Rock River TMDL

Snowy Owl in Flight Horicon Marsh

Rock River Recovery is the official name of the Rock River Basin TMDL implementation process. To read more detail about the Rock River Recovery, explore Rock River Recovery details.

The EPA's Impaired Waters Restoration Pipeline [exit DNR] is portrayed in the figure below and describes the overall process of listing to recovery. The Rock River Recovery project covers total suspended solids and total phosphorus. While other pollutants are found in the basin, this TMDL is focused on these two pollultants.
