Upper Rio Grande basin: The threats ahead — The #Alamosa Citizen #RioGrandeRiver

San Luis Valley Groundwater

Here’s Part 1 of the series from The Alamosa Citizen (Mark Obmascik):

The water supply of the San Luis Valley faces pressure as never before

THEY all remember when the San Luis Valley brimmed with water.

South of San Luis, Ronda Lobato raced the rising floodwaters in San Francisco Creek every spring to fill sandbags that protected her grandparents’ farm.

North of Center, potato farmer Sheldon Rockey faced so much spring mud that he had to learn to extract his stuck tractor.

Outside Monte Vista, Tyler Mitchell needed only a hand shovel on the family farm near Monte Vista to reach shallow underground flows in the Valley’s once-abundant water table.

Today those tales of plentiful water seem like a distant mirage. Ten of the past 11 years have delivered below-average snowpacks for the upper Rio Grande basin, with this year’s snowpack measuring just 58 percent of normal at the key May 1 measurement. All but one of the main local reservoirs were less than half-filled.

Farmers face significant cutbacks from wells now and likely from river flows and irrigation ditches later this season.

Against this stark backdrop of drought, three other vast changes loom.

The biggest is a state court judgment that came after decades of excessive well pumping by valley farmers and ranchers. Local irrigators now must restore 400,000 acre feet of water – more than 1.3 million people in metro Denver use in an entire year – to Valley groundwater systems within 10 years.

A second challenge is a plan by former Gov. Bill Owens and a metro Denver business group to pump and divert additional deep groundwater from the San Luis Valley to new buyers outside the San Luis Valley, likely on the Colorado Front Range.

And the third long-term issue is a forecast for flows to be reduced even further, perhaps as much as 30 percent, because of climate change, according to Colorado’s Rio Grande Implementation Plan.

Buffeted by drought, court orders, climate change, and Front Range diversion plans, the water supply of the San Luis Valley faces pressure as never before.

Shortages loom. Cuts seem inevitable.

“Our demand for water has far exceeded our supply for years, and now our supply is in a 20-year downward trend,” said state Sen. Cleave Simpson, general manager of the Rio Grande Water Conservation District. “We keep facing drought after drought. The sense of urgency continues to build.”

It all threatens the way of life for the 46,000 residents of the San Luis Valley, where agriculture is the driving economic force. Farming and ranching account for $340 million of sales each year while providing 18 percent of the region’s jobs. That puts agriculture behind only the government as a source of local employment. About one of every three dollars of basic income in the San Luis Valley comes from agriculture.

The San Luis Valley is the nation’s No. 5 producer of potatoes – behind only the tates of Idaho, Washington, Wisconsin, and Oregon – and a leading supplier of quinoa and alfalfa hay. (The Colorado Potato Administrative Committee says the San Luis Valley is the No. 2 producer in the U.S. for fresh potatoes.)

In a region long beset with poverty – one of every four Valley residents is impoverished, nearly double the statewide rate – farming and ranching have offered one economic success story. In Saguache County, the annual net income, or profit, per farm was $113,000, says the US Department of Agriculture census. Net income per farm in Rio Grande County was $105,000.

But all those jobs, all that money, hinge on one thing: an ample and dependable water supply.

“The climate of the San Luis Valley is arid, and a successful agricultural economy would not be possible without irrigation,” says the U.S. Geological Survey.

Average annual precipitation on the Valley floor is 7 to 10 inches, but potatoes, for example, need an additional 14 to 17 inches of irrigation water during the growing season. Alfalfa hay, the Valley’s top crop by acreage, requires up to 24 inches for a crop.

This adds up to an enormous thirst. According to state water engineers, San Luis Valley agriculture accounts for 810,000 acre feet of consumptive water use per year.

By contrast, the Denver Water Department needs only 247,000 acre feet of water to supply the 1.3 million people within its city and suburban service boundaries.

In other words, metro Denver requires only one third as much water as the San Luis Valley to produce a gross domestic product 60 times greater – a $202 billion annual economy vs. a $3.3 billion economy.

Because the San Luis Valley has so much water being put to comparatively low economic use, metro Denver water developers continue to focus a covetous eye on Rio Grande diversions.

