U.S. plans solicitation for new California reservoir

The Bureau of Reclamation is preparing a solicitation to build an 8,000-acre-foot reservoir and 1,800-cfs conveyance system to provide additional storage of water at All American Canal Drop Structure No. 2 in Imperial County, Calif.

BuRec’s Lower Colorado Region issued a solicitation notice saying it could issue a solicitation for the Lower Colorado River Drop 2 Storage Reservoir project on April 21. Responses would be due June 6.

BuRec said the project would provide space needed to conserve a portion of flows that pass downstream from Imperial Dam and are not captured in the lower Colorado River system. Capture of the water ultimately would reduce releases from 2,078-MW Hoover Dam and annually save 72,000 acre-feet of Colorado River water, BuRec said.

The agency estimated the cost of the construction project would exceed $100 million. It anticipates work would begin this September and end in October 2010.

A site visit is planned for May 6. BuRec suggested prospective bidders make arrangements to attend by contacting Marge Schafer, (1) 702-293-8394; E-mail: mschafer@lc.usbr.gov.

Solicitation No. 08SP308114 is to be available on the Federal Business Opportunities Internet site, www.fbo.gov, about April 21. Bidders must register in the federal government’s Central Contractor Registration system, www.ccr.gov.

The All American Canal System, in the southeastern corner of 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 hydroelectric plants totaling 72.4 MW on the canal system at Pilot Knob and Drop Nos. 2, 3, and 4.

Imperial Hydro LLC, an affiliate of Symbiotics LLC of Rigby, Idaho, has applied for a preliminary permit to study the feasibility of developing a 2.1-MW Imperial Diversion Dam hydroelectric project (No. 12947) at Imperial Dam. The application, filed in August 2007, is pending with the Federal Energy Regulatory Commission. BuRec maintains Imperial Dam is not under FERC jurisdiction, meaning approval for private development must come from BuRec.
