RESEARCH REPORTING SERIES
Research reports of the Office of Research and Development, U.S. Environmental
Protection Agency, have been grouped into nine series. These nine broad categories
were established to facilitate further development and application of environmental
technology. Elimination of traditional grouping was consciously planned to foster
technology transfer and a maximum interface in related fields. The nine series are:
1. Environmental Health Effects Research
2. Environmental Protection Technology
3. Ecological Research
4. Environmental Monitoring
5. Socioeconomic Environmental Studies
6. Scientific and Technical Assessment Reports (STAR)
7. Interagency Energy-Environment Research and Development
8. "Special" Reports
9. Miscellaneous Reports
This report has been assigned to the ENVIRONMENTAL MONITORING series.This series
describes research conducted to develop new or improved methods and instrumentation
for the identification and quantification of environmental pollutants at the lowest
conceivably significant concentrations. It also includes studies to determine the ambient
concentrations of pollutants in the environment and/or the variance of pollutants as a
function of time or meteorological factors.

FOREWORD
Protection of the environment requires effective regulatory actions
based on sound technical and scientific information. This information must
include the quantitative description and linking of pollutant sources,
transport mechanisms, interactions, and resulting effects on man and his
envirorment. Because of the complexities involved, assessment of exposure to
specific pollutants in the environment requires a total systems approach that
transcends the media of air, water, and land. The Environmental Monitoring
Systems Laboratory--Las Vegas contributes to the formation and enhancement of
a sound integrated monitoring data base through multidiscipl inary multimedia
programs designed to:
t develop and optimize systems and strategies for moni-
toring pollutants and their impact on the environment
demonstrate new monitoring systems and technologies
by applying them to fulfill special monitoring needs
of the Agency's operating programs.
This report presents water quality data for the Atchafalaya Basin in terms
of geographical areas, seasonal patterns, and relationship of water quality to
flooding patterns. These data can be utilized to formulate plans to minimize
the environmental impact of proposed hydrological modifications. This report
was written for use by Federal, State, and local governmental agencies
concerned with water quality analysis, monitoring and/or regulation. Private
industry and individuals similarly involved with the Atchafalaya Basin will
find the document useful. For further information contact the Water and Land
Quality Branch, Monitoring Operations Division.

SUMMARY
The Atchafalaya Basin in south-central Louisiana is a large alluvial basin
whose wetlands are of national significance. The Basin extends inland from
the Gulf of Mexico for a distance of 125 miles (200 km) to the confluence of
Red River and distributary flows from the Mississippi River. To meet the need
for flood control, the U.S. Army Corps of Engineers is considering
hydrological modifications for the Basin. The Basin's present hydrological
cycle and complex water circulation patterns support one of the world's most
highly natural productive areas.
In response to a request by the Governor of Louisiana and a joint U.S.
Congressional resolution, the U.S. Environmental Protection Agency (EPA), U.S.
Army Corps of Engineers (USCE), and U.S. Department of the Interior (USDI),
are conducting a water and land quality study in the Atchafalaya River Basin.
The study's objectives are to assess the potential impact of proposed
hydrological modifications and to develop alternative land and water
management plans to accommodate flood flows and maintain an acceptable level
of environmental quality for the Atchafalaya Basin.
Objectives of the EPA in the Atchafalaya Basin include: 1) land use
requirements to control agriculturally related nonpoint sources of pollution
(Federal Water Pollution Control Act Amendment (FWPCAA), 1972, Sec. 208);
2) the 1983 goal of water quality, which provides for the protection and
propagation of fish, shellfish, and wildlife and provides for recreation in
and on the water, and the restoration and maintenance of the chemical,
physical, and biological integrity of the nation's water (FWPCAA, 1972, Sec.
101); 3) avoidance of degradation of waters that in their existing condition
could be used for sport fishing where such degradation would reduce their
value for that use; 4) reduction of the adverse impact of spoil disposal on
fishery, wildlife, or recreational areas (FWPCAA, 1972, Sec. 404); 5) moni-
toring of the discharge of dredged material in wetlands; 6) the avoidance of
long- and short-term adverse impacts associated with destruction and
modification of wetlands (Exec. Order 11990); 8) the avoidance of direct or
indirect support of new construction in wetlands (Exec. Order 11990); 9) the
avoidance, to the extent possible, of long- and short-term adverse impacts
associated with the occupancy and modification of flood plains (Exec. Order
11988); 10) the avoidance of direct or indirect support of flood plain
development whenever there is a practicable alternative (Exec. Order 11988);
and 11) the avoidance of discharged material that would have an unacceptable
adverse effect on municipal water supplies, shellfish beds, and fishery,
wildlife or recreational areas (FWPCAA, Section 404, C).

One of the major hydrological features of the Atchafalaya Basin is a
system of levees and floodways designed to confine and pass a "project flood"
through the Mississippi River Basin of 3,000,000 cubic feet per second (84,960
cubic meters per second). It is planned that 50 percent of the "project
flood" would be diverted through the Atchafalaya Basin, making it a vital and
necessary component of flood control works preventing natural disaster in
lower Louisiana. Because of the system of levees, the Basin can be divided
into two major areas, i.e., (1) the area totally encompassed by a system of
levees, and (2) the area outside the levee system.
The upper part of the Basin is largely used for agriculture. The middle
portion of the Basin within the levee system is known as the Atchafalaya Basin
Floodway. It is a semi-wilderness area dominated by swamps and lakes and
subject to frequent and prolonged natural overbank flooding. Emphasis was
given to examining the water quality of this portion of the Basin as it is
most subject to man-made hydrological modifications and is extremely
productive of aquatic life. The middle portion of the Basin outside of the
levee system has been isolated from historical influence of the Atchafalaya
River by the levees and water level patterns are now determined exclusively by
local runoff. Considerable agriculture exists in this area. The lower
Basin's environment is one of fresh and brackish water marshes and bays where
the development of the Atchafalaya River Delta is the most important process
affecting environmental quality.
Water and biological samples were collected from 148 stations in the
Atchafalaya Basin during the period 1974 to 1977. Waters in the Atchafalaya
Basin are extremely rich in nutrients as compared to Louisiana lakes and
eastern and southeastern lakes. However, autotrophic production in the
Atchafalaya Basin is much lower than the other lakes. Much of the lower
productivity can be attributed to light limitation due to mineral-induced
turbidity. Areas both within and outside the levee system are extremely rich
in phosphorus and nitrogen. However, the areas outside the levee system which
do not experience overbank flooding support higher standing crops of
phytoplankton and have higher dissolved oxygen concentrations than areas which
experience overbank flooding.
Significant amounts of suspended material settle out of the water as it
passes through the Atchafalaya Basin Floodway. Excessive deposition of
suspended material in the Basin is environmentally detrimental and is reducing
its flood-carrying capacity. The amount of suspended material passing a given
point is highly correlated with the total volume of water passing that point
and the deposition rates of suspended materials is a function of the amount of
material in suspension, other factors being equal. Western portions of the
Atchafalaya Basin Floodway receive three times the amount of water per unit
area as compared to the eastern segment of the Floodway. Only minor
differences in environmental parameters exist between the two segments. To
help alleviate the problem of sedimentation in the western segment, it is
recommended that flows per unit area be reduced to approximate those in the
eastern segment of the Floodway, as long as the extent, duration, and depth of
natural flooding is not greatly reduced.

-------
Dissolved oxygen concentrations are one of the most important gauges of
the Basin's water quality and its ability to support a well-balanced aquatic
fauna. Depressions of dissolved oxygen levels in the Atchafalaya Basin
Floodway adversely impact resident populations of aquatic life. Two separate
phenomena create most of the conditions under which reduced dissolved oxygen
levels exist: (1) rapid decomposition of newly inundated forest litter and
herbaceous vegetation during periods of flooding and draining of backwater
areas; and (2) increased biological activity associated with warm summer
temperatures in combination with receding water levels. It is extremely
important to maintain proper water circulation patterns in the overflow areas
of the Atchafalaya Basin Floodway during high water periods to prevent large
areas from having extreme DO depressions which adversely impact resident
populations of aquatic life.
The key to the high productivity of the Atchafalaya Basin Floodway is the
short, efficient, bacteria-detritus food chain. Organic matter processed
through bacterial metabolism represents the foundation of the system.
Nitrogen and phosphorus levels are sufficient for bacterial metabolism of
organic matter, regardless of geographical area, season, or water level.
Prolonged overbank flooding, with the inundation of additional land areas
containing herbaceous material and forest litter, renews the carbon resources
needed to drive the bacteria-detritus system. To maintain the highly
efficient bacteria-detritus food chain, the extent, duration and depth of
natural flooding must be maintained to the greatest degree possible.
As a participant in the planning process for the development of a multiuse
management plan for the Atchafalaya Basin, the EPA is using the results of
this study to make recommendations, enforceable through its responsibilities,
to ensure that Federal environmental requirements and objectives are
sufficiently considered in the selection of a final plan for management of the
critical wetland area of the Atchafalaya Basin.

