Wisconsin’s 2012 Impaired Waters List
Every two years, Section 303(d) of the Clean Water Act requires states to publish a list of all waters that are not meeting water quality standards.
The existing Impaired Waters List includes more than 700 rivers, streams and lakes. In the draft 2012 list, updates include 147 new waters to the list. The primary pollutants are total phosphorus, mercury and total suspended solids. Twenty-eight waters are being proposed for delisting including three streams that have been successfully restored: German Valley Branch in Dane County and Eagle and Joos Valley Creeks in Buffalo County.
Public comment period reopened from May 30 – June 30
