Cherry Creek Floodplain Restoration


Cherry Creek is the Snoqualmie River’s lowest major tributary; its location provides high recovery-benefit potential for chinook, coho, and other salmonids. The ditching and straightening of the lower mainstem has compromised salmon habitat in the Cherry/Snoqualmie floodplain, reducing the availability of off-channel high-flow refugia, juvenile rearing areas, and adult spawning grounds. Through its Salmon Recovery Board-funded feasibility study, Wild Fish Conservancy (WFC) prioritized actions to improve salmon habitat in Cherry Valley while meeting stakeholder drainage requirements. During the study WFC worked closely with King County Drainage District #7 (DD#7), WDFW, and NOAA Fisheries.

Goals & Objectives

To address compromised habitat conditions in lower Cherry Creek Valley, in 2012 Wild Fish Conservancy consolidated three floodplain ditches into a single naturalized stream channel. This project, located within the Mainstem-Primary Restoration Strategy Group, improved instream and riparian habitat diversity and complexity for nearly one mile of channel within lower Cherry Creek and its floodplain. These habitat improvements will benefit seven species of salmonids, including chinook and steelhead. This project complements Cherry Valley acquisition/restoration efforts being undertaken by WDFW and DD#7. WFC and project partners planted native vegetation within the new riparian corridor during winter/spring 2013 – additional plantings are planned for the coming years.
