Narration

Geology

The design data for Jordanelle Dam was reviewed by three independent panels of internationally recognized earth science authorities who concluded that a dam the size of Jordanelle could be safely constructed at the selected site. In addition, the combined United States and Utah Congressional Delegation conducted an in-depth investigation and declared Jordanelle Dam to be geologically sound.

The dam is designed to withstand an earthquake of Richter scale magnitude 7.5 on the Wasatch Fault (19 miles west of the damsite), and magnitude 6.5 for a local random earthquake directly below the dam.
