Upriver, Allegheny Pool No. 5 has an average water elevation of 757 feet above sea level and extends about 5.9 miles upriver to Allegheny River Lock and Dam No. 6. Downriver, Allegheny Pool No. 4 has an average water elevation of 745.4 feet above sea level and extends about 6.2 miles downriver to Allegheny River Lock and Dam No. 4. Thus Lock No. 5 lifts and lowers boats about 11.6 feet between the pools.
The Operations Building, or powerhouse, is a utilitarian two-story building in a vernacular Moderne style. The lock and 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.
It was listed on the National Register of Historic Places in 2000.
