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 fresh water 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)j, 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.
-------
iii
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.
ACKNOWLEDGMENT
The staff of the National Eutrophication Survey (Office of
Research & Development, U. S. Environmental Protection Agency)
expresses sincere appreciation to the Ohio Environmental Protection
Agency for professional involvement, to the Ohio National Guard
for conducting the tributary sampling phase of the Survey, and to
those Ohio wastewater treatment plant operators who provided
effluent samples and flow data.
Ned Williams, Director, and Tom Birch, Ken Carr, Larry
Dietrick, Ron Havlice, Larry Korecko, Rod Mehlhop, Terry Wheeler,
and John Youger, Ohio Environmental Protection Agency, provided
invaluable lake documentation and counsel during the Survey,
reviewed the preliminary reports, and provided critiques most
useful in the preparation of this Working Paper series.
Major General Dana L. Stewart, then the Adjutant General
of Ohio, and Project Officer Lt. Colonel Robert C. Timmons,
who directed the volunteer efforts of the Ohio National Guards-
men, are also gratefully acknowledged for their assistance to
the Survey.

I. CONCLUSIONS
A. Trophic Condition:
Survey data indicate that Hoover Reservoir is eutrophic.
It ranked fifth in overall trophic quality when the 20 Ohio
lakes sampled in 1973 were compared using a combination of
six parameters*. Two of the lakes had less and one had the
same median total phosphorus, four had less median dissolved
phosphorus, 14 had less inorganic nitrogen, four had less
mean chlorophyll a_, and two had greater Secchi disc transpar-
ency. Depression of dissolved oxygen with depth occurred at
three of the four sampling stations in August and October.
Survey limnologists noted concentrations of algae at two
of the four sampling sites in April.
B. Rate-Limiting Nutrient:
The algal assay results indicate that the primary produc-
tivity in Hoover Reservoir was limited by phosphorus at the
time the sample was taken (04/26/73). The lake data indicate
phosphorus limitation at the other sampling times as well.
C. Nutrient Controllability:
1. Point sources—During the sampling year, known point
sources accounted for 27.5% of the total phosphorus load reach-
ing Hoover Reservoir. The wastewater treatment plant at Sunbury
* See Appendix A.
-------
contributed 14.3%, Walnut Bluffs contributed 4.8%, Lake
Estates contributed 2.7%, and the Bonanza Mobile Home Park
contributed 2.5% of this total. The town of Galena is esti-
mated to have contributed 3.2%.
Two industrial point sources of probable nutrient signif-
icance discharge to Big Walnut Creek (Youger, 1975). No
information is available on the nutrient contributions of
these sources; however, the loads are included in those meas-
ured in the creek at station A-l.
The present phosphorus loading of 1.74 g/m2/yr is more
than two times that proposed by Vollenweider (Vollenweider
and Dillon, 1974) as a eutrophic loading (see page 12). Because
the reservoir is phosphorus limited, all phosphorus inputs
should be minimized to the greatest practicable extent to slow
the eutrophication now occurring in Hoover Reservoir.
2. Non-point sources--Non-point sources accounted for 72.5%
of the total phosphorus load. Big Walnut Creek contributed
44.9%, Little Walnut Creek contributed 11.7%, and Duncan Run
contributed 4.9% of the total. Ungaged tributaries were
estimated to have contributed 10.0% of the total phosphorus
input.
The phosphorus export rate of Big Walnut Creek was a little
higher than the rates of the other two sampled tributaries (see
page 12). The higher rate may be due to the unmeasured industrial
point sources noted above.

III. LAKE WATER QUALITY SUMMARY
Hoover Reservoir was sampled three times during the open-water
season of 1973 by means of a pontoon-equipped Huey helicopter. Each
time, samples for physical and chemical parameters were collected
from four stations on the lake and from a number of depths at each
station (see map, page v). 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 17.7 meters at station 1, 15.2 meters at station 2,
10.7 meters at station 3, and 3.4 meters at station 4.
The lake sampling results are presented in full in Appendix D and
are summarized in the following table.

Discussion -
The control yields of the assay alga, Selenastrum capri-
cornutum, indicate that the potential primary productivity
of Hoover Reservoir was moderate to moderately high at the
time the sample was taken (04/26/73). Also, significant
increases in yields with the addition of phosphorus indicate
that the reservoir was limited by phosphorus at that time.
Note that the addition of nitrogen alone did not result in
yields significantly different than those of the controls.
The lake data substantiate phosphorus limitation; i.e.,
the mean inorganic nitrogen/orthophosphorus ratios were 50/1
or greater at all sampling stations and times.

IV. NUTRIENT LOADINGS
(See Appendix E for data)
For the determination of nutrient loadings, the Ohio National
Guard collected monthly near-surface grab samples from each of the
tributary sites indicated on the map (page v), except for the high
runoff months of February and March when two samples were collected.
Sampling was begun in May, 1973, and was completed in April, 1974.
Through an interagency agreement, stream flow estimates for the
year of sampling and a "normalized" or average year were provided by
the Ohio District Office of the U.S. Geological Survey for the
tributary sites nearest the lake.
In this report, nutrient loads for sampled tributaries were deter-
mined by using a modification of a U.S. Geological Survey computer
program for calculating stream loadings*. Nutrient loads shown are
those measured minus point-source loads, if any.
Nutrient loads for unsampled "minor tributaries and immediate
drainage" ("ZZ" of U.S.G.S.) were estimated using the means of the
nutrient exports, in kg/km2/year, at stations B-l and C-l and multi-
plying the means by the ZZ area in km2.
The community of Sunbury did not participate in the sampling pro-
gram, and nutrient loads were estimated at 1.134 kg P and 3.401 kg
N/capita/year. The nutrient loads in the untreated wastes of Galena
were estimated at 1.587 kg P and 4.263 kg N/capita/year.
* See Working Paper No. 175.
-------
Nutrient loads from the Walnut Bluffs, Lake Estates, and Bonanza
Mobile Home Park wastewater treatment plants were calculated using
the daily loads provided by the Ohio Environmental Protection Agency
(Youger, 1975); however, the nitrogen loads shown are based on total
Kjeldahl nitrogen only.

E. Yearly Loadings:
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 mesotrophic 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.
