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.
OBJECTIVES
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. W th 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)J, clean lakes [ 3l4(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
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 of 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.
ACKNOWL EDGMENT
The staff of the National Eutrophication Survey (Office of
Research & Development, U. S. Environmental Protection Agency)
expresses sincere appreciation to the Maine Department of
Environmental Protection for professional involvement and to the
Maine National Guard for conduct of the tributary sampling phase
of the Survey.
William R. Adams, Commissioner of the Department of Environmental
Protection, and William P. Hinckley and Matthew Scott of the Division
of Lakes and Biological Studies, provided invaluable lake documentation
and counsel during the course of the study.
Major General Edwin W. Heywood (Retired), then the Adjutant
General of Maine, and Project Officer Lieutenant Colonel Earl B. Adams
who directed the volunteer efforts of the forty-one participating Maine
National Guardsmen are also gratefully acknowledged for their assistance
to the Survey.

I. CONCLUSIONS
A. Trophic Condition:
Survey data indicate that Rangeley Lake is oligotrophic.
Agency personnel of the State of Maine also consider the lake
to be oligotrophic on the basis of their more extensive data.
B. Rate-Limiting Nutrient:
Algal assay results and lake data show that Rangeley Lake
was phosphorus limited when sampled.
C. Nutrient controllability:
During the sampling year, about 78% of the total phosphorus
load to Rangeley Lake was contributed by non-point or areal
sources, while the community of Rangeley was contributing about
15%, and camp and home septic tanks around the lake were esti-
mated to have contributed about 7%.
Construction of 95% phosphorus removal facilities at Rangeley
is scheduled in 1974. This degree of treatment should help pre-
serve the present excellent quality of Rangeley Lake.
At present, septic tank contributions may not be a problem.
However, as lakeshore development progresses to meet increasing
recreational needs, consideration should be given to the control
of these sources to further protect the lake.

II. INTRODUCTION
Rangeley Lake has been famous for its cold-water game fishery since
the middle of the nineteenth century. Fishing pressure on the lake is
presently heavy and increasing, with salmon and trout predominant in the
catch.
In addition to fishing, the lake is highly valued for swimming, boat-
ing, scenic enjoyment, and storage of water for hydroelectric power gen-
eration (the Union Water Power Company, Lisbon, controls about 11% of
the volume by means of a small dam at the outlet). The watershed is mostly
forested; and until the early 1950’s, the lake was utilized periodically
for log-driving operations.
The region is now undergoing rapid development for outdoor recrea-
tional purposes with steady growth in both permanent (presently about
1,500) and seasonal population (presently peaking at about 13,000).
Much of the shoreline of the lake is developed with camps and homes.
Most of these are served by septic tanks, although reportedly the
soil does not provide adequate absorption of tank effluents. While the
lake receives no industrial discharges, it does receive secondary efflu-
ent from the Rangeley wastewater treatment plant via Haley Pond, and a
nutrient load of unknown magnitude is contributed directly by Rangeley
storm sewers.
The Rangeley plant became operational in the fall of 1970; and report-
edly algal blooms in Haley Pond have occurred since then. At times, large
plumes of algae reach City Cove of Rangeley Lake via the pond outlet and
reduce the aesthetic quality of that portion of the lake.

IV. LAKE WATER QUALITY SUMMARY
Rangeley 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 assays. Also each
time, a depth-integrated sample was collected from each of the stations for
chlorophyll a analysis. Maximum depths sampled were 14 feet at station 1,
64 feet at station 2, and 20 feet at station 3.
It should be noted that the Survey Secchi disc values are consistently
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 dis-
turbance, or may, in fact, be the result of short-term water clarity dif-
ferences.
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
values.
For differences in the various parameters at the other sampling times,

scussion -
The control yield of the assay alga, Selenastrum ç pri-
cornutum , indicates that the potential primary productivity
of Rangeley Lake was relatively low at the time the sample
was collected. Also, the increased yield resulting from the
first orthophosphorus spike shows that Rangeley Lake was phos-
phorus limited. At ortho-P concentrations higher than about
0.018 mg/i, however, yields do not change significantly until

nitrogen is also added which indicates the lake would become
nitrogen limited if ortho-P concentrations in the lake were
increased to about 0.018 mg/i. Note that the addition of only
nitrogen produced a yield not significantly different than the
control yield.
Lake data indicate that Rangeley Lake was phosphorus lim-
ited at the other sampling times as well. Nitrogen to phos-
phorus ratios were 69 to 1 and 20 to 1 in June and August,
respectively (phosphorus limitation would be expected with N/P
ratios of 14 to 1 or greater).
D. Trophic Condition:
Survey data indicate that Rangeley Lake is oligotrophic, and
personnel of the Maine Department of Environmental Protection
classify the lake as oligotrophic on the basis of their more ex-
tensive sampling. Nutrient concentrations were very low, and
Secchi disc transparencies were exceptional.
Generally, chlorophyll a levels were quite low. However, at
station 1 in City Cove, which receives the Haley Pond overflow,
two of the three samples had chlorophyll levels higher than
would be expected. It is believed these higher chlorophyll levels
resulted from the overflows of Haley Pond. Reportedly, green plumes
of algae-laden water from Haley Pond occur frequently in City Cove.
In all other parameters measured, Rangeley Lake is quite com-
parable to oligotrophic Moosehead and Sebago lakes.

