The primary objective of this project is to provide fish access into isolated tributary habitats and the off-channel floodplain habitat of Nason Creek. This was achieved through the construction of an opening in the BNSF railroad prism by installing an 89’ span bridge. The improved passage connects surface flows from the Coulter, Roaring, and Gill Creek basins to Nason Creek resulting in the reconnection of 14.9% of the Upper Nason Creek Basin. The project allows juvenile and adult Chinook and Steelhead access to 83.1 acres of high flow and 6.8 acres of low flow rearing and refuge habitat. Also, it provides steelhead access to 1 mile of lower Coulter Creek and steelhead and Chinook access to 0.75 mile of lower Roaring Creek.

Project Benefit    

Reconnect a stream channel to provide off-channel habitat for juvenile salmon. This project will connect Coulter, Roaring, Gill and Knutson Creek basins to Nason Creek, reconnecting nearly 15 percent of the upper Nason Creek basin.

      Project identified in a Plan or Watershed Assessment
      Restoration of Nason Creek is identified as the top priority for implementation of habitat actions in the Wenatchee Basin (UCRTT 2009) and in the Upper Columbia Salmon Recovery Plan (UCSRB 2007). Within Nason Creek, sidechannel and/or off-channel reconnection is a Tier 1 Action (Implementation Schedule Action ID NC-1880) and top priority for addressing limiting habitat factors and the recovery and long-term viability of salmonids
