Protecting and restoring the Clark Fork watershed since 1985

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 19 from 9:00AM-11:30AM at Caras Park in Missoula, beginning with a cleanup of the Missoula river corridor (from Sha-Ron to Kelly Island) followed by a free lunch! Can’t volunteer this year? Click here to support the Clark Fork River Cleanup with a donation instead!

Sponsor the Clark Fork River Cleanup

Sponsoring the Clark Fork River Cleanup is a meaningful investment that showcases your commitment to the health and wellbeing of both the river and our communities. Sponsorship packages are detailed below and include benefits like dedicated acknowledgements and special sponsor spotlights in printed materials, social media posts, e-newsletters, and radio ads; speaking and tabling opportunities; and more—each an opportunity to highlight your business as a proud supporter of one of Western Montana’s most impactful environmental events. 

With the Clark Fork River and its tributaries facing the dire consequences of millions of stalled pre-approved federal dollars, the stakes have never been higher and support from local businesses never more crucial.   

We truly hope to partner with you on this year’s Cleanup—for a more vibrant, beautiful downtown and a clean, thriving Clark Fork River.
