Hildebrand Lock and Dam is a navigational lock and gated dam on the Monongahela River at Hilderbrand, West Virginia. (Hildebrand is a misspelling of Hilderbrand.) It is part of a series of dams that canalizes the Monongahela to a depth of at least for its entire length from Fairmont, West Virginia to Pittsburgh, Pennsylvania. It is maintained by the U.S. Army Corps of Engineers, Pittsburgh District. Hildebrand has a single lock chamber located on the left-descending river bank. The dam's upper pool extends upstream to Opekiska Lock and Dam, with its downstream pool being formed by Morgantown Lock and Dam. ==History== Construction on Hildebrand Lock and Dam began in 1950 and was completed in 1960.〔(USACE Pittsburgh District: Hildebrand Lock and Dam, accessed April 1, 2008 )〕 It replaced old Locks 12 and 13, timber crib structures completed in 1903.
