2010 Map of Owyhee

About this map

The Idaho State Penitentiary and the Idaho State Correctional Institution dominate the northern landscape of this 2010 Ada County survey, highlighting the area's role in the state's institutional infrastructure. Situated south of Boise, the terrain is defined by a network of seasonal watercourses including Tenmile Creek, Indian Creek, and Sand Creek that cut across the high desert plain. Small settlements such as Owyhee and Pleasant Valley are linked by long thoroughfares like Kuna Mora Rd and Pleasant Valley Rd. In the northeast, the Blacks Creek Dam creates the Blacks Creek Reservoir, a significant water feature in this arid environment. The map also captures specialized land uses such as the Blacks Creek Rifle Range and Airstrip Access, illustrating a mix of public safety, water management, and rural transport.
