FOREWORD
The National Eutrophication Survey was initiated in 1972 in
response to an Administration commitment to investigate the nation-
wide threat of accelerated eutrophicaticn 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 or: selected freshwater lakes as a basis for
formulating comprehensive and coordinated national, regional, and
state management practices relating to point source discharge
reduction and nonpolnt source pollution abatement in lake water-
sheds.
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 reports 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
[§303(c)]9 clean lakes [§314(a,b)]s and water quality monitoring
[§106 and §305(b)] activities mandated by the Federal Water
Pollution Control Act Amendments of 1972.
-------
111
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 THEODORE ROOSEVELT LAKE, ARIZONA
STORET NO. 0410
I. CONCLUSIONS
A. Trophic Condition:*
Survey data indicate that Theodore Roosevelt Lake is
mesotrophic. Chlorophyll a^ values in the lake ranged from
2.3 yg/1 to 5.7 yg/1, with a mean of 4.1 yg/1. Potentials
for primary production as measured by algal assay control
yields were moderately low except at Stations 03-05 in
November when the yield was relatively high. Of the 11
Arizona Lakes' sampled in 1975, 7 had higher median total
phosphorus values, (0.020 mg/1), 9 had higher median in-
organic nitrogen levels (0.040 mg/1), and 7 had higher
median orthophosphorus levels (0.008 mg/1) than Theodore
Roosevelt Lake.
Survey limnologists did not observe any problem algal
blooms or macrophyte growths in the lake during the sampling
year.
*See Appendix E.
-------
B. Rate-Limiting Nutrient:
The algal assay results indicate that primary production
in Theodore Roosevelt Lake was limited by available phosphorus
levels. The lake data suggest primary limitation in the lake
by nitrogen on all sampling occasions.
C. Nutrient Controllability:
1. Point sources -
During the sampling year, the listed point sources
were calculated to have contributed 11.9% of the total
phosphorus load to Theodore Roosevelt Lake; 8.8% of the
annual total was calculated to be contributed by the
city of Globe. However, this loading estimation may be
excessively high, since the Arizona Department of Health
Services (W.H. Shafer, Personal Communication) indicates
much of the effluent from Globe is used for irrigation
and thus may not reach the lake in undiminished form.
The remaining phosphorus point source load was attributable
to six smaller sewage treatment facilities, with the city
of Miami and the Miami High School contributing 1.4% each
to the total phosphorus contribution.
In addition, there are two fish hatcheries located
upstream on Canyon and Tonto Creeks which are known to
impact Roosevelt Lake. During the 1975 sampling year, the
-------
operators of these fish hatcheries provided monthly dis-
charge chemistry samples and flow data which reveal that
the Canyon Creek Fish Hatchery contributed 1,145 kg P
and the Tonto Creek Fish Hatchery contributed 595 kg P/yr
to their respective tributary waters. However, both
hatcheries are located considerably further away from
Roosevelt Lake than 40 stream km (25 miles), and for this
reason are not included in the lake nutrient budget on
pages 15-16, The Canyon Creek Fish Hatchery contributions
are included in the nutrient loadings to the lake from
Station A-2, Salt River.
The present phosphorus loading of 2.08 g P/nrVyr is
three times that proposed by Vollenweider (1975) as "eutrophic"
for a lake of such volume and retention time. Vollenweider's
models, however, is not applicable to a lake with fluctuating
volume such as Theodore Roosevelt Lake. Drawdown occurs
yearly for downstream irrigation and power purposes
(W.H. Shafer, Personal Communication). Additional sampling
is needed to better define the nutrient budget of the
lake before recommendations on controllability can be proposed.
2. Nonpoint sources -
Nonpoint sources, including precipitation, contributed
88.1% of the total phosphorus input to Theodore Roosevelt
-------
Lake during the sampling year. The Salt River contributed
82.8% and minor tributaries and ungaged drainage areas were
estimated to have contributed 4.5% of the total.
o
The phosphorus export rate of Salt River (9 kg P/knr/yr)
compares favorably with the tributary export rates of nearby
San Carlos Reservoir* (8-15 kg P/km2/yr).
*See Working Paper No. 736.

II. LAKE AND DRAINAGE BASIN CHARACTERISTICS
Lake and drainage basin characteristics are itemized below.
Lake morphometry data were provided by Ned L. Rathbun, (1974);
average surface area and maximum volume at spillway are indicated.
Tributary flow data were provided by the Arizona 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.

III. LAKE WATER QUALITY SUMMARY
Theodore Roosevelt Lake was sampled three times during the
open-water season of 1975 by means of a pontoon-equipped Huey heli-
copter. Each time, samples for physical and chemical parameters
were collected from five stations on the lake and from a number
of depths at each station (see map, page v). During each visit,
depth-integrated samples were collected from each station for chloro-
phyll £ analysis and phytoplankton identification and enumeration.
During the first and last visits, 18.9-liter depth-integrated
samples were composited for algal assays. Maximum depths sampled
were 17.7 meters at Station 01, 23.8 meters at Station 02, 43.0
meters at Station 03, 38.7 meters at Station 04, and 15.2 meters
at Station 05. 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 chloro-
phyll £ 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 capricornutum*.
indicate that the potential for primary production in Theodore Roose-
velt Lake was moderately low on both sampling occasions (03/05/75,
11/18/75) except at Stations 03-05 during November, when it was
relatively high. In all assays, the addition of phosphorus spikes
alone resulted in a significant increase in yield over that of the
control, indicating primary limitation by phosphorus in the lake.
In all assays the addition of nitrogen alone did not produce a growth
response, and the maximum increase in yield over that of the control
was achieved with the simultaneous addition of both phosphorus and
nitrogen spikes.
The mean inorganic nitrogen to orthophosphorus ratios (N/P) in
the lake data were approximately 12/1 or less on all sampling occasions,
suggesting primary limitation by nitrogen.
*For further information regarding the algal assay test procedure
and selection of test organisms, see U.S. Environmental Protection
Agency (1971).

IV. NUTRIENT LOADINGS
(See Appendix D for data)
For the determination of nutrient loadings, the Arizona 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. Samp-
ling 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 provided by
the Arizona District Office of the USGS for the tributary 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 tributaries
are those measured minus known point source loads, if any.
Nutrient loadings for unsampled "minor tributaries and immediate
drainage" ("II" of USGS) were estimated by using the mean annual con-
centrations in Salome Creek at Station G-l and mean annual II flow.
The operators of the Globe, Miami Inspiration Hospital, Cobre
Valley Shopping Center and Hoi gate wastewater treatment plants pro-
vided monthly effluent samples and corresponding flow data. Nutrient
loads for the Miami Municipal, Miami High School, and Roosevelt Marina
wasteweter treatment plants were calculated using provided monthly
chemistry data and estimated flows.

F. 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 ARIZONA
Mean or median values for six of the key parameters evaluated
1n establishing the trophic conditions of Arizona 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 1n mg/1. Chlorophyll a_ values are expressed 1n 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.
