On July 4, the broken remnants of a powerful tropical storm spun off the warm waters of the Gulf of Mexico so heavy with moisture that it seemed to stagger under its load. Then, colliding with another soggy system sliding north off the Pacific, the storm wobbled and its clouds tipped, waterboarding south central Texas with an extraordinary 20 inches of rain. In the predawn blackness, the Guadalupe River, which drains from the Hill Country, rose by more than 26 vertical feet in just 45 minutes, jumping its banks and hurtling downstream, killing 109 people, including at least 27 children at a summer camp located inside a federally designated floodway.

Over the days and weeks to come there will be tireless โ€” and warranted โ€” analysis of who is to blame for this heart-wrenching loss. Should Kerr County, where most of the deaths occurred, have installed warning sirens along that stretch of the waterway, and why were children allowed to sleep in an area prone to high-velocity flash flooding? Why were urgent updates apparently only conveyed by cellphone and online in a rural area with limited connectivity? Did the National Weather Service, enduring steep budget cuts under the current administration, adequately forecast this storm?

Those questions are critical. But so is a far larger concern: The rapid onset of disruptive climate change โ€” driven by the burning of oil, gasoline and coal โ€” is making disasters like this one more common, more deadly and far more costly to Americans, even as the federal government is running away from the policies and research that might begin to address it.

President Lyndon B. Johnson was briefed in 1965 that a climate crisis was being caused by burning fossil fuels and was warned that it would create the conditions for intensifying storms and extreme events, and this country โ€” including 10 more presidents โ€” has debated how to respond to that warning ever since. Still, it took decades for the slow-motion change to grow large enough to affect peopleโ€™s everyday lives and safety and for the world to reach the stage it is in now: an age of climate-driven chaos, where the past is no longer prologue and the specific challenges of the future might be foreseeable but are less predictable.

Climate change doesnโ€™t chart a linear path where each day is warmer than the last. Rather, science suggests that weโ€™re now in an age of discontinuity, with heat one day and hail the next and with more dramatic extremes. Across the planet, dry places are getting drier while wet places are getting wetter. The jet stream โ€” the band of air that circulates through the Northern Hemisphere โ€” is slowing to a near stall at times, weaving off its tracks, causing unprecedented events like polar vortexes drawing arctic air far south. Meanwhile the heat is sucking moisture from the drought-plagued plains of Kansas only to dump it over Spain, contributing to last yearโ€™s cataclysmic floods.

We saw something similar when Hurricane Harvey dumped as much as 60 inches of rain on parts of Texas in 2017 and when Hurricane Helene devastated North Carolina last year โ€” and countless times in between. We witnessed it again in Texas this past weekend. Warmer oceans evaporate faster, and warmer air holds more water, transporting it in the form of humidity across the atmosphere, until it canโ€™t hold it any longer and it falls. Meteorologists estimate that the atmosphere had reached its capacity for moisture before the storm struck.

The disaster comes during a week in which extreme heat and extreme weather have battered the planet. Parts of northern Spain and southern France are burning out of control, as are parts of California. In the past 72 hours, storms have torn the roofs off of five-story apartment buildings in Slovakia, while intense rainfall has turned streets into rivers in southern Italy. Same story in Lombok, Indonesia, where cars floated like buoys, and in eastern China, where an inland typhoon-like storm sent furniture blowing down the streets like so many sheafs of paper. Lรฉon, Mexico, was battered by hail so thick on Monday it covered the city in white. And North Carolina is, again, enduring 10 inches of rainfall.

There is no longer much debate that climate change is making many of these events demonstrably worse. Scientists conducting a rapid analysis of last weekโ€™s extreme heat wave that spread across Europe have concluded that human-caused warming killed roughly 1,500 more people than might have otherwise perished. Early reports suggest that the flooding in Texas, too, was substantially influenced by climate change. According to a preliminary analysis by ClimaMeter, a joint project of the European Union and the French National Centre for Scientific Research, the weather in Texas was 7% wetter on July 4 than it was before climate change warmed that part of the state, and natural variability alone cannot explain โ€œthis very exceptional meteorological condition.โ€

That the United States once again is reeling from familiar but alarming headlines and body counts should not be a surprise by now. According to the World Meteorological Organization, the number of extreme weather disasters has jumped fivefold worldwide over the past 50 years, and the number of deaths has nearly tripled. In the United States, which prefers to measure its losses in dollars, the damage from major storms was more than $180 billion last year, nearly 10 times the average annual toll during the 1980s, after accounting for inflation. These storms have now cost Americans nearly $3 trillion. Meanwhile, the number of annual major disasters has grown sevenfold. Fatalities in billion-dollar storms last year alone were nearly equal to the number of such deaths counted by the federal government in the 20 years between 1980 and 2000.

The most worrisome fact, though, may be that the warming of the planet has scarcely begun. Just as each step up on the Richter scale represents a massive increase in the force of an earthquake, the damage caused by the next 1 or 2 degrees Celsius of warming stands to be far greater than that caused by the 1.5 degrees we have so far endured. The worldโ€™s leading scientists, the United Nations panel on climate change and even many global energy experts warn that we face something akin to our last chance before it is too late to curtail a runaway crisis. Itโ€™s one reason our predictions and modeling capabilities are becoming an essential, lifesaving mechanism of national defense.

What is extraordinary is that at such a volatile moment, President Donald Trumpโ€™s administration would choose not just to minimize the climate danger โ€” and thus the suffering of the people affected by it โ€” but to revoke funding for the very data collection and research that would help the country better understand and prepare for this moment.

Over the past couple of months, the administration has defunded much of the operations of the National Oceanic and Atmospheric Administration, the nationโ€™s chief climate and scientific agency responsible for weather forecasting, as well as the cutting-edge earth systems research at places like Princeton University, which is essential to modeling an aberrant future. It has canceled the nationโ€™s seminal scientific assessment of climate change and risk. The administration has defunded the Federal Emergency Management Agencyโ€™s core program paying for infrastructure projects meant to prevent major disasters from causing harm, and it has threatened to eliminate FEMA itself, the main federal agency charged with helping Americans after a climate emergency like the Texas floods. It has โ€” as of last week โ€” signed legislation that unravels the federal programs meant to slow warming by helping the countryโ€™s industries transition to cleaner energy. And it has even stopped the reporting of the cost of disasters, stating that doing so is โ€œin alignment with evolving prioritiesโ€ of the administration. It is as if the administration hopes that making the price tag for the Kerr County flooding invisible would make the events unfolding there seem less devastating.

