 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!

River Clean Up 2021 - Saturday, August 14th

How to Sign Up: Use the map to decide which stretch you would like to clean.

Click on the sign up link under each specific site.

Pick up supplies: Gloves and trash bags will be available for pickup at all Valley Fly shops and the BRWF office at

178 South 2nd Street in Hamilton. 

Available two weeks leading up to event.  Feel free you use your own trash bags if you'd prefer.

Trash Drop Off: 5:00-8:00 PM at Hamilton's Kiwanis River Park. Celebrate all of the work done for the Bitterroot River as you drive through and drop off the trash collected.

Community Celebration: 5:00-8:00 PM Swing by the festivities in River Park, where there will be live music from Pinegrass, and local food trucks! Prizes will be awarded at 7:30 PM.

Use this map to check out the different floating and walking sections, click the site you'd like and then use the sign-up link under each site name to claim your favorite spot!                                                 

You are responsible for your own transportation to walking sites, as well as your own transportation and boat for floating sections. If your favorite float or walking site is not listed, please let us know and we will add it!  Claimed sites will be grey.

Have you seen any larger trash that you think might need extra work/coordination to get out?  Let us know what the item is (or appears to be), it’s location (gps coordinates would be best), and if there are specific tools that you think someone would need to get it out and we'll work on it.

Printable scavenger hunt for kids! Fill one of these out and return it to the trash drop off at Kiwanis River Park for a prize!

This guide shows you some of the noxious weeds we want to help remove from our valley. Take a look, print a copy, or learn more from the Weed District. Don't forget to bring gloves if you plan to pull weeds!
