Assessment Comments

Previous assessments were based on 1995 DNR biocriteria sampling (habscr/fshscr = 29/11 (shock)).

Basis for Assessment

Used data from one biocriteria site in Winneshiek County to make use support determination.  Fish and habitat metrics from the stream use assessment protocol were applied to the data.  Data indicate very good physical habitat for small coldwater stream.  Fish community included many species indicative of good water quality and cold water (i.e., rainbow trout and mottled sculpin).
