1948 Map of Lewisville

About this map

The Snake River dominates this landscape of the upper Snake River Plain, creating a complex network of braids and secondary channels such as Roberts Slough and the Dry Bed. This mid-century environment is defined by an intricate irrigation system essential for local agriculture, featuring the Missionary Canal, Long Island Canal, and Great Western Canal. The Union Pacific railroad tracks run parallel to the river corridor, supporting small agricultural hubs like Roberts, Bassett, and Lewisville. The geography transitions from the riparian wetlands of the Market Lake Wildlife Management Area to the prominent Lewisville Knolls. Cultural landmarks such as Midway High Sch and the Lewisville Cemetery reflect the established community centers of Jefferson and Bonneville counties during this era of post-war development.
