Multiple orientation rotatable sprinkler

A rotatable sprinkler including:

• a water outlet nozzle providing a pressurized axial stream of water along a nozzle axis;
• and
• a rotatable water deflector assembly, downstream of said water outlet nozzle and receiving said pressurized axial stream of water therefrom, said rotatable water deflector assembly being rotated during sprinkler operation by said pressurized axial stream of water about a rotatable water path deflector assembly axis, said rotatable water deflector assembly including:
• a first rotatable water path deflector portion;
• and
• a second rotatable water path deflector portion, which is user rotatable relative to said first rotatable water path deflector portion about a second rotatable water path deflector axis, thereby enabling user selection of at least one water distribution parameter,
• said first rotatable water path deflector portion including a first rotatable water path deflector generally planar portion, said first rotatable water path deflector generally planar portion being formed with a plurality of radially-extending protrusions.
