Mighty Rio Grande Now a Trickle Under Siege

FABENS, Tex. — On maps, the mighty Rio Grande meanders 1,900 miles, from 
southern Colorado’s San Juan Mountains to the Gulf of Mexico. But on the 
ground, farms and cities drink all but a trickle before it reaches the 
canal that irrigates Bobby Skov’s farm outside El Paso, hundreds of 
miles from the gulf.

Now, shriveled by the historic drought that has consumed California and 
most of the Southwest, that trickle has become a moist breath.

“It’s been progressively worse” since the early 2000s, Mr. Skov said 
during a pickup-truck tour of his spread last week, but he said his farm 
would muddle through — if the trend did not continue. “The jury’s out on 
that,” he said.

Drought’s grip on California grabs all the headlines. But from Texas to 
Arizona to Colorado, the entire West is under siege by changing weather 
patterns that have shrunk snowpacks, raised temperatures, spurred 
evaporation and reduced reservoirs to record lows.

In a region that has replumbed entire river systems to build cities and 
farms where they would not otherwise flourish, the drought is a historic 
challenge, and perhaps an enduring one. Many scientists say this is the 
harbinger of the permanently drier and hotter West that global warming 
will deliver later this century. If so, the water-rationing order issued 
this month by Gov. Jerry Brown of California could be merely a sign of 
things to come.

Arizona, a party to a Colorado River water-sharing compact among seven 
states, already is bracing for a first-ever reduction in its allotment 
within a couple of years should the river’s main reservoir, Lake Mead, 
continue falling beneath its current historic low.

Since coming to office two years ago, Interior Secretary Sally Jewell 
has elevated water management in the West to an agency priority. “The 
challenge is systemic and persistent across the West,” Michael Connor, 
the deputy secretary of the interior, said in an interview. “We need 
better infrastructure, better operation arrangements, better ways to 
share water and move water.”

The perils of drought are on ample display along the Rio Grande, where a 
rising thirst has tested farmers, fueled environmental battles over 
vanishing fish and pushed a water-rights dispute between Texas and New 
Mexico to the Supreme Court.

But you can also see glimmers of hope. Albuquerque, the biggest New 
Mexico city along the Rio Grande, has cut its water consumption by a 
quarter in 20 years even as its population has grown by a third. 
Irrigation districts and farmers — which consume perhaps seven of every 
10 gallons of river water — are turning to technology and ingenuity to 
make use of every drop of water given them.

John Fleck, a journalist and scholar at the University of New Mexico 
Water Resources Program who is finishing a book on the Colorado River, 
said no one should dismiss the gravity of the West’s plight. But neither 
is it necessarily ruination.

“This whole running-out-of-water thing isn’t really doom,” he said. 
“When water gets short, farmers get very clever.”

Mighty Rio Grande Now a Trickle Under SiegeAPRIL 12, 2015
An untamed, flash-flooding home to sturgeon and eels a century ago, much 
of the Rio Grande today is little more than a magnificently engineered 
pipe — diverted, straightened, dammed, bled by canals, linked by tunnel 
to the Colorado River basin in the north, surrendering its last trickle 
in the south to a ditch that supplies farmers near El Paso. Only miles 
later do Mexican tributaries renew its journey to the gulf. Its raison 
d’être is to sustain the booming society along its banks.

Mr. Skov, 44, is at the very end of that pipe. The canal that supplies 
his farm intercepts the Rio Grande near downtown El Paso, and flows 
through the city zoo. From parts of his 1,500 acres where he tends pecan 
trees and grows onions and alfalfa, he jokes, he could hit a nine-iron 
across the barren Rio Grande channel into Mexico.

In a perfect world, his crops could consume up to four feet of water in 
a growing season, and in flush times 15 years ago, the canal gave him 
most of that. “We’d double-crop — do onions and come back with corn 
after that,” he said. “We used to grow a lot of chiles, a lot of 
jalapeños. When water was abundant you could do a variety of things.”

That is a pleasant memory. Today Mr. Skov fallows a fifth of his fields, 
and canal water that once flowed from March to October arrives in June 
and vanishes as early as August. He makes up the deficit with two inches 
of treated water from the city sewage plant and a deluge of salty 
groundwater, brought up by once-abandoned wells that his grandfather 
dug, and that he has brought back to life.

The brackish water poisons the plants even as it saves them, cutting his 
yield by as much as a fifth. “It hurts germination, plant vigor, growth, 
root vigor, water absorption — everything negative that can happen to a 
plant,” he said.

Then again, the alternative is worse.

Across the West, the water shortages plaguing farmers and townspeople 
alike share many of the same causes. Like the Sacramento River in 
California and the Colorado River in the Rockies, the Rio Grande gets 
much of its flow from melting mountain snow — and snowpacks are getting 
smaller, and melting faster.

Rising temperatures are the reason. The federal Bureau of Reclamation, 
which manages much water in the West, reported in 2013 that average 
temperatures in the upper Rio Grande, in Colorado and New Mexico, rose 
almost 2.8 degrees during the 40 years ending in 2011 — and could rise 
an additional four to six degrees by 2100.

