A COMPENDIUM OF LAKE AND RESERVOIR
DATA COLLECTED BY THE NATIONAL
EUTROPHICATION SURVEY IN THE
CENTRAL UNITED STATES
WORKING PAPER NO. 476
September, 1978
-------
INTRODUCTION
The National Eutrophication Survey (NES) was initiated in 1972 by
the U.S. Environmental Protection Agency (EPA) to investigate the nation-
wide threat of accelerated eutrophication to freshwater lakes and reser-
voirs. In conjunction with State environmental agencies, the Survey
developed information on nutrient sources, inputs, and impacts on select-
ed freshwater lakes and reservoirs throughout the contiguous United
States. In total, over 800 lakes and reservoirs, 4,200 tributaries and
lake outlets, and 1,000 sewage treatment plants were included in the
sampling programs which involved a joint field effort by EPA personnel,
the National Guard of each State, operators of municipal and industrial
waste treatment plants, and personnel of the respective State agency
responsible for water pollution control activities. For details of the
procedures and methods used in the geographical area encompassed in this
report, refer to NES Working Paper No. 175,, “National Eutrophication
Survey Methods, 1973-1976”.
One of the primary outputs of the NES program is the individual
lake or reservoir report in which are summarized the trophic condition;
the nutrient sources, loads, and controllability; and the limiting
nutrient. Each report also includes all of the NES data pertaining to
the water body, the drainage area, and the nutrient point sources. To
make the NES data accessible to many users, data in each lake report
have been summarized and compiled in this report which includes informa-
tion on the water bodies sampled during the third year of the Survey
-------
2
(1974). Geographically, this compendium includes data on lakes and
reservoirs in Arkansas, Iowa, Kansas, Louisiana, Missouri, Nebraska,
North Dakota, Oklahoma, South Dakota, and Texas.
Compendia of data on water bodies in other areas of the U.S. have
been prepared. Working Paper No. 474 includes data on water bodies
sampled in 1972 (northeast and part of north-central U.S.); Working
Paper No. 475 provides data on water bodies sampled in 1973 (east, north-
central, and southeastern States); and Working Paper No. 477 includes
the data obtained in 1975 (Rocky Mountain and far-western States).
COMPENDIUM COMPONENTS
In the compendium heading for each water body, the identifiers are
given (NAME, STATE, principal COUNTY, STORET NO., WORKING PAPER NO., and
NTIS ACCESSION NO.). Following the NAME, the trophic condition of the
water body is shown in parentheses.
The trophic condition is based on an assessment of the data collected
during the sampling year supplemented by results of past stucli.es, if
any, and communications with State personnel. Each water body was
categorized as “OLIGOTROPHIC” (low nutrient levels and productivity),
“MESOTROPHIC” (moderate nutrient levels and productivity), “EUTROPHIC
(high nutrient levels and productivity), or “HYPEREUTROPHIC” (very high
nutrient levels and productivity). For large water bodies, two or more
trophic categories maybe indicated; e.g. , the major tributary embayments
(nearest the nutrient sources) may be eutrophic while the main portion
of the water body is mesotrophic.
-------

Following the heading, the data are arranged in five categories:
I. MORPHOMETRY
II. PHYSICAL AND CHEMICAL CHARACTERISTICS
III. BIOLOGICAL CHARACTERISTICS
IV. NUTRIENT LOADING CHARACTERISTICS
V. NON-POINT SOURCE NUTRIENT EXPORT
Each of these categories contains related information as discussed
below. If data were not obtained, a series of asterisks is shown.
I. MORPHOMETRY
The morphometric data were compiled from the literature and/or from
information provided by State and Federal personnel.
LAKE TYPE - either of NATURAL origin or resulting from stream
IMPOUNDMENT.
DRAINAGE AREA (SQ KM) - the total drainage area (measured to the
outlet) in square kilometers.
SURFACE AREA (SQ KM) - the area of the water surface in square
kilometers.
MEAN DEPTH (METERS) - the volume of the water body, in cubic meters,
divided by the surface area in square meters.
TOTAL INFLOW (CMS) - the mean of the inflows of all tributaries and
the immediate drainage in cubic meters per second.
RETENTION TIME (YEARS or DAYS) - a mean value determined by divid-
ing the lake volume, in cubic meters, by the mean annual
outflow in cubic meters per unit of time. Note that the
outflow maybe less than the total inflow because of evapora-
tion; withdrawals for irrigation, public water supply, or
other uses are included in the outflow.
II. PHYSICAL AND CHEMICAL CHARACTERISTICS
These data are based on the sampling of each water body in the
spring, summer, and fall of 1974. Depending on size, from one to many
-------
4
sites were sampled, and multiple depths usually were sampled at each
site. For every parameter in this category, except Secchi disc depth,
the median value is reported. The median represents the middle value of
all sampling stations, times, and depths. The mean of the SECCHI DISC
depths at all stations and all sampling times is given.
MEDIAN ALKALINITY (MG/L) - total alkalinity, as CaCO 3 , in milligrams
per liter.
MEDIAN CONDUCTIVITY (IJMHOS) - specific conductance at 25°C in
micromhos per centimeter.
MEAN SECCHI DISC (METERS) - the mean limit of visibility of a
standard Secchi disc in meters.
MEDIAN TOTAL PHOSPHORUS (MG/L) - as P in milligrams per liter.
MEDIAN DISSOLVED PHOSPHORUS (MG/L) - as P in milligrams per liter.
MEDIAN INORGANIC NITROGEN (MG/L) - nitrate + nitrite + ammonia, as
N, in milligrams per liter.
