FOREWORD
The National Eutrophication Survey was initiated in 1972 as a
research project in response to an Administration commitment to
investigate the nationwide threat of accelerated eutrophication to
fresh water lakes and reservoirs.
OBJECTI VES
The Survey was designed to develop, in conjunction with state
environmental agencies, information on nutrient sources, concentrations
and impact on selected fresh water 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, in fact, 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
This report documents the first stage of evaluation of lake and
watershed data collected from the study lake and its drainage basin.
It is formatted to provide state environmental agencies with specific
information for basin planning [ 3O3(e)], water quality criteria!
standards review [ 3O3(c)], clean lakes [ g314(a,b)], and water quality
monitoring [ lO6 and §305(b)] activities mandated by the Federal Water
Pollution Control Act Amendments of 1972.
-------
111
Beyond the single lake analysis, broader based correlations
between nutrient concentrations (and loading) and trophic
condition 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

I. CONCLUSIONS
A. Trophic Condition:
Low nutrient concentrations and chlorophyll a in conjunction
with summer depression of dissolved oxygen in the hypolimnion
signify a mesotrophic condition. This conclusion is confirmed
by State of Maine authorities.
B. Rate-Limiting Nutrient
Because of a significant loss of nutrients, the algal assay
results are not considered reliable. The lake data show that
the lake was nitrogen limited at the time the assay sample was
collected but phosphorus limited the other two sampling times.
C. Nutrient Sources; Controllability:
1. Point Sources - Provision of secondary wastewater treat-
ment at the communities of Patten and Island Falls would result
in sufficient phosphorus reduction to protect Mattawamkeag
Lake, as indicated by a comparison of Survey data with the
Vollenweider model.
2. Non-Point Sources - Areal contribution of primary
nutrients is relatively low for phosphorus (42.4% of total P),
while rather high for nitrogen (77.3% of total N).

II. INTRODUCTION
Mattawamkeag Lake is located on the West Branch of the Mattawamkeag
River in Aroostook County. Although much of the drainage is forested,
the area is noted for the production of potatoes, and at least one po-
tato processing plant is located in the immediate drainage area.
Mattawamkeag is a relatively shallow warmwater lake and provides an
excellent habitat for smallmouth bass, white perch, and chain pickerel.
Reportedly, some salmon are taken during early spring fishing. Except
for a few summer cottages, shoreline development is minimal.
Mattawamkeag Lake and Upper Mattawamkeag Lake are generally consid-
ered to be separate water bodies (see map, page v); however, the two are
broadly joined, and the levels and patterns of physical and chemical pa-
rameters are similar in both. Therefore, in this report the two parts
are treated as one water body.
Reportedly, the lake is consistently strongly humic colored with plati-
num scale values generally around 70 ppm. The color limits light pene-
tration to a degree and may account in part for the quite low chlorophyll
a measured during the Survey.

IV. LAKE WATER QUALITY SUMMARY
Mattawamkeag Lake 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 three
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 three stations for
phytoplankton identification and enumeration; and, during the last visit,
a single five-gallon depth-integrated sample was composited for algal
assay. Also each time, depth-integrated samples were collected at the
stations for chlorophyll a analyses. Maximum depths sampled were 14 feet
at station 1, 28 feet at station 2, and 6 feet at station 3.
It should be noted that the Survey Secchi disc values are con-
sistently less than those observed by the Maine Department of
Environmental Protection. Such variations could be attributed to
fluctuations in cloud cover or sun angle (ambient light conditions),
observer technique, water surface disturbance, or may, in fact, be
result of short-term water clarity differences.
Also in addition to greater Secchi disc values, personnel of the
Maine Department of Inland Fisheries and Game report their total
alkalinities and surface conductivities for Mattawamkeag Lake are
generally somewhat higher than the Survey values.

The results obtained are presented in full in Appendix B, 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

2. Discussion —
The control yield of the assay alga, Selenastrum capri-
cornutum , indicated a low potential primary productivity in
the sample at the time of assay. However, there was a loss
of about 8 pg/i of dissolved phosphorus and 60 pg/i of nitro-
gen from the time the sample was collected to the time the
assay was begun. Had these losses not occurred, the control
sample would probably have supported a moderate yield of
about 4 mg/i.
The assay sample appears to have been phosphorus limited;
however, had the nutrient losses noted above not occurred,
the sample probably would have shown nitrogen limitation (i.e.,
an N/P ratio of 11 or 12/1). Further, the N/P ratio in the
lake was 10/1 when the assay sample was collected.
-------
9
The lake appeared to have been limited by phosphorus
during the first two lake sampling periods as indicated
by nitrogen/phosphorus ratios of 21/1 and 20/1 at those
times.
D. Trophic Condition
Survey data denote a mesotrophic condition. In most
parameters measured, Mattawamkeag compares favorably with
Long Lake, Aroostook County, and Long Lake, Cumberland County;
i.e., nutrient and chlorophyll a concentrations were quite
low. Some depression of dissolved oxygen was noted at
station 2 in August 1972. Biologists with the State of Maine
Departments of Environmental Protection and Inland Fisheries
and Game support this conclusion.

