Operation Clean Stream

2017 marks 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 2016, over 1,632 citizen volunteers braved the wet weather to clean up nearly 500 miles of waterway in the Meramec River Watershed. Volunteers donated 4,900 hours and pulled 1,904 tires, 12,518 lbs of metal and 355.35 cubic yards of trash from the river. Check out our Facebook page for pictures of our awesome volunteers hard at work.

Volunteers are encouraged to bring their own boat and join a team on the river or walk the banks and clean up the parks and greenways in the Watershed.

“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
