FOREWORD
The National Eutrophication Survey was initiated in 1972 in
response to an Administration commitment to investigate the nation-
wide threat of accelerated eutrophication to freshwater lakes and
reservoirs.
OBJECTIVES
The Survey was designed to develop, in conjunction with state
environmental agencies, information on nutrient sources, concentrations,
and impact on selected freshwater lakes as a basis for formulating
comprehensive and coordinated national, regional, and state management
practices relating to point-source discharge reduction and non-point
source pollution abatement in lake watersheds.
ANALYTIC APPROACH
The mathematical and statistical procedures selected for the
Survey's eutrophication analysis are based on related concepts that:
a. A generalized representation or model relating
sources, concentrations, and impacts can be constructed.
b. By applying measurements of relevant parameters
associated with lake degradation, the generalized model
can be transformed into an operational representation of
a lake, its drainage basin, and related nutrients.
c. With such a transformation, an assessment of the
potential for eutrophication control can be made.
LAKE ANALYSIS
In this report, the first stage of evaluation of lake and water-
shed data collected from the study lake and its drainage basin is
documented. The report is formatted to provide state environmental
agencies with specific information for basin planning [§303(e)], water
quality criteria/standards review [§303(c)], clean lakes [§314(a,b)],
and water quality monitoring [§106 and §305(b)] activities mandated
by the Federal Water Pollution Control Act Amendments of 1972.
-------
m
Beyond the single lake analysis, broader based correlations
between nutrient concentrations (and loading) and trophic condi-
tion are being made to advance the rationale and data base for
refinement of nutrient water quality criteria for the Nation's
fresh water lakes. Likewise, multivariate evaluations for the
relationships between land use, nutrient export, and trophic
condition, by lake class or use, are being developed to assist
in the formulation of planning guidelines and policies by EPA
and to augment plans implementation by the states.
ACKNOWLEDGEMENT
The staff of the National Eutrophication Survey (Office of
Research & Development', U. S. Environmental Protection Agency)
expresses sincere appreciation to the Texas Water Quality Board
for professional involvement, to the Texas National Guard for
conducting the tributary sampling phase of the Survey, and to
those Texas wastewater treatment plant operators who voluntarily
provided effluent samples.
Hugh C. Yantis, Jr., Executive Director of the Texas Water
Quality Board, and John B. Latchford, Jr., Director, and the staff
of the Field Operations Division provided invaluable lake documen-
tation and counsel during the Survey, reviewed the preliminary
reports, and provided critiques most useful in the preparation of
this Working Paper series.
Major General Thomas Bishop, the Adjutant General of Texas,
and Project Officer Colonel William L. Seals, who directed the
volunteer efforts of the Texas National Guardsmen, are also grate-
fully acknowledged for their assistance to the Survey.

