The Columbia River dominates this 2014 survey, carving a complex network of channels and islands between Washington and Oregon. On the Washington side, Cathlamet serves as a focal point, with its harbor protected by the Elochoman Slough Marina and connected to the larger river system via the Cathlamet Channel. The geography here is defined by significant estuarine features like Puget Island, Tenasillahe Island, and the many winding sloughs including Bernie Slough and Brooks Slough. These waterways dictate the local infrastructure, from the Puget Island Bridge to the Puget Island Ferry Landing.
