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. Its shape is similar to that of an airliner, or a bird.
Pineview Dam is located at the eastern end of Ogden Canyon at the confluence of the north, south and center forks of the Ogden River. 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.
The Ogden River 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 30,000 acre foot (37,000,000 m3) 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 44,175 acre foot (54,489,000 m3) capacity. The later Weber Basin Project increased the height of the dam to 137 ft (41.8 m), enlarging the capacity to 110,150 acre feet (135,870,000 m3). 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).
