North Cedar Creek IA 01-YEL-431

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

Water chemistry and biological monitoring data from the NPS monitoring project for 1996 and 1997 were reviewed.  During this period, no violations of wq standards were detected.  Monitoring of benthic macroinvertebrates and fish continue to indicate a healthy aquatic community.   Relatively low numbers of fish were found during 1995-1997 at North Cedar Creek and Sny Magill Creek monitoring sites.  No cause has been identified.  The types of benthic macroinvertebrates and fish found are indicative of relatively good water quality.  Annual habitat evaluations conducted since 1991 have documented good physical habitat conditions.  The B(CW) aquatic life use assessment was upgraded from FS/T to FS due to implementation of BMPs to reduce sediment and nutrient delivery from the watershed.
