Introduction

Annex 3 of the 1978 Great Lakes Water Quality Agreement and its Supplement
requires that both the United States and Canada confirm future phosphorus
loads and establish load allocations and compliance schedules for meeting
those loads.  The Annex 3 Supplement establishes phosphorus target loads and
load reductions for the Lower Lakes, Lakes Erie and Ontario, and Saginaw Bay.
In order to provide the Great Lakes States with a basis for state and
river basin load planning, it is necessary to have an estimate of the loading
from each tributary and the amount of potential load reduction.  For this
report it was agreed that the 1982 water year would be used as a base year
for Lakes Erie and Ontario and the 1980 water year for Saginaw Bay.

This report summarizes total phosphorus loads for water year 1982 by major
river basins and includes municipal and industrial point sources as  well as
nonpoint sources.  The intent of this report is to partition the known phosphorus
load to the Lower Lakes  into its tributary origins and point/nonpoint compon-
ents.  The report and any conclusions derived from it are totally dependent
on the reliability and accuracy of the phosphorus load data bases.  Some of
the tributary load values are estimated since neither flow nor concentration
data is routinely collected on a regular basis.  Unmonitored tributaries are
listed for Lakes Erie and Ontario.  Point source data is reported by each
discharger as required by the NPDES permit system for both monitored and
unrnonitored tributaries.  Overall there does appear to be satisfactory corre-
lations between lake phosphorus concentrations and reported loadings.

Figures 1, 2, and 3 summarize phosphorus loads for Lake Erie, Lake Ontario and
Saginaw Bay, respectively.  Total hydrologic drainage area loads and basin
loads including all components are provided.  Excess municipal loads, which are
those loads above or below a 1.0 mg/1 effluent phosphorus concentration, are
given.  A negative excess load means that a single or group of municipal
facilities are collectively discharging effluent with a phosphorus concentration
below 1.0 mg/1.  A positive excess load means that the facilities are
discharging an effluent with a phosphorus concentration above 1.0 mg/1.  This
positive excess load is that amount of phosphorus which is expected  to be
reduced when the facilities comes into compliance with the 1.0 mg/1  effluent
phosphorus requirement.

Methodology

The study period for this report is water year 1982 (October 1981 -  September
1982).  This year was chosen because it is the most recent year for  which
complete and accurate tributary phosphorus data and point source data is
available.  Based on U.S. Geological Survey (USGS) Great Lakes tributary flow
data, (water resources data-Michigan, Ohio, Indiana, New York, Pennsylvania,
1982) water year 1982 in general appears to be representative of average or
near normal stream flow conditions in the lower lakes Basin.  Exceptional
rainfall events in any specific tributary may have occurred during the water
year.  Reported phosphorus loads from tributaries with exceptionally high or
low flow events should be carefully evaluated by the reviewer.

Lakes Erie and Ontario and Saginaw Bay drainage basins were subdivided into
hydrologic areas (complexes and river basins) following the procedures used in
the U.S. Task D reports on Great Lakes Pollution From Land Use Activities by
the international Joint Commission.  River Basin group maps and a brief
narrative description of each hydrologic area is included as Appendix 1

-------
                                     -2-
Municipal and industrial point sources were divided into direct and indirect
discharges for each major drainage basin to avoid double counting of phosphorus
loads.  Direct discharges are defined as a point source of phosphorus below
the tributary monitoring station or having an outfall  discharging into the
lake proper.  Indirect discharges are defined as a point source above the
tributary monitoring station so that the tributary load calculated at the
monitoring station includes those point sources. All  known point sources of
phosphorus for each drainage basin are listed in Appendix 2.

The 1982 phosphorus load for each hydrologic area was  calculated by adding
the tributary component and direct municipal and industrial point sources.
The nonpoint component of each hydrologic area phosphorus load was calculated
by subtracting the indirect municipal and industrial  point source loads from
the tributary load. (See figures 1, 2 and 3 for examples) The assumption for
these calculations is that the tributary load accounts for all sources of
phosphorus within the drainage basin including indirect point sources, non
point, and natural background.

Sources of Data

Tributary phosphorus load data was obtained from Dr.  John Clark, International
Joint Commission (IJC) Windsor, Ontario Regional Office.  Dr. Clark prepares
annual phosphorus tributary loading summaries for each of the Great Lakes as
secretariat to the IJC Water Quality Board's Surveillance Workgroup.
Tributary flow data from USGS gaged streams and phosphorus concentration
data from USGS, USEPA and State monitoring stations is used to calculate
tributary loads.  When tributary sampling is conducted on varying frequencies
(i.e. monthly grab, 24 composite etc.) during the water year, a stratum or
grouping of data is established for each distinctive  sampling frequency.  Daily
grab samples for example are not averaged with 24 hour flow weighted samples.
Each sample frequency is treated as a distinct data set.  The reference for
the methodology used is discussed in Sampling Techniques by William Cochran,
3rd Edition John Wiley & Son.

