1949 Map of Hot Spring

About this map

The Bruneau River carves a deep path through Owyhee County, defining a landscape shaped by subterranean geothermal activity and early hydraulic engineering. Geologic features like the Indian Bathtub and numerous Artesian Wells point to the significant water resources that sustained this arid region. The infrastructure of the late 1940s is clearly visible, showing how water was managed via the Bruneau River Canal and the Buckaroo Ditch to support local ranching and the settlement at Hot Spring. Evidence of human adaptation to the river's flow is found at Buckaroo Dam and Harris Dam, while natural landmarks like Roberson Cave and the dramatic Bruneau Canyon highlight the varied topography. This survey captures a moment when the small-scale irrigation network and natural thermal springs were the primary drivers of life along the canyon floor.
