    The U.S. Army Corps of Engineers, Little Rock District is currently conducting dewatering maintenance operations at David D. Terry Lock and Dam near Scott, Ark. This is the first time this specific lock chamber has been dewatered since 2000.

    The closure structure was in place by Aug. 27 and maintenance workers began pumping water out of the lock chamber. The chamber was empty of water by the end of the day on Aug. 28.

    The lock was dewatered to inspect the structural integrity of underwater components, complete critical maintenance task and perform multiple other inspections.

    During the dewatering the major tasks performed will be the inspection and repair of the metal components of the lock gates. Especially components that are continually under water.

    The lock chamber of David D. Terry Lock and Dam measures 110 feet wide and 600 feet long.

    Maintenance is very critical to ensure the lock stays operational. This year approximately 10 million tons of commodities has passed through David D. Terry Lock and Dam.

    David D. Terry Lock and Dam is part of the McClellan-Kerr Arkansas River Navigation System which is celebrating its 50th Anniversary this year.
