Claim:
1. A drainage attachment for directing water from an elevated water source, the attachment comprising: an inlet section comprising an inlet section length and an inlet opening, the inlet opening comprising an inlet opening width, an inlet opening height, and a center point defining a longitudinal axis; an outlet section comprising an outlet opening, the outlet opening comprising an outlet opening width and an outlet opening height, the outlet section further comprising an uppermost structure extending between first and second relatively lateral structures, and a lowermost structure extending between the first and second relatively lateral structures; a transitional section between the inlet section and the outlet section, wherein the transitional section increases in width and decreases in height towards the outlet section; wherein the longitudinal axis extends in a first plane that is parallel to a second plane that divides a top portion and a bottom portion of the outlet section and bisects the first and second relatively lateral structures; wherein at least a fraction of the top portion of the outlet section is positioned below the first plane and the lowermost structure defines a third plane lying below an interior bottom of the inlet section, thereby aiding in gravitational passing of water; wherein the outlet opening width is greater than each of the inlet opening width and the outlet opening height, and shaped to reduce erosion from any water flow adjacent the outlet opening; and wherein the combined lengths along the longitudinal axis of the transitional section and the outlet section are longer than the inlet section length along the longitudinal axis.
