ABSTRACT:
A water circulating device designed to be installed in a pond or the like for circulating warmer subsurface water to the surface to prevent freeze-over of the pond. The device comprises a framework having a base section which rests on the floor of the pond and an upright section extending up from the base section, a long substantially rigid water conduit mounted on the base section for pivoting about a generally horizontal axis, a pump for pumping water through the conduit from its intake end to its discharge end, and a float connected to the conduit and mounted for up and down movement on the upright section of the framework whereby when the framework is in the water the float rises and pivots the conduit to an inclined position in which the intake end of the conduit is disposed for intake of warmer subsurface water and the discharge end is disposed for discharge of the warmer water at a location adjacent the surface of the water to prevent freeze-over of the pond.
