Impaired Water Notes
Best professional judgment from observations during TMDL monitoring and fish surveys conducted in 2005. Sedimentation is an issue throughout the length of the stream, as deposition is extensive in runs and pools. Row cropping and pasturing have been observed adjacent to stream banks in the stream corridor of the lower 5.32 miles. The currently listed impaired segment (miles 5.32-9.94) is influenced by low flow and intermittent pools, in addition to non point source pollution from nearby agricultural practices.
