Upper Wenatchee RM 40.5-41.5 Concept. Design

This project will evaluate the mainstem channel and adjacent floodplain wetland complexes on river left (~RM 40.5-41.5) to identify and develop restoration actions that will improve in-stream conditions, reduce erosion and reconnect the floodplain. This effort will include a focus on engaging with WDNR landowner and one adjacent landowner as part of the concept development process to determine project opportunities. We propose to complete all work necessary to evaluate the site, develop and analyze alternative restoration strategies and prepare conceptual designs for the preferred alternative, and anticipate hiring a contractor to complete tasks including onsite data collection, compilation of existing data, hydraulic modeling, opportunities and constraints analysis, and development of conceptual designs. 

Increase the quantity and quality of accessible off-channel rearing habitat for juvenile spring Chinook Salmon and steelhead in the Upper Wenatchee River. Provide winter rearing habitat and refugia-type habitat during spring and other high flow events. Incorporate the restoration of natural processes in the project goals and clarify project constraints in the alternatives development stage.
