Abstract: Many areas watered by prior art oscillating sprinklers are substantially rectangular. However, prior art oscillating sprinklers typically produce generally or substantially elliptical water distribution patterns. This geometric incompatibility causes problems and inefficiencies. Embodiments of the current invention include an oscillating sprinkler that automatically produces a substantially rectangular water distribution pattern. The substantially rectangular water distribution pattern may be produced by automatically controlling the distance from the sprinkler that streams of water travel before impacting the ground. This is accomplished by automatically and sequentially opening and closing and/or restricting flow to select nozzles at select points and within select portions of the oscillation cycle. A current invention oscillating sprinkler may reduce waste water, may reduce run-off waste water, and may automatically provide water to the corner areas of typical substantially rectangular areas to be watered.
