The Prineville Dam is a concrete gravity dam located on the Crooked River in Oregon, USA. Completed in 1964, it was built to provide irrigation, flood control, and hydroelectric power. The dam creates the Prineville Reservoir, which serves as a recreational area for fishing, boating, and camping. The dam is operated by the U.S. Bureau of Reclamation and plays a crucial role in managing water resources in the region. It has a total capacity of approximately 100,000 acre-feet and helps support local agriculture by supplying water for irrigation during dry seasons.
