Wisconsin River Total Maximum Daily Load (TMDL) A framework for water quality improvement

The DNR, together with many partners throughout the basin, are working to improve water quality of the Wisconsin River, its reservoirs and tributaries. The Total Maximum Daily Load (TMDL) study and implementation plan will provide a strategic framework and prioritize resources for water quality improvement in the Wisconsin River Basin.

The Wisconsin River TMDL study area spans Wisconsin's central corridor from the headwaters in Vilas County to Lake Wisconsin in Columbia County, covering 9,156 square miles, approximately 15 percent of the state.

2018 public input opportunities

The DNR will host an informational webinar for the public in February and a series of informational meetings in March to outline its efforts to reduce phosphorus loads in waters throughout the basin.

The DNR will conduct a webinar on February 21, 2018, at 1 p.m. to provide an overview of the TMDL study and the supporting report. There is no requirement to pre-register for the webinar. The webinar will be recorded and made available on this website.

The webinar kicks off a series of informational meetings. The same content will be presented at each meeting.

  • March 5, 2018, 1-4 p.m., at the Quality Inn, Rhinelander (668 W Kemp St, Rhinelander, WI 54501)
