2017 Map of Lake Walcott SE

About this map

Lake Walcott and the winding course of the Raft River define this corner of southern Idaho near the border of Cassia and Blaine counties. This 2017 survey shows a landscape of agricultural sections and sagebrush terrain, bisected by the modern path of Interstate 86. The map provides a detailed view of local infrastructure, including family-named routes like Hegsaw Ln and the long stretches of Yale Rd and S Yale Rd. In the southeastern corner, the topography drops into Heglar Canyon, where Heglar Canyon Rd follows the natural drainage. This area illustrates the late 20th-century transition of the high desert through irrigation and the establishment of a robust county road network that supports the region's ranching and farming operations.