Given the abandonment of policy that might forestall more severe events like the Texas floods by reducing the emissions that cause them, Americans are left to the daunting task of adapting. In Texas, it is critical to ask whether the protocols in place at the time of the storm were good enough. This week is not the first time that children have died in a flash flood along the Guadalupe River, and reports suggest county officials struggled to raise money and then declined to install a warning system in 2018 in order to save approximately $1 million. But the country faces a larger and more daunting challenge, because this disaster โ€” like the firestorms in Los Angeles and the hurricanes repeatedly pummeling Florida and the southeast โ€” once again raises the question of where people can continue to safely live. It might be that in an era of what researchers are calling โ€œmega rainโ€ events, a flood plain should now be off-limits.

July 13, 2025

After the thirtieth consecutive month without rain, the townsfolk of San Francisco de Conchos in the northern Mexican state of Chihuahua gather to plead for divine intervention. On the shores of Lake Toronto, the reservoir behind the state’s most important dam โ€“ called La Boquilla, a priest leads local farmers on horseback and their families in prayer, the stony ground beneath their feet once part of the lakebed before the waters receded to today’s critically low levels…

“We’re currently at 26.52 metres below the high-water mark, less than 14% of its capacity.” — Rafael Betance, who has voluntarily monitored La Boquilla for the state water authority for 35 years

Now, a long-running dispute with Texas over the scarce resource is threatening to turn ugly. Under the terms of a 1944 water-sharing agreement, Mexico must send 430 million cubic metres of water per year from the Rio Grande to the US. The water is sent via a system of tributary channels into shared dams owned and operated by the International Boundary and Water Commission (IBWC), which oversees and regulates water-sharing between the two neighbours. In return, the US sends its own much larger allocation (nearly 1.85 billion cubic metres a year) from the Colorado River to supply the Mexican border cities of Tijuana and Mexicali. Mexico is in arrears and has failed to keep up with its water deliveries for much of the 21st Century…

Many in northern Mexico believe the 1944 water-sharing treaty is no longer fit for purpose. Mr Ramirez thinks it may have been adequate for conditions eight decades ago, but it has failed to adapt with the times or properly account for population growth or the ravages of climate change.

Global #drought impacts detailed in new report by National Drought Mitigation Center and UN Convention to Combat Desertification

July 2, 2025

The National Drought Mitigation Center at the University of Nebraskaโ€“Lincoln and the UN Convention to Combat Desertification have released a report outlining the impacts of drought around the world since 2023.

The report was released Wednesday, July 2, at the 4th International Conference on Financing for Development (FfD4) in Seville, Spain. 

The last two years represent some of the worst drought effects seen on a global scale, said Mark Svoboda, report co-author and NDMC director.ย 

โ€œThis is simply not just another dry spell,” he said. “This is a global catastrophe covering millions of square miles and affecting millions of people, among the worst I’ve ever seen. This report underscores the need for systematic monitoring of how drought affects lives, livelihoods and the health of the ecosystems that we all depend on.โ€  

The report covers food, water, energy crises and human tragedies that have occurred as a result of drought events in dozens of countries across the world. It shares impacts within the most acute drought hotspots in Africa, the Mediterranean, Latin America and Southeast Asia based on over 250 studies, data sources and news reports.  

โ€œThe Mediterranean countries represent canaries in the coal mine for all modern economies,โ€ Svoboda said. โ€œThe struggles experienced by Spain, Morocco and Turkey and many others to secure water, food and energy under persistent drought offer a preview of water futures under unchecked global warming. No country, regardless of wealth or capacity, can afford to be complacent.โ€  

El Niรฑo triggered dry conditions across agricultural lands, ecosystems and urban areas in 2023โ€“2024, compounding effects in regions already suffering from heat, population pressures and fragile infrastructure, said report co-author Kelly Helm Smith, NDMC assistant director and drought impacts researcher.

Drought impacts disproportionately affect vulnerable populations, including women, children, the elderly, those with chronic illness, subsistence farmers and agropastoralists, Smith said. Health risks include cholera outbreaks, acute malnutrition, dehydration and exposure to polluted water. People may also be forced to leave their homes and communities in search of work.   

Coping mechanisms for drought events grew โ€œincreasingly desperate,โ€ said Paula Guastello, lead author and NDMC drought impacts researcher. โ€œGirls pulled from school and forced into marriage, hospitals going dark, and families digging holes in dry riverbeds just to find contaminated water โ€” these are signs of severe crisis.โ€  

To provide one example from the report, forced child marriages more than doubled in the regions of Ethiopia that were hardest hit by drought during this time. Despite being an outlawed practice in the country, child marriage can provide families with income in the form of a dowry while lessening the financial burden of providing food and other necessities to the child.  

The report underscores the importance of protecting the most vulnerable people and ecosystems, Guastello said.   

“As droughts intensify, it is critical that we work together on a global scale to protect the most vulnerable people and ecosystems and re-evaluate whether our current water use practices are sustainable in today’s changing world,โ€ she said.  

Future suffering and devastation could be reduced by acting now, Smith said.   

โ€œDrought is not just a weather event โ€“ it can be a social, economic, and environmental emergency,โ€ Smith said. โ€œThe question is not whether this will happen again, but whether we will be better prepared next time.โ€  

Guastello emphasized the need to invest in water-efficient infrastructure and nature-based solutions, equitably distributing resources to those affected by drought, and implementing policy changes regarding water use and human rights โ€” particularly of women, girls, and Indigenous tribes.

It is crucial to act now to reduce effects of future droughts, Smith said, by working to improve access to food, water, education, health care and economic opportunity, especially for the most vulnerable people.  

