The Bureau of Reclamation awarded a $98.3 million construction contract for an 8,000-acre-foot reservoir and conveyance system at California’s All American Canal Drop Structure No. 2.
BuRec awarded the contract to a joint venture formed by Ames Construction Inc. of Phoenix, Ariz., and Coffman Specialties Inc. of San Diego, Calif., from proposals submitted in response to a solicitation. (HNN 6/9/08)
The Drop 2 Storage Reservoir project would provide space to conserve flows from Imperial Dam that are not captured in the lower Colorado River system. Capture of the water could reduce releases from 2,078-MW Hoover Dam and annually save 72,000 acre-feet of Colorado River water, BuRec said.
The agency anticipates work on the project will be completed by the end of August 2010. The project is located in Imperial County, Calif., 30 miles east of El Centro and 25 miles west of Yuma, Ariz.
Interior Secretary Dirk Kempthorne announced the award Aug. 21. He said the project will help ensure efficient and effective water management, benefiting water users by allowing them to capture Colorado River water that otherwise would be lost.
The All American Canal System, in southeastern California, is part of the Boulder Canyon project. It consists of Imperial Dam and desilting works, the 80-mile All American Canal, and the 123-mile Coachella Canal. Imperial Irrigation District built hydro plants totaling 72.4 MW on the canal system at Pilot Knob and Drop Nos. 2, 3, and 4.
