Operation Clean Stream and Passport to Clean Water

August 24th 8:00 am - 1:00 pm

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. This event would not be possible without volunteers!

The Open Space Council invites you to help this year on Saturday, August 24. You can choose one of several cleanup locations along the Meramec River. After the cleanup, bring the whole family to Passport to Clean Water in Greentree Park.

This program is for children, ages 5 to 18 years, and their families. You can walk a local greenway, enjoy nature, and learn about natural resources.  At the beginning of the event, each child receives a passport that will be stamped after a visit to each booth and they can redeem it at the final booth for a prize. This program is great for Girl Scout and Boy Scout troops, youth groups, school groups and more!
