Released On: September 30, 2010
PNK Constructors, LLC, of Coalville, Utah, was awarded the contract on September 20.
The existing dam crest will be raised by 4-feet, and construct a 19.5 foot single travel lane across the crest to accommodate semi-trailer trucks and other oversized vehicles. By raising height of the dam, Reclamation will address operational vulnerabilities related to motorized traffic traveling across the top of the dam.
Construction will begin in April 2011, and is estimated to be completed by June 2011. During construction, the dam crest will be closed to traffic, requiring travelers to use Cow Creek, Blacks Creek, or Pine roads to access Anderson Ranch Reservoir and the South Fork of the Boise River below the dam.
"When possible, Reclamation will allow large trucks an opportunity to cross the dam," said Jerrold Gregg, Snake River Area Manager. "We ask that the public exercise caution around the area and obey traffic and detour signs until the project is completed."
Anderson Ranch Dam was constructed by Reclamation in 1950 as part of the Arrowrock Division of the Boise Project. It is a multipurpose facility that provides for irrigation, flood control, hydropower, and recreation.
