An animal watering apparatus having a tank for storing a supply of water. The tank has a top wall having a first tubular baffle surrounding an opening for accommodating a float valve assembly operable to supply water to the tank chamber. A second tubular baffle surrounds a drinking well. The first and second baffles are spaced from the walls of the housing to allow water to circulate about the baffles to minimize the freezing of the water in the float valve assembly and the drinking well. A closure associated with the drinking well minimizes the freezing of the water in the drinking well. The cover is a movable open float located within the drinking well. A second form of the cover is a pivotal lid that is moved by the animal to an open position to provide access to the drinking well.
