The planning stages of the project involved an evaluation of three restoration scenarios that were presented to the private landowner with the goal of achieving a more natural inundation regime through modifications to existing levees and tide gates on the 62 acre property. The preferred alternative was developed into a design that involved a levee breach and tidal channel construction to reintroduce 32 acres of floodplain to tidal waters of the Columbia River. The project also includes construction of log structures, beaver piles, hummocks with turtle nesting gravel, and upland areas with native grasses to improve habitat for multiple native species including juvenile salmonids, western pond turtles, red-legged frogs, beaver, and Columbia white-tailed deer.
Construction was completed in September 2015. Drone footage provided by the Lower Columbia Estuary Partnership to monitor the site's progress can be viewed here: Batwater Station Flyover
