Volga River IA 01-VOL-296
confluence with Little Volga R. (S2 T92N R9W Fayette Co.) to confluence with unnamed tributary in SE 1/4 S24 T93N R10W Fayette Co.
Assessment Comments
1992 stream use assessment in Fayette County. 1995 biocriteria site (47C9).
Basis for Assessment
Used a review of the May 1992 DNR stream use assessment, and the September 1995 DNR biocriteria sampling in Fayette County to upgrade the assessment of support of the Class B(LR) aquatic life uses from FST to FS due to (1) presence of a very diverse fish community (26 species from 5 families (1995 biocriteria)) for streams in the Iowan Surface subecoregion, (2) presence of nearly all the expected fish taxa (11 of 12) for streams in this subregion, (3) presence of several sensitive species, including largescale stoneroller, Ozark minnow, rosyface shiner, northern hogsucker, black redhorse, smallmouth bass, rainbow darter, and banded darter, and (4) indications of above average habitat quality.
