from town of McIntyre (S34 T100N R15W Mitchell Co.) to north line of S20 T100N R15W Mitchell Co.
Assessment Comments
Assessment is based on results of 1996 IDNR/UHL biocriteria sampling (15 spp., 5 fams.).
Basis for Assessment
Used results of the 1996 biocriteria sampling 4 mi NW of McIntyre to assess support of the Class B(CW) aquatic life uses as FST. Although results of this sampling showed a moderately diverse fish community of 15 species from 5 families, and although a majority of the expected fish taxa were present (8 of 11), no coldwater species (e.g., trout or sculpins) were captured. Additional monitoring is needed to determine whether this reach is appropriately designated for Class B(CW) aquatic life uses. The level of dissovled oxygen (5.3 mg/l) in the sample collected during biocriteria sampling was less than the 7.0 mg/l Class B(CW) WQ criterion.
