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)], water
quality criteria/standards review [§303{c)L 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,

I. CONCLUSIONS
A. Trophic Condition:
Survey data indicate that Rocky Fork Reservoir is eutro-
phic. The reservoir ranked eighth when the 20 Ohio lakes
sampled in 1973 were compared using a combination of six lake
parameters*. Six of the lakes had less median total phos-
phorus, six had less median dissolved phosphorus, ten had less
median inorganic nitrogen, ten had less mean ch.lorophyll a_,
and eight had greater mean Secchi disc transparency. Dissolved
oxygen was markedly depressed or depleted in all samples taken
at 4.6 meters or deeper in August and October, 1973.
Survey limnologists noted concentrations of algae at all
stations in April.
B. Rate-Limiting Nutrient:
The algal assay results indicate phosphorus limitation at
the time the sample was taken (04/28/73). The lake data indi-
cate phosphorus limitation at the other sampling times as well.
C. Nutrient Controllability:
1. Point sources—The phosphorus load from the Hillsboro
wastewater treatment plant amounted to 30.8% of the total reach-
ing the reservoir during the sampling year. Six smaller point
sources collectively contributed less than 1% of the total load.
The present loading of 2.05 g/m2/yr is almost three times

that proposed by Vollenweider (Vollenweider and Dillon, 1974)
as a eutrophic loading (see page 12). A reduction of 10,930
kg/yr in the total load is needed to reach the eutrophic load-
ing of 0.7 g/m2/yr. Although a reduction of that magnitude
is not possible at the Hillsboro treatment plant and the six
small point sources, the reservoir is phosphorus limited, and
a high degree of point-source phosphorus control should improve
the water quality of the reservoir.
2, Non-point sources—The phosphorus contribution of non-
point sources amounted to 68.4% of the total load. Of the
gaged tributaries, Clear Creek contributed 42.9%; Rocky Fork,
7.4%; and Blinco Branch, 3.2%. The ungaged drainage area was
estimated to have contributed 14.0% of the total.
The non-point phosphorus export rate of the Clear Creek
drainage area was considerably higher than the rates of the
other gaged tributaries Csee page 12). This may have resulted
from an underestimation of the phosphorus load from the Hills-
boro treatment plant or other point sources discharging to
this creek. In any case, a reduction of the phosphorus export
of Clear Creek would reduce the total phosphorus loading to
Rocky Fork Reservoir.

III. LAKE WATER QUALITY SUMMARY
Rocky Fork 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 three 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 12.2 meters at station 1, 6.7 meters at station 2,
and 1.5 meters at station 3.
The lake sampling results are presented in full in Appendix D and
are summarized in the following table.

2. Discussion -
The control yield of the assay alga, Selenastrum ca pr i-
cornutum, indicates that the potential primary productivity
of Rocky Fork Lake was moderately high at the time the
sample was collected (04/28/73). A significant increase in
yield occurred when phosphorus was added alone and in
combination with nitrogen. The increase in yield when only
nitrogen was added is not considered significant as compared
to that of the control.
The lake data indicate phosphorus limitation at all
sampling times (the mean inorganic nitrogen/orthophoshorus
ratios were 66/1 or greater, and phosphorus limitation
would be expected).

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 month of March when three 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 loads, in kg/km2/year, at stations B-l and C-l and multiply-
ing the means by the ZZ area in km2.
The operator of the Hillsboro wastewater treatment plant provided
monthly effluent samples and corresponding flow data. The operators
of the treatment plants serving Rocky Fork State Park, Pleasant Acres
Mobile Home Park, and Rocky Fork Marine Sales and Service did not

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 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.
