The Mountains to Sound Greenway Trust is currently undertaking its biggest restoration project yet, and one of the largest in Lake Sammamish State Park’s history! After nearly a decade of planning, we’re working with the Washington State Parks & Recreation Commission (State Parks) and other partners to restore Issaquah Creek and improve important salmon habitat during summer 2025.
The Mountains to Sound Greenway Trust and Washington State Parks have worked together for more than 15 years to improve salmon habitat within Lake Sammamish State Park. You’ll see the results of these restoration efforts during a 1.5-mile walk along Issaquah Creek, and learn why native trees and vegetation are so critical to improving water quality and wildlife habitat. You will also see heavy equipment that will be placing large woody material in the stream, widening the creek and reconnecting the floodplain.
Where: Lake Sammamish State Park, Issaquah
Host: Mountains to Sound Greenway Trust
