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 [5303(c)j, 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.
-------
ill
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.

I. CONCLUSIONS
A. Trophic Condition:
Survey data indicate that Pleasant Hill Reservoir is eutro-
phic. It ranked third in overall trophic quality when the 20
Ohio lakes sampled in 1973 were compared using a combination
of six parameters*. One of the lakes had less median total
phosphorus, six had less and one had the same median dissolved
phosphorus, six had less median inorganic nitrogen, seven had
less mean chlorophyll a^ but none of the lakes had greater mean
Secchi disc transparency. Marked depression of dissolved oxygen
with depth occurred at station 2 in July and October.
Survey limnologists noted much rooted aquatic vegetation along
the shoreline between stations 1 and 2 (see map, page v).
B. Rate-Limiting Nutrient:
The algal assay results indicate that the primary productivity
of Pleasant Hill Reservoir was limited by phosphorus at the time
the sample was taken (04/20/73). The lake data indicate phosphorus
limitation at all sampling stations and times.
* See Appendix A.
-------

C. Nutrient Control]ability:
1. Point sources--The phosphorus contribution of known
point sources accounted for 71.1% of the total load reaching
Pleasant Hill Reservoir during the sampling year. The waste-
water treatment plant at Lexington contributed 39.2%, the plant
at Belleville contributed 22.0%, and the'plant at Butler con-
tributed 9.9% of the total. In addition, four industrial
sources discharge to the reservoir via Switzer Creek and an
unnamed tributary of the Mohican River (see page 10). However,
phosphorus loads from these sources probably are relatively
insignificant as indicated by the low phosphorus export rates
of the tributaries (see discussion of non-point sources below).
The present phosphorus loading of 3.51 g/m2/yr is 2.5 times
that proposed by Vollenweider (Vollenweider and Dillon, 1974)
as a eutrophic loading (see page 13). A 90% reduction in the
phosphorus inputs of the listed point sources would lower the
loading to 1.26 g/m2/yr which is less than a eutrophic loading.
The reduction should result in improvement in the trophic condition
since the reservoir is phosphorus limited, and the mean hydraulic
retention time is a relatively short 35 days.
-------
2. Non-point sources—The phosphorus contribution of
non-point sources accounted for 28.9% of the total phosphorus
input to the reservoir. The Mohican River contributed 14.2%,
Switzer Creek contributed 3.7%, and the remaining three tribu-
taries contributed 6.4% of the total, collectively. Ungaged
tributaries were estimated to have contributed 4.1% of the total
The phosphorus exports of the sampled tributaries were
relatively low as compared to Ohio streams sampled elsewhere
(see page 13). For example, the mean of the phosphorus export
rates of the Pleasant Hill Reservoir tributaries was 11 kg/km2/
yr (range of 5-16 kg/km2/yr) while Delaware Reservoir* tribu-
taries had a mean export rate of 73 kg/km2/yr (range of 37-129
kg/km2/yr), and Grand Lake of St. Marys** tributaries had a
mean rate of 70 kg/km2/yr (range of 45-131 kg/km2/yr).
The low export rates indicate that phosphorus loads from the
industrial point sources probably are negligible.

III. LAKE WATER QUALITY SUMMARY
Pleasant Hill 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 two stations on the lake and from two or more depths at each sta-
tion (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 2.4 meters at station 1 and 11.0 meters at station 2.
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, S e1 en a s trurn cap r i-
c_Qr_nu_t_um, indicates that the potential primary productivity
of Pleasant Hill Reservoir was moderately low at the time
the sample was collected (04/20/73). Also, the significant
increase in yield when only phosphorus was added indicates
that this body of water was limited by phosphorus at that
time. Note that the addition of only nitrogen resulted in
a yield not significantly greater than that of the control.
The lake data substantiate phosphorus limitation; i.e.,
the mean inorganic nitrogen/orthophosphorus ratios were 18/1
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 loads, in kg/km2/year, at stations C-l and E-l and multiply-
ing the means by the ZZ area in km2.
The operators of the Belleville and Lexington wastewater treatment
plants provided monthly effluent samples and corresponding flow data.
The community of Butler did not participate in the Survey, and nutrient
loads were estimated at 1.134 kg P and 3.401 kg N/capita/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.