INTRODUCTION
The Atchafalaya Basin is a large shallow depression located in the deltaic
plain of the Mississippi River in southern Louisiana. The Basin is an area of
national importance which provides extensive natural resources as well as
habitat for rare and endangered species. However, the Basin must also serve
as a floodway to pass a "project flood" through the Mississippi River Basin of
3,000,000 cubic feet per second (cfs) (84,960 cubic meters per second (cms).
It is planned that 50 percent of the "project flood" would be diverted through
the Atchafalaya Basin, making it a vital and necessary component of flood
control works preventing natural disasters in lower Louisiana.
In response to a request by the Governor of Louisiana and a joint U.S.
Congressional resolution, the U.S. Environmental Protection Agency (EPA), U.S.
Army Corps of Engineers (USCE), and U.S. Department of the Interior (USDI) are
conducting a water and land quality study in the Atchafalaya Basin. The
study's objectives are to assess the potential impact of proposed hydrological
modifications and to develop alternative land and water management plans to
accommodate flood flows and maintain an acceptable level of environmental
quality for the Atchafalaya Basin.
As part of the Atchafalaya Basin Water and Land Quality Study, we analyzed
water and biological samples collected from 148 stations during the period
1974 to 1977. The purpose of this report is to: 1) describe water quality in
the Atchafalaya Basin in terms of geographical areas, seasonal patterns, and
its relationship to water regimes; and 2) compare water quality in the Basin
to water quality in other Louisiana lakes, and eastern and southeastern lakes
as determined by the EPA's National Eutrophication Survey (NES). Emphasis in
this report is given to water quality in the Atchafalaya Basin Floodway, i.e.,
that portion of the Atchafalaya Basin subject to frequent and prolonged
natural overbank flooding and most subjected to hydrological modifications by
man.
-------
CONCLUSIONS
1) Because of a system of levees, the Atchafalaya Basin can be divided into
two major areas, i.e., the area totally encompassed by a system of levees
and the area outside the levee system. The middle portion of the Basin
within the levee system is known as the Atchafalaya Basin Floodway. It
is a semi-wilderness area dominated by swamp and lakes and subject to
frequent and prolonged natural overbank flooding. This area is extremely
productive of aquatic life and is most subject to man-made hydrological
modifications.
2) Waters in the Atchafalaya Basin are extremely rich in nutrients as
compared to Louisiana lakes and eastern and southeastern lakes. However,
autotrophic production in the Atchafalaya Basin is much lower. Most of
this lower productivity can be attributed to light limitation due to
mineral-induced turbidity.
3) Areas both within and outside the levee system are extremely rich in
phosphorus and nitrogen. However, the areas outside the levee system
which do not experience overbank flooding support higher standing crops
of phytoplankton and have higher dissolved oxygen concentrations than
areas which experience overbank flooding.
4) Significant amounts of suspended material settle out of the water as it
passes through the Atchafalaya Basin Floodway. Excessive deposition of
suspended material in the Basin is environmentally detrimental and is
reducing its flood carrying capacity.
5) The amount of suspended material passing a given point is highly
correlated with the total volume of water passing that point and the
deposition rate of suspended material is a function of the amount of
material in suspension, other factors being equal.
6) Even though the western segment of the Atchafalaya Basin Floodway
receives about three times the amount of water per unit area as the
eastern segment, there are only minor differences in environmental
parameters between the two areas.
7) In order to reduce the potential for sediment deposition, flows in the
western segment of the Atchafalaya Basin Floodway could be reduced to
approximate those in the eastern segment of the Atchafalaya Basin
Floodway, without adversely affecting environmental quality.
-------
8) Levels of chlorophyll jj increase considerably in the area within the
levee system during the warmer summer months. Also, during this period
there is a dramatic increase in ammonia-nitrogen values due to increased
bacterial action primarily associated with bottom sediments.
9) Total phosphorus, orthophosphorus, nitrite-nitrate-nitrogen, and light
penetration levels are lower during low-water conditions in the
Atchafalaya Basin Floodway than during high-water conditions while the
reverse is true for dissolved oxygen, temperature, ammonia-nitrogen and
Kjeldahi-nitrogen.
10) Dissolved oxygen concentrations are one of the most important gauges of
the Atchafalaya Basin's water quality and its ability to support a
well-balanced aquatic fauna. Depressions of dissolved oxygen levels in
the Atchafalaya Basin Floodway adversely impact resident populations of
aquatic life.
11) Two separate phenomena create most of the conditions under which reduced
oxygen levels exist within the Atchafalaya Basin Floodway: (a) rapid
decomposition of newly inundated forest litter and herbaceous vegetation
during periods of flooding and draining of backwater areas, and (b)
increased biological activity associated with warm summer temperatures in
combination with receding water levels.
12) Most of the extremely low dissolved oxygen concentrations during high-
water conditions in the Atchafalaya Basin Floodway occur in areas
shielded from extensive wind action or with little or no water
circulation due to man-made or natural obstructions.
13) Proper water circulation patterns must be provided for in the overflow
areas of the Atchafalaya Basin Floodway during high water periods in
order to prevent large areas from having extremely low dissolved oxygen
concentrations adversely impacting resident populations of aquatic life.
14) The key to the high productivity of the Atchafalaya Basin Floodway is the
short, efficient, bacteria-detritus food chain.
15) Prolonged overbank flooding in the Atchafalaya Basin Floodway, with the
inundation of additional land areas containing herbaceous materials and
forest litter, renews the carbon resources needed to drive the
bacteria-detritus system.
16) To maintain the highly efficient bacteria-detritus food chain in the
Atchafalaya Basin Floodway, the extent, duration, and depth of natural
flooding must be maintained to the greatest degree possible.
-------
RECOMMENDATIONS
1) In order to reduce the potential for sediment deposition, reduce flows per
unit of area in the western segment of the Atchafalaya Basin Floodway to
approximate those in the eastern segment of the Atchafalaya Basin
Floodway.
2) In order to prevent large areas of the Atchafalaya Basin Floodway from
having extremely low dissolved oxygen concentrations, provide proper water
circulation patterns in the overflow areas during high water periods.
3) In order to provide the short, efficient bacteria-detritus food chain,
upon which the high productivity of the Atchafalaya Basin Floodway is
dependent, maintain to the greatest degree possible the extent, duration,
and depth of natural flooding.
-------
DESCRIPTION OF BASIN
The Atchafalaya Basin comprises a 4,662-square kilometer (km2) lowland
area confined between natural levee ridges that delineate the present and
former courses of the Mississippi River (Figure 1). The overall dimensions of
the Basin are approximately 72 by 193 kilometers (km) with elevation ranging
from 15 meters (m) to sea level.
The natural boundaries of the Basin on the east are crests of the natural
levee ridges of the Mississippi River and the LaFourche Distributory, and on
the west the natural levee of the Teche Ridge. Its northern boundary is
delineated by the Red River and the Old River Outlet Channel which diverts
water from the Mississippi River. To the south the Basin opens into a
estuarine system. The upper portion of the Basin is largely used for
agriculture. Much of the middle portion of the Basin is a semi-wilderness
area dominated by swamps and lakes. The lower portion of the Basin, south of
the Teche Ridge is estuarine in character.
The Basin above Teche Ridge contains one of the largest remaining alluvial
hardwood swamps in the United States, containing more than 1,700 km2 of
hardwoods, nearly one-third of which are cypress-tupelo swamps, and 260 km2 of
permanent water bodies. Below the Teche Ridge the Basin's environment is one
of fresh and brackish water marshes and bays where the development of the
Atchafalaya River Delta is the most important process affecting environmental
quality.
The developing Atchafalya River Delta, below the Teche Ridge, offers the
potential development of 777 km2 of new wetlands, in a state where loss of
wetlands amounts to a staggering 41 km2 per year. The importance of the
Atchafalaya River Delta development is readily realized when considering the
maintenance of Louisiana's coastal renewable resources rests solely on the
growth of new delta complexes to replace those being lost to subsidence and
erosion. The only major physical development that now counters the slow
disintegration of the entire Mississippi delta system is the growth of the
Atchafalaya Delta. The estuarine environment and the fresh and brackish water
marshes and bays being formed by this rare and active river delta will support
extensive productive wetlands, if allowed to develop naturally.
The Atchafalaya Basin north of the Teche Ridge can be broken into six
segments (Figure 2) which have integrity due to man-made levee systems. These
are: (1) Morganza Floodway, (2) West Atchafalaya Floodway, (3) Pointe Coupee
Sump Area, (4) Atchafalaya Basin Floodway--historically subject to frequent
and prolonged natural flooding, (5) leveed Atchafalaya River and other
segments located mainly between the upper Atchafalaya River Levees and Old
River, and

(6) East and West Basin areas isolated by levees. Also, south of the Teche
Ridge there are extensive coastal marshlands as well as vast areas of
estuarine and Gulf of Mexico water associated with and affected by water
quality in the Atchafalaya River (Figure 2).
One of the major hydrological features of the Basin is the system of
levees and floodways designed to confine and pass a "project flood" through
the Mississippi River Basin of 3,000,000 cfs (84,960 cms) at the latitude of
Old River (Figure 3). One-half of the "project flood" would be diverted
through the Atchafalaya Basin.
Water enters the Basin from two major sources. A portion of the
Mississippi River water flows through the Old River Control structures
(Figure 2) and eventually joins with the Red River to form the main stem of
the Atchafalaya River. The Atchafalaya River receives approximately 30
percent of the combined flows of the Mississippi and Red Rivers at the
latitude of the Old River Control structures. Atchafalaya River discharges
show both seasonal and annual variation. The average monthly discharge
hydrography for the Atchafalaya River at Simmesport for the period of
1963-1971 indicates the seasonality of flows (Figure 4). The flow generally
begins to increase in December or January and crests in the period between
April and early June. The flows normally drop off sharply to their seasonal
lows in late summer and early fall. The cyclic nature of flow also describes
the typical annual regime of overflow for the Atchafalaya Basin Floodway. The
other segments of the Basin are not subjected to the same type of prolonged
overbank flooding. However, the extensive swamps and freshwater-to-saline
marshes south of Morgan City are also greatly influenced by the cyclic
discharge of the Atchafalaya River, besides local runoff, and tidal
conditions.

MATERIALS AND METHODS
SAMPLING STATION SELECTION
Sampling stations were selected so as to define water quality,
productivity, and fixed energy and nutrient export. The 148 sampling stations
were:
1. geographically distributed throughout the Atchafalaya Basin,
2. located at the major inlet and outlets to the Atchafalaya Basin
Floodway, and
3. located at major water exchange points within the Atchafalaya Basin
Floodway.
SAMPLE COLLECTION AND ANALYSES
Helicopters were employed to collect water and biological samples on 14
separate occasions from 1974 to 1977 in which 80 to 130 stations were sampled
throughout the Basin in approximately 10 days. The use of helicopters allowed
for complete geographical coverage, including remote areas. The frequency of
sampling was approximately quarterly, but due to other priorities imposed upon
helicopter usage, schedules were not rigidly maintained. The sampling team
consisted of a limnologist, pilot, and sampling technician, operating from a
pontoon-equipped Bell UH-1H helicopter.
The helicopters were equipped with an electric winch and approximately 200
feet of hollow-core, multi-conductor cable attached to a submersible pump and
an Interocean systems sensor package capable of making in situ measurements of
conductivity, temperature, optical transmissivity, depth and pH. Rack-mounted
equipment located inside the helicopter provided analog recording capabilities
and a digital display of the sensor values. An echo sounder, Secchi disc,
sample containers, and related equipment items necessary for water sampling
were also carried in each helicopter.
After landing at the approximate sampling site, the helicoter was
water-taxied to the sampling site. When necessary, a small buoy was deployed
to serve as a reference to the pilot for maintaining the helicoter on station.
Secchi disc measurements were made and bucket-dipped surface water samples
were collected. In fast flowing waters the helicoter was allowed to drift and
only surface samples were collected. In a previous study, the U.S. Department
of Interior (1969) demonstrated that in fast flowing waters in the Atchafalaya
Basin physical factors and chemical constituents were uniformly mixed.

