Shoshone Project - Administration

Administration

The project is administered in four divisions:

• The Garland Division, with 35,863 acres (14,513 ha) of irrigated land, receives water diverted into the Garland Canal by the Corbett Diversion Dam on the Shoshone, 16 miles (26 km) downstream from Buffalo Bill Dam. The 18 miles (29 km) canal has a capacity of 1,000 cubic feet per second (28 m3/s). The Garland Division is administered by the Shoshone Irrigation District, directed by local water users.
• The Heart Mountain Division, with 31,120 acres (12,590 ha) receives seasonal output from the Heart Mountain Powerplant, which discharges into an inverted siphon crossing the Shoshone River. The 26 miles (42 km) Heart Mountain Canal transports the water to users at a rate of 915 cubic feet per second (25.9 m3/s). Portions of the Heart Mountain Canal were built with labor provided by the Civilian Conservation Corps from camp BR-72. Japanese American internees from the Heart Mountain Relocation Center worked on the canal in from 1942 until May 1944. Work was finally completed in 1947.
• The Frannie Division, with 14,600 acres (5,900 ha) receives water from the Garland Canal through a branch canal, the Frannie Canal, which is 44 miles (71 km) long and carries 550 cubic feet per second (16 m3/s).
• The Willwood Division, with 11,530 acres (4,670 ha) receives water from the Willwood Diversion dam on the Shoshone, 8 miles (13 km) downstream from the Corbett Diversion Dam. The Willwood Canal extends for 28 miles (45 km) and can deliver water at 320 cubic feet per second (9.1 m3/s).
