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
reservoi rs.
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.

LAKE MACATAWA
STORE! NO. 2648
I. CONCLUSIONS
A. Trophic Condition:
Survey data show that Lake Macatawa is eutrophic. Of the
35 Michigan lakes studied, 32 had better overall water quality
based on the parameters measured during the Survey, and only
two had lower overall quality; none of the 35 had less Secchi
disc transparency, only 3 had greater mean inorganic nitrogen,
and 7 had more mean total phosphorus*. Survey limnologists
noted a heavy algal bloom in September, 1972.
Ketelle and Uttormark (1971) report that this lake has
severe and frequent algal blooms.
B. Rate-Limiting Nutrient:
There was a significant loss of phosphorus in the algal assay
sample, and the results are not representative of conditions in
the lake at the time the sample was collected. The lake data
indicate phosphorus limitation at all sampling times.
C. Nutrient Controllability:
1. Point sources—During the sampling year, Lake Macatawa
received a total phosphorus load at a rate nearly eight times
that proposed by Vollenweider (in press) as "dangerous"; i.e.,
* See Appendix A.
-------
a eutrophic rate (see page 13). It is calculated that the
cities of Holland and Zeeland contributed almost 55% of this
load.
Primarily for the protection of Lake Michigan, the cities
of Holland and Zeeland are required to provide 80% phosphorus
removal, but it appears this may not have been completely
implemented during the sampling year judging by the phosphorus
loads measured (1.2 Ibs/capita/year at the Holland STP and 4.8
Ibs/capita/year at the Zeeland STP). However, it is calculated
that even 100% removal at the STP's would still leave a loading
2
rate of 25.5 Ibs/acre/yr (2.86 g/m /yr) or over three times the
2
eutrophic rate of 0.80 g/m /yr. While a high degree of phosphorus
removal at the municipal point sources could be expected to at
least reduce the incidence and severity of nuisance algal"blooms,
it appears that a marked improvement in the trophic condition of
the lake will require control of phosphorus from other sources
as well (see below).
2. Non-point sources (see page 12)--During the sampling
year, the phosphorus export rate of the Black River was a very
high 300 Ibs per square mile of drainage as compared to a
2
"regional" mean export rate of 59 Ibs/mi /yr measured in
-------
unimpacted tributaries to Mona Lake, Muskegon Lake, and Lake
Allegan*.
Although the Survey did not involve industries, in a
Michigan Department of Natural Resources report, Jackson
(1971) noted that there are ten industrial discharges to the
Black River and the lake, as well as seven storm drains.
Several of these discharges are believed to be significant
nutrient sources and probably account for the very high
Black River phosphorus export noted above.
If the phosphorus export rate of the Black .River can be
reduced to the regional mean and at least 80% phosphorus
removal is attained at the municipal sources, it is calcu-
lated that the phosphorus loading rate could be reduced
2
from the 6.35 g/m measured during the sampling year to
2
about 2.2 g/m /yr. Considering the relatively short mean
hydraulic retention time of the lake (77 days), it is likely
that the reduced phosphorus loading would result in a signifi-
cant improvement in the trophic condition of Lake Macatawa
and provide additional protection for Lake Michigan as well.
* Black Creek (65 Ibs P/mi /yr) to Mona Lake; Muskegon River (59 Ibs)
and Green Creek (55 Ibs) to Muskegon Lake; and Dumont Creek (57 Ibs)
to Lake Allegan.

III. LAKE WATER QUALITY SUMMARY
Lake Macatawa 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 (a third station was sampled once) 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^ anal-
yses. The maximum depths sampled were 21 feet at station 1, 20 feet at
station 2, and 21 feet at station 3.
The results obtained are presented in full in Appendix C, and the
data for the fall sampling period, when the lake essentially was well-
mixed, are summarized below. Note, however, the Secchi disc summary
is based on all values.

C. Limiting Nutrient Study:
There was a loss of about 41% of the total phosphorus
in the algal assay sample from the time of collection until
the assay was begun. Consequently, the results are not
representative of conditions in the lake at the time the
sample was taken.
The lake data indicate phosphorus limitation at all samp-
ling times (the N/P ratios were 22/1 in June, 14/1 in Septem-
ber, and 20/1 in November; and phosphorus 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
the colder months when one or more samples were omitted 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 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" ("ZZ" of U.S.G.S.) were
2
estimated by using the nutrient loads, in Ibs/mi /year, in Pine Creek
2
at station B-l and multiplying by the ZZ area in mi .
The apparent high degree"of retention of phosphorus (73%) and
nitrogen (42%) in Lake Macatawa during the sampling year is attributed
to periodic dilution of the outlet samples by better quality Lake
* See Working Paper No. 1.

Michigan waters when on-shore winds occur. This dilution has been
noted before (Jackson, 1971) and continues to be a problem in ob-
taining representative outlet samples (Massey, 1975).
The operators of the Holland and Zeeland wastewater treatment plants
provided monthly effluent samples and corresponding flow data.
In the following loading tables, the nutrient loads attributed to
the Black River are those measured at station A-2 minus the Zeeland
loads.

2. Industrial - Jackson (op. cit.) listed 12 industries and
seven storm drains in the Lake Macatawa drainage; at
least two of the industries involved food processing
and were possible sources of nutrients. However, because
of Survey constraints** these sources were not evaluated.

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.
Total Phosphorus Total Nitrogen
Units _ Total Accumulated* Total Accumulated*
Ibs/acre/yr 56.6 41.2 567.0 240.0
grams/m2/yr 6.35 4.61 63.6 26.9
Vollenweider loading rates for phosphorus
(g/m^/yr) based on mean depth and mean
hydraulic retention time of Lake Macatawa:
"Dangerous" (eutrophic rate) 0.80
"Permissible" (oligotrophic rate) 0.40
* The apparent high degree of accumulation (retention) of phosphorus
(73%) and nitrogen (42%) during the sampling year is attributed to
periodic dilution of outlet samples by Lake Michigan waters (see
pages 9 and 10).
