Missouri River Relief is headed to the Confluence of two great rivers to host a cleanup at Columbia Bottom Conservation Area! The confluence, where the Missouri and Mississippi Rivers meet, lies north of the heart of St. Louis. We haven’t been back since 2018, 4 years! Boy does time fly. MRR is excited to clean up St. Louis’s reach of the Missouri River! Please join us on September 17th for a day of stewardship, fun and exploration.
