SPANISH LAKE, Mo.— The Missouri Department of Conservation (MDC) is helping to sponsor one of the largest litter clean-ups in the St. Louis area—the 10th Annual Confluence Trash Bash. The event is happening Saturday, March 24, from 9 a.m. until noon. MDC’s Columbia Bottom Conservation Area in Spanish Lake will serve as one of the starting locations for the event.

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 5,000 tires and more than 61 tons of trash and scrap from area streams and rivers.  Participants should report for sign up between 8 and 8:45 a.m. There will be free breakfast available for all volunteers before the cleanup begins.

Volunteers can choose from among the following starting locations:

  • Columbia Bottom Conservation Area, 801 Strodtman Road in Spanish Lake, 63138

Trash bags will be provided.  Transportation is available for school and other groups by contacting Colleen Scott ( ) at MDC.
