Assessment Comments
Assessment based on 1995 biocriteria data.
Basis for Assessment
Used data from one biocriteria sampling site to make use support determination. Fish and habitat metrics from stream use assessment protocol were applied to the data. Habitat alteration caused by off-site flow (channelization) impacts and sediment deposition appear to be main causes of use impairment. Despite habitat degradation, the stream supports a fairly abundant and diverse fish community. Borderline assessment call between PS and FST.
