For Release: June 20, 2007

The Bureau of Reclamation today released a Final Environmental Assessment (EA) for the Drop 2 Storage Reservoir Project. Authorized by Public Law 109-432 of December 20, 2006, the reservoir would be constructed along the All American Canal (AAC) about 25 miles west of Yuma, Arizona.

The project will provide additional regulating capacity to maximize within the United States the beneficial use of Colorado River water released from Parker Dam. It includes a storage reservoir with a capacity of 8,000 acre-feet; an inlet structure from the AAC to the reservoir; and an outlet structure that connects the reservoir back to the AAC. The reservoir would be used to capture Colorado River water that, because of inclement weather, higher than normal flow periods, or other factors, exceeds user demand.

The proposed reservoir could save on average approximately 70,000 acre-feet of Colorado River water per year, ultimately reducing the amount of water released from Lake Mead.

Construction activities are scheduled to begin in 2008.

The draft EA is available on-line at: in the Environmental Documents section, or can be requested from Mr. Ed Virden (Environmental Group Manager) at 928-343-8268 or by e-mail to
