1948 Map of Ucon

About this map

The intensive irrigation network of the Upper Snake River Valley defines the landscape around Ucon and Iona, where a complex system of waterways like the South Branch Harrison Canal and Farmers Friend Canal transformed the high desert into productive farmland. Settled at the intersection of these vital water lines and the Union Pacific railroad, communities such as Lincoln and Beachs Corner grew to serve the agricultural needs of Bonneville County. The map reveals the expansion of Idaho Falls at the southern margin, while also preserving localized landmarks like the St Leon School and Lincoln Cem. This survey, updated with purple revisions from 1976, shows how early 20th-century settlement patterns and water rights—represented by dozens of named ditches such as the Biby Ditch and Koster Lateral—remained the backbone of the region's economy decades later.
