#NewMexico: Concern over depletions from the #OgallalaAquifer @nmreport

From The New Mexico Political Report (Kendra Chamberlain):

The Ogallala aquifer is rapidly declining.

The large underground reservoir stretches from Wyoming and the Dakotas to New Mexico, with segments crossing key farmland in Texas, Nebraska, Kansas and Oklahoma. It serves as the main water source for what’s known as the breadbasket of America — an area that contributes at least a fifth of the total annual agricultural harvest in the United States.

The U.S. Geological Survey began warning about the aquifer’s depletion in the 1960s, though the severity of the issue seems to have only recently hit the mainstream. Farmers in places like Kansas are now grappling with the reality of dried up wells.

In New Mexico, the situation is more dire. The portions of the aquifer in eastern New Mexico are shallower than in other agricultural zones, and the water supply is running low.

In 2016, the New Mexico Bureau of Geology and Mineral Resources sent a team to Curry and Roosevelt counties to evaluate the lifespan of the aquifer. The news was not good. Researchers determined some areas of aquifer had just three to five years left before it would run dry given the current usage levels, potentially leaving thousands of residents and farmers without any local water source.

The news left local decision-makers in the region weighing options to balance farmland demand for irrigation and community needs for drinking water while a more permanent solution is put into place.

“There’s no policy in place to provide for that scenario,” David Landsford, who is currently mayor of Clovis and chairman of the Eastern New Mexico Water Utility Authority told NM Political Report.

Climate researchers and hydrogeologists agree these types of water scarcity issues will likely become more commonplace in the southwest and beyond as the climate further warms.

“Climate change, especially in the west and southwest, is already impacting us,” said Stacy Timmons, associate director of hydrogeology programs at the Bureau of Geology and Mineral Resources, at a National Ground Water Association conference in Albuquerque.

“There’s some places where we’re seeing some pretty remarkable declines in water availability that are, in some ways, reflecting climate change,” Timmons said. “You can see, just over the last twenty years, there’s been some pretty significant drought impacts to New Mexico, specifically.”

Timmons has assembled a team to head up a new initiative to help the state better track water use, quality and scarcity. The program revolves around data: aggregating all the water data that’s collected across different sectors, government agencies and research organizations in the state. The idea is that by collecting that data in one central location and making it available to everyone, policy makers will have a better understanding not only of current water resources, but also how to shape water management policies moving forward to reflect that reality.

“There’s a huge shift globally and nationally in how we’re looking at water,” Timmons said. “Here in New Mexico, we are really on the cutting edge of actually accessing some of this technology, and we’re starting to modernize how we manage our water and our water data.”

Water Data Act

New Mexico became only the second state in the country to prioritize water data management in statute when the Legislature passed the Water Data Act in 2019. The legislation garnered support from ranchers, farmers, environmentalists and, ultimately, state lawmakers. It passed both the House and Senate unanimously.

The Water Data Act aims to develop a modern, integrated approach to collecting, sharing and using water data. The act also established a fund to accept both state funds and grants and donations to support improvements to water data collection state-wide.

“It’s a tool in the tool box that’s going to help New Mexico as a whole manage our water,” said Rep. Gail Armstrong, R-Magdalena, one of the bill’s sponsors. “If it’s all kept in one place and is readily available, that becomes a tool for management.”

The program is just now getting off the ground, Timmons said. Part of the work has been to secure additional funding to run the program effectively, after much of the budget appropriation for the initiative was stripped from the legislation in committee.

“We have $110,000 to launch this effort — which is not enough, I will say,” Timmons said, but added that her team was able to leverage that money to receive additional grants and philanthropic funds.

The program will only be as effective as its data is descriptive — and getting all the data into the same place, in the same format, is a challenge. While government agencies and departments, including the USGS, the Interstate Stream Commission, the Office of the State Engineer and the New Mexico Environment Department, all collect and manage water data, they do so in different ways.

“There’s four or five or ten different agencies that have data about one location, but right now we don’t have one unifying way to coordinate all of those data sets,” Timmons said. “Everyone has their own way of managing it.”

And the team is also identifying where there are gaps in water data collection that can be addressed in the future.

