Water Quality Assessment Reports to Congress

The Federal Clean Water Act requires that states report on the condition of surface water and groundwater in a biennial Water Quality Report to Congress. These reports provide a summary of water programs and resource condition on a statewide basis. For the 2010 reporting period, the WDNR is providing an integrated report which will combined the state's general assessment work with its impaired waters list updates.

The 2010 Integrated Water Quality Assessment Report, or Integrated Report, will use an updated Wisconsin Consolidated Assessment and Listing Methodology (CALM). To learn more about this process, review to the 2010 Integrated Reporting Pages. Previous reports are available in electronic or paper format: 2006, 2004, 2002, 2000, 1996, 1994, 1992, 1990, 1988, 1987 and earlier. DNR's earlier documents are available for review at the GEF II building, 101 S Webster St, Madison. Later versions are available electronically.
