1948 Map of Grand Coulee Dam

USGS Topo · Published 1970

About this map

The Grand Coulee Dam stands as the central monument of this post-war landscape, marking a massive transformation of the Columbia River into the sprawling Franklin D Roosevelt Lake. This 1948 survey captures the era when the new reservoir had recently redefined the geography of Lincoln, Grant, and Okanogan counties, while much of the surrounding plateau remained characterized by high-desert draws and isolated landmarks. The map details the emerging company towns of Coulee Dam and Grand Coulee, alongside older or smaller settlements like Elmer City and Seaton.
