Assessment Comments
Assessment based on results of a 1995 Biocriteria sampling and 1989/1992 IDNR stream use assessments conducted in Cherokee 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) due to (1) presence of a moderately diverse fish community for this subecoregion (12 spp., 5 fams in 1989 survey & 12 spp., 4 fams in the 1995 biocriteria sampling) and (2) presence of a majority of the fish taxa expected in stream of this subecoregion (6 of 9). Presence of the southern redbelly dace in the 1989 survey suggests above average water quality.
