The Millers Ferry Lock and Dam project provides for a lock and dam at mile 142.2 on the Alabama River and a power plant in an earth dike about 3000 ft downstream of the main dam. The structures will consist of an overflow embankment on the right overbank, a 1012-ft-long gated spillway with 17 gate bays, an 84- by 600-ft lock left of the spillway, an earth dike extending downstream to the powerhouse intake section, and an earth dike extending normal to the river. The lock will have a maximum lift of 48 ft. Tests were conducted in a 1:100-scale, fixed-bed model to determine the adequacy of the proposed design and to develop modifications to overcome or minimize adverse conditions. (Author).
