2011 Map of Owyhee Dam

About this map

Owyhee Dam and the northern reaches of Lake Owyhee dominate this high-desert landscape in eastern Oregon. The engineering of the Owyhee Project is prominently detailed, showing the intricate system of the North Canal and the Snively Siphon as they navigate the complex terrain. The Owyhee River carves through deep canyons, flanked by geological landmarks such as Balancing Rock, Pinnacle Point, and Deer Butte. Thermal activity is noted at Snively Hot Spring and a second Hot Spring further downstream. Upland areas are dotted with essential water management features for the region's arid climate, including the Chaney Reservoir, Oke Reservoir, and Mahogany Long Draw Reservoir. The road network, including Owyhee Lake Rd and the service paths like Upper Tunnel Rd, reflects the infrastructure necessary for both the dam's operation and the area's agricultural irrigation.
