Past Events

Operation Clean Stream

In 2017, we celebrated the 50th anniversary 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 2017, nearly 2,000 citizen volunteers came out to clean up nearly 500 miles of waterway in the Meramec River Watershed. Volunteers donated over 5,802 hours and pulled 2,029 tires, 16,272 lbs of metal and 539 cubic yards of trash from the river. Check out our Facebook page for pictures of our awesome volunteers hard at work and read our blog post to see the full Operation Clean Stream 2017 Report.

“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
