Assessment Comments
Stream use assessment in Iowa County.
Basis for Assessment
[The segment IA 02-IOW-0110-0 was broken into two segments after the 1998 305(b) report. Assessment information prior to 1998 can be found in the documentation for segment IA 02-IOW-0010-2.]
Used the results of DNR stream use assessment to assess support of the Class B(LR) aquatic life uses as PS due to (1) indications on review form of "frequent" channel alterations (channel straightening), (2) only one fish species collected at assessment near Parnell and (3) habitat score (24) better than overall average score for DNR stream use assessments, but review form indicates extensive channel alterations.
