1956 Map of Moses Lake South

About this map

Potholes Reservoir and the southern reaches of Moses Lake dominate this mid-century landscape in the Columbia Basin. The map records a moment of significant hydrologic and suburban development, showing the expansion of Westlake and the establishment of Moses Lake State Park. Along the intricate shoreline, features like Parker Horn and Pelican Horn are separated by islands such as Crest Island and Goat Island, while the vast Sand Dunes to the south illustrate the unmanaged terrain before later irrigation projects fully transformed the area.
