The Rio Grande County Board of Commissioners is the latest government body to place a moratorium on data centers. The commissioners also adopted a resolution prohibiting any large-scale, or hyperscale data centers in the county. 

During Wednesday’s regular meeting, the commissioners unanimously approved the year-long data center moratorium to allow the county’s departments to address land use codes. The moratorium is broad as existing language relating to data centers didn’t exist in the county’s codes before. The separate resolution prohibiting large-scale and hyperscale data centers was approved unanimously. 

Commissioners said they are using Colorado Municipal League definitions for large-scale and hyperscale.

This decision comes two weeks after a public hearing and work session that allowed county department heads and commissioners to hear the concerns from the public. 

Rio Grande County Administrator Skip Schoen said there has been “considerable concern” in the county about data centers as “a category.” 

More than 30 people spoke at the public hearing with more members of the public writing in their comments. 

The public concern in Rio Grande County echoes widespread concern about data center construction in the rest of the San Luis Valley and much of the country. 

Saguache County, the town of South Fork and Costilla County have already adopted varying moratoriums and resolutions to address data centers. 

Alamosa County has yet to signal an intent to place a moratorium on data centers as it is currently going through a process with a company called Strata Inc. that intends to build a small-scale, closed loop-cooled data center in the county. 

The city of Alamosa will take up a resolution to place a temporary moratorium on “Utility Scale Battery Energy Storage Systems and Large Load Data Centers” during Wednesday night’s regular meeting.

The different sides each presented closing arguments, but it was the reflections of Division 3 Water Court Judge Michael Gonzales that had the courtroom thinking as he brought to a close the water trial dealing with the Subdistrict 1 Fourth Amended Plan of Water Management.

At times it was a bruising trial Gonzales noted Thursday in his closing remarks, as he encouraged all the parties to move on and to not let the four-week trial wear on them and their own personal relationships. 

“We all know that there’s no way this court can fashion an order or an opinion that’s going to satisfy everybody. It’s just not going to happen,” the judge said. “I mean, it can’t because we know that we have mutually exclusive and competing interests. We know that this petition when it was created recognized that, but we still said ‘cooperation’ and all those nice things. And in reality, I think we all knew at some point that was going to come to a head. And I think we’re there, but that doesn’t mean we still don’t move forward.”

San Luis Valley Groundwater

This was the big water trial because it dealt with a plan to recover the unconfined aquifer of the Upper Rio Grande Basin, Gonzales noted. He pointed to testimony of Mosca-area farmer Lyle Nissen as one he enjoyed the most.

“I just loved his testimony. Someone who’s made some recognition, someone who’s made some changes, someone who didn’t come in here and complain and just said, ‘This is how it is. I recognize it and I move forward.’ And that was great to hear,” Gonzales said.

He also referenced a term he learned during the course of the trial, “deep percolation,” and used it to provide further insight into his thinking.

“I sat in my back yard and I watched the rain come down,” he said of the week’s weather. “I watched puddles form and I thought about my second favorite term from this trial, ‘deep percolation’ and I said, ‘Aha.’ And then I came back 10 minutes later and that puddle was completely gone. I said, ‘Wow.’

“I also sat there and I thought about the testimony I think was from this current state engineer when he said that we need rainstorms of biblical proportion to get us where we need to be, and that hit home. And no matter how wonderful that rain was, there needs to be things that happen.”

The state Division of Water Resources and the Rio Grande Water Conservation District are asking Gonzales to reject the protestors’ arguments and approve the plan. Without it, they argued, the unconfined aquifer won’t recover and broad groundwater well curtailment in the subdistrict becomes inevitable.

The cornerstone of the new plan is the “one-for-one” feature, which limits groundwater pumping to the amount of natural surface water that flows into the subdistrict over a five-year running average. The intent is to put more water into the unconfined aquifer system than is taken out and one-for-one pumping guarantees that, according to the state and subdistrict. 

Gonzales noted “the monstrosity of an equation” within the Fourth Amended Plan when he was quizzing Rio Grande Water Conservation District attorney Pete Ampe during his closing remarks. 

The one-for-one pumping feature, the equation to determine success, and a new “depletion fee” that sets the value of water in the subdistrict at $500 per acre-foot were all argued over, discussed and debated throughout the month-long trial.

Attorney Mirko Kruse, representing his family’s farming interest, and attorney Andy Jones, representing L Cross Ranch, want Gonzales to refer the plan back to the subdistrict for adjustments they’re requesting but are otherwise good with the plan.

Two other protesting groups, Northeast Water Users Association and Sustainable Water Augmentation Group, want the plan tossed entirely on grounds it isn’t legal; they asked Gonzales to order the subdistrict to only make changes to the existing third plan of water management.

Gonzales told all the attorneys to address Rule 8.7 of the state groundwater rules governing the Upper Rio Grande Basin. That rule determines how “proportional responsibility for maintaining a sustainable water supply is divided among all the well users within the Response Area.” 

It gets to one of the key arguments made by SWAG and its belief that groundwater irrigators like their clients are being illegally targeted and asked to share a disproportionate share of the burden in the unconfined aquifer recovery efforts.

Gonzales provided a timeline that leads to this Thanksgiving for when all the case documents and filings will be completed and he can begin his deliberations.

“I guess if there’s one message that we all need to take to heart is that we need to change the things we’ve been doing,” Gonzales said in completing his comments. “We can’t continue down the path we’ve been because if we think that’s the only way we can go, we’re dooming our children, our children’s children. And I don’t want to be a part of that time.”

Division 3 Water Court Judge Michael Gonzales: It looks like both sides are ‘setting up an appeal’; Allowing testimony from former state engineer is the latest objection — Chris Lopez (AlamosaCitizen.com) #SanLuisValley #RioGrande

July 21, 2026

Little doubt was left following the conclusion of Tuesday’s [July 21, 2026] water court session that the Subdistrict 1 Fourth Amended Plan of Water Management will ultimately be decided on appeal by the Colorado Supreme Court.

Division 3 Water Court Judge Michael Gonzales said as much as he ruled, following arguments, to allow testimony from former state engineer Kevin Rein, who is expected to testify as a rebuttal witness on Wednesday morning.

Ryan Donovan, attorney for the Northeast Water Users Association and Sustainable Water Augmentation Group which are protesting the subdistrict plan, argued that Rein should not be allowed to testify as a “lay witness” to rebut the testimony of SWAG expert witness Ken Knox. 

He also told Gonzales that his comments at the conclusion of the court session on Friday, July 17, where the judge made known his interest in hearing from Rein, created the appearance of impropriety which would be grounds for appeal should Gonzales rule against NWUA and SWAG in their bid to have the plan rejected by the water court.

“Now the supporters wish to call the exact witness identified by the court to the stand and are using the court’s statement as a basis for doing so. This tells me that the supporters would not be calling Mr. Rein, but for those statements. The extent the court relies on Mr. Rein’s testimony to fill the gaps in the state’s case and Mr. Rein’s testimony serves as a basis for the court’s ruling, NWUA and SWAG certainly have a colorful issue on appeal because the statements and the proponent’s subsequent action in response to those statements create the appearance of impropriety,” Donovan said.

In making his ruling that Rein could testify and that Rein’s testimony would be part of the court’s deliberations, Gonzales told Donovan and Subdistrict 1 attorney Pete Ampe that from his perspective, it’s felt that all sides have been working toward an appeal rather than to convince him.

“Pretty much all the evidence I’ve heard for the last three weeks has been cumulative, could be considered a waste of time and confusing. The same argument you just made for the evidence that I potentially could hear from Mr. Rein … I’ve let you guys present as much evidence as possible. I think maybe I have sustained two objections the entirety of the trial so that all the evidence comes in so the court has a basis to make what I would call a very ‘unenviable decision’ to quote language used by others and to be able to rely on enough information, sufficient information. 

“I’ve let it all come in. I haven’t stopped, really, anybody from presenting any evidence during the course of these proceedings. Quite frankly, I will tell you from my perspective…it’s felt like no one really has been concerned as to what decision this court is going to make because you’ve been setting up an appeal from the very beginning on both sides, on all sides.That’s what it’s felt like,” Gonzales said.

Earlier in the day, Jake Burris, president of the Subdistrict 1 Board of Managers, and Subdistrict 1 farmer Lyle Nissen testified in support of the Fourth Amended Plan as rebuttal witnesses to testimony from farmers SWAG put on the witness stand.

Nissen walked the court through all the ways he has retooled his farming operation in light of the declining unconfined aquifer.

“It is a different day, a different time. We’ve got to have rules. We have to have parameters. We have to get to the point where we’re sustainable,” Nissen told the court.

The water trial resumes Wednesday [July 22, 2026], with final arguments coming as early as Thursday.

Water trial set to wrap up this week: Former state engineer, Kevin Rein, to testify before final arguments — Chris Lopez (AlamosaCitizen.com) #SanLuisValley #RioGrande

July 17, 2026

The Colorado Division 3 water trial that virtually every farmer and rancher who operates in the Upper Rio Grande Basin is paying attention to is on track to wrap up this week, with former State Engineer Kevin Rein scheduled to testify before final arguments are made, Judge Michael Gonzales signaled Monday.

San Luis Valley Groundwater

The trial in Alamosa water court deals with the Fourth Amended Plan of Water Management for Subdistrict 1 of the Rio Grande Water Conservation District, which outlines a new approach to the aquifer recovery by limiting the subdistrict’s groundwater withdrawals to the amount of surface water that naturally comes into the lands annually. It is the subdistrict with the largest cash crop receipts in the Valley’s growing fields, the subdistrict with the largest volume of groundwater pumping, and the subdistrict under orders from the state to recover the basin’s shallow unconfined aquifer.

The new plan, approved by Rein before he retired as state engineer in 2023, has been dissected by farming operations protesting the plan in water court by arguing groundwater irrigators will be driven out of business because of the plan’s limits on groundwater pumping and a hefty $500 per-acre-foot pumping fee.

“It will be a hard nut to crack,” Dee Greeman, who works the L Cross Ranch, testified Monday. 

L Cross is among the operations protesting the plan. Given the multi-decade drought conditions, the overpumping fee and the fact L Cross would no longer be allowed under the new plan to offset its pumping with its own surface water as credits to its groundwater withdrawals, the value of the ranch would be affected long term, Greeman told the court.

“It’s a gamestopper,” he said, if wells can’t pump because it is from its groundwater pumping that L Cross finds profit in producing hay.

Greeman’s testimony on Monday wrapped up presentations by the different protestors to the plan. The state Division of Water Resources, which is defending the plan, will bring back witnesses to rebut different testimony and key to it all will be Rein.

It was the testimony of former state Division of Water Resources engineer Ken Knox at the conclusion of week 3 of the trial that prompted Gonzales to tell the state that it is only common sense for Rein to testify. Knox trashed Rein’s review, saying it didn’t take all the proper steps and didn’t include all the critical information for a state engineer to conduct a review of a water management plan.

Following a motion Monday by Preston Hartman, the state assistant attorney general defending the Fourth Amended Plan in water court, to dismiss the protestors case, Gonzales ruled that the protestors have provided sufficient evidence to keep going and scheduled closing arguments for the end of week after Rein testifies on Wednesday.

Once the final arguments are made, Gonzales will set a timeline for his review and decision.

“This is not something we want to push out too far,” the judge said at the conclusion of Monday’s session.

July 17, 2026

Colorado Division 3 Water Court Judge Michael Gonzales said from the bench Friday that he wants to hear from former State Engineer Kevin Rein and without his testimony it will be “very hard for this court” and its decision on whether to allow the Fourth Amended Plan of Water Management in Subdistrict 1 to go into effect.

And that’s how Week 3 of the most important water trial in the past 25 years affecting the Upper Rio Grande Basin ended in Alamosa water court – the judge telling the state Division of Water Resources as it defends the plan that he would like to hear from the state engineer who approved the plan.

“Without hearing from Mr. Rein, it’s a concern,” Gonzales said.

Earlier during Friday’s afternoon session, he cautioned attorneys on their tone and their questioning of witnesses in a week when emotions inside the courtroom ran high.

“Let’s everybody cool their jets,” the judge said before he added an extra 10 minutes to the afternoon courtroom break.

The week opened with State Engineer Jason Ullman telling Gonzales that without the Fourth Amended Plan in action, Subdistrict 1 faces widespread curtailment since it will not meet the “sustainable” level of the unconfined aquifer by 2031 when the current plan of water management expires.

In 2018 Rein first alerted the Rio Grande Water Conservation District that broad curtailment could be on the table given the lack of progress in restoring the unconfined aquifer. It was then the subdistrict began working on a fourth amendment to its water management plan, which was ultimately adopted by the Subdistrict 1 board and then the Rio Grande Water Conservation District before Rein gave his sign off.

Ullman, who succeeded Rein as state engineer, told the court as he wrapped up his testimony that in his view the Fourth Amended Plan of Water Management, which features a one-for-one pumping mechanism, is the “most reasonable I can think of that would be likely to cause the aquifer to increase in level.”

The one-for-one features means the subdistrict would offset its groundwater withdrawals by returning an acre-foot of water for every acre-foot pumped during the irrigation season. The new plan also contains an overpumping fee of $500 per acre-foot which groundwater irrigators would pay if they cannot offset their groundwater withdrawals with their own surface water or surface water credits.

“Like I said, I understand that that decision has consequences, but there’s pretty significant consequences to doing something. And at some point as the policy decision makers, we have to make a decision to do something to meet these goals the General Assembly has set out. And I feel like that’s what we’ve done here. The consequences of doing nothing are much more drastic and draconian than the consequences of this plan,” Ullman told the court.

It was Rein’s review and sign off on the Fourth Amended Plan that has come under scrutiny by opponents to the plan. Rein retired at the end of 2023 after approving the plan and conducted this exit interview with Alamosa Citizen. During the conversation for an episode of The Valley Pod, he was reluctant to dive into the details of the plan because it was headed to water court and Judge Gonzales for a legal review.

In this exchange Rein was referring to litigation of the Rio Grande Compact and litigation over the Fourth Amended Plan of Water Management for Subdistrict 1 when he talked on The Valley Pod in December 2023.

San Luis Valley Groundwater

“Without saying too much about that and the groundwater management plan for the subdistrict, from my perspective as a state engineer, there’s one critical aspect of that for both cases and that is the sustainability of the unconfined aquifer. As we know, that’s a difficult component of groundwater management in the Valley because we have a statutorily required sustainability objective. And that has found its way into the rules and into the groundwater management plan for the subdistrict,” he said at the time.

He added that under the existing plan of water management for Subdistrict 1, “it’s going to be very difficult to meet that sustainability objective … And I know that the subdistrict has worked hard toward an alternative in this current plan that I approved and is before the court, and the way that plays out is going to be so important to the irrigators in the Valley.”

Ken Knox, a former employee of state Division of Water Resources who at one point served as acting state engineer for approximately 18 months, criticized Rein during his testimony Friday for not conducting a thorough review and that the plan in sections was “devoid of necessary information” to approve the plan by the state engineer.

Rein’s review was a “dramatic step backwards for professionalism of agency standards,” Knox told the court. He was the final expert witness for the Northeast Water Users Association and Sustainable Water Augmentation Group, who are asking Gonzales to throw the plan out on legal grounds.

Rein’s review was a “dramatic step backwards for professionalism of agency standards,” Knox told the court. He was the final expert witness for the Northeast Water Users Association and Sustainable Water Augmentation Group, who are asking Gonzales to throw the plan out on legal grounds.

The farmers opposing the plan are trying to thread a few legal arguments to persuade Judge Gonzales to reject the plan. Their contention is the Northeast Water Users Association and Sustainable Water Augmentation Group are being asked to bear a disproportionate share of the burden in the aquifer recovery efforts because they are groundwater irrigators. They contend Rein didn’t conduct a full legal review of the sustainability and proportionality rules contained in state statutes governing recovery of the unconfined aquifer and the $500 fee makes the plan beyond the economic means of all the irrigators who hold water rights in the subdistrict.

“My land would have no value,” groundwater farmer Asier Artaechevarria testified, acknowledging that his operations rely 100 percent on groundwater withdrawals.

Ernie Myers, another farmer opposing the plan and who served on the Subdistrict 1 board for a several years, said it was after 2002, when the Upper Rio Grande Basin first experienced historic low flows from a lack of snow runoff, that he first began to feel targeted as a groundwater irrigator and had the feeling that surface water farmers were trying to put him out of business.

“I was pumping their water. I had no right to pump their water. I had a few farmers telling me, ‘I’m third, fourth generation. You’re a newcomer. You came in ’73 with your father. You have no right to do what you’re doing,’” Myers testified.

“And were there actually people saying that they intended to put you out of business?” a SWAG attorney asked.

“Yes, yes,” testified Myers.

Myers was the first to testify on behalf of SWAG and the Northeast Water Users Association. Knox was their final witness, and it was after his testimony that Gonzales made his interest in Rein testifying known.

“Common sense means a great deal to me,” the judge said.

Common sense tells the judge he should hear from the person who approved the plan he’s being asked to give legal approval to. 

The trial resumes Monday with the L Cross Ranch, another legal opponent to the plan, making its arguments before Gonzales.

July 14, 2026

Retired farmer Ernie Myers spoke Tuesday to the threats and hostilities he faced as a groundwater irrigator and how he felt like a “whipping boy” for surface water farmers who complained “that I was pumping their water.” 

Myers was the first to testify in protest of the Subdistrict 1 Fourth Amended Plan of Water Management as part of the Northeast Water Users Association and Sustainable Water Augmentation Group opposition to the plan.

He served on the Subdistrict 1 board of managers from 2012 to 2016 and told Division 3 Water Court Judge Michael Gonzales that “I was exhausted,” when he stepped down. “They beat me up mentally and financially.”

Myers and his family, along with Asier Artaechevarria, are asking Gonzales to reject the plan, which is designed to recover the unconfined aquifer through a one-for-one pumping mechanism — for every acre-foot of water pumped, an acre-foot of water must be returned to the aquifer — that limits pumping to the amount of natural surface water that comes into the subdistrict.

Groundwater irrigators with little or no natural surface water coming into their fields will have to offset their pumping either by purchasing surface water credits or paying a $500 per acre-foot fee, which Myers and Artaechevarria told the judge would put them out of business.

The plan has been approved by the Subdistrict 1 board of managers, the Rio Grande Water Conservation District board of directors, and the state engineer with the Colorado Division of Water Resources.

Artaechevarria told the court that he didn’t think enough had been done under the current plan of water management to try to make it work. Both Artaechevarria and Myers said they were willing to retire more acreage under the current plan and that the $500 acre-foot fee is beyond the economic means of groundwater irrigators.

“My land would have no value,” Artaechevarria testified, because he wouldn’t be able to market it for sale and wouldn’t be able to pay the mortgage as a result.

“You can see the issue there,” he told the court.

Myers said it was after 2002, when the Upper Rio Grande Basin first experienced historic low flows from a lack of snow runoff, that he first began to feel targeted as a groundwater irrigator and had the feeling that surface water farmers were trying to put him out of business.

“I was pumping their water. I had no right to pump their water. I had a few farmers telling me, ‘I’m third, fourth generation. You’re a newcomer. You came in ’73 with your father. You have no right to do what you’re doing.’”

“And were there actually people saying that they intended to put you out of business?” SWAG’s attorney asked.

“Yes, yes,” testified Myers.

The Division 3 water trial is in its third week at the Alamosa Judicial Center.

Costilla County, South Fork getting ahead of AI data centers: No projects have been proposed, but local governments increasingly want to make time to create land use codes that address data centers — Owen Woods (AlamosaCitizen.com) #SanLuisValley #RioGrande

July 15, 2026

Rumors of data centers have local government agencies in the San Luis Valley preparing for the inevitable – an application for a data center. 

Costilla County and the town of South Fork are the latest local governments to place moratoriums on artificial intelligence data centers. Though no applications or projects are being proposed, local governments want to give themselves time to create land use codes to address data centers. 

A packed room and a packed Zoom at the Costilla County Planning Commission meeting Wednesday morning saw tensions high as the public continues to express opposition to data centers. The commission approved a year-long moratorium. The moratorium will now go to county commissioners for approval. 

The town of South Fork’s planning and zoning board is poised to do the same thing during a public hearing Wednesday night’s planning and zoning commission meeting as the town does not have specific zoning regulations that address data centers. The board will use the public hearing for feedback as members begin their work over the next year to devise specific codes.

At Wednesday morning’s Costilla County meeting, planning commissioner Joseph Quintana dispelled rumors and reassured the public that a data center application has not been submitted to the county and that “nobody’s approved anything.” 

He said that when the planning commission was first formed the commission came up with a mission plan with a set of goals that were aimed at protecting the environment and the way of life. 

“A data center is the antithesis, the complete opposite of what we would want in this community,” he said.

He went on to say, “Our job here is to follow that mission that was established 30 years ago with public comment. So I just want to make sure everybody understands, nobody’s approved a data center that I’m aware of. Nobody’s even applied for a data center here. There’s nobody that’s asked to build one or tried to get a permit or anything like that.” 

In June, the Costilla County Commissioners asked the planning commission to address data centers “and get ahead before a problem develops,” Quintana said. 

Commissioner Frank Vigil said they wanted the year to create a “thoughtful” ordinance that “reflects the feelings of the general public.” 

“Our code doesn’t even have the two words ‘data center’ in it anywhere at all,” said county attorney Carle Turnetzer-Decker. “We were just concerned, I think, the board of county commissioners and the commission here, that if someone did approach us we have absolutely no way to handle it, restrict it, regulate it, do any of that.” 

In South Fork, the town’s board of trustees passed a year-long moratorium in June and added a definition for data centers and zoning determining for its municipal code. 

South Fork made a public statement on Tuesday that said, “To dispel rumors that are circulating within the community. The Town instituted a moratorium on Data Centers within the Town of South Fork last month which will last one year. The Town has not had any companies approach the town about data centers. We are simply trying to get ahead of any that may approach the Town. Obviously, there are concerns with them and rest assured your Board of Trustees share your concerns. Please come share your thoughts so we know how best to represent the community in making policy on this.” 

Saguache County was the first local government in the Valley to place a moratorium on data centers while it figures out how its land use codes would address any data center application. 

Earlier in June, the Rio Grande Basin Roundtable heard from Lindsay Rogers of Western Resources Advocates, who noted how rural markets are becoming targets for data center applications because of the assumption of “less red tape.”

Western Resources Advocates, Rogers said, has a particular interest working in the San Luis Valley as part of a grant process for local policy decision-making around large water users.

“One concern that we have which we’ve seen playing out in other states in our region, is that developers may target rural communities where they feel there may be less red tape to developing these data centers. Our communities may not have the time or resources needed to ensure the proposal fits within their own goals and their own resource availability. So we think it’s really important to think about these policy options proactively before developers come to town instead of responding to them once they’ve arrived.”

Richard Hubler, planning director for Alamosa County, said at the roundtable, “There’s a very real possibility, as we move forward, that because of our fiber networks here and our broadband capacity, our cheap land and what may end up being a glut of solar production that we could be a target in the Valley for somebody who says, ‘Hey, there’s more power than the Valley could use there. 

“I could take a circle next to that 600 megawatt project and use the other 400 megawatts they may have.’ And we don’t know how to handle that now as a county or as a Valley. I think that this is timely because we really do want to get ahead of it before we have to deal with an application.” 

