Access limited during restoration work at King County’s Chinook Bend Natural Area


While visitors will still be welcomed to King County's Chinook Bend Natural Area, a habitat improvement project in a portion of the 59-acre natural area will require some access restrictions.


A summertime project to improve habitat conditions for fish andChinook_Bend_pond wildlife along the Snoqualmie River, while maintaining flood protection for nearby landowners, will require temporary public access restrictions at King County Parks’ Chinook Bend Natural Area.

To ensure public safety, the County’s 59-acre natural area, roughly two miles north of Carnation, will have partial access restrictions during construction, which is likely to begin July 6 and expected to be completed by July 17. The upstream end of the site will be entirely closed to public access during construction.

Temporary traffic delays along with increased noise and truck traffic along Northeast Carnation Farm Road are expected during construction, and flaggers will be on-site to direct traffic as needed. The parking lot on the north end of the site will remain open, as will trails near the parking lot and in the downstream end of the Natural Area. Trail users should be aware that trucks could be present along the access road. 

Work this summer includes removing approximately 100 feet of a revetment at the upstream end of Chinook Bend and removing a small culvert. The in-water work must be done during the summertime low-flow season on the Snoqualmie River before the fall rains and adult salmon return to spawn.

This is the final phase of the Chinook Bend Floodplain Enhancement Project. The previous phases were implemented in 2009 and 2011 and included removing more than 2,000 feet of the levee and revetment throughout the site.

Chinook Bend is bordered on three sides by the Snoqualmie River, which features the largest population of federally protected chinook salmon in King County.

The public amenities at Chinook Bend, including a trail that is wheelchair accessible, interpretive signage, public art, a public parking lot and a restroom will all remain accessible during construction. 

The Chinook Bend Natural Area was donated to King County by Nestle USA in 2000. The floodplain has been undergoing reforestation for the past 12 years, and roughly 15,000 native trees and shrubs have been planted by volunteers within the project area to restore the floodplain to a forested condition.

The Chinook Bend Habitat Restoration Project is funded by the King Conservation District, Salmon Recovery Funding Board and the King County Department of Natural Resources and Parks. Amenities are funded by a grant from the state Aquatic Lands Enhancement Account program.
