Assessment Comments

Assessment is based on results of water quality and biological monitoring conducted as part of the Sny Magill / Blood Run project.

Basis for Assessment

Used data from one biocriteria site in Clayton County to make use support determination.  Fish and habitat metrics from stream use assessment protocol were applied to the data.  Data indicate very good physical habitat quality and fish collection included juv.  and adult brown trout and juvenile brook trout.  Water quality data suggest that episodes of low DO occur in this stream and other streams in the Sny Magill and Bloody Run watersheds.   The aquatic communities of these watersheds, however, appear healthy and do not suggest a WQ impact due to low DO/organic enrichment.   Cause of low DO may be related to runoff events, but issue needs further study.
