This section of Nason Creek was re-located in the late 1950's when the BNSF railroad was built in it's current location. From RM 13.3 to RM 13.8, Nason Creek flows east between two constructed levees that protect the CPUD powerlines to the north and the BNSF railroad to the south. There is no spawning for spring Chinook or steelhead within the project area, however, spawning is present just upstream and downstream of the project area. The existing bed is incised due to channelization and Nason Creek is disconnected from the adjacent 30 acre floodplain wetland to the north. This project will remove ~0.5 mile of the river left levee, re-locate ~1,400 linear feet of straightened mainstem into a new meander alignment, provide over eight acres of floodplain rearing habitat, and re-connect ~30 acres of channel migration zone. This project will re-locate the CPUD powerlines out of the floodplain to accommodate stream restoration actions. The primary goal of the project is to improve and increase salmonid habitat in 0.5 mile of Nason Creek to increase the abundance and productivity of ESA-listed UCR spring Chinook salmon and UCR steelhead. This project will address the #1 ecological concern per the Biological Strategy by enhancing peripheral and transitional habitats in the #1 priority area in the Wenatchee Basin. This project will also address the #2 ecological concern in Nason Creek by improving in-stream complexity through the addition of large wood (332 pieces).
