The Tom Bevill Lock and Dam is approximately 1 mile southwest of Pickensville in Pickens County, AL. The lock is located on the left overbank about 332.7 river miles above the mouth of the Mobile River and is designed to maintain a minimum upper pool extending upstream to river mile 342.2 during low flows. The lock is 110 ft by 600 ft clear chamber dimensions. The dam consists of a gated spillway in the river channel and an adjacent 150-ft overflow weir on the right overbank. The lock is connected to the dam with a 150-ft abutment wall. A strong crosscurrent or outdraft existing in and around the upstream lock entrance causes difficulty for tow traffic navigating the lock. The purpose of the model study is to suggest possible solutions to improve and/or correct the outdraft for the approach of tows.
