The Montgomery Point Lock and Dam Project is a navigation project designed to improve navigation conditions in the White River Entrance Channel located in Arkansas. This Channel constitutes the first segment (10 miles) of the McClellan-Kerr Arkansas River Navigation System. The project features a dam consisting of a unique 300 ft. wide gated navigable pass, a 200 ft. wide ungated overflow spillway, and a 110 ft. wide by 600 ft. long navigation lock. The navigable pass includes 10 hydraulically operated hinged crest gates, placed side by side. All gates are normally submerged in the lowered position, allowing vessels to pass over them. As the downstream Mississippi River stages fall, the gates are raised to maintain minimum navigable depths upstream, and vessels pass through the lock. The project includes a unique dewatering structure for maintaining 6 navigable pass gates simultaneously, and a SCADA system for remote operation of the facilities.
