City Mill Lock lowers vessels from the City Mill River (left) to the Waterworks River (right). The double set of lower lock gates, facing in opposite directions, indicate that sometimes the tide might raise the water level to the right higher than that on the left; on those occasions the right-hand gates will close to keep the water out. Because there are no corresponding gates at the upper end of the lock, navigation through the lock will not be possible at those times.
