Documentation

Assessment Comments

Assessment is based on results of (1) surveys by IDNR Fisheries Bureau, and (2) ISU report on lake phytoplankton communities.

Basis for Assessment

SUMMARY: The Class A (primary contact recreation uses) were "not assessed." Continued to assess support of the Class B(LW) aquatic life uses as "partially supported." Other beneficial uses remain "not assessed." EXPLANATION: The Class A (primary contact recreation) uses were changed from "partially supporting" to "not assessed" due to the lack of information on levels of indicator bacteria at this lake. The previous (1998) assessment of support of the Class B(LW) uses ("partially supported") was reviewed and approved by the DNR Fisheries Bureau in 2000. Fish consumption uses remain "not assessed" due to the lack of fish contaminant monitoring at this lake.
