1. An irrigation sprinkler comprising:
a sprinkler riser having an elevated position during irrigation and a lowered position when irrigation is stopped; the sprinkler riser comprising a rotating portion supporting a nozzle where the rotating portion rotates about a rotational axis; and,
a compartment including a radially inner wall and a radially outer wall, the radially inner wall and the radially outer wall each extending between a top and a bottom of the compartment, the compartment forming a compartment space extending at least partially around the sprinkler riser, the compartment space storing removable components of the irrigation sprinkler, wherein the radially outer wall is a curved portion of an outermost wall which extends entirely around the sprinkler riser so that the radially inner wall is asymmetrically spaced from the radially outer wall relative to the rotational axis; and wherein a first point along the outermost wall is located at a first radial distance from the sprinkler riser and a second point along the outermost wall is located at a second radial distance from the sprinkler riser, the second radial distance being less than the first radial distance;
wherein, along a plane perpendicular to the rotational axis of the rotating portion, the radially inner wall comprises a continuous uniform curvature that is different from a continuous uniform curvature of the radially outer wall such that the radially outer wall converges toward the radially inner wall and extends at least halfway around the rotational axis.
