Assessment Summary
The Class A1 use was assessed as "not supported" due to levels of indicator bacteria (E. coli) that exceeded state water quality criteria. The Class BWW1 use was assessed as “fully supported” based on water quality monitoring data and biological sampling data. The Class HH use was assessed as “fully supported” based on fish tissue sampling data.
