Assessment is based on results of three October 1995 IDNR stream use assessments conducted in Monona and Woodbury counties.
Basis for Assessment
Used results of three October 1995 stream use assessments in Monona and Woodbury counties to assess the support of the Class B(LR) aquatic life uses as PS due to (1) habitat scores (20, 21, and 23) generally poorer than the overall median habitat score (22) for DNR stream use assessments despite relatively favorable low-flow characteristics, (2) field sheets indicate lack of habitat diversity and extensive channel alterations, (3) fish scores (11, 10, 12) generally poorer than the 75th percentile score for stream assessments made with electrofishing (although assessments were made during high flows which hindered collection effeciency). Habitat somewhat improves near the Climbing Hill site due to meandering.