V. NUTRIENT LOADINGS*
(See Appendix C for all data)
For the determination of nutrient loadings, from September, 1972,
through August, 1973, the Maine National Guard collected monthly near-
surface grab samples from each of the sites indicated on the map (page
v), except for the high runoff months of April and May, when two samples
were collected from most of the stations, and the colder months when one
or more samples were not collected at several stations because of low
flows or ice cover.
Stream flow estimates for the sampling year, and a “normalized” or
average year, were provided for the inlet (A-2), outlet (A-i) and direct
lake drainage (ZZ) by the Maine District Office of the U.S. Geological
Survey through an interagency agreement (See Appendix A). The flows for
Fish Stream (C-l), Upper Mattawamkeag River (A-3), Dyer Brook (B-i), and
Sly Brook, as well as sampling sites C-3 and C-2, were estimated by
determining the subdrainage areas in square miles by planimetry, ad-
justing the sum of these areas to equal the total drainage area calculated
by U.S.G.S.-, and then multipling these adjusted areas, in mi 2 , by the
runoff coefficient per mi 2 used by the U.S.G.S. for calculating A-2 flows
(see Appendix A for calculated flows).
In this report, tributary loadings were calculated using mean concen-
trations and mean flows. Nutrient loadings for unsampled Sly Brook and
* Based on sampling frequency and variations in concentrations, single
tributary loadings for gaged sites are believed to be within ±16% of
the true value 67% of the time and within ±32% of the true value 95%
of the time.
-------
11
“minor tributaries and immediate drainage” (“U” of U.S.G.S.) were cal-
culated using the mean nutrient concentrations of Fish Stream at site
C-3 and the estimated mean flows.
The untreated sewage discharges of Patten and Island Falls were not
sampled during the Survey. Nutrient loads for these communities were
derived by calculating the nutrient loads in the streams above and below
these sources, and the differences in the loads were attributed to the
point sources (e.g., the loads in Fish Stream at C-2 minus the Fish Stream
loads at C-3 = Patten loads).
Although the phosphorus load estimated for Patten in this way appears
reasonable compared to a per-capita estimate, the nitrogen load appears
to be about eight times higher than expected on a per-capita basis. Sur-
vey information and data do not provide an explanation for the high nitro-
gen load.
In the case of Island Falls, both phosphorus (2.6 x per-capita esti-
mate) and nitrogen loads (5.3 x per-capita estimate) are higher than ex-
pected. The differences are believed to be attributable to the potato
processing plant in Island Falls.

E. Yearly Loading Rates:
In the following table, the existing phosphorus loading
rates are compared to those proposed by Vollenweider (1973).
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”.
Total Phosphorus Total Nitrogen
Units Total Accumulated Total Accumulated
lbs/acr /yr 5.4 1.7 201.6 48.7
grams/rn /yr 0.60 0.19 22.6 5.5
Vollenweider loading rates for phosphorus (g/m 2 /yr) based on mean
depth and mean hydraulic retention time of Mattawamkeag Lake:
“Dangerous” (eutrophic rate) 1 .00
“Permissible” (oligotrophic rate) 0.50
F. Controllability of Nutrients:
1. Discussion —
During the sampling year, Mattawamkeag Lake received an
estimated total phosphorus load at a rate less than the
-------
16
“dangerous” (eutrophic) rate but more than the “permissible”
(oligotrophic) rate proposed by Vollenweider; i.e., a meso-
trophic rate. Of this load, it is estimated that Patten
contributed about 14%, and Island Falls contributed about
41%.
At this time, there are nine Maine comunities with
higher waste treatment plant construction priorities than
Patten and Island Falls, and Matthew Scott of the Maine
Department of Environmental Protection advises that the
two communities probably will not be funded for prepara-
tion of plans for secondary treatment before FY 1977. In
view of the existing mesotrophic loading rate, it seems
likely that the trophic condition of Mattawamkeag Lake
will not be changed appreciably in the intervening time.
In the following table, total phosphorus loadings that
can be achieved by specific levels of phosphorus removal
at the point sources of Patten and Island Falls (including
the 25% removal expected of secondary treatment plants)
are shown and compared to Vollenweider’s suggested load-
ing rates.

It will be noted that when the secondary waste treat-
ment facilities become operational, the loading rate to
Mattawamkeag Lake will be reduced to less than an oligo-
trophic rate. It appears, therefore, that additional
phosphorus removal at Patten and Island Falls will not
be necessary, although it is recognized that the propor-
tion of immediately-available orthophosphates will be
markedly increased with secondary treatment.
