The project area encompasses the entire Lower White Pine Reach (RM 4.5 - 14.3) of Nason Creek. This is a 2.1-mile-long segment of Nason Creek between river mile (RM) 11.55 and RM 9.45. The focus of this proposal is to seek funding for the upstream B+ connection at RM 10.7 and a short connector channel that will connect the B+ bridge to the existing disconnected channel. Construction of the Great Northern Railway in the 1890s disconnected two large channel meanders, the downstream one is 5,494 linear feet and the upstream one is 4,755 linear feet and floodplain areas that total 148 acres. The primary objective of this project is to provide hydraulic connectivity between isolated habitats and the mainstem of Nason Creek. This will be achieved through the construction of downstream and upstream openings in the BNSF railroad prism and the installation of 89’ span bridges. The improved hydraulic connectivity will connect surface flows from the Coulter, Roaring, Gill, and Knutson Creek basins to Nason Creek resulting in the reconnection of 14.9% of the Upper Nason Creek Basin. In addition, it will allow 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. In addition, it will provide steelhead access to 1 mile of lower Coulter Creek and steelhead and Chinook access to 0.75 mile of lower Roaring Creek. In total, this project will connect 148 acres of isolated Category 1 wetland/floodplain habitat or 38% of the disconnected floodplain in this reach.
