Gracon LLC of Loveland, Colo., has received a $1.4 million contract from the U.S. Department of Interior’s Bureau of Reclamation for civil work at Lemon Dam on the Florida River near Durango.
Lemon Dam is a zoned earthfill structure with a structural height of 284 feet and a crest length of 1,360 feet. It was completed in 1963. Lemon Dam is the principal feature of the Florida Project, part of the Colorado River Storage Project, and impounds water for flood control and irrigation water storage.
The work will involve fabricating and installing a steel intake bulkhead gate and refurbishing four trashracks and high-pressure slide gates. The bulkhead gate will seal the intake structure to provide a dry environment for working on the slide gates. The trashracks prevent unwanted debris from entering the intake structure and protect the high-pressure slide gates that regulate flows through the dam.
Off=site fabrication for the bulkhead gate and other preparatory work is to begin this month. On-site work at Lemon Dam will begin in late October and be completed in January 2017.
Reclamation has facilities in the 17 western states that generate electricity and provide flood control, recreation, and fish and wildlife benefits.
