Pineview Dam
Encyclopedia
Pineview Dam is located in the Ogden River Canyon
, 7 miles (11 km) east of Ogden, Utah
. It was developed as a means of providing reliable irrigation to 25,000 acres (100 km²) located between the Wasatch mountains and the Great Salt Lake
. It was built as part of the Ogden River Project, which included the Pineview Dam and Reservoir, Ogden Canyon Conduit, Ogden-Brigham Canal, South Ogden Highline Canal and a gravity-pressure distribution located in the South Ogden Conservation District.
. The western half of present-day Huntsville
is located between the central and southern bays of Pineview Reservoir. State Route 158 crosses the dam and runs adjacent on the north and west, former State Route 166 on the north and east, and State Route 39 on the southeast and south.
irrigated approximately 3,000 acres (12 km²) of land in the Ogden area before 1900. Increasing diversions lead to a shortfall of irrigation flow during late summer months. The Geological Survey in 1921 established stream gauging stations along the river. A storage reservoir recommendation was made shortly thereafter by the Bureau of Reclamation, and investigations continued until 1932. The Pineview site was then adopted for a 30000 acre.foot reservoir.
President Roosevelt authorized the Ogden River Project on November 16, 1935. Fund allotment had begun in 1933 under the National Industrial Recovery Act
. Construction began on September 29, 1934. Completion of the Pineview dam and Ogden-Brigham Canal occurred in June 1937. The South Ogden Highline Canal was constructed between 1938-1941.
Its construction is a zone earthfill dam
type containing 15,500 cubic yards (11,800 m³) of earth, rock and riprap
materials. The crest of the dam is at 4,908.0 feet (1496.0 m), is 30 ft (9 m) wide and 600 ft (180 m) long. Its initial height was 103 ft (31.4 m), resulting in a 44175 acre.foot capacity. The later Weber Basin Project increased the height of the dam to 137 ft (41.8 m), enlarging the capacity to 110150 acre.ft. By using radial gates, the dam functions with an overflow, channel-type spillway allowing for a flow rate of 10,000 cubic feet per second (280 m³/s).
The Ogden City Conduit is fed by a 72 and 75-inch (1.83 and 1.91 m) conduit at 2,300 cubic feet per second (65 m³/s). A stillout is fed from the same conduit through a 60-inch (1.5 m) outlet. A wye adapter on the 72 inches (1,828.8 mm) conduit allows additional discharge into the stillout, while 42 inches (1,066.8 mm) conduit feeds the Ogden City filtration plant located downstream. At 4.7 miles (7.6 km) down the Ogden River Canyon, the Ogden River Conduit splits into the Ogden-Brigham and South Ogden Highline canals. The Highline canal is fed through a 36-inch (0.91 m) diameter, 360 ft (110 m) long steel siphon suspended across the mouth of the canyon. The Ogden-Brigham canal has a flow rate of approximately 120 cubic feet per second (3.4 m³/s), while the Highline canal flows at 35 cubic feet per second (1.0 m³/s) over 5.2 miles (8.4 km).
The reservoir also acts as a recreational area located very close to Ogden and the nearby areas. Camping, boating, water-skiing and personal watercraft use, as well as trout, bass, crappie and wall-eyed pike fishing are popular activities in the recreational area. Nearly one million people visited the area in 1996.
Flood control has been estimated at nearly ten million dollars between the years of 1950 and 1999. The capacity of the dam and its ability to discharge water at up to 1600 cubic feet (45.3 m³) per second into the Ogden River have proved beneficial during times of intense water accumulation.
Pineview also provides hydroelectric power to the grid via a 2,500 horsepower (1,860 kW), horizontal Francis turbine
coupled to an 1,800 kW turbine. This project was completed in 1991, and diverts water from the 75 inches (1,905 mm) conduit, returning it after use. The operational capacity is rated between 130 and 300 cubic feet per second (3.7 to 8.5 m³/s).
Pineview Reservoir is home to the tiger muskie
, a sterile hybrid fish. These fish have a torpedo shaped body, with vertical "tiger" striping on its sides. They also have many sharp canine like teeth. It is one of only three lakes in the state of Utah that house these fish. It is not uncommon for a tiger muskie to grow up to 3–4 feet in length and weigh as much as forty pounds.

Benefits
At present capacity, the Pineview Reservoir is capable of irrigating 24,801 acres (100.37 km²) of land. This greatly improved irrigation capacity and distribution, allowing for the growth of all manner of crops.The reservoir also acts as a recreational area located very close to Ogden and the nearby areas. Camping, boating, water-skiing and personal watercraft use, as well as trout, bass, crappie and wall-eyed pike fishing are popular activities in the recreational area.
