This project completes a feasibility study to evaluate restoration options along the 5.8 mile Rinearson Slough where salmonid access has been restricted by dikes and impaired by elevated water temperatures, decreased flow, and invasive plant species. The site is located along the south bank of the lower Columbia River at mile 63 behind a railroad embankment that functions as a dike cutting off the connection to the Columbia. The floodplain is heavily impacted by residential and agricultural development. Restoration alternatives being considered include installing a tide gate at the mouth of the slough to allow tidal exchange and fish access to the site, channel excavation, installing large wood, and reconnecting the floodplain. An additional land acquisition component is also being considered.
