It is no surprise, of course, that the western United States is dry. The entire history of the West can be told (and has been, in great books like Cadillac Desert [Reisner] and Rivers of Empire [Worster] and The Great Thirst [Hundley]) in large part through the story of the hydrology of the West, the role of the federal and state governments in developing water infrastructure, the evidence of droughts and floods on the land, and the politics of water allocations and use.

But the story of water in the West is also being told, every day, in the growing crisis facing communities, watersheds, ecosystems, and economies. This isn’t a crisis of for tomorrow. It is a crisis today. What is, perhaps, a surprise, is that it has taken this long for the entire crazy quilt of western water management and use to finally unravel. But it is now unraveling.

The old adage of the blind men describing an elephant based on their experience touching different parts of it applies to western water. In the past few years, we’ve seen bits and pieces of the puzzle: a well, and then two wells, and then a town goes dry. A farmer has to shift from water-intensive crops to something else, or let land go fallow. Vast man-made reservoirs start to go dry. Groundwater levels plummet, yet the response is to try to drill new and deeper wells and pump harder, or build another dam, or move water from an ever-more-distant river basin. Competition between industry and farming increases. And politicians run back to old, tired, half-solutions rather than face up to the fact that we live in a changed and changing world.

Here are a few pieces of the puzzle that we had better start to put together into a coherent picture if we hope to change our direction.

  • In January 2012, the Texas town of Spicewood Beach ran out of water. Then Magdalena, New Mexico ran out. More recently, Barnhart, Texas. Now Texas publishes a list of towns either out or running out of freshwater. In some parts of Texas, demands for water for fracking are now competing directly with municipal demands.
  • Because of a severe, multi-year drought (described as “the worst 14-year drought period in the last hundred years”) and excessive water demands, the US Bureau of Reclamation, this week, announced it will cut water released from Lake Powell on the Colorado River to the lowest level since the massive reservoir was filled in the 1960s. Water levels in Lake Mead have already dropped more than 100 feet since the current drought began in 2000, but even in an average year, there is simply more demand than supply.
  • Las Vegas is so desperate for new supplies they have proposed a series of massive and controversial ideas, including: a $15+ billion pipeline to tap into groundwater aquifers in other parts of the state, diverting the Missouri River to the west, and building desalination plants in Southern California or Mexico so they can take a bigger share of the Colorado.
  • Governor Jerry Brown is pushing a $25+ billion water tunnel project to try to improve water quality and reliability for southern California farmers and cities and improve the deteriorating ecosystems of the Sacramento-San Joaquin Delta, with no guarantees that it will do any of those things at a price users are willing and able to pay.
  • San Luis Reservoir in California, which serves the Silicon Valley and other urban users, has fallen to 17 percent because of severe drought, making business, communities, and water managers nervous. Other major California reservoirs are also far below average, though massive deliveries of water continue on the assumption that next year will be wet.
  • Praying for rain has become an official water strategy for some politicians in Texas, Georgia, Florida, Oklahoma, and elsewhere.
  • Another popular water strategy seems to be to sue your neighboring state. Here are some examples: Texas v. Oklahoma and Kansas v. Nebraska and Colorado, and outside of the west, Florida v. Georgia (and Alabama too).
  • Groundwater is disappearing in California; the Great Plains; Texas (tables in this report (pdf) show continuous and often massive declines in almost all Texas groundwater systems); and elsewhere in the West, because our laws and policies ignore the fact that surface and groundwater are connected. Contributing the problem, water managers and legislators typically put no restrictions on groundwater pumping, leading to inevitable, and inexorable, groundwater declines.
  • In the Lower Tule Irrigation District in California, demand for water has grown over the past two decades from 250,000 AF/year to 450,000 AF/year, much of it supplied by overpumping groundwater. In parts of the district, the average depth to groundwater in 1983 was 50 feet. In 2003, groundwater levels had declined to 75 feet. Today it is 125 feet, and some wells 300 feet deep are going dry.  In April 2013, John Roeloffs, a farmer and member of the Lower Tule Irrigation District Board, noted “Some guys are drilling wells 800 feet deep.”
  • There is more and more and more evidence of declining snowpack in the western US as the climate warms.

These are just a few recent examples of the growing water-related dislocations in the western US. Writ large, the entire region is at risk. As long as we fail to address the real problems, real solutions will never be applied.

