From The Arizona Capitol Times (Howard Fischer):

A major player in the drought contingency plan on Thursday yanked its scheduled ratification of its part of the deal, potentially upending any chance of the state meeting the March 4 deadline set by the Bureau of Reclamation.

Stephen Roe Lewis, governor of the Gila River Indian Community, said he had called for a special meeting of the tribal council to consider and approve the necessary agreements to provide up to 500,000 acre feet of water between now and 2026. That was designed to help make up for the water that the state will no longer be able to draw from Lake Mead, much of that earmarked for Pinal County farmers.

But Lewis said he learned that House Speaker Rusty Bowers has his own hearing set for Tuesday on legislation that would affect the tribe’s rights to water from the Gila River. As a result, Lewis said he and the council have decided they won’t consider ratification.

“This step may very well prevent us from being in a position to approve the Arizona DCP implementation plan in time to meet the very real deadline established by the Bureau of Reclamation, or in fact ever,” Lewis said.

And the tribal governor made it clear who he thinks will be to blame if the whole deal falls apart.

“While Speaker Bowers’ action may have placed the future of DCP in serious jeopardy, it will not shake our determination to protect our water settlement,” Lewis wrote.

Bowers declined to comment on the latest development.

But an aide to the speaker said that, at this point, Bowers intends to pursue his legislation, even with the threat.
That echoes the comments Bowers made last month to Capitol Media Services when the tribe first said he has to drop his legislation.

“I’m not going to back down,” he said at the time.

And he lashed out at the tribe for trying to link the issues.

“This is just showing their mentality to everybody who gets in their way,” Bowers said. “It’s all ‘Our way or no way.’ ”

Gov. Doug Ducey, who has made approval of the DCP a key goal, sidestepped questions about the new hurdle, with press aide Patrick Ptak saying only that his boss is focused on working with other states to get Congress to approve necessary changes in federal law.

The legislation that threatens to blow up the deal, HB 2476, concerns at what point people who had one time had the right to divert water from the river lose those rights. As the law now reads, those rights were forfeited if the water was not used for at least five years.

Bowers wants to repeal all that. That, in turn, would affect ongoing lawsuits about who gets to claim water from the upper Gila River, water that the tribe says belongs to it because the prior users forfeited their rights.

From Arizona Central (Ian James):

MARICOPA — In satellite images, the farm fields in central Arizona stand out like an emerald green quilt draped across the desert landscape.

Seeing it from the ground level, the fields of alfalfa, corn and wheat are interspersed with the furrows of freshly plowed fields. After the cotton harvest, stray fluffy bolls lie scattered on the ground like patches of snow.

A large share of the water that flows to these fields comes from the Colorado River, and the supply of water is about to decrease dramatically.

Under Arizona’s plan for coping with drought, farmers who’ve received Colorado River water from the Central Arizona Project Canal for more than three decades now expect to see their allotment slashed more than 60 percent, from 275,000 acre-feet to 105,000 acre-feet per year for the first three years of a shortage. After that, their supply of Colorado River water will be cut off and they plan to rely solely on pumping groundwater from wells.

The plan to shut off deliveries of surface water to farms in Pinal County shows how the demands of agriculture are starting to collide like never before with water scarcity and climate change in the Southwest. The strategy of turning to groundwater pumping will test the limits of Arizona’s regulatory system for its desert aquifers, which targets some areas for pumping restrictions and leaves others with looser rules or no regulation at all.

In Pinal County, which falls under these groundwater rules, the return to a total reliance on wells reflects a major turning point and raises the possibility that this part of Arizona could again sink into a pattern of falling groundwater levels — just as it did decades ago, before the arrival of Colorado River water…

With the imported supply of water now about to go away, the farmers in the area are bracing for changes that they see approaching much more rapidly than they had anticipated. A first-ever shortage on the Colorado River could be declared starting next year. When the flow of water through the CAP canal decreases, no other group of people will feel the direct effects as acutely as the growers and laborers who run the farms in Pinal County…

“As I lose water, I will fallow land,” Thelander said as he drove his pickup past fields of cotton and alfalfa. “We’re going to have to lay off employees.”

Drought plan maps out new future

The Colorado River irrigates more than 5 million acres of farmlands and supplies about 40 million people in cities from Denver to Los Angeles.

Nineteen years of drought and chronic overuse, combined with the worsening effects of climate change, have pushed the levels of the river’s reservoirs lower and lower. Lake Mead, the country’s largest reservoir, now sits just 40 percent full and approaching a shortage.

