It’s nearly Bashin’ Trash season!
If you enjoy the Missouri and Sun Rivers and all the benefits these amazing resources provides, this is your chance to give back! Join this annual event to clean up over 140 miles of the Missouri and Sun Rivers. We need volunteers to help on the water (if you have your own boat) and on land. Sign up today to clean up your favorite reach, park, or trail!
For 2026, we are changing the format of this event to span spring and summer. Pick your date, gather your friends, family, or coworkers, and pick up your Bashin’ Trash Cleanup Kit from the Sun River Watershed Group or High Plains Conservation District. CLICK HERE to request more information.
Each group will get supplies needed to do a cleanup including BINGO sheets for everyone. You can pick your park or river area to cleanup or we can suggest an area for you. Send us your group photos and BINGO sheets to be entered for prizes, which will be awarded at the end of the season.
On the interactive map below, yellow icons indicate river sections or parks that have not been adopted yet. There are many parks, trails, or river sections not shown - just let us know where you want to clean and we’ll add it to the map. Icons in blue indicate sections or parks that have been adopted - you can still clean up in these areas. Just contact the captain for that section (below). Scroll down to sign up to help with an existing section or to adopt your own.
Registration to volunteer for this event is prefered so we can have a headcount for each section. We’re working on prizes and other fun features for this event. If you want to receive updates, make sure you sign up today! If you have a team, please have each member sign up individually.
