Assessment Comments
Stream use assessment in Clinton County.
Basis for Assessment
Used different criteria to evaluate stream use assessment data: habitat score > 22 and fish score > 10 (with seine) = FST; i.e., these values exceed the median scores for stream use assessments made between 1990 and 1992. In addition, I conducted fish survey in lower (B(WW)) reach in late 1980s and was impressed by predominance of coarse substrates and exceptionally diverse fish community (19 spp.).