-------
After the sensor-pump package was immersed, sensor outputs were checked,
analog recorders were activated and the sensor package was lowered slowly
through the water column until it contacted bottom. It was then raised to a
point just off the bottom to avoid pump damage from bottom sediments entering
the intake. The digital readout of each sensor at that depth was recorded on
the field data sheet and the submersible pump was activated. Water samples
were collected after allowing sufficient time for the pump to completely purge
the hollow cable of water from the previous station. (Purge times were
routinely measured for the system). Sampling depths for the collection of
other water samples were chosen after inspection of the analog strip-chart
records to best represent the water column. Upon completion of sampling near
the bottom, the sensor was raised to the next level, the digital values were
recorded, the hose was purged, and the water samples were pumped. This
process was repeated at each depth selected for collection of water samples at
a given site. However, in extremely shallow water or in fast flowing water,
samples were collected only from the surface.
Integrated samples for chlorophyll a^ and carbon analysis were collected by
continuing to pump while raising or lowering the sensor package. Water
collection for chlorophyll _a analysis was timed to provide a uniform mixture
of water from the lower limit of the photic zone to the surface while water
for carbon analysis was integrated from the surface to the bottom.
At each sampling depth, water samples were collected for nutrient, carbon
analysis, alkalinity, pH, conductivity, and dissolved oxygen determinations.
For nutrient analysis, two 4-ounce sample bottles were filled and the samples
immediately preserved with 0.25 ml of mercuric chloride solution
(25 g HgCl2/l of water).
Samples for dissolved oxygen determinations were collected in 300-ml BOD
bottles, immediately fixed with Hach powder pillow reagents, and stored out of
direct sunlight. Samples for pH, conductivity, and chlorophyll a^ analysis
were collected in polyethylene bottles and refrigerated in the dark until
completion of the day's sampling operation.
Electrode detenninations for pH were made as soon as possible following
their delivery to the field laboratory at the end of the day's sampling.
Portable pH meters and combination electrodes were used to determine pH.
Dissolved oxygen samples were titrated with phenylarsine oxide in the field
laboratory within 16 hours after collection.
Chlorophyll a^ analyses were performed at the end of each day in the field
laboratory. One of each pair of nutrient samples was filtered through a type
HA 0.45-micron Millipore filter into a clean unused polyethylene bottle,
recapped, and along with its unfiltered counterpart, forwarded to
Environmental Monitoring Systems Laboratory, Las Vegas for analysis.
Upon receipt at the field laboratory in Baton Rouge, the pair of carbon
samples were preserved with phosphoric acid to a pH of below 2. One of the
pair was filtered through a type HA 0.45-micron Millipore filter into a clean
12
-------
unused polyethylene bottle and recapped. Both of these samples were then
refrigerated for subsequent analysis. Analyses were performed either within
30 days with a Dohrman-52 carbon analyzer (EPA, 1974) or after the samples
were sealed using an Oceanographic International ampule sealer, at a later
date using an Oceanographic International carbon analyzer (EPA, 1974). .
Intensive sampling of five areas (Fordouche, Buffalo Cove, Pat Bay, inlet
of the Basin Proper, Atchafalaya River main stem, and the outlets of the Basin
Proper-Wax Lake and Morgan City) was conducted using small boat crews on
approximately a monthly basis. Two 18-foot John boats equipped with
50-horsepower Mercury outboard motors were used. The boats were equipped with
an electric winch and 100 feet of hollow-core cable attached to a pump. The
cable was lowered to the bottom and then raised to a point just off the bottom
to avoid sediments entering the intake. Water samples were collected at
various depths by raising the cable and pumping water samples into the boat.
However, in extremely shallow or fast flowing water, only surface samples were
collected. The same type of physical, chemical and biological data and
samples were collected as previously described. After completion of a
sampling day, the small boat crew(s) would return to the most convenient
location, either the field laboratory or a laboratory houseboat. Analysis of
samples was then performed at either location as previously described.
The EPA's National Eutrophication Survey (NES) sampled 249 lakes in 13
eastern and southeastern states in 1973 while 17 Louisiana lakes were sampled
in 1974. Each lake was sampled during the spring, summer, and fall using the
same pontoon-equipped helicopters used in the Atchafalaya study. In fact, the
identical methods and equipment were used as described above for the NES study
except:
1. carbon samples were not collected, and,
2. depth-integrated samples for chlorophyll a^ were uniform mixtures
of water from the surface to a depth of 4.6 m (15 feet) or from the
surface to the lower limit of the photic zone, whichever was greater.
The analytical methods used to process the nutrient samples at the
Environmental Monitoring Systems LaboratoryLas Vegas are outlined in Table
1. All of the analyses were performed using adaptations of automated
procedures described in "Methods for Chemical Analysis of Water and Wastes"
(EPA, 1971). Details of adaptations are given in EPA (1974a, 1975).
The analytical methods used to process water samples at the Baton Rouge
field station are listed in Table 2. All of the analyses were performed in
accordance with the procedures described in "Methods for Chemical Analysis of
Water and Wastes" (EPA, 1974), except for chlorophyll e[ and water
transparency. Chlorophyll a^ analyses were performed according to the
fluorometric procedure described by Yentsch and Menzel (1963) while water
transparency was measured in the field by Secchi disc readings as described by
Welch (1948).

DATA MANAGEMENT
Data collected by the Atchafalaya Basin Water and Land Quality Study and
NES were stored in STORET and manipulated as prescribed by Bliss et al.
(1975).
Atchafalaya Data
Basic calculations for parameters measured by the Atchafalaya Basin Water
and Land Quality Study were performed in such a way to give equal weight to
each depth sampled at a station on a particular day, each day sampled at a
station during a time interval, and each station sampled in a given
geographical area during a time interval.
Mean parameter values for each day sampled at a station were calculated as
follows:
pan / D (1)
where parjk = mean value for a parameter at the jth sampling station on
the kth day,
par-j = value for the ith depth, and
D = the number of depths for which a parameter was sampled at the
jth sampling station on the kth day.
Mean parameter values for each sampling station during a time interval
were calculated as follows:
E
= £ parjk / E (2)
k=l
where parj = mean value for a parameter at the jth sampling station
during a time interval, and
E = the number of days the jth sampling station was sampled
during a time interval.
Mean parameter values for a geographical area during a time interval were
calculated as follows:
S
== _
par - E parj / S (3)
23
-------
where pfr = mean value for a parameter in a geographical area during a time
interval , and
S = the number of sampling stations in a geographical area sampled
during a time interval .
If a parameter was not sampled on at least three_different days during a
time interval, the station's mean parameter value (pan) was_npt used in
formula 3 in determining the mean value for the parameter (pa~r) in a
geographical area during a time interval.
Formulas 1, 2, and 3 were used to determine parameter values for total
phosphorus (TP), dissolved orthophosphorus (OP), ammonia-nitrogen (NHaN),
nitrite-nitrate-nitrogen (NQ^NOaN), Kjeldahl -nitrogen (TKJEL), total
alkalinity (TALK), Secchi disc transparency (SECCHI), dissolved oxygen (DO),
collected by the Atchafalaya Basin Water and Land Quality Study. Unlike the
above parameters where measurements were made at various depths, only one
chlorophyll ^ (CHLA), total organic carbon (TOC), and dissolved organic carbon
(DOC) measurement was made at any individual sampling station on a given day.
Therefore,
CfOjk = CHLA, (4)
TCCjk = TOC, and (5)
DOCjk = DOC, (6)
where CHLAjk, TOCjk, and DOCjk = the mean value for the parameter at
the jth sampling station on the
kth day, and
CHLA, TOC, and DOC = the parameter value for an integrated
sample taken at the jth sampling station
on the kth day.
Particulate organic carbon (POC) parameter values were derived by
subtracting DOC values from TOC values. Therefore,
(7)
where POTjk = the mean value for POC at the jth sampling station on the
kth day
However, if DUCj exceeded TO~Cj on the kth day because of analytical error,
the POTjk and TTJCjk were not used in determining the POCj.
The ratio of TP to inorganic nitrogen (NHaN = NOaNOaN) at a sampling
station on a given day was calculated as follows:
N02NOsNjk
(8)
24
-------
however, if at the formula 1 level TP, NHsN, or NC^NOaN was missing at the
ith depth, all three nutrient components were deleted in determining the
value.
Standard deviations for mean parameter values (paTj) at a sampling ,
station during a time interval were calculated from the mean parameter values
(pcTrj|<) for each day sampled at the station while standard deviations for
mean parameter values (par) in a geographical_area during a time interval were
calculated from the mean parameter values (paTj) for each sampling station
in the geographical area.
NES Data
Data calculations for parameters measured by NES were performed in such a
way as to give equal weight to each depth sampled at a station, each station
sampled in an individual lake during a sampling round, each sampling round on
an individual lake, and each lake in a geographical area.
Mean parameter values for each NES sampling station were calculated as
follows:
D
= £ pan / D (9)
1-1
where paTj = mean value for a parameter at the jth sampling station
during a sampling round,
par^ = value for the ith depth, and
D = the number of depths for which a parameter was measured at the
jth sampling station during a sampling round.
Mean parameter values for each sampling round were calculated as follows:
_ S
park = E parj / S (10)
where paT\ = mean value for the kth sampling round on a given lake, and
S = number of sampling stations.
Mean lake parameter values for a given sampling year were calculated as
follows:
pan = L park / 3 (11)
k=l
where pan = mean parameter value for the 1th lake.
25
-------
Mean parameter values for the lakes in a geographical area were calculated
as follows:
__ L _
par = £ pTf i / L (12)
1=1
where =par = mean value for a parameter in a geographical area, and
L = the number of lakes sampled in the geographical area.
Lake parameter values were calculated only when values were available for
the first, second, and third sampling rounds during a given sampling year from
a lake. Formulas 9, 10, 11, and 12 were used to determine parameter values
for TP, OP, NH3N, N02N03N, TKJEL, SECCHI, DO, TALK, and PH for NES data.
The ratio of TP to inorganic nitrogen (NH3N + N02N03N) at a sampling
station on a given day was calculated as follows:
however, if TP, NH3N, or N02N03N was missing at the ith depth, all three
nutrient components were deleted in determining the "FPP value.
Unlike the above parameters where measurements were made at various
depths, only one CHLA measurement was made at any individual sampling station
during a sampling round. Therefore,
CHTAj = CHLA (14)
where CHLAj = the mean CHLA concentration for the jth sampling station
during a sampling round, and
CHLA = the CHLA concentration from an integrated water sample.
Standard deviation for mean parameter values (l^ar) in a geographical area were
calculated from the mean parameter values (pa^|) for each lake in the
geographical area.

