Assessment Comments

Assessment is based on results of 1995 Biocriteria sampling.

Basis for Assessment

Used data from one biocriteria sampling site to make determination of use support status.   Fish and habitat metrics from the stream use assessment protocol were applied to the data to make the determination.   Numbers of fish observed was fairly low, but diversity was reasonably good.   Habitat was fairly-good for a low gradient stream in northcentral Iowa.   Two Iowa Darter specimens were included in fish collection.   Many juvenile north.  pike also observed.   Results of the three DNR stream use assessments conducted in this segment also suggest that the Class B(LR) aquatic life uses are FST due to (1) habitat scores for 2 of 3 sites of 24 which is better than the overall median score (22) for DNR stream use assessments, (2) only moderately diverse fish communities (10 species) but low percentage of pollution tolerant species (30% and 40%).
