Safety on the Horizon
Maj. William Yount, a project engineer for the U.S. Army Corps of Engineers Pittsburgh District, watches as a crew installs additional safety buoys at the Allegheny River Lock and Dam 2 in Pittsburgh, Pennsylvania, June 10, 2021. The Pittsburgh District recently added horizontal buoys on the Allegheny and at the Dashields Lock and Dam on the Ohio River to provide even more visible signs to warn recreational boaters from going over the dam. The dams on the Allegheny River and at Dashields are submerged, also known as fixed crest dams, which make them difficult to see from upstream.
