FOREWORD
The National Eutroph1cat1on Survey was Initiated 1n 1972 1n
response to an Administration commitment to Investigate the nation-
wide threat of accelerated eutrophlcation to freshwater lakes and
reservoirs.
OBJECTIVES
The Survey was designed to develop, in conjunction with state
environmental agencies, information on nutrient sources, concen-
trations, 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 nonpoint source pollution abatement in lake water-
sheds.
ANALYTIC APPROACH
The mathematical and statistical procedures selected for the
Survey's eutrophlcation 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 eutrophlcation control can be made.
LAKE ANALYSIS
In this report, the first stage of evaluation of lake and
watershed 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
l§303(c)], clean lakes [§314(a,b)]t and water quality monitoring
[§106 and §305(b)] activities mandated by the Federal Water
Pollution Control Act Amendments of 1972.
-------
iii
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 refine-
ment of nutrient water quality criteria for the Nation's freshwater
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 the U.S. Environmental Protection
Agency and to augment plans implementation by the states.

I. INTRODUCTION
Diamond Lake was included in the National Eutrophication Survey as
a water body of interest to the Washington State Department of Ecology.
The outlet was the only stream sampled, and this report relates only to
lake sampling data. However, the outlet data (Moon Creek) are included
in Appendix C for the record.
Diamond Lake is a natural water body located in northeastern
Washington near the city of Newport. A popular recreation site, the
shoreline is almost entirely surrounded by dwellings and commercial
establishments. Good catches of rainbow trout, cutthroat trout, and
crappies are maintained by periodic stocking. Some phytoplankton problems
have been reported in the past (Wolcott, 1973; Cline, 1975; Millenbach,
1975).
II. CONCLUSIONS
A. Trophic Condition*:
Survey data indicate that Diamond Lake is eutrophic. It
ranked eighth in overall trophic quality among the 13 Washington
lakes and reservoirs sampled in 1975 when compared using a com-
bination of six water quality parameters**. Four of the water
bodies had less and one had the same median total phosphorus,
nine had less median orthophosphorus, three had less median
* Trophic assessment is based on the levels of nutrients, dissolved-
oxygen, and chlorophyll a_; phytoplankton kinds and numbers; and
transparency (Allurn et al., 1977).
** See Appendix A.

inorganic nitrogen, ten had less mean chlorophyll a^, and
three had greater mean Secchi disc transparency. Depression of
hypolimnetic dissolved oxygen occurred at station 2 in July and
September.
Survey limnologists noted submerged macrophytes throughout
the lake and emergent vegetation along much of the shoreline.
The relatively high chlorophyll a_ levels at station 1 in July
and September (page 7) further indicate an enriched condition.
B. Rate-Limiting Nutrient:
The algal assay results indicate Diamond Lake was phos-
phorus limited at the time the sample was collected (10/24/75).
The lake data indicate phosphorus limitation in September and
October but nitrogen limitation in June and July.

IV. WATER QUALITY SUMMARY
Diamond Lake was sampled four 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 lake (see map, page v). During the first
three visits, 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 last visit, a single 18.9-liter depth-inte-
grated 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 7.6 meters at station 1 and
15.5 meters at station 2.
The sampling results are presented in full in Appendix C and are sum-
marized in the following table.

2. Discussion -
The control yield of the assay alga, Selenastrum capri-
cornutum, indicates that the potential primary productivity
of Diamond Lake was moderate at the time the sample was col-
lected (10/24/75). Also, the significant increase in yield
with the addition of orthophosphorus alone indicates the lake
was phosphorus limited at that time. Note that the addition
of nitrogen alone resulted in a yield no greater than that of
the control.
The lake data indicate phosphorus limitation in September
and October (the mean inorganic nitrogen/orthophosphorus
ratios were 20/1 or greater). However, nitrogen limitation
is indicated in June and July; i.e., the mean N/P ratios
were 11/1 or less, and nitrogen limitation would be expected
(N/P ratios of 14/1 or greater generally indicate phosphorus
limitation).