In May, SLV Rural Electric Cooperative CEO Eric Eriksen said the Valley has underutilized energy capacity and that “rural data centers” are the “most relevant for us.” Rural data centers are described as smaller, more efficient facilities that are often housed within buildings no larger than small commercial buildings and operate anywhere from 50 kilowatts up to 50 megawatts.

These centers commonly use air-cooling or closed-loop refrigeration instead of consuming water.

These centers commonly use air-cooling or closed-loop refrigeration instead of consuming water. 

In SLVREC’s position, the agriculture’s energy demand is declining and that company sees “the underutilized capacity” as an opportunity “to serve five, 10, 20, 50 megawatts or more of rural data centers.” 

According to SLVREC, there are seven long-haul fiber routes into and out of the Valley, “with terabytes of unused capacity that is ideal for data centers.”

Trial vignette: ‘Biblical flood’ needed to recover aquifer: State engineer warns that without the new water management plan, wells could be shut off — Chris Lopez (AlamosaCitizen.com) #SanLuisValley #RioGrande

June 12, 2026

Some kind of “biblical flood” would have to occur over the next few years for the unconfined aquifer of the Upper Rio Grande Basin to recover, given the current downward measurements and the anticipated negative trajectory of the shallow aquifer’s storage area. That according to State Engineer Jason Ullman, whose testimony Friday wrapped up week 2 of the Subdistrict 1 Fourth Amended Plan of Water Management trial underway in Alamosa state Division 3 Water Court.

Ullman followed by telling the water court that without such a historical climate event, the current Subdistrict 1 Plan of Water Management is unlikely to meet its goal of reaching a sustainable aquifer by 2031, or five years from now and 20 years since the plan was first approved. 

His option over the next five years without a new plan of water management, he told Division 3 Water Court Judge Michael Gonzales, would be to not approve annual replacement plans, which is the mechanism groundwater well pumpers use for irrigation.

If annual replacement plans don’t get approved, wells cannot pump.

“I think I would say that it’s nearly impossible outside of some kind of biblical flood,” he testified of the current state of the unconfined storage area. “And even if that was to happen, there’s a limit to how much water can infiltrate into the aquifer on an annual basis or a monthly basis. So I don’t know that you can infiltrate enough water into the aquifer to reach that level by the 2031 deadline.”

According to monthly readings by Davis Engineering, the unconfined storage study area is measuring as low as it ever has since measurements by the consultant firm began in 1976, the court heard.

“In your opinion, will the current plan’s method of dry-up be able to achieve aquifer sustainability?” Rio Grande Water Conservation District lawyer Pete Ampe followed up with Ullman.

“No,” the state engineer told the water court. “I think it’s clear that based upon previous testimony that the goal in the previous plan was to reach 40,000 acres of dry-up that would’ve resulted or estimated to result in 80,000 acre-feet of reduction in use from the aquifer. And I think previous graphs showed that that has occurred, and yet we still see this precipitous decline. 

“I mean, I think some folks have talked about how it’s maybe leveled out some, but if you look here at the graph, if I was to plot a longer term or a longer than five-year average, I think you could agree that the trend is downward. It’s not upward, which is problematic when we have very limited time, five years to reach the sustainable water supply level defined in the current plan.”

The sustainable measurement definition is a five-year running average of water storage at negative-400,000 to negative-200,000 below surface and toward the 1976 readings.The current measurement, according to court exhibits, is 1.2 million acre-feet below and declining.

The state engineer’s office approved the fourth amended plan in June 20203, and it is the state engineer who would order widespread groundwater well curtailment. Gonzales must approve the new plan for it to move forward and Ullman to take that option off the table.

During testimony throughout week 2 of the subdistrict plan of water management trial, state Division 3 engineer Craig Cotten and state engineer Ullman testified to the limited amount of time left, without court approval of the updated plan, before wells are shut off.

“We have other impacts because of the lower aquifer supply that are occurring to other water users, to well owners,” Cotten told the water court. “As I’ve discussed, the amount of electricity costs that it takes to pump water out from a lower aquifer, the lowered efficiency of getting flood irrigation across a field, the impact to the environment from not having a water table at the near surface and potentially some ponds around. So lots of impacts. And I do think that we do need to recover the aquifer in a reasonable time period.”

The water trial is moving along speedier than anticipated during pre-trial conferences when Gonzales set the case to be over five weeks. William Schreüder, who created and maintains the Rio Grande Decision Support System Groundwater Model which is a key exhibit in the case, faced limited cross examination to his testimony, and Clinton Phillips, who maintains the unconfined aquifer storage area study for Davis Engineering and whose monthly storage graph provides key data for the state Division of Water Resources decisions, faced no cross examination.

One attorney, Mirko Kruse who is arguing his family’s specific concern around ditch decrees but overall supports to new plan, told the judge that in trying to be efficient with the court’s time he was prepared to make the very specific legal points to his client’s objections next week, if the judge wanted to hear those early.

The judge declined and said he preferred to hear all the expert witness testimony first.

There is little argument to the problem that the unconfined aquifer storage is declining due to groundwater withdrawals and the warming climate of the era, which is hugely problematic for any natural recovery through high elevation snow melt.

After two weeks, the arguments before Judge Gonzales center around surface and groundwater water rights, recharge decrees, and whether the fourth amended plan was crafted legally and openly and creates an economically fair playing field for all the irrigators in the subdistrict.

“Dr. Schreüder, what in your opinion does this all just come down to?” came the question from RGWCD attorney Pete Ampe toward the end of Friday.

“Well, your Honor, the basic premise of the fourth plan is that they will do one-for-one (pumping) which means we’re going to put more water into the aquifer than we’re going to take out and it’s common sense that under those conditions the aquifer should recover.”

The trial moves into week 3 on Monday, July 13, with State Engineer Ullmann still on the witness stand.

Attorney: ‘In order to evaluate the current state of the aquifer in context, you would need to know how much the aquifer holds, wouldn’t you?’

Engineer: ‘I don’t believe so’

How much water is in the storage area of the unconfined aquifer? That was a question SWAG attorney Brad Grasmick posed to state Division 3 Water Engineer Craig Cotten and left the Alamosa water court hanging on at the conclusion of Wednesday’s day in water court.

Grasmick represents the Sustainable Water Augmentation Group, farmers who operate in the subdistrict and have banded together to oppose the Fourth Amended Plan of Water Management which is the matter before Division 3 Water Court Judge Michael Gonzales. 

In his first full day of cross examining Cotten, Grasmick covered a variety of territory from surface water credits to the one-to-one pumping feature of the new plan to Cotten’s responsibility to administer the plan. At times he got so deep into the proverbial weeds in grilling Cotten that Gonzales spoke of his own frustration in trying to follow along.

“You’re losing me on focus,” Gonzales told Grasmick as he called for a lunch break.

The question Grasmick posed at the end of his nearly six hours of cross examination offered a unique exchange. Grasmick started by saying he hasn’t seen a figure on how much water the unconfined storage area can hold. It’s been well-established in the testimony of Cotten and HRS hydrologist Matt Seitz that the unconfined aquifer functions as an underground reservoir and was built up initially through early subirrigation practices and then canal diversions. 

Storage readings of the unconfined aquifer that go back to 1976 show it responsive to strong spring runoff seasons but now transitioning through the process of aridification to the San Luis Valley floor as it adapts to 25 years of drought and the lack of consistent snow melt.

“Nor have I seen how much water is presently in storage in the unconfined aquifer. Do you agree with that?” Grasmick asked.

Cotten: “Well, we have the Davis Engineering service change in storage, so we know the change in storage from 1976. The total amount of water in storage at the present time, I’m not aware of that number.”

Grasmick: “OK. In order to evaluate the current state of the aquifer in context, you would need to know how much the aquifer holds, wouldn’t you?”

Cotten: “I don’t believe so.”

Grasmick: “Well, and you would also need to know how much is in the aquifer in order to evaluate this decline in context, correct?”

Cotten: “No, I don’t believe so.”

Grasmick: “Well, as an example, if there was a one million acre-foot decline in storage, that’s very different if the reservoir holds one and a half million acre-feet than if it holds say four million acre-feet, isn’t it?”

Cotten: “There again, I don’t believe so if you’re shooting for an actual storage amount, change in storage amount as your goal.”

In the Fourth Amended Plan of Water Management under consideration, Subdistrict 1 is charged with recovering the unconfined aquifer to a “sustainable” level of negative-200,000 to negative-400,000 acre-feet of water storage.

Grasmick continued his questioning: “So you disagree that contextual analysis of data is necessary to ensure that it’s not misinterpreted?”

Cotten: “I don’t agree that we need to know the total storage or the actual storage right now in developing this plan.”

The exchange continued for about another three minutes before Grasmick began to shift to another subject and Gonzales intervened.

“I apologize. I think it’s been a long day, so I think it’s probably a good place to stop,” the judge said.

The water trial on the Subdistrict 1 Fourth Amended Plan of Water Management resumes Thursday [July 9. 2026].

July 4, 2026

The Colorado State Engineer’s office opened its defense this week of Subdistrict 1’s approved Fourth Amended Plan of Water Management with a history lesson on the origins of the San Luis Valley and the development of irrigated agriculture over the past 174 years when the first water right was issued to the San Luis People’s Ditch.

Featured in the state engineer’s defense was testimony by Matt Seitz of HRS Water Consultants, who took the state Division 3 Water Court through ancient history and into the era of early irrigation and storage practices of farmers in the Valley.

“Yeah, so we covered 25 million years pretty quickly, see how long the rest of it takes here,” he said from the witness stand Tuesday. Seitz stayed on the witness stand for the better part of the week, working to bolster to the state engineer’s defense of the Fourth Amended Plan of Water Management and then under cross-examination from a Sustainable Water Augmentation Group attorney, who worked to show faults in Seitz’ testimony and undermine the case of the state engineer in the eyes of Division 3 Water Court judge Michael Gonzales.

It is Gonzales who will decide this case. He will take in all the testimony around the various takes on the Fourth Amended Plan of Water Management to rule on whether the plan will be implemented. 

Plan of Water Management Equation

The subdistrict itself is charged with recovering the shallow unconfined aquifer of the Upper Rio Grande Basin and its Fourth Amended Plan of Water Management is the latest attempt to do so. The complexity of the basin’s hydrology has been an early theme.

“I think there’s been a lot of great research over the years,” Seitz said in speaking to the state’s modeling of groundwater in the Upper Rio Grande Basin and other studies on the Valley’s hydrology. “So I think we’ve made some good progress, but there’s a lot of complexity. Again, I’ve been saying that word a lot, but there certainly is and I think we’re on our way, but it’s never going to be fully understood.”

Week 1 of the trial ended with Craig Cotten taking the witness stand. He is witness number three for the state engineer’s defense of the plan, following Cleave Simpson, the general manager of the Rio Grande Water Conservation District who was the lead witness, and then Seitz, the hydrologist consultant who endured four days on the witness stand.

“Wonderful way to start the Fourth of July weekend,” quipped Gonzales as Cotten, the state water division engineer for the San Luis Valley area, stepped into the witness box at 1:50 p.m. on Thursday. He spent the initial two hours testifying to his background and his credentials before Gonzales broke for the Fourth of July weekend.

Cotten is the enforcer of the state’s groundwater management rules in the San Luis Valley. His testimony will reignite the trial when it resumes on Monday for week two of the water trial.

🐮 Grazing Gazette 🥩

Last month, U.S. Agriculture Department Undersecretary Michael Boren issued a memo, with a preamble by Agriculture Secretary Brooke Rollins, to Forest Service employees directing them on “advancing grazing on Forest Service” lands. It’s a curious, sometimes alarming memo. And, as is customary for the Trump administration, its authors are a bit confused about history.

While most public lands grazing occurs on Bureau of Land Management land, the memo reminds us that national forests also host more than 2 million cattle, sheep, and horses and burros. The current administration desperately wants more livestock on America’s forests, although it’s not clear why. 

The memo directs the agency’s staff to streamline the permitting process, to treat public lands1 ranchers with deference and respect, and to bring more “flexibility” to prairie dog “management,” which I assume means they want more efficient ways to kill the animals. It also guides line officers to offer up unallocated forage “to the maximum extent possible” and work to “solicit interest/applications from the eligible ranching community” to occupy vacant and closed grazing allotments. The goal? To add 500,000 head months2 of cattle and other livestock to national forest lands over the next two years, purportedly in part to “maintain the fabric of rural America.”

The fabric of rural America very well may be frayed, but throwing a bunch of half-ton methane dispensers onto drought-addled national forests to gobble up what grass and wildflowers remain in high-country meadows, trample stream banks, sully trout habitat, and make a mess out of trails, isn’t going to repair it.

Boren acknowledges that grazing on national forests has declined over the last 60 years in part due to “changing rangeland conditions” and “catastrophic wildfire and variable moisture levels.” But he seems oblivious to the fact that in most of the West, moisture levels remain at an all time low, and putting livestock on that land would not only lead to some pretty skinny cows, but also would further decimate the drought-stressed soils and vegetation.

Ranchers nationwide are actually thinning their herds due to drought and rising overhead costs, and cattle numbers are at record lows this year despite high beef prices. That reduces the chances that Boren will actually have many takers for the vacant allotments.

Still, it’s concerning. With the top brass pressuring the entire agency to pull out all of the stops to get more livestock on the forests, it’s not hard to imagine a district ranger succumbing and permitting a vacant allotment — even one that a conservation organization bought out from a willing rancher to help wildlife or reduce conflicts.

Rollins, meanwhile, seems confused about the origins of the agency she oversees. She writes:

But she doesn’t seem to consider what Congress was trying to “protect” the forests from, because in the next paragraph she writes: “From those early beginnings, grazing has been an integral part of our nation’s national forests …” Yeah, not quite. Let’s step back a bit, shall we?

During the early and mid-1800s, the United States stole, conquered, purchased, or acquired by treaty hundreds of millions of acres of land in the West and declared it the “public domain.” The government then went about “disposing” of the land, giving it away or selling it for virtually nothing via the Homestead Act, the General Mining Act, the Pacific Railway Act, the Desert Land Act, and so forth. By the end of the 1880s, huge tracts of public land had been handed over to the railroads, to mining interests, to states, and to homesteaders, yet across the West hundreds of millions of acres still remained in the public domain, and nearly all of those lands were open to unrestricted grazing, timber-cutting, and the devastation that came with them.

Gifford Pinchot would later describe the period like this:

Albert Potter, the USFS’s first chief of grazing, called the 1880s the era of “spoilation,” writing:

Unfettered livestock grazing wasn’t just diminishing the forage, but also wrecking watersheds. In southeastern Utah, the big livestock companies, notably the New Mexico and Kansas Land and Cattle Company, ran thousands of cattle and sheep across the once abundant grasslands on the slopes of the Abajo and La Sal Mountains, reducing them to denuded, dusty, gullied, flash-flood-prone wastelands. At one point, allegedly out of spite, the Carlisle livestock concern turned out thousands of sheep on the upper branches of Montezuma Creek, Monticello’s source for drinking water. Bacteria from the sheep feces contaminated the water, leading to a typhoid outbreak in Monticello that killed eleven people.

In hopes of mitigating the wreckage, in 1891 Congress passed the Forest Reserve Act, giving the president the authority to withdraw areas from the public domain3 as forest reserves, to be overseen by the Interior Department. Six years later Congress passed the Forest Management or Organic Administrative Act, which gave the previous law some teeth by providing a framework for managing the reserves. In 1905 President Theodore Roosevelt transferred management of the reserves to the Department of Agriculture and named the agency the Forest Service, appointing Gifford Pinchot as his chief forester.

Together, Pinchot and Roosevelt represented a major shift in the way the government managed and society perceived and treated the public lands. Roosevelt set aside some of the nation’s most cherished landmarks as national monuments. Pinchot believed that humans should utilize the forests and grasslands but that they should do so in a more sustainable manner so as to save some of the timber and forage for future generations. This conservationist ethos came to be known as Pinchotism, a term spit derogatorily by western politicians who were beholden to the extractive industries, such as Republican senator Weldon Heyburn from Idaho. Employing the same rhetoric that would later be used by the Sagebrush Rebels, Heyburn derided the forest reserve laws, suggesting that they amounted to theft of the “people’s forests.”

The question of livestock grazing on the forest lands was a contentious one for years. Under the Forest Reserve Act, grazing was effectively banned on the new reserves. After the Organic Act passed, the General Land Office began permitting grazing by cattle and horses, but not sheep — which were generally seen as far more destructive4— on the condition that it didn’t harm the forests. Eventually, Pinchot succumbed to the sheep industry lobby and grudgingly allowed grazing on some forests, causing a schism between him and John Muir, who was strongly opposed to sheep in forests.

Over the ensuing years, the Forest Service developed a grazing policy, permitting system, and set fees — very low ones — based on the number of animals, much to livestock operators’ dismay. This was in stark contrast to the lands in the public domain, where grazing remained a free-for-all until Congress passed the Taylor Grazing Act in 1934.

These minimal restraints, however, were not enough to stop the destruction. In the years following World War I, Forest Service officials found that grazing was still wreaking havoc on vegetation and spawning more erosion. Yet every time they tried to reduce the number of livestock on the land, they were hit with legal challenges, lobbying campaigns, and political pressure.

Ultimately the backlash to Pinchotism elevated Warren G. Harding, a friend to the industries that wanted free rein over the public lands, to the presidency. Harding chose Albert Bacon Fall to be his interior secretary, who immediately went about rolling back regulations and doing his best to erase the legacy left by Pinchot and Roosevelt, including opening up the public domain and Indian land to coal mining and oil and gas drilling. While Trump and his minions like to compare themselves to Teddy Roosevelt, in reality they much more closely resemble Harding and Fall.

A number of ferocious wildfires continue to rage across the Interior West. One of the largest is the Babylon Fire in Bears Ears National Monument, which had grown to over 81,000 acres as of Thursday night. It’s also on Forest Service land and is burning through some large, active grazing allotments, including the Babylon, Gooseberry, Twin Springs, and Cottonwood, and looks like it’s making its way onto some BLM allotments as well. 

The Gold Mountain Fire near Ouray, Colorado, had grown to about 21,000 acres, with the Ferris Fire near Dove Creek reaching nearly 29,000 acres. Fire weather is expected to continue through the weekend. 

🗺️ Messing with Maps 🧭

Note: On the occasion of America’s 250th birthday, I’m rerunning this piece from a couple of years ago on the July 1776 Escalante-Dominguez expedition that occurred even as the American Revolution was unfolding far to the east.

Don Bernardo Miera y Pacheco’s map, drawn following the 1776 Escalante-Dominguez expedition via The Land Desk

I’ve been fascinated by maps of all sorts for as long as I remember. Don Bernardo Miera y Pacheco’s map, drawn following the 1776 Escalante-Dominguez expedition, has intrigued me for nearly as long. And the more I look at old maps of the region, the more interesting this one becomes, in part because it’s far more accurate, especially in its depictions of the Four Corners Country, than maps made a century later by U.S. surveyors.

In July of 1776, Atanasio Dominguez and Silvestre Vélez de Escalante, a couple of Franciscan priests, headed out with a motley crew from Santa Fe in search of a route to California. Instead, they ended up going up what is now Colorado’s Western Slope and through the heart of Ute territory, across to the Great Salt Lake, dropping down through western Utah, and finally looping — somewhat erratically — back to Santa Fe. But if they didn’t find California, they did leave behind relatively detailed journals and maps that give us insight into what the region looked like prior to the Euro-American invasion, and into early European colonists’ perception of the region.

The party set out from the Pueblo of Santa Rosa de Abiquiu, on the first day of August, effectively leaving the Spanish Empire. The country beyond was the domain of the Weenuchiu, Tabeguache, Caputa, and Mouache bands of Ute. Not wanting to provoke the Ute people any more than necessary — they had made that mistake before — the Spanish Crown forbade settlers from wandering into the territory of or trading with the Utes.

Still, the path they followed was well-established. Juan Rivera had travelled it a decade earlier, and he had followed well-established routes through a land that had been inhabited for millennia, and that had been intimately mapped in the collective consciousness of oral histories. Rivera probably wasn’t even the first Spaniard to tread these paths; mavericks defied the travel and trade ban to acquire deerskins or to try their luck in the mineralized slopes of the high San Juan Mountains. The Spanish mavericks, in turn, were merely following paths already well trodden by Ute, Diné, Paiute, and Pueblo travelers long before.

So it shouldn’t be much of a surprise that current day routes more or less follow Escalante’s and Dominguez’s path. From Abiquiu the party traveled northwest, roughly following Hwy. 84 about to Los Ojos/Tierra Amarilla, which they described as:

This sort of assessment of a site’s suitability for a settlement is common in Escalante’s journals. Most places he deemed good for a village now have a village on them, from Arboles to Ignacio to Dolores to Hotchkiss, though none would be established for another century or more after Escalante’s journey.

They then cut westward, meeting up with the Navajo River near Dulce, which originates in what they called the Sierra de la Grulla, or the Mountains of the Cranes — now known as the South San Juans. Later they note that the headwaters of the Rio de Los Pinos are in the Sierra de la Plata, indicating that the entirety of what we now think of as the Western San Juans were then called the La Plata Mountains. When they reach the confluence with the San Juan River near Carracas, they write:

They called their camp “Nuestra Señora de las Nieves,” or Our Lady of the Snows, because they could see snow-capped peaks from there. This seems odd given that it was early August and they would have been looking at the south faces of the San Juans, where the snow should have melted months earlier. Maybe 1776 was a cold year, because later, they describe the passage between Durango and Hesperus like this: “the terrain is very moist, since it rains very frequently because of its proximity to the Sierra; as a result, both in the mountain forest — which consist of very tall and straight pines, scrub oak, and several kinds of wild fruits — and in its narrow valleys there are the prettiest of pastures. The climate here is excessively cold even in the months of July and August.”

On this version of the map, Miera did not include the route of the expedition. But the little circles with crosses indicate places they stopped, camped, or named. Via The Land Desk

They make it to the Big Bend of the Dolores River and then do some bending of their own, deviating from their westward course by 90 degrees for reasons I can’t figure out. Were their guides trying to avoid the rugged Canyon Country of southern Utah? Were they blindly following the path of their predecessor, Rivera? For whatever reason, they ended up heading north, encountering the Dolores River a second time near Cahone and a third time near Slick Rock.

The party tried to follow the Dolores River downstream (north), but was stymied by the narrow, twisty gorge, writing: “The canyon we named El Laberinto de Miera because of the varied and pleasing scenery of rock cliffs which it has on either side and which, for being so lofty and craggy at the turns, makes the exit seem all the more difficult the farther one advances.” They turned eastward into the Big Gypsum valley, then toward Naturita and Nucla, before crossing the Uncompahgre Plateau where they found “deer and roe and other animals breed, and certain chicken fowl the size and shape of the common domestic ones, from which they differ in not having combs. Their flesh is very tasty.”

They dropped down to what they call the El Rio de San Francisco north of Montrose and that the “Yutas” call Ancapagri — i.e. Uncompahgre — or “Red Lake”, “because they say that near its source there is a spring of red-colored water, hot and ill-tasting.”

