1943 Map of Isabella Dam

About this map

The Kern River and its south fork converge in a high mountain valley long before the modern reservoir reached its full extent, showing the original landscape of the Isabella Valley as it appeared in the early 1940s. The settlement of Kernville sits to the north, near the Big Blue Mill and the Kern County Airport, while the village of Isabella is positioned at the river junction. This era captures the valley's ranching and mining character, with numerous named properties such as Woodford Ranch, Doyle Ranch, and the Liebel Ranch scattered across the basin.
