This TMDL addresses 10 bacteria impaired reaches and 12 nutrient impaired lakes in the Kettle River and Upper St. Croix River Watersheds. One TSS impaired reach, six macroinvertebrate IBI impaired reaches, and 10 fish IBI impaired reaches in the Kettle River and Upper St. Croix River Watersheds are not addressed in this TMDL and will be deferred because the water quality chemistry data was insufficient or because multiple stressors that cannot be quantified were identified. However, these reaches will be addressed through implementation of the Kettle River and Upper St. Croix River Watersheds Restoration and Protection Strategy (WRAPS) Report and local water planning efforts. Addressing multiple impairments in this TMDL is consistent with Minnesota's Water Quality Framework that seeks to develop watershed-wide protection and restoration strategies rather than focus on individual reach impairments.
