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, event 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 trash. 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 2018! During cleanups on August 25 & 26, 1,667 volunteers removed 286 cubic yards of trash, 1,375 tires, and 10,904lbs of metal from the Meramec River Watershed! Please enjoy photos of the event on our Facebook page.
