    USACE Completes New Squadron Operations and Aircraft Maintenance Facility at Beale AFB, Enhancing Mission Support for the 940th Air Refueling Wing

    With a ribbon cutting timed for 9:40 a.m. Friday in honor of the 940th Air Refueling Wing, the U.S. Army Corps of Engineers completed a new Squadron Operations and Aircraft Maintenance Unit complex that will support refueling, maintenance and mission-planning operations for years to come. The more than 43,000 square-foot facility consolidates the Operational Support Squadron, Aircraft Maintenance Unit and Aircrew Flight Equipment into one modern building. With operations, maintenance and aircrew preparation located under the same roof, crews can move more quickly from planning to on the aircraft, and maintenance teams can coordinate directly with operators. Air Force Colonel Andrew Gray, commander of the 940th Air Refueling Wing, said the facility represents a long-awaited milestone.

    An aerial view shows construction of the fish passage structure along the west bank of the Sacramento River in Yolo County, California, on June 5, 2025. The structure is part of the Sacramento Weir Widening Project managed by the U.S. Army Corps of Engineers Sacramento District, which will create an 8,600-foot "double hybrid technical fishway" for endangered salmon, steelhead and sturgeon. The $350 million project combines flood control infrastructure with fish passage capabilities to protect threatened species during high-water events.

    Sacramento Weir Fish Passage: Offers Lifeline to Threatened and Endangered Fish Species in California's Central Valley

    The U.S. Army Corps of Engineers has completed a groundbreaking 1.6-mile "fish highway" designed to prevent thousands of endangered salmon, steelhead, and sturgeon from becoming stranded during flood events in the Sacramento River system. The $350 million double-channel fishway connects the Sacramento River to Tule Canal, accommodating fish up to 10 feet long through two parallel passages. Unlike traditional fish ladders, this system handles the unique challenge of serving both downstream-migrating juvenile salmon and upstream-spawning adult sturgeon during peak flood season from December to March. The innovative design addresses critical survival needs for species protected under the Endangered Species Act. Expected to be fully operational by winter 2026, the project represents a major advancement in balancing flood protection with wildlife conservation.
