A turret type sprinkler comprising a base having inlet hose fitting for connection with a hose communicating with a source of water under pressure and a turret assembly mounted on the base for indexed rotational movement about a generally vertical axis. The turret assembly includes upper and lower cooperating annular members fixedly secured in cooperating relation providing a plurality of spray head structures spaced annularly about the axis of indexed rotation thereof. Each of the spray head structures includes a water inlet extending upwardly from a downwardly facing annular surface on the lower annular member in a position to be communicated with a water outlet on the base in one operative position of indexed rotation. Each of the spray structures also includes upwardly open pattern defining surfaces formed in the upper annular member and extending upwardly and outwardly with respect to the associated water inlet, and a water spreading element for spreading the water from the inlet onto the pattern defining surfaces.
