Assessment Comments

Two stream use assessments in 1991.

Basis for Assessment

Stream assessment forms indicate habitat in some reaches is degraded because of old, long reach channelization.   Habitat is better in other reaches where the stream meanders & flows over bedrock outcrops.   Fish community is relatively diverse in good habitat areas, less diverse in other reaches.   Good popul- ations of channel catfish observed at both assess.  locations.   DNR quaterly monitoring station was sampled 8 time between Oct.  91 and July 1993:  no violations of any Class B(WW) WQC.
