Abstract
The livestock watering tank includes a top, bottom and sidewall. The top wall has an opening for access to the water. The opening is closed by a float. The animal drinks by pushing the float down into the water with its mouth, causing the float to partially submerge so that water is exposed and may be drunk. The float rises back to its natural position after the animal finishes drinking. The float has a port for allowing water or other weighted substance to be introduced into it. The addition of the substance into the float generally neutralizes the buoyancy of the float with respect to the water in the tank, thereby decreasing the amount of force necessary for the animal to submerge the float for drinking.