Phosphorus loads are estimated for unmonitored tributaries by using a unit
area ratio of an adjoining monitored tributary less its point sources.
Appendix 3 lists for Lakes Erie and Ontario those tributaries which are
monitored and unmonitored in addition to phosphorus loads in metric tons/year.
1980 tributary load data was used for Saginaw Bay since it was the only year
for which complete monitoring data is available for all rivers in the basin.

Point source load data for phosphorus is reported by  each of the Great Lakes
States for all major and significant municipal and industrial dischargers.
The State Pollution Control Agencies receive their data from each of the
NPDES permitted dischargers on a monthly basis.  The  data is then collected and
summarized by USEPA annually for transmittal to the International Joint Commission,

Summary

Figure 4 summarizes the total phosphorus load to Lake Erie,  Lake Ontario and
Saginaw Bay.  Each of the components of the total  load,  tributary,  point and
non-point, are quantified.  Based on the assumption  that water year 1982 was
generally representative of stream flow conditions in the Lower  Lakes  and
Saginaw Bay, these loads should provide a perspective of the tributary origins
and source magnitude of phosphorus.  The total  load  and  its  components are
quantities of total phosphorus actually delivered  to the Lakes  in 1982.  The
delivered load has not been adjusted nor corrected to reflect long  term
conditions or averages.

      The Black River encompasses an area of 180,000 hectares (446,000 acres).  In the
      central portion of Michigan's Lower Peninsula the Black River has a mean annual
 Hlrharee of 7.8 m3's (275 cfs).  An important tributary to the Black River is
 Mill Creek   The area is generally flat and has a significant amount of wetlands.
.Approximately 20 percent of area exists as scattered forested areas  about 60
 percent is (utilized in agriculture, and 10 percent is urbanized.  The bedrock
 consists primarily of sandstone.  The material covering the bedrock is composed
 of  silt and clay near the shore and glacial till throughout the rest of the b.asin.
 Important gas fields and salt  formations exist in the area   Approximately three
 najor municipalities and four  major industries use the surface waters of  this area
 Tor waste assimilation.  The cities of Port Huron  (pop.: 35,794), and Marysville
  (pop.:  5,610) are  the major population centers in the area.

      The St. Clair Complex includes 155,000 hectares (383,000 acres) in the
 southeast portion of Michigan's Lower  Peninsula.  The major rivers draining
 the area are the Pine River (ungaged), and the Belle River, which has a mean
 annual discharge of 2.3 m 's (81 cfs).  Both of these rivers drain into the
*St. Clair R4.ver.  There are a number of other small streams that also provide drainag<
 for this complex.  This area is generally flat with few wetlands.  Approximately
 15 percent of the area is forested, 60 percent devoted to agriculture, and 15
 percent urbanized.  The bedrock is composed principly of sandstone.  The overlying
 material is composed of silt,  clay and glacial till.  Several municipalities and
 industries use the area's rivers for waste assimulation.  The cities of
 St. Clair (pop.: 4,770), Marine City (pop.: 4,567), New Baltimore (pop.: 4,142),
 and Richmond (pop.: 3,234) are the areas of greatest human pressure on the Complex.

                                    Clinton River


      The Clinton River  drains  an area  of  155,000  hectares  (383,000  acres).  The
 area is located in the  southeast portion  of  Lake  Michigan's  Lower Peninsula.  The
 Clinton River has a mean annual  discharge of 14.3 m^'s  (505  cfs) and  drains
*into Lake S^. Clair.  Major  tributaries to the  Clinton  River are the  North
 Branch, Paint Creek,  and Red Run.   There  are several additional small streams that
 also provide drainage for the  area.  The  topography varies from flat  to  rolling
 with few wetlands.   About 15 percent of the  area  is forested,  50 percent
 agriculturalized, and 20 percent found in highly  developed metropolitan  areas.
 The bedrock is composed primarily of sandstone.   The surface material consists
 of  silt, clay and glacial till.   Heavy industrial development, to a large extent
 associated with the automotive industry,  is  a major influence on the  water
 quality of this area.   A considerable  amount of the area's municiple  waste
 is  treated by Detroit Water  Services and  discharged to  the Rouge River in
 Hydrologic Area 4.1.4.   However, there still is significant  municiple and
 industrial discharge into the  surface  waters.   The  Clinton River is characteris-
 tically sluggish (as many of the streams  draining into  the western  portion of
 Lake Erie) and carries  a high  silt load.   Cities  of Pontiac  (pop.:  85,279),
 Mt. Clements (pop.: 20,476), and Rochester (pop.: 7,054) are the major
 concentrated population centers  in the area.

