Implement the Habitat Restoration Program for the Columbia Estuary and Lower Columbia River

The work to be accomplished under this project will continue to institutionalize this effort as it implements the habitat restoration program for the long-term and takes action on beneficial, already-scrutinized habitat restoration projects in the short-term (three years). The outcome of this project will be increased survival of juvenile salmonids.Replace existing tide gate and culvert at Skipanon Slough with an tide gate that will remain open at all times except when very high tides or flood flows in river reach a specified elevation; create a culvert/tide gate connection through an existing levee. Restoration would include modifications to the causeway, improving other flow restrictions, and protection of existing wetland areas.Restoration at these islands would be primarily acquisition and protection, however some restoration opportunities exist to control invasive species and restore some wetland functions. Restoration of the area will include numerous dike breaches, tidegate removals, filling of drainage ditches, excavation of historic tidal channels, and revegetation with native species.