“A lot of our rural parts of the state, there’s not a whole lot of data on them,” Timmons said. “There’s huge swaths of land where there are some water resources, there are some people on private domestic wells, and we just don’t have a great deal of information to evaluate what the water resources might be in those areas, or where there’s water quality concerns.”

“There’s very little useful information in the realm of metering of how much groundwater use is happening around the state,” she added.

Her team is working to locate, extract and codify the water data sets from those groups and aggregate that data into one central online database. The team has already set up an initial web portal where anyone can browse the data that’s already been uploaded.

Informing water policy

So how will that data help decision makers?

Timmons said that by better understanding how much water is left in our aquifers, and how that water is being used, communities will be better positioned to make decisions about how to craft water policy as the resource becomes more and more scarce.

“By sharing our data, it’s going to be more easily put towards operational decisions and broader state-wide decision making,” Timmons said. “We’re working over the next several years to bring in additional data providers and start pilot studies to utilize that data.”

Back in eastern New Mexico, communities in and around Clovis, Portales, Cannon Air Force Base and Texico are now tackling how to manage what’s left of Ogallala aquifer while securing a new water source.

The Eastern New Mexico Water Utility Authority broke ground on a project that officials believe will sustain the region and its agricultural demand for water. The plan is to build a pipeline to transport water from the Ute Reservoir north of the area to the water-scarce communities in Curry and Roosevelt counties. The project includes new wells being drilled in segments of the aquifer where there’s more groundwater to help support those communities while the rest of the pipeline is built.

The $527 million project will take years to complete, but Landsford said he expects portions of the pipeline to be operational and delivering water to customers in the next five to six years.

“It’s a step plan,” Landsford said. “Connect the communities, reserve some water, and then once you have additional groundwater secured in the interim, you can supply groundwater to the customers and spend the rest of the time getting to the reservoir, where the renewable supply is located. That’s the general blueprint for where we’re going.”

That type of thinking is emblematic of what Timmons’ described as a shift towards resiliency among communities and policymakers in the face of climate change and water scarcity.

“I’m beginning to see that there’s a paradigm shift happening, and there’s reason to be optimistic about the future, despite some of the doom and gloom data that we have,” Timmons said at the conference. “There’s really a new shift happening in how we think about water, especially here in the southwest. We acknowledge that, in many places where we’re using groundwater, we’re mining the aquifer. We need to be thinking about how we can increase the flexibility of that, and increase the redundancy in where we have water resources.”

“The term ‘sustainability’ has been used — especially when thinking about groundwater — it’s really out the window now,” she said. “We’re starting to think about it more in terms of resilience.”

2020 #OgallalaAquifer Summit in Amarillo, #TX, March 31 – April 1, 2020 — The #Kansas #Water Office

Here’s the release from the Kansas Water Office (Katie Patterson-Ingels, Amy Kremen):

8-State Conversation to Highlight Actions & Programs Benefitting the Aquifer, Ag, and Ogallala communities

The 2020 Ogallala Aquifer Summit will take place in Amarillo, Texas, from March 31 to April 1, bringing together water management leaders from all eight Ogallala region states: Colorado, Kansas, New Mexico, Nebraska, Oklahoma, Texas, South Dakota and Wyoming. The dynamic, interactive event will focus on encouraging exchange among participants about innovative programs and effective approaches being implemented to address the region’s significant water-related challenges.

“Tackling Tough Questions,” is the theme of the event. Workshops and speakers share and compare responses to questions such as: “What is the value of groundwater to current and future generations” and “how do locally-led actions aimed at addressing water challenges have larger-scale impact?”

“The summit provides a unique opportunity to strengthen collaborations among a diverse range of water-focused stakeholders,” said summit co-chair Meagan Schipanski, an associate professor in the Department of Soil and Crop Sciences at CSU. “Exploring where we have common vision and identifying innovative concepts or practices already being implemented can catalyze additional actions with potential to benefit the aquifer and Ogallala region communities over the short- and long-term.”

Schipanski co-directs the Ogallala Water Coordinated Agriculture Project (CAP) with Colorado Water Center director and summit co-chair Reagan Waskom, who is also a faculty member in Soil and Crop Sciences. The Ogallala Water CAP, supported by the U.S. Department of Agriculture’s National Institute of Food and Agriculture, has a multi-disciplinary team of 70 people based at 10 institutions in 6 Ogallala-region states, engaged in collaborative research and outreach aimed at sustaining agriculture and ecosystems in the region.

