Owyhee Reservoir, body of water
Owyhee Reservoir is a large body of water in eastern Oregon stretching roughly 53 miles through rugged landscape. The water sits surrounded by steep canyons and volcanic rock formations, with an open desert terrain on all sides.
Owyhee Reservoir was created in 1932 when the Owyhee Dam was built during the Great Depression. The massive concrete structure became a model for later dam engineering and was originally designed to supply water for farming irrigation.
The reservoir takes its name from the Owyhee River, formed where three streams converge. The area draws visitors seeking solitude and a direct connection with the natural landscape away from development.
Access is easiest from Adrian following rural roads, with high-clearance vehicles recommended especially after rain. Boat ramps on the northern end near the dam and another at Leslie Gulch allow water access for fishing and recreation.
The Owyhee Dam was an early milestone in concrete engineering and served as a model for later structures like Hoover Dam. Visitors can explore the dam's visitor center to learn how this engineering feat was accomplished.