It seems that part of the reason Miera’s maps somewhat accurately depict areas the party never journeyed to is because they spoke with the Indigenous people who intimately knew the country. This is in sharp contrast to U.S. maps drawn a century later, which depict much of southeastern Utah as a big blank spot, with the San Juan River vanishing into the desert after passing the Four Corners. Miera y Pacheco’s map, meanwhile, accurately shows the stream meeting up with the Colorado in Glen Canyon.

That said, Miera y Pacheco does make some errors. He has the Gunnison River (San Xavier) running into the Dolores River near the present site of Gateway (passing through the Unaweap Gorge, perhaps?), and his maps appear to have the Green River (Rio San Buenaventura) flowing through the Wasatch Range and into Utah Lake.

Miera’s depiction of the Great Salt Lake and Utah Lake. Via The Land Desk

At Montrose the party again took an odd route, going up the Gunnison River, in a northeasterly direction, rather than following it downstream to the northwest, up and over Sierra del Venado Alazan (Mountain of the Sorrel-Colored Deer), or Grand Mesa, before getting back on course (sort of) and making their way to the Great Salt Lake. It wasn’t until that point, when winter was starting to set in, that they realized maybe they should have taken a different route, and that Monterey, their final destination, was still a long ways off.

From the Great Salt Lake, the expedition went southward, roughly following I-15, before cutting east at St. George and encountering the Colorado River where it passes through the Marble Gorge. As you might imagine, crossing the river and the canyon wasn’t easy. Via The Land Desk

So they went south, all the way down to St. George, before turning back to the east, Santa Fe-bound. This is where it gets interesting, because their guides were not familiar with the country (what we would now call the Arizona strip) they were headed for. And yet, even though their route-finding was sometimes determined by drawing lots, they somehow managed to encounter the Colorado River at one of the few places they could get down to it, just downstream from the Paria River. Crossing the river, itself, wasn’t so easy.

So they built a raft of logs, and “Father Fray Silvestre, accompanied by the servants, tried to cross the river; but although the poles they used to propel it were about five yards long, they did not touch bottom even a short distance from the bank.”

It was late October by then and, “Not knowing when we would be able to leave this place, and having already eaten up the meat of the first horse, the pine kernels and the other provisions we had bought, we ordered another horse killed.” Desperate, they hiked up the Paria until they were able to climb up to the plateau, then dropped back down to the Colorado River in Glen Canyon in a place they called San Diego. Finally they found a place where the canyon and river widened — now inundated by Lake Powell — and they were able to cross. After climbing out of the canyon: “We found today many Indian tracks, but saw no one. So many wild sheep flourish here that their tracks look like great herds of domestic sheep. They are smaller than the domestic variety, of the same shape but much swifter.”

The party finally reached Santa Fe and in the ensuing years Miera y Pacheco created at least two maps of the country they had traveled through.


1 When I use the term “public lands” I’m referring not only to BLM lands, but also to national forests, national parks and monuments, and national wildlife refuges.

2 Head Month is the U.S. Forest Service term for a cow-calf pair eating public forage for one month. It’s similar to an Animal Unit Month on BLM land.

3 When land is “withdrawn” from the public domain, it simply means that it is no longer available for “disposal.” That is, it can’t be privatized via homesteads or mining claims.

June 29, 2026

Rio Grande Water Conservation District General Manager Cleave Simpson testified it’s not a foregone conclusion that groundwater irrigators would pay the $500 per acre-foot fee for overpumping but have other options under the Fourth Amended Plan of Water Management for Subdistrict 1.

Simpson was the first to take the witness stand Monday in a state water trial that will determine if the Subdistrict 1 plan will go into effect. The plan, which calls for Subdistrict 1’s groundwater withdrawals not to exceed the amount of natural surface water that comes into the Upper Rio Grande Basin, has been approved by the state engineer and now is being tested in state water court.

Opponents to the plan argue the state engineer’s review was not thorough, did not follow Colorado water law and should not be allowed to go into effect. Other opponents have more nuanced arguments around surface water credits.

The linchpin to the subdistrict’s Fourth Amended Plan of Water Management is the overpumping fee, which some farmers and ranchers argue will put them out of business. Simpson testified that groundwater irrigators can purchase surface water credits from neighboring operations or submit their own plan of augmentation for approval from the state without incurring the subdistrict’s overpumping fee.

A 2018 letter sent by then-State Engineer Kevin Rein that warned of mass groundwater curtailment without progress on the unconfined aquifer “created a heightened sense of urgency,” within the Rio Grande Water Conservation District and Subdistrict 1, Simpson testified.

The federal government’s voluntary Conservation Reserve Enhancement Program became one program the water conservation district shifted into to reduce the amount of productive acres farmed. A Fourth Plan of Water Management for Subdistrict 1 became another, Simpson said.

The water trial comes three and a half years after the subdistrict water management plan was adopted by Simpson’s Rio Grande Water Conservation District board. The effort is tied to recovering the unconfined aquifer of the Upper Rio Grande Basin and restoring it to sustainable levels.

A group of subdistrict irrigators organized under the Northeast Water Users Association and Sustainable Water Augmentation Group are opposing the plan. They irrigate on 11,000 acres in the Center area. Also in opposition are owners of the L Cross Ranch, who rely on La Garita Creek and Carnero Creek as water sources in addition to their own groundwater pumping.

The trial will continue through July.

June 26, 2026

The most significant water trial the San Luis Valley has ever seen opens this Monday morning in Courtroom A of the Alamosa County Judicial Center. At stake is the Fourth Amended Plan of Water Management for Subdistrict 1 of the Rio Grande Water Conservation District, which calls for a dramatic shift designed to match the amount of groundwater pumping to the amount of natural surface coming into the subdistrict. 

Producers in Subdistrict 1 are under pressure to recover the unconfined aquifer of the Upper Rio Grande Basin, but so far the subdistrict has made little to no progress in creating a sustainable aquifer. The trial is scheduled for five weeks before Colorado Water Court Division 3 Judge Michael Gonzales.

The San Luis Valley’s highly-anticipated district water court case — the water trial of this century if you will — was originally scheduled to last five weeks beginning in January. It was pushed back six months to this summer due to the departure of a key witness in the fallout from a series of contentious October emails.

The Fourth Amended Plan of Water Management by Subdistrict 1 in the Rio Grande Water Conservation District has lived a precarious life without ever being implemented, going back to 2022 when it was originally crafted by subdistrict managers and January 2023 when it was adopted by Rio Grande Water Conservation District board.

Later came approval by the state engineer, and then after objections were filed against the new amended plan, Colorado Water Court Division 3 Judge Michael Gonzales set a trial date to commence on Jan. 5, 2026, and to last five weeks.

That is, until the week before Thanksgiving when Gonzales scrapped the January date in favor of June 29, 2026, some four years after the plan was first approved at the subdistrict level and the unconfined aquifer still in a historic decline. The judge did so after a series of emails sent by a key expert witness for the main objectors to the plan surfaced.

The effect is that a new plan to recover the Rio Grande’s unconfined aquifer, which has been approved at the local and state levels but still requires sign-off from district water court, remains  in limbo.

Following filings by the Northeast Water Users Association and Sustainable Water Augmentation Group requesting a six-month continuance to the start of the trial, and the Rio Grande Water Conservation District and state Division of Water Resources objecting to the request, Gonzales ruled the two main objectors challenging the new aquifer recovery plan had good reason to ask for a six-month continuance after Taylor Adams, an environmental and water resources engineer for Hydros Consulting in Boulder, resigned from the case due to “personal and family circumstances.” 

Adams was set to challenge the Subdistrict 1 water plan on a variety of engineering fronts until a series of emails he sent in October to State Engineer Jason Ullman and Senior Assistant Attorney General Preston Hartmann came to light. In one email, he tells Ullman, “Also, GFY.” In another, he emails that he is “no longer interested in anything other than publicly exploding the rampant corruption at DWR and the AG Office.” 

And in an email sent Sunday, Oct. 19, to Attorney General Phil Weiser, Adams writes, “We haven’t met, but I understand that you’re running for governor of Colorado. You should know that if you continue this pursuit without addressing the persistent and laughable perjury that has been carried out in your name by Preston Hatman (sic) and Jason Ullman, you will be the subject of my attention throughout your campaign…”

The Rio Grande Water Conservation District asked Gonzales not to delay the water court proceedings due to the urgency to recover the unconfined aquifer and the lack of “credible evidence that demonstrates that Mr. Adams is unavailable. Rather, they now assert that he ‘should not be pressured into returning to the case at the risk of further harm to his mental health.’”

“In any event,” district water attorneys argued in their objection to a trial delay, “none of this changes the fact that the unconfined aquifer is still over 1.3 million acre-feet below the water levels measured in 1976, and more than 830,000 acre-feet below the water levels previously determined by this Court and the Colorado Supreme Court to be sustainable.”

Subdistrict 1 is home to the San Luis Valley’s richest crops of potatoes, barley and alfalfa. Without recovery of the shallow aquifer, the state is threatening mass shut down of groundwater pumping wells and requires both a master plan and annual replacement plans to show recovery efforts.

The subdistrict’s proposed Fourth Plan of Water Management is its most drastic effort yet to meet the state’s orders. The new plan, crafted in 2022 and adopted by the Rio Grande Water Conservation District in January 2023, is designed to “match the amount of groundwater pumping to the amount of water coming into the subdistrict.”

It does this through a 1-to-1 augmentation, meaning for every acre-foot of water used, an acre-foot has to be returned to the unconfined aquifer through recharging ponds. The amended plan relies on covering any groundwater withdrawals with natural surface water or the purchase of surface water credits.

Farmers in the subdistrict have expressed support for the plan, which includes a $500 per acre-foot overpumping fee that farmers would pay if they exceed the amount of natural surface water tied to the property in their farming operations. 

Objections are coming from farmers who do not have natural surface water coming into their property and around the steep fee for purchasing surface water credits from a neighboring operation to offset groundwater pumping irrigation. Both proponents and opponents of the plan say the $500 per acre-foot overpumping fee could put farmers who rely on groundwater pumping out of business.

The five-week water trial will sort through these issues in much more granular detail. Any new strategy to recover the Valley’s ailing aquifer will shift into 2027 at the soonest.

US Supreme Court settles long-running water dispute over dwindling #RioGrande — The Associated Press

May 27, 2026

In a brief order Tuesday, the court accepted the recommendation of a special master to move forward with agreements first proposed last year by New Mexico, Texas and Colorado. The settlement calls for reducing groundwater pumping along the dwindling river and retiring water rights from irrigated farmland in southern New Mexico. The states held up the proposal as a promise to restore order to an elaborate system of storing and sharing water between two vast irrigation districts in southern New Mexico and western Texas. 

“We’re very excited to be redirecting resources from costly and lengthy litigation to solutions on the ground,” Hanna Riseley-White, director of the Interstate Stream Commission, said Wednesday…

Those solutions will include everything from long-term fallowing programs and more efficient irrigation infrastructure to developing new sources of water, like tapping brackish supplies or importing water, and improving stormwater management so more runoff can be captured and stored.

As a #Colorado Aquifer Runs Low, Dangerous Heavy Metals Threaten Rural Communities’ Drinking Water — Emily Payne (InsideClimateNews.org) #SanLuisValley #RioGrande

May 8, 2026

In the San Luis Valley, the ongoing megadrought and a record-low snowpack are draining groundwater and increasing its concentrations of toxic metals. There are few protections for residents drinking from private wells.

Julie Zahringer hears a common refrain at her environmental laboratory in Alamosa, Colorado: A customer has been drinking well water on family land where they’ve lived for years, but recently noticed it has changed. They want to know why.

“All of a sudden it looks different, tastes different, there’s odor, there’s color,” said Zahringer.

Zahringer’s SDC Laboratory is one of the few testing water in the San Luis Valley, an 8,000-square-mile, high-altitude desert in south-central Colorado. She has tested thousands of wells during more than 30 years in the field.

Residents of the valley, which has large Hispanic populations and a high poverty rate, have been concerned about naturally occurring heavy metals in their water for decades, she said. But in the past five years, the rate of change has accelerated.

“Every year it just seems like this is the climax of it, and the next year, it gets worse,” said Zahringer. “This year, we’re looking at probably the worst as far as water quality.”

San Luis Valley Groundwater

The San Luis Valley relies on surface water from the Rio Grande and a massive aquifer system, one of the largest in North America, to drive its agricultural economy. But the aquifer is severely overallocated, losing an estimated 1.2 million acre-feet of water between 1976, when tracking began, and 2013—equivalent to more than five times what the city of Denver consumes each year. This year, the aquifer could hit another record low, as Colorado’s snowpack, which recharges the state’s aquifers, is at the lowest level since record-keeping began in 1941.

Researchers are finding that as groundwater levels drop, the remaining water can contain higher concentrations of carcinogenic heavy metals.

The valley’s well water users, many of them in historically underserved communities, are increasingly concerned about what’s in their drinking water. But with little governmental oversight of private wells or resources to help track and manage quality, they have few options to make it safe.

Shifting Chemistry 

Anna Vargas, a sixth-generation resident of the San Luis Valley, remembers making snowmen often as a child, and her mother talking about the daily rains during the summer monsoon season. Now, monsoon season barely exists here, Vargas said.

“As the years have gone by, there’s less rain, less snowfall. I’ve lived in the valley long enough to see the changes in weather patterns,” says Vargas, project manager with the SLV Ecosystem Council. “We depend a lot on snowpack, and we have hardly any this year. It’s concerning for all of us in the Rio Grande basin…The heavy metals will just become more concentrated.” 

Map of the San Luis Valley

Heavy metals like arsenic, tungsten, uranium, manganese and selenium occur naturally in rocks and soils and come up with groundwater that is pumped to the surface. With drought, Zahringer said, they can become a problem.

“We’re not seeing a dilution of any of the contaminants…so anything that’s in the geologic makeup is just really concentrating,” said Zahringer, whose tests have documented contaminant levels rising in the wells during dry periods.

In addition, as aquifer levels drop during droughts—and due to overpumping—its geochemistry shifts, says Kathy James, Ph.D., associate professor with the Colorado School of Public Health. Users reaching deeper into the ground to access the remaining water can draw small amounts of water connected to geothermal sources or underground reservoirs of hot water, which can have high arsenic concentrations, into the drinking supply. Even in small amounts, this can increase arsenic concentrations to dangerous levels. James notes that these relationships are complex and non-linear, however, and additional research is needed.

This year, James led a study finding that up to one in four private wells producing drinking water in the San Luis Valley contain elevated levels of heavy metals like arsenic and uranium.

Zahringer’s estimates mirror these results: Of all the well waters her lab tests in southern Colorado, about 25 percent exceed the U.S. Environmental Protection Agency’s maximum contaminant level for arsenic in drinking water

And “that’s just going up,” Zahringer said.

Unanswered Questions

Exposure to arsenic in drinking water is linked to cancer, cardiovascular disease and diabetes, and can impair children’s cognitive development. James’s previous research also found that long-term exposure to low levels of arsenic can increase the risk of coronary heart disease.

Other studies have shown that both uranium and arsenic in irrigation water can stunt crop growth and accumulate in plants, compounding public health risk through the food supply.

Zahringer said that some customers come to her lab on referrals from their primary care physicians trying to determine the root cause of elevated levels of heavy metals in their bloodstream. Her own well water is high in arsenic, but her filtration system thoroughly treats it before it enters her house.

“I’m in a unique situation where I’m educated and vigilant, and I have the resources to test and make sure it’s OK,” said Zahringer. “A lot of my neighbors, I know they’re just drinking it right out of the ground.”

Half of the U.S. population relies on groundwater for drinking, irrigation, industry and livestock. Much of it is pumped through public water systems, which must limit contaminants to comply with the federal Safe Drinking Water Act, in addition to state requirements that may be more stringent. But private wells, which are the main source of drinking water for 15 percent of Americans and about a third of San Luis Valley residents, are not regulated or monitored. In effect, about 51 million Americans are responsible for monitoring the safety of their own drinking water.

In the San Luis Valley, residents are asking more questions about how their water is impacting their health, crops and cattle, Vargas said, making it easy for her to recruit some of the more than 800 private well owners involved in James’s study. 

“We filled it up so fast that that just shows how much the community members wanted their wells tested,” says Vargas.

After a few months of recruiting, the study group was nearly at capacity.

Later, neighbors would stop her at the grocery store to tell her about their results: manganese, arsenic, uranium or other contaminants were often above the EPA thresholds. 

Today, many residents in Vargas’s community have turned to bottled water. “They just don’t know if they can drink the water,” she said.

Climate Justice

With the ongoing megadrought and this year’s record-low snowpack in Colorado, small communities, private well owners and municipal water systems alike will struggle to keep up with changing groundwater supply, Zahringer said. Researchers estimate that U.S. drought conditions could expose roughly 1 in 10 well-water users to unsafe arsenic levels.

“As those contaminants are increasing, we are going to start to see these rural areas really can’t afford these treatment plants and mitigation for it,” said Zahringer. “We’re dealing with a lot of really small communities that are really struggling to pay for their water testing, let alone to build these new plants.”

San Luis Valley is one of the poorest rural areas of Colorado, with an estimated 21.4 percent poverty rate. Even if well users can access a water test, consistent filtration remains an economic burden.

Household reverse osmosis systems can remove up to 99 percent of contaminants, including arsenic. But they are expensive—often costing thousands of dollars to install and hundreds more annually to maintain—and can waste up to 80 percent of the water that passes through them. And because the San Luis Valley has moderately to extremely hard water, compounds and metals accumulate much faster on filtration systems, requiring replacement more than twice as frequently as in areas with soft water. 

“I come from a rural and impoverished community, and my community members can’t always be changing out these filters for this reverse osmosis filtration system,” Vargas said.

Researchers at Arizona State University are planning to field test a new type of filter that removes a range of heavy metals from hard water systems without losing water in hopes of providing more accessible water quality mitigation for residents. Alireza Farsad, a postdoctoral research scholar at ASU who founded AmorPH2O, the company developing the filter, expects it to be commercially available next year.

Meanwhile, Vargas and James have presented the water quality study results to local county commissioners and talked with state lawmakers about the increasing concentrations of heavy metals. 

But, for now, the issue has seen little action beyond testing.

For Shirley Romero Otero, a local educator and activist who helped implement James’s study, water quality in the San Luis Valley is an issue of environmental justice. She says the valley, home to the state’s largest native Hispanic population, is often left out of policymaking conversations.

“Those folks in Denver that make those decisions for testing and resources need to pay attention…We are part of Colorado. We should have equality when it comes to testing and finding out what the hell is really going on,” says Otero, who lives in San Luis, the state’s oldest continuously occupied town, which has fewer than 600 residents.

“Regardless of socioeconomic status, political affiliation or racial geographic areas, water is the most precious resource that we have. It is the lifeblood of every community. You don’t have water, you die. It’s that simple.”

Saguache County places moratorium on data center projects: County Commissioners want time to determine land use regulations for any rural data center projects — Owen Woods (AlamosaCitizen.com) #RioGrande #SanLuisValley

May 8, 2026

Saguache County adopted a resolution on Tuesday, May 5, 2026 that placed an emergency temporary moratorium on any data center projects within the county for six months. 

Some language was changed in the draft resolution during the meeting, but the commissioners said the resolution was drafted following their April 21 meeting where San Luis Valley Rural Electric Cooperative CEO Eric Eriksen said that the power company had received three inquiries for “rural data center” projects in the Valley. 

A representative with SLVREC said Eriksen was out of the office this week, so a voicemail was left with him on Tuesday morning. 

Alamosa County Administrator Roni Wisdom sent the Citizen a copy of SLVREC’s informational newsletter that breaks down what a “rural data center” is. In that letter given to the Alamosa County Commissioners, Eriksen said that over the past year, SLVREC “have been in discussion with three rural data center developers exploring opportunities.” 

The Saguache County moratorium is necessary “for the immediate preservation and protection of the public health, safety, and welfare of the citizens of Saguache County.” 

“Everybody in our county is upset about data centers,” said Saguache County Commissioner Liza Marron.  

The primary purpose for enacting an emergency temporary moratorium on the acceptance, processing, or approval of data center projects is “to provide the County sufficient time” to develop and amend the Saguache County Land Use Code, Standards, other sections of the Land Use Code, and Saguache County 1041 Regulations.

Any changes to the land use code requires a review and recommendation by the County Planning Commission and a public hearing. 

“The intent of the new Land Use Code and 1041 provisions prepared and implemented during the moratorium period is to establish an improved process and standards regarding requests for Data Center projects,” the resolution reads. 

“County Land Use Department has informed the BOCC that it has received inquiries regarding data center projects and the current regulations in the Land Use Code,” the original draft read. This turned out not to be the case. 

Saguache Land Use Administrator Amber Wilson said her office has not had any official inquiries for data centers. “No one has come to us,” she said. 

The language in the paragraph of the moratorium had been changed on May 5 to reflect the information stemming from SLVREC. 

The Saguache County commissioners can put the moratorium in place for the purposes of “prohibiting or regulating in any part of or all of the unincorporated territory of the county used or to be used for any business, residential, industrial or commercial purpose….” 

Meanwhile in Alamosa County, Land Use and Building Director Richard Hubler told the Citizen, “we have not received any applications for data centers, although I’ve had a couple questions about them, including a call from someone related to this small scalecontainer based project”

Hubler said that Alamosa County doesn’t currently have anything specific codes to address data centers, but he said the county is currently “talking about updates that would likely end up with some new language about stand-alone data centers as a primary use, and something related to size.” 

“Certainly the Hyperscale centers like the Front Range are seeing could have a huge impact on housing and energy needs,” Hubler said, “in addition to water. But the smaller ones like that container may be a good fit for existing capacity on the SLVREC system.”

He noted there are some small data centers that assist agriculture operations and also the local hospital system. 

“We even have server rooms at the county buildings, but these are all ancillary to the principal use, not developed for commercial sale/rental applications, and are not as much part of the current ‘data center’ conversation which focuses heavily on AI.” 

This map shows the current data centers, their power usage and location. Though it has yet to be built yet, the BlueSky AI project in Huerfano County is already on the map. 

“Our high altitude cool sunshine air, your SLV Rural Electric Cooperative and Ciello broadband are perhaps the most ideal conditions in the nation for a rural data center,” Eriksen wrote. “That gives us a competitive advantage.” 

Eriksen wrote mainly about the economic and technological benefits of a data center in rural areas. 

“Not all data centers are the same,” he wrote. “Not every data center is a giant, power-hungry, watering-guzzling complex like the ones you see in national news.” 

He compared the different types of data centers: Hyperscale data centers, regional data centers, and edge or rural data centers. Hyperscale data centers require 100 megawatts of power or more and thousands of square feet. Regional data centers are described as mid-sized facilities that require strong infrastructure, but are often operating on less than 100 megawatts. 

The rural data centers, Eriksen said, “are the most relevant for us… Rural data centers are small, efficient facilities — often the size of a modular 20’ or 40’ metal container, a home or a small commercial building.” 

He wrote that SLVREC’s largest “electric member” is about 1.5 megawatts. 

These data centers, Eriksen wrote, require far less power than hyperscale data centers, operating at 50 kilowatts up to 50 megawatts. These centers are said to commonly use air-cooling or closed-loop refrigeration instead of consuming water. 

In SLVREC’s position, the agriculture industry’s energy demand “has been declining.” The company sees the “underutilized capacity” as an opportunity “to serve five, 10, 20, 50 megawatts or more of rural data centers.” 

