Assessment Comments
Assessment is based on results from September 1990 IDNR stream use assessment conducted in Sioux county.
Basis for Assessment
Upgraded the assessment of support of the Class B(LR) aquatic life uses from PS to FST due to a review of the field sheet from the September 1990 DNR stream use assessment which shows that the fish community of 9 species and 3 families contains nearly all species/genera expected for a Class B(LR) stream in this region. Thus, the composition of the fish community strongly suggests that the Class B(LR) uses are fully supported. The field sheet does not indicate threats to the continued support of these uses other than isolated areas of channel alterations and streambank erosion. The data used to develop this assessment are more than 5 years old; thus, the 305(b) assessment category = "evaluated." Addtional monitoring is needed to determine the status of the aquatic communities and habitats. The data upon which this assessment is based are more than 5 years old; thus, the 305(b) assessment category = "evaluated."