RESULTS AND DISCUSSION
STATION DATA
Appendix A summarizes the water quality data collected in the Atchafalaya
Basin Water and Land Quality Study. The appendix presents station means for
all variables, with the number of days sampled, standard deviations of means,
and minimum and maximum daily means.
COMPARISON OF BASIN TO OTHER AREAS
NES sampled 249 lakes located in 17 eastern and southeastern states
exclusive of Louisiana in 1973 (Table 3) while 17 Louisiana lakes outside of
the Atchafalaya Basin were sampled in 1974 by NES (Table 4). Data from these
lakes are compared to those from the Atchafalaya Basin (Table 5). NES data
collected from water bodies located within the Atchafalaya Basin were not
included with the NES data. The three sets of data are comparable as the same
analytical techniques were employed. However, temperature data are not
comparable as the NES lakes were sampled on only a seasonal basis (spring,
summer, and fall) while Atchafalaya Basin stations were sampled throughout the
year. In addition, carbon moieties (TOC, DOC, or POC) were not determined in
the NES studies.
Waters contained within the Atchafalaya Basin are rich in nutrients.
While TP values were extremely high for all three sets of data, the
Atchafalaya Basin had the highest mean concentration of TP (199 yg/1). By
comparison, various limnologists, e.g., Vollenweider (1975), Dillon (1975),
and Larsen and Mercier (1976) utilize a mean yearly value of 20 yg/1 or above
of ambient TP as being indicative of an eutrophic state. In direct
contradiction, Well annd Demas (1977) state that TP concentrations in the
Atchafalaya Basin are relatively low because values are generally less than
150 yg/1.
Inorganic nitrogen (NH3N + N02N03N), TKJEL, OP, DO, and pH means recorded
for the Basin are higher than in other Louisiana lakes but lower than other
eastern and southeastern lakes.
The mean inorganic nitrogen levels for the Atchafalaya Basin are
relatively high (462 yg/1) (149 yg/1 N02N03N + 313 yg/1 NH3) = 462 yg/1) when
compared to Louisiana lake means (180 yg/1). Sawyer (1947) suggested that in
lakes concentrations at spring overturn of 300 ug/1 or over of inorganic
nitrogen with sufficient phosphorus was the critical level of nitrogen for the
development of algal blooms. However, the Basin had a very low N-P ratio mean
(3:1).

The CHLA mean for the Atchafalaya Basin was approximately half (11.0 ug/1)
as high as the means for Louisiana lakes (19.3 yg/1) and the other NES lakes
(26.3 yg/1). Light penetration, as measured by SECCHI, was approximately
twice as high in Louisiana lakes (39 in) (99 cm) and three times as high in
other NES lakes (48 in) (122 cm), on an average, as that in the Atchafalaya
Basin (17 in) (43 cm).
The mean DO level for the Atchafalaya Basin was 6.3 mg/1 while the mean
percent of saturation was 67. However, DO levels and other parameter values
vary dependent upon geographical area, season, and water stages as will be
discussed in subsequent sections.
GEOGRAPHICAL DIFFERENCES
Parameter means for 20 geographical areas of the Atchafalaya Basin shown
in Figure 12 are presented in Appendix B. The stations which are contained
within each of the 20 geographical areas are presented in Table 6. The entire
Atchafalaya Basin was divided into two major categories, i.e., areas totally
encompassed by a system of levees referred to as the "leveed Atchafalaya
system" and the areas "outside the leveed system."

The leveed Atchafalaya system consists of the inlet to the system, the
West Atchafalaya Floodway north of U.S. 190, the Morganza Floodway north of
U.S. 190, the Atchafalaya Basin Floodway exclusive of the Fordouche area, the
Fordouche area, and the outlets of the system (Figure 12).
The combined flow of the Red River and water diverted from the Mississippi
River form the Atchafalaya River which enter the leveed Atchafalaya system at
Simmesport. The combined flow is confined by artificial levees for the first
84 km. Inlet stations are located in the fast, well-mixed waters between
Simmesport and Krotz Springs (Figures 6 and 7).
The upper leveed Atchafalaya system, north of U.S. Highway 190, is
composed of the West Atchafalaya Floodway and the Morganza Floodway. Internal
Atchafalaya River levees have eliminated prolonged overbank flooding, allowing
agricultural development within these areas with the concomitant requirement
for better drainage (Figure 5). These floodways are only used during major
floods along the Mississippi River.
Certain areas within the Atchafalaya Basin Floodway were also examined
i.e., Buffalo Cove, Upper Belle River and the Upper Flats (Figure 12). These
areas were selected to compare water quality in eastern and western swamps