I. CONCLUSIONS
A. Trophic Condition:
Survey data indicate that Lake Kemp is eutrophic; i.e.,
well supplied with nutrients and quite productive. Whether
nutrient enrichment is beneficial or deleterious depends on
the actual or potential effect on the uses of the lake. In
this regard, no nuisance conditions are known to personnel
of the Texas Water Quality Board and there is little or no
impairment of the designated beneficial uses of this water
body.
Lake Kemp ranked fourth in overall trophic quality when the
39 Texas reservoirs sampled in 1974 were compared using a combi-
nation of six parameters*. Nine of the reservoirs had less and
one had the same median total phosphorus, two had less and five
had the same median dissolved orthophosphorus, 14 had less and
two had the same median inorganic nitrogen, 17 had less mean
chlorophyll eu and 17 had greater mean Secchi disc transparency.
Moderate depression of dissolved oxygen with depth occurred at
sampling stations 1 and 2 in August.
Survey limnologists noted turbidity due to suspension of red
clay bottom materials in March and October. Blue-green algae
were dominant in the August and October phytoplankton samples
(page 8).
* See Appendix A.
-------
B. Rate-Limiting Nutrient:
The algal assay results indicate that the lake was phosphorus
limited at the time the sample was collected. The lake data
indicated phosphorus limitation in March, May, and August but
nitrogen limitation in October.
C. Nutrient Controllability:
1. Point sources—No known municipal or industrial point
sources impacted Lake Kemp during the sampling year. It is
estimated that septic tanks serving lakeshore dwellings contrib-
uted less than 2% of the total phosphorus load to the lake, but
a shoreline survey would be necessary to determine the signifi-
cance of these sources.
It is calculated that Lake Kemp received a total phosphorus
loading of 0.20 g/m2/yr. This is less than that proposed by
Vollenweider (Vollenweider and Dillon, 1974) as a eutrophic loading
but is more than his suggested oligotrophic loading (i.e., a meso-
trophic loading; see page 14). However, U.S. Geological Survey
records for water year 1975 (Anonymous, 1976) show the volume of
Lake Kemp during the year was less than 60% of the conservation
pool volume, so the actual areal phosphorus loading was greater
than indicated.
2. Non-point sources—The phosphorus contribution of non-
point sources accounted for about 98% of the total phosphorus
load during the sampling year. The Wichita River contributed
-------
over 83% of the total, and the minor tributaries and immediate
drainage were estimated to have contributed about 6%.
The phosphorus export rate of the Wichita River was a
rather low 2 kg/km2/yr. This rate is comparable to the rates
of unimpacted streams sampled elsewhere in Texas.

III. WATER QUALITY SUMMARY
Lake Kemp was sampled four times in 1974 by means of a pontoon-
equipped Huey helicopter. Each time, samples for physical and chemical
parameters were collected from two or more depths at three stations on
the lake (see map, page vi). During each visit, a single depth-integrated
(4.6 m or near bottom to surface) sample was composited from the stations
for phytoplankton identification and enumeration; and during the first
visit, a single 18.9-liter depth-integrated sample was composited for
algal assays. Also each time, a depth-integrated sample was collected
from each of the stations for chlorophyll a^ analysis. The maximum depths
sampled were 13.1 meters at station 1, 10.4 meters at station 2, 1.8
meters at station 3, and 7.0 meters at station 4.
The sampling results are presented in full in Appendix D and are
summarized in the following table.

of Lake Kemp was low at the time the assay sample was col-
lected (03/04/74). Also, a significant increase in yield
with the addition of phosphorus alone indicates that the
lake was phosphorus limited at that time. Note that the
addition of nitrogen alone resulted in a yield no greater
than that of the control.
The lake data indicate phosphorus limitation in March,
May, and August but nitrogen limitation in October (the mean
inorganic nitrogen to orthophosphorus ratios were 16 to 1,
24 to 1, 38 to 1, and 4 to 1, respectively).

IV. NUTRIENT LOADINGS
(See Appendix E for data)
For the determination of nutrient loadings, the Texas National
Guard collected monthly near-surface grab samples when possible from
each of the tributary sites indicated on the map (page vi), except for
the months of April and May when two samples were collected at the inlet.
Sampling was begun in September, 1974, and was completed in August, 1975.
Through an interagency agreement, stream flow estimates for the
year of sampling and a "normalized" or average year were provided by
the Texas District Office of the U.S. Geological Survey for the
tributary sites nearest the lake.
In this report, nutrient loads for sampled tributaries were calculated
using mean annual concentrations and mean annual flows. Nutrient loads
for unsampled "minor tributaries and immediate drainage" ("II" of U.S.G.S.)
were estimated using the mean concentrations in Wichita River at station
A-2 and the mean annual II flow.
No known point sources impacted Lake Kemp during the sampling year.

E. Yearly Loads:
In the following table, the existing phosphorus loadings
are compared to those proposed by Vollenweider (Vollenweider
and Dillon, 1974). Essentially, his "dangerous" loading is
one at which the receiving water would become eutrophic or
remain eutrophic; his "permissible" loading is that which
would result in the receiving water remaining oligotrophic
or becoming oligotrophic if morphometry permitted. A meso-
trophic loading would be considered one between "dangerous"
and "permissible".
Note that Vollenweider's model may not be applicable to
water bodies with short hydraulic retention times.