After the AWDI proposals of the 1980s and the Gary Boyce plan of the 1990s, the Gov. Bill Owens-backed Renewable Water Resources proposal is the latest push to take advantage of relatively low prices to pipe water out of the San Luis Valley.

In the crosshairs is one of the oldest agricultural traditions and cultures in Colorado.

The first surface water right in Colorado, appropriated in 1852, is the People’s Ditch near San Luis. With a series of community irrigation canals called acequias, Hispanic settlers soon started growing food in the high desert with water from the Conejos, Rio Grande, Alamosa, Culebra, San Luis, Saguache, Carnero, and Trinchera, among other rivers and creeks.

By the 1870s, as much as 50,000 acres in the San Luis Valley was irrigated. After the arrival of the Denver and Rio Grande Railroad, that number soared to 400,000 acres by the 1880s. By 1900, demand for water in several valley streams already outstripped the natural supply.

Farmers responded by building reservoirs, and, especially, digging wells. By the time of World War I, the San Luis Valley was home to at least 5,000 groundwater wells. The rush was on. Underground supplies seemed endless.

Until they weren’t. In 1972, Colorado water officials ordered a moratorium on construction of new wells in most of the valley, and then ended new appropriations of groundwater in the rest of the valley in 1981, which was one of the worst snowpack years on record, with just 11 percent of normal on May 1.

Luckily, that one terrible year of drought in 1981 was followed by six successive years of some of the best snowpacks in the recorded history of the Rio Grande Basin. From 1982-1987, few worried much about groundwater because the rivers were flooding.

Another run of giant snowpacks in the mid-1990s helped to keep the pressure off groundwater pumping – while helping to build the memories of valley residents like Ronda Lobato, Sheldon Rockey, and Tyler Mitchell.

“I remember the snowbanks being bigger than me – the winters were so long and cold,” said Lobato, whose aunt and uncle lived along San Francisco Creek. “When the runoff came, we had to fill sandbags to protect against flooding. Today there is no water in San Francisco Creek. It doesn’t run at all.”

Farming is never easy, but water shortages make it even tougher, said Tyler Mitchell.

“I remember as a kid being able to dig with a shovel to find water. Now I might have to go 30 feet to find it,” said Mitchell, whose family runs 18 center pivot irrigation rigs. “The ditch water used to go all summer long. Now we’re lucky to get one month, and some ditches do only a few weeks. We don’t have enough surface water to grow cash-value crops every year.”

The mid-1990s were the heyday of San Luis Valley agriculture, said potato grower Sheldon Rockey, and that era changed the way of thinking for a generation of farmers.

“I remember when the river flooded three years in a row. I got the tractor stuck in the mud,” Rockey said. “There was a lot of money made without worrying much about water. The issue with the older crowd of farmers is that they were so successful for so long. Now that we’re in drought, it’s hard to change your thinking.”

The bountiful water years of the 1980s and 1990s in the San Luis Valley have flipped the typical generational divide in farming. Because they lived through the wettest times, the older farmers tend to have a brighter view than the younger farmers, local agricultural officials say.

“Farming is an optimistic profession,” said Heather Dutton, manager of the San Luis Valley Water Conservancy District and Rio Grande Basin representative on the Colorado Water Conservation Board. “People my father’s age have seen farming here at its best, when we had giant years for water. But the data and science don’t give me many reasons to think those days will come back around.

“If the big water years do come back, that would be tremendous. But I don’t want us to ignore the freight train coming at us right now.”

That train began blasting its horn about 20 years ago.

State water engineers long had been concerned about well-pumping by valley irrigators, but the connection between groundwater and surface water was not clearly understood. Starting in January 1976, engineers began monitoring the level of valley aquifers. Groundwater declined steadily but gradually, which led to the state moratoriums on drilling.

However, 2002 was the driest on record for the Rio Grande Basin, with a May snowpack of just 6 percent. With little available surface water, valley irrigators turned underground for supplies.

The result: In just one year, engineers recorded a 400,000 acre foot drop in Vvalley aquifers. That is a huge amount of water – a single acre-foot is enough to support two families of four people for a year.

In response to the vast agricultural overpumping came a flurry of laws, regulations, and court actions.

For the past decade, valley irrigators have been under a court order to maintain a sustainable aquifer system. That means restoring at least 400,000 acre feet to underground supplies, officials say. (Engineering studies say the unconfined aquifer actually has been drained by as much as 1 million acre feet since 1976.)