                                       Rouge Complex
       The Rouge Complex encompasses an area of 189,000 hectares (468,00 acres).
  The Complex is located in the southeast portion of  Michigan's Lower Peninsula.
  The major tributary in the area is the Rouge River, which has a mean annual
  discharge of approximately 6.4 m  s (226 cfs).   Major tributaries to the Rouge
^ River are the Upper, Middle, and Lower Rouge Rivers.  The area is generally
  flat with few wetlands. Approximately 15 percent of the area is forested,
  another 20 percent devoted to agriculture, and over 50 percent consists of the
  highly developed Detroit Metropolitan Area.  Bedrock is composed of sandstone
  and shale.  The overlying material consists of silt and clay with some
  glacial till.  Heavy industry, to a large extent associated  with the automobile
  industry, effects the water quality of this Complex.  There  is some peat,
  clay, salt, and sand and gravel extracted from the  area.  A  large number of
  major industries and numerous combined sewer overflows discharge wastewater
  into the surface waters of this Complex.  The Rouge River drains much of metro-
  poliaton Detroit (approximate population 3,000,000), subjecting the river
  to severe human pressure.

                                    Huron River
     The Huron River drains an area of 220,000 hectares (543,000 acres).  The
area is located in the southeast portion of Michigan's Lower Peninsula.  The Huron
River has a mean annual discharge of 12.6 m^/s (445 cfs).   Major tributaries to
the Huron River are Mill Creek, and the Portage River.  Topography varies from
flat to rolling with relatively few wetlands.  Approximately 20 percent of the
area is  forested, 60 percent devoted to agriculture and 15 percent urbanized.
Bedrock is composed mostly of sandstone with some shale in the eastern portion.
The overlying material is composed principally of silt and clay in the east
with glacial till in the west.  Several municipalities and industries discharge
significant amounts of treated wastewaters into the surface waters of this area.
The cities of Ann Arbor (pop.: 99,797), Ypsilanti (pop.: 29,538), and Flat
Rock (pop.: 5,643) are the major developed and industrialized regions within
this area.

                                     Maumee River


     The Maumee River, the largest tributary to the Great Lakes, drains an area
of approximately 1,711,000 hectares (A, 229,000 acres).  Seventy-three and six
tenths percent of the area is located in northwest Ohio, with 19.4 percent in adjoining
Indiana and the remaining 7 percent in Michigan.  The Maumee River has a mean annual
discharge of 134.7 m  s (4,756 cfs).  The lower reaches of the Maumee are subject
to esturine effects.  The major tributaries to the Maumee are the St. Joseph River,
the Auglaize River, the St. Mary's River, and the Tiffin River.  Much of the land is
nearly level or gently sloping.  The fine textured glacial tills and lakelaid
clays have poor natural drainage.  The soils have slow permeability, and are
subject to intensive row cropping.  A glacial depression, formerly known as the
Great Black Swamp, covers a large portion of the basin.  Because the region is
poorly drained, drainage ditches and subsurface tile drains have been constructed
to remove water from much of the agricultural land.  Approximately 85 percent
of the area within the hydrologic boundaries is used for agricultural purposes.
Eleven percent of the area is found in urbanized areas with nearly 70 percent of the
population located in the three major areas of Fort Wayne, Indiana, Lima, Ohio,
and Toledo, Ohio.  Another 8 percent of the area can be classified as forest and
woodland.  The bedrock consists mostly of sandstone in the northwest section of the
area and dolomite in the southeast.  Bands of shale are interspersed throughout the
area.  The economy is based on manufacturing and agriculture with some extraction
of natural resources such as sand, gravel, limestone, dolomite and clay.
The heavy sediment load and its associated contaminants of the Maumee River is
a major source of pollution to Maumee Bay and Lake Erie in general.  The surface
waters of the area receive a heavy point source load of wastewater.  More than
150 municipalities, industries, and private wastewater sources use these surface
waters for waste assimiliation.  Important municipal and industrial centers in the
area are the cities of Fort Wayne, Indiana (pop.: 177,671), Toledo, Ohio (pop.:
383,818), Lima, Ohio  (pop.: 53,734), Findlay, Ohio (pop.: 35,800), Van Wert,
Ohio  (pop.: 29,194), Defiance, Ohio (pop.: 16,281), and Maumee, Ohio (pop.: 15,937).

                                 Toussaint-Portage Complex

     The Toussaint-Portage Complex covers 266,000 hectares (656,000 acres).   The area
is located in northwestern Ohio.  The major rivers in the area are the Portage River,
which has a mean annual discharge of 8.6 m^/s (304 cfs) and Toussaint Creek (ungaged).
A number of other small streams drain the remaining area.  The Complex is flat with fe
wetlands although the area is highly underdrained and ditched.  Less than 10
percent of the area is forested, approximately 80 percent is devoted to agriculture,
and about 10 percent is urbanized.  The bedrock is composed primarily of dolomite.
The overlying material is predominantly a mixture of silt and clay near the shore and
glacial till throughout the remainder of the complex.  Streams in this area are
usually high in dissolved solids.  The cities of Bowling Green (pop.: 21,760),
Fostoria (pop.: 16,037), and Port Clinton (pop.: 7,202) are the largest population
centers in the area and all contribute waste to the surface waters.

