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.

Thanks to all who volunteered for Operation Clean Stream 2020!

During the past few months, we have seen how important parks, open spaces and the natural environment is to our communities’ health and well-being. Thank you for being a part of this year’s Operation Clean Stream event! We thank you for helping to keep them beautiful and clean! Your work helped remove trash, tires and flood debris from the Meramec Watershed. In total, 528 volunteers reported participating in the event over the course of 9 days in August. Volunteers removed 142 cubic yards of trash, 1,735 tires, and 2,982 lbs of metal from the Meramec River Watershed this year.
