Disclosed is an apparatus for circulating water in a body of water including a simulated floating rock structure connected to a pump located remote from the body of water. Conduits place the pump, the body of water, and rock structure in communication so that water is drawn from the body of water and forced under pressure through the conduit connected to the floating rock structure. There is a nozzle element in the floating rock structure centrally located in the top of the floating rock structure connected to the conduit leading from the outlet of the pump so that water under pressure is forced through this nozzle. The conduit connected to the floating rock structure includes a slidable section that automatically increases or decreases the length of the conduit as the water level changes within the body of water. Valves are provided to control the flow of water so that the spray emanating from the nozzle element may be increased or decreased.
