Documentation

Assessment Comments

Assessment is based on results of (1) ISU lake survey, (2) surveys by IDNR Fisheries Bureau, (3) ISU report on lake plankton communities, and (4) results of U.S. EPA/IDNR fish tissue monitoring in 1997.

Basis for Assessment

SUMMARY: The Class A (primary contact recreation) uses were considered "not assessed." The Class B(LW) aquatic life uses remained assessed as "partially supported." Fish consumption uses remained "fully supported." EXPLANATION: The Class B(LW) aquatic life uses remain assessed as "partially supported" based on review and approval of the previous (1998) assessment by the DNR Fisheries Bureau in 2000. The water quality trend for this lake remains "stable." The fish consumption use remain "fully supported" based on results of EPA/DNR fish tissue (RAFT) monitoring in 1997 that showed low levels of all contaminants (see assessment for the 1998 report above).
