Opportunity Details

River and Land Cleanup with Willamette Riverkeeper

Join SOLVE and Willamette Riverkeeper for a cleanup of the Willamette River’s Holgate Channel!

Located just south of the downtown Portland core, the ecologically-important Holgate Channel connects the 160-acre Oaks Bottom Wildlife Refuge and the Ross Island archipelago, providing habitat for native fish and wildlife species like the threatened Chinook Salmon, as well as other species that rely on the area for nesting, including bald eagles and great blue herons.

Spend the day outside and improve the environmental quality of the Holgate Channel! If you are an experienced boater, paddleboarder or kayaker we encourage you to BYOV (bring your own vessel). If you are on foot, we will be picking up trash along the riverbank at Sellwood Riverfront Park.

To register for the event, please go to the Willamette Riverkeeper's website here.

When: Thursday, October 6, 9:00 AM to 11:00 AM. 

Advanced Registration Required: Pre-registration is required! Please sign up on the Willamette Riverkeeper website here.

Meeting Location: Volunteers will be meeting at Sellwood Riverfront Park. MAP LINK
