SPANISH LAKE, Mo.— The Missouri Department of Conservation (MDC) is once again helping to sponsor one of the largest litter clean-ups in the St. Louis area—the 11th Annual Confluence Trash Bash.

Volunteers will help clean up rivers and creeks that lie within the Confluence Greenway. Past cleanup efforts have drawn over a thousand volunteers who have removed 6,700 tires and more than 150 tons of trash and scrap from area streams and rivers. Participants should report for sign up between 8 and 8:45 a.m.