because of the differences in the total amount of water they receive per unit
area. Diversion of water per unit of area for the western and eastern
floodway segments, respectively, are on the order of 250 cfs/mi2 (18.3
cms/knfc) and 75 cfs/mi2 (5.5 cms/km2) for an Atchafalaya River discharge of
425,000 cfs (12,036 cms) measured at Simmesport, Louisiana (van Beek et al.,
1978). These estimates are admittedly rough when applied to specific
geographical areas of the Atchafalaya Basin Floodway. However, they do
suggest that on a relative basis the western segments receive about three
times the amount of water per unit of area as the eastern segments.
The Buffalo Cove area is representative of the western segment while the
Upper Flats and the Upper Belle River areas would represent eastern segments
of the floodway. The Buffalo Cove area, comprising some 230 km2, is located
50 km south of the Fordouche area and is bounded by natural levees and
spoil-elevated natural levees. Sediments have largely filled in the northern
one-third of the swamps compared to the rest of the area which contains a few
permanent water bodies. The Grand Lake area of the Atchafalaya Basin Floodway
was examined because it represents an open water area where optimal aeration
from turbulance (wind, rain) is possible. The subareas of the Atchafalaya
Basin Floodway (Fordouche, Upper Flats, Upper Belle River, Buffalo Cove and
Grand Lake) are presented on Figure 12 with dashed lines. The Upper Belle
River, Grand Lake and the Upper Flats areas are not distinct geographical
areas defined by natural boundaries but rather areas where sample collections
were made.
The Fordouche area which is normally considered to be a part of the
Atchafalaya Basin Floodway was separated from the floodway in this report.
While both of these areas experience prolonged overbank flooding with seasonal
water-level patterns which mimic the Atchafalaya River, local runoff from
outside the leveed Atchafalaya system and Atchafalaya River water contribute
to the annual flooding of the Fordouche area while the rest of the Atchafalaya
Basin Floodway receives water mainly from the Atchafalaya River.
The Fordouche area covers approximately 220 km2 of the Basin. Ridged
boundaries delineate the area as a hydrological unit. East and west
boundaries are formed by continuous levees of the Atchafalaya River an the
external levee system. U.S. Highway 190 and railroad embankments form the
northern boundary, while a natural levee ridge bounds the area to the south.
The flooding of the area is a modified backwater flooding regime. Atchafalaya
River water, during high water months, enters across the southern boundary
through the West Atchafalaya Basin Protection levee barrow pit after diversion
from the river into Bayou Butte La Rose (Figure 8). The water then flows
north through Henderson Lake and northern swamps in accordance with the river
stage. Introduction of local runoff from outside the Fordouche area occurs
across the northern boundary and through the Bayou Courtableau structure
(Figure 7). Dewatering of the Fordouche area occurs by flow through the West
Atchafalaya Basin Protection levee barrow pit and is also dependent on river
stages.
35
-------
Dewatering of the entire Atchafalaya Basin occurs through two major
outlets. The water at either outlet is constricted as the river regains its
identity after flowing through numerous channels, swamps, bayous, and sloughs
until it exits the Atchafalaya Basin Floodway either at the Wax Lake outlet or
the Morgan City outlet. Approximately 30 percent of the flow leaves the
leveed Atchafalaya system at the Wax Lake outlet while 70 percent is
discharged through the Morgan City outlet. At either outlet the water is fast
and well-mixed.
The areas outside the leveed Atchafalaya system which were examined
include Courtableau, Fausse Point Basin exclusive of Bayou Teche, Bayou Teche,
Verret Basin and the area south of Morgan City (Figure 12). Containment of
flood flows within the leveed Atchafalaya system has eliminated the prolonged
overbank flooding in the outside areas.
The Courtableau study area receives water from an extensive agricultural
area north of U.S. Highway 190. This area is dewatered by Bayou Courtableau
which drains into the Fordouche area and also, to a minor extent, by water
flowing south into the Fausse Point Basin.
The Fausse Point Basin is located to the west of the Atchafalaya Basin
Floodway and receives water from the Courtableau area and from local drainage.
The area contains a large lake system including Dauterive Lake and Lake Fausse
Point (Figure 9). Agricultural activity is present in this area.
The Bayou Teche study area represents a unique area as it receives waters
draining from agricultural lands and water from the Atchafalaya Basin
Floodway. One station is located in Bayou Teche above the diversion canal
from the floodway, another is located south of the confluence of the diversion
canal and Bayou Teche, and the third in the diversion canal (Figure 10).
The Verret Basin located east of the Atchafalaya Floodway is contained
between the East Atchafalaya Floodway Protection levee and the natural levees
of the Mississippi River (Figure 12). Local precipitation is the only source
of water to the area. Agriculture exists within the Verret Basin, however,
such activity is much more limited than in the Fausse Point Basin. Sampling
stations are located in western segments of the Basin in Pat Bay, Lake Verret,
Grassy Lake, and Lake Palourde (Figures 9, 10, and 11).
Located within the Verret Basin, the Pat Bay area is a 45-km2 hydrological
unit that is well defined by natural and man-made boundaries (Figure 9). The
Pat Bay area was selected because, in comparison to areas within the
Atchafalaya Basin Floodway, Pat Bay experiences flooding episodes of local
precipitation origin which are generally short-lived. "Rainwater swamps" of
shallow depth and highly variable duration are formed within the Pat Bay area.
While some sections of this area experience prolonged inundation, a minor
relief appears to be sufficient to deter all but minimal exchange of the
shallow floodwaters with either permanent water bodies or substantial channel
systems. Water loss from the "rainwater swamps" is largely by
evapotranspiration.
36
-------
The study area south of Morgan City is characterized by extensive swamps,
canals and marshlands (Figure 12). The marshes and swamps have an intricate
tidal-drainage network dependent upon local runoff and tidal conditions. Two
areas contained within this area were examined, e.g., an industrial area and
Penchant Bayou area. The industrial area is located southeast of Morgan City
in the vicinity of the confluence of the Bayou Chene and Bayou Black
(Figure 11). The industrial complex present in this area includes ship and
oil rig construction and allied industries. The Bayou Penchant area
represents a unique area which receives water from both the Lower Atchafalaya
River and water draining from the Verret Basin.
The subareas of the Verret Basin (Pat Bay) and the area south of Morgan
City (industrial and Bayou Penchant) are presented on Figure 12 by dashed
lines. The Courtableau, industrial, south of Morgan City and Bayou Penchant
study areas are not distinct geographical areas as defined by natural
boundaries, but rather areas where sample collections were made.
Water entering the leveed Atchafalaya system is rich in nitrogen and
phosphorus content and is highly turbid, as indicated by a mean SECCHI value
of 6 in (15 cm) (Table 7). This river water is oxygen rich with a mean DO
content of 8.4 mg/1 and with the DOSAT at 85.
Comparison of inlet and outlet parameter mean values for the Basin Proper
reveals only a few differences. This is not particularly surprising when one
considers that approximately 85 percent of the Atchafalaya River water remains
intact as it flows through the Basin (Van Beek, In Press). However, SECCHI
radically changes from a mean of 6 in (15 cm) at the inlet to 17 in (43 cm) at
the outlet (Table 7). This change shows that a significant amount of
supsended material settles out as water passes through the Basin Proper. This
physical process would also account for the reduction of TP at the outlets as
compared to the inlets. OP means are generally higher in areas within the
leveed Atchafalaya system (63 ug/1) than at either the inlet (47 yg/1) or
outlet (44 ug/1). Transformation and utilization of both the TP and OP pools
must occur as water passes through the Basin.
The northern portions of the leveed Atchafalaya system represented by the
West Atchafalaya Floodway and Morganza Floodway above U.S. Highway 190 have
higher mean values for TP (270 and 343 yg/1, resectively) and TOC values (14.6
and 19.0 mg/1, respectively) than the Atchafalaya Basin Floodway exclusive of
Fordouche (southern portion of the system - TP, 176 ug/1. and TOC, 9.1 mg/1).
Mean SECCHI values are extremely low in the West Atchafalaya and Morganza
floodways [14 and 7 in (36 and 18 cm), respectively] and CHLA values are quite
low (7.8 and 7.4 yg/1 , respectively).
The Fordouche area is a unique area of the Atchafalaya Basin Floodway in
the fact that it receives water from the Courtableau area, the West Atchaflaya
Floodway above U.S. Highway 190, and Atchafalaya River water. Its resultant
chemical composition is therefore a mixture of the various sources. The mean
TP value for the area (219 yg/1) is the highest of any area within the Basin
Proper which is directly impacted by Atchafalaya River water, while its mean
DO level (4.9 mg/1) is the lowest recorded for any geographical area.

area. If there were less than 3 values for a parameter at a station,
-------
The amount of suspended material passing a given point in the Basin is
highly correlated with the total volume of water passing that point (USGS,
1977). In turn, deposition rates of suspended material are a function of the
amount of material in suspension, other factors being equal. Reduction in
flow rates associated with backwater swamp areas further favors deposition and
resulting loss of open water areas. Therefore, it is important to carefully
examine water quality in the eastern and western segments of the Atchafalaya
Basin Floodway because of the differences in the total amount of water they
receive per unit area.
The Buffalo Cove area is reresentative of the western segment while the
Upper Flats and the Upper Belle River areas would represent eastern segments
of the Floodway (Figure 12). The major chemical difference between these
areas is the mean ambient TP and OP levels (Table 7). The mean concentration
of TP in the Buffalo Cove area (203 yg/1) was approximately one and one-half
times the mean concentration of the Upper Flats (124 yg/1) area and one and
one-third times the mean for the Upper Belle River area (152 yg/1). Water has
to travel greater distances through backwater areas to reach the Upper Belle
River and the Upper Flats areas when compared to the Buffalo Cove area.
Reduction in flow rates associated with backwater areas favors depositions
with the resultant loss of TP from the water column. The lowest TP
concentration found in any of the geographical areas of the Basin was detected
in the Upper Flats area. Buffalo Cove and Upper Belle River areas had
elevated levels of inorganic nitrogen when compared to the Upper Flats area.
Only minor differences in other parameter values (TKJEL, DO, TOC, DOC, CHLA,
and SECCHI) were detected between the eastern and western segments of the
Atchafalaya Basin Floodway, exclusive of Fordouche. N-P ratios were extremely
low throughout all geographical areas of the Atchafalaya Basin and ranged from
1.1 to 5.7. In order to lower the potential for sediment deposition, flows
per unit area in the western segment of the Atchafalaya Basin Floodway could
be reduced to approximate those in the eastern segment without adversely
affecting environmental quality as long as the extent, duration, and depth of
natural flooding is maintained.
Areas both within and outside the leveed Atchafalaya system are rich in
nitrogen and phosphorus; they contain more than 190 yg/1 of mean TP and 400
yg/1 of inorganic nitrogen (Table 7). The most dramatic differences noted
between the areas are in mean CHLA concentrations and mean DOSAT. Mean CHLA
levels in the leveed Atchafalaya system were 8.5 yg/1 while the mean for
outside the system was 15.0 yg/1 (Table 7). The mean DOSAT was only 61 for
the inside system compared to 80 percent in the outside system. These
differences in mean DOSAT are related to the higher autotrophic production of
CHLA in the outer system.
SEASONAL DIFFERENCES
Parameter means for the 20 geographical areas were compared by seasons
(Appendix C). The seasons are defined as follows: winter (December 21 to
March 20), spring (March 21 to June 20), summer (June 21 to September 20), and
fall (September 21 to December 20).
39
-------
A number of trends emerge when examining the seasonal data for the leveed
Atchafalaya system (Table 8). The NH3N mean value dramatically rises during
the summer months when the mean TEMP value reaches its seasonal high. Mean
NH3N values during winter, spring, summer, and fall were 91, 73, 304, and 87
ug/1, respectively, while the mean TEMP values were 10.9, 21.2, 30.0, and
15.5, respectively. The TKJEL mean was also elevated during the summer, which
was basically due to the increase in the NH3N. However, the NO^NOsN mean was
highest in the spring, 370 yg/1 as compared to 280 ug/1 during fall, 268 ug/1
during summer, and 252 yg/1 during winter. Total nitrogen means (TKJEL and
N02N03N) are relatively high regardless of season; winter-954 ug/1, spring-
1122 ug/1, summer-1302 yg/l , and fal1-959 ug/1 The highest CHLA mean
occurred in the summer (15.4 ug/1) as compared to the means of 10.0 ug/1 for
fall, 6.0 ug/1 for spring, and 3.6 ug/1 for winter. DO means did not show the
same seasonal patterns as CHLA means, instead they varied as follows: fall-7.4
mg/1, winter-6.9 mg/1, summer-5.2 mg/1, and spring-4.6 mg/1. The DO mean was
the lowest during the spring when the Atchafalaya River flows were at their
maximum levels.

Light penetration, as measured by SECCHI, was low throughout the four
seasons of the year within the leveed Atchafalaya Basin system, although
probably due to different reasons. SECCHI measurements are basically governed
by suspended material. Suspended sediment loads generally increase as river
discharge increases and decrease as flows decrease (USGS, 1977). Suspended
material is composed of CHLA containing particles and non-chlorophyll a_
bearing particles. In the summer season, the CHLA mean was high and flows
were low, while in the spring the CHLA mean was low but flows were high. In
the fall, the CHLA mean was moderate and flows were relatively moderate. No
apparent differences were observed in SECCHI means between the four seasons.

