Bureau of Reclamation, Oregon.
Ochoco Dam and reservoir are major features of the Crooked River Project. Ochoco Dam, a hydraulic-fill structure on Ochoco Creek east of Prineville, Oregon, was constructed immediately after World War I as part of the Veterans Farm Settlement program undertaken by the state of Oregon. The left abutment of the dam is an alluvial fan and the right abutment is a slide mass consisting of fine earth and rock. The dam is 125 feet high with a crest length of 1,350 feet. The State Parks located on both the Prineville and Ochoco Reservoirs are among the most heavily used in Oregon. Ochoco Reservoir has 8 miles of shoreline. Available fish species include rainbow trout and brown bullhead. Season open year-round. Reservoir acre feet and total reservoir capacity and cubic feet/second release rates for rivers below Deschutes River Basin reservoirs and select river locations are updated daily and graphically provided.
Recreation on this 1,100 acre impoundment is located 5 miles east of Prineville off U.S. 26.