Some Ogallala Water CAP research and outreach results will be shared at the 2020 Ogallala Summit. The Ogallala Water CAP has led the coordination of this event, in partnership with colleagues at Texas A&M AgriLife, the Kansas Water Office, and the USDA-Agricultural Research Service-funded Ogallala Aquifer Program, with additional support provided by many other individuals and organizations from the eight Ogallala states.

The 2020 Summit will highlight several activities and outcomes inspired by or expanded as a result of the 2018 Ogallala Summit. Participants will include producers, irrigation company and commodity group representatives, students and academics, local and state policy makers, groundwater management district leaders, crop consultants, agricultural lenders, state and federal agency staff, and others, including new and returning summit participants.

“Water conservation technologies are helpful, and we need more of them, but human decision-making is the real key to conserving the Ogallala,” said Brent Auvermann, Center Director at Texas A&M AgriLife Research – Amarillo. “The emergence of voluntary associations among agricultural water users to reduce ground water use is an encouraging step, and we need to learn from those associations’ experiences with regard to what works, and what doesn’t, and what possibilities exist that don’t require expanding the regulatory state.”

The summit will take place over two half-days, starting at 11:00 a.m. Central Time on Tuesday, March 31 and concluding the next day on Wednesday, April 1 at 2:30 p.m. The event includes a casual evening social on the evening of March 31 that will feature screening of a portion of the film “Rising Water,” by Nebraska filmmaker Becky McMillen, followed by a panel discussion on effective agricultural water-related communications.

Visit the 2020 Ogallala summit webpage to see a detailed agenda, lodging info, and to access online registration. Pre-registration is required, and space is limited. The registration deadline is Saturday, March 21 at midnight Central Time.

This event is open to credentialed members of the media. Please RSVP to Katie.ingels@kwo.ks.gov or amy.kremen@colostate.edu.

Study Details Effectiveness of Kansas Program That Pays Farmers to Conserve Water — @UnivOfKansas

From the University of Kansas (Jon Niccum):

Crops need water. And in the central United States, the increasing scarcity of water resources is becoming a threat to the nation’s food production.

Tsvetan Tsvetanov, assistant professor of economics at the University of Kansas, has analyzed a pilot program intended to conserve water in the agriculture-dependent region. His article “The Effectiveness of a Water Right Retirement Program at Conserving Water,” co-written with fellow KU economics professor Dietrich Earnhart, is published in the current issue of Land Economics.

“Residential water use is mostly problematic in California, and not so much here in Kansas. However, people don’t realize that residential use is tiny compared to agricultural use,” Tsvetanov said.

“I don’t want to discourage efforts to conserve water use among residential households. But if we want to really make a difference, it’s the agricultural sector that needs to change its practices.”

That’s the impetus behind the Kansas Water Right Transition Assistance Program (WTAP).

“If you’re a farmer, you need water to irrigate. If you don’t irrigate, you don’t get to sell your crops, and you lose money. So the state says if you reduce the amount of water you use, it’s actually going to pay you. So it’s essentially compensating you to irrigate less,” he said.

But this is not a day-to-day solution. The state recompenses farmers to permanently retire their water rights. The five-year pilot program that began in 2008 offers up to $2,000 for every acre-foot retired.

This benefits the High Plains Aquifer, the world’s largest freshwater aquifer system, which is located beneath much of the Great Plains. Around 21 million acre-feet of water is withdrawn from this system, primarily for agricultural purposes.

Tsvetanov and Earnhart’s work distinguishes the effectiveness between two target areas: creek sub-basins and high-priority areas. Their study (which is the first to directly estimate the effects of water right retirement) found WTAP resulted in no reduction of usage in the creek areas but substantial reduction in the high-priority areas.

“Our first thought was, ‘That’s not what we expected,’” Tsvetanov said.

“The creeks are the geographic majority of what’s being covered by the policy. The high-priority areas are called that for a reason — they’ve been struggling for many years. Our best guess is that farmers there were more primed to respond to the policy because there is awareness things are not looking good, and something needs to be done. So as soon as a policy became available which compensated them for the reduction of water use, they were quicker to take advantage of it.”

