The Portland District's latest ecosystem restoration project, inside Trestle Bay near Warrenton, Oregon, is relatively small. The Corps completed a similar project in 1995, breaching a 500-foot section of the South Jetty. Studies followed, evaluating the impact on migrating fish and other species that rely on the estuary. The studies showed that creating more openings would support efforts to......

The winter storms that regularly pound the Oregon and southern Washington coast are much like the hurricanes experienced on the East Coast. While challenging, these conditions give the Portland District an advantage when planning for climate......

Over the past 15 years, double-crested cormorants on East Sand Island consumed approximately 11 million juvenile salmon and steelhead per year. The U.S. Army Corps of Engineers has prepared a draft Environmental Impact Statement and management plan to reduce predation of ESA-listed juvenile salmon and steelhead by double-crested cormorants in the Columbia River Estuary. The Corps is......
