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.

GRAND LAKE OF ST. MARYS
STORET NO. 3927
I. CONCLUSIONS
A. Trophic Condition:
Survey data indicate that Grand Lake of St. Marys is
eutrophic. It ranked seventh in overall trophic quality
when the 20 Ohio lakes sampled in 1973 were compared using
a combination of six parameters*. Fifteen of the lakes
had less median total phosphorus, ten had less median
dissolved phosphorus, one had less median inorganic nitro-
gen, 17 had less mean chlorophyll a_, and 14 had greater
mean Secchi disc transparency.
Survey limnologists reported heavy algal blooms at
stations 2, 3, and 4 in May.
Almost continuous dredging of the lake is required
to maintain satisfactory depths (Ketelle and Uttormark,
1971).
B. Rate-Limiting Nutrient:
The algal assay sample was lost in shipment. However,
the lake data indicate phosphorus limitation at all sam-
pling stations in May and at three of the four stations
in August. The October data indicate nitrogen limitation
at all stations.
C. Nutrient Controllability:
]'. Point sources - During the sampling year, the
phosphorus contribution of the listed point sources
* See Appendix A
-------
amounted to only 8.0% of the input to Grand Lake of
St. Marys, The wastewater treatment plant at St. Henry
and septic tanks serving lakeshore dwellings were esti-
mated to have accounted for 6.7% and 1.3% of the total,
respectively.
The present phosphorus loading of 0.49 g/m2/yr is
1.8 times greater than that proposed by Vollenweider (Vol-
lenweider and Dillon, 1974) as a eutrophic loading (see page
14). While even complete removal of phosphorus at the
St. Henry treatment plant would not reduce the loading
to the eutrophic level, the lake Is phosphorus limited
much of the time, and point-source phosphorus control
should result in at least some improvement in the trophic
condition of the lake, particularly if a significant por-
tion of the phosphorus exports of two of the tributaries
proves to be controllable (see below).
2. Non-point sources - It is estimated that phos-
phorus contribution of non-point sources accounted for 92%
of the total load impacting Grand Lake of St. Marys during
the sampling year. However the phosphorus export rates
of several of the tributaries were high (see page 13) as
compared to the 49 kg/kmz/yr rate of Loramie Creek, a
tributary of nearby Lake Loramie*. At least part of
the higher export rates probably is due to agricultural
runoff which is reported to be a problem in the lake
Working Paper No. 405.
-------
drainage basin (Youger, 1975). However, the 127 kg/km2/yr
rate of Coldwater Creek may have resulted from an unsampled
point source (the Avco New Idea Company; see page 10), under-
estimation of the St. Henry wastewater treatment plant load,
or both.
The high export rate of Prairie Creek (131 kg/km2/yr)
may have been due to discharges from the community of
Sebastian. The National Guard tributary samplers reported
that at times the waters of this creek were black and had
an odor of raw sewage (Herfurth, 1973).

III. LAKE WATER QUALITY SUMMARY
Grand Lake of St. Marys 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 one or more depths at each
station (see map, page v). During each visit, a single depth-integrated
(near bottom to surface) sample was composited from the stations for
phytoplankton identification and enumeration; and a similar sample was
collected from each of the stations for chlorophyll ^analysis. A
sa-nple was also collected for algal assays but was lost in shipment.
The maximum depths sampled were 1.2 meters at station 1, 0.9 meters at
station 2, 1.5 meters at station 3, and 0.9 meters at station 4.
The lake sampling results are presented in full in Appendix D and
are summarized in the following table.

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 March and April 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" ("II" of U.S.G.S.) were estimated using the means of the
nutrient loads, in kg/km2/year, at stations B-l and F-l and multiply-
ing the means by the II area in km2.
The community of St. Henry 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.
