The overall objective of the Swan Lake Restoration Project is to improve the habitat quality and ecological function of Swan Lake. The Swantown Sub-basin is the sixth largest drainage in WRIA 6, covering about 18.0 sq km. It is located on the west side of north Whidbey Island west of Oak Harbor and south of Ault Field. The project is located in a coastal marsh currently not accessible to unimpeded tidal flushing or salmonid access, known as Swan Lake (or also “Swantown Lake”, “Swantown Marsh”, “Bos lake”, “West Beach Lake”). Swantown Creek flows into the coastal wetland therefore the project occurs in a pocket estuary.
A previous SRFB project (#09-1459) funded a preliminary feasibility study that focused on the historic character and function of Swan Lake. That work, completed in the fall of 2010, was considered the first step in the completion of a larger engineering feasibility assessment to identify potential restoration alternatives, and confirmed additional investigation was warrented.
Work to be undertaken in support of completing the engineering feasibility assessment will include more detailed topographic and bathymetric mapping, wave and littoral drift assessment, wetland functional assessment, inlet analysis, reference site analysis, infrastructure analysis, and more development of conceptual plans for several alternatives.
