Decades of mismanagement by California are making the drought worse


California has been living in dream world for decades about water, allowing groundwater to be pumped without regulation, doing comparatively little to reuse and recycle water, and, in general, has seemed lackadaisical about water issues. Las Vegas, Phoenix, and Tucson use substantially less water per capita now compared to twenty years ago, storing water and reusing as much as possible. By contrast, California is the only western state that, until just recently, had no laws regulating water pumped from wells. (California’s newly enacted laws on groundwater pumping won’t help short-term. They will take years to implement and seem designed to be ineffective.)

The predictable result of such a greedy, shortsighted approach is that residential wells are going dry primarily because Big Ag can spend hundreds of thousands to drill deep wells and can then use much water as they want. This causes subsidence in the Central Valley as well as shallow wells going dry. And if too much water is pumped from aquifers, they lose the ability to hold water. What then, Mr. Pistachio Farmer?

The image from TakePart displayed here delineates the California’s problem. It’s a triple whammy of changing climate combined with an aging water infrastructure and archaic water law. Something does indeed have to change. And it is starting to. Pajaro Valley has a cutting edge “showers to flowers” recycling system. San Diego is building a ginormous desal plant. Big cities are beginning to mandate water usage cuts. San Jose just built a “toilet-to-tap” treatment facility. The cleaned-up water is drinkable, yet the city is hesitating about using the water for that for fear the public might be needlessly squeamish. (Vegas has had such facilities for years and the water is used for drinking.) These are all important moves in the right direction. Recycle water. Do more with less.

Naturally, the poor and disadvantaged suffer the most from water shortages.

500 wells in East Porterville have gone dry. The town has no water. Water is being trucked in to fire stations where residents collect it to use for washing, bathing, and drinking. Imagine having to do this on a daily basis. There are plans for a new pipeline, however it will take years. In the meantime, this little town may simply cease to exist.

Stratford still has water, but just barely.

Going into the fourth year of drought, farmers have pumped so much water that the water table below Stratford fell 100 feet in two years. Land in some spots in the Central Valley has dropped a foot a year.

In July, the town well cracked in three places. Household pipes spit black mud, then pale yellow water. After that, taps were dry for two weeks while the water district patched the steel well casing.

Drought is drying up wells everywhere in California, not just in the Central Valley

Landers, a onetime school secretary, does not live in the parched heart of the state: the San Joaquin Valley, where some people get sand when they turn on the faucet.

She has an acre in the Sierra foothills, in a sparsely populated town an hour northeast of Sacramento with a seemingly abundant water supply despite the drought. Except for one thing: Her water comes from a well. And her well, which is shallow, has gone dry.

And the drought will intensify for most of California for the next three months.

Tragedy of the Anticommons. Phoenix wants to store water, can’t

Phoenix admirably uses less water than it did decades ago, even as its population has grown hugely. The city wants to store its unused Colorado River allocation in Lake Mead for future use, but due to archaic, convoluted water laws, is not allowed to do so. This is the Tragedy of the Anticommons, where poor management leads to sub-optimal use of resources. As Butters once said on South Park, “Ouch, that makes my brain hurt.”

Inkstain unravels the tangled skein that allows such absurdities to happen. It should be noted that Phoenix storing water in Lake Mead would help southern Nevada, as it would mean less chance of water levels dropping below crucial Las Vegas intake pipes.

Prior to 2007, water use on the Lower Colorado River among Nevada, California, and Arizona was pretty much use-it-or-lose-it. The 2007 shortage sharing guidelines, an agreement among the states and the federal government, created a new management widget that changed that, called “Intentionally Created Surplus.” Lower Basin water users holding contracts with the Bureau of Reclamation could conserve water, jump through some bureaucratic hoops, and leave the water in Lake Mead for later. By the end of 2013, there was 1.1 million acre feet of ICS water in Lake Mead. In other words, this new institutional widget encouraged Lower Basin water users to conserve enough water to raise Mead’s elevation by something like 10 feet.

But Phoenix can’t use the ICS mechanism, because it is not a direct contractor. It gets its water instead through the Central Arizona Project, which as holder of the contract is the only one eligible for ICS. So CAP can store water in Mead, but Phoenix can’t.

