Assessment Comments
1997 Biocriteria: Fish IBI=19 (poor), 39 (fair); BM-IBI= 48 (fair), 57 (good).
Basis for Assessment
The assessment was based on the 1997 biological assessment data (see 2000 assessment comments) and the aquatic life use support continued to be assessed as partially supporting (=PS), based on a comparison of the F-IBI and BM-IBI scores with 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.
