Nozzle orifice shapes and configurations associated with regulating and directing a flowing body of water over a water attraction riding surface for performing board-riding maneuvers is described. The nozzle orifice shapes and configurations according to the present invention includes shapes and configurations allowing for a flow of water over a ride surface which may include complex shapes which do not lend themselves to use with existing nozzle technologies. The present invention also includes nozzle arrays which may be made up of two or more nozzles arranged substantially adjacent or within close proximity to one another to create beneficial flow characteristics for performing board riding maneuvers on a complexly shaped riding surface.
