Abstract: An example water circulation device is configured for mounting within a livestock watering reservoir, and generally includes a mount, a housing, and a nozzle. The mount is configured to facilitate mounting of the water circulation device within the livestock watering reservoir. The housing is coupled to the mount, extends along a longitudinal axis, and includes helical channels and apertures distributed amongst the helical channels. The nozzle is mounted in the housing and configured to discharge water at an oblique angle relative to the longitudinal axis to thereby cause circulation of water within the housing. Moreover, the housing is configured to discharge circulating water via the plurality of apertures in a manner that generates eddy currents in an area of the livestock watering reservoir that is positioned outside of the housing.
