1986 Map of Morrow Reservoir

About this map

Morrow Reservoir and Blair Trail Reservoir define the water management landscape of Elmore County during the 1980s. This survey records the complex drainage system of the Idaho high desert, where seasonal and perennial flows like Alkali Creek and Little Canyon Creek cut through the terrain. The presence of numerous named water sources such as Rustican Spring, Cold Springs, and Mud Springs indicates the vital importance of spring-fed points for local livestock and land use in this arid region. High-tension transmission lines cross the landscape, signifying the infrastructure development of the mid-20th century. The intricate contours trace the steep walls of Little Canyon and the winding course of King Hill Creek, providing a detailed look at the geographic character of the area before modern satellite mapping became standard.
