Western States Face First Federal Water Cuts (apnews.com) 204

phalse phace shares a report from The Associated Press: U.S. officials on Monday declared the first-ever water shortage from a river that serves 40 million people in the West, triggering cuts to some Arizona farmers next year amid a gripping drought. Water levels at the largest reservoir on the Colorado River -- Lake Mead -- have fallen to record lows, underscoring the acute water challenges for a region facing a growing population and a drought that is being worsened by hotter, drier weather brought on by climate change. Federal officials said Monday's declaration makes clear that conditions have intensified faster than scientists predicted in 2019, when some states in the Colorado River basin agreed to give up shares of water to maintain levels at Lake Mead.

Water levels at Lake Mead and Lake Powell, the river's two largest reservoirs, have been falling for years and faster than experts predicted. Scorching temperatures and less melting snow in the spring have reduced the amount of water flowing from the Rocky Mountains, where the river originates before it snakes 1,450 miles (2,334 kilometers) southwest and into the Gulf of California. Water stored in Lake Mead and Lake Powell is divvied up through legal agreements among the seven Colorado River basin states, the federal government, Mexico and others. The agreements determine how much water each gets, when cuts are triggered and the order in which the parties have to sacrifice some of their supply. Under a 2019 drought contingency plan, Arizona, Nevada, California and Mexico agreed to give up shares of their water to maintain water levels at Lake Mead. The voluntary measures weren't enough to prevent the shortage declaration.

    'Federal officials said Monday's declaration makes clear that conditions have intensified faster than scientists predicted'

    It's a sad world where such an admission is problematic, but given the propensity of anti-vaxxers to spot anything to prove their scepticism, we have an issue:

    How can we train journalists, press release writers and the public to realise that the statement: 'the scientists say' is merely their best guess / belief, and the fact they may be wrong isn't really significant?

          It is time to desalinate in a major way.

          No it isn't. Desalination is the dumbest possible solution to the problem. A far better solution is to stop growing subsidized rice in the desert.

          It costs $2000 to desalinate an acre-foot of water.

          Water from Lake Mead is provided to farmers growing subsidized crops for $70 per acre-foot.

          Paying $2000 for something you give away at $70 to someone who dumps it on the ground is idiotic.

                I am not sure why you say that this map shows that the water shortage "wasn't caused by sucking up too much water for agriculture." I would have thought if anything it shows the opposite; the epicenter is shown as agriculture-rich California's central valley, with a finger heading east across southern Nevada (a place where the population density is near zero, except for Las Vegas, which is its own problem) and then into Utah, a place where 80% of the diverted water goes to irrigation.

                  The map shows drought, not water shortage, yes, hence the title drought map. However, water shortages can be caused by drought and a drought of magnitude shown on the map will cause water shortages. The "finger" you see on the map is not caused by water usage. It is caused by drought.

                  They don't measure the drought by how much people are using. They measure it with rain gauges and soil moisture content. Sucking up underground aquifers won't cause surface moisture content to change unless the underground aqui

                    Well, the soil moisture content is affected by agriculture. The water table has dropped so far that some wells have shut down. That affects the soil moisture everywhere plants have deep roots.

                    OTOH, the drought is, indeed, caused mainly by lack of rain. But the lack of snow-pack is probably more significant, as that's what determines the runoff during the dry season. And THAT is at least half due to the increased temperatures, not just to the lack of snow-fall. Snow is expected to stay in the high mount

                • 20 years ago there was plenty of water for both the people and the agriculture. Population growth really hasn't been that high. Across the entire country I think we've added about 20 or 30 million people since then. That's not enough to account for water shortages. Furthermore meteorologists are saying we're in a drought. That literally means there's less water to go around. The reason the GP linked to a drought map is because that's the evidence that we're in a drought.

California has asked residents to cut back by 15% - to free up 1.5% of total water use. Should be obvious where we can conserve. Growing crops like alfalfa is just a giant waste. We could make better use of what we have.

                I think you might rephrase your question, because there is no set right amount of water. Different crops use different amounts of water. And that's an important part of how food works.

                Pasture (clover, rye, bermuda and other grasses), 4.92 acre feet per acre

                Almonds and pistachios, 4.49 acre feet per acre

                Citrus and subtropical fruits (grapefruit, lemons, oranges, dates, avocados, olives, jojoba), 4.23 acre feet per acre

                Sugar beets, 3.89 acre feet per acre

                • Weird that rice isn't on your list.

                • Almond growing used to be small but it really took off in the last few decades because the price is very high. It's a luxury food. There was a tiny almond orchard across the street from me growing up, and really it wasn't irrigated much at all, but it also wasn't producing almonds in high numbers either. So I think the water use is really to get the production up.