Enhancing support for the Sustainable Development Goals, a focus of the Seville meeting, would help reduce the effects of future droughts, she added. 

โ€œThe nations of the world have the resources and the knowledge to prevent a lot of suffering,โ€ she said. โ€œThe question is, do we have the will?โ€

U.S. rocked by four 1-in-1,000-year storms in less than a week: #ClimateChange is making severe storms both more common and more intense — NBC News

Click the link to read the article on the NBC News website (Denise Chow). Here’s an excerpt:

July 10, 2025

First the river rose in Texas. Then, the rains fell hard over North Carolina, New Mexico and Illinois. In less than a week, there were at least four 1-in-1,000-year rainfall events across the United States โ€” intense deluges that are thought to have roughly a 0.1% chance of happening in any given year…At least 120 people were killedย across six counties in central Texasโ€™ Hill Country region last week, afterย heavy rain caused catastrophic flash flooding. The Guadalupe River, near Kerrville, surged more than 20 feet in 90 minutes during the storm, washing away roads and causing widespread devastation. Days later, on Sunday, Tropical Storm Chantal drenched parts of North Carolina. Extensive flooding was reported across the central portion of the state, with some areas receiving nearly 12 inches of rain in only 24 hours. Local officials are still confirming the total number of deaths from the flooding, all while the region is under another flood watch Thursday. In New Mexico on Tuesday, at leastย three people were killed by devastating flash floodsย that swept through the remote mountain village of Ruidoso, about 180 miles south of Albuquerque. Andย in Chicago that same day, 5 inches of rain fell in only 90 minutes over Garfield Park, prompting multiple rescues on the west side of the city.

โ€œThe probability is 0.1% for your location each year, so itโ€™s very unlikely to occur where you are, but over an entire country, some of them are going to happen somewhere each year,โ€ said Russ Schumacher, director of the Colorado Climate Center at Colorado State University and the state climatologist…

Itโ€™s often tricky to untangle the precise influence that climate change had on individual weather events, but scientists agree that severe storms are more likely in a warming world โ€” along with more intense rainfall.

โ€œThis is one of the areas where attribution science is more solid, because the underlying physics is relatively simple,โ€ Schumacher said.

A warmer atmosphere can hold more water, making storms capable of dumping huge amounts of rain over land. Studies have shown that for every degree Fahrenheit that the planet heats up, the atmosphere can hold around 3% to 4% more moisture.

Weak monsoons could ‘ramp up,’ #drought remains — The #PagosaSprings Sun #SanJuanRiver #ColoradoRiver #COriver #aridification

July 9, 2025

Pagosa Country could see above-normal temperatures and above-normal precipitation in mid-July, according to the National Weather Service (NWS) Climate Prediction Centerโ€™s outlook for July 14-18.

That aligns with Pagosa Weatherโ€™s July 8 forecast that suggests, โ€œWeak monsoon activity will ramp up next week,โ€ though the organization notes later in its forecast, โ€œThe 8-14 day periodโ€ฆ Weak monsoon activity will ramp up. Weโ€™ll see more showers and thunderstorms most afternoons, but I donโ€™t see any big soakings on the horizon.โ€

Drought

According to the U.S. Drought Monitor, all of Archuleta County continued to be in drought as of July 1 โ€” the most recent drought map available. The northwest portion of the county is listed as being in moderate drought, most of the county in severe drought and 10.64 percent of the eastern portion of the county in extreme drought…

River conditions

The San Juan River in Pagosa Springs was running at 41.9 cubic feet per second (cfs) as of noon on Wednesday, July 9, according to the U.S. Geological Survey (USGS). The July 9 median streamflow for July 9 is 255 cfs, according to the USGS, with the mean flow for the same date being 447 cfs. According to 89 years of data, the lowest river flow on July 9 came in 2002, when the riverโ€™s streamflow was at 16.4 cfs. The highest streamflow for that date came in 1995, when the river was at 2,290 cfs. Pagosa Weatherโ€™s Shawn Prochazka notes the current river conditions can be fatal for fish.

โ›ˆ๏ธ Wacky Weather Watchโšก๏ธ

Earlier this week I was gazing with some amount of wonder at the Watch Duty fire map. Wildfires were cropping up in nearly every corner of the West, from the slopes of Navajo Mountain to the forests southwest of Window Rock; from the Gila Wilderness to two large blazes in southwestern Utah; from the Madre Fire north of Santa Barbara to the Gothic Fire in Nevada.

Oddly, however, Colorado seemed to be dodging fire season, despite ongoing drought conditions. That all changed a couple of days later, as blazes were sparked โ€” mostly by lightning, it seems โ€” along both rims of the Black Canyon of the Gunnison, on the Uncompahgre Plateau, and outside Buena Vista. Meanwhile, the Deer Creek Fire raced through 4,000 acres of forest and brush on the slopes of the La Sal Mountains just over the Utah border in just a matter of hours.

This isnโ€™t surprising. Even in a not-so-dry year one would expect to see smoke in the air in July, especially when hotter than normal temperatures (Arches National Park recorded 106ยฐ F on July 10) combine with afternoon thunderstorms that bring a lot of lightning but not much rainfall.

But it does seem a little bit odd to be worrying about wildfires when, not far away, people and houses are literally being carried away by floodwaters. First came the horrible and heartbreaking tragedy in Texasโ€™ Hill Country. Then, just a day or two later, more than three inches of rain fell over a couple of hours on the South Fork wildfire burn scar in southern New Mexico, sending mud-and-debris filled flash floods careening through the community of Ruidoso, killing three and damaging hundreds of houses and infrastructure.


The 1911 Flood: Could it happen again? — Jonathan P. Thompson


Ruidoso canโ€™t seem to catch a break from climate change-exacerbated disasters. In April 2022, theย McBride Fireย ripped through the area, killing two people and destroying more than 200 homes. Then, last June, theย South Fork and Salt Firestogether burned nearly 25,000 acres and some 1,400 structures. Shortly thereafter heavy rains on the burn scar led to major flash flooding in the town.

