Operation Clean Stream

Since 1967, The Open Space Council for the St. Louis Region has organized Operation Clean Stream, one of the country’s largest and longest running river restoration projects. The fourth weekend of every August, volunteers take to the Meramec River and its tributaries, working to undo damage caused throughout the year by flooding, careless littering and the unlawful dumping of debris. Volunteers participate both in canoes and boats, as well as on the shore, in nearby parks, and along nearby trails.

Thank you for a great Operation Clean Stream 2019! Please read our blog piece about the event and enjoy photos of the event on our Facebook page. Special thanks to our partners & sponsors! This event is sponsored in part by: Missouri American Water, Metropolitan St. Louis Sewer District, Bayer, Great Rivers Greenway, Radwell International, Enterprise Holdings,Meramec Valley Bank, USGS, Missouri Stream Teams and so many more!
