US Patent 11697913 Water flow control device

A water flow control device is provided that opens to allow water to leave a basin and pour into another pool of water. The water flow control device closes when the level in the pool of water is such that an influx of water could be returned to the basin. The water flow control device has a buoyancy apparatus that opens and closes the water flow control device based upon the level in the pool of water. The water flow control device also has a conveyance channel apparatus that directs water from the basin through the water flow control device in the event the buoyancy apparatus provides an opening to do so.
