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

The Wisconsin River

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 hosted an informational webinar on February 21, 2018, which kicked off a series of informational meetings to outline its efforts to reduce phosphorus loads in waters throughout the basin. The same content will be presented at each meeting.

Upcoming meetings

  • March 5, 2018: 1-4 p.m., at the Quality Inn, Rhinelander (668 W Kemp St, Rhinelander, WI 54501)
  • March 6, 2018: 10 a.m. - noon and 4-6 p.m., at the Portage County Courthouse Annex Building (1462 Strongs Ave, Stevens Point, WI 54481-2947)
  • March 14, 2018: 10 a.m. - noon and 4-6 p.m., at the Portage Public Library (253 W Edgewater St, Portage, WI 53901)

Webinar

The Feb. 21, 2018, webinar provided an overview of the TMDL study and the supporting report.