                  • Almonds have taken off in a big way because of almond milk's popularity.
                    Alfalfa is being grown in CA and being shipped to Saudi Arabia, because it's cheaper to use CA water AND ship it to Saudi Arabia than it is to use Saudi Arabian water.

                  • Alfalfa is big. It's a simplistic crop; easy to grow, easy to harvest, easy to ship. It's for cows so it doesn't matter much if the harvested product doesn't meet grocery store visual standards or not.

                    I see a lot of Vegans are claiming that we need to go vegan because cows suck up a lot of water.

              If for instance more expensive and lower yield farming necessitates a large drop in land prices, that could mean in a free market that mass banruptcies and perhaps bank failures would be necessary first before farming could get more water efficient.

            Paying $2000 for something you give away at $70 to someone who dumps it on the ground is idiotic.

            It's actually more like $900 to desalinate an acre-foot of water. The $2000 figure is probably a little outdated. At the residential prices from the water company where I live, it would be $2631.02 for an acre foot of water at their lowest water rate. Of course, then there would be a corresponding sewer charge of an additional 3,929.11. That's not for desalinated water, just regular reservoir water. The prices go up the more you use, so if you were using more than 15,000 cubic feet (there are 43560 cubic feet in an acre-foot, so you would be) it would be $3162.46 for the water and the sewer charge would be the same. If you were to buy the water in gallon jugs from my local supermarket, an acre-foot would be about $260,000. Delivered by a water truck it would be around $13,577 for an acre-foot of water.

            All of this seems to suggest that, for the regular consumer, the cost of desalination would be marginal compared to what they're already paying for water. It seems really high when you look at the prices farmers pay because, as you say, that's obviously heavily subsidized. It does look like we may need to re-examine the farming model being used. Specifically the use of cheap land as farmland. It makes sense as long as water is cheap, but if you have to make the water cheap, then the real price of farming there is obviously being hidden. If we have no choice though, because we developed all of the other land, pushing farming to the fringes, then we need to make the water cheap in order to have food.

          • Yeah there's some parts of Arizona possibly New Mexico that have farms that are kind of silly. Arts of California have extremely good land that's only limited by the amount of water. Think about how much California or even Arizona's agriculture is worth and realize that that's all food people are eating. Now ask yourself what would happen to the price of food if all that was not in the market.

            Yeah we waste a lot of food but not that much. Moreover it's stabilizes our food supply so they're on shortages.

              Many have pointed out that the almonds are a net loss.

              More structurally, Californian agriculture is dependent in part on depletion of aquifers. And some of them are nearly fully depleted now, and are not being refilled at any useful rate. So frankly the water problem in California is much worse than it appears. I presume this to be true in much of the world, let alone the nation, but I know it to be true in California.

And I think once the land "drops" the sponge is compressed and will not hold as much ground water in the future. The article I cit
            • The food grown in California and Arizona can be grown in the rest of the U.S. and rest of the world. So in a great many cases it would be better to transfer crops and livestock elsewhere than to massively subsidize water costs for California and Arizona farmers.

                That's not really true. All the good farm land is currently being used as farm land...not just in California, but in the country, and in most of the world. Most of California is really an arid area rather than a desert, but much of the country really IS a desert. The Sierra-Nevadas create a strong rain shadow. As you go farther North, the growing season shortens, not just because of temperature, but also because of day length. Which is most important varies, of course. Plants with a short growing sea

              Now, think about all of those "flyover" states and realize that east of the Continental Divide that almost all of that is farmland and you'll realize just how little (relatively speaking) California and Arizona actually contribute to the gross food production in the US. The only reason California seems to produce a large percentage of food to the US is that a lot of that "flyover" farmland is soybeans and feed corn. If all agriculture west of the Continental Divide stopped the farmers in the interior would shift over to human food from soybeans and the US would still be just fine. Food would be more expensive, to be sure - maybe 10% - but we'd be fine.

    Golf courses use about 130,000 gallons per day per course. They should be among the first to curtail their water usage during drought conditions.

    Lawn irrigation a close second, which is already a thing in some places.

