The Palisades Dam

Posted on Posted in Dams

Palisades Dam is an earth-fill dam on the Snake River in Bonneville County in the U.S. state of Idaho. The dam was completed in 1957 and provides irrigation water, flood control, and recreation; it features a four-turbine hydroelectric power plant. The dam can potentially generate 176.5 MW of electricity. The resulting water impoundment, Palisades Reservoir, has a storage capacity of 1.2 million acre-feet.

The Palisades Project supplements the storage and power generation facilities of the earlier Minidoka and Michaud Flats projects, which serve irrigation interest in Idaho on the Snake River Plain, saving about 1,350,000 acre feet through the winter for use in the growing season. With 13,571,000 cubic yards of material, the dam was the largest in the USBR system at the time of its construction.
