Lock and Dam 13 is located at mile 292.8 on the Arkansas River. The dam was designed to provide a minimum depth of 9 ft to Lock and Dam 14 at mile 319.7. Following initial operation of Lock and Dam 14 in January 1971, shoaling in the upstream end of Lock and Dam 13 Pool became a chronic problem, occurring each time flows exceeded 50,000 cfs. This study was conducted to develop a system of channel structures in the reach just downstream of Lock and Dam 14 that would appreciably reduce the required maintenance dredging without significantly increasing water-surface elevations or velocities determine the effectiveness of overdepth and overwidth dredging in delaying the need for required maintenance dredging and locate the optimum site for two mooring cells upstream of Lock and Dam 14.
