Assessment Comments

Assessment is based on results of surveys by IDNR Fisheries Bureau.

Basis for Assessment

The Class A (primary contact recreation uses) remain "not assessed."  Continued to assess support of the Class B(LW) aquatic life uses as "fully supported / threatened."  Other beneficial uses remain "not assessed."  EXPLANATION:  The level of support of the Class A (primary contact recreation) uses remained "not assessed" due to the lack of swimming use at this lake (see assessment developed for the 1994 report above).   The previous (1998) assessment of support of the Class B(LW) uses ("fully supported / threatened") 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.