The 40-year increase, twice the global average, was beyond anything seen 
in the last 11,300 years. Future warming “has the potential to cause 
significant environmental harm and change the region’s hydrology,” the 
bureau’s analysis stated.

A warming climate turns some snow into rain and increases the 
evaporation and melting rate of what snow remains. And as drought 
worsens, dust and soot from parched soil and burning forests coat the 
snow and absorb sunlight, turbocharging the melting.

This month, federal forecasters pegged the runoff from mountain snowpack 
feeding the Rio Grande’s northern stretches at roughly half the average 
logged in the final two decades of the 20th century.

“The last four or five years running, we’ve had a weak snowpack, early 
melting and really dry spring weather,” said Mr. Fleck, the journalist 
and scholar. “The spring runoff usually peaks in early May. I think it 
may have peaked in March this year.”

It is likely to get worse. While acknowledging that climate forecasts 
are inherently uncertain, the reclamation bureau’s 2013 analysis 
concluded that the Rio Grande could lose roughly a third of its water by 
this century’s end.

In theory, the Rio Grande is engineered and managed to absorb such a 
whammy with as little misery as possible for the three million people 
who rely on it. In practice, some users have a comparative embarrassment 
of water, while others like Mr. Skov are water paupers.

The rules for sharing the Rio Grande are even more complex than its 
plumbing. Irrigation districts, governments and tribal authorities, 
among others, all have rights to water, and some have reservoirs devoted 
more or less exclusively to their use.

Some even band together: In the 1970s, Albuquerque and other New Mexico 
cities teamed with irrigators and the federal reclamation bureau to 
tunnel beneath the Continental Divide, diverting 28 billion gallons of 
water from a Colorado River tributary to a Rio Grande reservoir every year.

Yet the biggest agreement of all, the 1938 Rio Grande Compact among 
Colorado, New Mexico and Texas, shows just how fraught the divvying-up 
process can be.

The ménage has seldom been happy; for years, Colorado reneged on its 
obligation to deliver Rio Grande water downstream. But the thorniest 
issue of all is how the accord divides Elephant Butte Reservoir, New 
Mexico’s largest, between New Mexico and Texas.

Most of the reservoir’s water belongs to one of New Mexico’s biggest 
users of the Rio Grande — the Elephant Butte Irrigation District — and 
to the Texas irrigation district that parcels out river water to farmers 
like Mr. Skov, and to El Paso itself.

New Mexico manages the reservoir according to an agreed-on formula. In 
wet years, upstream users allow more water to flow past them to fill it 
up. In dry years, they keep more of the water to themselves, and let 
downstream users survive off what was stored during rainy periods.

That works perfectly in a climate where wet and dry years alternate. But 
over a dozen years of drought, the effect has been perverse; upstream 
users have more water, while at one point in 2013, Elephant Butte 
Reservoir shrank to 3 percent of its capacity.

“The Rio Grande Compact has been corrupted by climate,” said Phil King, 
a New Mexico State University engineering professor who advises the 
Elephant Butte district.

Supreme Court Case

Yet another aspect of the Elephant Butte agreement is before the Supreme 
Court. Texas and New Mexico agreed to a 57-to-43 percent split of their 
share of the reservoir, with Texas getting the smaller amount. But New 
Mexico farmers then sank wells along the river’s 100-mile route to 
Texas, soaking up groundwater that otherwise would have bolstered the 
river’s flow.

Texas complained bitterly for years. As the drought began to bite, it 
threatened to go to court, and the two sides struck a deal in 2008 that 
effectively gave Texas access to more water. But New Mexico’s attorney 
general sued to block it, and Texas took the dispute to the Supreme 
Court in 2013. Many observers believe it could win — and New Mexico 
could end up with even less water when it is needed most.

Experts say water users should stop fighting and start preparing 
together for a much drier future. “Individually, the American culture of 
using as much water as you want has got to stop,” said Pat Mulroy, a 
veteran Nevada water regulator who is a senior fellow at the Brookings 

On that point, at least, Texans and New Mexicans seem to agree. In many 
places along the Rio Grande, governments and farmers are both cutting 
their use of water and finding innovative ways to produce more of it.

For example, El Paso’s irrigation district and water authority are 
building their own 400-acre rainwater basin, and in 2017, the authority 
plans to build an $82 million plant to recycle sewage into 10 million 
gallons a day of drinkable water.

El Paso now uses less water per person — about 130 gallons a day — than 
any city in Texas. Per-person use in Albuquerque, which won an 
international award in 2006 for water conservation, reached a record low 
last year.

John Stomp, the chief operating officer at the Albuquerque Bernalillo 
County Water Utility Authority, said he believed that with further 
conservation efforts and more cooperation among water users, the Rio 
Grande’s users could withstand even a permanently more arid climate.

But “it won’t be easy,” he added. “Nothing about water is easy.”
