Each year, volunteers for Bitter Root Water Forum pull thousands of pounds of trash out of the Bitterroot River. Volunteers are assigned stretches of the river from Sula and Painted Rocks to the confluence at the Clark Fork in Missoula. Be a part of this year’s annual River Clean Up and help keep our beautiful Bitterroot River clean and flowing!
