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)
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.

MONA LAKE
STORET NO. 2691
I. CONCLUSIONS
A. Trophic Condition:
Survey data show that Mona Lake is eutrophic. Of the 35
Michigan lakes sampled in November when essentially all were
well-mixed, only one had greater mean total and dissolved
phosphorus, and 13 had greater mean inorganic nitrogen; of
the 41 Michigan lakes sampled, only six had more mean chloro-
phyll a^, but 17 had less Secchi disc transparency*.
Dissolved oxygen was depleted at 31 feet at station 2 in
September and was depressed at about 20 feet at station 1 in
June and September.
Ketelle and Uttormark (1971) report that Mona Lake has a
long history of algal blooms.
B. Rate-Limiting Nutrient:
The results of the algal assay show that Mona Lake was nitro-
gen limited in September, 1972. The lake data indicate nitrogen
limitation at the other sampling times as well.
C. Nutrient Controllability:
1. Point sources—During the sampling year, Mona Lake
received a total phosphorus load at a rate about eight times
* See Appendix A.
-------
the rate proposed by Vollenweider as "dangerous"; i.e., a eu-
trophic rate (see page 13). Now, Vollenweider's model may not
be applicable to water bodies with short hydraulic retention
times, and the mean.hydraulic retention time of Mona Lake is
76 days.
The sewage effluent of the only known point source impact-
ing Mona Lake (the City of Muskegon Heights) was diverted to
a cropland spray-irrigation system in May of 1973 (Bastian,
1974). However, prior to diversion, it is estimated that this
source contributed about 84% of the total phosphorus load reach-
ing Mona Lake during the sampling year.
After diversion of the point source phosphorus load, it is
2
calculated that the loading rate was reduced to 0.88 g/m /yr;
and, while this rate is still in excess of the eutrophic rate
2
of 0.68 g/m /yr, in view of the questionable applicability of
Vollenweider's model, it is believed the trophic condition of
Mona Lake will improve significantly once a new phosphorus
equilibrium becomes established.
2. Non-point sources—During the sampling year, it is
estimated that non-point sources, including precipitation,
contributed only about 16% of the total phosphorus load to
Mona Lake.
The phosphorus export of Black Creek does not appear to
have been excessive (see page 13) and is comparable to the
-------
exports of other Michigan streams sampled; e.g., Green Creek
and the Muskegon River tributary to nearby Muskegon Lake
(Working Paper No. 203).

III. LAKE WATER QUALITY SUMMARY
Mona Lake was sampled three times during the open-water season of
>,y
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 or near bottom to
surface) sample was composited from the stations for phytoplankton identi-
fication 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 20 feet at sta-
tion 1 and 31 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.

alga, Selenastrum capri-
cornutum, indicates that the potential primary
productivity
of Mona Lake was very high at the time the assay sample was
collected (09/19/72). Also, the lack of significant change
in yields with increased levels of orthophbsphorus, until
nitrogen was also added, indicates that Mona Lake was nitro-
gen limited at the time the assay sample was collected. Note
-------
8
that the addition of only nitrogen resulted in a yield far
greater than the control.
Nitrogen limitation is also indicated by the lake data;
i.e., the nitrogen to phosphorus ratios were less than 4 to
1 at all sampling times.
-------
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 tribu-
tary sites indicated on the map (page v), except for the high runoff
months, when two samples were collected, and the colder months when sam-
ples were not taken at B-l because of low flows. Sampling was begun in
October, 1972, and was completed in September, 1973.
Through an interagency agreement, stream flow estimates for the year
of sampling and a "normalized" or average year were provided by the Michi-
gan District Office of the U.S. Geological Survey for the tributary sites
nearest the lake.
In this report, nutrient loads for the lake outlet and Black Creek
were determined by using a modification of a U.S. Geological Survey com-
puter program for calculating stream loadings*. However, the nutrient
loads calculated for Little Black Creek were less than the estimated
Muskegon Heights loads to the creek, so the non-point nutrient loads
for Little Black Creek and the unsampled "minor tributaries and immediate
drainage" ("ZZ" of U.S.G.S.) were estimated by using the nutrient loads,
2
in Ibs/mi /yr, in Black Creek at station A-2 and multiplying by the Little
2
Black Creek and ZZ areas in mi .
See Working Paper No. 1.
-------

The operation of Muskegon Heights wastewater treatment plant was
discontinued in May of 1973, when the Muskegon County land-disposal
system became operative. Therefore, the nutrient loads attributed
to the Muskegon Heights STP were estimated at 2.5 Ibs P and 7.5 Ibs
N/capita/yr and were adjusted for the eight months of operation that
occurred during the sampling year (it is noted that nutrient concen-
trations in Little Black Creek below the STP had not diminished appre-
ciably through September, 1973).

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;
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".
Note that Vollenweider's model may not be applicable to
water bodies with very short hydraulic retention times.
