Operation Clean Stream is August 24th!

Join us on Saturday, August 24th for Operation Clean Stream, proudly celebrating 52 years of river stewardship in 2019! The event will take place at various locations throughout the Meramec River Watershed. We hope you will volunteer with us to improve local rivers and open spaces!

We are especially in need of paddlers to get out on the water at this year’s Operation Clean Stream and bring their own canoes/kayaks. If you have a watercraft you would like to volunteer, please contact us via email at info@openspacestl.org.
