Four weeks later on September 27, 1937, the northwest lock gate is undergoing final adjustments. The control house is in the upper left corner and to its right is the lock gate operating mechanism consisting of an electrical motor and gear reduction unit. A pinion gear below the operating mechanism rotates against a rack mounted on a long arm attached to the lock gate to open and close the gate. (MWRD photo 23573)