-------
TP mean values did vary somewhat between seasons, however, all mean
seasonal values are relatively high. OP means are relatively high regardless
of season but the mean values are lower during the summer and fall seasons.
Mean N-P ratios were low (below 5) for all seasons.
The same basic seasonal trends which were described for the whole leveed
Atchfalaya system can be detected in any of the sub-geographical areas which
are contained within the leveed Atchafalaya Basin and are directly impacted by
the Atchafalaya River (Atchafalaya Basin Floodway including Fordouche, Upper
Belle River, Buffalo Cove, and Upper Flats). These trends can be summarized
as follows:
1) total nitrogen and TP levels are relatively high during all seasons,
2) the seasonal NH3N and CHLA concentrations dramatically increase in the
summer as compared to other seasons,
3) DO and autotrophic production trends do not follow the same seasonal
trends,
4) DO levels are generally depressed during the spring period when flows
are at their maximum levels, and
5) TOC levels are relatively constant during all seasons.
EFFECTS OF STAGE HEIGHT VARIATIONS
Discharge of the Atchafalaya River shows considerable variation, both
seasonally and annually (Figure 4). The average monthly discharge hydrography
at Simmesport for the period of 1963-1971 indicates the seasonal variation in
discharge rates for the Atchafalaya River. During the 9-year period, the
average discharge for the Atchafalaya River at Simmesport was 4,799 cms
(169,000 cfs). Discharges generally begin to increase in December and January
and Crest in the period between April and early June. Then they normally drop
off sharply to their seasonal lows in the late summer and early fall. The
cycle nature of discharge controls the annual regime of flooding for the
Atchafalaya Basin Floodway. A hydrograph for the Atchafalaya River at
Simmesport is presented in Figure 13 which encompasses the time frame in which
water samples were taken.
Data collected from the Atchafalaya Basin Floodway were divided into two
groups according to the discharge of the Atchafalaya River at Simmesport. One
group includes all data collected when the discharge of the Atchafalaya River
at Simmesport was above 4,799 cms (169,000 cfs) while the other group includes
all data below that discharge. Three separate periods were defined in which
the flows at some time during the period fell below 4,799 cms. Period I
occurred in 1974, period II occurred in 1975, and period III extended from the
summer of 1976 through the winter of 1977 (Figure 13). Data are presented for
high water and low water regimes for each eriod in Appendix D, followed by a
summary which combines the three periods and provides parameter mean values
for high and low water regimes for a given geographical area. However, no

data were collected in period II (1975) for the low water regime. Also, for
the low water regime during period I, only TEMP, pH, DO, SECCHI, and CHLA data
are available. Mean parameter values for period III are presented in Table 9
for high and low water regimes for geographical areas subjected to wide
fluctuations in stage height (i.e., the Atchafalaya Basin Floodway exclusive
of Fordouche, Fordouche, Buffalo Cove, Upper Flats, and Upper Belle River).
Generally, TP, OP, N02N03N and SECCHI mean parameter values are lower
during low water conditions than high water conditions, while the reverse is
true for DO, DOSAT, TEMP, TALK, NH3N, TKJEL, TOC, DOC, and POC. The Fordouche
area, which receives water basically from the Atchafalaya River and from water
entering through the Courtableau structure (located in the northwest corner of
the area), provides a number of exceptions to the above stated generalities.
Under low water conditions, a slight increase in the TP mean occurred (242
yg/1 compared to 228 yg/1) and the SECCHI remained the same as compared to the
high water regime. During low flows, this unit receives water only from the
Courtableau area and the West Atchafalaya Floodway which had higher TP
geographical means (229 and 270 ug/1) than other areas of the Atchafalaya
Basin Floodway. DO and TOC means were lower under the low water regime.
The reduction of flow rates during the low water regime enhances the
deposition of suspended materials with the resultant loss of a portion of TP
from the water column. The magnitude of the reduction of the TP means between
high and low water regimes is much greater for the Atchafalaya Basin Floodway,
Buffalo Cove, and Upper Belle River areas than the Upper Flats area. Water,
regardless of the stage height, must travel greater distances to reach the
Upper Flats area than the Buffalo Cove or Upper Belle River areas. Therefore,
a large proportion of TP may be lost through sedimentation before water enters
the Upper Flats area.
The reduction in TP under low water conditions probably does not reflect
the reduction in OP, but rather sedimentation of phosphorus-containing
suspensoids. The increased CHLA and NH3N levels suggest that the OP
reductions result from transformation to biological particulates.
DISSOLVED OXYGEN
Mean nutrient levels (TP and total nitrogen) within the Atchafalaya Basin
are great enough to support high levels of biological activity regardless of
geographical area, season, or water level. However, dissolved oxygen levels
can become critical in suporting the Basin's large populations of aquatic
life. Because of the above considerations, DO concentrations are one of the
most important gauges of the Basin's water quality and its ability to support
a well-balanced aquatic fauna.
Insufficient DO in the water column can cause fish kills and/or anaerobic
decomposition of organic material with concomitant releases of ammonia and
other noxious gases such as hydrogen sulfide. However, before the onset of
anaerobic conditions, DO levels become too low to provide for the maintenance
and well-being of the fish population as a whole.

-------
Many adult fish species can survive at low DO levels, even brook trout
have been acclimated to less than 2 mg/1 DO in the laboratory. The minimum
concentration necessary for continued existence of a varied fish population in
natural waters is not high. This minimum is not above 4 mg/1 and may be much
lower (National Academy of Science, 1973).
In considering DO levels, it is less important to know how long individual
fish can withstand low-oxygen waters than to consider the effects of such
conditions upon egg development, larval stages, normal growth and activity,
and successful completion of reproductive cycles. These factors are key to
the maintenance and well-being of the fishery resource as a whole.
Based upon extensive review of the available literature National Academy
of Science (1973) stated, "any reduction of dissolved oxygen can reduce the
efficiency of oxygen uptake by aquatic animals and hence reduce their ability
to meet demands of their environment." There is evidently no concentration
level or percentage of saturation to which the DO content of natural waters
can be reduced without causing or risking some adverse effects on the
reproduction, growth, and consequently the production of fishes inhabiting
those waters. However, through acclimation, avoidance of extremely low DO
conditions, and tolerance to short-term exposure, many species can survive
adverse DO conditions (Carlander, 1977). Accordingly, no single, arbitrary,
recommendation can be set for dissolved oxygen concentrations that will be
favorable for all kinds of fish in all kinds of waters, or even one kind of
fish in a single kind of water.
Fish do vary in their oxygen requirements by species, age, activity, and
temperature as the following examples for key fish species of the Atchafalaya
Basin illustrate. Critical levels of DO for largemouth bass at temperatures
from 25°C to 35°C ranged from 0.92 to 1.4 mg/1 in studies by Moss and Scott
(1961). However, Stewart et al., (1967) reported that food consumption and
food conversion to biomass are near their optimum at 7 and 5 mg/1
respectively, at 26°C. Largemouth bass avoid water with 1.5 mg/1 DO or less,
and show some avoidance at 3 to 4.5 mg/1 but do not avoid water at 6 mg/1 DO
at temperatures of 17°-22.5°C (Whitmore et al., 1960). Only when DO levels
are above 3.5 mg/1 did Dudley (1969) find largemouth embryo survival equal to
controls. The channel catfish seems to be more tolerant than either the
largemouth bass or the bluegill. They have been observed to survive at
concentrations of 0.97 mg/1 (Moss and Scott, 1961). However, Schmillon
(1970), observed channel catfish to die in cages at DO levels of 2 mg/1 at the
surface and 0.5 mg/1 at a depth of 3 feet. DO concentrations of 3.1 mg/1
during summer months and 0.8 mg/1 in the winter were found to be lethal to
bluegill (Moore, 1942). Also, Moore observed that all bluegill survived for
24 hours under summer conditions (23°C) at DO levels of 3.4 mg/1. While
crappie were found to avoid water where the DO was lower than 3.3 mg/1 in Lake
Texoma (Grinstead, 1969). Larimore (1957) found that the critical oxygen
tension (the concentration of DO at which oxygen consumption declines
abruptly) to be 3.6 mg/1 at 20°C for warmouth. While the various fish species
in the Atchafalaya Basin do not share a common DO level at which no
deleterious impact can be measured, almost all aquatic life will show some
impact of very low DO levels. National Academy of Science (1973) recomended a
47
-------
floor of 4 mg/1 except in situations where the natural level of DO is less
than 4 mg/1 and points out that the "black water" draining swamps of the
Southeastern United States naturally have low DO content.
DO levels of 2 and 4 mg/1 were selected to compare conditions which may be
detrimental to fish populations. The rationale for their respective selection
is that a level of 4 mg/1 or less maintained over a considerable period of
time will impact growth and development of fish especially largemouth bass and
white crappie, while a DO level of 2 mg/1 or less will increase the negative
impacts and can produce lethal conditions.
Appendix E presents the number of days mean DO concentrations were above
and below the selected values (2 and 4 mg/1) by season and water level for all
individual stations located within the Atchafalaya Basin Floodway including
the Fordouche area. Only data for the Atchafalaya Basin Floodway and its
subareas were included in Appendix E because the majority of the Basin's
fisheries resources are located there, and they are the most subject to low DO
concentrations. Appendix F presents DO daily means by station in mg/1, date
collected, and season for the Atchafalaya Basin Floodway and its subareas;
Buffalo Cove, Upper Flats, Upper Belle River, Grand Lake, and Fordouche.
Table 10 presents the ratio of the number of days mean DO concentrations
were below 2 and 4 mg/1 to the total number of days DO concentrations were
measured by season and selected geographical area. Seasons of the year are
designated as follows: winter (December 21 to March 20), spring (March 21 to
June 20), summer (June 21 to September 20), and fall (September 21 to December
20).
Within the Atchafalaya Basin Floodway, the majority of DO problems, as
defined by the 4 mg/1 level, occurred in the spring (39 percent or 77/194)
followed by the summer (29 percent or 19/164). Fall and winter seasons
contained a lower percent of problems (11 percent or 13/117 and 12/106,
respectively). The same general trend was observed for the following areas:
Buffalo Cove, Upper Flats, and Upper Belle River. The more severe DO
reductions (below 2 mg/1) were closely associated with the spring season.
Within the Atchafalaya Basin Floodway, 27 of 40 mean DO observations below 2
mg/1 occurred in the spring. No problems were detected within the Grand Lake
area which is greatly influenced by the oxygen-rich water of the Atchafalaya
River main stem.
As previously described, diversion of water per unit of area for the
western and eastern segments of the Atchafalaya Basin Floodway suggest that
the western segments receive roughly three times the amount of water as the
eastern segments (van Beek, et al., 1978). The Buffalo Cove area is
representative of the western segment while the Upper Flats and the Upper
Belle River areas represent eastern segments of the floodway. No differences
are apparent in the total percent of problems for these three areas at either
2 or 4 mg/1 DO level. At the 2 mg/1 DO level, the majority of the problems
occurred in the spring in the Buffalo Cove and Upper Belle River areas while
the Upper Flats experienced problems in the summer and spring.

