2017 Map of Triangle Reservoir

About this map

The settlement of Triangle serves as a lone anchor in this high-desert reach of Owyhee County, where a network of seasonal drainages and springs dictates the movement of people and livestock. Water management is central to the landscape, evidenced by the Triangle Reservoir and the White Horse Reservoir situated among the draws of the Owyhee Plateau. Historically significant routes like Triangle Rd and Antelope Ridge Rd skirt the edges of prominent geographical features such as Antelope Ridge and the Cow Valley basin. The map documents an intricate system of ephemeral creeks including N Fork Castle Cr and Cow Valley Cr, alongside vital watering holes like Stageroad Spring and Buckroo Spring that have long supported the region's ranching operations.
