The Class A1 use remains assessed as “not supported” due to levels of indicator bacteria (E. coli) that exceeded state water quality criteria. The Class BWW1 use remains assessed as “not supported” based on biological sampling data. The biological Class BWW1 use assessment indicated "full support" and was a monitored assessment because the FIBI samples used to complete the assessment were all collected in the last five years. However, until a monitored BMIBI assessment shows FS, this segment will remain in Category 5bt. Continuous dissolved oxygen monitoring data for the Class BWW1 use also shows full support. The Class HH use was assessed as “WINOFI” based on fish tissue sampling data.
