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.
-------
m
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 Michigan Department of
Natural Resources for professional involvement and to the
Michigan National Guard for conducting the tributary sampling
phase of the Survey.
A. Gene Gazlay, former Director, and David H. Jenkins, Acting
Director, Michigan Department of Natural Resources; and Carlos
Fetterolf, Chief Environmental Scientist, and Dennis Tierney,
Aquatic Biologist, Bureau of Water Management, Department of Natural
Resources, provided invaluable lake documentation and counsel during
the course of the Survey. John Vogt, Chief of the Bureau of Environ-
mental Health, Michigan Department of Public Health, and his staff
were most helpful in identfying point sources and soliciting municipal
participation in the Survey.
Major General Clarence A. Schnipke (Retired), then the Adjutant
General of Michigan, and Project Officer Colonel Albert W. Lesky,
who directed the volunteer efforts of the Michigan National Guardsmen,
are also gratefully acknowledged for their assistance to the Survey.

STORE! NO. 2618 .
I. CONCLUSIONS
A. Trophic Condition:
Survey data and the records of others (Ketelle and Uttormark,
1971) show that Lake Chemung is eutrophic. Of the 35 Michigan
lakes sampled in November when essentially all were well-mixed,
17 had less mean total phosphorus, nine had less mean dissolved
phosphorus, but only one had less mean inorganic nitrogen; of the
41 Michigan lakes sampled, 23 had less mean chlorophyll a_, but
only five had greater Secchi disc transparency*. Depletion or
near-depletion of dissolved oxygen occurred at and below 25 feet
at both sampling stations in June and in September.
Reportedly (Ketelle and Uttormark, op. cit.), rooted aquatic
vegetation grows profusely in the shallower areas of the lake.
B. Rate-Limiting Nutrient:
The algal assay results and the lake data show that Lake
Chemung was phosphorus limited in September, 1972. However,
the lake data indicate nitrogen limitation in June and November.
C. Nutrient Controllability:
1. Point sources—During the sampling year, Lake Chemung
received a total phosphorus load at a rate less than that
See Appendix A.
-------
proposed by Vollenweider (in press) as "dangerous" but greater
than his suggested "permissible" rate; i.e., a mesotrophic rate
(see page 12).
Other than septic tanks, there are no known point sources
impacting Lake Chemung. However, the favorable mesotrophic
phosphorus loading rate may be due to underestimation of septic
tank loads. A shoreline survey would be needed to determine the
actual contri butions.
2. Non-point sources—It is estimated that non-point sources,
including precipitation, contributed about 48% of the total phos-
phorus load to Lake Chemung during the sampling year.
The phosphorus export of the Unnamed Creek (B-l) does appear
to be excessive and is comparable to the exports of other unim-
pacted Michigan streams sampled during the Survey year (see page
12).

III. LAKE WATER QUALITY SUMMARY
Lake Chemung was sampled three times during the open-water season
of 1972 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 a number of depths at each station (see
map, page v). During each visit, a single depth-integrated (15 feet
to surface) sample was composited from the stations for phytoplankton
identification and enumeration; and during the second visit, a single
five-gallon 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_ analyses. The maximum depths sampled
were 35 feet at station 1 and 65 feet at station 2.
The results obtained are presented in full in Appendix C, and the
data for the fall sampling period, when the lake was essentially well-
mixed, are summarized below. Note, however, the Secchi disc summary
is based on all values.
For differences in the various parameters at the other sampling
times, refer to Appendix C.

The control yield of the assay alga, Selenastrum capri-
cornutum, indi
cates that the potential primary
productivity
of Lake Chemung was moderately high at the time the sample
was collected (09/19/72). Also, increasing yields with in-
creasing increments of orthophosphorus, up to about 0.020
mg/1, indicate that the lake was phosphorus limited. At
-------
8
orthophosphorus concentrations higher than about 0.020
mg/1, yields do not change significantly until nitrogen
is also added. This indicates the lake probably would
become nitrogen limited if orthophosphorus concentrations
exceeded 0.020 mg/1 (assuming nitrogen concentrations did
not change). Note that the addition of only nitrogen
resulted in a yield not significantly different from the
control yield.
The lake data also indicate phosphorus limitation in
September (N/P ratio = 15/1). However, nitrogen limitation
is indicated for June and November (N/P ratios were less
than 10/1, and nitrogen limitation would be expected).
-------
IV. NUTRIENT LOADINGS
(See Appendix D for data)
For the determination of nutrient loadings, the Michigan 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 April and May, when two samples were collected, and
December when low flows prevented sampling. Sampling was begun in
October, 1972, and was completed in October, 1973.
Through an interagency agreement, stream flow estimates for the
year of sampling and a "normalized" or average year were provided by
the Michigan 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 loadings for unsam-
pled "minor tributaries and immediate drainage" ("II" of U.S.G.S) were
2
estimated by using the nutrient loads, in Ibs/mi /year, in the unnamed
2
creek at station B-l and multiplying by the II area in mi .
There are no known municipal or industrial point sources impacting
Lake Chemung.

E. Yearly Loading Rates:
In the following table, the existing phosphorus loading
rates are compared to those proposed by Vollenweider (in press).
Essentially, his "dangerous" rate is the rate at which the
receiving waters would become eutrophic or remain eutrophic;
q
his "permissible" rate is that which would result in the
receiving water remaining oligotrophic or becoming oligo-
trophic if morphometry permitted. A mesotrophic rate would
be considered one between "dangerous" and "permissible".
