About this map

The Snake River dominates this post-war landscape, carving a serpentine path through the eastern Idaho agricultural plains. This era reveals a sophisticated network of irrigation, where the Big Six Canal, Independent Canal, and Great Western Canal divert water to support a series of rural farming communities. The settlement pattern is anchored by small towns like Lewisville and Roberts, which were vital hubs for the surrounding farming families.

Genealogical interest is found in the local landmarks of the late 1940s, such as the Lewisville Cemetery, Central Cem, and early educational buildings like Midway High Sch and Grant School. The Union Pacific railroad corridor runs parallel to the river near Bassett, illustrating the transport link between these remote settlements and larger markets. The distinctive Lewisville Knolls rise above the flat basin, providing a geological landmark in an otherwise heavily engineered hydraulic landscape.