                                     Sandusky River

     The Sandusky River drains an area of 397,000 hectares (980,000 acres).   The
area is located in north central Ohio.  The Sandusky River has a mean annual dis-
charge of 8.6 m^/s (304 cfs).  Major tributaries to the Sandusy River are Tymochtee
Creek and Honey Creek.  The area is generally very flat and poorly drained.   An
extensive network of surface ditches and underdrains exists in the area.  Approximately
80 percent of the area is used in agriculture, about 10 percent urbanized, and about
5 percent forested.  The bedrock is principly composed of shale, dolomite and some sand-
stone.  The overlying material consists of silt and clay in the northern portion and
glacial till in the south.  The Sandusky River tends to be high in dissolved solids
which leach from the caleureous bedrock.  The cities of Tiffin (pop.: 21,596),
Freement (pop.: 18,490), and Bucyrus (pop.: 13,111) are the major population and
industrial centers in the Basin.

                                    Huron-Vermilion Complex

     The Huron-Vermilion Complex compasses and area of 267,000 hectares (661,000
acres) in north central Ohio.  The major rivers in the complex and their mean annual
discharges are the Huron River, 8.2 m3/s (290 cfs), and the Vermilion River 6.6 m^'s
(233 cfs).  A number of other small streams also drain this complex.  This area had a ro]
ing topography with relatively few wetlands. Approximately 80 to 90 percent of this
area is devoted to agriculture, about 5 percent urbanized, and about 5 percent
forested.  Bedrock is composed predominantly of sandstone and shale.  Overlying
material consists of glacial till with silt and clay near the shore.  Some sand,
gravel, and stone are extracted from the area.  Large population centers, such
as Sandusky (pop.: 32,674), Norwalk (pop.: 13,386), and Bellevue (pop.: 8,604)
utilize the Huron River for wastewater assimilation.  The Vermilion River receives
much less human pressure since its drainage area is relatively sparsely populated,
the largest city being New London (pop.: 2,336).

                                Black-Rocky Complex

     The Black-Rocky Complex encompasses an area of 230,000 hectares (568,000
acres).  This area is located in north central Ohio.  The major tributaries and
their mean annual discharges are the Black River 8.8 m^'s (311 cfs) and the Rocky
River 7.3 m^/s (258 cfs).  A number of other small streams drain the remaining
portions of this area.  The topography is rolling with relatively few wetlands.
Approximately 40 percent of the area is devoted to agriculture, about 15 percent
urbanized, and 15 percent forested.  The bedrock is composed predominantly of
shale near the lake shore and sandstone throughout the remaining area.  The
bedrock is covered mostly by a silt and clay mixture near the shoreline and
glacial till throughout the remaining portions.  The economy is heavily based
on manufacturing with some agriculture and mineral extraction.  Industrial waste,
treated municipal waste, and combined sewer overflows heavily influence water
quality, throughout the area.  The cities of Lorain (pop.: 78,185), and
Elyria  (pop.: 53,427) are the largest population centers on the Black River.
The city of Medina (pop.: 10,913) and part of Cleveland (pop.: 750,903)
utilize the Ricky River for wastewater assimilation.

     The Cuyahoga River drains an area of 234,000 hectares (578,000 acres) in
northeastern Ohio.  The Cuyahoga River has a mean annual discharge of 21.6 m^/s
(763 cfs).  The topography varies from rolling to steep hills with relatively few
wetlands.  Approximately 40 percent of the area is devoted to agriculture, 20
percent forested, and 20 percent urbanized.  The bedrock is composed predominantly
of shale near the shoreline and sandstone throughout the rest of the area.  The
overlying material is composed of silt and clay near the shore with an area of sand and
gravel in the southern portion, and glacial till throughout the remaining regions
The economy is based mainly on manufacturing.  Large amounts of municipal and
industrial wastewater enter the surface waters from metropolitan Cleveland (pop.:
750,903) and Akron (pop.: 275,425), as well as the cities of Cuyahoga Falls
(pop.: 49,678), and Kent (pop.: 28,103).  Steel and chemical industries are
prevelent along the Cuyahoga River.

with relatively few wetlands.  Approximately 40 percent of the area is agriculturalized,
about 25 percent forested, and about 20 percent urbanized.  The bedrock in the northern
portion of the area is predominantly composed of shale and to a lesser extent, sand-
stone.  The overlying material consists of mostly silt and clay near the shore .with
glacial till throughout the rest of the region.  The economy is based upon manufacturing
with some agriculture and mineral extraction.  The area is subject to heavy human
pressure from the cities of East Cleveland (pop.: 39,600), Willoughby (pop.: 18,634),
Chagrin Falls (pop.: 4,848) and portions of Cleveland (pop.: 750,903).  Sheet
erosion also causes a serious water quality problem.

