Assessment Comments
1995 Biocriteria: Fish IBI=36 (fair), BM-IBI=79 (good).
Basis for Assessment
Used data from one biocriteria site in Clay County to make use support determination. Fish and habitat metrics from the stream use assessment protocol were applied to the data. Results indicate fairly poor habitat quality due to excessive sediment, widening of channel, and removal of natural riparian vegetation. Fish community was dominated by relatively pollution-tolerant cyprinids and other fish. Fairly low number of fish sampled. Water was moderately turbid.
