FOREWORD
The National EutropMcatlon 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 agenc1ess 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 1n 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 eutrophication control can be made.
LAKQNAkYSIS
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
plannina [§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 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.

REPORT ON ALAMOGORDO RESERVOIR, NEW MEXICO
STORET NO. 3501
I. CONCLUSION
A. Trophic Condition:*
Based upon Survey data, Alamogordo Reservoir is considered
early eutrophic. However, biological response as measured
by chlorophyll a_ values (range of 1.9 yg/1 to 10.7 yg/1, mean
of 5.9 yg/1) is more typical of that observed in mesotrophic
water bodies. Potential for primary production as measured
by algal assay control yield was moderate in the lake samples.
Nutrient levels in the lake were moderately high: of the nine
New Mexico lakes sampled in 1975 (including Navajo Reservoir),
six had higher median total phosphorus levels (0.025 mg/1),
five had higher median inorganic nitrogen values (0.050 mg/1),
and eight had higher median orthophosphorus levels (0.003 mg/1)
than Alamogordo Reservoir.
Survey limnologists did not report any problem macrophytes
or algal growths during their visits to the lake. However, they
did note the high turbidity in the reservoir, and the low Secchi
disc visibility observed (range of 0.3 m to 1.2 m) suggests that
primary production in Alamogordo Reservoir is light- rather
than nutrient-limited. Other sources (New Mexico Water Quality
Control Commission, 1975) report that there is no permanent
*See Appendix E.
-------
pool in this lake which is used for irrigation in the Carlsbad area,
and that lake drawdown periodically results in moderate fish kills.
B. Rate-Limiting Nutrient:
Algal assay results indicate that Alamogordo Reservoir was
limited by available phosphorus levels during the fall sampling
period. The lake data suggest primary limitation by phosphorus in
the summer and fall, and nitrogen limitation during spring.
C. Nutrient Controllability:
1. Point sources -
During the sampling year, a single point source, the city
of Santa Rosa, contributed 9.3% of the total phosphorus load
to Alamogordo Reservoir.
2
The calculated annual phosphorus loading of 1.52 g P/m /yr
for the reservoir is approximately four times that proposed by
Vollenweider (1975) as "eutrophic" for a lake with such volume
and hydraulic retention time. Although Vollenweider's model
certainly is not applicable to a lake with fluctuating volume
such as Alamogordo Reservoir, other studies (New Mexico Water
Quality Control Commission, 1975; New Mexico Environmental
Improvement Agency, 1974) indicate that the lake is generally
considered to be nutrient rich and highly productive. Addi-
tional sampling is needed to determine whether the excessive
nutrient levels reported in these past studies are typical for
-------
Alamogordo Reservoir, and to better define the sources of nutrient
input into the lake.
2. Nonpoint sources -
Nonpoint sources, including precipitation, contributed
90.7% of the total phosphorus loading to Alamogordo Reservoir.
The Pecos River contributed 87.7% of the total loading. The
New Mexico Environmental Improvement Agency (1974) has rec-
commended a comprehensive sampling program for the Pecos River,
which drains not only the nutrient rich Upper Sonoran Region, but
also receives some irrigation return flows. They have also suggested
the need for obtaining state water rights in order to establish
a minimum pool for the reservoir.

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 the 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: 18.49 km2.
2. Mean depth: 8.1 meters.
3. Maximum depth: 19.8 meters.
4. Volume: 150.609 x 106 m3.

III. LAKE WATER QUALITY SUMMARY
Alamogordo 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 col-
lected from three stations on the lake and from a number of depths
at each station (see maps, pp.v-vi). During each visit, depth-
integrated samples were collected from each station for chlorophyll
a_ analysis and phytoplankton identification and enumeration. During
the last visit, an 18.9-liter depth-integrated sample was composited
for algal assays. Maximum depths sampled were 10.7 meters at Station
01, 7.6 meters at Station 02, and 4.6 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 yield of the assay alga, Selenastrum capn'cornutum,
indicates that the potential for primary productivity in Alamogordo
Reservoir was moderate at the sample collection time (10/02/75).
A significant increase in yield over that of the control occurred
when phosphorus was added alone and in combination with nitrogen,
indicating phosphorus limitation. Nitrogen spikes alone did not
result in an increase in growth beyond control yields.
The mean inorganic nitrogen to orthophosphorus ratios (N/P)
in the lake data were approximately 6/1, 18/1 and 25/1 in the spring,
summer and fall, respectively, suggesting primary limitation by
nitrogen in the spring and phosphorus limitation in the summer and
fall (a mean N/P ratio of 14/1 or greater generally reflects phos-
phorus limitation).

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
Stations A-l and A-2 indicated on the maps (pages v-vi), 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 November 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" ("ZZ" of USGS) were estimated by using the mean
2
annual nutrient loads, in kg/km /year in Pecos River, at Station
2
A-2 and multiplying the means by the ZZ area in km .
The operator of the Santa Rosa wastewater treatment plant
provided monthly effluent samples and corresponding flow data.

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.
