Bill Young Lock & Dam|website=www.lrp.usace.army.mil|access-date=2018-07-19}} The lock and fixed-crest dam were built by the U.S. Army Corps of Engineers as a part of an extensive system of locks and dams to improve navigation along the Allegheny River.
C.W. Bill Young Lock and Dam is located about 14.5 Miles up the Allegheny River from the Point in Downtown Pittsburgh. Upriver, the pool has an average water elevation of 734.5 feet above sea level and extends about 9.7 miles upriver to Allegheny River Lock and Dam No. 4. Downriver, Allegheny Pool No. 2 has an average water elevation of 721 feet above sea level and extends about 7.8 miles downriver to Allegheny River Lock and Dam No. 2. Thus Lock No. 3 lifts and lowers boats about 13.5 feet between the pools.{{cite web |url=https://www.lrp.usace.army.mil/Portals/72/docs/navigation/AlleghenyRiverNavigationChart.pdf |archive-url=https://web.archive.org/web/20130317205840/http://www.lrp.usace.army.mil/Portals/72/docs/navigation/AlleghenyRiverNavigationChart.pdf |url-status=dead |archive-date=March 17, 2013 |title=Allegheny River Navigation Charts Allegheny River Navigation Charts|website=army.mil|access-date=10 April 2023|date=January 2004}}
