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.
Effective immediately, Reclamation will require all boats launching at Lake Berryessa to participate in a seal program to prevent the spread of invasive mussels. All vessels wishing to launch at Lake Berryessa will be inspected. A red quarantine seal will be applied for 30 days during, which the vessel will not be permitted to launch. Vessels that have finished the 30-day quarantine may return to the lake and have the seal removed by authorized staff and will be allowed to launch. For more information on this updated protocol, please view the press release here: https://www.usbr.gov/newsroom/news-release/5031.
Recreation on this 1,100 acre impoundment is located 5 miles east of Prineville off U.S. 26.
