West Fork Little Sioux River IA 06-LSR-1598
mouth (S12 T84N R45W Monona Co.) to confluence with a small unnamed tributary near Climbing Hill in S16 T87N R45W Woodbury Co.
Assessment Comments
Assessment is based on results of three October 1995 IDNR stream use assessments conducted in Monona and Woodbury counties.
Basis for Assessment
Upgraded the assessment of support of the Class B(LR) aquatic life uses from PS to FST due to a review of the field sheets from the October 1995 DNR stream use assessments that show a fish community that contains all of the expected species/genera* in Class B(LR) streams of this region. Thus, despite the threats to support of these uses from extensive channelization and frequent stream bank erosion, this stream supports a fish community that suggests that the Class B(LR) uses are fully supported. * Number of species/families at the Hornick, Holly Springs, and Climbing Hill assessment sites: 5/2; 8/3; 5/3.
