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. For the 40th anniversary of the event, volunteers will 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 trash. Volunteers can participate both in canoes and boats, as well as on the shore, in nearby parks, and along nearby trails.