Little progress has been made to return that water in the past 10 years. Now irrigators face a 2031 deadline to repay the water debt.

Still, 5,000 irrigation wells continue to pump in the valley, including 3,000 in the key Subdistrict 1 north of Monte Vista and west of Hooper.

The $426,000 state Rio Grande Implementation Plan was blunt: “Because the sustained and lingering drought since 2002 has not been matched with a decline in agricultural consumptive use, use of the aquifers is unsustainable.”

What local water officials now fear is a replay in the San Luis Valley of what happened to irrigators on the South Platte River, where years of over-pumping by farmers, combined with a resulting state court order, led to the 2006 shutdown of 440 wells and the pumping curtailment of hundreds of others.

In the San Luis Valley, the clock is ticking. A reckoning awaits.

“Shutting down wells – there are people here who can’t survive that,” said Simpson, the state senator. “We are 10 years into this plan to create and maintain a sustainable aquifer system, but we are not yet back to where we started. There are no easy solutions.”

Scientists say it won’t get any easier. Because of climate change, a study by the Bureau of Reclamation, Sandia National Laboratories, and the U.S. Army Corps of Engineers forecasts even more challenges for water users in the Upper Rio Grande Basin:

  • Flows will decrease by 33 percent by 2100 at the Rio Grande near Del Norte, Conejos River near Mogote, Los Pinos River near Ortiz, and San Antonio River at Ortiz. Flows will decrease by 50 percent at the Rio Grande near Lobatos.
  • Peak river flows will come earlier, shifting from June to May.
  • Fewer water rights will be served. From 1950 to 1999, the average junior-most water right to be served in June on the Rio Grande was a 1910 priority, but by 2100 it will be an 1890 priority.
  • “We are an incredible agricultural community, but we don’t have the water supply we used to,” said Dutton, the Rio Grande representative on the Colorado Water Conservation Board. “There are more people who want water than there is water available. We are facing scarcity.”

    Not just agriculture at risk: In 2008, the state granted a water right to the Great Sand Dunes National Park and Preserve for the groundwater beneath its boundaries. The Valley’s extensive wetlands and river habitats support at least 13 threatened and endangered species and more than 260 species of birds including a major spring and fall flight of sandhill cranes.

    Here’s Part 2 in the series from The Alamosa Citizen (Mark Obmascik):

    Plan to pipe water to Front Range has big backers, few specifics

    THE Front Range executives who want to export water from the San Luis Valley to sell elsewhere are clear about a few things:

    They have money. They are backed by former Gov. Bill Owens. And they think their plan will benefit the Valley.

    Beyond that, however, details remain sketchy.

    Where exactly would the Renewable Water Resources project be built? Who are the investors? How much would it cost? What’s the project timetable? Who are the local supporters? Where are the customers?

    Also: If this project will truly help the San Luis Valley, then why are the political, water, and farm leaders of the Valley overwhelmingly against it?

    “We know San Luis Valley citizens are looking forward to jobs and an uptick in the local economy as a result of our project moving forward,” said Renewable Water Resources executives in a prepared statement. “Citizens responded favorably to the more than $50 million community fund – run by the community – that would be created to address critical issues which could include public education, economic diversity, senior assistance programs, conservation efforts, law enforcement, mental health services, and more.

    “We have asked the unelected Rio Grande Water Conservation District Board the following question, ‘What are you for?’ This question has been met with silence other than falling back on the status quo which means higher taxes and more regulation for the valley’s struggling farms and ranches.”

    Local officials say Renewable Water Resources is not to be trusted.

    “They continue to use false information to describe and promote their project,” said Heather Dutton, manager of the San Luis Valley Water Conservancy District and the Rio Grande Basin representative on the Colorado Water Conservation Board. “I don’t think people will fall for a bunch of falsehoods.”

    Valley native Ken Salazar – the former U.S. Secretary of the Interior, U.S. senator, state Attorney General, and current U.S. ambassador to Mexico – said the project would proceed “over my dead body.”

    Local opponents of the plan formed a group, Protect Our Water, that lists as members: 15 local water districts and entities; 22 cities and towns; 22 conservation and environmental groups; and two farm groups. It lists statements of opposition to the RWR proposal from eight separate local governments, including the Rio Grande Water Conservation District, the city of Alamosa, and Mineral and Rio Grande counties.

