Agricultural development and water management dominate this Grant County landscape, anchored by the Wheeler settlement and its nearby Sugar Beet Refinery. The mid-century expansion of the Columbia Basin Project is evident through the engineered path of the East Low Canal, which cuts across the natural drainages of Rocky Coulee and Sand Coulee. This intersection of topography and irrigation infrastructure illustrates the region's transition from dry coulee country to a productive farming hub.
