Abstract
Systems, devices, apparatus, and methods of moving a door, over a water conveyances. Locking the door can be by rotating bolt heads attached to cams. Rotating heads causes cams to press the door against tracks. A strip can be compressed between the door and track to prevent flow. Slidable doors can move to allow water overflow. The door can slide so water can flow underneath. A secondary door can slide within an opening in a door. A half panel can have an upper opening located in a wall, to close or allow water flow. A channel can have grooves in sides of an opening, where a door can slide to different heights to close or allow flow.