V. NUTRIENT LOADINGS*
(See Appendix B for data)
For the determination of nutrient loadings, from September, 1972,
through August, 1973, the Maine National Guard collected monthly near-
surface grab samples from the tributary sites indicated on the map
(page v), except for the high runoff months of April and May, when two
samples per month were collected. Stream flow estimates were provided
by the Maine District Office of the U.S. Geological Survey through an
interagency agreement.
Discharges from the Rangeley wastewater treatment plant were sampled
by the operator on a monthly basis and flow data were provided. The phos-
phorus load reported for the plant was adjusted for partial retention in
Haley Pond into which the effluent is discharged (see discussion, pages
12 and 13).
In this report, tributary nutrient loads were calculated with mean
concentrations and mean flows. The loads for unsampled “minor tribu-
taries and immediate drainage” (“ZZ” of U.S.G.S.) were calculated with
mean ZZ flows and mean South Bog Stream concentrations at station B-l
Note that though the Gull Pond outlet stream was sampled at station E-l
there are no flow data for that site, and nutrient loads could not be cal-
culated.
* Based on sampling frequency and variations in concentrations, sincile
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.

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 o1igotrophic or becoming oligo-
trophic if morphometry permitted. A niesotrophic rate would
be considered one between “dangerous” and “permissible”.
Total Phosphorus Total Nitrogen
Units Total Accumulated Total Accumulated
lbs/acr /yr 0.8 0.4 35.1 15.5
grams/rn /yr 0.09 0.04 3.93 1.74
Vollenweider loading rates for phosphorus
(g/m 2 /yr) based on the mean depth and mean
hydraulic retention time of Rangeley Lake:
“Danqerous” (eutrophic rate) 0.44
“Permissible” (oligotrophic rate) 0.22
-------
13
F. Controllability of Nutrients:
1. Discussion —
During the sampling year, Rangeley Lake received a total
phosphorus load at a rate less than half that proposed by
Vollenweider as permissible (i.e., an oligotrophic rate).
About 78% of the load was contributed by non-point or areal
sources, and the community of Rangeley contributed about 15%
via Haley Pond. It is estimated that camp and home septic tanks
around the lake contributed about 7%.
Since the Rangeley waste treatment plant discharges effluent
to Haley Pond, some portion of the total phosphorus load from
the plant would be expected to be sedimented and/or biologically
assimilated in the Pond. To determine what proportion of the
total load probably reached Rangeley Lake, the following ration-
ale was applied.
It is calculated that 870 lbs. of phosphorus were dis-
charged from the treatment plant during the sampling year. Areal
contributions to Haley Pond were estimated by deriving the mean
annual P-load, in lbs/mi 2 /yr, from all of the other tributaries
sampled and multiplying this mean value by the drainage area of
Haley Pond (in mi 2 ). Areal contributions thus determined were
290 lbs/yr.
The sum of point-source and areal contributions to the Pond,
then, totaled 1,160 lbs. However, during the sampling year,
-------
14
only 970 lbs were measured leaving Haley Pond at station D-l
or 84% of that contributed by all sources. Therefore, the
phosphorus loads attributed to the Haley Pond outlet and the
Rangeley treatment plant (see phosphorus loading, page 9) are
values adjusted for the 16% of these loads estimated to have
remained in Haley Pond.
The phosphorus removal facilities to be added to the Rangeley
waste treatment plant should help preserve the existing excellent
quality of Rangeley Lake. The planned 95% phosphorus removal will
result in about a 71% reduction of phosphorus loading to 170-acre
Haley Pond as well as a significant reduction in the localized
loading rate to City Cove of Rangeley Lake. Furthermore, the
improvement in trophic condition of Haley Pond should reduce
the occurrence of algal blooms there and the resulting aes-
thetically unpleasant green plumes of algae in City Cove.
At present, septic tank contributions may not be a problem.
H’owever, because the soils in the area prevent effective ab-
sorption of tank effluents, and because shoreline developments
are expected to increase, consideration should be given to
future control of these nutrient sources to further protect
the quality of Rangeley Lake.
