Welcome
 
 

The Chehalis watershed is the largest in Washington state contained completely within the state’s boundaries. Its multiple headwaters include streams in the Willipa hills, the Cascades in east Lewis County, the Black Hills, and the Olympics. The waters of the watershed finally reach the Pacific Ocean via the Chehalis River and Grays Harbor. The watershed includes parts of Lewis, Thurston, Grays Harbor, and Mason counties and tiny slivers of Pacific and Wahkiacum counties.

Enter and learn what we are doing and what you can do to protect our natural resources in the Chehalis Basin.
