2020 Map of Frenchman Hills Lake

About this map

Royal City stands at the southwestern edge of a landscape defined by the Columbia Basin Project's intricate water management systems. This 2020 topographic study highlights the agricultural development of the Royal Slope, where engineered features like the W Canal, Crab Cr Lateral, and the Frenchman Hills Wasteway redirect water across the arid terrain. The map captures the interface between these man-made irrigation networks and natural geological formations, including the prominent rise of the Frenchman Hills and the sunken topography of Red Rock Coulee and Natural Corral. Local utility and landmarks are visible through Christensen Field and the scattered wetlands of Frenchman Hills Lake and Red Rock Lake, illustrating how contemporary land use has adapted to the region's basalt-carved environment.