Under the proposed Drought Contingency Plan for the river’s lower basin, Arizona would join with California and Nevada to take less water out of Lake Mead in an effort to prevent it from falling to disastrously low levels.

During the Legislature’s discussions of Arizona’s piece of the drought deal, the plan to provide state funding to Pinal irrigation districts prompted debate. There also was debate about how the agriculture economy will be affected.

The Arizona Municipal Water Users Association, which represents cities that supply water to more than half the state’s population, said in a Jan. 7 economic analysis that Pinal County agriculture represented about 0.2 percent of Arizona’s economy in 2016, and that about 11 percent of the county’s agriculture industry is at risk due to the water cutbacks under the Drought Contingency Plan.

While growers will have to shrink their crop irrigation by one-third on average, the association said, much of the county’s farming economy is based on dairies and beef production. It said feed for the cattle can be brought from outside Pinal County.

The county produces much of Arizona’s milk, and a large portion of the milk comes from Shamrock Farms. The dairy has about 12,000 cows…

Crop choices, groundwater use scrutinized

Given all the stresses on water supplies in the desert Southwest, the farmers in Pinal have faced questions about their choices of crops, their irrigation methods and their plan to rely on more groundwater pumping. Critics have asked whether it makes sense to continue growing thirsty crops like alfalfa and cotton in the desert. They’ve also called for more investment in using water more efficiently on the farms.

Sandy Bahr, who leads the Grand Canyon Chapter of the Sierra Club, criticized the plan to use taxpayers’ money for new wells and other water infrastructure. She said this goes against decades of water policy in Arizona aimed at reducing the pressures on groundwater supplies, from the construction of the Central Arizona Project canal starting in the 1970s to the passage of the state’s landmark Groundwater Management Act in 1980.

“After decades of trying to limit groundwater pumping, we see kind of this test of the Groundwater Management Act,” Bahr said. She said the plan approved by the Legislature will now promote more groundwater pumping and over-exploitation of aquifers.

If that’s going to be allowed, she asked, then shouldn’t the landowners in Pinal “have to pay for it themselves?”

Bahr said she’s concerned that the plan doesn’t involve looking at how different types of crops could help in using less water.

“Instead, almost every facet of what the Legislature passed is tied to getting water to these Pinal County interests,” she said.

Some conservationists and lawmakers have also raised questions about how efficiently water is being used on Pinal’s farms, and what steps could be taken to promote the installation of more water-saving irrigation systems.

Researchers who’ve looked at ways of improving irrigation methods have found big potential for saving water on farms, which use more than 70 percent of the water supply across the Colorado River basin. When researchers with the Pacific Institute, an Oakland-based water think tank, examined water use along the Colorado River in a 2013 study, they found that irrigating alfalfa more efficiently (through a practice known as “regulated deficit irrigation”) could save nearly 1 million acre-feet of water per year.

They also estimated that replacing about 10 percent of the alfalfa with cotton or wheat across the river basin could save about 250,000 acre-feet per year. That’s nearly half of the total water cutbacks that Arizona will have to face under the first year of a shortage.

Thelander said people often ask him about his choices of crops.

“I always get the question: Why don’t you farm crops that are more water-efficient?” he said. “We spend a tremendous amount of money on water. And if I could make money farming low-water use crops, I would do that. There’s already a big carrot there for us to do that.”

One example is barley, which he said is one of the lowest water-use crops that can be grown in the area.

“But if we farm barley, we lose a tremendous amount of money,” Thelander said. “We’re always looking for lower water-use crops that we can make a profit on.”

How Pinal got Colorado River water

In the 1930s, growers in Pinal County dug wells and began irrigating farms with groundwater. The farms expanded through the 1950s and kept relying on wells.

The agriculture investors in the ’50s and ’60s included the actor John Wayne, who bought land to grow cotton and raise cattle, and also invested in building a feedlot.

When construction began on the CAP Canal in 1973, the project promised to help sustain the farms in central Arizona while allowing them to draw less from the aquifers.

After decades of heavy pumping in Pinal County, the water tables had fallen dramatically. The ground sank in places as the aquifers were depleted. The overpumping and the sinking ground left lasting symptoms: In several areas around the region, gaping fissures opened up in the earth.

In 1985, construction began on a canal system that would run from the main CAP canal to the fields in Pinal’s Maricopa-Stanfield Irrigation and Drainage District. The district paid for the nearly $100 million canal system, issuing bonds and financing 80 percent of the cost with zero-interest loans from the federal government.

