LAKE MEREDITH
STORE! NO. 0810
I. INTRODUCTION
Accurate flow data could not be provided for Lake Meredith by the
U.S. Geological Survey because water enters and leaves the lake through
ungaged inlet and outlet canals. Therefore, this report primarily pertains
to the lake sampling data. However, tributary and wastewater treatment
plant samples were collected, and the results of the analyses are pre-
sented in Appendix D.
II. CONCLUSIONS
A. Trophic Condition:
Survey data indicate Lake Meredith is eutrophic. It ranked
last in overall trophic quality when the 13 Colorado lakes and
reservoirs sampled in 1975 were compared using a combination of
six parameters*. Ten of the water bodies had less median total
phosphorus and dissolved orthophosphorus, nine had less median
inorganic nitrogen, 12 had less mean chlorophyll <^, and ten had
greater mean Secchi disc transparency.
Very high numbers of phytoplankton occurred in the August
and October samples (see page 5).
[}. Rate-Limiting Nutrient:
The algal assay results indicate the primary productivity of
Lake Meredith was limited by nitrogen at the time the sample was
collected (10/07/75). The lake data indicate nitrogen limitation
on all sampling dates.

IV. LAKE WATER QUALITY SUMMARY
Lake Meredith was sampled three times during the open-water season
of 1975 by means of a pontoon-equipped Huey helicopter. Each time,
near-surface samples for physical and chemical parameters were collected
from three stations on the lake (see map, page v). During each visit,
a single depth-integrated (near bottom to surface) sample was composited
from the stations for phytoplankton identification and enumeration;
and during the October 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 chloro-
phyll a_ analysis.
The sampling results are presented in full in Appendix C and
are summarized in the following table.

2. Discussion -
The control yield of the assay alga, Selenastrum capri-
cornutum, indicates that the potential primary productivity
of Lake Meredith was very high at the time the sample was
collected (10/07/75). Also, the addition of nitrogen alone
and in combination with phosphorus resulted in significant
increases in yield which indicates the lake was nitrogen
limited at that time. Note that the addition of phosphorus
alone resulted in a yield not significantly greater than
that of the control.
The lake data substantiate nitrogen limitation. The
mean inorganic nitrogen to orthophosphorus ratios were 3
to 1 or less at all sampling times.
