Jordanelle Reservoir is fed and drained primarily by the Provo River, and is impounded by the Jordanelle Dam, an Earthen dam. The construction of the dam resulted in the reroutings of U.S. Route 40 and U.S. Route 189 over the summit of nearby mountains and the submergence of the towns of Keetley and Hailstone.
Jordanelle State Park opened on June 29, 1995. Construction of the dam was challenged by several groups. Conservationists wanted to maintain the natural state of the Provo River. Because of this, a large area at the foot of the dam was converted into an artificial wetland. Other groups were concerned that the site was geologically flawed, citing the catastrophic failure of the Teton Dam in Idaho in 1976. Mining interests in nearby Park City were also concerned, fearing that the reservoir would flood sections of the Ontario Mine.
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. Dam National ID Number: UT82912