                                   Grand River
     The Grand River drains an area of 212,000 hectares (525,000 acres)  in  north-
eastern Ohio.  The Grand River has a mean annual discharge of 18.7  m^'s  (660 cfs).
The major tributary to the Grand River is Mill Creek.   The topography of the area
is rolling with relatively few wetlands.   Approximately 40 percent  of the area is
agriculturalized, about 30 percent is forested, and about 20 percent  is  urbanized.
Bedrock is composed mostly of shale with some sandstone in the southern  portion.
The bedrock is covered by silt and clay near the shore and glacial  till  over the  rest
of the area.  The economy is based heavily on manufacturing.  The city of
Painesville  (pop.: 16,536) discharges a heavy industrial and minicipal wastewater
load to the Grand River.

                                 Ashtabula-Conneaut  Complex
     The Ashtabula-Conneaut Complex encompasses an area of 90,000 hectares (220,000
acres).   Fifty-four percent of the area is located in northeastern Ohio with the
remaining A6 percent in bordering Pennsylvania.  The major tributaries in the area
and their mean annual discharges are  the Ashtabula River A.I m^'s (1A5 cfs) and
the Conneaut Creek 7.2 m^/s (25A cfs).  The topography varies from flat to rolling
vith few wetlands.  The Ashtabula basin is characterized by high runoff.
Approximately 30 percent of the area is forested, about AO percent is devoted to
agriculture, and about 15 percent urbanized.  The bedrock is composed mostly of dolomite.
The bedrock is covered by a combination of silt and clay near the shore areas, and glacial
till throughout the remaining area.  The economy is based heavily upon manufacturing.
The lower reaches of the Ashtabula River are affected by municipal and industrial
wastewater discharges from the city of Ashtabula (pop.: 2A.313).  The Ashtabula
has a relatively small drainage basin and a relatively low flow, resulting in a low
dillution potential.  During periods of low natural flow, efflent from the
Ashtabula industrial complex dominates the rivers discharge.

     The Erie-Chautauqua Complex covers 169,000 hectares (418,000 acres).   Fifty-three
percent of the area is located in northern Pennsylvania, with the remaining 47
percent in New York.  There are a number of small streams draining the area but no
major rivers.  The area has a rolling relief with relatively few wetlands.
Approximately 45 percent of the complex is forested, about 35 percent is agriculturalizec
and about 10 percent is urbanized.  The bedrock is composed mostly of shale.
Overlying material consists of glacial till with some areas of silt and clay.   The
economy is based heavily upon manufacturing.  Despite the small size of the
tributaries in this area, they contribute a significant amount of wastewater to
Lake Erie.  The cities of Erie, Pennsylvania (pop.: 129,231), Fredonia, New York
(pop.: 10,326), and Dunkirk, New York (pop.: 16,855), are the major population
centers in this area.

     The Cattaraugus Creek drains an area of 144,000 hectares (355,000 acres) in the
southwest portion of New York.  Cattaraugus Creek has a mean annual discharge of
20.2 m  s (713 cfs).  The topography of the area is quite hilly with relatively few
wetlands.  Approximately 50 percent of the area is forested, about 35 percent if
devoted to agriculture, and about 10 percent is urbanized.  Bedrock consists mostly of
shale.  The overlying material is predominantly silt and clay near the shore,
glacial till in the more southern portions, and sand and gravel in the east.  The only
important wastewater point sources are discharged near the village of Gowanda
(pop.: 3,110), and the village of Arcade (pop.: 3,048).  Along with the city of
Springville (pop.: 4,350), these villages are the most highly populated zones within
this area.

Hydrologic Area 4.4.3
Tonawanda Complex
The Tonawanda Complex covers 371,000 hectares (917,000 acres) in the western
region of New York State. The major tributaries and their mean annual discharges are
Eighteen Mile Creek (ungaged), the Buffalo River 11.6 m-*'s (408 cfs), and Tonawanda
Creek 7.5 m^/s (265 cfs). Major tributaries to the Buffalo River are the Cazenovia
Creek and the Buffalo Creek. The topography of the area is rolling with relatively
few wetlands. Approximately 30 percent of the area is forested, about 30 percent is
devoted to agriculture, and roughly 20 percent is urbanized, including the
metropolitan Buffalo area. The bedrock is composed mostly of shale. The overlying
material consists principly of glacial till in the eastern portions and silt and
clay in the west. The economy is based almost entirely upon manufacturing. Eighteen
Mile Creek receives wastewater discharges from the Hamburg (pop.: 10,215) area. The
Buffalo River is subject to heavy industrial and municipal wastewater loadings from
the cities of Buffalo (pop.: 462,768), Lockport (pop.: 25,399), Depew (pop.: 22,158), an<
Lancaster (pop.: 13,365). Tonawanda Creek receives industrial and municipal wastewater
streams from the cities of North Tonawanda (pop.: 36,012) and Tonawanda (pop.: 21,898).

