Paint Creek IA 01-UIA-226
mouth (Allamakee Co.) to confluence with Little Paint Cr. in S32 T97N R3W Allamakee Co.
Assessment Comments
1994 biocriteria sampling conducted approximately 1/2 mile downstream from confluence with Little Paint Creek.
Basis for Assessment
The assessment was based on data collected in 1994 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).
The F-IBI score was 51 (good) and the BM-IBI score was 56 (good). The aquatic life use support was assessed as fully supported / threatened (=FST), based on a comparison of the F-IBI and BM-IBI scores with biological assessment criteria established specifically for the 2000 Section 305(b) report. The biological assessment criteria were determined from a statistical analysis of data collected at stream ecoregion reference sites from 1994-1998.
