DESCRIPTION
The Upper White Pine Floodplain Reconnection Project removed anthropogenic site impacts (levee and infrastructure) to restore floodplain connectivity, channel migration processes, and improve in-stream aquatic habitat in Nason Creek (between RM 13.3 – 13.85). Within the project area, Nason Creek was artificially confined by two rip-rap lined levees that protected the CPUD powerlines on river left and the BNSF railroad on river right. Channelization created an entrenched, incised channel resulting in habitat simplification and disruption of natural stream channel processes such as floodplain inundation rate, channel migration, sediment deposition patterns, and large wood recruitment. These impacts reduced the quantity, quality, and access to stream, wetland, and off-channel habitats within the project area. This project removed approximately 0.5 mile of the river left levee and restored stream channel meanders to increase sinuosity and reduce confinement. Approximately 1,500 feet (.284 miles) of Nason Creek was re-aligned north of the existing channel in a new alignment through the floodplain wetland. These actions increased the flood prone area by 10 - 27 acres (2 year to 100 year event, respectively). This project also added large woody material to increase pool quality and quantity and will increase the availability of off-channel rearing. Increasing access to floodplain and off-channel habitat for ESA listed juvenile steelhead and spring Chinook improves rearing (feeding/foraging) and refugia from high water flows and predators. In order to accommodate stream restoration actions, six Chelan PUD power poles were removed from the riparian area and floodplain and that section of transmission line was re-located to White Pine road.
