During the annual event, volunteers come together to help clean up the parks, neighborhoods, rivers, and creeks within the Missouri and Mississippi river watersheds. 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.
Confluence Trash Bash takes place in multiple sites throughout St. Louis City & County. More information about the sites is available on our website.
Volunteers can sign up for their chosen site on our website, with multiple sites to choose from all over the Lower Missouri and Mississippi River watersheds!
