Mark Gard, U.S. Fish and Wildlife Service biologist, collects sediment samples while surveying Beale Lake at Beale Air Force Base, California, July 10, 2019. The Air Force collaborated with the USFWS to remove Beale Lake Dam and restore the natural flow of the creek there. The project, completed in late 2020, makes it easier for threatened fish to travel upstream and spawn. (Air Force photo by Staff Sgt. Alexandre Montes)
