DESCRIPTION
The project is located on the lower reach of Chewelah Creek and the Colville River near the confluence. The goal of the project is to restore habitat function in the lower reach of Chewelah Creek and the Colville River between State Highway 395 and Alm Lane. The instream and riparian habitat of the project area is degraded by channelization and sediment loading. The current alignment of Chewelah Creek flows into the Colville River at an approximately 90 degree angle causing erosion of the opposite bank and flooding of adjacent property. The project will address persistent challenges related to the heavily modified (dredged and straightened) segment of the Colville River. The project will add a high-flow channel to Chewelah Creek and modify the floodways of Chewelah Creek and the Colville River. The project will improve instream and riparian habitat and improve the resilience of the channel/floodplain system. Potential site-specific stream enhancement include: riparian planting, bank stabilization, creation of a braided channel, channel terracing, re-meandering of the channel and introduction of large woody debris.
