Assessment Comments

Assessment based on one biocriteria site

Basis for Assessment

Used data from one biocriteria site in Decatur County to update use support determination.  Fish and habitat metrics from stream use assessment protocol were applied to the data.  Data indicate reasonably good habitat for B(LR) stream and good diversity and numbers of fish including channel catfish, flathead catfish and trout-perch.  Maybe should consider B(WW) designation.
