Crystal Dam

Unlike its upstream companions, excess water spills over the top of the dam through a notched-out, ungated spillway that can create a 227-foot (69 m) waterfall in times of overflow.

Under normal conditions the river flows through an 11.5 feet (3.5 m) diameter penstock to the 28 MW turbine.

Concrete work resumed in April 1976, with final completion of the dam structure on August 30, 1976.

Filling operations in the reservoir began on March 14, 1977, permanently blocking the diversion tunnel on April 12.

The powerplant was not completed until 1978, the victim of a fire in the contractor's warehouse that destroyed many electrical components intended for the plant.

A Francis-type turbine removed in 1989 from Crystal Dam Powerplant is currently displayed at Glen Canyon Dam .
