2025 Highlights – Mission: Clean Stream’s 23th Anniversary!
In April 2025, all across the county, hundreds of volunteers helped restore many streams. Here in Wentzville, we spent our time in the Peruque and Dry Branch watersheds. These streams are important to the health of our community and support a variety of wildlife and land uses.
In two hours, 68 volunteers picked up over 1,100 lbs of trash!
Thank you to everyone who participated!
