Assessment Comments

Assessment is based on results of DNR stream use assessment in 1994.

Basis for Assessment

SUMMARY:  The Class B(WW) aquatic life uses remain assessed as "fully supported / threatened" (minor impacts).   Fish consumption uses remain "not assessed."  EXPLANATION:  Continue to use the assessment of the Class B(WW) uses developed for the 1998 report (above).   This assessment was based, in part, on results of DNR stream use assessments conducted in October 1994.   The results of this assessment are approximately five years old and thus can be used to assess current water quality conditions.   Additional chemical and/or biological monitoring is needed in this assessment reach to better determine the status of water quality and the aquatic communities.   Fish consumption uses remain "not assessed" due to the lack of fish tissue monitoring in this river reach.
