(1.2 Million acre feet of water added to Lake Mead)....It has raised the reservoir 16 feet.

Thanks in part to the efforts of the Imperial Irrgation District and Imperial Valley growers, Colorado River water users in California together have voluntarily conserved more than 1.2 million acre-feet of water in just 2 years. By working together, the conserved water has been left in Lake Mead, the nation's largest reservoir, to help stabilize and protect critical reservoir elevations after more than 2 decades of historic drought conditions, according to figures released this week by the Colorado River Board of California. The results were reported during CRB's meeting at this year's Colorado River Water Users Association's annual conference.
