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)], 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.
-------
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)

I. CONCLUSIONS
A. Trophic Condition:
Survey data indicate that Delaware Reservoir is eutrophic
It ranked 12th in overall trophic quality when the 20 Ohio lakes
sampled in 1973 were compared using a combination of six param-
eters*. Eight lakes had less median total phosphorus, 15 had
less median dissolved phosphorus, 16 had less median inorganic
nitrogen, 13 had greater mean Secchi disc transparency, but only
two had less mean chlorophyll a^. Marked depression of dissolved
oxygen with depth occurred at station 1 in August and October.
B. Rate-Limiting Nutrient:
The algal assay results indicate that the 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 we!1.
C. Nutrient controllability:
1. Point sources—During the sampling year, the phosphorus
contribution from point sources, other than septic tanks, amounted
to 21.1% of the total load to Delaware Reservoir. The Galion
wastewater treatment plant was the most significant point source
and accounted for 15.6% of the total phosphorus load. The remaining
* See Appendix A.
-------
2
point sources contributed just over 5%.
The present phosphorus loading of 12.49 g/m2/yr is over
nine times that proposed by Vollenweider (Vollenweider and
Dillon, 1974) as a eutrophic loading (see page 12). However,
the mean hydraulic retention time of Delaware Reservoir is a
rather short 23 days (at normal pool level), and Vollenweider's
model may not apply.
While even complete removal of phosphorus at the known point
sources would only reduce the loading to 9.85 g/m2/yr, in view of
the questionable applicability of Vollenweider's model, it is
likely that a high degree of phosphorus removal would at least
reduce the incidence and severity of nuisance algal blooms in
the reservoir if other sources of phosphorus also can be controlled
(see below).
2. Non-point sources—During the sampling year, the phosphorus
export rates of Grave and QuQua creeks were markedly higher than
the export rates of the other streams in the reservoir drainage
(see page 12). Because of the proximity of these two streams to
the City of Marion, it is likely urban drainage caused the higher
export rates.
In all, non-point sources, excluding precipitation, are esti-
mated to have contributed 78.6% of the total phosphorus load to the
reservoir during the sampling year.

III. LAKE WATER QUALITY SUMMARY
Delaware 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 one or more 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 8.2 meters at station 1 and 2.1 meters at station 2;
only near-surface samples were taken at station 3.
The 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 capri-
cornutum, indicates that the potential primary productivity
of Delaware Reservoir was moderate at the time the sample
was collected (04/26/73). The yield increased substantially
with the addition of phosphorus alone but not with the addition
of nitrogen alone. This indicates phosphorus was the limiting
nutrient.
The lake data indicate phosphorus limitation at all sampling
times; the mean ratios of inorganic nitrogen/orthophosphorus
were 77/1, 88/1, and 50/1 in April, August, and October, respec-
tively, 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 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 nutrient loads,
in kg/km2/year, at station B-l and multiplying by the ZZ area in km2.
The operators of the Gal ion and Mt. Gilead wastewater treatment
plants provided monthly effluent samples and corresponding flow data
The operator of the Delaware State Park plant did not participate in
the Survey, and nutrient loads were estimated at 1.134 kg P and 3.401
N/capita/year.
* See Working Paper No. 175.
-------
Nutrient loadings for the Village of Cardington were estimated at
1.587 kg P and 4.263 kg N/capita/year for 30% of the population during
the months of May through September and 1.134 kg P and 3.401 kg N/capita/
year for the total population during the months of October through April
(from May through September, 1973, approximately 3Q% of the population
served discharged untreated sewage to Whetstone Creek; Gompf, 1975).

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 the
rate 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.