This time there was even more rain in a shorter period of time, sending a massive wall of water down the Rio Ruidoso. In less than an hour, the riverโ€™s flow jumped from about 7 cubic feet of water per second, to 5,200 cfs (with the gage height leaping from 1.45 feet to 18.42 feet). Thatโ€™s the highest flow by far since records began in 1958, and 700 cfs higher than last yearโ€™s post-fire flood. It turned the creek into aย destruction machine.

Since record keeping began in 1954, the Rio Ruidoso did not even get close to 3,000 cfs until 2008. Since then it has exceeded that level four times, setting new records in both 2024 and 2025, which is likely because of increased runoff from the South Fork fire burn scar. Source: USGS.

Climate scientists have concluded that climate heating most likely intensified the Texas storms, finding, โ€œNatural variability alone cannot explain the changes in precipitation associated with this very exceptional meteorological condition.โ€ And it certainly safe to say that the severity of both the New Mexico and Texas storms fit the pattern that one would expect to see as the climate heats up. Warmer air carries more moisture and has more energy, meaning it can lead to more acute storms.

But folks of a certain political bent think something else entirely is to blame: Deep-state โ€œweather weaponsโ€ and cloudseeding. And they are serious enough about it that they are vandalizing weather radars and threatening to kill folks who work in the weather modification field. This WIRED article gives a good overview of the conspiracy theories at work.

Itโ€™s obviously a crock of cuckoo, for so many reasons. Deep state? Weather weapon? Targeting both red Texas and deep blue New Mexico? Yeah, no. Letโ€™s say you do buy into all of that, then you might want to consider the questionable efficacy of said weather weapon.

Cloud-seeding graphic via Science Matters

Western water managers and ski areas have been trying to wring more snow from storms via cloudseeding for decades. Maybe, just maybe theyโ€™ve been able to increase precipitation from select storms by a as much as 10%, although thatโ€™s difficult to ascertain. And yet, they have not been able to end the megadrought that has seized the Southwest for two-and-a-half decades, they have not been able to concoct enough storms to fill Lakes Powell and Mead, and they have not delivered endless powder days to Rocky Mountain ski resorts.

Anyway, this is just an excuse to link to this old video on Project Skywater, which was the Bureau of Reclamationโ€™s 1970s effort to use cloudseeding to increase snowpack in the Colorado River Basin to meet growing demands for water. It was a big, well-funded project. It didnโ€™t yield much in the way of results. Nevertheless, it was the impetus for the San Juan Avalanche Project, which brought a herd of snow experts to Silverton to do a comprehensive study of avalanches and the potential impacts all of that new cloudseeding-yielded snow would bring.

Sorry for the poor production quality of the video, but itโ€™s almost as old as I am, so what do you expect? Besides, itโ€™s got a cool soundtrack.

๐Ÿคฏ Crazytown Chronicle ๐Ÿคก

Itโ€™s funny, back in 1971, the Interior Department (via its Bureau of Rec) was putting out informative videos about attempted weather modification. Now they are spewing MAGA-cult propaganda that shouts Kim Jong Un. Oh how our public lands overseer has fallen! It refers to Trump as the โ€œmost iconicโ€ president ever. Whatever the frack that means. Oh, also, expect an โ€œiconicโ€ fireworks show over Mt. Rushmore next year.

๐Ÿ“ˆ Data Dump ๐Ÿ“Š

After pondering population growth and development in Kanab, Utah, in the last dispatch, I figured Iโ€™d take a look at where in the West folks are moving to in the post-COVID era. The answer: Arizona. Specifically Pinal County, which had the highest net in-migration rate1 from 2023 to 2024, and Maricopa County, which had the largest number of net in-migrants. San Juan County, Colorado, is also in the top 20 for migration rates, but that wasnโ€™t exactly due to a massive population influx to the mountain town. It had a net in-migration of just 20 people, which is a lot in a county of 800 people.


As the Colorado River shrinks, desert towns grow Jonathan P. Thompson


Keep in mind this is not the population growth rate, which includes births and deaths, but just the migration rates (though the two closely correspond). 

Many of these counties are the usual suspects, but there are some surprises. San Miguel (Telluride), Eagle (Vail), Hinsdale (Lake City), and Dolores (Rico) counties, all in Colorado, have some of the highest rates of out-migration in the West. These same counties had relatively high net in-migration between 2021 and 2023. The cause of the exodus is not clear, though it might have to do with high housing prices, which plague all of these places. 

Pinal Countyโ€™s appeal is probably related to it becoming an electric vehicle, battery, and other high-tech manufacturing hub in recent years, boosted by Biden-era incentives. Congress and Trump killed many of those incentives with their recent budget reconciliation bill, possibly jeopardizing at least some of the new firms and jobs. It will be interesting to see if the 2024 migration trends can continue. Neighboring Maricopa County continues to draw tens of thousands of new residents and air-conditioning-dependents each year, never mind that the mercury hit 118ยฐ F a couple of days ago. 

And now, on to the charts.

Increased sampling efforts result in additional zebra mussel detections in Western #Colorado — Colorado Parks & Wildlife #ColoradoRiver #COriver

Click the link to read the release on the Colorado Parks & Wildlife website (Rachael Gonzales):

On Thursday, July 3, Colorado Parks and Wildlife (CPW) Aquatic Nuisance Species (ANS) staff discovered a large number of adult zebra mussels in a privately owned body of water in western Eagle County. 

โ€œThis news is a direct result of increased sampling efforts, โ€ said CPW Director Jeff Davis. โ€œThis discovery is a significant step toward identifying a potential source of zebra mussels and advancing our efforts for eradication. It would not have been possible without the commitment to protect Coloradoโ€™s bodies of water by our Aquatic Nuisance Species staff.โ€

During the survey, staff discovered evidence of and collected samples of suspected adult zebra mussels in various locations. Visual identification of the samples was performed by ANS Staff and samples were sent to Aquatic Animal Health Lab (AAHL) for DNA confirmation. 

CPW staff is currently evaluating options for the next steps in eradicating zebra mussels from the body of water.

