FOREWORD
The National Eutrophication Survey was Initiated 1n 1972 in
response to an Administration commitment to investigate the nation-
wide threat of accelerated eutrophication to fresh water 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(cJ], clean lakes [S314(a,b)],
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 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.

RHODHISS LAKE
STORET NO. 3715
I. CONCLUSIONS
A. Trophic Condition:
Survey data show that Rhodhiss Lake is eutrophic. However,
because the lake has a mean hydraulic retention time of only 21
days, it more closely resembles a slow-moving stream; and the
term "over-enriched" may be a more appropriate description of
the lake condition.
Rhodhiss Lake ranked ninth in overall trophic quality when
the 16 North Carolina lakes sampled in 1973 were compared using
/
a combination of six parameters*. Twelve of the lakes had less
median total phosphorus, 13 had less median dissolved phosphorus,
five had less median inorganic nitrogen, but only one of the
lakes had less mean chlorophyll a^ The relatively low concen-
trations of chlorophyll a^ and the high nutrient levels indicate
primary productivity probably was light-limited. Ten of the lakes
had greater mean Secchi disc transparency, and Survey limnologists
noted that the water was turbid each sampling time.
Depression of dissolved oxygen with depth occurred at
sampling stations 2 and 3 in July and September. Station 1 was
not sampled at depths greater than 1.5 meters.
* See Appendix A.
-------
B. Rate-Limiting Nutrient:
The algal assay results show that Rhodhiss Lake was nitro-
gen limited at the time the assay sample was collected (03/30/73).
The lake data indicate nitrogen limitation in March and September
at station 2, and in September at station 3; i.e., the N/P ratios
were 11/1 or less at those times. At the other stations and
sampling times, the lake data indicate phosphorus limitation (the
N/P ratios were greater than 14/1, and phosphorus limitation
would be expected).
C. Nutrient Controllability:
1. Point sources—A minimum of 20.3% of the total annual
phosphorus load to Rhodhiss Lake was contributed by point sources.
Lenoir contributed 8.2% of the total, and Morganton contributed
7.6%.
The phosphorus loads of all of the known municipal point sources
were estimated because none of the communities participated in the
sampling program, and it is believed that most of these estimates
are much too low. Note that the "non-point" export rates of
Hunting Creek, Hoyle Creek, and McGalliard Creek were many times
higher than the rates of the other Rhodhiss Lake tributaries (see
page 16). These very high export rates and the very low export
N/P ratios (3/1 or less) are indicative of a marked underestimation
of point-source phosphorus loads.
-------
If the mean of the phosphorus export rates of unimpacted
Bristol, Freemason, Smoky, and Stafford creeks and the Johns
River (24 kg/km2/yr) is assumed to be a typical non-point
export rate for streams in the Rhodhiss Lake drainage, and the
point-source phosphorus contributions to Howard, Hoyle, Hunting,
and McGalliard creeks are calculated accordingly, the point-source
phosphorus input to the lake would be 59% of the total load rather
than a little over 20%. Further study is needed to determine the
actual point-source impact on Rhodhiss Lake.
During the sampling year, Rhodhiss Lake received a total
phosphorus load at a rate seven times that proposed by Vollenweider
(Vollenweider and Dillon, 1974} as a eutrophic rate (see page 17).
However, the mean hydraulic retention time of the lake is only
21 days, and Vollenweider's model may not be applicable. Nonethe-
less, it is likely that a high degree of point-source phosphorus
control would result in persistent phosphorus limitation through-
out Rhodhiss Lake (see page 11) and would reduce the present rate
of eutrophication. Such control probably would also benefit down-
stream Lake Hickory (Working Paper No. 380).
2. Non-point sources—It is calculated that 31.5% of the
non-point source phosphorus load was contributed to Rhodhiss Lake
by the Catawba River, whereas the Johns River with a drainage
-------
area about one-third of that of the Catawba River, contributed
only one-ninth as much phosphorus.
As mentioned above, the phosphorus export rates of Hunting
Creek, Hoyle Creek, and McGilliard Creek were much too high and
probably were due to point sources.

III. LAKE WATER QUALITY SUMMARY
Rhodhiss Lake was sampled three times during the open-water season
of 1973 by means of a pontoon-equipped Huey helicopter. Each time,
samples for physical and chemical parameters were collected from
three stations on the lake and from one or more depths at each station
(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 first
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 1.5 meters at station 1, 10.7 meters at station 2,
and 14.6 meters at station 3.
The lake sampling results are presented in full in Appendix D and
are summarized in the following table.

The control yield of the assay alga, Selenastrum capri-
cornutum, indicates that the potential primary
productivity
of Rhodhiss Lake was high at the time the assay sample was
collected (03/30/73). Also, the lack of increase in yield
with increasing concentrations of orthophosphorus along with
a significant increase in yield with the addition of only
-------
11
nitrogen indicate that the lake was nitrogen limited at
that time.
The lake data indicate a combination of limiting nutrients.
Station 2, which was close to point-source nutrient inputs,
was nitrogen limited in March and September, but all three
stations were phosphorus limited in July.
Following is a tabulation of the mean inorganic nitrogen
to orthophosphorus ratios for each of the stations and samp-
ling times with the indicatedlimiting nutrient in parenthesis.
Station 03/30/73 07/06/73 09/24/73

02 11/1 (N) 34/1 (P) 7/1 (N)
03 15/1 (P) 31/1 (P) 10/1 (N)
Nitrogen limitation, as indicated by the algal assay
or by the in-lake nitrogen to phosphorus ratios, does not
necessarily suggest that the trophic condition of the lake
can be improved by controlling nitrogen inputs. In the
majority of cases, phosphorus is still the element to be
controlled. The apparent condition of nitrogen-limitation
frequently results from excessive phosphorus input from
point sources (e.g., station 2) and is often accompanied by
a corresponding increase in primary production. The reversal
of the enriched condition, therefore, depends upon phosphorus
control, not nitrogen control.

IV. NUTRIENT LOADINGS
(See Appendix E for data)
For the determination of nutrient loadings, the North Carolina
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 January and February when two samples were col-
lected. Sampling was begun in March, 1973, and was completed in
February, 1974.
Through an interagency agreement, stream flow estimates for the
year of sampling and a "normalized" or average year were provided by
the Nqrth Carolina District Office of the U.S. Geological Survey for
the tributary sites nearest the lake.
In this report, nutrient loads for sampled tributaries were deter-
mined by using a modification of a U.S. Geological Survey computer
program for calculating stream loadings*. Nutrient loads shown are
those measured minus point-source loads, if any.
Nutrient loads for unsampled "minor tributaries and immediate
drainage" ("II" of U.S.G.S.) were estimated using the means of the
nutrient loads, in kg/km2/year, at stations F-l, G-l, H-l, and J-l
and multiplying the means by the II area in km2.
The communities of Drexel, Lenoir, Valdese, Marion, and Morganton
did not participate in the sampling program, and nutrient loads were
estimated at 1.134 kg P and 3.401 kg N/capita/year.

E. Yearly Loading Rates:
In the following table, the existing phosphorus loading
rates are compared to those proposed by Vollenweider (Vollen-
weider and Dillon, 1974). Essentially, his "dangerous" rate
is the rate at which the receiving water would become eutrophic
or remain eutrophic; his "permissible" rate is that which would
result in the receiving water remaining oligotrophic or becoming
oligotrophic if morphometry permitted. A mesotrophic rate would
be considered one between "dangerous" and "permissible".
Note that Vollenweider's model may not be applicable to
'water bodies with short hydraulic retention times.
