A water vessel for providing water to livestock animals in tie stalls is described. The vessel features a sensor for providing water in response to a sensed presence of a livestock animal's head within the vessel. As water is provided to the vessel, the livestock animal is compelled to lift their head and thereby withdrawing their head from the region sensed by the sensor. In this way, the depth of water in the vessel is maintained within a predetermined range. The vessel also comprises a rim that is disposed sufficiently above the predetermined range of water levels that the livestock animal is compelled to lift their head in a substantially vertical fashion in order to withdraw their head from the vessel. This serves to reduce the spillage of water from the vessel.
