Royal Camp sits at the base of the Frenchman Hills, serving as a central point in this mid-1980s landscape of managed desert and irrigation engineering. To the north, the Desert Habitat Management Area and Potholes Habitat Management Area surround the Potholes Reservoir, showing a complex system of drainage and conservation. The terrain is defined by the Winchester Wasteway and the Frenchman Hills Wasteway, which move water across the arid basins. Agriculture and utility infrastructure are prominent, with numerous storage bins, a Pumping Station, and the Crab Creek Lateral servicing the Royal Slope. This survey provides a technical look at the region’s water management history, including the West Canal and several siphons that traverse the hilly landscape, alongside industrial features like a Gravel Pit and Spoil Bank.
