2010 Map of Triangle Reservoir

About this map

The settlement of Triangle serves as a lone outpost in this high-desert Owyhee County landscape, where water management is central to life on the land. A series of small-scale infrastructure projects, including Nettleton Dam, Rock Creek Dam, and Louisa Creek Dam, illustrate the critical importance of capturing seasonal flows from drainages like Rock Creek and Louisa Creek. The terrain is defined by a network of ephemeral and perennial watercourses that carve through the high plateaus, leading from the heights of Toy Mountain down into Cow Valley and along the winding North Fork Castle Creek.
