Lake Mead drops to lowest level since first fill #ColoradoRiver

From the Associated Pres via the Cache Valley Daily:

The projected lake level of about 1,080 feet above sea level will be below the nearly 1,082 feet recorded in November 2010, and below the 1,083 feet measured in April 1956 during another sustained drought. But U.S. Bureau of Reclamation regional chief Terry Fulp said water obligations will be met at least through next year without a key shortage declaration. The result will be full deliveries to cities, states, farms and Indian tribes in an area home to some 40 million people and the cities of Las Vegas, Phoenix and Los Angeles.

“We will meet our water orders this year and we are not projecting a shortage condition in 2015,” Fulp said in a statement. “We continue to closely monitor the projections of declining lake levels and are working with stakeholders throughout the Lower Basin to keep as much water in Lake Mead as we can through various storage and conservation efforts.”

The lake on Tuesday was just under 1,082 feet above sea level, and the reservoir was about 39 percent full, said Rose Davis, a bureau spokeswoman in Boulder City, Nevada. The dropping level since the reservoir was last full in 1998, at just under 1,296 feet above sea level, has left as much as 130 feet of distinctive white mineral “bathtub ring” on hard rock surfaces surrounding the lake. Davis said the bureau expects a slight increase in water level to about 1,083 feet by Jan. 1, 2015.

“We projected this was coming.” Davis said. “We are basically where we expected to be, given the in dry winters in 2012 and 2013,”[…]

Las Vegas, with more than 2 million residents and some 40 million tourists a year, is almost completely dependent on Lake Mead for drinking water.

Federal and state water officials have negotiated plans for a shortage declaration triggering delivery cuts to Nevada and Arizona if annual projections for the Lake Mead water level drop below a 1,075 foot elevation. That projection is based on data currently being compiled by the Bureau of Reclamation.

Davis said the 1,075 foot trigger point is not expected this year or next. But last year, after back-to-back driest years in a century, federal water managers gave Arizona and Nevada a 50-50 chance of having water deliveries cut in 2016.

California, Colorado, Utah, New Mexico and Wyoming wouldn’t see direct cuts in their share of river water, but officials have acknowledged there would be ripple effects.
