Big Sioux River Greenway Cleanup

Join the City of Sioux Falls on Saturday, October 10 from 9 a.m. to noon for the Big Sioux River Greenway Cleanup! The Cleanup will take place at 9 different locations along the Bike Trail surrounding the Big Sioux River. 

Volunteer coordinators will be at each park location with bags, maps, and gloves. All we need is you! Volunteers can stay for as little or as long as they’d like. In 2017 over 6,500 pounds of trash was removed from the banks of our river.