Drought will persist or intensify in crucial California areas


The Sacramento and San Joaquin Rivers converge in the crucial Sacramento Delta. Water is pumped southward from there to the Central Valley and southern California and is fed by precipitation in the Sierra Nevadas. Unfortunately, the drought will persist in the Sierras, which is bad news for California. It doesn’t really matter if conditions improve in southern California as the vast bulk of its water comes from the Delta.

Some reservoirs in northern California are considerably lower than last year, with some being perilously low. Camp Far West is at a mere 4% of capacity.

In all, the state of reservoirs statewide means that the winter will need about 150 percent of its average precipitation, both rain and snow, to recover, said Ted Thomas, spokesman for the Department of Water Resources.

“If we get another dry winter, our reservoir storage will become even more critically low, and we would expect mandatory conservation to spread across the state,” Thomas said.

Los Angeles is beginning to offer incentives for drought-resistant lawns and water-saving appliances. This is a good start. However, it should have been done long ago. Further, if the drought worsens, then watering lawns should simply be banned.

However, the real solution is to raise the price of water, along with sharply-tiered pricing.

Arizona to California. Act like us to survive mega-drought

California, with the exception of some agriculture, can survive mega-drought by reusing water, implementing underground water storage, mandating xeriscaping, and treating water as a local product rather than assuming the Water Fairy will always deliver water as needed. Las Vegas already has toilet-to-tap reuse of water. Arizona and California will need to adopt such measures too. California will also need to strictly regulate groundwater pumping. It is the only state that doesn’t do so, which to my mind, is nearly criminal, and leads to such atrocities as water being pumped from desert aquifers to be used in bottled water. (Newly-passed California laws on groundwater pumping will take years to implement and are mostly toothless.)

According to the researchers, the state may weather the changes without experiencing serious economic or social difficulties, assuming it does one big thing:

Start acting more like Arizona where water is concerned.

Researchers at the University of California-Davis Center for Watershed Sciences constructed a computer model of the consequences of seven decades of drought in California. As reported in the Los Angeles Times, their findings were surprisingly upbeat. With some exceptions — notably the disappearance of a substantial amount of Imperial Valley agriculture — the California economy could thrive despite long-term mega-drought.

Australia survived a brutal drought recently by simply learning to use less water. California will no doubt do the same, especially if it becomes clear the previous 150 years were exceptionally wet.

Currently, California gets a huge share of Colorado River water, which discourages conservation. However, there is no way in Hell California would continue to get full allotments if cities in other states started to go dry. That simply would not be allowable politically, the Law of the River be damned.

Less hydropower, more natural gas generation due to California drought


In-state hydropower output dropped 50% from the norm in California in 2014. The difference is being made up with increased use of natural gas, as well as wind and solar. However, natural gas power does require substantial amounts of water for cooling, creating a bit of a Catch-22. California also imports large amounts of energy from big hydro in Washington and coal plants in Utah, Arizona, and New Mexico.

California’s drought, which began in 2011, has resulted in a significant decline in hydropower generation. On average, hydropower accounted for 20% of California’s in-state generation during the first six months of each year from 2004 to 2013. During the first half of 2014, however, hydropower accounted for only 10% of California’s total generation. Monthly hydropower generation in 2014 has fallen well below the 10-year range for each individual month.

Wind and solar generation are also playing an increasingly significant role in California’s generation mix. For the first time, wind generation surpassed hydro generation in California, doing so in both February and March of 2014.

The Columbia River Basin in Washington supplies 40% of hydropower in the US. Some parts are in drought but nowhere near as severe as California.

San Joaquin Valley subsidence. Irreversible damage from depleting aquifers


Once land subsides, it can never rise back up to where it had been. Worse, constant pumping of water from aquifers alters their structure, making them less able to hold water. The San Joaquin Valley in California is ground zero for unregulated groundwater pumping. Yes, California finally passed a law regulating groundwater pumping. However, it will be years before it is implemented and it’s mostly toothless. Meanwhile, crucial aquifers are overpumped, the earth is subsidizing, and aquifers canna take any more of this, captain.