* Atchafalaya Basin Floodway exclusive of Fordouche.
-------
Within the Fordouche area, problems as defined by the 4 mg/1 DO level,
basically occurred in the spring and summer. However, the more severe
problems as defined by the 2 mg/1 DO level were basically restricted to the
spring.
Table 11 presents the ratio of the number of days mean DO concentrations
were below 2 and 4 mg/1 to the total number of days DO concentrations were
measured by water level and selected geographical area. Water levels are
defined by a discharge of the Atchafalaya River at Simmesport of 4,799 cms
(162,500 cfs) or greater for high water and below this discharge level for low
water.
No differences are apparent in the percent of problems associated with
either high or low water at the 2 or 4 mg/1 DO values for the Atchafalaya
Basin Floodway, Buffalo Cove, or Fordouche areas. The percent of problems
which occurred at the 4 mg/1 DO level was nearly equivalent for the Upper
Flats and Upper Belle River areas for high and low water regimes. At the more
restricted value of 2 mg/1 DO, the Upper Flats experienced a higher percentage
of problems under low water conditions while the Upper Belle River area had a
higher percentage of problems under high water conditions.
Table 12 presents the ratio of the number days mean DO concentrations were
below 2 and 4 mg/1 to the total number of days DO concentrations were measured
by season and water level for the Atchafalaya Basin Floodway exclusive of
Fordouche. Water levels and seasons are used as previously defined.
Water levels are generally high in the Atchafalaya Basin Floodway during
the winter and spring, and therefore most of the DO samples were collected
during high water conditions for these seasons. However, in the winter water
levels rise and they generally reach their peak flows in the spring. The
flows then drop off sharply to their normal seasonal lows in late summer and
early fall. In the summer most of the DO samples were collected under low and
receding water conditions. Water levels are generally low but rising in the
fall and nearly an equal number of samples were collected for low and high
water conditions.
Two separate phenomena explain most of the conditions under which reduced
dissolved oxygen levels exist within the Atchafalaya Basin Floodway. One is
associated with high water levels when additional land areas containing
herbaceous materials and forest litter are being flooded or drained (fall and
spring, respectively). The other is associated with increased biological
activity and receding flows of the summer sason. Wells and Demas (1977) also
commonly found DO concentrations below 4.0 mg/1 in swamp areas during low flow
conditions when the water was warm.
During the fall, all of the DO problems were restricted to the high water
conditions, even though a proportional number of samples were collected under
high and low water conditions. This indicates that DO problems were not
associated with the water cycle when it receded to its annual low in early
fall but with the increased flows of late fall. Also, all DO problems were
restricted to the high water period in the winter season.

In the spring season the majority of the DO problems at either the 2 or 4
mg/1 levels occurred. In fact, the more severe problems, as defined by the 2
mg/1 DO level, are basically restricted to the spring season. Twenty-seven of
the 40 observations below the 2 mg/1 DO level were recorded in the spring with
21 of these observations being associated with high water.
Examination of station DO means (Appendix E) and unpublished data shows
that most of the extremely low DO concentrations during high water conditions
were at locations sheltered from extensive wind action or in areas with little
or no water circulation due to man-made or natural obstructions. Turbulence
at the water surface greatly increases the rate at which oxygen invades water
from the atmosphere and replenishes that lost to decomposition. It is
extremely important to provide for proper water circulation patterns in the
overflow areas of the Atchafalaya Basin Floodway during high water periods in
order to prevent large areas from having extremely low dissolved oxygen
concentrations which would adversely impact resident populations of aquatic
life.
The interaction of increased biological activity, as indicated by elevated
levels of CHLA and NH3N, and the reduced flows of oxygen-rich water apparently
produced the DO problems associated with the summer season.
ENERGY-NUTRIENT CYCLES
Comparisons of mean productivity, respiration, phytoplankton and CHLA
estimates, and carbon budgets, for areas inside and outside the leveed
Atchafalaya system, indicate that autotrophic food chains dominate areas
outside while bacteria-detritus food chains dominate those areas inside the
system which experience prolonged overbank flooding (Hern and Lambou, in
press). Earlier studies have also shown that these overflow areas have
characteristics of bacteria-detritus food chains (Lambou, 1961; Lambou, 1962).
The key to the high productivity of the Atchafalaya Basin Floodway is the
short, efficient, bacteria-detritus food chain. Given sufficient nutrients
(nitrogen and phosphorus) and adequate dissolved oxygen levels, carbon becomes
the lifeblood of this system. Prolonged overbank flooding, with the
inundation of additional land areas containing herbaceous material and forest
litter, renews the carbon resources needed to drive the bacteria-detritus
system.
Bacteria utilize both particulate and dissolved organic matter. They are
able to convert dissolved organic matter into particulate carbon (biomass)
which is then available as a more important food source to higher forms. In
addition to metabolizing the readily oxidizable forms of carbon (e.g. sugars,
starches), they are able to eventually convert even the more recalcitrant
forms of carbon (i.e. lignius, cellulose) into new biomass. Bacteria comprise
a large percentage of the nutritive value of detrital material. A typical
food chain in this system would be detritus to crawfish to largemouth bass.
The high productivity of the Atchafalaya Basin Floodway is not due primarily
to aquatic autotrophic production but rather to the bacteria-detritus food
chain.
53
-------
The organic compounds available for bacterial utilization which are
present in the aquatic system are both physically and chemically
heterogeneous. These organic constituents include a host of organic acids,
polysaccharides, lignins, aromatic and aliphatic hydrocarbons, sugars,
alcohols, ami no acids, purines, pyrimidines, proteins, lipids and nucleic
acids. The decomposition rate of organic materials is mainly dependent upon
the chemical compound while temperature, pH, oxygen supply, available minerals
and carbon:nitrogen ratios represent the chief environmental influences
(Alexander, 1961).
N-P ratios are very low in the Atchafalaya Basin (3:1, Table 3) and would
suggest severe nitrogen limitation for autotrophic production (Lambou et al.,
1976). However, both organic and inorganic forms of nitrogen and phosphorus
are biologically available to bacteria. Complete metabolism (mineralization)
of carbon (C6H1206 [% + ^0) at optimal rates by bacteria requires
carbon:nitrogen:phosphorus ratios of approximately 100:10:1 to 100:5:1
dependent upon bacterial community composition and environmental conditions
(Alexander, 1961). In addition, many of the constituents of the total organic
pool do not undergo rapid breakdown, e.g., lignins, cellulose and aromatic
hydrocarbons, and therefore do not represent a significant drain upon the
available nitrogen pool. Herbaceous material and leaf litter flooded during
high water stages in the Basin contain sufficient nitrogen to support their
breakdown by bacteria.
The mean nitrogen content of the Atchafalaya Basin waters which is
biologically available to bacteria is 1.218 mg/1 (0.905 pg/1 of TKJEL + 0.313
mg/1 of NO^NOsN) with total phosphorus in excess for bacteria metabolism (199
yg/1, Table 3). The amount of carbon which can be totally mineralized through
bacterial action, given the mean Basin nitrogen and phosphorus levels, becomes
a staggering 12 to 24 mg/1 while the mean total organic carbon content of the
Basin was only 10.6 mg/1. Sufficient nutrients, as indicated by the mean
concentration of total phosphorus and nitrogen, are available regardless of
the geographical area (Table 7), season (Table 8), or water level (Table 9)
for complete bacterial utilization of the total organic carbon contained
within the water column, even though Well and Demas (1977) state
"concentrations of nitrogen and phosphorus compounds in the Atchafalaya River
Basin are relatively low, generally less than 1,500 and 150 yg/1,
respectively."
A computer search of all station-date combinations where carbon:nitrogen
ratios exceeded 20:1 (100:5) for all stations contained within the Atchafalaya
Basin Floodway including the Fordouche area was conducted to reveal under what
environmental conditions nitrogen may be limiting. Only 5 of 470 possible
station-date combinations revealed carbon:nitrogen ratios greater than 20:1.
Another computer search was conducted to reveal all station-date
combinations where total phosphorus concentrations fell below 20 yg/1 for
stations contained within the Atchafalaya Basin Floodway including the
Fordouche area. This concentration of phosphorus would allow for optimal
rates of carbon breakdown by bacteria when 20 mg/1 of carbon is available. No
such station-date combinations were detected.
54
-------
Therefore, under the vast majority (99 percent) of the environmental
conditions found within the Atchafalaya Basin Floodway including the Fordouche
area, sufficient nitrogen and phosphorus is available for bacterial metabolism
of the organic carbon contained in the water column.
Naturally the processes involved in "largely autotrophic" and "largely
bacteria-detritus" systems are not mutually exclusive. The best estimate of
autotrophic system contributions to either bacteria-detritus or autotrophic
food chains is represented by CHLA levels. The CHLA mean for the Atchafalaya
Basin is approximately half (10 yg/1) of the mean for Louisiana lakes (19.3
yg/1) while the Atchafalaya Basin has higher TP and inorganic nitrogen mean
concentrations (Table 3). Therefore, the low of CHLA production cannot be
accounted for by low nitrogen and/or phosphorus levels. The apparent
discrepancy between high nutrients and low CHLA levels in the Atchafalaya
Basin is best addressed by examining SECCHI means. Light penetration, as
measured by SECCHI, was approximately twice as high in Louisiana lakes and
three times as high in southeastern lakes, on an average, as that in the
Atchafalaya Basin. This suggests light penetration as the cause of the low
CHLA production rather than low nutrient levels. The mean CHLA level in the
leveed Atchafalaya system was 8.5 yg/1 while the mean number of algal units
per mi Hi liter was nearly 35 times higher for waters outside the leveed system
than within (Hern et al., 1978).
Seasonal fluctuations of NH3N and DO are mediated by the bacteria-detritus
food chain within the leveed Atchafalaya system. The NH3N mean value
dramatically rises during the summer months when the mean temperature value
reaches its seasonal high. NH3N mean values of 91, 73, 304, and 87 yg/1 were
calculated for winter, spring, summer, and fall, respectively while mean
temperatures of 10.9, 21.2, 30.0, and 15.5 were recorded for the same
respective seasons (Table 8). The NH3N rise is probably due to increased
bacterial action primarily associated with the bottom sediments during the
warmer summer months.
The highest CHLA mean occurred in the summer (15.4 yg/1) as compared to
means of 10.0 yg/1 for fall, 6.0 yg/1 for spring, and 3.6 yg/1 for winter.
One would expect the highest seasonal mean of dissolved oxygen during the
summer season, when the highest autotrophic production, as indicated by CHLA
levels, occurred. However, the second lowest seasonal DO mean (5.2 mg/1) was
recorded during the summer season (Table 8). This is probably indicative of
the increased oxygen requirements for bacterial metabolism associated with the
bottom sediments in the warmer months. The lowest dissolved oxygen mean (4.6
mg/1) occurred in the spring when flows and stage heights normally reach their
maxima. Associated with the spring increase of flows and stage heights are
the inundation of areas containing new vegetation, leaf litter of the previous
season(s), and other allocthonous inputs. These additional sources of carbon
stimulate bacterial action with a resultant decrease in the mean DO
concentration during the spring. By comparison, highest seasonal means for DO
occurred in the fall and winter, 7.4 and 6.9 mg/1, respectively.
Manifestations of the bacteria-detritus food chain in those areas which
are impacted by prolonged overbank flooding, e.g. the Atchafalaya Basin
Floodway (exclusive of Fordouche), Fordouche, Upper Flats, Upper Belle River,
55
-------
and Buffalo Cove reflect nutrient variation in relation to water level
fluctuations. Under low water conditions, OP and N02N03N mean values are
reduced while CHLA, TEMP, N^N, TKJEL, TOC, and DOC means increase relative to
high water levels (Table 9). Increased bacterial and phytoplankton activity,
as indicated by elevated means for DOC, NH3N, and CHLA occurs with the higher
temperatures associated with low water levels. The increased biological
activity associated with low water periods may account for the corresponding
reduction in OP and N02N03N.
A strong case has been made to support the fact that nutrients (nitrogen
and phosphorus) are available at levels more than sufficient to support
bacterial breakdown of organic matter found within the waters of the
Atchafalaya Basin Floodway regardless of season, geographical area, or water
level, and that major differences in the nature and level of productivity
(e.g., bacteria-detritus vice autotrophic production) are mediated by the
regimes of periodic overflow. However, the overflow type of regimes now
existing must be maintained in the Atchafalaya Basin Floodway in order to
maintain the bacteria-detritus food chain upon which the high productivity of
aquatic life is dependent.

