1979 Map of Twin Falls NE

About this map

The North Side Main Canal and its intricate network of distribution channels, such as the D 5 Ditch, define the agricultural landscape of Jerome Co. in this late 1970s survey. This map illustrates the vital infrastructure of Idaho's Magic Valley, where the Union Pacific railroad cuts a diagonal path through a grid of section lines and irrigation works. Industrial and community hubs are visible throughout the territory, including a local Grange Hall, a Substation, and the No 4 Pumping Station located near several Diversion Dams. Beyond the irrigated fields, the terrain is marked by extractive sites like Gravel Pits and a solitary Prospect, reflecting the local economy's reliance on both the soil and the underlying geology. The dense distribution of wells across the sheet further underscores the intensive water management required for the region's development.