MEDIAN TOTAL NITROGEN (MG/L) - Kjeldahl nitrogen + nitrate +
nitrite, as N.
III. BIOLOGICAL CHARACTERISTICS
MEAN CHLOROPHYLL A (UG/L) - the mean concentration of all samples,
in micrograms per liter.
ALGAL ASSAY CONTROL YIELDS (MG/L-DRY WT) - for many of the water
bodies are based on values, in milligrams per liter dry weight,
obtained from samples collected during the first (spring) and
last (fall) samplings. The values shown represent the range
of yields, and the number following in parentheses indicates
the number of samples assayed. The test organism was
Selenastrum capricornutum Printz.
LIMITING NUTRIENT (no units) - may be determined by two procedures
which are (1) the growth response of Selenastrum capricornutum
to the addition of various amounts of phosphorus or nitrogen
or (2) the ratio of inorganic nitrogen to dissolved phosphorus
determined from the sampling data. When the inorganic nitrogen
-------
5
to dissolved phosphorus ratio is 14/1 or greater, the water
body is considered phosphorus limited, whereas ratios of less
than 14/1 are considered indicative of nitrogen limitation.
The LIMITING NUTRIENT at each sampling time is given. Except for
the first and last sampling dates, the limiting nutrient is based on the
N/P ratio. The limiting nutrient for the first and last sampling date
generally is based on algal assay results. However, if no value is shown
for the ALGAL ASSAY CONTROL YIELD, the limiting nutrient for those dates
is determined by the N/P ratio. Where “ND” is shown, nutrient data were
not obtained, and the limiting nutrient cannot be determined.
SUMMARY OF PHYTOPLANKTON DATA - the COUNT of individuals, filaments,
or colonies per milliliter of sample for each of the five most
numerous genera on the date shown. The sum of the units of
other genera present in the sample, but not specified, is also
included.
IV. NUTRIENT LOADING CHARACTERISTICS
Nutrient loads of significant tributaries and the water body out-
let(s) were calculated using the results of analyses of from 12 to 14
samples collected from each stream by the State National Guard monthly
for a one-year period and stream flow estimates as provided by the U.S.
Geological Survey through an interagency agreement. The nutrient loads
of the unsampled portion of the drainage areas were estimated from the
measured nutrient loads in the sampled streams in the area. Nutrient
loads of all streams and the unsampled drainage area were estimated on
the basis of a year of average or “normal” stream flow to minimize the
influence of extreme hydrological events that may have occurred during
the sampling year.
-------
6
Sewage treatment plant nutrient loads were determined from results
of analyses of from 5 to 14 monthly effluent samples and corresponding
flow data provided by plant operators or by State agency personnel. For
sewage treatment plants which were not sampled and those from which
fewer than five samples were received, nutrient discharges were esti-
mated on the basis of the population served by the facility.
For details of sampling procedures and methods of calculation,
refer to NES Working Paper No. 175.
A. INPUT - an estimate of all external inputs of nitrogen and
phosphorus to the water body.
POINT SOURCE MUNICIPAL (KG/YR) - an estimate of annual nitrogen and
phosphorus inputs from municipal sewage treatment plants in
kilograms per year.
POINT SOURCE INDUSTRIAL (KG/YR) - an estimate of annual nitrogen
and phosphorus inputs from industrial waste treatment plants
in kilograms per year.
POINT SOURCE SEPTIC TANKS (KG/YR) - an estimate of annual nitrogen
and phosphorus inputs from septic tanks within approximately
90 meters of the shoreline in kilograms per year. If a value
is shown for nitrogen but not phosphorus, the estimated phos-
phorus input was less than 5 kg.
NON-POINT SOURCE (KG/YR) - an estimate of the annual nitrogen and
phosphorus inputs from tributaries, immediate drainage, and
precipitation in kilograms per year.
TOTAL LOADING (KG/YR) - the sum of all external nitrogen and phos-
phorus inputs.
LAKE SURFACE AREA LOADING RATE (GISQ M/YR) - the total loading for
the sampling year divided by the lake surface area
( k /. r x 1O- ) in grams per square meter of surface area per
year.
B. OUTPUT - an estimate of the annual nitrogen and phosphorus
discharged through the lake OUTLET(S) (KG/YR) in kilograms per
year. Asterisks indicate little or no outlet flow (and output)
during the sampling year.
-------
7
PERCENT RETENTION - the percentage of incoming nitrogen or phospho-
rus retained in the lake annually:
( Input load-output load 100%’
input load
V. NON-POINT SOURCE NUTRIENT EXPORT
STREAM NAME -
MEAN FLOW (CMS) - the mean stream flow in a year of average hydrol-
ogy in cubic meters per second.
DRAINAGE AREA (SQ KM) - the drainage area of the stream in square
kilometers.
MEAN TOTAL P (MG/L) - the mean concentration of total phosphorus in
the stream at the sampling site during the year of sampling.
MEAN TOTAL N (MG/L) - the mean concentration of total nitrogen in
the stream at the sampling site during the year of sampling.
TOTAL P EXPORT (KG/SQ KM/YR) - the total phosphorus load of the
stream (after subtracting known point-source loads) divided by
the drainage area, in kilograms per square kilometer per year.
Asterisks indicate the phosphorus was less than 0.1 kg if a
value is shown for nitrogen.
TOTAL N EXPORT (KG/SQ KM/YR) - the total nitrogen load of the
stream (after subtracting known point-source loads) divided by
the drainage area, in kilograms per square kilometer per year.
