Assessment Comments

Two stream use assessments in July 1991.

Basis for Assessment

Stream assessment forms indicate below average habitat quality.   Little diversity of habitat and substrate observed.  Stream is generally very shallow in some reaches.   Long reaches of old channelization common.   Tree riparian vegetation common.  Scour pockets and woody debris provide some diversity of habitat.  Fairly diverse fish community observed; however, community is not very balanced and most species have low population numbers.
