Save The Date! - River des Peres Trash Bash
When: Saturday October 25, 2025
Where: Multiple Locations in the River des Peres Watershed
Save the fourth weekend in October for the River des Peres Trash Bash, October 25th.
Volunteers choose from multiple clean-up locations or storm drain marking sites each year. All clean-up opportunities have a site supervisor present to provide volunteers with supplies, sign-in participants and lead them through the clean-up of the chosen site. Do you know of a stream site in the River des Peres watershed that needs a group of volunteers to clean of litter or have a stream team litter pickup project that needs support? Open Space would love to hear from you! Please contact This email address is being protected from spambots. You need JavaScript enabled to view it. to provide the information for the site that needs help.
River des Peres Watershed Festival is October 25th! (Following the cleanup)
If you thought Bike with Your Boots On was fun (and it is!) - the annual Trash Bash & Watershed Festival is a once a year good time for all.
Join us for the RdP Watershed Festival with Passport to Clean Water 11 am - 2 pm following the cleanups. this event is a volunteer appreciation picnic with live music, unique trash contest and educational activities. (Truly something for everybody!)