The first water deliveries flowed to farms in 1987, and the system was finished in 1989. It included the 56-mile Santa Rosa Canal, as well as the 17-mile East Main Canal and 130 miles of lateral canals. Through these arteries, the farms gained access to Colorado River water.

Brian Betcher helped design the project while working for a consulting firm in the early 1980s, and in 1988 he joined the Maricopa-Stanfield Irrigation and Drainage District as its engineer.

Under Arizona’s groundwater law, the farmlands were within the Pinal “active management area” and the regulatory system required that the irrigated areas not expand with the arrival of imported water.

“For every acre-foot of Colorado River water that was received, we had to reduce groundwater pumping by the same amount,” said Betcher, who is now the district’s general manager.

In 1989, the district assumed control of all the farms’ wells, acquiring them from the landowners with 40-year leases. The district has since delivered growers a mix of groundwater and Colorado River water.

While one of the reasons for building the CAP Canal was to help wean agriculture from groundwater, it was also to supply cities. And the Pinal farmers knew they were at the bottom of the list in the priority system.

As they began to irrigate with Colorado River water, Betcher said, the farmers were aware that the suburbs would continue to expand into farming areas and would have the highest priority for water.

“It was well-known that there would be a decreasing supply over time,” Betcher said. “It was pretty well understood that over time, the higher priority users, which were cities and industry, would grow into their allocations. And that would leave less water for agriculture.”

The irrigation districts’ initial contracts stipulated deliveries of Colorado River water through 2042. The way the system worked throughout the 1990s and into the early 2000s, Orme said, the districts were able to use the available water that remained after cities and Native American tribes had taken their allotments.

The contracts didn’t list specific quantities of water but rather percentages dividing what was left among the irrigation districts. So, exactly how much water would be available for agriculture in any year was never certain.

In the early 2000s, efforts to settle several water disputes were underway in Arizona. Among those issues: Leaders of the Gila River Indian Community were seeking to settle their longstanding water-rights claims; Arizona officials were in a dispute with the federal government over the repayment costs for the construction of the CAP canal; and the Pinal irrigation districts were in a disagreement with CAP officials over how much they were being charged for water.

When the parties reached the landmark 2004 settlement, the farmers agreed to take a step down in the water priority system. Some of the water that they had been using went to tribes and cities. In exchange, the farmers would get water for about a third of the price that CAP had proposed to charge.

At the time, Lake Mead was nearly full and the farmers felt confident they’d have an assured supply of water until 2030. Their group of water users, who took water from what was called the Agricultural Pool, faced a schedule of decreasing water deliveries between 2017 and 2030.

But the growers and their irrigation districts saw the deal as beneficial because, as Orme put it, “an affordable 25-year water supply is better than a 40-year unaffordable water supply.”

As Colorado River water has continued to flow to farms, it has allowed groundwater levels to stabilize and recover somewhat. In some areas, Betcher said, the water table has risen significantly.

Over the years, the city of Maricopa has grown and replaced some of the farmland in Pinal. Around Casa Grande, new subdivisions have also sprung up.

Even after losing some farmlands to development, the Maricopa-Stanfield district still has about 60,000 irrigated acres.

This year, the district plans to deliver 43 percent of its water from the CAP canal and get the remaining 57 percent from groundwater pumping. Even before the drought deal, the area has been gradually relying more on wells. Betcher said the district has a program to rehabilitate old wells and has added to its groundwater pumping capacity during the past decade.

Of the $50 million sought by irrigation districts in central Arizona, about $15 million would go to Betcher’s district. The money will go toward drilling new wells and building pipelines to carry the groundwater to the canal system.

Betcher said wells in the district are pumping water from 500-600 feet underground.

When the new wells go online, they will likely pump down the water table again. Just how quickly the aquifer may decline isn’t clear. Together with another irrigation district, Maricopa-Stanfield is paying a consultant to prepare a study evaluating the groundwater supply…

The farmers still could return to their current schedule of water deliveries, Orme said, under a scenario in which heavy snow and rain ends the 19-year drought and sends Lake Mead rebounding.

But even with the snowpack in the river’s upper basin about average so far this winter, a shortage still looks likely. And federal water managers have been pressing for the states to finish the Drought Contingency Plan. It’s unclear whether that will happen before a March 4 deadline set by the federal Bureau of Reclamation.