โ€œUnderstanding the current extent of zebra mussels in western Colorado is a critical step in stopping their spread into new locations,โ€ said CPW Invasive Species Program Manager Robert Walters. โ€œEvery new detection puts us one step closer to achieving this desired outcome.โ€ 

CPW, in collaboration with our partners at the local, state and federal levels, will continue our increased sampling and monitoring efforts. We also appreciate the willingness of private businesses and individuals who allow our staff to access their properties to conduct surveys.

In addition to the discovery found in western Eagle County, CPW also identified additional zebra mussel veligers in the Colorado River near New Castle, Highline Lake and Mack Mesa Lake at Highline Lake State Park.

Colorado River
On July 3, CPW Aquatic Animal Health Lab (AAHL) confirmed three additional zebra mussel veligers in samples collected in the Colorado River between Glenwood Springs and Silt. Samples were collected on June 16 and taken to the ANS laboratory where the additional zebra mussels veligers were found. These samples were then sent to AAHL for DNA confirmation.

With the additional detections in sample results, the Colorado River is now considered “positiveโ€ for zebra mussels from the confluence of the Roaring Fork River to the Colorado-Utah border.

Since sampling efforts resumed in May, CPW has collected 225 water samples from various locations along the Colorado River, stretching from the headwaters in Grand County to the Colorado-Utah border. In addition to the samples from the Colorado River, ANS staff has collected 25 samples from the Eagle River and nine samples from the Roaring Fork River. There have been no detections of zebra mussel veligers in the samples from the Eagle and Roaring Fork rivers. To date, no adult zebra mussels have been detected in the Colorado, Eagle or Roaring Fork rivers. 

Highline Lake
On June 10, CPW ANS staff collected plankton samples from the patrol dock and inlet at Highline Lake as part of routine increased sampling efforts. ANS laboratory technicians identified one suspected zebra mussel veliger in each sample. The samples were sent to AAHL where they were genetically confirmed as zebra mussels.

โ€œWhile we had maintained hope that our eradication efforts at Highline Lake would be successful, we have always known this was a lofty goal. This is the primary reason we have continued the implementation of the containment watercraft inspection and decontamination program at Highline Lake,โ€ said Walters.

With Highlineโ€™s current designation as an infested body of water, boaters are reminded of the following protocols in place since 2023.

  • Boats launchingโ€‹ at Highline Lake will be subject to inspection and decontamination protocols before launching.ย 
  • All boats must be clean, drained and dry before launching at Highline Lake, or they will be decontaminated.
  • Upon exiting the lake, all boats will be inspected and decontaminated, and boaters will be issued a green seal and a blue receiptโ€‹ indicating the boat was last used on a body of water with a known aquatic nuisance species.ย 

Mack Mesa
On June 10, CPW ANS staff collected plankton samples in the area near the fishing pier at Mack Mesa Lake, located at Highline Lake State Park. ANS laboratory technicians identified one suspected zebra mussel veliger in the sample. The samples were sent to AAHL where the zebra mussel veliger was genetically confirmed.

On July 8, additional samples collected from Mack Mesa indicated additional zebra mussel veligers. With these additional detections, Mack Mesa is now considered “positiveโ€ for zebra mussels.

CPW is continuing to evaluate options for the future management of Highline Lake and Mack Mesa based on the latest sampling results.

Prevent the spread: Be a Pain in the ANS
Everyone has a part to play in preventing the introduction and spread of invasive species in Colorado. Simple actions like cleaning, draining and drying your motorized and hand-launched vessels โ€” including paddleboards and kayaks โ€” and angling gear after you leave the water can make a big difference to protect Colorado’s waters.

Learn more about how you can prevent the spread of aquatic nuisance species and tips to properly clean, drain and dry your boating and fishing gear by visiting our website. Tips for anglers and a map of CPWโ€™s new gear and watercraft cleaning stations are available here.

CPW also encourages those who use water pulled from the Colorado River and find any evidence of mussels or clams to send photos to Invasive.Species@state.co.us for identification. It is extremely important to accurately report the location in these reports for follow-up surveying.

In the Sweltering Southwest, Planting Solar Panels in Farmland Can Help Both Photovoltaics and Crops — Tina Deines (InsideClimateNews.com)

July 10, 2025

Agrivoltaic solar arrays can shade crops from sun while moisture from vegetation cools the panels to increase their productivity, researchers and farmers have found.

โ€œWe were getting basil leaves the size of your palm,โ€ University of Arizona researcher Greg Barron-Gafford said, describing some of the benefits he and his team have seen farming under solar panels in the Tucson desert.

For 12 years, Barron-Gafford has been investigating agrivoltaics, the integration of solar arrays into working farmland. This practice involves growing crops or other vegetation, such as pollinator-friendly plants, under solar panels, and sometimes grazing livestock in this greenery. Though a relatively new concept, at least 604 agrivoltaic sites have popped up across the United States, according to OpenEI

Researchers like Barron-Gafford think that, in addition to generating carbon-free electricity, agrivoltaics could offer a ray of hope for agriculture in an increasingly hotter and drier Southwest, as the shade created by these systems has been found to decrease irrigation needs and eliminate heat stress on crops. Plus, the cooling effects of growing plants under solar arrays can actually make the panels work better.

But challenges remain, including some farmersโ€™ attitudes about the practice and funding difficulties. 

Overcoming a Climate Conundrum

While renewable electricity from sources like solar panels is one of the most frequently touted energy solutions to help reduce the carbon pollution thatโ€™s driving climate change, the warming climate itself is making it harder for solar arrays to do their job, Barron-Gafford said. An optimal functioning temperature for panels is around 75 degrees Fahrenheit, he explained. Beyond that, any temperature increase reduces the photovoltaic cellsโ€™ efficiency. 

โ€œYou can quickly see how this solution for our changing climate of switching to more renewable energy is itself sensitive to the changing climate,โ€ he said.

This problem is especially pertinent in the Southwest, where historically hot temperatures are steadily increasing. Tucson, for instance, saw a record-breaking 112 days of triple-digit heat in 2024, according to National Weather Service Data, and the U.S. Environmental Protection Agencyreports that every part of the Southwest experienced higher average temperatures between 2000 and 2023 compared to the long-term average from 1895 to 2023.