Of the eight states sitting atop the High Plains Aquifer, Texas is the worst in terms of water depletion volume. However, Kansas suffers from the fastest rate of depletion during the past half-century.

“Things are quite dire,” Tsvetanov said. “The western part of Kansas is more arid, so they don’t get as much precipitation as we do here in the east. Something needs to change in the long run, and this is just the first step.”

Tsvetanov initially was studying solar adoption while doing his postdoctoral work at Yale University in Connecticut. When visiting KU for a job interview, he assumed the sunny quality of the Wheat State would be a great fit for his research. He soon realized that few policies incentivized the adoption of solar.

“At that point, I thought, ‘I can’t really adapt solar research to the state of Kansas because there’s not much going on here.’ And then I started getting more interested in water scarcity because this truly is a big local issue,” he said.

A native of Bulgaria who was raised in India (as a member of a diplomat’s family), Tsvetanov is now in his fifth year at KU. He studies energy and environmental economics, specifically how individual household choices factor into energy efficiency and renewable resources.

The state of Kansas spent $2.9 million in the half decade that the WTAP pilot program ran. Roughly 6,000 acre-feet of water rights were permanently retired.

“Maybe it’s a start, but it’s not something you would expect to stabilize the depletion,” Tsvetanov said. “This is just a drop in the bucket. Essentially what we need is some alternative source of income for those people living out there, aside from irrigation-intensive agriculture.”

Report: Simulating the sensitivity of evapotranspiration and streamflow to large-scale groundwater depletion

Click here to read the report. Here’s the abstract:

Groundwater pumping has caused marked aquifer storage declines over the past century. In addition to threatening the viability of groundwater-dependent economic activities, storage losses reshape the hydrologic landscape, shifting groundwater surface water exchanges and surface water availability. A more comprehensive understanding of modern groundwater-depleted systems is needed as we strive for improved simulations and more efficient water resources management. Here, we begin to address this gap by evaluating the impact of 100 years of groundwater declines across the continental United States on simulated watershed behavior. Subsurface storage losses reverberate throughout hydrologic systems, decreasing streamflow and evapotranspiration. Evapotranspiration declines are focused in water-limited periods and shallow groundwater regions. Streamflow losses are widespread and intensify along drainage networks, often occurring far from the point of groundwater abstraction. Our integrated approach illustrates the sensitivity of land surface simulations to groundwater storage levels and a path toward evaluating these connections in large-scale models.

From KUNC (Luke Runyon):

Groundwater pumping is causing rivers and small streams throughout the country to decline, according to a new study from researchers at the Colorado School of Mines and the University of Arizona.

“If you pump near a stream you’re going to change the amount of water that flows through the stream, because some of that stream water is going to basically get pulled to the well instead of flowing down the stream,” said Reed Maxwell, hydrologist at Colorado School of Mines and the study’s co-author.

Maxwell says his new study with hydrologist Laura Condon at the University of Arizona goes broad, quantifying the effect of pumping across the country.

“What we found is that we have actually depleted streams quite a bit,” Maxwell said.

The study finds that since the 1950s groundwater pumping has caused some stream flows to decline upwards of 50 percent. Some streams have disappeared from the surface altogether, seeping underground to refill pumped groundwater, the study finds.

Declines are particularly stark in portions of the Colorado River basin and on the Great Plains, Maxwell said.

Using a computer model, researchers were able to envision what rivers across the U.S. would’ve looked like without widespread groundwater pumping, which took hold in the 1950s.

Paper: Effects of management areas, #drought, and commodity prices on groundwater decline patterns across the #HighPlainsAquifer — Erin Haacker, et. al

The High Plains Aquifer provides 30 percent of the water used in the nation’s irrigated agriculture. The aquifer runs under South Dakota, Wyoming, Nebraska, Colorado, Kansas, Oklahoma, New Mexico and Texas.

