About this map

The town of Dietrich serves as the focal point for this 1971 survey, illustrating a landscape defined by the careful management of water across volcanic terrain. The Union Pacific railroad cuts a diagonal path through the region, running parallel to the Milner Gooding Canal and providing a vital transport corridor for the community. The topography is dominated by expansive Lava fields and the prominent Crater Butte, a distinct volcanic landmark rising above the surrounding flats.

Water infrastructure is the key to local development here, with the Big Wood River and Little Wood River feeding an intricate network of irrigation features. Surveyors noted the presence of the Diversion Dam, a complex of Flumes, and a Siphon, all essential for directing water through the Main Canal. This hydraulic system transformed the arid Idaho plains into a managed agricultural zone, supported by local facilities like the town's central Landing Strip.
