Assessment Comments

Assessment is based on results of the IDNR stream use assessment in October 1994, combined with DNR fishery survey in June 1989, both conducted in O'Brien county.

Basis for Assessment

Used results of the DNR stream use assessment in Oct.  1994, combined with DNR fishery survey in June 1989, to assess the B(LR) aquatic life uses as FST due to (1) habitat score (25) better than the overall habitat score (22) for DNR stream use assessments, (2) results of 1989 survey that showed 16 fish species from four families including channel catfish to 24" TL, and (3) comments on field sheet from Oct.  1994 assessment:  "very nice habitat, particularly at 40 cfs and even lower flows."
