Assessment Comments

Assessment is based on results of a September 1995 DNR stream use assessment.

Basis for Assessment

SUMMARY:  The Class B(WW) aquatic life uses remain assessed as "fully supported / threatened."  Fish consumption uses remain "not assessed."  EXPLANATION:  Continue to use the assessment of support of the Class B(WW) uses developed for the 1998 report (see above).   The results of the September 1995 DNR stream use assessment in Hancock County-upon which the previous (1998) assessment was based-are approximately 5 years old and thus can be used to assess current water quality conditions.   Fish consumption uses remain "not assessed" due to the lack of fish tissue monitoring in this river reach.
