1971 Map of American Falls SW

About this map

The American Falls Reservoir and the Snake River dominate the eastern landscape of this 1971 survey, where Idaho's agricultural and industrial infrastructure meets the water's edge. The map captures a complex system of water management and transport, featuring the Union Pacific railroad corridor and a massive Canal system. Evidence of local ranching and rural industry is scattered across the Pleasant Valley terrain, from the Western Home Ranch to the Industrial Waste Pond and the nearby State Fish Hatchery. Natural hydrology is represented by Spring Hollow and Ferry Hollow, alongside vital springs such as Rueger Springs and Davis Springs. This edition is particularly valuable for its depiction of mid-century infrastructure, including the Deen Substation, a Filtration Plant, and a Gaging Station monitoring the river's flow.
