Lock and Dam No. 3 is located about 14.5 Miles up the Allegheny River from the Point in Downtown Pittsburgh. Upriver, Allegheny Pool No. 3 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.[3]
The site has six contributing structures, the dam, the lock, an esplanade, the operations building, a gauging station, and a lockkeepers house.[4]
Two 2-story frame lockkeepers houses were constructed about 1907, with the older house at 301 Barking Road surviving.[5]
