Assessment Comments
Assessment is based on results of IDNR/UHL biological (biocriteria) monitoring in 2001: Fish IBI=38 (fair), BM-IBI=63 (good).
Basis for Assessment
SUMMARY: The Class B(LR) aquatic life uses are assessed (monitored) as "fully supported / threatened" (minor impacts) based on results of IDNR/UHL biological (biocriteria) sampling in 2001. This is the same assessment as that developed for the 2002 reporting cycle.
EXPLANATION: This assessment was based on data collected in 2001 as part of the DNR/UHL stream biocriteria project. The 2001 Fish IBI score was 38(fair) and the BM-IBI score was 63(good). The aquatic life use support was upgraded from partially supporting (=PS) to fully supported / threatened (=FST), based on a comparison of the F-IBI and BM-IBI scores from a new sample site NE of Perry to biological assessment criteria established specifically for the 2002 Section 305(b) report. The biological assessment criteria were determined from a statistical analysis of data collected at stream ecoregion reference sites from 1994-2001.