We use an 82-year record of water table data from the High Plains Aquifer to introduce a new application of segmented regression to hydrogeology, and evaluate the effects of droughts, crop prices, and local groundwater management on groundwater level trajectories. Across the High Plains, we find discernable regional cycles of faster and slower water table declines. A parsimonious Classification And Regression Tree (CART) analysis details correlations between select explanatory variables and changes in water table trajectories, quantified as changes in slope of well hydrographs. Drying relative to prior-year conditions is associated with negative changes in slope; in the absence of drying conditions, steep declines in commodity price are associated with positive changes in hydrograph slopes. Establishment of a groundwater management area is not a strong predictor for change in water table trajectories, but more wells tend to have negative changes in around the time of management areas are formation, suggesting that drought conditions are associated with both negative deflections in water table trajectory and enactment of management areas. Segmented regression is a promising tool for groundwater managers to evaluate change thresholds and the effectiveness of management strategies on groundwater storage and decline, using readily available water table data.

The Republican River Water Conservation District Purchases Several Surface Water Rights: Irrigated acres associated with 27.5 CFS subject to dry-up

From the Republican River Water Conservation District via The Julesberg Advoacate:

In an effort to increase the surface water flows in the Republican River system, the Republican River Water Conservation District has recently purchased and leased multiple surface water rights on both the North Fork and South Fork Republican Rivers. By keeping the surface water in the river, the RRWCD is greatly enhancing the ability of the State of Colorado to stay in compliance with the Republican River Compact. Due to the extensive efforts of the RRWCD and the Colorado State Engineer’s office, Colorado will be in compliance with the Compact in 2019.

This will be the first year since the Final Settlement Stipulation was signed in 2002, that Colorado will be in compact compliance.

In the Annual Compact accounting 60% of all surface diversions are treated as depletions to the flows of the rivers and those depletions must be replaced through the Compact Compliance Pipeline. This requires considerably more water than off-setting comparable groundwater pumping. Last week, the RRWCD purchased the Hayes Creek Ditch and the Hayes Creek Ditch #3 surfacewater rights on a tributary of the North Fork Republican River. Some of these water rights were diverted each year, and the RRWCD was required to off-set those diversions with additional pumping from the compact compliance pipeline.

The RRWCD also purchased and leased a total of 27.5 cubic feet per second of surface water rights formerly owned by the Hutton Foundation Trust. Significant diversions on the South Fork have impacted Colorado’s efforts to come in to compliance with the Compact. As part of the Compact accounting there are tests for State Wide compliance and tests for each sub-basin. When calculating the sub-basin non-impairment test, additional diversions on the South Fork can contribute to a failure to meet the Compact non-compliance. By purchasing the surface water rights, the RRWCD can insure that the water will stay in the stream and will be measured at the state-line gage and again at the compact gage near Benkelman, NE.

After years of legal conflict, all entities can stop litigation because by purchasing these surface water rights, all legal actions by the Hutton Foundation Trust or by CPW, Inc. will be terminated. By purchasing the South Fork surface water rights, the RRWCD will not have to operate the Compact Compliance pipeline an additional 17 days that would be required to off-set the amount of water these rights would otherwise be entitled to divert.

The Republican River Compact Administration (RRCA) has approved the operation and accounting for the Compact Compliance Pipeline. As part of getting this approval, Colorado agreed to voluntarily retire up to 25,000 acres in the South Fork Focus Zone (SFFZ) by 2029. Colorado is pursuing 10,000 retired irrigated acres in the SFFZ by 2024 and an additional 15,000 retired irrigated acres by 2029.

Drying up the acres formerly irrigated by these surface water rights will contribute to the total of retired irrigated acres in the SFFZ, but Colorado is still far from the 10,000 acres to be retired by 2024.

The RRWCD continues to offer supplemental contracts for CREP and for EQIP conservation programs. The District offers increased annual payments for acres retired in the South Fork Focus Zone.

Currently the FSA, NRCS, the State of Colorado and the RRWCD are waiting for the USDA to publish the Rules and Regulations for the 2018 Farm Bill. As soon as the rules and regulations are published, producers can start applying for these conservation programs.

The consensus of the RRWCD Board is that by completing these purchases, it improves the ability to secure compact compliance now and into the future.

The RRWCD also approved a Water Use Fee Policy during the quarterly Board meeting on April 25th in Yuma. The Water Use Fee Policy includes a fee for junior surface water right diversions, and it modifies the annual fee for municipal and commercial wells. A copy of the fee policy is available on the RRWCD website at http://www.republicanriver.com.
