Clackamas River Cleanup | Various Locations | September 8
The Down the River Clean Up is the largest and longest-running on-water cleanup event of its kind in Oregon, co-hosted by the Clackamas River Basin Council and We Love Clean Rivers. Over 3000 volunteers rally together in rafts, kayaks, and SCUBA gear, to scour the streambed and banks for trash, collecting an average of 1-3 tons each year, over half of which is recycled. Since 2003, over 44 total tons of garbage has been removed from the Clackamas River. The event includes a trash sweep of a 20+ mile stretch of the Clackamas River from Estacada to the confluence with the Willamette River in Oregon City.
