Assessment Comments
May 1991 SUA: habscr/fishscr= 23/10 (shock) . 1997 Biocriteria: Fish IBI= 55(good), BM-IBI= 59(good).
Basis for Assessment
The assessment was based on data collected in 1997 as part of the DNR/UHL stream biocriteria project. A series of biological metrics which reflect stream water quality and habitat integrity were calculated from the biocriteria sampling data. The biological metrics are based on the numbers and types of benthic macroinvertebrate taxa and fish species that were collected in the stream sampling reach. The biological metrics were combined to make a fish community index of biotic integrity (F-IBI) and a benthic macroinvertebrate index (BM-IBI). The indexes rank the biological integrity of a stream sampling reach on a rising scale from 0 (minimum) to 100 (maximum).