                                Niagara-Orleans Complex
     The Niagara-Orleans Complex covers 269,000 hectares (664,000 acres)  in north-
western New York.  Major tributaries drainaing this area are Johnson Creek and
Oak Orchard Creek, both of which are ungauged.  Many additional small streams drain
the remaining portions of this area.  The New York State barge canal also flows
through this complex.  The topography is relatively flat.  Approximately  50 percent
of this area is used for agricultural purposes, about 35 percent is forested,  and
roughly 10 percent urbanized.  The bedrock is composed mostly of shale and
dolomite.  The overlying material is mainly a mixture of silt and clay with some
glacial till.  The economy is based heavily upon manufacturing, with some
agriculture.  The cities of Medena  (pop.: 6,415), Albion (pop.: 5,112), Brock-
port  (pop.: 7,878), Niagara Falls (pop.: 85,615), and Rochester (only a portion
of the city falls in the watershed  pop.: 296,233) exert the greatest human
pressure on the area.  The cities of Niagara Falls and Rochester are heavily
industrialized and utilize the surface waters for large amounts of waste
assimilation.                       Station Key

                             Genesee River Complex
     The Genesee River drains an area of 642,000 hectares (1,586,000 acres).
Ninety-six percent of the area is located in western New York with the remaining
four percent in Pennsylvania.  The Genesee River has a mean annual discharge
of 76.8 m3/s (2,712 cfs).  Major tributaries to the Genesee River are the
Canaseraga Creek, the Otatka Creek, the Black Creek, and the Honeoye Creek.
A barge canal crosses the Genesee River south of Rochester.  Guard Locks, located
on either side of the river crossing, permit regulation of canal water diverted
from Lake Erie.  The River has a low slope and many meanders in the lower reaches
which results in generally sluggish flow and estuarine effects during low
flow conditions.  The southern region is characterized by steep rugged terrain,
changing to a gently rolling look in the north.  There are few wetlands.
Approximately 30 to 40 percent of the area is forested, roughly 50 percent is
devoted to agriculture, and about 10 percent is urbanized.  Bedrock is composed
mostly of dolomite and shale.  The overlying material is mostly glacial till
with some silt and clay.  Severe soil erosion occurs in the upper reaches of
the watershed.  The economy is based upon manufacturing and agriculture in the
northern areas with agriculture and forestry being the dominate influence in
the south.  Approximately four municipalities and three industries induce the
greatest pressure upon the river.  Discharge from the barge canal also seriously
degrades water quality in the river.  The city of Rochester (pop.: 296,233) at
the mouth of the Genesee River is the most highly industrialized region within
this hydrologic area.

are a number of smaller streams that drain the remainder of the complex.
The area has a rolling topography with relatively few wetlands.  Approximately
45 percent of the complex is forested, another 45 percent approximately is agricul-
turized and about 5 percent is urbanized.  The bedrock is composed pre-
dominately of dolomite.  The overlying material is largely silt and clay.
The cities of Sterling (pop.: 2,589) and Sodus (pop.: 1,813) are the largest
population centers in the area.

                               Oswego River


     The Oswego River drains an area of 1,316,000 hectares (3,252,000 acres) in
north ,central New York.  The Oswego River has a mean annual discharge of
183 m /s (6,462 cfs).  This area drains the bulk of New York's Finger Lakes
Region.   A significant feature of this complex is the New York State Barge
Canal which completely transects this complex in an east-west direction.  The
topography varies from rolling in the northern portions to mountainous in the
south.   There are some wetlands in the eastern region of this area.
Approximately 30 percent of the area is forested, about 40 percent is
agriculturized, about 5 percent is urbanized, and nearly 5 percent of the complex's
area is covered by lakes.  The large number of lakes has a modifying effect on
runoff.   The bedrock is composed largely of dolomite in the northern sections and
sahle in the south.  The cover material is composed mostly of glacial till with
some areas of sand and gravel.  The economy is based heavily upon manufacturing
with some agriculture and mineral extraction (limestone and dolomite, salt,
clay, and sahle).  The Oswego River receives heavy organic loadings from three
municipalities and six major industries scattered throughout the area.  Additional
treated wastewater loads are introduced by the New York State Barge Canal, and
over 60 industries scattered throughout the metropolitan Syracuse area.  The
cities of Syracuse (pop.: 197,208), Oswego (pop.: 23,844), Auburn (pop.: 34,599),
Ithaca (pop.: 26,226), and Fulton  (pop.: 23,844)., are the most populated and
industrilized centers in this area.

