About this map

Lost Valley and its surrounding water sources define this high-elevation corner of Owyhee County, where a series of catchments and natural springs sustain the arid landscape. The area is marked by the presence of Dry Cr Reservoir Number Four, Dry Cr Reservoir Number Seven, and Dry Creek Reservoir Number Six, indicating a managed water system designed to support ranching or local agriculture.

The winding course of Battle Cr and Big Springs Cr carves through the terrain, leading toward distinctive landmarks such as Dollar Butte and the depressions of Bull Basin. Cultural features are limited to the remote Battle Creek Rd and the identified site of Twin Bridges, emphasizing the sparsely populated, open-range character of the region. This 2017 survey provides a clear view of the complex hydrography, from Wildhorse Spring to the Upper Lost Valley Spring, essential for understanding the environmental geography of this Idaho wilderness.