According to SLVREC, there are seven long-haul fiber routes into and out of the Valley, “with terabytes of unused capacity that is ideal for data centers.”

Eriksen said that reducing the “digital distance” between the San Luis Valley “and the rest of the world is transformational. When data is processed closer to home, everything works better and faster. Rural data centers can help lower rates.” 

Those three developers that SLVREC has been in communication with “haven’t pulled the trigger yet, but if one does, then you’ll know it’ll be beneficial for all of us,” wrote Eriksen.

Paper: Rethinking How the United States and Mexico Share the #ColoradoRiver — Eric Kuhn, Anne Castle, Carlos de la Parra, John Fleck, Jack Schmidt, Kathryn Sorensen, Katherine Tara #COriver #aridification

March 26, 2026

Since 1945, the United States and Mexico have managed common interests on their two largest shared rivers systems, the Colorado and the Rio Bravo/Rio Grande, under the terms of the 1944 international treaty that was designed from the beginning with tools to adapt to changing hydrologic and societal conditions.

A recent emergency agreement on the Rio Bravo/Rio Grande illustrates what is possible, and with old river management rules on the Colorado both within the United States and between the United States and Mexico about to expire, we are at a moment of opportunity for meaningful change.

The core problem on the Colorado River, which we address in the analysis that follows, arose from decisions made in the first half of the 20th century to allocate fixed volumes of water. As usage patterns and hydrology change in the 21st century, fixed volumes no longer work. A shift to a percentage-based split between the United States and Mexico on the Colorado River, based on the river’s actual natural flow, would provide a solid foundation for the two countries’ joint management of the Colorado in the decades to come.

‘Historic’ agreement between NM land grant and Forest Service to revitalize 200-year-old acequia: Santa Fe National Forest agreement ‘a great leap forward’ after century of tension, New Mexico lawmaker says — Patrick Lohman (SourceNM.com) #RioGrande

May 5, 2026

A dusty acequia in northern New Mexico, which more than 200 years ago diverted water from the Rio Chama, will soon spring to life again, nourishing freshly planted orchards of plums, apples and apricots.

That’s the idyllic scene envisioned through a new agreement between the Santa Fe National Forest and heirs of the San Joaquín del Rio de Chama Land Grant. The parties say the “memorandum of understanding” they signed in late March marks the potential thawing of more than a century of tension between New Mexico land grants and the federal government. 

The agreement, which the Santa Fe National Forest Service provided to Source NM through a public records request, identifies the acequia restoration as a “project of mutual interest.” It also recognizes the land grant as a consulting partner to the Forest Service and provides it greater input into the land’s future use. 

Leonard Martinez, president of the land grant, told Source NM that the nine-page agreement is a “historic document,” one that marks the first such formal agreement between land grants and the Forest Service. He said he’s spent nearly every day since the agreement was signed clearing the historic irrigation canal and working to reconnect it to the Rio Chama.

If all goes well, he will open the headgates of the Acequia Madre de Cañon de Chama later this summer, sending Chama River water to irrigate a cover crop of alfalfa. Within five years, he hopes to replant historic orchards.

When that happens, he said, he hopes the “heirs who have left us,” many of them still buried in a cemetery near the headgates, will approve of his efforts. 

“That’s the key here,” he said. “We want to put our orchards and our fields back in.”

Santa Fe National Forest spokesperson Claudia Brookshire told Source NM that the agreement resulted from trust established through informal talks and individual projects. 

“The Forest Service has long been willing to work with land grants,” Brookshire said in an email. “But the lack of a formal framework, combined with trust barriers, made it difficult to begin projects on national forest system lands.”

The Santa Fe National Forest is in early discussions to develop similar agreements with two other land grants, Brookshire said.

In 1806, Spanish Governor Joaquín del Real Alencaster charged 44 families with stewardship of a 470,000-acre swath of what was then the New Mexico Territory. By 1860, according to the land grant, more than 800 residents established roots there, cultivating land within the river valleys, pasturing livestock and gathering resources from the surrounding common lands, known as the “ejido.” 

But after multiple lawsuits and land re-surveys over the ensuing decades, the federal government and land speculators acquired the land and evicted the residents. By 1905, the federal government recognized only about 1,500 acres of land along the Rio Chama as belonging to the land grant, but even that parcel ended up in the hands of the Rio Arriba Land and Cattle Company. 

The parcel west of Abiquíu, known as the Cañon de Chama, remained the company’s property for decades before the federal government ultimately acquired it, as well. Today, all of the original San Joaquín del Rio de Chama Land Grant belongs to the Santa Fe National Forest or Carson National Forest.

Land grant heirs like Martinez have fought for more than a century to reassert their rights over the land, including seeking Forest Service permission to visit and care for the cemetery where their ancestors are buried. 

The heirs ultimately received a Forest Service easement in 2013 to access the cemetery. Since then, Martinez and other land grant leaders have continued to pressure the Forest Service for more access, particularly to the Cañon de Chama, which heirs describe as culturally and historically significant. 

Martinez told Source NM that the agreement is a result of trust built through the cemetery easement, he said, as well as guidance from the New Mexico Department of Justice’s Treaty of Guadalupe Hidalgo Division.

The NMDOJ created the division in 2003 to oversee and address concerns related to the provisions of the 1848 Treaty of Guadalupe Hidalgo, which ushered in the United States’ government’s problematic land title confirmation process and stripped the San Joaquin land grant heirs of hundreds of thousands of acres of communal land. 

New Mexico Rep. Miguel Garcia (D-Albuquerque) has spent much of his 30 years in office advocating for land grant heirs, including seeking recurring state funding and greater recognition of the historical injustice of the federal government’s land seizure. 

While he said the new agreement represents a “great leap forward” and commended Martinez and others for their efforts, he said his ultimate goal remains for the Forest Service to return land it now controls to the land grants.”

“These land grants that lost these common lands have not ceded their right to that land,” he said. “They have not given up that hope.”

April 21, 2026

As the Rio Grande dries out months early, water managers look to blessings, prayers and groundwater to save the acequias that have spread water, history and culture to farmers and families since the 16th century.

On a sunny spring morning at the end of March, a woman raised her little girl above an irrigation ditch that runs just west of the Rio Grande in Albuquerque’s South Valley. The toddler, with a braided head piece crowning her long, brown hair and artificial flowers around her neck, enthusiastically tossed an assortment of colored petals into the water below as a small crowd cheered. 

It was part of a blessing ceremony at the headwaters of the Atrisco Acequia Madre (Atrisco Mother Ditch)—considered to be the oldest and most important of these irrigation canals in the area—during “Primera Agua,” an annual celebration that commemorates the first water flow of the season.

The day, sponsored by the Center for Social Sustainable Systems (CESSOS), a local advocacy group, was filled with traditional dances, songs, chants, blessings and speeches about community. But it also included acknowledgments of the water challenges that New Mexico faces.

This year, New Mexicans are confronting record-low snowpack, which is essential for supplying an even flow of water into acequia systems. Record heat isn’t helping, as it accelerates evaporation throughout New Mexico waterways and has contributed to an early melt off of the already thin snowpack. 

At the March 29 Primera Agua event, temperatures were 14 degrees Fahrenheit above average in Albuquerque, and about a week earlier, the city set a record for the earliest 90-degree day of the year. Like much of the West, the city also experienced its warmest winter on record. 

“Every year seems like it’s a new bar in terms of the record low,” Paul Tashjian, director of freshwater conservation for Audubon Southwest, said of the low water levels that were already hitting the state in late March. “But this year is almost like that on steroids…It’s not a pretty picture.”

“It’s in Your Blood”

New Mexico’s acequias date back to the late 16th century, when the Spanish colonized the region. By 1700, what would become New Mexico had around 60 of these community-managed irrigation ditches. Today, there are more than 700 active acequias in the state, many of them concentrated in Northern New Mexico.

The man-made, gravity-fed earthen canals transport snowmelt and river water to fields for flood irrigation. They each have a governing body called a “mayordomo” or “ditch boss” and elected commissioners who oversee maintenance, water distribution and conflict resolution. 

Some areas have seen traditional acequias absorbed into larger water conservancy districts. The Middle Rio Grande Conservancy District (MRGCD), for instance, covers a 150-mile stretch of the Rio Grande from Cochiti to Bosque del Apache. Here, MRGCD diverts water from the river to the agency’s irrigation system, which delivers it to acequia headgates, where local groups take over.

Most acequias across the state, however, still operate as individual political subdivisions.

Dawn Nieto Gouy grew up in Albuquerque’s historic Los Duranes, a neighborhood where acequias such as the Duranes Lateral run alongside homes and agricultural fields.

“It’s in your blood. It’s in your soul,” Nieto Gouy said, describing the cultural significance of these waterways. She recalled playing with her best friend alongside an acequia near her home as a child. 

“It was like I would spend almost a lifetime in a day getting from our house to the end, meeting at the acequia, running around barefoot and playing and bathing, doing whatever we did there,” she said. “And then the days would just run away from us.”

Despite their long history and cultural importance, acequias—and the people who depend on them—face an urgent threat from climate change. This year, New Mexico’s snowpack hit historic lows in early spring, dropping to around 20 percent of normal as of April 20. That record-low snow collided with warmer-than-usual temperatures—the state experienced its hottest March in recorded history, surpassing the old record by 4.4 degrees Fahrenheit—to produce this outcome.

In Northern New Mexico, water rights holders—known as parciantes—expressed concern that the meager snowpack wouldn’t sustain the many acequias that weave through the region. One Santa Fe New Mexican reportdescribed the dire situation in the village of Truchas, where acequias were already running low at the start of the irrigation season.

Further south, MRGCD announced in late March that there may not be enough water this year to meet the needs of its 11,000 irrigators, including acequia parciantes. And as of March 27, the Rio Grande showed early signs of drying at the San Acacia reach, an area that typically begins to diminish in early summer. 

“Historically, we used to talk about May as being a very early time to see that happen,” said Anne Marken, river operations manager for MRGCD, which oversees irrigation, drainage and river control for around 60,000-70,000 acres of farmland. “Last year it happened in April and we were all very shocked by that, but this year it happened in March.”

Praying for Rain

During times of water scarcity, acequia communities have long relied on sharing practices. Users may be assigned specific days or hours when they can access water, for instance. Similarly, MRGCD utilizes rotating water deliveries within its district—delivering water to different irrigators at different times, depending on availability—and is implementing that management strategy this year. 

“Water users are strongly encouraged to take water when it is available, future opportunities may be uncertain,” the agency said in a press release.

Other than that, water managers and acequia parciantes across the state are praying for rain to help replenish the system and water fields.

“There’s not a ton of tools in our toolbox right now from a water management perspective,” Marken conceded, explaining her department is currently working in a run-of-the-river system, meaning that the only available water is what is in the river.

The biggest potato cull pile the #SanLuisValley has ever seen: An estimated hundred million pounds will need to be disposed of after overproduction and a warm March ruin potatoes in storage — AlamosaCitizen.com #RioGrande

April 14, 2026

The San Luis Valley has an overabundance of potatoes in storage here in mid-April that, because of the warm winter, is leading to concerns about what happens as a new growing season begins.

An historically hot March that punctuated a warm winter overall is creating quality standard problems in the potato bins of the Valley. If a potato bin doesn’t meet the quality standard, it doesn’t ship. [ed. emphasis mine]

“When we start to lose a bin, a bin can be 5,000 sacks, 10,000 sacks, up to 100,000 sacks … then we look at a really gigantic pile of potatoes that has to be managed,” explains Jeff McCullough, who operates Spud Seller farms and potato packaging and distribution in Rio Grande County.

McCullough does the math on the amount of potatoes estimated to be in storage that may not find a market or their way to processing facility and comes up with a mind-boggling figure on how big a problem this is.

Based on conversations with other operators in the Valley, he is estimating a million hundredweight worth of potatoes, or about a hundred million pounds of potatoes that may not be sold or processed this year and would have to be dumped.

Others say the figure may be an underestimate. And they say the problem isn’t just in the San Luis Valley but everywhere potatoes are grown as an oversupply and weak market keep potatoes in storage.

How a warm winter hurts the quality of potatoes in storage: “A potato is a living organism. It generates its own heat. And so throughout the wintertime, we still have to push cold air and cool those potatoes down. Otherwise, those potatoes will generate heat and once they generate enough heat, they’ll sprout, then they won’t meet a quality standard at all … There’s a lot of instances where you lose an entire bin because the bin generates too much heat before you can get it sold.” — Jeff McCullough, Spud Seller 

It’s the responsibility of each grower to figure out how to dispose of what’s left over from their fields, but with such a large amount, McCullough and others see it as a communitywide problem that is going to require input at the public level on what to do.

To that end, McCullough has been meeting with county officials and has a joint meeting set up to address the situation with county commissioners representing Alamosa and Rio Grande counties.

“We’re going to need to find a good way to dispose of these potatoes,” McCullough says.  

Adding to the problem is the loss of the Colorado Gourmet processing plant in Center that burned down two years ago and isn’t coming back, leaving the Valley with only one processing facility. It handled about 40 percent of the potatoes that got processed each year.

Potato production in the Valley remained steady in 2025. Total potato acreage went to 51,474 acres from 50,188 acres in 2024, according to the 2025 USDA acreage report. A tight potato market, though, is keeping potatoes in storage as local growers work with distributors over the next three months to move potatoes and clear storage for the 2026 crop.

“The next harvest will start roughly, the first of September, and so the ideal situation is we are out of this crop the day that we start harvesting the new crop,” says McCullough. 

The Spud Seller needs to move about 550,000 sacks of potatoes – each sack 100 pounds – by around July to keep pace and to keep the backlog of potatoes from growing at his operation, McCullough figures.

Others are in similar boats. 

“There’s still a shit-ton of potatoes out there,” said Mark Lounsbury, general manager of Grower Shipper Potato Company. 

Lounsbury and McCullough’s packaging and shipping operations are two of the biggest in the Valley.

2025 top six certified varieties of SLV spuds were:

• Reveille Russet (2,611 acres)
• Russet Norkotah selections (2,444 acres)
• Canela Russet (457 acres)
• Soraya (429 acres)
• Teton Russet (339 acres)
• Alegria (371 acres)

The variety of potato in storage matters, too. Some varieties have a longer dormancy period and will store longer, while a less dormant variety like a Russet Norkotah that wants to sprout has to be gone by a calendar date, McCullough said.

Newer varieties of potatoes are creating efficiencies on the growing side, using less water and creating more yield even as less acreage is planted.

Potato growers have to follow rules for cull piles outlined in the Colorado Seed Potato Act, which will make the dumping of the amount of potatoes McCullough and others are talking about all the more challenging to figure out.

Hence the outreach to county officials.

The process involves smashing or crushing each individual potato, spreading them out in a very thin layer and then running them over with something. “For example, we have a manure spreader that we run our potatoes through and it chops them up and it kind of disintegrates them. And then it spreads them out into a thin layer, and then once you break the skin of that potato, it dries out really well,” McCullough says.

“We’ve been in situations in years past where we’ve had to dump a lot of potatoes, and it’s because of those years that we’ve come up with these new laws.”

But Valley potato growers rarely see a year where a hundred million pounds of potatoes may have to be dumped. Then again, the Valley has never seen a March where the temperatures reached into the 80s and caused potatoes in storage to want to sprout.

An oversupply of potatoes, coupled with a burned-down processing plant and a much too warm winter, is creating the conditions for a biggest cull pile of potatoes the Valley has ever seen. Proper disposal is essential.

“It is not one person that can swoop in and solve this,” said Tara Artho, executive director of the Colorado Potato Administrative Committee in Monte Vista. “It’s going to take the community.”

Local rivers likely reached peak flow in March: Forecasts show little relief from high temperatures and low precipitation as reservoir operators make plans for release of irrigation water — Heather Dutton (AlamosaCitizen.com) #RioGrande #snowpack #runoff

April 13, 2026

Water Managers anticipate flows in the San Luis Valley’s rivers and creeks will be very low in spring and summer 2026. 

The Colorado Division of Water Resources Division 3 Engineer’s April 6 10-day report forecasted the total annual flow of the Rio Grande at the Del Norte gage will be 270,000 acre-feet, which is 42 percent of the long-term average. For reference, flows of the Rio Grande at Del Norte in 2018 totaled 280,400 acre-feet. The forecasted flow of the Conejos River system is 110,000 acre-feet, which is 37 percent of the long-term average. The snow water equivalent on April 9 for the Upper Rio Grande Basin was 12 percent of the median for 1991-2020. 

The National Weather Service is forecasting hot temperatures along with below average precipitation into the summer. The irrigation season began on March 23 on the Rio Grande and March 16 on the Conejos River. As such, on-stream reservoirs are required to pass all inflows to satisfy the needs of downstream senior water rights holders. Given the low amount of snow, the exceptionally warm spring temperatures, and the anticipated summer drought conditions, it is possible that local rivers reached peak flow in March. 


Rio Grande operations

The operators of reservoirs on the Rio Grande will time their releases of irrigation water to coincide with the canals being in priority to allow water to reach farmers. It is anticipated that many of the canals will only be in priority to divert water for a short time window, in some cases only days or weeks. As such, releases of irrigation water will begin in the next week. 

The Santa Maria Reservoir Company will begin releasing stored irrigation water into North Clear Creek on April 14 at a rate of 200-300 cfs for 10 days. Additional releases will continue as farmers call for water. Rio Grande Reservoir will also begin releasing stored irrigation water into the Rio Grande on April 14 for approximately 20 days. The rate of the release will start at 100-150 cfs and increase up to 350-450 cfs. After deliveries are complete, releases will be limited to the natural inflows. As such, boatable flows on the Rio Grande may diminish as early as mid-May.

Entities including Colorado Parks and Wildlife, the San Luis Valley Water Conservancy District, and the Rio Grande Water Conservation District store water in reservoirs in the Upper Rio Grande Basin and call for releases for their operations in accordance with their water rights decrees. 

Where possible, releases by these organizations will be prioritized during hot periods to supplement the natural flow of the Rio Grande and the South Fork of the Rio Grande to reduce high water temperatures to protect the health of fish. Unfortunately, there may not be sufficient water to keep temperatures below thresholds for responsible fishing. As such, anglers are encouraged to check temperature gages and not engage in catch and release fishing if water temperatures reach exceed 70 degrees. Temperature is measured at the 30 Mile Bridge, Wagon Wheel Gap, Del Norte, and South Fork Gages and can be viewed at the Colorado Division of Water Resources’ website (dwr.state.co.us).

Conejos River operations

Platoro Reservoir is passing inflows, which were 10 times higher than average for much of March because of rapid snowmelt. The Conejos Water Conservancy District allocated 6,500 acre-feet of project water to the irrigators. Unfortunately, river flows are currently too low to carry that water to farmers’ headgates and water will not be released unless river flows improve. It is likely that the river will have dry up points below Highway 285. Anglers are encouraged to check temperature gages below Platoro Reservoir and near Mogote before engaging in catch and release fishing.

Rethinking How the #UnitedStates and #Mexico Share the #ColoradoRiver — Eric Kuhn, Anne Castle, Carlos de la Parra, John Fleck, Jack Schmidt, Kathryn Sorensen, Katherine Tara #COriver #aridification

March 26, 2026

Since 1945, the United States and Mexico have managed common interests on their two largest shared rivers systems, the Colorado and the Rio Bravo/Rio Grande, under the terms of the 1944 international treaty that was designed from the beginning with tools to adapt to changing hydrologic and societal conditions. A recent emergency agreement on the Rio Bravo/Rio Grande illustrates what is possible, and with old river management rules on the Colorado both within the United States and between the United States and Mexico about to expire, we are at a moment of opportunity for meaningful change. The core problem on the Colorado River, which we address in the analysis that follows, arose from decisions made in the first half of the 20th century to allocate fixed volumes of water. As usage patterns and hydrology change in the 21st century, fixed volumes no longer work. [ed. emphasis mine] A shift to a percentage-based split between the United States and Mexico on the Colorado River, based on the river’s actual natural flow, would provide a solid foundation for the two countries’ joint management of the Colorado in the decades to come.

What about this warm, wacky and very weird weather? Meteorologists say #Colorado’s record temperatures in March were “anomalous.” Will we shrug it off, like so much other evidence of #ClimateChange? — Allen Best (BigPivots.com) #snowpack #runoff

Colorado’s top-25 March heat waves since 1951, defined as 4-day averaged statewide temperatures. Colorado’s warmest heat wave (set last week, March 18-21) eclipsed its previous warmest heat wave (March 23-26, 2004) by nearly 5°F. Data from NCEI nclimgrid via the Colorado Climate Center

March 30, 2026

It was weird, it was wacky. This string of summer days in Colorado that arrived around the first day of spring was extraordinary. Will it change us in some fundamental way?

It’s not like 9/11, the day we saw people jumping from the skyscrapers in New York City to escape an even more cruel death by fire. We knew instantly that the world was different and in a very big way.

But doesn’t this anomaly deserve more than a shrug of the shoulders? As summer arrived in the last days of winter, I heard several people say, “Well, enjoy this nice weather” as you passed through their doors. A well-intentioned pleasantry but detached from a vital truth. Nice weather for Arizona maybe, but this was Colorado.

Winter had altogether been very, very warm. November was the third warmest November on record across Colorado. December the warmest. February also broke records.

Then came March. Alamosa, a town at 7,543 feet in elevation in Colorado’s San Luis Valley, notched 11 record highs during March going into the last weekend. This included nine in a row from March 18-26. Of special note was the record high of 83 degrees recorded on March 21. It broke the old record by 7 degrees. It also was a higher temperature than has ever been recorded in Alamosa in April.

Crested Butte had a high temperature of 68, a full 10 degrees higher than the old record for that date.

Dates of first 90°F or warmer day in Fort Collins from 1895-present. The blue dashed line shows the 1991-2020 mean 90°F or warmer day, which is June 9. Data from ACIS.

Fort Collins got to 91 degrees, also 10 degrees more than the old record for that date. It was the highest ever mark for March — but also higher than anything ever recorded in April, whose record remains 89 degrees. The average first day for 90 degrees in Fort Collins is June 15.

Allie Mazurek, of the Colorado Climate Center staff, posted a report on Thursday morning that defines in numbers what she calls an event “impossible to ignore.” Included in her presentation is the  chart atop this essay that shows how anomalous this four-day streak of heat was compared to others in Colorado during March.

This heat was nearly uniform across Colorado. “There were far more stations in the state that broke all-time monthly high records for March than did not,” wrote Mazurek. “To see monthly records shattered by more than 5 degrees F across numerous stations is truly remarkable. The kind of heat that we saw last week across Colorado is more typical of June or even July.”

Remarkable about theheat in Colorado was not only its intensity but its longevity across four days (March 18-21). “Over that period, several locations set new monthly records every one of those days, with each day being warmer than the last.”

March maximum temperature records at various long-term weather stations throughout Colorado. Data from ACIS.

This heat comes at a particularly bad time. The thin snowpack was already melting. The deepest snowpack in Colorado’s mountains has traditionally occurred in early May, because of accumulations at higher elevations.

That assumes a normal of some sort — although it is questionable whether “normal” has any true meaning given how fast the climate is now changing. So take this for what it’s worth: the statewide snowpack this past week sat at 38% of the 1991-2020 median. And what must be noted here — as with the temperature records that were broken — is that we have had an exceptional increase of heat in Colorado in the last 25 years.

