Assessment Comments
Assessment based on results of IDNR/UHL biological (biocriteria) monitoring in 2001: FIBI = 34 (fair), BMIBI = 67 (good). FIBI BIC = 36, BMIBI BIC = 61.
Basis for Assessment
SUMMARY: The Class B(LR) aquatic life uses are assessed (monitored) as "fully supported" based on results of IDNR/UHL biological (biocriteria) sampling in 2001.
EXPLANATION: This assessment was based on data collected in 2001 as part of the DNR/UHL stream biocriteria project. The 2001 FIBI score was 34 (fair) and the BMIBI score was 67 (good). The aquatic life use support was assessed as fully supported (= FS), based on a comparison of the FIBI and BMIBI scores with biological impairment criteria (BIC) established for previous Section 305(b) reports. The biological impairment criteria were determined from a statistical analysis of data collected at stream ecoregion reference sites from 1994-2004. The FIBI BIC for this ecoregion is 36 and the BMIBI BIC for this ecoregion is 51.
