Second Phase of Chinook Bend Habitat Restoration Project Completed
September Newsletter - Snoqualmie Watershed Forum

This summer, King County removed approximately 1,500 feet of a degraded levee and revetment at the upstream end of the Chinook Bend Natural Area. The project was implemented to allow the river better access to its floodplain in an effort to increase and improve habitat for salmon and trout. The project involved the installation of a temporary portable dam to divert flow away from the bank and the removal of several hundred truckloads of large rocks. This was the second component of a three-phased approach to the floodplain restoration project. The first phase was implemented in December 2008 when 150 large cottonwood trunks, also known as boles, were installed to mimic floodplain roughness and to protect more than 8,000 trees and shrubs planted by volunteers over the past ten years.

The last phase of the habitat project will be implemented in the summer of 2010 with the removal of the downstream revetment and the installation of a setback revetment to protect Carnation Farm Road. The site will also see the addition of public amenities including an ADA trail, interpretive signage, a viewing platform, a public parking lot and a restroom.
