The Class BWW2 use was assessed as "partially supported" based on a fish kill investigation and on the results of biological sampling data. All other designated uses were "not assessed."
Presumptive Class A1 - No Data [Note: A TMDL for siltation, nutrients and low fish index scores in this segment was approved by EPA in 2005. Because the Section 303(d) impairments identified for the 2006 assessment/listing cycle are believed addressed by the TMDL, those impairments were placed into IR Category 4a.] Sources

is evaluated because it included samples not collected in the last five
years. Class
BWW2 – Fish kill Assessment: The Class
BWW2 aquatic life use assessment based on the 2018 fish kill placed this segment in Category
5b. The fish kill was caused by a “pollutant” or was suspected to be caused by
a “pollutant”; therefore, the Class BWW2 use was considered impaired. Because
the source of the pollutant was not identified and/or the enforcement actions
taken against the responsible party have not been resolved, the Class BWW2 use
was placed in Category 5b. Due to uncertainty regarding the recovery of the
aquatic life following the fish kill, any existing fish kill 5b impairment will
remain in Category 5b until more recent sampling has shown recovery of the
aquatic community or the responsible party has paid restitution.
