Watershed Restoration Viewer

The Watershed Restoration Viewer is a DNR interactive web mapping tool for exploring water quality improvement projects across Wisconsin. When waters are listed as impaired, the DNR works to improve them through various types of federally supported frameworks such as Total Maximum Daily Loads (TMDLs). When the waters are already exceptional, the DNR protects them for future generations to enjoy.


This tool allows users to search and map DNR information regarding water quality with a focus on the places in Wisconsin where the DNR is working with partners to provide exceptional water quality. Within these areas, website visitors can explore water quality standards, the current condition of rivers and lakes, and the results of models that the DNR uses to allocate the least amount of resources for the greatest overall improvement in water quality.


The map viewer is organized by “themes”. Select a theme to view information about the included layers.
