U.S. awards $5.5 million rehab contract for 4.95-MW Deer Creek Dam

The Bureau of Reclamation awarded a $5.5 million seismic modification contract to PNK Constructors LLC for 4.95-MW Deer Creek Dam in Utah.

PNK, of Coalville, Utah, is to perform the final stage of a multi-phase project that includes improvements to the spillway control structure and raising the dam crest, BuRec said. (HNN 7/10/07) The work is scheduled for completion in late fall or early winter 2008, according to BuRec and Provo River Water Users Association, which operates and maintains the dam under contract to BuRec.

BuRec launched the multi-phase project to modify the 235-foot-tall, 1,300-foot-long zoned earthfill dam and spillway structure in 2003 to enable it to withstand a large seismic event.

Deer Creek Dam, the main feature of the Provo River project, was completed in 1941. The dam stores water for municipal and irrigation needs of Utah and Salt Lake counties.

Deer Creek Dam improvements are being conducted as part of BuRec’s Safety of Dams Program, which involves regular inspections of dams throughout 17 Western states to identify and correct deficiencies and improve seismic performance.
