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, 1n 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 1s formatted to provide state
environmental agencies with specific Information for basin
! Tanning [§303(e)], water quality criteria/standards review
§303(cJ], clean lakes [§314(a,bj], 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 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 1n the formulation of
planning guidelines and policies by the U.S. Environmental Protection
Agency and to augment plans implementation by the states.

REPORT ON EAGLE NEST LAKE, NEW MEXICO
STORET NO. 3504
I. CONCLUSIONS
A. Trophic Condition:*
Based on Survey data and field observations, Eagle Nest
Lake is considered eutrophic, i.e., nutrient rich and highly
productive. Whether such nutrient enrichment is to be con-
sidered beneficial or deleterious is determined by its actual
or potential impact upon designated beneficial water uses of
the lake.
Chlorophyll a_ values in the lake ranged from 2.2 yg/1
in August to 37.4 yg/1 in October with a mean of 13.4 yg/1.
Secchi disc visibility was low and the potential for primary
productivity as measured by algal assay control yields was
high. Of the nine New Mexico lakes (including Navajo Reser-
voir) sampled in 1975, none had higher median total phos-
phorus levels (0.181 mg/1), four had higher median inorganic
nitrogen levels (0.070 mg/1), and none had higher median
orthophosphorus values (0.132 mg/1) than Eagle Nest Lake.
Survey limnologists reported algal blooms on both the
August and October sampling dates.
*See Appendix E.
-------
B. Rate-Limiting Nutrient:
The algal assay results suggest that Eagle Nest Lake was
limited by available nitrogen during both sample collection times
(05/06/75, 10/07/75). The lake data further suggest primary
limitation by nitrogen.
C. Nutrient Controllability:
1. Point sources -
There were no known point sources impacting Eagle Nest
Lake during the sampling year. The present phosphorus
9
loading of 0.27 g P/m /yr is equal to that proposed by Vollen-
weider as "eutrophic" for a lake of such volume and retention
time. Examination of land use practices may provide answers
for reducing the nutrient input to the lake.
2. Nonpoint sources -
Moreno Creek contributed 47.3% of the total phosphorus
load to Eagle Nest Lake during the sampling year. Cieneguilla
Creek contributed 25.9%, Sixmile Creek contributed 6.8% and
minor tributaries and immediate drainage contributed an
estimated 13.5%.
-------
II. LAKE AND DRAINAGE BASIN CHARACTERISTICS
Lake and drainage basin characteristics are itemized below.
Lake morphometry data were provided by Martin and Hanson (1966)
and Tony Drypolcher (personal communication). Tributary flow
data were provided by the New Mexico District Office of the U.S.
Geological Survey (USGS). Outlet drainage area includes the lake
surface area. Mean hydraulic retention time was obtained by
dividing the lake volume by mean flow of the outlet. Precipi-
tation values are estimated by methods as outlined in National
Eutrophication Survey (NES) Working Paper No. 175. A table of
metric/English conversions is included as Appendix A.
A. Lake Morphometry:
1. Surface area: 9.82 km2.
2. Mean depth: 9.9 meters.
3. Maximum depth: 31.1 meters.
4. Volume: 97.954 x 10^ m3.

III. LAKE WATER QUALITY SUMMARY
Eagle Nest Lake 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 col-
lected from three stations on the lake (Station 03 was sampled
only twice) and from one or more depths at each station (see map,
page v). During each visit, depth-integrated samples were col-
lected from each station for chlorophyll a_ analysis and phyto-
plankton identification and enumeration. During the first and
last visits, 18.9-liter depth-integrated samples were composited
for algal assays. Maximum depths sampled were 12.5 meters at
Station 01, the surface at Station 02, and 7.6 meters at Station
03. For a more detailed explanation of NES methods, see NES
Working Paper No. 175.
The results obtained are presented in full in Appendix C
and are summarized in III-A for waters at the surface and at the
maximum depth for each site. Results of the phytoplankton counts
and chlorophyll ^determinations are included in III-B. Results
of the limiting nutrient study are presented in III-C.

2. Discussion -
The control yields of the assay alga, Selenastrum capricor-
nutum, indicate that the potential for primary productivity in
Eagle Nest Lake was high at both sample collection times (05/06/75*
10/07/75). In both assays, a significant increase in yield over
that of the control occurred when nitrogen was added alone and in
combination with phosphorus, indicating nitrogen limitation.
Spikes of phosphorus alone resulted in a yield which was not sig-
nificantly greater than that of the control.
The mean inorganic nitrogen to orthophosphorus ratios (N/P)
in the lake data were approximately 1/1 or less on all three
sampling occasions further suggesting primary limitation by nitrogen
(a mean N/P ratio of 14/1 or greater generally reflects phosphorus
limitation).
-------
11
IV. NUTRIENT LOADINGS
(See Appendix D for data)
For the determination of nutrient loadings, the New Mexico
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. Sampling was begun in December 1974, and was completed
in October 1975.
Through an interagency agreement, stream flow estimates for
the year of sampling and a "normalized" or average year were pro-
vided by the New Mexico District Office of the USGS for the tribu-
tary sites nearest the lake.
In this report, nutrient loads for sampled tributaries were
determined by using a modification of a USGS computer program for
calculating stream loadings. Nutrient loads indicated for tribu-
taries are those measured minus known point source loads, if any.
Nutrient loadings for unsampled "minor tributaries and imme-
diate drainage" ("II" of USGS) were estimated by using the mean
2
annual nutrient loads, in kg/km /year, in Moreno Creek, Sixmile
Creek and Cieneguilla Creek, at Stations B-l, C-l, and D-l and
2
multiplying the means by the II area in km.

E. Yearly Loadings:
In the following table, the existing phosphorus annual
loading is compared to the relationship proposed by Vollenweider
(1975). Essentially, his "eutrophic" loading is that at which
the receiving waters would become eutrophic or remain eutrophic;
his "oligotrophic" loading is that which would result in the
receiving water remaining oligotrophic or becoming oligotrophic
if morphometry permitted. A "mesotrophic" loading would be
considered one between eutrophic and oligotrophic.
Note that Vollenweider's model may not apply to lakes with
short hydraulic retention times or in which light penetration is
severely restricted by high concentrations of suspended solids
in the surface waters.

APPENDIX E
PARAMETRIC RANKINGS OF LAKES
SAMPLED BY NES IN 1975
STATE OF NEW MEXICO
Mean or median values for six of the key parameters evaluated
in establishing the trophic conditions of New Mexico lakes sampled
are presented to allow direct comparison of the ranking, by parameter,
of each lake relative to the others. Median total phosphorus,
median inorganic nitrogen and median dissolved orthophosphorus
levels are expressed in mg/1. Chlorophyll a, values are expressed
in yg/1. To maintain consistent rank order with the preceding
parameters, the mean Secchi disc depth, in inches, is subtracted
from 500. Similarly, minimum dissolved oxygen values are subtracted
from 15 to create table entries.