Notable in the lifetimes of baby boomers in Colorado were the winters of 1976-77 and 1980-81. This year’s meager runoff will almost certainly surpass those dry years. New is the heat.

High-pressure heat domes can be predicted but are notoriously challenging to forecast weeks or months in advance. They also remain rare, but the warming atmosphere makes them more likely.

“We do have high pressures every year across the West,” said Mark Wankowski, a meteorologist at the Pueblo office of the National Weather Service. “This one was extremely early.”

Writing from Colorado Springs last weekend in an essay in The Atlantic titled “There’s No Way the West Will Have a Normal Summer,” Rebecca Boyle explained that the heat wave was created by a “a bizarrely strong ridge of high pressure in Earth’s atmosphere.” This ridge suppressed cloud formation and brought in warmer air. “Such atmospheric ridges are more common in the summer, but this one would be unusually intense even for that season.

Kaitlyn Trudeau, a senior researcher at the science nonprofit Climate Central, told Boyle this was the strongest ridge ever observed in March. Climate Central has developed a prediction model that assesses how much a warming trend or record high can be attributed to human-caused climate change. According to this model, the western high temps were five times more likely because of elevated greenhouse gas emissions.

I feel rattled by this heat. You may remember the high-pressure cooker that broiled the Pacific Northwest in June 2021. Temperatures spiked to 116 degrees in Portland. People in apartments that were not air conditioned died from the heat. In Multnomah County, the location of Portland, 72 deaths were attributed to heat. Farther north, in British Columbia, the town of Lytton went up in flames after several days of intense heat, including a temperature that reached 121 degrees Fahrenheit.

After that heat, the Colorado Public Utilities Commission asked Xcel to assess how well it could respond to somewhat similar heat in Colorado. The company concluded it had the resources.

But this week, in the wake of the intense spring heat, the PUC commissioners were clearly worried, part of a growing concern about “resource adequacy.” Will Xcel be able to meet critical electrical needs if another heat dome arrives in Colorado this summer? The commissioners asked Xcel to return with strategies for reducing demand from big industrial customers if demand for cooling spikes.

Colorado Drought Monitor map March 24, 2026.

Curious about an on-the-ground perspective from this heat and sparse snow, I called Paul Bonnifield in Yampa. A drought map colors that part of northwest Colorado mahogany, beyond extreme drought and in the realm of “exceptional.” What did exceptional drought look like to him?

Yampa lies at the headwaters of the Yampa River, between the Gore Range and the Flattops. It has a bucolic setting, a place of hay meadows and grazing cattle. Lying upstream are a couple of reservoirs on the edge of the Flattops.

It’s not uncommon for snow to remain on the ground at Yampa, elevation, 7,900 feet, in late March. Not this year. “The ground is hard, just dry, dry, dry,” said Bonnifield.

Bonnifield grew up a few miles away at Phippsburg, a railroad town, and he worked on the railroad himself in addition to spending time teaching and writing at a college in Oklahoma. He’s now in his late 80s and can put this year’s anomalous heat and drought into perspective.

“We are in serious trouble,” he said. “I’ve never seen it like this before.”

Less water will mean less hay production in Egeria Park, where this photo was taken about eight years ago. Photo/Allen Best

Unless a miracle arrives in the form of spring rain and snow, ranchers in Bonnifield’s area — called Egeria Park — will have to decide what to do with their cattle. There’s not enough water to grow grass. There will be wildfire smoke besotting the sky, dampening tourism. And as for river rafting downstream on the Yampa – not likely. Steamboat Spring has already imposed watering restrictions for lawns.

Denver Water this week adopted lawn-watering restrictions for its customers in Denver as well as those in surrounding jurisdictions. It has 1.5 million customers, directly and indirectly, in the metro area.

Nathan Elder, the utility’s manager of water supply, reported to board members on Wednesday that snowpack levels are at historic lows and melting earlier and more rapidly.

Denver Water diverts water from rivers and creeks on both sides of the Continental Divide. In Grand and Summit counties, at the headwaters of the Colorado River, the snowpack was 53% of normal and the lowest on record for the date, Elder said. The South Platte River has it even worse, just 40% of normal.

“These are really unprecedented snowpack conditions,” he said at the meeting on March 25. During the previous week — the week of the heat dome —Denver had lost 25% of its snowpack in the areas it collects water, he reported.

Denver Water is asking the 1.5 million households and businesses that get water from the utility to refrain from starting to irrigate lawns, including this one in southeast Denver, until mid-May. Photo credit: Allen Best/Big Pivots

Can it get worse? Well, yes, it could. “It’s well documented that, in part, due to climate change, the runoff generated from a given snowpack has declined when compared to the past,” said Elder. “So we can expect even less water from this already low snowpack.”

Might a miracle arrive? After the drought and heat of 2002, metro Denver was stressed. Then, on St. Patrick’s Day 2003, three feet of snow fell. In the San Luis Valley, monster rainfall last fall swelled the Rio Grande, leaving water in the soil that will help even now as farmers begin preparing their fields for early plantings.

NOAA projects continued likelihood of above normal temperatures and below-normal precipitation across Colorado, including Denver’s collection area, during April.

Denver aims to reduce water use 20% by its customers in Denver and in outlying suburbs. It will permit lawn watering two days per week and then after 6 p.m. or before 10 a.m. It is also urging customers to refrain from watering their lawns until mid-May. That’s not an easy ask when it feels like June in March. In April, Denver Water’s board members will be asked to approve “drought pricing.”

Russ Schumacher, the state climatologist in Colorado, is called upon frequently to give programs to water organizations and others. This past week he gave a presentation to the Fort Collins Chapter of the Colorado Renewable Energy Society.

“Wildfire certainly is top of mind,” he said while showing a time-lapse video of a wildfire called High Park Fire that occurred west of Fort Collins in 2012.

Dry and hot temperatures leave Russ Schumacher, the state climatologist, apprehensive about potential wildfires this year. Above photo is from the Longmont area in August 2020, a hot and smoky year when wildfires continued almost into November. Photo/Allen Best

Global warming is a simple proposition, he said.

“If you put a pot of water on your stove you’re not going to be able to predict all those individual bubbles or exactly when it’s going to start boiling,” he explained. “But you know that when you turn that heat on, the water’s going to get warmer and it’s going to continue to warm the more heat that you add. So the physics of climate change is actually rather similar in that regard.”

And, of course, adding greenhouse gases to the atmosphere traps heat, which heats the planet. “When you add heat to something, then it warms.”

Colorado has had outliers of heat before. The Dust Bowl during the mid-1930s was a time of heat and drought. More hot and dry arrived in the 1950s.

This chart shows snowpack in Colorado. The heat dome caused rapid melting of snow. In the San Luis Valley, heavy rains of last October may allow farmers to survive better than during 2002.

Dry has not changed. The hot has changed. What used to be an extremely hot year in Colorado is now a fairly average year or just slightly-above-average year, said Schumacher.

Citing NOAA data, Schumacher showed a sharp rise of almost 2.5 degrees Fahrenheit since 1980. The heat has been most acute in the summer and fall — although, obviously, recent months spoil that easy narrative.

With a moderate rate of emissions, we can expect another 2.5 to 3 degrees of warming by around 2050. That expectation comes with a disclaimer about uncertainty. It’s a best guess.

Precipitation has been more complicated than temperature in Colorado. As for the future, it remains a puzzle. Could be more, could be less. Either way, it will be impacted by temperatures.

“If it’s warmer, if it‘s windier, it’s less humid, the air is thirstier for water from the soils, crops, forests, reservoirs, wherever.” Schumacher said. “As it gets warmer, that evaporative demand goes up. The air is thirstier for water, and this has big implications for drought and water supply and water resources.”

Might warming occur more slowly? That’s possible, and a possibility tied strongly to whether global emissions of greenhouse gases can be abated. Given the current political climate in the United States, a key player in world politics, this low-emissions scenario looks highly unlikely. More likely are the heat domes.

Like the pot of water on the stove that Schumacher described, we’re certain to see more heat bubbles. Hard to tell where and when they will be, but there will be more of them. That leaves me distinctly uncomfortable. In Colorado I have felt 104 degrees. I cannot fathom the 118 degrees of Portland.

The first session was titled, “State of the Rio: The 2026 river outlook general basin and compact projections” and the general consensus from the speakers was, as Brad Udall recently said about the Upper Colorado River Basin, “There is no historical analog,” for these conditions. Snow drought is front and center in the San Luis Valley these days.

Precipitation in the basin started out the water year in great shape due to a big rain event in early October. Since then there have been modest accumulations but has flattened out since late February to date.

Division Engineer Craig Cotten started off his presentation with the basin-filled snowpack map for Colorado. He joked that, “The good news is, the Rio Grande is not the worst in the state.” It is not a good year as far as #snowpack and many SNOTEL locations are already melted-out.

Projected streamflow is not looking good and the forecast will likely be worse when the April 1, 2026 numbers are released by the NRCS. However, streamflow right now is looking okay, there is a lot of water in the #RioGrande at this time for example. That means that the little snowpack in the basin is already coming off.

Colorado’s Rio Grande Compact compliance numbers heading into the scary diversion season are a positive. There is no debt owed to New Mexico and Texas. With the early onset to runoff season the State Engineer allowed irrigation to start on March 23, 2026. Current estimated streamflow for the Rio Grande at Del Norte (the compact USGS gage used for the river) is 305,000 acre-feet which carries a compact obligation of 76,000 acre-feet to New Mexico and Texas. For the Conejos River the estimated upper index annual flow is 165,000 acre-feet and the downstream obligation is 27,500 acre-feet. However, water levels are going to drop in the unconfined aquifer significantly this year due to low flows in the river. The situation in the aquifer is bad and it is going to get worse.

Cotten updated the attendees about the Rio Grande Compact lawsuit status. It is mostly a fight between Texas and New Mexico and the latest stipulated agreement has been approved by the Special Master. The U.S. Supreme Court is expected to approve the agreement.

Nathan Coombs, in keepting with the symposium theme said, “I believe we’re going to be alright this season we’re going to survive. People in the San Luis Valley are working together and we’re going to get through it.”

Heather Dutton gave an overview of reservoir operations for 2026. It is possible that all irrigation water will be released in April and May. She added, “If you’re going to fish the streams emphasize fishing in the morning and visit one of our valley breweries in the afternoon. It’s going to be tough year for all of us. Please keep the farmers in mind.”

Reclamation informed attendees about the current status of the Closed Basin Project. Project priorities are:

  • Colorado’s compact deliveries
  • Mitigation for construction and pumping
  • Eliminate Colorado’s Rio Grande Compact deficit
  • Other beneficial uses/irrigation
Slide from Amber Pacheco

The session “Twenty years of subdistricts” illustrated how the well owners have been working together over the years to determine a solution to the declining unconfined aquifer. Because groundwater is not separate from surface water the lowered levels in the aquifer affect surface streamflow in the Rio Grande. Valley pumpers have formed several sub-districts fashioned around the different hydrology in areas of the aquifer and are retiring some wells and taking land out of production. Another strategy used has been o develop augmentation plans to offset pumping. All of the strategies involve fees to sub-district members. There is extensive coverage of the issue on Coyote Gulch if you are interested in taking a trip down memory lane.

The session “Flowing together: Agriculture, rivers, and communities in partnership” was an overview of collaboration between the City of Alamosa, the West Side Ditch, and Rio Grande Headwaters Restoration Project on the river at the east side of Alamosa. It included a new headgate for the ditch company and will include a new levy orientation and access to the river from Cole Park. The speakers emphasized that it would not have happened without collaboration and the emphasis on creating a win for all stakeholders. For example, Bill Schoen credited the Rio Grande Headwaters Restoration Project for finding funding for the new headgate which is often a problem for mutual ditch companies. Daniel Boyes of the Restoration Project said that the new headgate helps fish and safety for boaters.

The final session before the keynote was “Perspectives on valley recreation” where access to public lands and the value of building a recreation economy to bolster valley opportunities were discussed. While 39% of Colorado’s agricultural output is from the valley economic activity is seasonal. The discussion centered around bringing tourism to the valley to improve the outlook for employment and economic growth.

The keynote speaker was Ben Golfarb and it was a real treat. I never tire of learning about “Nature’s Engineers” and the amazing effect this keystone species has on hydrology and habitat. Trapped extensively by fur traders to enable the fashion industry in the 19th century the species was nearly extirpated from the North American West. Along with a torrent of information and photographs, Goldfarb informed attendees that the native tribes did not participate in trapping because of their understanding of beaver’s role in the arid lands.

March 13, 2026

An early start to the irrigation season in the San Luis Valley is coinciding with the arrival of spring’s first heat wave.

Craig Cotten, Division 3 engineer for Colorado Division of Water Resources, announced a staged approach to opening the water year for producers in the Upper Rio Grande Basin. 

The water season will begin on March 16 for surface and groundwater irrigators in the Conejos River area (Water District 22), the Culebra Creek area (Water District 24), the Trinchera Creek area (Water District 35) and the La Jara Creek area. The irrigation season will begin on March 23 for all surface and groundwater irrigation structures in the Rio Grande area (Water District 20).

“I decided to start the irrigation season earlier than the presumptive April 1 date for many valley areas due to the very warm, dry spring and the low current snowpack. We are already seeing an increase in streamflows due to the warmer weather, and it is beneficial for water rights holders to be able to use this water while it is available,” Cotten said in an email exchange with Alamosa Citizen.  [ed. emphasis mine]

On the Conejos River and Rio Grande, another reason is that Colorado is projected to meet its compact obligation without needing to deliver water during the irrigation season, Cotten said. 

“In order to avoid a significant over-delivery of water to the stateline, I have decided to begin the irrigation season on these rivers prior to April 1.”

The coming week of March 16 could see record-setting temperatures to the official start of spring. The forecast calls for midweek daytime highs in the low- to mid-70s. March has seen 21 of its 31 days establish new record high temperatures since 2004, a heating trend that accentuates the warming winters and spring months.

This March opened with back-to-back days of new daily high records. More heat records could fall in the coming week. The irrigation season can’t open soon enough.

Coyote Gulch’s excellent EV adventure: 2026 #MonteVista Crane Festival

Sandhill Cranes just before sunrise March 8, 2026, Sange de Cristo Mountains in the distance.

We woke up to clear skies and very cold temperatures (6°F) for Sandhill crane viewing on March 8, 2026. The Sandhills spend the night on the ground, usually in shallow water as they do not perch, and then start stirring and looking for a good breakfast spot like the field in the foreground in the photo above.

Video of Sandhill cranes in the early morning on March 8, 2026, San Juan mountains in the background. Sound up!

Charging during the festival was easy as pie at the Colorado Welcome Center in Alamosa. For the trip home I charged in Salida (excellent food at Mojo’s Eatery) and Bailey. Charging to and from the San Luis Valley from Denver is convenient and reliable. There is no reason any longer in Colorado to drive a vehicle with a tailpipe and pollute the atmosphere.

Here’s a writeup from The Alamosa Citizen:

Monte Vista saw big crowds for the 43rd annual Crane Festival. The Outcalt Event and Conference at Ski Hi Complex was teeming with people participating in the crane tours and nature work sessions. The retail vendors reported healthy sales. The sandhill cranes themselves didn’t disappoint. The majestic long-legged creatures were in the tens of thousands in the fields around the Monte Vista Wildlife Refuge. The cranes will stick around a bit longer.

February 28, 2026

Rancher Greg Higel usually opens a barn door for his cows to enter during the cold winter nights. Lately he’s been leaving the cows out at night because “the less you mess with them, the better off they are.”

The February weather has been warm enough not to mess with the cows.

The last two Februarys – 2025 and 2026 – have seen the daily maximum temperature average 50 degrees-plus in Alamosa, according to National Weather Service data. That has never happened before in the Valley’s climate history. 

National Weather Service records as far back as 1948 show only the past two Februarys so warm that ranchers like Higel, who are in the midst of their calving season, worry less about their cows at night and more about their grassfields and what the warm winter means for the ground itself. Included in that are overnight temps averaging in the double digits and frequently in the 20s.

“I don’t think it’s good for the farm ground,” Higel says. He was hopeful the heavy October rains that had flooded his meadows would leave water frozen in the fields through the winter months. But the water hardly froze and the worry now is the anticipated light spring runoff and available water for the grass growing season ahead.

Of the 28 days in February this year, 20 have seen the daily maximum temperature exceed 50 degrees. The highest temperature for the month was 65 degrees on Feb. 25, following 64 degrees on Feb. 24, which established a new high for the date.

February 2025 was just as warm and warmer, with an average daily high temperature of 52.8 degrees. It was a year ago when the phenomenon of average 50-degree weather days was first noted after the mercury hit 60 degrees on 5 of the first 7 days of last February.

Suffice it to say, if it is this warm in February in the high mountain desert, the snowpack is going to suffer. The Upper Rio Grande Basin enters March measuring 55 percent of median on a snowwater equivalent index, which is what worries irrigators. 

And it’s not just ranchers and farmers who should be paying attention.

Adam Moore, supervisory forester with Colorado State Forest Service, says trees around the home need watering when the winter months are this warm. The constant threat of wildfire is another reason to pay attention.

“The SLV and the plains are still facing red flag warnings. There have been large grass fires in Oklahoma and Kansas. The conditions for those fires are not much different than what we have in the SLV. Just like the red flag warnings all year long, wildfire preparedness should occur all year,” he says.

Just don’t get too far ahead. Gardeners should stick to the normal planting times, with mid-April being the earliest for any tree planting.

“Don’t let the warm weather fool you and plant early,” Moore says. “We still stand the chance of late frosts.”

Tell that to Tomas Miera.

“I’ve been riding all winter. My goodness, today is going to be like 64,” he says, standing in his front yard in a short sleeve shirt, shorts and shining his Harley Davidson. “I’m going for a ride later on.”

February allows for it. It’s never been this way.

Massive #solar project proposed where crops once grew — AlamosaCitizen.com #SanLuisValley #RioGrande

Spud Valley Energy Center’ would be built on 2,578 acres near Mosca and Hooper; it would ultimately develop 600 megawatts of solar energy and 600 megawatts of battery storage.

February 22, 2026

‘Spud Valley Energy Center’ would be the largest ever conceived for the Valley, and one of Colorado’s biggest solar projects, at a time when ag producers are being forced to reduce their footprint to save on the water

It is an agricultural corridor in Alamosa County that is drying faster and seeing more buy-and-dry deals than other parts of the San Luis Valley due to the scarcity of water from the Upper Rio Grande Basin.

On 2,578 acres of private land off State Highway 17 leading into Mosca and Hooper, a number of families are entering into contracts with NextEra Energy and its bid to ultimately develop 600 megawatts of solar energy and 600 megawatts of battery storage on the fields that once grew crops.

The solar project, dubbed the “Spud Valley Energy Center,” is the largest ever conceived for the Valley and one of Colorado’s biggest. It comes at a time when ag producers in Subdistrict 1 of the Rio Grande Water Conservation District are being forced to reduce their footprint to save on the water. Solar development then, in a Valley plentiful with sunshine, becomes an alternative for the land and a company like NextEra Energy has the means to make it happen.

“A number of the landowners we’re working with have already either retired their wells or they’re participating in CREP (Conservation Reserve Enhancement Program) to rest their lands for longterm,” said Evan Reimondo, the project manager, in an interview with Alamosa Citizen.

Spud Valley is perfectly sited when you consider the other solar development already in the corridor, the Public Service Co. substation near the project site, the water conservation subdistrict it is in, and Alamosa County’s own interests for solar development through its 1041 permit process.

A different solar development proposal — Korsail Energy’s Cornflower Solar project — had its permit application denied by the county commissioners last year after it met a headwind of resistance from locals concerned about the location of the project that was within a migratory range of sensitive wildlife areas in west Alamosa County. 

Korsail was seeking to build 90 megawatts of solar and 80 megawatts of battery storage on 986 acres, but was doomed because of the location it selected. NextEra Energy’s Spud Valley doesn’t seem to carry that burden with its location, and at 600 megawatts puts the Valley on the map for solar generation to support Colorado’s goal of a state power grid built on 80 percent renewable energy by 2030.

“Colorado’s demand for electricity is going to keep growing as the population grows and technology develops and all of those things,” said Reimondo, Spud Valley’s project manager. “So we’re preparing for the future when we over-permit. By permitting for 600, it gives us that future flexibility.”

The plan is to build an initial 200 megawatts of solar and 200 megawatts of battery storage, and then stage to 600 megawatts of each from there. The transmission bottleneck — bringing power in and out of San Luis Valley — presents the biggest challenge.

“As the grid is built out, as network upgrades are completed in the future, new (transmission) lines are built, and we’ll be ready to take advantage of that,” Reimondo says.

Alamosa County is currently reviewing NextEra Energy’s 1041 permit application and eventually will hold public hearings at the county planning level and then before the county commissioners.

Reimondo says the company hopes to begin construction in 2027, with the first 200 megawatts of solar and battery storage built and tied into the neighboring Public Service Co. substation by the end of 2029.

Rio Grande Headwaters Restoration Project work near Del Norte results in 7.2-mile stretch of the river being dried up; biologists say it could take three to five years to recover the fishery

Colorado Parks and Wildlife has confirmed a “large-scale fish kill” along the Rio Grande below Del Norte that was the result of a 7.2-mile stretch of the river being dried up as part of a river restoration project.

The Rio Grande Headwaters Restoration Project has its Farmers Union Canal Diversion and Headgate Improvement project underway in the area. During construction on this project a decision was made that caused the ecological disaster.

On Monday, a team of nine CPW staff walked stretches of the river channel and collected as many fish as they could, said John Livingston, southwest region public information officer for CPW.

“There were too many dead fish for the team to collect them all,” Livingston said in an email exchange with Alamosa Citizen.

The state agency was notified by a landowner on Feb. 3 that the north branch of the Rio Grande east of Del Norte was being dewatered, and fish were dying or dead.

Through its investigation, CPW determined that the species impacted include sportfish such as brown trout and rainbow trout, brook stickleback, longnose dace, fathead minnow and white sucker. Additional species such as northern leopard frogs and aquatic invertebrates such as mayflies, caddisflies and stoneflies, among others have also been found dead, according to Livingston.

“A significant number of the fish populations in that stretch died across all age classes. Brown and rainbow trout as small as two inches and up to 24 inches have been found, along with all sizes in between,” he said. 

Brown trout spawn in the fall and this year’s eggs that were laid in the rocky bottoms of the river most likely have been lost, CPW reported.

“CPW faces challenging conditions to determine how many fish perished from the rapid dewatering. Many dead fish have also been scavenged by birds, raccoons, skunks, and foxes flocking to the area and others have been isolated in frozen pools,” Livingston said.

The Farmers Union Canal diversion project received nearly $1.3 million in funding through the U.S. Bureau of Reclamation. The Rio Grande Restoration Project and San Luis Valley Irrigation District are teaming up on the project.

Farmers familiar with the project told Alamosa Citizen a “hasty decision” was made to move ahead on the project during a cold spell this winter, resulting in the drying of the river through private corridors of the Rio Grande.

“There’s a lot happening behind the scenes to remedy this. Landowners are pissed,” one rancher told the Citizen.

CPW is concerned about the fish kill and potential impacts to other species, such as amphibians and aquatic invertebrates, and the potential impacts to the riparian corridor. An aboriginal population of Rio Grande chub, a Tier 1 Species of Greatest Conservation Need, has been documented in this reach of the Rio Grande, according to state parks and wildlife.

