Started in 2005, Fort Clatsop - Colewort Creek was a two phase tidal reconnection restoration project on National Park Service property in Clatsop County, Oregon.
In Phase 1, the Columbia River Estuary Study Taskforce (CREST), in partnership with the Lewis and Clark National Historical Park, restored tidal connection to 45 acres of floodplain near Astoria, Oregon. The property was formerly in private ownership but was acquired by the National Park Service as part of Fort Clatsop, prior to the restoration. Restoration actions included the removal of a tidegate and installation of a bridge to provide fish access to high quality rearing habitat along the Lewis and Clark River. Partners included the Conservation Fund, the Ness Family, the National Park Service, Clatsop County Road Department, Young's Bay Waterhsed Council, and the Young's Bay Diking District. Estuary Partnership funding was provided by BPA and the NOAA Restoration Center.
In Phase 2, additional restoration work was completed to enhance the hydrology within the site. Phase 2 restoration actions included removal of fill material to lower marsh elevations, excavation of tidal channels, and placement of large wood within the floodplain and tidal channels.
