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 [5303(e)]s water
quality criteria/standards review [§303(c)], clean lakes [§314(a,b)],
and water quality monitoring [5106 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

LAKE LORAMIE
STORE! NO. 3917
I. CONCLUSIONS
A. Trophic Condition:
Survey data indicate that Lake Loramie is eutrophic. It
ranked nineteenth in overall trophic quality when the 20 Ohio
lakes sampled in 1973 were compared using a combination of six
parameters*. Eighteen of the lakes had less median total phos-
phorus, 12 had less and one had the same median dissolved ortho-
phosphorus, 12 had less median inorganic nitrogen, 18 had less
mean chlorophyll £, and all of the other lakes had greater mean
Secchi disc transparency.
Survey limnologists did not observe any surface concentrations
of algae but noted that higher aquatic plants were abundant in
many areas of the lake.
Almost continuous dredging of the lake is required to main-
tain satisfactory depths (Ketelle and Uttormark, 1971).
B. Rate-Limiting Nutrient:
The algal assay results indicate Lake Loramie was phosphorus
limited at the time the sample was collected (05/04/73). The
lake data indicate phosphorus limitation in August as well but
nitrogen limitation in October.
* See Appendix A.

C. Nutrient Controllability:
1. Point sources—The phosphorus contribution of known
point sources amounted to 36% of the total load impacting Lake
Loramie during the sampling year. The Anna, Botkins, and
Minster wastewater treatment plants contributed 6.7%, 9.0%,
and 23.3% of the total phosphorus load to the lake, respec-
tively. It is estimated that septic tanks near the lake con-
tributed less than 1%.
The present phosphorus loading of 4.22 g/m2/yr is five
times that proposed by Vollenweider (Vollenweider and Dillon,
1974) as a eutrophic loading (see page 13). However, Vollen-
weider's model probably does not apply to water bodies with
short hydraulic retention times, and the mean hydraulic retention
time of Lake Loramie is only 29 days. In view of the question-
able applicability of the model and because the lake is mostly
phosphorus limited, all phosphorus inputs should be minimized
to the greatest practicable extent to slow the aging of Lake
Loramie.
2. Non-point sources—Nearly 64% of the total annual phos-
phorus input to Lake Loramie was contributed by non-point
sources. Loramie Creek contributed 41.4%, and the ungaged tribu-
taries were estimated to have contributed 21.9% of the total load.
The phosphorus export rate of Loramie Creek (49 kg/km2/yr) is
-------
3
somewhat high as compared to the two tributaries of nearby Indian
Lake* (20 and 34 kg/km2/yr). The higher rate may have resulted
from underestimation of the Anna and Botkins point-source loads,
or the electroplating firm at Anna may have contributed phos-
phorus directly to Clay Creek and thence to Loramie Creek (see
page 10).

III. LAKE WATER QUALITY SUMMARY
Lake Loramie 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 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 phyto-
plankton 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 depth
sampled at station 1 was 1.2 meters; only near-surface samples were
taken 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, Selenastrum cajjri-
cornutum, indicates that the potential primary productivity
of Lake Loramie was very high at the time the sample was
collected (05/04/73). The results also indicate the lake
was phosphorus limited. Note that the addition of phos-
phorus alone produced a significant increase in yield, but
the addition of only nitrogen produced a yield no greater
than that of the control.
The lake data indicate phosphorus limitation in August
as well (the mean inorganic nitrogen/orthophosphorus ratio
was 86/1). However, nitrogen limitation is indicated in
October (the mean N/P ratio was 4/1).
-------
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 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
/
determined by using a modification of a U.S. Geological Survey com-
puter 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 exports,
in kg/km2/year, at station D-l of nearby Indian Lake and multiplying
by the ZZ area in km2.
The communities of Anna, Botkins, and Minster did not participate
in the sampling program, and nutrient loads were estimated at 1.134 kg
P and 3.401 kg N/capita/year.

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.

* There was an apparent loss of nutrients during the sampling year. This
may have been due to solubilization of previously sedimented nutrients
during dredging (see page 1), recharge with nutrient-rich ground water,
unknown and unsampled point sources discharging directly to the lake, or
underestimation of the nutrient loads from the Minster sewage treatment
plant which discharges to an unsampled tributary.