“This stretch of river is habitat for the federally endangered southwestern willow flycatcher and the federally threatened western yellow-billed cuckoo. While flycatchers and cuckoos do not overwinter in this reach, they rely on this habitat for nesting and rearing their young every spring and summer,” said Livingston.

Aquatic biologists estimate it could take three to five years to recover the fishery, he said.

“CPW wants to thank the landowners along the river for their cooperation and for providing access to the river for this investigation, and CPW shares their concerns regarding this incident,” Livingston said.

Alamosa Citizen is seeking comment on this from Daniel Boyes, executive director of the Rio Grande Restoration Project.

Special master OKs #RioGrande Compact decree: Resolution of longstanding #Texas-#NewMexico water dispute will go to U.S. Supreme Court for final approval — AlamosaCitizen.com

Click the link to read the article on the Alamosa Citizen website:

February 9. 2026


A 2013 complaint that Texas was being deprived by New Mexico of its equitable apportionment of Rio Grande Compact water has finally been resolved and the compact decree approved by the special master in the case.

In a Fourth Interim Report dated Feb. 6, Hon. D. Brooks Smith agreed with the negotiated settlement by the states and the federal government that specifies how much compact water released by Colorado ends up with New Mexico and how much with Texas. 

The proposed compact decree, which has to be accepted by the U.S. Supreme Court, employs use of the “Effective El Paso Index (‘Index’),” which provides a means of tracking the movement of water below Elephant Butte Reservoir for Texas’ accounting.

“Much like the river whose water the parties have quarreled over for decades, this original action has proceeded in a meandering fashion. First articulated by Texas in its 2013 Complaint, the dispute, in some sense, began about 8,000 years ago, in ancient Mesopotamia, when the Sumerians invented the concept of irrigation and incited a run on Earth’s navigable waterways,” Smith wrote in his report to the U.S. Supreme Court.

For its part, New Mexico countered that it was “excess water consumption in Texas” that interfered with the compact reporting. The standoff between the two states, with Colorado as a third party, lasted until July 3, 2023, when then-Special Master Michael J. Melloy issued a Third Interim Report (“TIR”) on the matter, which began: “Texas, New Mexico, and Colorado . . . have filed a joint motion to enter a consent decree compromising and settling ‘all claims among them arising from the 1938 Rio Grande Compact.’”

The proposed 2023 compact decree was filed with the U.S. Supreme Court, which rejected it at the request of the federal government, and appointed a new special master in Smith. He brought the states and federal government back together for another round of talks, and in June of 2025 visited the lower Rio Grande to talk to farmers and to familiarize himself with the features of the basin.

“I am grateful to the parties, the amici, and all of counsel for their cooperative efforts in organizing and carrying out what was a highly informative and comprehensive real-time view of both the waters of the Lower Rio Grande and the Project,” Smith wrote in his report.

The Effective El Paso Index (“Index”), which is a feature of the proposed compact decree, measures compliance based on the amount of water that actually passes through the El Paso Gage.

“I am pleased that the Special Master has recommended the U.S. Supreme Court accept the parties’ proposed settlement of the Rio Grande Compact litigation. The settlement is the result of collaboration between Texas, New Mexico, Colorado, and the United States; it includes entry of a proposed Compact Decree and dismissal of the United States’ claims,” said Colorado Attorney General Phil Weiser.  “I appreciate the Special Master’s thoughtful engagement in the matter and his recommendation supporting this collaborative result. His recommendation gets even closer to the finish line.”

The last step will be a decision from the Supreme Court, which Weiser said he hopes to receive by June.

February 6, 2026

A “poor” spring runoff.

Reservoir storage that is “not well.”

An unconfined aquifer that is getting “worse and worse,” not better.

Such is the reality of the situation for the Upper Rio Grande Basin and warnings given to the San Luis Valley farming and ranching community on the final day of the 2026 Southern Rocky Mountain Ag Conference.

If you’re a praying sort, it isn’t too early in 2026 to fold your hands together toward the heavens. If not, a good wish or two would be fine as well.

The outlook is that dire. Except for the hope that a changing weather pattern from La Niña to El Niño at some point this year will deliver the goods and avoid even more of a collapse.

“We do anticipate at this moment, at this date that it’s going to be a poor runoff in 2026,” said Pat McDermott of the Colorado Division of Water Resources. It is customary for him and state division engineer Craig Cotten to provide a look back at the recent water year and a look ahead to the next spring runoff.

McDermott typically attempts a positive spin for the large audience that fills the main conference room at the Outcalt Center of the Ski Hi Complex in anticipation of the state water resources report. He did his best by pointing to a rosier outlook in the 2026 Farmer’s Almanac, the last annual edition.

It is the state, after all, that governs groundwater pumping in the San Luis Valley and has metrics Valley farmers are required to meet to stay in business. One is the recovery of the unconfined aquifer through buy-and-dry and reduced groundwater pumping strategies.

“It just kind of gets worse and worse every year that we look at it,” said Cotten in referencing the storage levels of the Upper Rio Grande’s unconfined aquifer and the greater level of recovery efforts crop producers in Subdistrict 1 are facing as a result.

“Unfortunately it’s going in the wrong direction and it has been for quite some time here,” Cotten said in referencing the latest five-year average for storage.


THE NUMBERS

Rio Grande 2025

493,000 acre-feet – Annual index flow or 80 percent of long-term average past 30 years

125,000 acre-feet – Obligation to New Mexico and Texas under Rio Grande Compact 

Rio Grande saw an increase of 95,000 acre-feet due to October 2025 rain.

Conejos River 2025

205,000 acre-feet – Annual index flow or 68 percent of the long-term average of 300,000 acre-feet

46,900 acre-feet – Obligation to New Mexico and Texas 

Conejos River saw an increase of 15,000 acre-feet due to October 2025 rain.

February’s current conditions 

Statewide snowpack: 55 percent of median

Upper Rio Grande snowpack: 48 percent of median

Warmest December on record for nine western states based on 131 years of temperature data.


Nathan Coombs and Heather Dutton, both key players in the water conservation world locally and at the state level, gave further explanation on the changing weather patterns that are impacting the basin and the amount of water available for irrigation.

Coombs pointed to the problem of overnight temperatures in the late fall and winter months, and the fact the Valley just isn’t getting the sub-zero temperatures it used to. 

Look at December 2025, which saw an average daily low for the month of 11 degrees – double digits overnight – when the normal low for December is 0.8 degrees. January of this year had an average daily low of 4 degrees instead of the -1 that is a normal overnight low temperature for the month. It would have been higher than 4 degrees were it not for sub-zero overnight lows in 5 of the last 7 nights of January.

“We’re not sunburning that much harder, we’re just losing the cold,” Coombs said to his fellow farmers.

The timing of when the moisture comes is off, too. Look at the past two water years – 2024 and 2025 – when heavy rains in October came through and added to the total overall amount of water in the Rio Grande and Conejos River systems. 

Too late to help irrigators, but good enough to help the amount of water in the Rio Grande and Conejos River, overall.

“Look at how it’s changing,” Coombs said. “Useful water for irrigation is changing in more ways than just volumes. We’re seeing timing change. So that’s part of what this is. Mother Nature is playing a big role in this. We’ve got to figure that component out a little better. We don’t need to look across the fence at what our neighbors are or aren’t doing. Let’s figure out how we correct to that.”

#Drought, #ClimateChange affect quality of well water: Study shows 15-25% of private #groundwater wells used for drinking water in the #SanLuisValley contain elevated levels of arsenic, uranium and other heavy metals — AlamosaCitizen.com

February 3, 2026

There is another emerging issue that decades of drought and the warming climate is causing in the San Luis Valley – elevated levels of heavy metals in drinking wells that can cause health issues for households that rely on them.

It’s a topic Kathy James, Ph.D., and associate professor with the Colorado School of Public Health, knows well after spending the past three years working with families in the Valley that rely on private drinking wells.

James provided an update to the work during Tuesday’s opening day of the 2026 Southern Rocky Mountain Ag Conference. She reported that 15 to 25 percent of the private groundwater wells used for drinking water in the San Luis Valley contain elevated levels of arsenic, uranium and other heavy metals.

Her confidence in the findings is bolstered by the fact that 850 households in the different counties of the Valley participated in the study and provided samples to help James and her team evaluate the effect drought is having on water quantity and water quality.

“The comprehensive information that we have about distribution of metals across the Valley is by far one of the best we’ve seen in most western states that do experience elevated metals,” James said.

She noted how low snowpack impacts the age of water underground and ultimately the quality of water people are drinking from a private well.

The Upper Rio Grande Basin, like the Colorado River, is suffering from snow droughtsin the high elevations of the west and below-normal spring runoff levels.

Less snow, less spring runoff for recharge of the aquifers, and higher levels of arsenic, uranium and other heavy metals is the emerging issue. James talks more about the study and the team’s findings in the next episode of The Valley Pod, which streams Wednesday on AlamosaCitizen.com

A male house finch belts out his springtime song. Mustard greens have pushed through the loam in my backyard. The hyssop and salvia are greening up, and so are the Mexican sage and globemallow. Sunflowers and poppies are sprouting, and I slept Sunday night with the window cracked open — 38 degrees is usually my threshold for allowing cold air into the room. In the morning, there’s not even a skiff of ice on the birdbath water.

Like many of you, I’ve been walking a fine line between joy and terror this winter.

Oh, it’s so nice to be outside! And I love listening for screech owls and coyotes at night. But these balmy days and nights fill me with dread. They aren’t just omens of a hot, dry year. They also weaken ecosystems and species that rely upon winter. Including humans.

In 2025, Albuquerque experienced its hottest year on record, and at the end of December, more than 80% of the state was in drought.

In early January, Red Flag warnings already exist for Quay, Curry and Roosevelt counties. The National Interagency Fire Center is forecasting above normal wildlife potential for eastern New Mexico in February. And  the soil moisture map looks like the state is breaking out into measles.

Snowpack across New Mexico is grim. (Do you really want to see the median numbers as of early January? Rio Grande Headwaters in Colorado: 52 percent. Upper Rio Grande in New Mexico: 30. San Juan River Basin: 51. Rio Chama River Basin: 57. Jemez River Basin: 17. Pecos River Basin: 34.) And we’re facing continued La Niña conditions, at least through the next three months. 

Meanwhile, New Mexico doesn’t have much in its water savings account; just look at the reservoir numbers from the top of the Rio Chama to the Lower Rio Grande in New Mexico. Heron Reservoir is 7% full; El Vado, 13%; Abiquiu, 58%; Elephant Butte, 8%; and Caballo, 7%.

From this vantage point in early January — with a few decades of warming temperatures, drying rivers, burning forests and aridifying croplands already behind us — it’s clear that human-caused climate change is tightening the noose on a viable future for New Mexicans, and for the wildlife and ecosystems we are bound to, inextricably.

In 2018, the Intergovernmental Panel on Climate Change released a special report, noting that if the Earth’s temperature increased by more than 1.5 degrees Celsius, the climate consequences will be “long-lasting” and “irreversible.” Scientists wrote that human-caused emissions of carbon dioxide would need to “fall by about 45 percent from 2010 levels by 2030, reaching ‘net zero’ by 2050.” 

In 2025, the Earth passed the 1.5-degree Celsius threshold. And we’re nowhere near to cutting greenhouse gas emissions by significant levels. 

Nothing that’s happening right now should be a surprise — not the melting ice caps nor the drying rivers. We’ve had decades to pivot or at least prepare.

Yet, 60 years after President Lyndon Johnson’s science advisory committee warned that the carbon dioxide humans were sending into the atmosphere would cause changes that could be “deleterious from the point of view of human beings,” in 2025, U.S. Environmental Protection Agency Administrator Lee Zeldin launched the Powering the Great American Comeback Initiative, deregulating industries and “driving a dagger straight into the heart of climate change religion.” 

Meanwhile, U.S. Department of Energy Secretary Chris Wright last year told The Guardian that he’s not a climate skeptic. Rather, he’s a “climate realist.” 

“The Trump administration will treat climate change for what it is, a global physical phenomenon that is a side-effect of building the modern world,” Wright said. “Everything in life involves trade-off.”

The men spearheading the Trump administration’s plans know climate change threatens the lives of billions of people and ecosystems ranging from the sea’s coral reefs to Earth’s mountaintops. And their tradeoffs involve the calculated obliteration of longstanding federal environmental laws, the privatization of public lands and watersheds, and of course, the subversion of climate science. (Not to mention, the waging of illegal wars.) [ed. emphasis mine]

In just a few weeks, New Mexico state legislators will convene for a 30-day session. It’s a fast-paced budget session, which means climate and water won’t top the list of priorities, again. No matter what the mustard greens, house finches, bare mountaintops, and drastically low reservoirs show us. 

This winter, temperatures will drop here and there. Some snow will fall. There will be days that feel like winter. But we’re past the point of comforting ourselves that these warm winter temperatures are an anomaly. They are our future. 

Decades ago, I rented an attic bedroom in a house in western Colorado from a woman who was kind and angry and trying very hard and battling demons. Because she had taped handwritten quotes inside the kitchen cabinet next to the sink, every time I reached inside, I would read them. There’s one quote from the late Joanna Macy I think of every day.  

“The point is not to save people. The point is to create the conditions for the possibility of grace.” 

The point right now isn’t to save the planet — or even ourselves or the more-than-human species we rely upon or love. The point is to create the conditions for the possibility of grace. The possibility of a climate-changed future in which all the best and most beautiful things about this Earth haven’t been traded away. [ed. emphasis mine]

‘Sustainability’ is a foundational tenet of modern natural resource management. The concept of sustainable development gained global recognition in 1987 when the United Nations’ Brundtland Commission published its report on Our Common Future, in which sustainable development was defined as “meeting the needs of the present without compromising the ability of future generations to meet their own needs.” In simple terms, this means avoiding the depletion of natural resources and loss of species over time.

Brian Richter

Our research group has just published our third detailed assessment of water resources management in three major river basins in the western United States. Our three studies — focusing on the Colorado River, the Great Salt Lake basin, and the Rio Grande-Bravo — clearly document that water managers and political leaders are failing in their efforts to manage these water resources for long-term sustainability, meaning that they have not balanced water consumption with natural replenishment from snowmelt runoff, rainfall, and aquifer recharge. As a result, reservoir and groundwater levels are falling, rivers are shriveling, and numerous endangered species are in great jeopardy. The livelihoods and well-being of tens of millions of people dependent on these water systems, along with the extraordinary ecological systems and species sustained by these waters, are now at great risk.

As a Native American friend said recently, “our world is out of balance.”

These systemic failures share a common history with hundreds of other stressed river basins and aquifers around the planet. For thousands of years, the human populations dependent on each water source were small enough that water consumed for human endeavors had little to no impact on water sources and associated ecosystems, i.e., their use of water was ‘renewable’ and ‘sustainable.’ But over the course of the 20th century, the growth of human populations and associated food needs grew rapidly — largely without constraint or control — to the point of consuming all of the renewable annual water supplies in many river basins, including the three we studied. Then as we entered into the 21st century, climate warming began reducing the replenishment of rivers, lakes, and aquifers. The balance between water consumption and replenishment became overweighted on the consumption side as the replenishment side got lighter. Our world went out of balance.

The Risks of Continued Imbalance Are Very Frightening

The potential consequences of this imbalance are nothing short of horrific and dangerous in the three basins we studied. Here are some of the highlights from our trilogy of recent papers:

Colorado River “Beginnings”. Photo: Brent Gardner-Smith/Aspen Journalism
  • Colorado River Basin: Since 2000, more water has been consumed than replenished in this basin in three out of every four years, on average. These recurring deficits in the basin’s annual water budget has been offset by depleting water stored in the basin’s reservoirs and aquifers, analogous to pulling money out of a savings account to make up for overdrafts in a checking account. As a result, the basin’s two biggest reservoirs — Lake Powell and Lake Mead — are now 70% empty. There is great concern that if the water level in Lake Powell drops below 3490′ elevation (see graph below), it could become physically impossible to release sufficient water through the Grand Canyon to meet the water needs of ~30 million people downstream. In a worst case scenario, the volume of water flowing out of Glen Canyon Dam could intermittently shrink to a trickle if the dam’s managers determine that continuous use of the lowest river outlets is too structurally risky and releases into the Grand Canyon must be drastically reduced. This calamity would further imperil unique freshwater ecosystems and wipe out the $50 million/year whitewater rafting industry in the Grand Canyon. We estimate that average annual water consumption needs to be reduced immediately by at least 13% below the recent 20-year average to rebalance water consumption with natural replenishment in this basin.

  • Great Salt Lake Basin: The lake has lost nearly half of its volume since 2000, dramatically shrinking the area of the lake’s surface and exposing extensive salt flats around the lake’s perimeter. Those salty soils are loaded with toxic heavy metals including arsenic, lead, and mercury. Recurring high winds blow that dangerous dust into the nostrils and lungs of more than two million people living in the Salt Lake City area. Brine shrimp living in the lake also suffer at low lake levels due to extreme salinity, greatly reducing the food supply for more than 10 million migratory birds along the Pacific Flyway and decimating production of brine shrimp eggs that are a critical feed source for the world’s aquaculture industry. The reduced evaporation from a shrinking lake also impacts the formation of storm clouds that drop the “world’s greatest snow” onto the Wasatch Mountains, site of the upcoming 2034 Winter Olympics. Water consumption in the basin needs to be rapidly reduced by 21% to stabilize the lake.

  • Rio Grande-Bravo: Reservoir storage in this large international basin is now three-quarters empty. New Mexico’s reservoirs hold only 13% of their capacity, presenting a “Day Zero” scenario in which the remaining reservoir storage could be wiped out in just one or two more bad water years. This has created heated political conflict: New Mexico has been failing to deliver the volume of water it owes to Texas under the Rio Grande Compact, and Mexico has been unable to deliver sufficient water to the US under the terms of an international water treaty. Also of great concern is plundering of the vast groundwater reserves in the basin that has accelerated as surface water supplies have run short (see map of groundwater depletion below). Only half of the water being consumed for human endeavors in this basin is sustained by natural replenishment; the other half depends on unsustainably depleting reservoirs and groundwater aquifers and drying the river.

Governance Failures

The response to these crises has been woefully inadequate. Instead of addressing these imbalances at the scale and speed necessary to avert catastrophe, political leaders and water managers have been unable or unwilling to mobilize sufficient corrective actions to rebalance these water budgets. From my observations, there are multiple interacting causes of these governance failures:

  • There is continuing belief among many political leaders and water users that more bountiful replenishment years in the future will restore the massive accumulated deficits in reservoir and aquifer volumes. This belief runs contrary to the evidence of 25+ years of declining water trends and many scientific assessments warning that replenishment will continue to decline due to climate warming and aridification.
  • Water users have not been adequately or truthfully educated about the potential consequences of continued depletion of reservoirs and aquifers, and the rapid rate at which risks are increasing. The lack of honest communication and misunderstanding of pending dangers perpetuates complacency and inaction. What is needed is full and honest disclosure about the degree to which water consumption is out of balance with replenishment, and which water users and economic sectors are at great risk from deepening water shortages in future years.
  • Fearing hostile reaction to any mandated cutbacks in water consumption, political leaders lack the will to force or incentivize the actions required to rebalance consumption with (diminishing) replenishment. There are no plans in the three basins described above for correcting imbalances at the necessary scale and speed. Legislative appropriations to address these crises have been orders of magnitude smaller than what is needed. These meager appropriations serve to placate the general public by giving the impression that responsible actions are being taken, serving as a smoke screen hiding the monstrous dangers on the horizon.
  • Instead of facing the reality that consumption needs to be speedily reduced, water managers continue to flout pipe dreams for augmenting water supplies such as long distance water importation schemes (bring water from the Great Lakes! bring water from the Yukon!), or desalinating ocean water, or recycling water ‘produced’ from oil and gas fracking operations. There is no truthful reporting of how much additional water can be secured by these schemes, how much that water will cost, and who will be able to afford it. Irrigated agriculture is by far the dominant water consumer in the three basins we studied, but there is no way that farmers are going to be able to afford these water augmentation dreams.

The Way Forward: Sustainability Principles

Throughout my career I’ve always said that one should not deliver criticism without also offering solutions. In my Chasing Water book I outlined seven principles for sustainable water management.

Seven Principles

Credit: Sustainable Waters

I continue to believe in this recipe for water sustainability. But I need to offer some important clarifications:

  • Principle #1 is arguably the most important. Given that water consumed on farms is typically much greater than is consumed in cities, it is critically important to meaningfully engage farmers in water planning because they will bear the greatest burden of any limitations placed on water consumption. They can bring their best ideas forward, and in doing so help to ensure that water plans address both their concerns and their abilities to adapt. But it is essential that any water plans be built upon an honest and technically credible assessment of how much water will be available in the future.
  • Principles #2 and #3 should not be permanent, static volumes. Under a changing climate, the imposed limits need to be adaptive to changing water availability; during wet periods more water can be consumed, but lesser volumes should be allocated during dry times. I believe that the best way to do this is to set a 5-year fixed volume (a “cap“) on annual consumption based on an average of how much water has been available in the recent 5 years, and then allocate portions or shares of that volume to each user (i.e., to each geopolitical unit, community, or individual water user). The cap volume needs to be updated every five years. I like a 5-year adaptive cap because it gives water users enough time to plan and implement changing allocations while not allowing any overconsumption to cause severe problems before readjusting the cap.
  • Principle #6 acknowledges the reality that water conservation measures can be costly for both rural and urban users, and can impact the profitability of farms. Subsidization of these expenses or losses will be essential in rebalancing these water systems for sustainability, enabling both urban and rural communities to transition to lower water use as rapidly as possible, and with least economic and social impact. The price tags may seem exorbitant or impossible at first blush, but the costs of continued unsustainable water use will be much, much greater.
  • Principle #7 requires investment in continuously monitoring reservoir, aquifer, and river levels, and enforcement of water allocations. One of the most important indicators of management performance is whether reservoir or aquifer levels or annual river flow volumes are declining. If this is the case, allocations need to be adjusted until balance returns.

Passing the Torch to a New Generation

Today is my retirement day.

In my Chasing Water book, I mused about the fact that when I was born in 1956, the western US was in the grips of one of the longest and most severe droughts in American history. It seems fitting to have spent my professional life focusing on water scarcity and environmental flows.

But I now find it quite depressing to acknowledge that our society has still not become any better at sustainable water management. Many river basins, including the three summarized above, are now facing their most dangerous crises.

When I was teaching water sustainability at the university level, I would point out to my students that in my birth year of 1956 virtually all of the Colorado River’s water was being consumed. Why we allowed greater and greater use of water in that river basin for another half-century continues to astonish and bewilder me to this day. Why is our species so incapable of recognizing clear and present dangers and so inept at responding accordingly?

But I leave you eternally hopeful. The students that I’ve taught, and the many younger adults I’ve met through my work in more than 40 countries, have the intellect and the passion to bend the arc of water management back towards sustainability, if we give them the chance. I urge them to take up this charge, to find ways to gain positions of authority and power to lead toward better days ahead.

I’ll leave these next generations with one bit of advice: The management of water cannot remain solely in the hands of hydrologists and engineers and economists. We need legions of young new professionals that understand social science, political science, behavioral science. And we need artists.