     The Salmon Complex encompasses an area of 273,000 hectares (674,000 acres) in
north central New York on the eastern shore of Lake Onatrio.  The major.,tributaries
in the area are Sandy Creek, which has a mean annual discharge of 6.9m /s (244
cfs), the Salmon River (ungaged), and the Little Salmon River (ungaged).  Many
additional small streams drain portions of this area.  The topography varies from
rolling to flat.  Wetlands are significant.  Approximately 50 percent of the
area is forested, about 40 percent is agriculturized, and roughly 5 percent is
urbanized.  Bedrock is composed mostly of shale.  The overlying material consists
of silt and clay near the lake shore and glacial till throughout the remaining
area.  The major population center in the area is the city of Pulaski
(pop.: 2,480).  There are no important wastewater discharges in the area.

                                   Black River
     The Black River drains an area of 521,000 hectares (1,289,000 acres) in
northcentral New York.  The Black River has a mean annual discharge of 110.0 m /s
(3,884 cfs).  Major tributaries to the Black River are the Moose River, the Beaver
River, and the Deer River.  The Black River and its tributaries have many natural
falls, which are used extensively for power generation.  The topography varies
from rolling near the lake shore to mountainous in the eastern states.  Annual
runoff in the Basin is high.  Some of the 30 hydroelectric developments in the
Basin cause alteration in the flow of the river system.  Approximately 60 to 70
percent of the area is forested, 20 to 30 percent is agriculturized, and about
5 percent is urbanized.  The bedrock consists predominately of igneous and meta-
morphic rock, although significant shale is found in the western portions.  The
overlying material predominantly consists of a silt and clay mixture near the lake
shore areas and glacial till throughout the remainder of the region.  Numerous
paper and pulp mills use the Black River for waste assimilation.  The cities of
Watertown (pop.: 30,787), and Carthage (pop.: 3,889) are the most populated and
industrialized centers within the area.

                                 Perch Complex
     The Perch Complex covers 126,000 hectares (311,000 acres) in north-central
New York.  The major tributaries draining this area are the Perch River, Chaumout
River, and Chippawa Creek, all of which are ungauged.  The area is generally flat
with few wetlands.  Approximately 60% of the land is forested, 40% is devoted to
agriculture,  with only a small fraction of the area urbanized.  The sandstone and
carbonate bedrock is overlain with silts and clays of a former lake bed.  The local
economy is based largely on agriculture, forestry, and food-processing activities.
Wastewater is discharged by several dairy plants, paper mills and small munici-
palities.  The largest population centers in this sparsely populated area are the
villages of Clayton (Pop: 1,970) and Dexter (Pop: 1,061).

                               Oswegatchie River
     The Oswegatchie River drains 430,000 hectares (1,063,000 acres) in north-
central New York.  The mean annual discharge into the St. Lawrence River is
81.4 m /s (2874 cfs).  Major tributaries to the Oswegatchie are the Indian River
and the West Branch.  Many natural lakes exist in the headwaters area and the river
itself has been extensively dammed for hydroelectric generation.  The topography
varies from flat and rolling near the mouth to mountainous in the upper reaches.
Runoff is high but streamflow is greatly regulated by the many impoundments along
the river.  Roughly 80% of the area is forested, 15% is agriculturized, and 5% is
in urban uses.  Bedrock consists of igneous and metamorphic rocks in the upper
mountainous reaches with carbonates and sandstones underlying the area near the
mouth.  Surface deposits in the lower reaches are mostly silt and clay lake bed
sediments, while the upper drainage area is mainly exposed bedrock with some
glacial till.  The local economy is based on forestry, dairying and mining (iron,
talc, zinc, and silver).  Paper mills and dairy plants contribute significantly
to tributary wastewater loads.  The major population centers, Ogdensburg
(Pop.: 14,554) and Gouverneur (Pop.: 4,574) also contribute wastewater from muni-
cipal and industrial sources.

                         Grass-Raquette-St. Regis Complex


          The Grass-Raquette-St. Regis complex covers an area of 823,000 hectares
(2,033,600 acres) in northcentral New York.  The major tributaries and their mean
annual discharges are the Grass River (32.6 m /s, 1150 cfs), the Raquette River
(61.7 m /s, 2180 cfs) and the St. Regis River (39.4 m /s, 1391 cfs).  The flow
of the Grass River is increased by diversion of a part of the St. Lawrence via
the Massena Power Canal at Massena.  Major tributaries to the Grass River are
Harrison Creek and the Little River; to the Raquette are the Bog River and Jordan
River; and to the St. Regis are the Deer River and the East and West Branches of
the St. Regis.  All three major rivers have their headwaters in the mountainous
Adirondack region and flow northerly onto the flat to rolling plain along the
St. Lawrence River.  There are many natural lakes and man made impoundments in
the upper reaches; the Raquette River is especially heavily utilized for hydro-
electric generation.  Many wetlands are present in the mountainous areas.  Approxi-
mately 75% of the region is forested, 20% is devoted to agriculture and 5% is in
urban usage.  Bedrock is composed for the largest part of crystalline rocks with
a smaller area along the St. Lawrence River underlain by sandstone and carbonates.
Surficial deposits consist of silt and clay in the lower reaches and areas of
both exposed bedrock and glacial outwash in the southern portion.  The economy
is based on mining, metals production, dairying, and forestry.  Aluminum production
utilizes much of the electric power generated within the region.  The Grass River
receives municipal effluent from Conton (Pop.: 6,398) and Massena (Pop.: 14,042)
and industrial wastes from aluminum plants, dairy processing plants, and ore re-
fineries.  The Raquette River is subject to industrial and municipal wastewater
loadings from the Potsdam (Pop.: 9,985), Norwood (Pop.: 2,098), and Tupper Lake
(Pop.: 4,854) areas.  The St. Regis River receives only small amounts of municipal
effluent but receives significant discharges from paper mills and food processing
plants.