    The group says it is organized around a main principle: “There is no water available to move outside the San Luis Valley.” It has a web page dedicated to correcting what it says are RWR’s numerous misstatements about the project.

    RWR executives say they can’t be specific about project locations, timetables, or costs because they are focused on winning Valley support and filing a legal case in Colorado’s water court, which could take three to five years to process. That case would help determine whether the San Luis Valley has enough water for RWR to legally export without hurting existing users.

    In general, RWR says it wants to build a wellfield northeast of Moffat. A pipeline would carry water north along state Highway 17, more than 1,000 feet up and over Poncha Pass, to some uncertain location.

    Though a few Front Range cities such as Aurora and Colorado Springs draw some water from the Arkansas River basin, most metro Denver utilities rely on the South Platte River, a more distant location that would require a much longer pipeline and additional pumping costs for RWR.

    RWR says it has no identified customers for its proposed project. Executives have been pitching it to utilities on the Front Range.

    The financial incentives for RWR: Wholesale water prices are five to 10 times higher on the populated Front Range than in the agricultural San Luis Valley.

    In the San Luis Valley, RWR proposes to drill nearly a half-mile into the Valley’s deep aquifer to pump out 22,000 acre-feet of water per year. At the same time, RWR says it will buy and retire 31,000 acre feet of water currently used in the Valley for irrigated agriculture. As a result, RWR says a “surplus of 9,000 acre-feet will go back into the San Luis Valley’s shallow section of the aquifer.”

    The company says it is “investing $68 million to pay local farmers and ranchers who voluntarily wish to retire their water rights above market rate.”

    In addition to the purchase of those water rights, RWR said it will donate $50 million to a locally controlled community fund. The company expects that fund to generate $3 million to $4 million per year in contributions for local causes.

    RWR also has agreed to donate a 3,000-acre ranch for use as elk habitat near the Baca National Wildlife Refuge south of Crestone.

    “To give the above numbers some context,” RWR said in a statement, “the poverty rate of the San Luis Valley is greater than 35 percent and the average median household income is under $26,000. We do believe our commitments to the community will better the valley.”

    However, many questions remain unanswered. RWR declined to make available any project executives, including Owens, governor of Colorado from 1999-2007, for an interview for this story, insisting instead that all questions be written and answered via email.

    After years of water overuse, Valley irrigators now are operating under state orders to reduce consumption by hundreds of thousands of acre feet. Local water officials remain dubious that RWR can legally remove more water from a system already facing significant cutbacks.

    On top of the existing legal challenges, local engineers are girding for hydrologic changes caused by climate change. One state study estimated streamflows in the upper Rio Grande basin will plunge by a third in the next 80 years because of climate change.

    Project opponents now must toe a fine line politically. Though they want to highlight the current water shortages because of court rulings, continuing drought, and climate change, they don’t want farmers to give up hope and sell to RWR.

    In a Valley dominated by agricultural business, exporting water for other uses will throttle the future economy of the San Luis Valley, RWR opponents say. They point to the example of Crowley County in the lower Arkansas River Valley, where irrigators sold their supplies to Front Range cities, allowing a few farmers to reap big paydays at the expense of the rest of the southeastern Colorado economy.

    An irrigator who drops out of a local ditch makes it harder economically for remaining farmers to continue to operate and maintain the ditch.

    Many local farmers say buy-and-dry policies threaten the future of agriculture in the Valley.

    “Our community is centered on water and farming, and I hope the community sticks together,” said potato farmer Tyler Mitchell. “But in the grand scheme of life, money talks. If the price is right, you might see people sell. I really hope it doesn’t come to that.”

    Mitchell and other farmers are heartened by the Valley’s history of defeating other water export proposals.

    In the 1980s, former Gov. Dick Lamm and American Water Development Inc. sought to develop and export as much as 200,000 acre-feet per year from the Valley’s confined aquifer. After five years of litigation and a lengthy trial, AWDI lost in court.

    In the 1990s, Stockman’s Water, led by Monte Vista native Gary Boyce, purchased the Baca Ranch and proposed to export 150,000 acre-feet of water per year from the Valley. Boyce lost two statewide votes and struggled in water court. The Nature Conservancy bought the Baca Ranch in 2002.

