River water overtops the miter gates at Dashields Locks and Dam, operated by the U.S. Army Corps of Engineers Pittsburgh District on the Ohio River near Coraopolis, Pennsylvania, April 4, 2024. The high river levels shut down operations at Dashields as well as at most navigation facilities across the three main rivers in the Pittsburgh District. The city of Pittsburgh and the surrounding region faced two weeks of back-to-back heavy rain in April that resulted in river levels reaching the Point State Park fountain and submerging streets known as Pittsburgh’s “bathtub.” However, if it had not been for the region’s reservoirs, managed by the U.S. Army Corps of Engineers Pittsburgh District, flood waters would have reached the entire length of Liberty Avenue, a road stretching across more than 25 city blocks. The Pittsburgh District manages 16 reservoirs built over several decades to hold back water and reduce the damage of catastrophic floods. Since 1938 when the first dam was built in the region, the Pittsburgh District prevented more than $14 billion in flood damages to homes, businesses and infrastructure.