     The Rifle-Au Gres Complex encompasses an area of 287,000 hectares  (709,000
acres).  This complex is located in the northeastern portion of Michigan's Lower
Peninsula.  The important rivers in the area and their mean annual discharges are
the Au Gres (2.8 m-*/s, 99 cfs), and the Rifle (8.7 m3/s, 307 cfs).  The Complex is
generally flat and wetlands are relatively common.  Approximately 70 to 80 percent
of the area is forested (including portions of the Huron National Forest), about
15 percent devoted to agriculture, and only a few percent is urbanized.   The bed-
rock is composed mostly of limestone.  The bedrock is covered by  silt and clay
along the lakeshore and glacial till throughout the rest of the area.  Material
such as sand and gravel, oil, gypsum, limestone, and dolomite are extracted from
the area.  The cities of East Tawas (Pop.: 2,372) and Tawas (Pop.: 1,666) represent
the two largest urbanized areas in this complex.

     The Kawkawlin Complex encompasses an area of 100,000 hectares (248,000
acres) in the Saginaw Bay area of Michigan's Lower Peninsula.  Important rivers
in the area are the Kawkawlin River, which has a mean annual discharge of 1.6 m^/s
(57 cfs), and the Pine River (ungauged).  The area is generally flat with some
wetlands.  Only about 10 percent of the area is forested, roughly 50 percent is
devoted to agriculture, and about 15 percent urbanized.  The bedrock is composed
of sandstone.  Overlying material consists of silt and clay near the shoreline
and glacial till over the remaining area.  The economy is based on manufacturing
and agriculture with some oil extraction.  Generally the waters are not influenced
by human activities.  The cities of Pinconing (Pop.: 1,320) and Kawkawlin are the
only areas of industrial activity.

                                   Saginaw River
     The Saginaw River drains an area of 1,617,000 hectares (3,995,000 acres).
The area is located in the east central portion of Michigan's Lower Peninsula.
Generally only maximum flows are measured at the river mouth of the Saginaw
River.  Major tributaries to the Saginaw River are the Cass River, Flint River,
Shiawassee River, and the Tittabawassee River.  The topography is mostly flat,
with rolling hills in the west.  Approximately 25 percent of the area is forested,
about 60 percent is agriculturized, and about 10 percent is urbanized.  The bed-
rock is composed mostly of limestone.  The soil is generally composed of a silt
and clay combination with glacial till in some areas.  The economy is based
heavily on manufacturing with some agriculture and mining of natural resources
such as oil, sand and gravel, salt, peat, and clay.  The cities of Saginaw, Bay
City and Flint are all heavy industrial areas and subject the surface waters  to
heavy wastewater loadings.  A large number of municipalities and industries use
the surface waters of ths Saginaw River and its tributaries for waste assimilation.
The cities of Flint (Pop.: 193,317), Saginaw  (Pop.: 91,849), Bay City (Pop.:
49,449), Midland (Pop.: 35,176), Mount Pleasant (Pop.: 20,504), and Owosso
(Pop.: 17,179) are the most highly developed urban centers in this area.

                               Hydrologic Area 3.2.3
                                   Thumb Complex
     The Thumb Complex encompasses an area of 367,000 hectares  (907,000 acres).
The area is located in the east central portion of Michigan's Lower Peninsula.
Important tributaries from the area and their mean annual discharges are the
Pigeon River (0.9 m3/s; 32 cfs), the Willow River (1.3 m3/s; 46 cfs), the
Pinnebog River (ungauged), and the Sebewaing River (ungauged).  The area is flat
with many additional small streams draining into Lake Huron.  The area is also
characterized by many man-made drains crossing over the countryside.  Less than
20 percent of the area is forested, about 60 percent is agriculturalized, and 5
percent is urbanized.  Bedrock is composed of sandstone.  Overlying material
contains glacial till as well as a silt and clay mixture.  The economy is based
mainly upon agriculture, although there is some manufacturing.  At least 5
municipalities and one industry discharge significant amounts of wastewater to
the surface waters of the area.  The cities of Bad Axe  (Pop.: 2,999), and Pigeon
(Pop.: 1,174) are the most highly developed centers in this sparsely populated
area.  Large portions of this complex are extensively drained by tile systems.
