The Class BWW2 use was assessed as "not supported" based on biological sampling data. All other designated uses were "not assessed." 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.

Class BWW2 – Fish kill Assessment:
The Class BWW2 aquatic life use assessment based on the 2018 fish kill
initially placed this segment in Category 4d. 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. However, because restitution for the
fish killed was received, the Class BWW2 use was placed in Category 4d
(impaired but TMDL not required). DNR feels that (1) TMDLs should not be
required for a fish kill caused by a one-time illegal or unauthorized release
of a pollutant where enforcement action was taken and (2) enforcement action is
more appropriate and effective for addressing a spill-related impairment than
the TMDL process. Based in DNR IR methodology, the fish kill is now greater
than five years old (2023); therefore, this BWW2 fish kill assessment was moved
from Category 4d to Category 3b.