APPENDIX B. GEOGRAPHICAL MEANS
This appendix was generated by computer. Because of this it was necessary
to print alphabetic characters in upper case without subscripts, and parameter
values are given to 8 decimal places. Parameter means are presented for 20
geographical areas of the Atchafalaya Basin with the number of stations
located within the area (N), standard deviation of the geographical mean, and
minimum and maximum station means. The 20 geographical areas consist of the
leveed Atchafalaya system, West Atchafalaya Floodway, Morganza Floodway,
Fordouche, Atchafalaya Basin Floodway exclusive of Fordouche, Upper Flats,
Buffalo Cove, Upper Belle River, Grand Lake, inlet, outlet, outside leveed
Atchafalaya system, Courtableau, Fausse Point Basin exclusive of Bayou Teche,
Bayou Teche, south of Morgan City, industrial area, Bayou Penchant, Verret
Basin, and Pat Bay. These areas are described in the section of the report
entitled Geographical Differences.
Values for TP, OP, NH3, N02N03N, TALK, TKJEL, DO, TOC, DOC and POC are
given in mg/1; TEMP is given in degrees Celsius; PH in standard units; SECCHI
in inches; CHLA in ug/1; and DOSAT in percent, while N-P is a unitless ratio.

APPENDIX C. PARAMETER MEANS BY SEASON FOR GEOGRAPHICAL
AREAS OF THE ATCHAFALAYA BASIN
This appendix was generated by computer. Because of this it was necessary
to print alphabetic characters in upper case without subscripts and parameter
values are given to 8 decimal places. Seasonal means for 20 geographical
areas of the Atchafalaya Basin are presented with the number of stations
sampled (N), standard deviations of the means, minimum and maximum station
means. Seasons of the year are designated as follows; season 1 = winter
(December 21 to March 20), season 2 = spring (March 21 to June 20), season 3 =
summer (June 21 to September 20), and season 4 = fall (September 21 to
December 20). The 20 geographical areas consist of the leveed Atchafalaya
system, West Atchafalaya Floodway, Morganza Floodway, Fordouche, Atchafalaya
Basin Floodway exclusive of Fordouche, Upper Flats, Buffalo Cove, Upper Belle
River, Grand Lake, inlet, outlet, outside the leveed Atchafalaya system,
Courtableau, Fausse Point Basin exclusive of Bayou Teche, Bayou Teche, south
of Morgan City, industrial area, Bayou Penchant, Verret Basin, and Pat Bay.
These areas are described in the section of the report entitled Geographical
Differences.
Values for TP, OP, NH3N, N02N03N, TALK, TKJEL, DO, TOC, DOC and POC are
given in mg/1; TEMP is given in degrees Celsius; PH in standard units; SECCHI
in inches; CHLA in ug/1; DOSAT in percent, while N-P is a unitless ratio.

APPENDIX D. PARAMETER MEANS BY WATER LEVEL FOR
SELECTED AREAS OF THE ATCHAFALAYA BASIN
This appendix was generated by computer. Because of this it was necessary
to print alphabetic characters in upper case without subscripts and parameter
values are given to eight decimal places. Water level means (high and low)
are presented by time periods for selected areas of the Atchafalaya Basin,
with the number of stations sampled (N), standard deviations of the means, and
minimum and maximum station means. The Atchafalaya Basin Floodway exclusive
of Fordouche, Fordouche, Buffalo Cove, Upper Flats, and Upper Belle River were
selected because they are subjected to wide fluctuations in water stage
heights.
High water is defined as when the Atchafalaya River at Simmesport has a
discharge rate equal or above 4,799 cms (169,500 cfs). The selected discharge
rate is the 9-year (1963-1971) average discharge of the Atchafalaya River at
Simmesport. Time periods are abbreviated and defined as follows: PER I =
period I (1974), PER II = period II (1975), and PER III = January 1976 to July
1977. The data are organized by high and low water periods I, II and III for
selected geographical areas. This is followed by a summary of all high and
low water levels for the given area.
Values for TP, OP, NH3N, N02N03N, TALK, TKJEL, DO, TOC, DOC and POC are
given in mg/1; TEMP is given in degrees Celsius; PH in standard units; SECCHI
in inches; CHLA in pg/1; DOSAT in percent, while N-P is a unitless ratio.

APPENDIX E. THE NUMBER OF DAYS MEAN DO CONCENTRATIONS WERE ABOVE AND
BELOW 2 OR 4 MG/L OF DISSOLVED OXYGEN BY SEASON AND WATER LEVEL
FOR STATIONS IN THE ATCHAFALAYA BASIN FLOODWAY
This appendix was generated by computer. Because of this it was
necessary to print alphabetic characters in upper case. The number of days
mean DO observations were above and below 2 and 4 mg/1 is presented by season
and water level for stations located within the Atchafalaya Basin Floodway.
The percent of the number of observations below 2 and 4 mg/1 of dissolved
oxygen is presented in parenthesis.
Seasons of the year are defined as winter (December 21 to March 20),
spring (March 21 to June 20), summer (June 21 to September 20), and fall
(September 21 to December 20). High water is defined as when the Atchafalaya
River at Simmesport has a discharge rate equal or above 4,799 cms (169,500
cfs), while low water is defined by a discharge rate of less than 4,799 cms
(169,500 cfs).

APPENDIX F. IAN DISSOLVED OXYGEN CONCENTRATIONS FOR STATIONS
LOCATED IN THE ATCHAFALAYA BASIN FLOODWAY
This appendix was generated by computer. Because of this it was necessary
to print alphabetic characters in upper case. This appendix lists mean
station DO observations in mg/1 by date collected and season for the
Atchafalaya Basin Floodway exclusive of Fordouche and its subareas: Buffalo
Cove, Upper Flats, Upper Belle River, Grand Lake, and Fordouche. These areas
of the Basin were selected because they are subjected to prolonged overbank
flooding. The heading in capital letters designates the geographical areas,
e.g., FORDOUCHE. Column 1 under the geographical area defines the station,
column 2 lists the date the station was sampled, column 3 lists the season the
station was sampled and column 4 presents the mean station DO concentrations
in mg/1 for the given date. Seasons are defined as 1 = winter (December 21 to
March 20), 2 = spring (March 21 to June 20), 3 = summer (June 21 to September
20), and 4 = fal1 (September 21 to December 20).

6. ABSTRACT
his report describes water quality in the Atchafalaya Basin in terms of geographical
areas, seasonal patterns, and its relationships to water regimes and compares water
quality in the Basin to water quality in other Louisiana and southeastern lakes.
[mphasis in this report is given to water quality in the Atchafalaya Basin Floodway,
.e., that portion of the Atchafalaya Basin subject to frequent and prolonged natural
>verbank flooding and most subjected to hydrological modifications by man. The key to
the high productivity of the Floodway is the short, efficient, bacteria-detritus food
chain. Organic matter processed through bacterial metabolism represents the
:oundation of the system. Nitrogen and phosphorus levels are sufficient for bacterial
netabolism of organic matter, regardless of geographical area, season, or water level.
rolonged overbank flooding, with the inundation of additional land areas containing
lerbaceous material and forest litter, renews the carbon resources needed to drive the
>acteria-detritus system. It is recommended that to maintain the highly efficient
>acteria-detritus food chain, the extent, duration, and depth of natural flooding
nust be maintained to the greatest degree possible.
