This project restores hydrologic connection to the Columbia River by removing/modifying existing flow control structures. Additional activities include placing large wood, controlling invasive species, replanting native vegetation, and excavating. The 100-acre site is located within 500 acres of US Forest Service owned property at the Sandy River Delta to the east of Sun Dial Island at Columbia River mile 122. The site historically was a mix of tidal forested and palustrine wetland floodplain habitat, but is now dominated by invasive plants (Himalayan Blackberry, Reed Canary Grass). River flow regulation and human manipulation for land use has resulted in the site being mostly disconnected from the main stem Columbia.
The project is being managed by the Estuary Partnership, with funds from multiple sources, and collaboration with the US Forest Service.
