Milwaukee’s Waterways for Everyone
Community-led Advocacy, Education & Science
Meet Milwaukee Riverkeeper
Dedicated to a Swimmable, Fishable, Clean Milwaukee River Basin
Welcome to Milwaukee Riverkeeper! We’re a community-led non-profit using the power of science to protect our natural waterways by connecting with our local communities, pushing back against harmful policy, and empowering everyone who lives in our area to monitor and report water pollution. We are a member of the global Waterkeeper Alliance, and we seek to protect, improve, and advocate for better water quality, improved wildlife habitats, and safe land management in the areas in and around the Milwaukee, Menomonee, and Kinnickinnic Rivers.
We envision a future in which people from all walks of life can enjoy the healthy waterways of the Milwaukee River Basin.

Meet the Waterways We Protect
Improving Our Local Rivers, Lakes, and Estuaries
At Milwaukee Riverkeeper, we believe that clean, accessible water is a basic human right. When it comes to protecting our water, it’s about more than the rivers and lakes that we see. In fact, we work in three distinct water types including groundwater, drinking water, and surface water.
These water types are all interconnected. What we put in the ground affects the quality of our groundwater which affects the quality of our drinking water. What we put in our sewers and runoff from things like salt and factories ends up in our lakes and rivers, affecting our ability to enjoy surface water. This affects all water systems including those we protect:
