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. 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.
