Assessment Comments
Habscr/fshscr: 25/10 (seine) (score corrected due to error in scoring % pollution tolerant species); 1997 Biocriteria: Fish IBI=51 (good), BM-IBI=74 (good).
Basis for Assessment
The assessment was based on the 1997 data and the aquatic life use support continued to be assessed as fully supporting (=FS), 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.
