A method of operating a swimming pool with a circulating water flow. The method including the steps of discharging a jet of water and splitting the flow of water. The discharging step including the discharging of a jet of water from an outlet at a head end of the swimming pool into a swimming compartment, whereby the jet of water flows in a primary flow path toward a foot end of the swimming compartment. The splitting step including the splitting of the flow of water to define two circuitous flow paths, each said flow path having a return flow path flowing within said swimming compartment in a direction generally opposite to said primary flow path back toward said head end.
