Assessment Comments
Assessment is based on results of fish surveys conducted by staff/students at Lakeside Laboratory in June 1998.
Basis for Assessment
SUMMARY: The Class B(LR) aquatic life uses remain "fully supported / threatened." EXPLANATION: Continue to use the assessment developed for the 1998 report that was based on the June 1998 fish survey by students from Lakeside Laboratory. The results of the this survey are less than 5 years old and thus can be used to assess current water quality conditions.
