A discharge plume of water from the Conemaugh River Lake dam in Saltsburg, Pennsylvania, is designed intentionally so the water can increase its oxygen levels when exiting the dam to improve water quality downstream Oct. 22, 2021. The Conemaugh River Lake and the Loyalhanna Lake dams, managed by the U.S. Army Corps of Engineers Pittsburgh District, are located within eight miles of each other in Saltsburg, Pennsylvania. Their reservoirs flow downstream to join and form the Kiskiminetas River, which leads into the Allegheny River. The two dams are partners in providing navigation and reducing flood damage across the Pittsburgh region. (U.S. Army Corps of Engineers Pittsburgh District photo by Michel Sauret)
