A U.S. Army Corps of Engineers flag flutters on a barge at the Montgomery Locks and Dam, operated by the Pittsburgh District, on the Ohio River in Beaver County, Pennsylvania, Aug. 2, 2021. A medium fleet crew began work at Montgomery L/D in late July, and they will spend approximately a month to replace and repair components of the gate system and valves.
