The restoration strategy depends upon re-establishing tidal exchange with the Tillamook Bay, as well as hydrologic connectivity between the Wilson and Trask Rivers and their floodplains. The Southern Flow Corridor-Landowner Preferred Alternative Project (SFC-LPA) focuses on removing human alterations to allow the natural processes to restore and maintain the site’s ecosystem functions.
