BILLINGS, Mont. -- The Bureau of Reclamation has awarded a $7.8 million contract to Moltz Constructors, Inc., of Cody, Wyo., to complete modifications at Guernsey Dam.

Guernsey Dam is scheduled to undergo modifications in relation to work being performed at Glendo Dam, located 25 miles upstream from Guernsey. The modifications are in response to Reclamation's safety of dams recommendations and will ensure structural integrity of Glendo and Guernsey Dams should a large flood event occur.

Modifications include redesigning the south spillway, installing a filter blanket type drain next to the north spillway and adding a taller parapet wall to the top of the dam. Work is scheduled to be complete in spring 2014.

"Reclamation is pleased to award this contract to a local Wyoming business," said Great Plains Regional Director Michael J. Ryan. "The contract ensures Reclamation facilities continue delivering water and power safely well into the future."

Guernsey Dam is located in a rocky canyon two miles upstream from Guernsey, Wyo. The dam is a diaphragm-type embankment of sluiced clay, sand and gravel, with a structural height of 135 feet. Guernsey Powerplant has two units generating more than 14 gigawatt-hours annually. Power is transmitted to towns and industries down the valley over project and other interconnected transmission system lines.
