Assessment Comments
1992 SUA: habscr/fshscr=24/10 (seine). 1997 Biocriteria: Fish IBI= 43(fair), BM-IBI= 73(good).
Basis for Assessment
Used results of the August 1997 DNR biocriteria sampling approximately 2 mi NE of Tripoli to update the assessment of support of the Class B(LR) aquatic life uses developed for the 1994 report (=FST). Results of the biocriteria sampling were used to assess the support of the Class B(LR) uses as FST due to (1) presence of a moderately diverse fish community (14 species from 5 families) for streams in the Iowan Surface subecoregion, (2) presence of a majority (8 of 11) of the expected fish taxa for streams in this subecoregion, and (3) lack of violations of Class B(LR) WQ criteria in the sampled collected during biocriteria sampling.
