The Yakima River defines the central corridor of this region, separating the developed valley floors from the rising elevations of the Horse Heaven Hills to the south. This landscape is a complex network of water management, vital to the local agricultural economy, featuring the Sunnyside Canal, Mabton Feeder Canal, and Mabton E Lateral winding through the terrain. The city of Prosser serves as the primary hub, supported by the outlying areas of North Prosser and the small settlement at Apricot.
