Assessment Comments

No water quality monitoring conducted.

Basis for Assessment

SUMMARY:  The Class B(WW) aquatic life uses were considered "not assessed."  Fish consumption uses remain "not assessed."  EXPLANATION:  The assessment of support of the Class B(WW) uses developed for previous reports (see above) was based, in part, on results of DNR quarterly water quality monitoring near Turin (station 911090).   Data from this station, however, were last collected from October 1993 through September 1995 and are thus considered too old (greater than five years) for characterizing current water quality conditions.   Thus, the assessment of support of the Class B(WW) aquatic life uses was changed from "partially supported" to "not assessed."  As part of DNR's expanded water quality monitoring program, monthly monitoring at the Turin station began in October 1999.   Results from this monitoring will allow development of an updated assessment of support of beneficial uses for the 2002 report.   Previous assessments were also based on results from a DNR stream use assessment in October 1995 (see assessments for the 1996 and 1998 reports above).   The habitat evaluation conducted for this assessment is now considered insufficient for determining support of aquatic life uses.   Fish consumption uses remained "not assessed" due to the lack of fish tissue monitoring in this river reach.
