Join MCA to help raise funds and reduce litter in the Mill Creek Watershed at our reimagined 2026 Trash-A-Thon. Sign up for the month-long challenge and pledge to pick up litter from the location of your choice before it has a chance to get into the creek!

You can pick up your supplies and meet fellow watershed heroes at the launch party on September 3 (attendance not required for participation).

Throughout the month, take "trashy selfies" with your litter haul and submit them to our photo collection (photos@themillcreekalliance.org) for a chance at Trash-A-Thon fame. Prizes will be awarded at the Upper Mill Creek Cleanup on October 3.

No time to participate this fall? You can support the efforts of Mill Creek Trashletes by making a donation.
