Notes
This water was 303(d) listed in 1998 for Sediment/Total Suspended Solids. A sediment TMDL for this stream was approved in 2007. The 2014 cycle assessment noted elevated phosphorus and degraded biology. In the 2016 assessment elevated temperature was found. New water quality data reviewed in the 2024 cycle confirmed the degraded biology listing. Pollutant
