  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 9 feet (2.7 m) 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 7.4 miles (11.9 km) upstream to Opekiska Lock and Dam, with its 6.0-mile (9.7 km) downstream pool being formed by Morgantown Lock and Dam.
