Columbia Slough Watershed Council


To protect and enhance the Columbia Slough and its watershed through community engagement, education and restoration.

Bottom Line for Portland

Last year, CSWC provided 30 habitat restoration work parties; 323 programs to 6,900 students; and large, 500+ person events such as Explorando el Columbia Slough in predominantly low-income and communities of color in North Portland through Fairview and Gresham.

“I found the experience with you and your group on Saturday to be just excellent. It was both educational and fun! Well put together, safe, interesting, satisfying! Please pass my compliments on to your crew! —Bike the Levees event participant

How far does a $10 donation go with your organization?

$10 buys a seat on a canoe for two students’ first time on the water, plants a native tree to provide shade and habitat, or covers our staff's transportation cost to attend three community meetings in support of environmental justice work.

How far does a $50 donation go with your organization?

$50 can purchase two new life jackets, a bus for Reynolds School District students to come to Whitaker Ponds to learn about macroinvertebrates, or two shovels for volunteers to plant trees.