However, planting vegetation under solar panelsโ€”as opposed to the more traditional method of siting solar arrays on somewhat barren landโ€”can help cool them. In one set of experiments, Barron-Gaffordโ€™s team found that planting cilantro, tomatoes and peppers under solar arrays reduced the panelsโ€™ surface temperature by around 18 degrees Fahrenheit. Thatโ€™s because plants release moisture into the air during their respiration process, in which they exchange oxygen for carbon dioxide. 

โ€œThis invisible power of water coming out of plants was actually cooling down the solar panels,โ€ Barron-Gafford said.

Throwing Shade

While Barron-Gafford said some laughed him off when he first proposed the idea of growing crops in the shade of solar panels, this added sun shield can actually help them grow better, especially in the Southwest, where many backyard gardeners already employ shade cloths to protect their gardens from the blazing heat. 

โ€œMany people donโ€™t understand that in Colorado and much of the West, most plants get far too much sunlight,โ€ said Byron Kominek, owner/manager of Jackโ€™s Solar Garden in Boulder County, Colorado, which began implementing agrivoltaics in 2020. โ€œHaving some shade is a benefit to them.โ€

Jackโ€™s Solar Garden has integrated 3,276 solar panels over about four acres of farmland, growing crops like greens and tomatoes. Meg Caley with Sprout City Farms, a nonprofit that helps with farming duties at Jackโ€™s Solar Garden, said theyโ€™ve been able to produce Swiss chard โ€œthe size of your torso.โ€

โ€œThe greens just get huge,โ€ she said. โ€œYou have to chop them up to fit them in your refrigerator.โ€

She added that the shade seems to improve the flavor of the vegetables and prevents them from bolting, when plants prematurely produce flowers and seeds, diverting energy away from leaf or root growth.

โ€œPlants when theyโ€™re stressed out can have more of a bitter flavor,โ€ she explained. โ€œSo the arugula that we grow is not as bitter or spicy. Itโ€™s sweeter. The spinach is sweeter too.โ€

Barron-Gafford and his team are seeing the same thing in Arizona, where they grow a variety of produce like beans, artichokes, potatoes, kale and basil.

โ€œWeโ€™ve grown 30-plus different types of things across different wet winters and dry winters and exceptionally hot summers, dry summers, average or close to average summers,โ€ he said of the solar-shaded crops. โ€œAnd across everything weโ€™ve done, weโ€™ve seen equal or greater production down here in the Southwest, the dry land environments, where it really benefits to get some shade.โ€

As in Colorado, some of those crops are growing to epic proportions. 

โ€œWeโ€™ve made bok choy the size of a toddler,โ€ Barron-Gafford said.

All that shade provides another important benefit in a drought-stricken Southwestโ€”lower water requirements for crops. Because less direct sunlight is hitting the ground, it decreases the evaporation rate, which means water stays in the soil longer after irrigation. Barron-Gafford and his team have been running experiments for the last seven or so years to see how this plays out with different crops in an agrivoltaic setting. 

โ€œWhat is the evaporation rate under something thatโ€™s big and bushy like a bean or potato plant versus something thinner above ground, like a carrot?โ€ is one of the questions Barron-Gafford said they have tried to answer. โ€œFor the most part, I would say that we are able to cut back our irrigation by more than half.โ€

They are partnering with Jackโ€™s Solar Farm on water research in Colorado and have so far found similar results there. 

This shade has another benefit in a warming worldโ€”respite for farmworkers. Heat-related illnesses are a growing concern for people who work outside, and one recent study predicted climate change will quadruple U.S. outdoor workersโ€™ exposure to extreme heat conditions by 2065.

But with solar arrays in the fields, โ€œif you really carefully plan out your day, you can work in the shade,โ€ a factor that can help increase worker safety on hot days, Caley said.

The AgriSolar Clearinghouse performed skin temperature readings under solar panels and full sun at a number of sites across the United States, finding a skin temperature decrease of 15.3 degrees in Boulder and 20.8 degrees in Phoenix.

โ€œI Donโ€™t Know What the Future Holdsโ€

Despite the benefits of agrivoltaics, the up-front cost of purchasing a solar array remains a barrier to farmers. 

โ€œOnce people see the potential of agrivoltaics, you run into the next challenge, which is how do you fund someone getting into this on their site?โ€ Barron-Gafford said. โ€œAnd depending on the amount of capital or access to capital that a farmer has, youโ€™re going to get a wildly different answer.โ€

While expenses are dependent on the size of the installation, a 25 kilowatt system would require an upfront cost of around $67,750, according toAgriSolar Clearinghouse. For comparison, the median size of a residential solar array in 2018 was around 6kW, the organization stated, which would cost around $16,260 to install.

Kominek said the total initial cost of implementing a 1.2 megawatt capacity agrivoltaics setup on his farm in Colorado was around $2 million, but that the investment has paid off. In addition to the revenue he earns from farming, all of the energy produced by the arrays is sold to clients in the community through a local utility company, earning the farm money.

The Rural Energy for America program has been one resource for farmers interested in agrivoltaics, offering loans and grants to help install solar. However, itโ€™s unclear how this program will move forward amid current federal spending cuts.

Meanwhile, some of the federal grant programs that Barron-Gafford has relied on have suddenly come to a halt, he said, putting his research in danger. But, as federal support dries up, some states are charging on with their own funding opportunities to develop farm field solar projects. For instance, Coloradoโ€™s Agrivoltaics Research and Demonstration Grant offers money for demonstrations of agrivoltaics, research projects and outreach campaigns.

There are other challenges as well. Caley, for instance, said farming around solar panels is akin to working in an โ€œobstacle course.โ€ She and her team, who mostly work manually, have found ways to work around them by being aware of their surroundings so that they donโ€™t accidentally collide with the panels or strike them with their tools. This job is also made easier since Kominek invested between $80,000 and $100,000 to elevate his farmโ€™s panels, which better allows animals, taller crops and farming equipment to operate beneath.

