Assessment Comments
Assessment based on 1995 biocriteria data.
Basis for Assessment
For the 1996 report: Used data from one biocriteria sampling site in Cedar Co. Habitat and fish metrics from stream use assessment protocol were used to make use support determination. Habitat quality was very good. Good diversity of fish (25 species) including channel catfish and smallmouth bass. Fish were fairly abundant, but several species only represented by a few individuals. Results of DNR stream use assessment indicate above average habitat quality (score of 31 versus overall average of 22); notes on field sheet indicate "excellent habitat for SM bass and catfish/ carp.
