DESCRIPTION
This project will design a side channel re-connection near RM 2.3 on Nason Creek, just upstream of Lake Wenatchee. The site contains a relict oxbow and will require minimal excavation at the downstream end to provide a perennial connection to Nason Creek. The design will also evaluate the feasibility of an upstream connection either through shallow and narrow excavation or through placement of one to two in-stream log jams to increase activation at the upstream end. This phase of the project will include permit submittal and final design, which will lead to a restoration project benefitting Chinook salmon and steelhead trout. This project designed a perennial side channel re-connection near RM 2.3 on Nason Creek, just upstream of Lake Wenatchee. The site contains a relict oxbow and excavation at the upstream and downstream end that will create a perennial connection to Nason Creek. The design also included placement of two in-stream log jams to increase activation at the upstream end and increase sediment flushing at the downstream end of the connection. This phase of the project included permit submittal and final design. The implementation portion of this project was funded by BPA and completed in 2018.