Mavens Notebook has a comprehensive article on subsidence in the Central Valley. It is required reading for water wonks! Subsidence is some areas is now a foot a year and isimpacting the ability of crucial canals to carry water southward.

It’s been called the largest alteration of the earth’s surface. In the San Joaquin Valley, since the 1920s, farmers have relied on groundwater to varying degrees, and over time, overpumping of groundwater basin has caused the land to subside – over 30 feet in some locations.

We care about land subsidence for two reasons: Infrastructure damage and flood protection and damages to our natural resources, she said. “Water conveyance systems and other water infrastructure get damaged by subsidence because it’s happening at different rates at different locations. If the whole San Joaquin Valley was subsiding at the same rate and in the same way, then nobody would really care, but it’s this differential subsidence, the different amounts of subsidence in different places that really damages canals, roads, railways, pipelines, bridges – anything that crosses these areas of differential subsidence can get damaged.”

Canals are particularly sensitive because gravity is oftentimes used to move water, and this means that every point downstream needs to be at a lower elevation than every point upstream or pumps are needed.

“Coming tsunami” of dry wells in California’s Central Valley


It’s not just the drought. California’s refusal to be proactive about pumping water from wells is a major reason for shallow wells running dry. Wells that have been reliable for years are running dry in the San Joaquin Valley. Worse, water levels are dropping faster than normal. Thousands of residents have scheduled new wells to be drilled. The waiting list is months long. Some wells have already run dry. The extreme drought coupled with big ag drilling ever-deeper wells is dropping aquifer levels. California recently passed a toothless law regulating groundwater pumping however it will take years to implement. Other western states have regulated wells for decades.

The winter precipitation ended up about half of normal. Last week, Clark’s well went dry.

Clark is filling up water bottles at another neighbor’s house. She’s using it to cook, drink and flush the toilet. The shower is unusable. She’s eating off paper plates so she won’t have to wash dishes.

To bathe, she’s going to a relative’s house in Lemoore.

270 families in East Porterville, population 7,000, say their wells have run dry, a number which will certainly grow larger.

England said counting the number of dry wells is difficult because people don’t come forward fearing their children will be taken away if their home lacks a safe water source, or they believe that their home would be condemned, making them homeless.

Slightly optimistic Colorado River Basin water forecast. No change for Cali


The lower Colorado River Basin may get a bit more rain than normal for the next three months, which is certainly good. However it still looks dire for California and its all-important Sierras and Sacramento Delta.

The good news is that odds favor wet for the southerly part of the basin, especially Arizona and New Mexico. The “meh” part is that the low country doesn’t contribute much of the river’s overall supply. Most of that falls in the Rockies to the north, where the current forecast could be worse – slight tilt in the odds toward wet for a portion of the basin. But only slight.

However, Lake Mead and Lake Powell are at their combined lowest total since 1967.

California depleting groundwater reserves rapidly to grow almonds


“The people of the state of California are more or less destroying themselves in order to give cheap almonds to the world.” – David Zetland.

California grows 80% of the world’s almonds. Over one million acres on the Central Valley is now almond trees. The extreme drought and complete lack of laws regulating groundwater pumping means aquifer levels are dropping fast. Yes, California (finally) passed a weak law regulating groundwater. However it’s toothless and will take years to implement.

David Zetland, economics professor at Leiden University College in the Netherlands, says farmers are pumping water at a rate four to five times greater than can be replenished.

“The problem is that California, because of its failed institutions for managing water, is allowing these almonds to come on market at $3-$4 a pound wholesale, when the price would be tripled if California was managing its water sustainably and farmers faced the real cost of water.”

When it rains in Las Vegas, it can easily flood, hence the city has an elaborate system of flood channels. Water empties into this large basin, located in a residential area near South Point casino, where excess water can be stored befor releasing it downstream. This basin is about half a mile long and a quarter mile wide. The Clark County Regional Flood Control District wants to eliminate the possibility of damage from a 100-year flood. So far, 90 detention basins have been built along with 581 miles of channels and underground storm drains.
