16th Annual
South Platte River Cleanup 

Saturday, April 29th   Denver, CO

For the past 16 years, volunteers, partners, and friends have come together

for a day of river stewardship and celebration. This year is going to be even bigger!

Join us for a river cleanup followed by an after-party with free beer, food, and prize giveaways including a Kokopelli packraft, RMR river tubes, Meow Wolf tickets, and more. 

Our friends at Lavabox have created an awesome shirt design to commemorate our 16th year! 

RSVP and additional details are below. See you there!


We have several cleanup sites to choose from, and you can decide whether to paddle, wade or walk. Participants from all of the sites will meet at the after-party 

NOTE: The locations and start times for the on-water and on-land vary.

Sadly we have to cancel this year's event due to low flows. PLease join one of our on-land cleanups


This year we’re expanding our footprint and will have three on-land cleanup sites thanks to Orvis and two of their dealers. 


It takes less than three weeks for trash in the South Platte to reach the Gulf of Mexico.