First, we must acknowledge that we’ve reached peak water in the American west. We have promised more water to users than nature provides. Until demand and supply are brought back into balance, groundwater levels will continue to drop and our rivers will continue to run dry, destroying natural ecosystems. Second, we must acknowledge that there are limits to new supply and that we must turn to the demand side of the problem. This means figuring out how to use water more efficiently and productively, and thinking about moving some water-intensive activities and products to more water-abundant regions. Maybe it is time to grow less rice, alfalfa, cotton, and pasture with flood irrigation. It is past time to retire the green lawn as an acceptable landscape option in arid climates. All toilets and washing machines should be water- and energy-efficient. Finally we have to stop assuming that the water available for future use is the same as in the past. Climate change ensures that it won’t be, but until politicians start to heed the warnings of climate scientists and the on-the-ground evidence of the current water situation, our water problems in the west, and elsewhere, will worsen.

    Is there a simpler solution than declaring a groundwater bankruptcy, in which all water-rights holders are awarded acre-inches on the acre-foot, to be reviewed periodically to match further changes in precipitation ?

      Interesting idea. Part of the problem is there is little groundwater management (or little consistent and effective management), so there are few places where a mechanism to impose such a solution are in place. But overall, yes, we will have to start limiting withdrawals to what is called the “safe yield” — the amount that can be renewable pumped and permitting recharge to occur in wetter years.

    Hi Peter,

    Has the privatisation of the water industry contributed to the problems of water supply in the American West?

    If so, are these companies still making a profit?

    Thank you.

      Heather, not particularly. There has been very little privatization — just a few small municipalities. The biggest challenges for water in the West related to uncontrolled or managed groundwater extraction, large-scale inefficient agricultural water use, and long-term drought and shortage.

    Just a brief note; maybe I’ll have a thought later about this notion of “peak” water.

    I saw no mention in this piece of water shortage or trouble in my home state of Arizona.

    But how can that be? Arizona is in drought, and has been for a while. It’s reeeely hot here. So why no water problems?

    Planning, grasshopper. Planning and preparation. We had some very smart folks who saw what our needs might be and planned for them.

    • #11 Peter Gleick
      August 20, 2013

      I don’t think you can really say that Arizona has avoided water problems — I may not have included any examples, but still….
      Your general point, however, is certainly right: planning, planning, planning, and preparation!

    Jack, tell us about the Rim aquifers that Flagstaff is pumping so dry that towns like Camp Verde are seeing their springs running dry. And last I heard, CAP or no the water table in central Arizona is still dropping.

    A minor correction: Magdalena’s water problem is due in large part to a broken well, not to a drop in water level per se (there’s still a problem there, but it’s not the one that’s causing the town to import water from Socorro.) Actually, Magdalena is in relatively good shape since their aquafier is not shared with cities (Magdalena is small and if anything shrinking) or irrigated agriculture.

    For those who aren’t familiar with the Lower Colorado: USBR isn’t reducing water deliveries in 2014, just moving less water between Powell and Mead because Powell is lower than Mead as a percent of storage after 2 dry years in a row. Note that Powell is still higher than in 2005. As of last week storage equaled 50%, or about 4 times the annual release planned for Powell, and under the most probable inflow scenarios (which assume below average inflow) even 2015 will still see normal water deliveries.

    From the USBR press release linked above: “however, Lake Mead will operate under normal conditions in calendar year 2014, with water users in the Lower Colorado River Basin and Mexico receiving their full water orders in accordance with the 2007 Interim Guidelines and the 1944 Treaty with Mexico.”

    Arizona is certainly not perfect on water policy, but I’ve read the state water plans for both Texas and Arizona, and there’s no question whose plan is closer to realistically sustainable. Phoenix is in better shape for water than any other major metro area in the Southwest. Most folks don’t realize that Phoenix sits on a major river and has roughly 1maf a year of gravity flow surface water from SRP, before even talking about CAP water. The majority of water used in AZ is still for AG, it’s not Vegas.

    Also here in Texas, the Lower Colorado River Authority is saying the series of man-made lakes west of Austin will likely hit a new record low, below that of Texas’ drought of the 1950s, by the end of this year.

    As the former head of the Las Vegas Valley Water District (left in 1989) I gave a report that predicted severe water problems somewhere around 2010 – even with some conservation initiatives – and was essentially forced out largely due to that. Sadly you don’t have to be a ‘rocket scientist’ to figure out the problem and its magnitude. But looking at our political landscape today I am not optimistic about nearterm solutions – betting that severe economic dislocation and pressure will force huge societal changes.

