The Annual Clark Fork River Cleanup
The Clark Fork River Cleanup is an annual tradition when the community comes together to clean trash along the riverbanks before spring runoff and high water carry thousands of pounds of urban trash and debris downstream. Hundreds of people–including individuals, families, friends, school groups, and businesses–gather to care for and protect our most precious resource: clean water.
Join us Saturday, April 18 from 9:00AM-11:00AM at Caras Park in Missoula, beginning with a cleanup of the Missoula river corridor (from Sha-Ron to Kelly Island) followed by a free brunch! Can’t volunteer this year? Click here to support the Clark Fork River Cleanup with a donation instead!
