Bureau of Reclamation, Oregon.
The Owyhee Project lies west of the Snake River in Malheur County, Oregon, and Owyhee County, Idaho. The key feature is the Owyhee Dam, on the Owyhee River about 11 miles southwest of Adrian, Oregon. The dam is a concrete, thick-arch structure which was designed to carry about three-fourths of the water load by arch action, and the remainder by gravity action. The dam rises 417 feet above foundation in the river section and, at the time of its construction (1928-1932) was the world's highest dam. Owyhee Dam became a proving ground for theories being developed to assist with the design and construction of Hoover Dam, whose unprecedented size, 300 feet higher than Owyhee, required totally new construction methods.This 52-mile-long, 13,900-acre reservoir is located approximately 50 miles south of Ontario. Vehicle access is limited to the dam gravel road access to Leslie Gulch, Dry Creek, and Red Butte. Owyhee Irrigation District operates a visitor information center located in the historic construction office below the dam. Displays primarily focus on construction of Owyhee Dam and Irrigation Project. The facility is handicap accessible. Available fish species include largemouth bass, smallmouth bass, crappie, rainbow trout, brown bullhead, and yellow perch. Season open year-round. For reservations call 1-800-452-5687.
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.