    It seems like poetic justice. Texas, which has long assumed a much greater role for itself in the national conversation than is otherwise justified, simply by virtue of its energy industry is now about to become a beggar because of the same policies that mistakenly caused swagger. Hard to swagger when you’re down on your hands and knees begging for help you wouldn’t give anyone else. It reminds me of an old saying, “Tough titty said the kitty when the milk ran dry!”

    Peter begs a question when he avers ” it is time to grow less rice, alfalfa, cotton, and pasture with flood irrigation. It is past time to retire the green lawn as an acceptable landscape option in arid climates. All toilets and washing machines should be water- and energy-efficient.”

    His imperatves address only human demand as though nature did not take away water as well– every man , woman and child on Earth is losing a tonne of stored fresh water a day to solar evaporation.

    As long as we allow reservoirs to remain as dark and heat absorbing as asphalt- -water ordinarily absorbs 93% of the solar energy it intercepts, evaporation will take away more water than we can hope to conserve.

    The time to have acted is long past, the actions that could have saved us are still ignored. Combustion as a source of power is no longer practical, unlimited population expansion (consumption) is no longer practical. The Sept. 11 atrocity was our wake up call, we should have jumped up to poured our trillions into alternative energy development to wean ourselves off of our combustion addiction and its dealers, we should have turned our propaganda machine over to promoting thrift and family planning, instead we poured trillions into starting paranoid wars and developing fracking methods to expand our addiction still further, and we turned our propaganda machine over to the cause of promoting unlimited consumption and suppressing family planing. Way to go Americans, the biggest “classic fail” in all of history! Arrogance is the only enemy capable of defeating the United States, its an enemy we have no defense against and it seems to be winning.

  23. [...] Things are really bad, though.  Smaller towns in the Southwest are running out of fresh water.  Las Vegas is desperate to get more water pumped in from anywhere.  Water levels in Lake Mead are down 100 feet from normal.  Southern California has had to dig deeper and deeper for fresh water.  Fracking companies are competing with citizens for water.  This is doubly poisonous since not only are they taking fresh water from people who need it, they are also using that fresh water and chemicals to destroy the remaining fresh water.

    “limits to new supply”

    “turn to the demand side”

    Without reasonable pricing of water both of these are hopelessly out of step with economics. High water prices will incent new supply, whether the malthusians like it or not. Same for the opposite side of the coin

    The problem is exacerbated by bad policies and practice.
    Ernst & Young has recently released a report, offering a critical analysis and an actionable agenda.

    Among the issues the report discussed are:
    - Inefficient usage as aquifer/well levels run low
    - Mispricing
    - Unsustainable financing, especially given rising debt/deficits on local, state and national levels, inflation risk, and over reliance of low interest rates+dividend distribution
    - Bad bond rating practices
    - Huge increase in CAPEX needs coming up and climate change only adding to it
    - Decaying third-world type infrastructure – water main breaks everywhere
    - Lack of private sector involvement as compared to other countries
    - Lack of national strategy/coherent policies
    - Limited enforcement
    - Almost no supply side efficiency measures
    - Extreme conservatism/anti-innovation
    - Lacking and inconsistent data with limited quantitative management
    - High industry fragmentation, and much more if one was to dig deeper….

    Does it not occur to anyone that a dry semi-desert land just cannot support an endless population? If so you’d never know it.
    I looked in vain for any hint that anyone here thought we’d gone WAY beyond a reasonable population for the areas mentioned.

    In the 12th century AD, during the so-called “Medieval warming period”, the paleo evidence shows that the western half of the U.S. was a sand dune desert. The Colorado River ran very low for decades at a time. If this drying was a local extreme, caused by complex interactions among ocean currents and air masses from climate change, we may now be entering a repeat of the same performance.

    The climate denialists always include a bit of bad economics at the end of their speeches and writings, and insist that climate mitigation will destroy the economy. (This is notable, for example, in the public statements of MIT scientist Richard Lindzen, as well as in the vast outpourings of gibberish from the propagandist front groups such as the Heartland Institute. It appears to be the same uninformed and baseless anti-big-gov’t fear that animates the fiscal “austerians” in the current economic crisis.) They insist that carbon mitigation will wring an economic disaster, but clearly they haven’t costed-in many things, including the price tag on rehydrating the western half of the United States.
