Operation Clean Stream

Since 1967, Open Space STL has organized Operation Clean Stream, one of the country’s most significant and longest-running river restoration projects. Join us August 24, 2024, for the 57th year of Operation Clean Stream.


About OCS:

Every August, volunteers take to the Meramec River and its tributaries, working to undo the damage caused throughout the year by flooding, careless littering, and the unlawful dumping of debris. Volunteers participate in canoes and boats, on the shore, in nearby parks, and along trails. Volunteers sign up online pre-event to secure their spot and free OCS collectable t-shirt. Registration opens mid to late June on our volunteer platform!
