Description    


Hansen Creek is a major tributary of the middle Skagit River in northern Puget Sound, Washington. It has documented spawning and rearing habitat for Puget Sound Chinook Salmon and Steelhead and is a Tier 2 Target Area in the Skagit Watershed Council Strategic Approach. This proposed restoration project will be the second major, reach-scale floodplain initiative in the low gradient areas of the lower tributary.
The goals of the Hansen Creek Reach 5 Floodplain Restoration Project include: 1) Removing/altering levee segments to reconfigure the location of Hansen Creek from its current straighten and degraded location to more suitable location to the east of its current location, thus adding 4.9 acres of habitat. 2) Restoring floodplain connectivity of Hansen Creek and the adjacent wetlands including berm alteration to restore hydraulic and physical habitat continuity and complexity, 3) At Hansen Ceek new channel with native riparian to provide shade, long-term LWD recruitment and in-channel complexity, while removing invasive species. 4) Increasing instream habitat in Reach 5 from approximately 155,200 to 208,000 square feet for an increase of 92,800 square feet and 4.9 acres of meandering channel were created. This project will increase the quality and quantity of rearing habitat for threatened salmon and steelhead in this key watershed for Puget Sound recovery, while also decreasing flood hazards over a large area. 5) At Minkler Road channel reconfiguration increased the conveyance more water and large wood, thus facilitating the stream flow of newly created meandering Hansen Creek channel.
The PCSRF 2014 funds were spent within the award period, work continues with PSAR funds.

Project Benefit    


To create a new channel to improve habitat complexity, via meanders, wood debris placement, and riparian plantings, along with increasing the conveyance such that more water and wood migrate through the system, benefitting ESA-listed Chinook, steelhead, coho, chum and pink
