2020 Map of Milner

About this map

Milner and the surrounding high desert terrain of the Magic Valley are defined by a sophisticated network of early 20th-century irrigation infrastructure along the Snake River. This 2020 edition reveals the intricate system of engineered waterways that transformed the arid landscape, including the North Side Main Canal, Milner-Gooding Canal, and the Twin Falls Main Canal. These canals radiate from the river near Milner Lake, supporting small settlements like Greenwood and McHenry. The topography is punctuated by Hazelton Butte, a prominent natural landmark that stands in contrast to the strictly organized grid of access roads and lateral ditches. The map meticulously documents the transition from raw river power to agricultural utility, tracing numerous named channels such as the Hazelton B Spill and the B-1 Ditch across the county lines of Jerome, Twin Falls, and Cassia.
