Stream use assessment.
Basis for Assessment
Used results of the October 1992 DNR stream use assessment in Kossuth County to assess support of the Class B(LR) aquatic life uses as FST due to (1) habitat score (24) better than the overall median score (22) for DNR stream use assessments, (2) indications on field sheet of diverse substrates, relatively stable stream banks, riparian zone dominated by trees, and presence of a few pool/riffle sequences. Field sheet notes frequent channel alterations (straightening) but states that this is "old ditching" thus suggesting that the stream may have recovered from the most recent channelization. Field sheet inidates that water was too deep to effectively seine.
