Notes
During the 2014 assessment cycle this stream was placed on the impaired waters list for total phosphorus and degraded biological community. The upper portion of Black River is classified in Wisconsin Administrative Code as a Limited Aquatic Life (LAL). Based on NR102 the phosphorus criteria do not apply to LAL waters so this segment of the Black River is proposed for delisting during the 2020 cycle.Pollutant
