    It's the golf courses. The biggest waste of space and resources known to man.
    Cut off all the irrigation to all the golf courses in the south west, especially in Utah and Arizona, and Lake Mead will fill up again in a few short years.

    Golf courses are a huge consumer of water but your claim is grossly exaggerated.

    It would be easy enough to move where there's more water. The difficult thing would be moving thousands of acres of trees and vines where there's more water.

    In SoCal a full 25% of the water use is indoor urban use.

    My post about the incolet is serious. No water is used for this toilet nor the resulting sewerage since it burns the waste to clean ash. It uses very little energy and can be operated with NG or electricity. There is no reason to tap into sea water which would require extensive development time and still be costly at market (not to mention the environmental issues). Just switch out the toilets.

    Vegas is doing everything possible to save water but Meade is still expected to drop 20 feet this year. It is a losing battle.

    "

    Spurred by conservation efforts in Southern Nevada and elsewhere, per-capita water use on the Colorado River declined significantly while the West boomed over the past two decades.

    A new report by the Pacific Institute shows per capita use fell by an average of at least 1 percent a year from 1990 to 2008, a period that saw the population in the Colorado River basin swell by more than 10 million people.

    Some of the most impressive water-efficiency improvements came in the Las Vegas Valley, where individuals cut their use by roughly one-third while the population almost tripled.

    "Southern Nevada has done very well. Their use has declined dramatically," said researcher Michael Cohen, who authored the report for the Oakland, Calif.-based environmental think tank.

    "In 1990, the average valley resident consumed 347 gallons of water per day. By 2008, the last year included in the report, that figure had dropped to 248 gallons per day thanks in large part to several communitywide restrictions and incentives aimed at saving water.

    As the valley's population boomed, the Southern Nevada Water Authority and its member utilities responded with assigned watering days and a ban on front lawns for new homes. They started paying residents and businesses to rip out thirsty grass and make other efficiency improvements.

    I wonder just where they drew the line between northern and southern? In this area, the major impact of a drought is on agriculture, and any impact on agriculture is going to raise the cost of food for the whole country. \

    Every golf course uses up to one million gallons a day. Southern California 600, Utah 117, Arizona 322, and Nevada 98.
    Well over ONE BILLION GALLONS A DAY!
    You don't think that would make a huge impact on the Colorado river?

    The Colorado River, which cut the Grand Canyon, and supplies Lake Mead, hasn't reached the sea since the 1950's as all the water is used up.
    Don't work out, work in.

    Never eat anything that's served in a bucket.

    Grow new ones. There probably aren't many trees and vines in the desert anyway.

    I'm not sure just where you got those figures, but let's assume for now they're correct.
    Flows of the Colorado river are in the order of 2,000 to 20,000 cubic feet per second. Let's take an average of 10,000 cfs to make the math simple. The next question is, just how much is a cubic foot?

    Turns out to be 7.48 gallons.

    So, 10,000 x 7.48 = 74,800 gallons per second on average.

    60 x 60 x 24 x 74,800 = 6,462,720,000.

    If your billion gallons a day figure is accurate, then, a little less than 1/6 of the water is being used for golf courses. That is assuming, of course, that those golf courses aren't using recycled water.

    So, yes, given those conditions, the proportion of the water used for that purpose is significant.
