Maynes Creek IA 02-WFC-808
mouth (S7 T91N R17W Butler Co.) to confluence with unnamed tributary in S22 T91N R21W Franklin Co.
Assessment Comments
Assessment based on 2001 biocriteria data: Fish IBI= 53 (good), BM-IBI= 78 (excellent).
Basis for Assessment
Used a review of the field sheet from the July 1992 DNR stream use assessment in Franklin County, and results of the July 1995 DNR biocriteria sampling in Franklin County, to continue to assess support of the Class B(LR) aquatic life uses as FST due to (1) presence of relatively diverse fish communities (species/families, dstr->upstr: 21/5; 17/5) for streams in the Iowan Surface subecoregion (47c), (2) presence of nearly all of the expected fish taxa (10 of 11; 9 of 11) for streams in this subregion, and (3) indications on the July 1992 field sheet of relatively good habitat quality, with diverse substrates and presence of several pool/riffle sequences. Pasturing of the riparian corridor was identified as the primary impact to this stream.
