Assessment Comments
Assessment is based on results of an October 1994 IDNR stream use assessment conducted in O'Brien County.
Basis for Assessment
Continued to use the assessment of support of the Class B(LR) aquatic life uses developed for the 1996 report (=FST). A review of the field sheet from the October 1994 DNR stream use assessments shows (1) a moderately diverse fish community (11 species from 3 families) for stream in the NW Iowa Loess Prairies (47a) subecoregion and (2) presence of a majority of the expected fish taxa (7 of 9) for this subecoregion.
