DESCRIPTION
The Chelan County Natural Resources Department (CCNRD) is seeking funds for the final design and permitting for the Nason Creek N1 Floodplain Reconnection project. This project will reconnect Nason Creek to a disconnected floodplain area that is located just downstream from Coles Corner near State Route 207. Construction of SR 207 in the 1950’s disconnected Nason Creek from 8.7 acres of floodplain and forced the river to make a 90 degree turn against the road prism at the location of a possible inlet to the disconnected floodplain area. The Wenatchee Watershed Planning Unit Habitat Subcommittee has identified this disconnected floodplain (N1) as a priority reconnection opportunity within the Nason Creek Kahler Reach Assessment recently completed by the United States Bureau of Reclamation (USBR 2009). Floodplain reconnection will address limiting factors for endangered spring Chinook, endangered steelhead and threatened bull trout by improving floodplain function. CCNRD is currently evaluating reach scale alternatives to a draft design proposed by WSDOT to install riprap and rock barbs to the State Route 207 road prism in the vicinity of the 90 degree turn. If the final design and permitting are funded, CCNRD will be able to work with WSDOT to seek funds for construction of a more fish friendly alternative to the rip rap proposed. This project has not been previously reviewed by SRFB.
