About this map

Arid basin landscapes and early water management define this late 1940s survey of Owyhee County. The presence of the Grand View Irrigation District Canal in the northeast corner illustrates the critical role of engineered water systems in supporting settlement and agriculture in the high desert. Nearby, a cluster of Artesian Wells suggests localized attempts to tap into groundwater reserves where surface water was scarce. The terrain is characterized by a series of drainage systems, most notably Vinson Wash and McKeeth Wash, which flow toward the Twentymile Flat. These seasonal watercourses, including Birch Creek and Twentymile Wash, dictate the region's topography, marking the transition from high plateaus to the flatter basins used for seasonal range or early homesteading efforts.
