in each of the component bays of this zone which had SAV in 1996 (Figure
38; VIMS SAV GIS Database). The total hectares for the component bays of this zone in 1997 and
1996 are: Chincoteague Bay, 4,916.78 hectares in 1997, compared to 3,987.86 hectares in 1996;
Sinepuxent Bay, 421.40 hectares in 1997, compared to 343.73 hectares in 1996; Assawoman Bay,
180.32 hectares in 1997, compared to 178.16 hectares in 1996; and Isle of Wight Bay, 79.98 hectares
in 1997, compared to 46.34 hectares in 1996 (VIMS SAV GIS Database). Magothy Bay had no
SAV mapped from aerial photography in 1997 or in 1996, however, VIMS and the Virginia Marine
Resources Commission (VMRC) transplanted Z. marina to sites in Magothy Bay in 1996 and 1997
(VIMS SAV GIS Database).
Despite the increases in SAV mapped in 1997, significant damage to many SAV beds occurred in
1997 from clam dredging activities in both Virginia and Maryland, resulting in many beds having
lower density rankings. The level of destruction was noted in reports to the Virginia Marine
Resources Commission (VMRC) (Moore and Orth, 1997) and to the MD-DNR (correspondence to
the Secretary of MD-DNR). Consequently, protection was afforded to SAV beds by the creation of
a SAV sanctuary in Virginia's Chincoteague Bay, and by legislation in Maryland which prohibits
hydraulic dredging in existing SAV beds.
In the Delmarva Coastal Bays zone in 1997, the percentage of SAV classified as dense (62%)
remained the same as in 1996 (62%), however, in terms of the absolute number of hectares, in 1997
there were 665.78 hectares more in Density Class 4 than in 1996 (Table 9). The percentage, as well
as the absolute number, of hectares of SAV classified as moderate in 1997 decreased: 4% (217.93
hectares) was classified as moderate in 1997, compared to 12% (565.28 hectares) in 1996 (Table 9).
The percentage of SAV in combined Density Classes 3 and 4 decreased in 1997, but the absolute
number of hectares increased 318.43 hectares over that in 1996: combined Density Classes 3 and 4
constituted 66% (3,685.80 hectares) of the SAV in 1997, compared to 74% (3,367.37 hectares) in
1996 (Table 9). The percentages of sparse and very sparse SAV both increased in 1997, as well as
the absolute number of hectares for these categories: 26% (1,447.66 hectares) was sparse in 1997,
compared to 22% (991.03 hectares) in 1996; and 8% (464.91 hectares) was very sparse in 1997,
compared to 4% (197.70 hectares) in 1996 (Table 9). SAV in combined Density Classes 1 and 2
increased in 1997, constituting 34% (1,912.57 hectares) of the SAV in 1997, compared to 26%
(1,188.73 hectares) in 1996 (Table 9).

SAV
As in 1996, SAV in ChincoteagueandSinepuxent bays was located primarily along the eastern sides
of both bays, however, a few beds were mapped for the second consecutive year on the western
shores of both ChincoteagueandSinepuxent bays (Figure 38; Appendix B: Maps 166, 167, 168, 170,
171, 172, 173, 174, 175; VIMS SAV GIS Database). SAV beds persisted on the western side of
Chincoteague Bay at Horntown Landing, Cockle Point, and the mouth of Powell Creek, with new
beds mapped in Hawthorne Bay, Egg Marsh, Wire Narrows Marsh, and Mills and Assacorkin islands
(Figure 38; Appendix B: Maps 171, 172, 174; VIMS SAV GIS Database). On the eastern side of
Chincoteague Bay, SAV beds persisted and increased in the Coards Marshes area, Great Neck/Toby
Island area, the West Bay area, Green Run Bay, Whittington Point, Scotts Point, Fox Hill Point,
Sugar Point, Tingles Island area, and Newport Bay along lower Sinepuxent Neck (Figure 38;
Appendix B: Maps 170, 172, 173, 174, 175; VIMS SAV GIS Database). On the eastern side of
Chincoteague Bay, new beds were mapped at the mouth of Chincoteague Channel (Figure 38;
Appendix B: Map 174; VIMS SAV GIS Database).
In Sinepuxent Bay, beds persisted with increases on both shores in the same areas as 1996 (Figure
38; Appendix B: Maps 167, 168, 170; VIMS SAV GIS Database). Increases to beds were especially
noticeable at South, Goose, Rum, Fassett, and Sandy points; by the Route 61 1 Bridge; and in Sandy
Cove (Figure 38; Appendix B: Maps 167, 168, 170; VIMS SAV GIS Database). The bed mapped
by the Ocean City Airport in 1996 was not mapped in 1997 (Figure 38; Appendix B: Map 168; VIMS
SAV GIS Database).
In Isle of Wight and Assawoman bays, beds persisted on the eastern shore along Ocean City (Figure
38; Appendices Band D: Maps 166, 168; VIMS SAV GIS Database). In Isle of Wight Bay, the large
bed south of Ocean City Expressway increased significantly, and in Assawoman Bay increases were
mapped at Swan Point and Devil Island (Figure 38; Appendices B and D: Maps 166, 168; VIMS
SAV GIS Database).
The Citizens' survey (including the Ocean Pines Yacht Club survey), the National Park Service, and
VIMS reported two species, Z. marina and R. maritima, from the coastal bays in 1997 (Appendices
B andD: Maps 143, 166, 167, 168, 170, 171, 172, 174, 175).
Citizens reported R. maritima along the eastern shores of Assawoman and Isle of Wight bays; Z.
marina in Assateague Bay by Cherrytree Hill and on Vineyard Shoal; and R. maritima andZ. marina
in Coards Marshes (Appendices B and D: .Maps 166, 175).
The National Park Service reported the following species: R. maritima above Sandy Point in
Sinepuxent Bay; R. maritima and Z. marina in Sinepuxent Bay around Sandy Point Island; R.
maritima and Z. marina south of Tingles Island off Assateague Island on the eastern shore of
Chincoteague Bay; Z. marina in Pope Island Ditch and West Bay off Assateague Island; Z. marina
and R. maririma in and around Coards Marshes; Z. marina between Ragged and Wildcat points on
the eastern shore of Chincoteague Bay; and Z. marina and R. maritima in Spence Cove off the west
side of lower Sinepuxent Neck (Appendices B andD: Maps 167, 168, 170, 172, 175). The NPS also

reported Z. marina at Cockle Point on the western shore of Chincoteague Bay (Appendices B and
D:Map 174).
The VIMS survey reported Z. marina from the western shore of Chincoteague Bay: at the mouth of
Powell Creek, in Horntown Bay, at Egg Marsh, at Wire Narrows Marsh, at Cockle Point, and at Mills
and Assacorkin islands; and, from the eastern shore of Chincoteague Bay, R. maritime/. andZ. marina
in the Coards Marshes area (Appendices B and D: Maps 171, 172, 174, 175). VIMS reported R.
maritima and Z. marina on the eastern shore of Assawoman and Isle of Wight bays (Appendices B
and D: Map 166). VIMS also reported Z. marina at Skidmore Island in Magothy Bay, which was
one of the VIMS transplant sites (Appendices B and D: Map 143).
