Assessment Comments
Two stream use assessments in 1990.
Basis for Assessment
Stream assessment forms indicate below average habitat quality. Poor low flow habitat characteristics noted. Rel. low diversity of substr. observed and frequent bank erosion suggest susceptability to high flows. Frequent channeliz. noted near mouth. Fair diversity of fish observed, dominated by cyprinid species. Stream lacks good pool habitat in this segment.