After all, managing water is about people, and the human spirit.

10 Big Wins for Rivers in 2025: A snapshot of our biggest river successes from this past year — Hannah Axtell (AmericanRivers.org)

December 19, 2025

Despite the escalating threats to rivers, this past year brought real progress worth celebrating. To highlight the positive strides being made across the country, we’ve curated a list of 10 exciting wins for rivers, community safety, people, and wildlife. From proposed Wild and Scenic protections for nearly 100 miles of the Gallatin and Madison rivers, to major investments in river restoration and wildfire resilience in California, and stronger permit safeguards for the Rappahannock River, 2025 proved to be a year of meaningful breakthroughs for waterways nationwide. 

In no particular order, here’s a snapshot of 10 of our biggest river wins of 2025: 

  1. Secured major wins for America’s Most Endangered Rivers® of 2025 

Our 2025 America’s Most Endangered Rivers® report ranked the Tijuana River #2 due to toxic pollution threatening border communities. This designation, developed with partners Surfrider Foundation and Un Mar de Colores, helped catalyze swift federal action. Within three months of the April report release, American Rivers and others were invited to meet with EPA Administrator Lee Zeldin in southern California, which helped build momentum for a landmark agreementbetween the United States and Mexico to address the ongoing public health crisis. This demonstrates how strategic advocacy, combined with persistent community leadership, drives solutions for rivers and their communities. 

The Rappahannock River’s designation as one of America’s Most Endangered Rivers® of 2025 brought crucial national attention to the threats facing Virginia’s longest free-flowing river. But this spotlight did more than raise awareness; it galvanized action that delivered tangible results. Working alongside our dedicated partners, The Friends of the Rappahannock, the Rappahannock Tribe, and the Southern Environmental Law Center, we achieved a significant victory for the river and the communities that depend on it. This collaborative effort secured permit changes for a proposed data center, banning industrial cooling withdrawals and reducing drought withdrawals by millions of gallons.

  1. Mobilized action to protect Public Lands and Roadless Areas 

Bipartisan public outcry over a disastrous sell-off provision in a massive tax and spending bill led to the protection of public lands and the rivers that flow through them. Victory was snatched from the jaws of defeat thanks to supporters like you

The Trump administration is looking to rescind the Roadless Rule, which protects clean water and wildlife habitat by preventing road construction and timber harvest on roughly 45 million acres of national forests. This would be a significant setback (100,000 river miles) to our goal of protecting one million miles of rivers. Our team is making sure decision makers understand the impacts to clean drinking water supplies and we are mobilizing our supporters (we’ve collected more than 10,000 signatures so far) in support of these important river protections.

  1. Safeguarding Montana’s Gallatin and Madison Rivers 

Rep. Ryan Zinke (MT) introduced the Greater Yellowstone Recreation Enhancement and Tourism Act (GYREAT Act) – Wild and Scenic legislation to protect nearly 100 miles of the Gallatin and Madison rivers and their tributaries in southwestern Montana. This legislation was developed through collaboration with American Rivers and our partners. If passed, these protections would create a vital corridor linking the rivers of Yellowstone National Park to the headwaters of the Missouri River.

  1. Defending healthy rivers and Tribal sovereignty 

American Rivers helped rally national, regional, and local partners in urging the Department of Transportation to protect aquatic connectivity programs — efforts that restore fish passage, reconnect rivers and wetlands, and replace outdated culverts and road crossings. The joint comment letter was signed by 140 groups — including Tribes, anglers, businesses, universities, research institutions, conservation organizations, community leaders, agencies, faith groups, and planners — all united for healthier, more connected waterways. 

Additionally, when the Department of Energy urged the Federal Energy Regulatory Commission to roll back its 2024 policy protecting Tribal sovereignty in hydropower permitting, American Rivers acted fast. Working with Tribal attorneys, Native networks, and partner organizations, we mobilized national opposition and filed formal comments — demonstrating our deep commitment to Tribal leadership and ensuring healthy rivers. We’ll continue working alongside Tribal partners to ensure these protections remain strong.

  1. Restoring mountain meadows in California 

American Rivers is a key member of The Sierra Meadows Partnership, a coalition of environmental organizations working together to restore 30,000 acres of mountain meadows by 2030. These meadows act as natural sponges that store water, improve drought resilience, and provide essential wildlife habitat. Through this collaborative effort, we successfully secured a $24.7 million block grant from the Wildlife Conservation Board to support our restoration work.

  1. Advanced critical protections for New Mexico’s waterways 

After naming New Mexico’s waterways #1 on America’s Most Endangered Rivers® of 2024 list, we’re celebrating significant wins across the state. In the Pecos watershed — home to elk, black bears, Rio Grande cutthroat trout, and generations-old acequia farms — the Department of Interior paused new mining claims across 165,000 acres while pursuing longer-term protections. Through advocacy with our partners, we helped secure Outstanding National Resource Waters protection for over 250 miles of rivers across five watersheds, including the Rio Grande. And now, Senator Heinrich (NM) and the All Pueblo Council of Governors are championing protection of the Caja del Rio — a 107,000-acre landscape along the Rio Grande and Santa Fe rivers that holds deep cultural significance for Puebloan and Hispanic communities while supporting diverse wildlife.

  1. Furthering community safety through dam awareness 

American Rivers spoke on panels and hosted webinars addressing the deadly threat of low head dams, generating hundreds of participants from across the dam removal and safety industries. A low head dam is a human-made structure that spans the full width of a river and is designed to allow water to continuously flow over it, creating a dangerous hydraulic and earning them the nickname “drowning machines.” Our educational workshops brought together leading experts to discuss solutions for addressing these public safety hazards while advancing river restoration solutions.

  1. Building momentum for dam removal across the Northeast 

American Rivers is celebrating a wave of funding that will free multiple rivers across the Northeast. We were awarded $220,000 to remove the Yopp Pond dam on the Fourmile River in Connecticut — the first barrier blocking this coastal river that drains to Long Island Sound. Fisheries biologists note this removal will be transformational for alewife runs in this critical watershed. Additionally, New Hampshire Fish and Game committed $150,000 to support two strategic dam removals: North Branch Gale dam in the Upper Connecticut River watershed and Mead Brook dam in the Contoocook River watershed. Both dams impact excellent cold-water habitat and are scheduled for removal in 2026. Additionally, the Davis Conservation Foundation granted $20,000 for our hydropower relicensing work in Maine.

  1. Defended Idaho’s Salmon River 

Along with our partners at Advocates for the West and coalition members in Idaho, American Rivers and our Action Fund filed a lawsuit against the Forest Service to prevent a massive open-pit gold mine at the headwaters of the South Fork Salmon River. This important waterway is a national treasure that provides critical spawning habitat for the longest-distance, high-elevation salmon migration on Earth, as well as world-class whitewater recreation and fishing. It has been listed as one of America’s Most Endangered Rivers® for three consecutive years.

  1.  Improved wildfire resilience in California 

American Rivers and our partner, Terra Fuego Resources Foundation, completed prescribed fire burns on 160 acres as part of a 570-acre fuel reduction and prescribed fire project — a critical effort to protect the South Yuba River and the communities of Nevada City and Grass Valley from catastrophic wildfire. In a major boost for river restoration, the California Wildlife Conservation Board approved nearly $5 million to launch the Pickel Meadow Restoration Project on the West Walker River. Construction begins this summer, marking an exciting next chapter for this important watershed.

Longtime public servant and former state senator died December 10, 2025 at 94

Lewis H. Entz was one of those public servants who never stopped serving. The former state legislator was revered up until his death, which came Wednesday evening, December 10, 2025. He was 94.

Entz was Mr. San Luis Valley. Born in Monte Vista and a farmer from Hooper, he represented the Valley in the Colorado House of Representatives for 16 years from 1982-98, and then in 2001 became state senator when he succeeded then-State Sen. Gigi Dennis following her resignation. 

He served in the state senate until 2006, and before any of that served for 14 years as an Alamosa County Commissioner.

“Five young Republicans talked me into running,” he told the Monte Vista Journal of how he got his start in politics.

Even out of office, Entz maintained his public service. Every year he was part of the annual Alamosa Veterans Day Parade as a former U.S. Marine who fought in the Korean War, and was a regular in the Ski-Hi Stampede Parade and all the parades and gatherings across the Valley. 

He was part of the Early Iron Club, which afforded him the opportunity to display his passion of restoring and maintaining vehicles. His baby was his 1943 Ford jeep, which he drove in all the parades year after year.

One of his final meetings was at breakfast in November with state Sen. Cleave Simpson of Alamosa, and former state senators Gigi Dennis and Larry Crowther. It was an occasion to gather together all the former Republican state senators who have represented the San Luis Valley to mingle and enjoy each other’s company.

“So glad we had breakfast together a few weeks ago. Such an honorable public servant, I am so proud to have known him and work with him on important Valley issues,” Simpson said.’

The tributes to Entz on Alamosa Citizen Facebook, which first reported the news of his death, are extensive. “Lew was a great fellow and solid friend of the Upper Arkansas Water Conservancy District. He will be missed,” wrote Ralph Scanga. Wrote Ronald W. Jablonski Jr., “Enjoyed working with Mr. Entz during my time at Rio Grande NF. He was a fair and honest champion for his SLV constituents.”

The lasting question of his legacy is the H in his name, which he always used in life and on the extensive number of legislative bills he authored.

“When my twin sister and I were brought home from the hospital, we went by Homelake. It’s been in my mind ever since,” he told a magazine writer in 2004.

Lewis H. Entz is preceded in death by his wife, Lorie Entz, who passed away Sept. 7, 2014. They married on Nov. 24, 1952. 

He is survived by his wife, Kathryn “Kitty” Bigley-Entz. Funeral arrangements and obituary are pending through Rogers Family Mortuary.

Water across the West at risk as President Trump targets national monuments: A new study found that about 83% of water passing through public lands uses monument designation for its only protection — Wyatt Myskow (High Country News)

This story was originally published bInside Climate News and is republished here through a partnership with Climate Desk.

The 31 national monuments designated since the Clinton administration, which could be downsized as the Trump administration pushes to open more public lands to extractive industries, safeguard clean water for millions of Americans, according to a new analysis from the Center for American Progress.

Using geospatial data to quantify the miles of rivers and watersheds within the studied national monument boundaries, as well as the number of users who depend on that water, the report found that the water supplies for more than 13 million Americans are directly provided by watersheds within or downstream of these national monuments. About 83% of the water passing through these public lands has no other protection besides the monument designations, it found.

National monuments protect more than 21,000 miles of waterways across the U.S., nearly twice as much waterway mileage as the National Wild and Scenic Rivers System, the analysis also determined.

The report comes as the Trump administration weighs downsizing or revoking the designation of  some national monuments.

In March, the Trump administration announced it would eliminate California’s Chuckwalla and Sáttítla Highlands national monuments before removing language from a White House fact sheet announcing that decision. The following month, The Washington Post reported that the administration was considering downsizing or eliminating six national monuments, and in June, the U.S. Department of Justice issued an opinion that the president has the power to rescind national monument designations, backtracking on a decades-old determination on the matter.

During Trump’s last term, Bears Ears and Grand Staircase-Escalante national monuments, established by the Obama and Clinton administrations, respectively, were shrunk to fractions of their original sizes, but they were restored by President Joe Biden after he took office.

If national monuments are downsized or eliminated, the areas surrounding a waterway will lose protections from extractive industries, including oil and gas drilling, mining and grazing. Contamination from those industries could seep into streams and, in turn, rivers. Those industries also use water, sometimes vast amounts in arid regions, further reducing the supply that flows to nearby communities. (In certain cases, some mining and grazing are already permitted on national monument lands, but the activities are limited in scale and more regulated than they are outside the monuments.)

“Landscapes and waterways go hand in hand,” said Drew McConville, a senior fellow for conservation policy at the Center for American Progress and a co-author of the report. “The clean water depends on what comes into them from natural lands … Just protecting the wet stuff itself doesn’t guarantee that you’re keeping [water] clean and durable.”

The portion of historically marginalized communities living within the watersheds of the national monuments is greater than the average for watersheds nationally, it found. Twenty-three of the monuments studied are also found in regions expected to face water shortages due to climate change in the coming decades, making the arid regions downstream even drier.

Grand Staircase-Escalante National Monument, for example, protects 2,517 miles of waterways, according to the analysis, and nearly 90% of the watersheds within the monument are expected to see declines in their water levels. The monument straddles the Upper and Lower Colorado River Basins, with the Paria and Escalante rivers flowing within its boundaries and Lake Powell, the nation’s second-largest reservoir, just to its south. 

The monument is often thought of as a sparse, arid region, which it is, said Jackie Grant, the executive director of Grand Staircase Escalante Partners, a nonprofit focused on protecting the monument that has spent $11 million to protect the Escalante River watershed and all its tributaries. It remains vital to the Colorado River System, which millions of people in the Southwest rely on. Grand Staircase-Escalante helps slow water from the Paunsaugunt Plateau in Bryce Canyon National Park, much of which starts as snowpack in the park before melting and flowing downstream. 

“People don’t think of water when they think of Grand Staircase-Escalante National Monument,” Grant said. “So when we can bring this view of water and how important it is to the protection of the monument, it helps us put another building block in our case for supporting the monument, because not only is it important for the animals, the native plants, the geology and the paleontology, water plays a huge role in the monument, and the monument protects the water itself.”

The Antiquities Act of 1906 was signed into law by Theodore Roosevelt, for “… the protection of objects of historic and scientific interest” through the designation of national monuments by the President and Congress. National monuments are one of the types of specially-designated areas that make up the BLM’s National Conservation Lands. Some of the earliest national monuments included Devils Tower, the Grand Canyon, and Death Valley. They were initially protected by the War Department, then later by the National Park Service. More recently, the BLM and other Federal agencies have retained stewardship responsibilities for national monuments on public lands. In fact, the BLM manages more acres of national monuments in the continental U. S. than any other agency. This includes the largest land-based national monument, the Grand Staircase-Escalante National Monument in Utah featured here. National monuments under the BLM’s stewardship have yielded numerous scientific discoveries, ranging from fossils of previously unknown dinosaurs to new theories about prehistoric cultures. They provide places to view some of America’s darkest night skies, most unique wildlife, and treasured archaeological resources. In total, twenty BLM-managed national monuments, covering over five million acres, are found throughout the western U. S. and offer endless opportunities for discovery. Photos and description by Bob Wick, BLM.

Stretching across 1.87 million acres of public land, Grand Staircase-Escalante National Monument is one of the country’s most expansive national monuments, protecting scores of wildlife as well as archeological resources in southern Utah. But a nine-billion-ton coal deposit is buried in the center of the monument along with deposits of minerals, including uranium and nickel. The Trump administration has long touted boosting the country’s coal production, and has established a pro-mining agenda this year.

“It’d be very easy to contaminate either one of those rivers if mining were to take place in the center section of the monument,” Grant said. 

Margaret Walls, a senior fellow at Resources for the Future who has studied national monuments but was not part of this study, said national monuments are designated to protect cultural or historical landmarks, and it can be forgotten that they can also serve purposes like safeguarding water. Though she noted that even if monument protections are loosened, the areas remain federal lands, and their changes in status do not guarantee they will be developed. 

“We don’t protect waterways the way we do land,” Walls said, “we’re going to get those water benefits by protecting the land.”

January date scrapped in favor of June 29, 2026, after ‘key witness unavailability’ — four years after Fourth Amended Plan of Water Management was first approved by Subdistrict 1 and with the unconfined aquifer still in a historic decline

The San Luis Valley’s highly-anticipated district water court case — the water trial of this century if you will — originally scheduled to last five weeks beginning in January has been pushed back six months to the summer of 2026 due to the departure of a key witness in the fallout from a series of contentious October emails.

The Fourth Amended Plan of Water Management by Subdistrict 1 in the Rio Grande Water Conservation District has lived a precarious life without ever being implemented, going back to 2022 when it was originally crafted by subdistrict managers and January 2023 when it was adopted by Rio Grande Water Conservation District board.

Later came approval by the state engineer, and then after objections were filed against the new amended plan, Colorado Water Court Division 3 Judge Michael Gonzales set a trial date to commence on Jan. 5, 2026, and to last five weeks.

That is, until the week before Thanksgiving when Gonzales scrapped the January date in favor of June 29, 2026, some four years after the plan was first approved at the subdistrict level and the unconfined aquifer still in a historic decline. The judge did so after a series of emails sent by a key expert witness for the main objectors to the plan surfaced.

The effect is that a new plan to recover the Rio Grande’s unconfined aquifer, which has been approved at the local and state levels but still requires sign-off from district water court, remains  in limbo.

Following filings by the Northeast Water Users Association and Sustainable Water Augmentation Group requesting a six-month continuance to the start of the trial, and the Rio Grande Water Conservation District and state Division of Water Resources objecting to the request, Gonzales ruled the two main objectors challenging the new aquifer recovery plan had good reason to ask for a six-month continuance after Taylor Adams, an environmental and water resources engineer for Hydros Consulting in Boulder, resigned from the case due to “personal and family circumstances.” 

Adams was set to challenge the Subdistrict 1 water plan on a variety of engineering fronts until a series of emails he sent in October to State Engineer Jason Ullman and Senior Assistant Attorney General Preston Hartmann came to light. In one email, he tells Ullman, “Also, GFY.” In another, he emails that he is “no longer interested in anything other than publicly exploding the rampant corruption at DWR and the AG Office.” 

And in an email sent Sunday, Oct. 19, to Attorney General Phil Weiser, Adams writes, “We haven’t met, but I understand that you’re running for governor of Colorado. You should know that if you continue this pursuit without addressing the persistent and laughable perjury that has been carried out in your name by Preston Hatman (sic) and Jason Ullman, you will be the subject of my attention throughout your campaign…”

The Rio Grande Water Conservation District asked Gonzales not to delay the water court proceedings due to the urgency to recover the unconfined aquifer and the lack of “credible evidence that demonstrates that Mr. Adams is unavailable. Rather, they now assert that he ‘should not be pressured into returning to the case at the risk of further harm to his mental health.’”

“In any event,” district water attorneys argued in their objection to a trial delay, “none of this changes the fact that the unconfined aquifer is still over 1.3 million acre-feet below the water levels measured in 1976, and more than 830,000 acre-feet below the water levels previously determined by this Court and the Colorado Supreme Court to be sustainable.”

Subdistrict 1 is home to the San Luis Valley’s richest crops of potatoes, barley and alfalfa. Without recovery of the shallow aquifer, the state is threatening mass shut down of groundwater pumping wells and requires both a master plan and annual replacement plans to show recovery efforts.

The subdistrict’s proposed Fourth Plan of Water Management is its most drastic effort yet to meet the state’s orders. The new plan, crafted in 2022 and adopted by the Rio Grande Water Conservation District in January 2023, is designed to “match the amount of groundwater pumping to the amount of water coming into the subdistrict.”

It does this through a 1-to-1 augmentation, meaning for every acre-foot of water used, an acre-foot has to be returned to the unconfined aquifer through recharging ponds. The amended plan relies on covering any groundwater withdrawals with natural surface water or the purchase of surface water credits.

Farmers in the subdistrict have expressed support for the plan, which includes a $500 per acre-foot overpumping fee that farmers would pay if they exceed the amount of natural surface water tied to the property in their farming operations. 

Objections are coming from farmers who do not have natural surface water coming into their property and around the steep fee for purchasing surface water credits from a neighboring operation to offset groundwater pumping irrigation. Both proponents and opponents of the plan say the $500 per acre-foot overpumping fee could put farmers who rely on groundwater pumping out of business.

The five-week water trial will sort through these issues in much more granular detail. With the trial date pushed back six months, any new strategy to recover the Valley’s ailing aquifer will shift into 2027 at the soonest.

November 27, 2025

Down the Stanley Road looking north in central Alamosa County are the massive solar panels that offer an unusual but common skyline in the high mountain desert west of Mosca. In the foreground of the solar structures, on 480 acres of degenerated land, is a grand new experiment by the Colorado Land Board that promises to offer new insights into carbon, the Valley’s soil, and the growing but complicated “carbon market.”

In September the state land board inked a partnership with Land & Carbon Inc., a carbon project development company, to revegetate and restore the land under an initial 15-year partnership, and then a 40-year monitoring period to determine long-term success.

This is the first contract of its kind in the Valley, but it definitely won’t be the last. With more land and water being retired from irrigation every year, the question of how to revegetate only becomes more urgent. Revegation helps not just to improve carbon sequestration, but also to prevent dangerous dust-bowl conditions that threaten an increasingly dry Valley. The water on the Stanley Road property was retired to the Rio Grande Water Conservation District in 2024, and the partnership has committed to using only the allotted 18 inches of water over the first 3 years for revegetation. This project will illuminate the possibilities for revegetation in the Valley, and is likely to lead the way for more innovative partnerships and projects focused on both land restoration and carbon sequestration in the coming years.

The Colorado State Land Board manages lands that were granted to the state in a public trust from the federal government back in 1876. It operates as the second-largest land owner in the state, holding 2.8 million acres of surface land and 4 million acres of subsurface assets. Its land management practices aim to both steward the land and produce reasonable and consistent income, a majority of which gets distributed to the Colorado Department of Education’s Building Excellent Schools Today (BEST) program. 

The Land Board established an ecosystem services program, focused on generating revenue from nontraditional products, like wetland and carbon credits, as opposed to more traditional products like agriculture, grazing, mining, oil and gas, hunting, recreation and renewables. A few years ago, through this program, the Land Board started exploring the prospect of carbon sequestration and carbon credits.

“We hired a group of consultants to help us enter this market. It’s new and not well understood by most people. It’s kind of on the leading edge of being developed, what we sometimes call an emerging market,” said Mindy Gottsegen, the State Land Board’s Stewardship and Ecosystem Services manager.  

The carbon market has emerged as a viable way to simultaneously restore damaged lands, while generating valuable revenue. While there are government regulations around carbon emissions and compliance with certain environmental standards, the carbon market is an entirely voluntary system that operates without large government oversight. Companies buying and selling carbon credits can join the market, and participate, as long as they meet certain standards, set by third-party organizations.

While it is a complicated system, this is generally how it works for soil carbon credits in the Valley: Every piece of land has some amount of carbon in the soil because plants take in CO2 from the atmosphere, photosynthesize, and store it. Through plant roots, and the decay of other organic matter, the soil ends up holding on to a certain amount of carbon. Different land management practices can increase or decrease the amount of carbon sequestered. 

To quantify carbon sequestration and sell credits, verified companies (or land owners) must first establish a baseline carbon measurement. Then, carbon gains are estimated over time using a combination of measurements and modeling. These numbers are reviewed, and based on the additional amount of carbon stored, carbon registries issue a proportionate amount of carbon credits. These credits can be sold on the market to entities looking to offset their carbon emissions. The revenue from carbon credits helps to fund and sustain carbon sequestration and land restoration projects.

“The Biological Carbon Program framework that our board approved in April of this year was kind of saying ‘This is how we’re going to get involved in the carbon market,’” said Gottsegen. 

The program allows agricultural and land lessees to partner with board-approved Qualified Project Developers (QPDs) to create and implement restorative project plans. These companies work as the middle man between land owners and the carbon market, helping to make successful and sustainable changes, while also navigating the approval and acquisition of carbon credits.


