Confluence Trash Bash

Confluence Trash Bash is one of the largest stream clean-up events in the state.

Confluence Trash Bash is the annual clean-up in North St. Louis and St. Louis County. All are welcome, no experience required! Individual volunteers, civic groups and youth organizations are encouraged to attend.

Volunteers can choose from multiple locations as their starting site, after which they will be assigned to specific areas to clean.


Dress appropriately for working outside. Be prepared to get wet and muddy. 

Bring a water bottle.