    I understand that it's convenient (especially for California) to blame climate change for the water woes of the West, but the problem has existed for FAR longer than most (especially California) would care to believe. Water Education Colorado [1] has a good article about the 2019 Colorado River Drought Contingency Plan, which includes this "fun" fact (bolding by me):

    As Eric Kuhn and John Fleck write in their new book, “Science Be Dammed: How Ignoring Inconvenient Science Drained the Colorado River,” even during compact negotiations in the 1920s, records showed the river’s annual flows were lower than the total 17.5 million acre-feet allocated to the seven states and Mexico. In fact, three different studies during the 1920s estimated natural river flows at Lee Ferry at between 14.3 million acre-feet and 16.1 million acre-feet. Planners chose to ignore that information, Fleck says, and with it, they ignored convincing evidence showing the basin regularly experienced long periods of drought.

    In other words, the original compact allocated about 110-120% of the estimated natural river flows at the time... in the 1920s!

    Now add in the fact that "in the lower basin, California, Nevada and Arizona have long overused their share of the river," [1] and "for many years, California has depended on surplus water [from Nevada's and Arizona's apportionment] to meet its water needs—and to supplement its basic apportionment of 4.4 million acre-feet per year" [2; from 2001] and you start to question, what exactly did we expect to happen?!

    The water allocated exceeded the river flow FROM THE BEGINNING IN THE 1920s! The Lower Basin has overused their water for DECADES! And California has lived on (literally) borrowed water for DECADES! Anybody working with water in the West who didn't foresee what is currently transpiring is blind, incompetent, corrupt... or all three. And that's why they're all pointing the finger at the convenient villain of climate change instead of themselves.

    • If you're an official in the water sector, what do you do? The most you can do is whinge at politicians, whose motivation is to keep the show on the road for their constituents. Is a politician going to propose the necessary cuts when there's, very visibly, a whole dam full of water?

      It would be nice to identify individuals here to blame. Sadly I don't think we can do so; all we can do is try to make sure the rational changes are implemented going forward.

    Manage growth or resource constraints will manage it for you.

  • The arguments surrounding this particular issue are amusing... everyone has a point of view but they are all having the wrong argument.

    This issue is macro not micro. Decisions at a state level mean nothing, won't mitigate the problem, and the problem will only get worse even if carbon emissions are cut to zero.

    There will be less water in a lot of areas.

    The macro solution is to move agriculture out of those states and use the vacant land to gather solar energy. This way the farmers still get an income from t

    • nonsense, the problem is only of needing water to keep farming in the dessert. Perfect application for solar desalinization by new low cost methods.

      it's all an engineering problem, nothing more.

      • You might be able to divert some of the water that currently goes to Cal coast from the colorado by desal methods, but you are not going to be able to desal ocean water and pump it back to AZ/NV at any sort of reasonable cost. Even central valley cal would cost a ton to provide desal water to. Irrigation water is and must be cheap cheap cheap. You may have plenty of sun in AZ/NV to desal salty water, if you only had a salty water source.
    • You should seek to understand the problem before presenting a solution and saying that everyone else is wrong.

    We need to start building nuclear fission powered desalination plants. We needed to start decades ago. The problem will only get worse until people wise up to the solution and act on it.

    We will build more nuclear power plants in the USA because we ran out of options. It's that or energy poverty, water shortages, food shortages, and generally quality of life taking a dive. That is assuming you survive.

    We need to build things. This is a supply problem, not a demand problem.

    • The desalinization plant doesn't even need to be fission powered. We have all those spent nuclear fuel rods that are generating a lot of heat due to isotope decay.

      If you put the focus on producing just usable water and not electricity the whole game changes. By setting up the right conditions you don't need a high heat differential, you can boil water at room temperature by reducing the air pressure on it. The OTEC [wikipedia.org] system only needs about 20 C to produce fresh water and electricity.

      • The desalinization plant doesn't even need to be fission powered.

        Yes, they do. Anything else and California will keep having energy shortages, pollution problems, or wildfires which I guess is just repeating the issue of air pollution.

        We have all those spent nuclear fuel rods that are generating a lot of heat due to isotope decay.

        Those "spent" fuel rods contain a lot of useful fuel yet, and many useful isotopes. We'd be far better of reprocessing the fuel.

        Reprocess the spent fuel and concentrate the "waste" isotopes and you could get higher temperatures and thus greater efficiencies.

        If you reprocess the fuels to get the isotopes useful for radio-thermal power then you'd be better off putting that into space exploration, military applications, medical devices, and so much more. Using that fo

    In water rights law, the oldest claims are the strongest claims

    If I have a claim for 100,000 acre feet of water per year that dates from 1850
    and you have a water rights claim for 10,000 acre feet of water from 1949

    I get my water before you get yours.

    Federal water managers will cut off water to farmers before they cut off water to cities. However, the majority of time, the farmers have the oldest water rights claims. When it goes to court, the farmers win, and the cities lose.

    This results in a situation where the cities have to buy out the claims of the farmers.