Still, a 2025 University of Arizona study that interviewed farmers and government officials in Pinal County, Arizona, found that a number of them questioned agrivoltaicsโ€™ compatibility with large-scale agriculture.

โ€œI think itโ€™s a great idea, but the only thing โ€ฆ it wouldnโ€™t be cost-efficient โ€ฆ everything now with labor and cost of everything, fuel, tractors, it almost has to be super big โ€ฆ to do as much with as least amount of people as possible,โ€ one farmer stated.

Many farmers are also leery of solar, worrying that agrivoltaics could take working farmland out of use, affect their current operations or deteriorate soils.

Those fears have been amplified by larger utility-scale initiatives, like Ohioโ€™s planned Oak Run Solar Project, an 800 megawatt project that will include 300 megawatts of battery storage, 4,000 acres of crops and 1,000 grazing sheep in what will be the countryโ€™s largest agrivoltaics endeavor to date. Opponents of the project worry about its visual impacts and the potential loss of farmland.

The latest El Niรฑo/Southern Oscillation (#Enso) Diagnostic Discussion is hot off the presses from the #Climate Prediction Center

July 10, 2025

ENSO Alert System Status: Not Active

Synopsis: ENSO-neutral is most likely through the late Northern Hemisphere summer

2025 (56% chance in August-October). Thereafter, chances of La Niรฑa conditions increase into the fall and winter 2025-26, but remain comparable to ENSO-neutral.

During June 2025, ENSO-neutral continued, with near-average sea surface temperatures (SSTs) prevailing across most of the equatorial Pacific Ocean. The latest weekly Niรฑo SST index values ranged from 0.ยฐC to +0.4ยฐC. Subsurface temperature anomalies were weakly positive and nearly unchanged from last month, with mostly above-average temperatures established along the thermocline. Over the east-central and eastern equatorial Pacific Ocean, low-level wind anomalies were easterly and upper-level wind anomalies were westerly. Convection remained enhanced over Indonesia. Collectively, the coupled ocean-atmosphere system in the tropical Pacific reflected ENSO-neutral.

The IRI predictions indicate ENSO-neutral is most likely through the Northern Hemisphere winter 2025-26. In contrast, the North American Multi-Model Ensemble favors the onset of La Niรฑa conditions during the Northern Hemisphere fall, though lasting a shorter duration than NOAAโ€™s requirement of five consecutive overlapping 3-month seasons. While the subsurface equatorial Pacific remains above average, easterly trade winds are predicted to strengthen in the coming month, which could portend cooler conditions. In summary, ENSO-neutral is most likely through the late Northern Hemisphere summer 2025 (56% chance in August-October). Thereafter, chances of La Niรฑa conditions increase into the fall and winter 2025-26, but remain nearly equal to ENSO-neutral.

$4 million in federal funds restored for Upper #ColoradoRiver Basin watersheds damaged by fire, overgrazing — Jerd Smith (Fresh Water News) #COriver #aridification

July 10, 2025

Millions of dollars in federal funding has been released to continue restoring lands and streams in the fire-scarred Upper Colorado River Basin watershed in and around Grand Lake and Rocky Mountain National Park.

The roughly $4 million was frozen in February and released in April, according to Northern Water, a major Colorado water provider and one of the agencies that coordinates with the federal government and agencies such as the U.S. Forest Service to conduct the work. 

Esther Vincent, Northern Waterโ€™s director of environmental services, said the federal government gave no reason for the freeze and release of funds.

The amounts and timing of the freeze and release are being reported here for the first time.

U.S. Congressman Joe Neguse, who represents Grand County, did not respond to a request for comment regarding the funds.

The news comes as tens of millions of dollars in federal grants and budget allocations are being cut in Colorado and across the country as part of the Trump administrationโ€™s reorganization of federal agencies and associated budget cuts.

In June, Gov. Jared Polisโ€™ office released an accounting of federal money that has flowed to state agencies. That analysis showed the agencies were able to retain $282 million in funding, but that $76 million had been lost, and another $56 million is at risk.

Itโ€™s unclear how much funding that flows through federal agencies to other Colorado entities and nonprofits such as those in the Upper Colorado River Basin, has been lost.

The U.S. Forest Service did not respond to a request for comment. The U.S. Bureau of Reclamation declined to comment on the funding actions.

In Grand County, $761,000 has been released from the U.S. Bureau of Reclamation to help move forward on a broad-based effort by the Kawuneeche Valley Restoration Collaborative, according to Northern Water. The valley has been damaged by drought, failing irrigation systems and overgrazing by wildlife and is a critical piece of the Colorado Riverโ€™s upper watershed. The collaborative, established in 2020, is a major partnership of seven entities, including Northern Water, Grand County, the Nature Conservancy and Rocky Mountain National Park.

The $3.3 million in East Troublesome fire funding that has been released through the U.S. Forest Service will help restore the watershed around Grand Lake and land in Rocky Mountain National Park. The fire began in October 2020 and burned nearly 200,000 acres, making it the second largest fire in Colorado history.

The fire burned land that constitutes a sprawling water collection area for Northern Water, a major water provider that pipes Colorado River water from Grand County, under the Continental Divide and east to the Front Range, where it serves roughly 1 million residents of northern Colorado and hundreds of farms.

Steve Kudron, former mayor of Grand Lake who now serves as its town manager, said restoration work in both projects is critical to the economy and health of the historic tourist town, which lies at the western edge of Rocky Mountain National Park.