Enter Land & Carbon Inc. Founded by Dave Lawrence in 2023, Land & Carbon is an innovative project development company, restoring highly degraded lands with low-cost, science-driven solutions. The company works to regenerate and revegetate land while offsetting and storing CO2 in the soil, using carbon credits to help pay for the projects.

“I used to — well I still do — drive around the country quite a bit. I’ve observed just how much degraded and barren land there is, without healthy crops or native vegetation  — brown trampled land all around the country,” said Lawrence. 

Lawrence had previously served as both the chairman of the Yale Climate & Energy Institute and the executive director of the Salk Institute Harnessing Plants Initiative. In these roles, he was actively involved in carbon projects, and realized that reducing atmospheric carbon would require more than just emissions reduction.

“I recognized that there were a number of different solutions available, and that they could be used in combination,” said Lawrence. “I started Land & Carbon with this idea that we would use a combination of practices, and collaborate with communities, ranchers, farmers, land holders, and experts — local, regional, national, and global — pulling all of this together to do the best job that we could restoring degraded land, and at the same time taking carbon out of the atmosphere.”

A significant amount of the degraded land across the West is largely agricultural and sits with different state land boards. Land & Carbon reached out to the Colorado State Land Board with hopes of collaborating to regenerate these lands in a way that was mutually successful, taking advantage of best practices to sequester carbon, restore ecosystem health, and help fund the state’s public education system. 

Land & Carbon got approved as the Land Board’s fourth QPD in August and the deal, officially titled Grassland Carbon Ecosystem Services Production Lease, ES 117611, came soon after.

Of the land in the State Land Board’s portfolio, the Stanley Road property was selected because of a combination of factors. The property consists of 480 acres, in between Stanley Road, the 105, and the 106. It sits within Subdistrict 1, and its water rights, all groundwater access and wells, were sold to the Rio Grande Water Conservation District in December of 2024. This means moving forward there are severe limitations to the amount of water that can be used to revegetate. The land is highly degraded from decades of agricultural use, and has been barren for years. In that time, a takeover of invasive weeds, along with harsh soil and climate conditions, have prevented any sort of natural recovery.

This property had been a challenge for the Land Board, because of the amount of damage. While this level of degradation can be seen as a deterrent for other QPDs, these types of highly degraded properties are exactly what Land & Carbon seek out. When the Land Board asked if it would be interested in taking on the challenge, the answer was a resounding “Yes.” 

In any project for Land & Carbon, the first steps include a “scope and discovery” research deep dive, to better understand what has already been done, and learn how its efforts will be situated in the broader context of work in the region. In the Valley, this means looking at CSU Extension information, published papers, USDA, State Land Board and Conservation District data, conducting their own boots-on-the-ground field visits, and also engaging with the community. All of it is pulled together to assess initial land characteristics. 

“We’re a big believer in talking with people and learning from people who are actually doing the work. So we participated in workshops, convened by Colorado State, that allowed us to get to know different individuals and people and groups who were already doing things,” said Lawrence. “We don’t believe we have the corner on the market on all expertise. We really try to tap into as much local knowledge as we can, as to what has worked, what hasn’t worked and why.”

After that, an exhaustive evaluation of all available data and information is done, pulling in literature, field data, and models to create an initial plan, taking into consideration resource availability and supplies. Then they take baseline measurements to determine the starting amount of carbon in the soil that is crucial to then quantify improvements and carbon credits. 

The Stanley Road project is still in these early stages, and they are working to collect data, determine land characteristics, and establish a carbon baseline, before considering different solutions and strategies. 

“We tailor our solutions to the land. Not everything grows everywhere and not all grazing practices work everywhere. So how can we tailor the best combination to this land?” said Lawrence.

The next steps will come in the spring, at the start of the growing season, when Land & Carbon plans to establish what it has trademarked as Innovation Sites. These five- to 20-acre patches on the property are used to test out new ideas and different combinations, seed mixes, and technologies, in order to learn what works best on this specific land. These experimental sites will run for three to five years, after which the best, most successful techniques will be used on the larger property. Many of the tests will not work, but some will, and those are what get implemented broadly.

In the years to come, these plans will continue to develop. Final decisions around irrigation, and how to use the 18 inches of water allocated for the first 3 years of the project, have not yet been made. Nor have more definitive restoration plans, though in the press release by the Land Board, it was stated that the property is expected to support regenerative grazing within four to eight years. 

The project is estimated to sequester greater than 10,000 metric tonnes of CO2 in the first 15 years, which is when the initial contract ends. This will be followed by a 40-year monitoring period to ensure the permanence of the soil carbon storage.


With the state of water in the Valley, and efforts to retire agricultural land for water conservation purposes, the amount of land in need of revegetation and restoration will only continue to grow over the next few years. 

Both the State Land Board and Land & Carbon expressed interest in expanding the reach of this project and methodology, once it has been established. But that will take time. 

“I always think it’s good to try to do one thing very well, and to kind of get a proof point. We are very focused on this property, and of course we would love to work with others as we move along in this, and show what we have going,” said Lawrence.

“We’re just getting started. The first few take extra time, but we’re hoping that once we get these few under our belt, we’ll be able to expand,” said Gottsegen. “Hopefully we can continue to build the carbon program with more leases in the coming years.”

Lawrence emphasized that Land & Carbon aims to make this project the template for affordable, quality land regeneration using carbon credits, that will work for people in the Valley.

“The idea is that what we learn, we share. We can serve as just advisors if that’s what somebody who has all the capabilities wants, and there’s a ton of people with capabilities, or we can actually do the work,” said Lawrence. “I think we all know the challenges that we face with water in the San Luis Valley. It’s important that we take whatever we learn, in collaboration with others, and work with them to try to implement this at scale.”

🥵 Aridification Watch 🐫

The Colorado River and its woes tend to get all of the attention, but the Southwest’s “other” big river, the Rio Grande, is in even worse shape thanks to a combination of warming temperatures, drought, and overconsumption. That’s become starkly evident in recent years, as the river bed has tended to dry up earlier in the summer and in places where it previously had continued to carry at least some water. Now Brian Richter and his team of researchers have quantified the Rio Grande’s slow demise, and the conclusions they reach are both grim and urgent: Without immediate and substantial cuts in consumption, the river will continue to dry up — as will the farms and, ultimately, the cities that rely on it.

The Rio Grande’s problems are not new. Beginning in the late 1800s, diversions for irrigation in the San Luis Valley — which the river runs through after cascading down from its headwaters in the San Juan Mountains — sometimes left the riverbed “wholly dry,” wrote ichthyologist David Starr Jordan in 1889, “all the water being turned into these ditches. … In some valleys, as in the San Luis, in the dry season there is scarcely a drop of water in the riverbed that has not from one to ten times flowed over some field, while the beds of many considerable streams (Rio la Jara, Rio Alamosa, etc.) are filled with dry clay and dust.”


Rio Grande Streamflow Mystery: Solved? — Jonathan P. Thompson


San Luis Valley farmers gradually began irrigating with pumped groundwater, allowing them to rely less on the ditches (but causing its own problems), and the 1938 Rio Grande Compact forced them to leave more water in the river. While that kept the water flowing through northern and central New Mexico, the Rio Grande’s lower reaches still occasionally dried up.

Then, in the early 2000s, the megadrought — or perhaps permanent aridification — that still plagues the region settled in over the Southwest. [ed. emphasis mine] Snowpack levels in the river’s headwaters shrank, both due to diminishing precipitation and climate change-driven warmer temperatures, which led to runoff and streamflows 17% lower than the 20th century average, according to the new study. And yet, overall consumption has not decreased.

“In recent decades,” the authors write, “river drying has expanded to previously perennial stretches in New Mexico and the Big Bend region. Today, only 15% of the estimated natural flow of the river remains at Anzalduas, Mexico near the river’s delta at the Gulf of Mexico.” Reservoirs, the river’s savings accounts, have been severely drained to the point that they won’t be able to withstand another one or two dry winters. As farmers and other users have increasingly turned to groundwater pumping, aquifers have also been depleted. The situation is clearly unsustainable.

Something’s gotta give on the Rio Grande, and while we may be tempted to target Albuquerque’s sprawl, drying up all of the cities and power plants that rely on the river wouldn’t achieve the necessary cuts.

Source: “Overconsumption gravely threatens water security in the binational Rio Grande-Bravo basin” by Brian Richter et al.

It will come as little surprise to Western water watchers that agriculture is by far the largest water user on the Rio Grande — taking up 87% of direct human consumption — and that alfalfa and other hay crops gulp up the lion’s share, or 52%, of agriculture’s slice of the river pie. This isn’t necessarily because alfalfa and other hays are thirstier than other crops, but because they are so prevalent, covering about 433,000 acres over the entire basin, more than four times as much acreage as cotton.

Source: Overconsumption gravely threatens water security in the binational Rio Grande-Bravo basin

This kind of math means farmers are going to have to bear the brunt of the necessary consumption cuts — either voluntarily or otherwise. In fact, they already have: Between 2000 and 2019, according to the report, Colorado lost 18% of its Rio Grande Basin farmland, New Mexico lost 28%, and the Pecos River sub-basin lost 49% (resulting in a downward trend in agricultural water consumption). Some of this loss was likely incentivized through conservation programs that pay farmers to fallow their fields. But it was also due to financial struggles.

Yet even when farmers are paid a fair price to fallow their fields there can be nasty side effects. Noxious weeds can colonize the soil and spread to neighbors’ farms, it can dry out and mobilize dust that diminishes air quality and the mountain snowpack, and it leaves holes in the cultural fabric of an agriculture-dependent community. If a field’s going to be dried up, it should at least be covered with solar panels.

Another possibility is to switch to crops that use less water. This isn’t easy: Farmers grow alfalfa in the desert because it’s actually quite drought tolerant, doesn’t need to be replanted every year, is less labor-intensive than other crops, is marketable and ships relatively easy, and can grow in all sorts of climates, from the chilly San Luis Valley to the scorching deserts of southern Arizona.


Alfalfaphobia? Jonathan P. Thompson


Still, it can be done, as a group of farmers in the San Luis Valley are demonstrating with the Rye Resurgence Project. This effort is not only growing the grain — which uses less water than alfalfa, is good for soil health, and makes good bread and whiskey — but it is also working to create a larger market for it. While it’s only a drop in the bucket, so to speak, this is the sort of effort that, replicated many times across the region, could help balance supply and demand on the river, without putting a bunch of farmers out of business.

Oh, and about that other river? You know, the Colorado? Representatives from the seven states failed to come up with a deal on how to manage the river by the Nov. 15 deadline. The feds had mercy on them, giving them until February to sort it all out. I’m not so optimistic, but we’ll see. Personally, I think the only way this will ever work out is if the Colorado River Compact — heck, the entire Law of the River — is scrapped, and the states and the whole process is started from scratch, this time with a much better understanding of exactly how much water is in the river, and with the tribal nations having seats at the table.


⛏️ Mining Monitor ⛏️

There are a bunch of wannabe uranium mining companies out there right now, locating claims and acquiring and selling claims and touting their exploratory drilling results. But there are only a small handful of firms that are actually doing anything resembling mining. One of them is the Canada-based Anfield, which just broke ground on its Velvet-Wood uranium mine in the Lisbon Valley, even without all of the necessary state permits. 

Now Anfield says it has applied for a Colorado permit to restart its long-idle JD-8uranium mine. The mine is on one of a cluster of Department of Energy leases overlooking the Paradox Valley from its southern slopes, and was previously owned and operated by Cotter Corporation. The mine has not produced ore since at least 2006. Anfield says it will process the ore at its Shootaring Mill near Ticaboo, Utah, which has yet to get Utah’s green light.

November 20, 2025

Research published Thursday says the situation arguably is worse than challenges facing the Colorado River, another vital lifeline for western U.S. states that have yet to chart a course for how best to manage that dwindling resource. Without rapid and large-scale action on both sides of the border, the researchers warn that unsustainable use threatens water security for millions of people who rely on the binational basin. They say more prevalent drying along the Rio Grande and persistent shortages could have catastrophic consequences for farmers, cities and ecosystems…The study done by World Wildlife Fund, Sustainable Waters and a team of university researchers provides a full accounting of the consumptive uses as well as evaporation and other losses within the Rio Grande-Bravo basin. It helps to paint the most complete — and most alarming — picture yet of why the river system is in trouble…The research shows only 48% of the water consumed directly or indirectly within the basin is replenished naturally. The other 52% is unsustainable, meaning reservoirs, aquifers and the river itself will be overdrawn…

Irrigating crops by far is the largest direct use of water in the basin at 87%, according to the study. Meanwhile, losses to evaporation and uptake by vegetation along the river account for more than half of overall consumption in the basin, a factor that can’t be dismissed as reservoir storage shrinks…The irrigation season has become shorter, with canals drying up as early as June in some cases, despite a growing season in the U.S. and Mexico that typically lasts through October. In central New Mexico, farmers got a boost with summer rains. However, farmers along the Texas portion of the Pecos River and in the Rio Conchos basin of Mexico — both tributaries within the basin — did not receive any surface water supplies…The analysis found that between 2000-2019, water shortages contributed to the loss of 18% of farmland in the headwaters in Colorado, 36% along the Rio Grande in New Mexico and 49% in the Pecos River tributary in New Mexico and Texas.  With fewer farms, less water went to irrigation in the U.S. However, researchers said irrigation in the Mexican portion of the basin has increased greatly.

November 20, 2025

In November 2023, I stopped by the office of Cleave Simpson, then (and still now, at least for a brief time more), the general manager of the Rio Grande Water Conservancy District.

There, in Alamosa, he shared with me his observation that the Rio Grande during the 21st century has had water declines parallel to those of the Colorado River.

Both rivers originate in Colorado, and neither river has been able to deliver the water assumed by any number of diversion projects. Problems began in the 20th century but have intensified greatly in the 21st century because of drought but also rising temperatures.

The Rio Grande has had 17% reduced flows since 2000. The Colorado River flows have declined 20%.

Of the two rivers, the Rio Grande is longer, at 1,900 miles but carries less water, 9.1 million acre-feet/year. The Colorado flows 1,450 miles and has been carrying an average 15.4 million acre-feet. Neither river has delivered water into oceans with any reliability in decades.

Despite these parallels, the Colorado has received far more attention, as is pointed out in a new report by Brian Richter of the World Wildlife Fund and nine others from academic institutions in Arizona, California, and other states.

Why is that? The Colorado provides drinking water for about 40 million people compared to 15 million for the Rio Grande. In irrigated agriculture, it’s a similar story: 22,300 square kilometers in the Colorado River Basin vs. 7,800 square kilometers in the Rio Grande.

“However, the water crisis facing the Rio Grande Basin is arguably more severe and urgent than the Colorado River Basin,” Richter and his colleagues contend. They argue for some rethinking and institutional alignments to help ratchet water use down to sustainable levels.

The study is the first full accounting of how water is consumed across the entire Rio Grande Basin. Mexico calls it the Rio Bravo.

Doesn’t Colorado also have a strong accounting system, as necessary to meet requirements of the 1938 compact among states that share the Rio Grande?

Yes, says Richter. However, he adds a “but.” He reports difficulty in getting estimates of  how much water is being consumed by each sector and by each crop. He believes he has succeeded.

“To my knowledge, nobody has laid out the numbers at the level of clarity and accuracy that we were able to accomplish,” he said.

Another major contribution of the paper is the estimation of the degree to which water consumption is unsustainable, he said.

“We estimate that 11% of water consumption in Colorado is unsustainable. Natural replenishment from snowmelt runoff, precipitation, and groundwater recharge supplies only 89% of the water being consumed; the remainder (deficit) is being met by depleting groundwater.”

“The Rio Grande basin is at a tipping point, and everyone needs to be part of the solution,” said Enrique Prunes, a co-author and the World Wildlife Fund Rio Grande manager. “These findings will help us rethink how we manage water to secure a future for everyone.”

Agriculture uses 99.9% of the water in Colorado’s San Luis Valley and 87% in the basin altogether.

Dramatic declines in reservoir storage illustrate the scope of problem. Altogether, 12% of reservoir storage has been lost in the 21st century. The decline is most severe in New Mexico, where 71% less water was stored at the end of 2024 compared to 2002.

Groundwater depletion has been even more drastic. Roughly 15 times more groundwater has declined compared to surface storage. The two are coupled. As surface water supplies decline, groundwater mining grows.

Draining of aquifers has been a particularly vexing problem, as was explained in a story published in Headwaters magazine in June (and published in installments at BigPivots.com during July). See in particular 20th century expansion and 21st century realities in the San Luis Valley

“In the San Luis Valley of Colorado, diminished river flows and aquifer recharge have led to continued over-pumping, causing aquifers levels to decline,” Richter and his team write. “The Colorado state engineer has threatened to shut off hundreds of groundwater wells if the aquifer supporting irrigated farms cannot be stabilized.”

The San Luis Valley is famous for its potatoes as well as the barley to make Coors beer, but potatoes use just 7% of the water and barley 9%. The vast majority of water in the valley produces feedstocks for livestock: 47% for alfalfa, 27% for other hay, and 6% for pasture lands.

The study finds that groundwater in the San Luis Valley has been depleted at a rate of 89,179 acre-feet/year, equivalent to 11% of the annual average of direct water consumption in the valley.

What can be done? Large cities have done more with less. Albuquerque’s population grew 40% while its water use declined by 17%. However, municipal and commercial water consumption account for only 7% of all direct consumption in the three-state and two-country basin.

Strategies for reducing consumption in irrigated agriculture have been proven but must be rapidly deployed at sufficient scale and financially sustained by governments, companies, and credit institutions to rebalance the basin’s water budgets, state, and binational levels.

At the same time, water shortages have contributed to the loss of 18% of farmland in the river’s headwaters in Colorado, 36% in New Mexico, and 49% in the Pecos River tributary in New Mexico and Texas.

Strategies being embraced to curb groundwater drafting in the closed basin of the San Luis Valley have been controversial. A key case is likely to go before the Colorado Supreme Court. In Mexico, cutbacks have led to violence. One protestor died.

The study points to several strategies that could reshape how water is used in the basins. These include restoring river habitats, adjusting dam operations to better support seasonal flows, improving water-sharing agreements, and helping farmers switch to crops that require less water.

That effort to encourage crop-switching has been underway in the San Luis Valley, but with successes only at the margins.

November 21, 2025

major new study on the nearly 1,900-mile long Rio Grande Basin — from the San Luis Valley into the Gulf of Mexico — shows a “severe water crisis emerging” with total reservoir storage in decline at around 4.24 million acre-feet or 26 percent of capacity.

The study brings together detailed water consumption estimates of surface and ground water use throughout the basin and concludes “a likely outcome will be continued loss of farmland due to financial insolvency from lowered crop production and other factors including the aging of farmers and lack of affordable farm labor,” without urgent action.

“Climate scientists have reframed the long-running drought as the onset of long-term aridification and are forecasting additional river flow diminishment of 16-28% in coming decades as the climate continues to warm,” the study notes.

The authors’ analysis shows that during 2000–2019, Colorado lost 18 percent of its farmland in the Upper Rio Grande Basin, New Mexico lost 28 percent along its Rio Grande sub-basins, and the Pecos River sub-basin lost 49 percent.

Further drying puts farmers and cities who rely on the Rio Grande in an “existential water crisis.”

Brian Richter, one of the authors of the study, says San Luis Valley farmers are central to the development and implementation of solutions for the rapidly drying Rio Grande given that “the vast majority of the direct human consumption of water in the SLV takes place on irrigated farms.”

Researchers estimate that the present level of over-consumption of both surface and groundwater in the Valley is approximately 11 percent. “That means that water consumption needs to be reduced by that percentage,” Richter said.

Richter is president of Sustainable Waters and senior freshwater fellow for the World Wildlife Fund. The two organizations teamed with researchers to provide a full accounting of the consumptive uses as well as evaporation and other losses within the Rio Grande Basin. 

The Rio Grande stretches nearly from the San Luis Valley through New Mexico, El Paso, Texas, and empties into the Gulf of Mexico. It provides drinking water for more than 4 million in Colorado, New Mexico and Texas, and 11 million people in Mexico, the study notes. More than 1.9 million acres of irrigated farmland is tied to the Rio Grande.

The study, “Overconsumption gravely threatens water security in the binational Rio Grande-Bravo basin,” relies on data from annual runoff volumes, municipal and commercial consumptive use estimates from the U.S. Geological Survey, and reservoir storage levels, among other data sets.

Snowmelt runoff has decreased 17 percent over the past 25 years, according to the report. At the same time, total direct water consumption has been increasing since 2000, largely due to increasing water usage by farmers in Mexico.

When comparing challenges of Colorado River users to the Rio Grande, researchers say the “water crisis facing the RGB is arguably more severe and urgent than the CRB,” given the fact groundwater in the San Luis Valley has been depleted at a rate of 89,000 acre-feet per year; New Mexico has a water debt to Texas; and Mexico has a mounting water debt to the U.S. under a 1944 treaty that is causing political tension between the two countries.

The Upper Rio Grande here at the end of 2025 is benefitting from heavy October rainsthat materialized across the southwest and provided a stopgap to what were some of the worst summer river flows ever recorded on the river.

Management of the Upper Rio Grande Basin will be back in the spotlight come January 2026 when Colorado Water Court Division Three takes up the Fourth Amended Plan of Water Management for Subdistrict 1 of the Rio Grande Water Conservation District. The new strategy calls for a groundwater overpumping fee of $500 per acre-foot any time an irrigator in Subdistrict 1 exceeds the amount of natural surface water tied to the property of their operation. The rule punishes farmers who do not have natural surface water coming into their fields but instead rely solely on groundwater pumping for their crops.

The whole point of the plan for the agricultural-rich area of the San Luis Valley is to let Mother Nature dictate the pattern of how irrigators in Subdistrict 1 restore the unconfined aquifer and build a sustainable model for farming in the future.

Richter credits Colorado and irrigators in the Valley for taking steps to address the Rio Grande. The proposed $500 fee for overpumping in Subdistrict 1, he says, “is going to set off a lot of change in the Valley, because many/most farmers won’t be able to continue producing the same crops they’ve been growing in recent years.”

“Colorado has definitely taken some important steps, and manages its water resources far better than New Mexico or Texas,” Richter says. “But Colorado still has not been able to reduce pumping to anywhere near the needed degree, so it’s no surprise the aquifer continues to decline.”

The study looks at crops grown along the Rio Grande and how agricultural fields account for 87 percent of direct water consumption. “Overall, agricultural consumption is nearly seven times the volume of all other direct uses combined.”

Alfalfa and grass hay – water-intensive crops that dominate the landscape in the Valley and in Northern and the Middle Rio Grande of New Mexico – account for nearly 45 percent of the irrigation water consumed along the Rio Grande Basin. A shift to less-intensive crops, as the Rye Resurgence Project advocates, and a moratorium on new wells in over-drafted areas of basin in New Mexico and Texas, are necessary first steps to addressing the Rio Grande’s challenges, according to researchers of the study.

“Potatoes might be one of the few crops that remain sufficiently profitable to persist in the Valley,” says Richter. “If those transitions to other crops or to permanent farmland retirement lead to reduced water consumption to the level needed (11 percent), there is hope that the (unconfined) aquifer can be rebalanced with natural replenishment. However, it will require a greater level of pumping reductions to enable the aquifer to recover to the level required by the state engineer.”
