Frenchman Hills Lake sits at the heart of this mid-1980s Grant County landscape, where the high desert terrain is defined by complex water management and agriculture. The map illustrates a transitional period for the Royal Slope, as irrigation infrastructure like the Frenchman Hills Wasteway and the Frenchman Hills Pumping Plant transformed the arid environment. To the south, the grid of Royal City is visible near the Royal Substation, surrounded by numerous Storage Bins that hint at the region’s productive farming output. Conservation and utility coincide here, with the Desert Habitat Management Area bordering the wasteway and a massive Transmission Line cutting across the Frenchman Hills. Researchers can trace the layout of early landing strips and local industrial features like a Borrow Pit and Sewage Disposal Ponds that supported the growing community.