    Most political leaders in the Valley supported a drive to convert the Great Sand Dunes into a national park partly to help prevent water exports from the Valley. In 2008, the state granted a water right to the Great Sand Dunes National Park and Preserve for the groundwater beneath its boundaries.

    According to the state’s Rio Grande Implementation Plan, it was the first nonconsumptive water right issued by the state of Colorado. “The water right precludes any withdrawal of water from the aquifers that would cause injury to the park’s environments, which are dependent on the groundwater,” the state plan says.

    The Valley’s extensive wetlands and river habitats support at least 13 threatened and endangered species and more than 260 species of birds, including a major spring and fall flight of sandhill cranes and the endangered southwestern willow flycatcher.

    Still, Sean Tonner, former deputy chief of staff to Gov. Bill Owens, led a drive to buy 11,500 acres of the Rancho Rosado from the former holdings of Boyce, who died in 2016.

    The result is the current RWR project proposal, led by Tonner and backed by Owens and other former members of his gubernatorial administration.

    (A detailed explanation of the history of San Luis Valley water export proposals, conducted by the University of Colorado Law School, is here.)

    “Because of our project offerings – with this proposal – we can enrich the local economy, bring more jobs to the area, support essential non-profits and community groups, and improve the health of the area’s aquatic habits and wildlife,” RWR said in a statement.

    The Protect Our Water coalition strongly disagrees.

    “A plan being proposed by Renewable Water Resources will remove water from the Valley and permanently dry up at least 10,000 acres of farmland,” the group says. “It could also negatively impact the environment, including streams, rivers, The Great Sand Dunes National Park, refuges, wetlands, fish and wildlife. Water sustains our economy and lifestyle.

    “There is no water available to move outside the San Luis Valley.”

    State monitoring finds elevated air pollution levels near Suncor refinery in #CommerceCity — #Colorado Newsline

    A state effort to measure air pollution levels near the Suncor Energy oil refinery in Commerce City found elevated levels of hazardous particulate matter in the area, officials with the Colorado Department of Public Health and Environment said in a communication to residents Thursday.

    The new data were collected by CDPHE’s mobile air monitoring lab, which was stationed at the Eagle Pointe Recreation Center in Commerce City between May 14 and July 17. They showed that levels of fine particle pollution — an air pollutant known as PM2.5 because it consists of tiny particles less than 2.5 microns in diameter — were higher in the Commerce City and north Denver area in early summer than at many other monitoring stations along the Front Range.

    GET THE MORNING HEADLINES DELIVERED TO YOUR INBOX

    “CDPHE sent the mobile lab to the area because of department and community concerns regarding air quality in the area,” the department said. “Fine particle pollution in the area comes from local sources, such as Suncor and vehicles, and more distant sources, such as wildfire smoke. The mobile lab is not able to determine the sources of pollution it measures.”

    The mobile lab was stationed less than a mile from the boundaries of the Suncor refinery, closer than any of the state’s permanent monitoring stations are located. The refinery and other industrial facilities in the north Denver metro area are known to emit high levels of pollutants, but environmental activists and residents, many of whom are low-income and people of color, have long complained that the area has lacked adequate air-quality monitoring.

    The results of the state’s air monitoring investigation suggest that PM2.5 is the “most prominent pollutant of health concern in the area,” CDPHE said. Levels of another common pollutant, ozone, were lower on average than in many other parts of the Denver metro area.

    The effort also found that levels of volatile organic compounds, or VOCs, “did not reach levels experts expect would cause health impacts,” though CDPHE officials cautioned that scientists don’t yet fully understand how VOCs may interact with each other or other pollutants to cause or exacerbate health impacts. “Whether someone might experience health impacts depends on many factors, including the amount they are exposed to and for how long,” said a CDPHE website showing the results of the investigation.

    The department says that it’s planning to send the mobile lab back to the Commerce City area in the future. It’s one of several efforts to improve air monitoring in the area surrounding the Suncor facility, including a grant-funded community program operated by the nonprofit Cultivando; new requirements for “fenceline” monitoring mandated by legislation passed earlier this year; and a voluntary monitoring website recently launched by Suncor itself.
