This spring, join together in a community-wide effort across Milwaukee, Ozaukee, Washington, and Waukesha counties to remove over 100,000 pounds of trash from our river system during the 29th Annual Milwaukee Riverkeeper Spring Cleanup!

Milwaukee Riverkeeper provides the gloves, trash bags, and FREE T-SHIRTS, you provide the people power, and together we will restore our waterways! 


Cleanup: Saturday, April 20, 2024, starting at 9am, arrival times vary

Following the cleanup, celebrate at RTG's 13th Annual Earth Day Celebration at the Harley-Davidson Museum



More than 90 locations 90+ sites in Ozaukee, Washington, Milwaukee & Waukesha Counties


We’re doing our best to make our rivers healthy, so it’s important for us to also care for the health of our communities at the same time.  Be sure to wear gloves and sunscreen!  Wash your hands and don’t forget to bring a reusable water bottle, cleaning up is hard work!
