Operation Clean Stream

Since 1967, The Open Space Council for the St. Louis Region has organized Operation Clean Stream, one of the country’s most significant and longest-running river restoration projects. 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.

Registration for Operation Clean Stream 2022 is OPEN! This is one of the largest river clean-up efforts in the country and we are excited to offer a new volunteer portal to make it easy for you to register, receive updates about your clean-up, and share your experience with us.

2021

In 2021 our #OperationCleanStream event took place from August 21st thru the 29th. The format of these clean-ups was a hybrid of both self-guided independent and group-led sites.

The Annual Operation Clean Stream group clean-ups and picnics took place on August 28th, 2021, at various locations throughout the Meramec Watershed. Over 2,000 volunteers participated as we celebrated 54 years of improving local rivers and open spaces! This year there were both group and self-guided clean-up options. Volunteers signed up to participate anytime between August 21st and 29th or in group clean-ups on August 28th. In addition, Our Passport 2 Clean Water Event also took place in a socially distanced format with safety in mind. Read more about last year’s Passport 2 Clean Water Event on our Blog.

Over the last couple of years, we have seen how important open spaces and clean water are to our communities’ health and well-being. So we thank you for helping to keep them beautiful and clean! Click here for this year’s Operation Clean Stream Program Report.
