Royal City serves as the primary hub in this agricultural landscape of Grant County, where the sophisticated irrigation networks of the Columbia Basin Project are fully realized. The town is situated on the Royal Slope, a region defined by its productive orchards and vineyards, supported by extensive water infrastructure like the West Canal and Crab Creek Lateral. To the north, the terrain rises into the Frenchman Hills, where the Frenchman Hills Wasteway feeds into Frenchman Hills Lake, illustrating the complex management of water runoff in this high-desert environment.
