Assessment Comments
Assessment based on results of IDNR biocriteria monitoring in 1994.
Basis for Assessment
Used data from 1994 biocriteria site in Johnson County to update use support determination. Fish and habitat metrics from stream use assessment protocol were applied to the data. Habitat quality was fairly good. A lot of snag habitat and diversity of current and depth in reach sampled. Water clarity was poor at time of sampling making it difficult to catch fish. Reasonably good diversity of fish for B(LR) stream including channel catfish, gar and walleye.
