Pottawatomie State Fishing Lake Assessment
|Date||January 2008 - December 2008|
|Location||Pottawatomie State Fishing Lake, Kansas|
Pottawatomie State Fishing Lake is currently listed under the draft KDHE 2008 303(d) List as a water-quality impaired reservoir. There is a need to monitor current water-quality conditions of this lake to examine impairment status, i.e., if impairment persists, a total maximum daily load (TMDL) has to be developed for this lake by KDHE, as required by the Clean Water Act. In addition to the three sampling sites at the lake, the two tributaries of the lake will also be sampled for nutrient and chlorophyll a analyses from July to September. Autosamplers will be installed at the two tributaries to collect water samples during storm events.
The objectives of this project are:
1. Assess current trophic conditions (i.e., nutrient and chlorophyll a levels);
2. Determine incoming nutrient load via tributary baseflow water-quality monitoring and autosampler installation at the two tributaries to collect runoff water samples;
3. Determine limiting nutrient(s) via laboratory bioassay experiments.

Bioassay of a water sample was collected at the main basin (site 3) on 9/22/2008. Experiment started on 9/23/2008.
