Watershed Restoration Viewer

The DNR's Watershed Restoration Viewer is an interactive web mapping tool for exploring water quality improvement projects across Wisconsin. When waters are listed as "impaired" as defined by the EPA, the DNR works to improve the waters by implementing various types of frameworks such as Total Maximum Daily Loads (TMDLs) and Nine Key Element Plans. If the waters are already "healthy," the DNR works to maintain their healthy status for current and future generations to enjoy.

Watershed Restoration Viewer

Key Features

This viewer allows users to search and map DNR information regarding water quality by focusing on places in Wisconsin where the DNR is working with partners to provide improved water quality. Users can view current water restoration plans along with impaired waterbodies in order to gather a quick assessment of how the state is working toward improving and maintaining water quality. Described below is a more specific look at what is included in the viewer.

All active Nine Key Element plans

Nine Key Element plans are located on the Watershed Restoration Plans theme and include clickable polygons to access a quick overview of each plan number along with a brief description. Viewable plans in this theme are all considered "active" and do not include expiring plans or those in development.

All TMDL plans

TMDL plans include specific subbasin-based report data for the Upper Fox/Wolf, Lower Fox, Rock River, Wisconsin River, Milwaukee River and Northeast Lakeshore. Subbasins are clickable and will generate a quick summary of TMDL values for specific parameters (providing an easier way to retrieve TMDL information than sifting through static reports). TMDL information associated with individual permits are also available within each TMDL theme. (NOTE: Values reflect individual permits as stated in the TMDL at the time of approval. Actual permit limits may vary.)


This tool provides pollutant, water resource and landscape characteristics for any Wisconsin watershed. A PRESTO-Lite page is available for more information and a description of how the tool works.
