Stakeholder Engagement​​

Stakeholders from across Wisconsin have been engaged by the Interagency Water Quality Workgroup via a series of informational webinars, listening sessions, and one-on-one interviews to ensure the new NLRS is relevant to and aligns with the efforts of the many organizations and individuals working to address nutrient pollution. This process has been designed to allow stakeholders the opportunity to participate in the initial phases of strategic planning and also represents a starting point for ongoing collaboration across sectors to identify practical, science-based solutions and priority actions that protect water quality while being supportive of agriculture. 

Individuals and organizations that have participated in the stakeholder engagement process will be invited to participate in a December 2025 roundtable, a working meeting that brings together a diverse group of stakeholders (farmers, conservation and environmental groups, industry, and government) face-to-face, in one place, at one time, to ‘roll up their sleeves’ and participate directly in creating a unified strategy for reducing nutrient loss from agricultural land in Wisconsin.

Benefits of​ a Statewide Nutrient Loss Reduction Strategy

Progress on addressing excess nitrogen and phosphorus in surface and groundwater requires an ‘all hands on deck’ approach to address both point sources (e.g., wastewater treatment facilities) and nonpoint sources (runoff from rural and urban landscapes). There are many organizations and individuals all over Wisconsin working hard to identify and implement programs and practices that will reduce nutrient pollution. Wisconsin is part of two major basins: the Mississippi River Basin, which ultimately influences Gulf hypoxia, and the Great Lakes Basin, so nutrient loss here has broad implications.​ A statewide nutrient loss reduction strategy provides an opportunity for all key stakeholders in both the public and private sector to identify effective, practical approaches to reducing nutrient loss and then work together, rather than in isolation, to achieve those shared goals.

In​teragency Water Quality Workgroup

The Wisconsin Department of Natural Resources (DNR) is leading the development of a new stat​ewide Nutrient Loss Reduction Strategy (NLRS) in collaboration with the Interagency Water Quality Workgroup comprised of representatives from the Wisconsin Department of Agriculture, Trade and Consumer Protection (DATCP); Wisconsin Land and Water Conservation Association; the Natural Resources Conservation Service (NRCS); University of Wisconsin – Madison, Division of Extension; Dane County Land and Water Resources Department; and the US Geological Survey (USGS).
