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 2019! During cleanups on August 24 & 25, 1,478 volunteers removed 302 cubic yards of trash, 1,220 tires, and 11,095lbs of metal from the Meramec River Watershed! Please enjoy photos of the event on our Facebook page. Special thanks to our partners & sponsors! This event is sponsored in part by: Missouri American Water, Metropolitan St. Louis Sewer District, Bayer, Great Rivers Greenway, Radwell International, Enterprise Holdings,Meramec Valley Bank, USGS, Missouri Stream Teams and so many more!

In 2018, we celebrated the 51 years of 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.

In 2018, nearly 2,000 citizen volunteers came out to clean up nearly 500 miles of waterway in the Meramec River Watershed. Volunteers removed 286 cubic yards of trash, 1,375 tires, and 10,904lbs of metal of trash from the river. Check out our Facebook page for pictures of our awesome volunteers hard at work and read our blog post for photos and the Operation Clean Stream 2018 Summary 

“When an area is kept free of trash & other debris, visitors are more respectful & reluctant to add trash to the area.” 30 year veteran volunteer, Jerry Castillon
