FOREWORD
The National Eutrophication Survey was initiated in 1972 in
response to an Administration comrnitment to investigate the nation-
wide threat of accelerated eutrophication to freshwater 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.
ACKNOWLEDGEMENT
The staff of the National Eutrophication Survey (Office of
Research & Development, U. S. Environmental Protection Agency)
expresses sincere appreciation to the Colorado Department of
Health for professional involvement, to the Colorado National
Guard for conducting the tributary sampling phase of the Survey,
and to those wastewater treatment plant operators who voluntarily
provided effluent samples.
The staff of the Water Quality Control Division provided
invaluable lake documentation and counsel during the Survey,
reviewed the preliminary reports, and provided critiques most
useful in the preparation of this Working Paper series.
Lt. Colonel Paul A. Parsons, the Deputy Adjutant General of
Colorado, and Project Officer Colonel Hershel C. Yeargan, who
directed the volunteer efforts of the Colorado National Guardsmen,
are also gratefully acknowledged for their assistance to the Survey.

I. INTRODUCTION
Accurate flow data could not be provided for Milton Reservoir
by the U.S. Geological Survey because water enters and leaves the lake
through ungaged inlet and outlet canals. Therefore, this report pri-
marily pertains to the lake sampling data. However, tributary and
wastewater treatment plant samples were collected, and the results
of the analyses are presented in Appendix D.
II. CONCLUSIONS
A. Trophic Condition:
Survey data indicate Milton Reservoir is eutrophic. It
ranked tenth in overall trophic quality when the 13 Colorado
lakes and reservoirs sampled in 1975 were compared using a com-
bination of six parameters*. Eleven of the water bodies had less
median total phosphorus, 12 had less median dissolved orthophosphorus
and inorganic nitrogen, six had less mean chlorophyll £, and six
had greater mean Seechi disc transparency.
B. Rate-Limiting Nutrient:
The algal assay results indicate the primary productivity of
Milton Reservoir was nitrogen limited at the time the sample was
collected (05/06/75). The reservoir data indicate nitrogen limi-
tation at all sampling times.

IV. WATER QUALITY SUMMARY
Milton Reservoir was sampled three times during the open-water
season of 1975 by means of a pontoon-equipped Huey helicopter. Each
time, samples for physical and chemical parameters were collected
from one or more depths at two stations on the reservoir (see map,
page v). During each visit, a single depth-integrated (4.6 m or
near bottom to surface) sample was composited from the stations for
phytoplankton identification and enumeration; and during the May
visit, a single 18.9-liter 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. The
maximum depths sampled were 6.4 meters at station 1 and 3.4 meters
at station 2.
The sampling results are presented in full in Appendix C and
are summarized in the following table.

2. Discussion -
The control yield of the assay alga, Selena strum c_aprj_-
cornutum. indicates that the potential primary productivity
of Milton Reservoir was high at the time the assay sample
was collected (05/06/75). Also, the addition of nitrogen
alone and in combination with phosphorus resulted in a sig-
nificant increase in yield which indicates the reservoir was
nitrogen limited at that time. Note that the addition of
phosphorus alone resulted in a yield not significantly greater
than that of the control.
The reservoir data substantiate nitrogen limitation. The
mean inorganic nitrogen to orthophosphorus ratios were 4 to 1
or less at all sampling times.
