confluence with unnamed tributary (aka Trout Run) in S27 T98N R8W Winneshiek Co.) to confluence with unnamed tributary (aka Trout Cr.) in S33 T98N R8W Winneshiek Co.
Assessment Comments
Stream use assessment in Winneshiek County, special stream assessment in Spring 1995.
Basis for Assessment
Used a reivew of the field sheet from the May 1992 DNR stream use assessment and the results of the May 1995 DNR/UHL stream survey to continue to assess support of the Class B(LR) aquatic life uses as "partially supported" due to indications of severe stream bank erosion and sediment overload in the stream channel. This stream reach has been recently monitored, and nonpoint management practices have been implemented in the watershed, as part of CWA Section 319 water quality project. The goals of the project include reduction of the amount of sediment, nutrients, animal manure, and pesiticides entering water supplies by helping watershed landowners and farmers implement soil conservation and water quality practices. Some water quality improvement has been noted. For more information on the Trout Run Water Protection Project, call 319/382-4352.
