Lake Banks and the massive Grand Coulee dominate this mid-century landscape, illustrating a period of intense hydraulic and agricultural transformation across Central Washington. The map details the complex irrigation infrastructure of the era, from the North Dam and South Dam to the extensive Quincy Lateral and various pumping stations that redistributed water from the Columbia River. Industrial and military footprints are prominent, including the Utah and Idaho Sugar Refinery near Moses Lake, alongside Ephrata Air Base and Larson Air Force Base.
