Assessment Comments

Previous assessment was based on results of DNR stream use assessment in September 1995; no recent water quality information. See attached document for details.

Basis for Assessment

SUMMARY: The Class B(WW) aquatic life uses are assessed as "fully supported." The fish consumption uses remain "not assessed." EXPLANATION: Upon review of the assessment of support for the Class B(WW) uses developed for the 1998 report (see above), this assessment was upgraded to "fully supported" for the 2000 report. According to DNR's assessment methodology for Section 305(b) reporting, the results of the September 1995 DNR stream use assessment suggest "full support" of the Class B(WW) uses. The fish consumption uses remain "not assessed" due to the lack of recent fish tissue monitoring data for this river reach.