โ€œThe biggest concerns that we had were closing parts of the forest because there hasnโ€™t been sufficient cleanup. Some mountainsides are unstable,โ€ he said. โ€œItโ€™s the funding that makes it safe for the public to go into those areas. Thatโ€™s why it was important to get the funding back.โ€

May 19, 2025

In summer 2021, 90% of the western United States (WUS) experienced drought, with over half of the region facing extreme or exceptional conditions, leading to water scarcity, crop loss, ecological degradation, and significant socio-economic consequences. Beyond the established influence of oceanic forcing and internal atmospheric variability, this study highlights the importance of land-surface conditions in the development of the 2020โ€“2021 WUS drought, using observational data analysis and novel numerical simulations. Our results demonstrate that the soil moisture state preceding a meteorological drought, due to its intrinsic memory, is a critical factor in the development of soil droughts. Specifically, wet soil conditions can delay the transition from meteorological to soil droughts by several months or even nullify the effects of La Niรฑa-driven meteorological droughts, while drier conditions can exacerbate these impacts, leading to more severe soil droughts. For the same reason, soil droughts can persist well beyond the end of meteorological droughts. Our numerical experiments suggest a relatively weak soil moisture-precipitation coupling during this drought period, corroborating the primary contributions of the ocean and atmosphere to this meteorological drought. Additionally, drought-induced vegetation losses can mitigate soil droughts by reducing evapotranspiration and slowing the depletion of soil moisture. This study highlights the importance of soil moisture and vegetation conditions in seasonal-to-interannual drought predictions. Findings from this study have implications for regions like the WUS, which are experiencing anthropogenically-driven soil aridification and vegetation greening, suggesting that future soil droughts in these areas may develop more rapidly, become more severe, and persist longer.

Key Points

  • Initial soil moisture conditions strongly impacted the meteorological to soil drought transition in the western United States in 2020โ€“2021
  • Drought-induced vegetation feedbacks can influence the evolution of soil droughts in the western United States
  • Future soil droughts in the western United States are likely to become more severe, develop more rapidly, and persist longer

Plain Language Summary

In summer 2021, nearly all the western United States (WUS) experienced drought, leading to water shortages and agricultural losses. While previous studies have predominantly focused on oceanic and atmospheric drivers of droughts in the WUS, our study explores how land-surface conditions contributed to the evolution of this real-world drought. We find that the initial moisture level in the soil is crucial for the transition of precipitation deficits into more impactful soil droughts. Moist soils can delay the onset of soil droughts when precipitation is lacking, whereas drier soils can quickly result in more severe and long-lasting soil droughts. Low soil moisture levels can maintain soil droughts for several months, even after meteorological conditions improve. The vegetation degradation during droughts can lessen the rate of soil drying by reducing the amount of moisture that plants transfer to the atmosphere, which may help reduce the severity of soil droughts. Our findings emphasize the importance of accounting for land-surface conditions, such as soil moisture and vegetation conditions, in seasonal-to-interannual drought predictions. Moreover, our work suggests that as the WUS becomes drier and vegetation condition change due to climate change, future soil droughts in the region might become more severe, develop faster, and persist longer.

#RioGrande Compact settlement is โ€˜on track…this is an extraordinary moment unlike any in history’ — Colorado State Attorney General Phil Weiser (AlamosaCitizen.com)

Click the link to read the article and listen to the Valley Pod on the Alamosa Citizen website:

July 9, 2025

A draft agreement settling the long-running Rio Grande Compact lawsuit dealing with New Mexicoโ€™s delivery of water to the Texas border is on the one-yard line and should be pushed across the goal line come fall, says Colorado Attorney General Phil Weiser.

Weiser was on a two-day tour of the San Luis Valley this week when he gave an update on the lawsuit to members of the Rio Grande Basin Roundtable. All three compact states โ€“ Colorado, New Mexico and Texas will be party to the settlement. 

Earlier this week, Special Master D. Brooks Smith scheduled a hearing for the week of Sept. 29 on the parties motions toward a settlement. 

The states had worked out a previous agreement to the 2013 case, only to have the federal government object when the proposed settlement was presented to the U.S. Supreme Court. This time, said Weiser, the federal governmentโ€™s role has been addressed.

โ€œWeโ€™re on track,โ€ Weiser said during a recording of The Valley Pod. โ€œWe have a settlement that properly has the federal government in its place and resolves the concerns which were mostly between New Mexico and Texas.โ€


Listen hereย to the full Valley Pod episode with AG Phil Weiser.


Colorado has nine interstate water compact agreements, including the Colorado River Compact which dominates the headlines. At the Rio Grande Basin Roundtable meeting, Conejos Water Conservancy District Manager Nathan Coombs asked Weiser how the state and local water users could collaborate on more โ€œcreative waysโ€ in administering the river compacts.

โ€œWe all agree with keeping our compacts whole. But I would ask what are some of the processes we could go through to make them more vehicles for the water users within the state as we see this drying?โ€ Coombs said.

On The Valley Pod, Weiser addressed the Valleyโ€™s efforts to recover the Upper Rio Grande Basinโ€™s confined and unconfined aquifers.

โ€œWe will have to continue looking at this situation of groundwater and have to keep asking โ€˜How do we best manage this precious resource?โ€™ I donโ€™t have any immediate views on what to do in the face of the challenging hydrology. I do believe we have to keep thinking hard about a series of strategies that include โ€˜How are we most smartly storing water, how are we re-using water, and how are we conserving water?โ€™โ€

Weiser, a two-term attorney general, is a candidate for governor, seeking the Democratic Party nomination in 2026. In The Valley Pod episode he talks more about his candidacy as well as the 27 different lawsuits Colorado has been party to in the past six months in challenging the Trump Administration.

โ€œThis is an extraordinary moment unlike any in history,โ€ Weiser said.

The July 10, 2025 briefing in hot off the presses from Western Water Assessment

Click the link to read the briefing on the Western Water Assessment website:

During June, much of the region experienced above average temperatures and below average precipitation. Record low precipitation fell across parts of northern Utah and southwestern Wyoming while much above average precipitation was observed in southern Utah and southwestern Colorado. As of July 1, seasonal snowmelt was completed with many mountain locations melting out 1-2 weeks earlier than average. Seasonal streamflow volume forecasts remained below to much below normal with the inflow to Lake Powell forecasted to be 42% of average. Regional coverage of drought expanded significantly from 53% in early June to 63% on July 1, driven largely by expansion of drought in Utah. Drought conditions are likely to persist or worsen as NOAA seasonal forecasts suggest above average regional temperatures and below average precipitation for Wyoming during July to September.

Above average June precipitation was observed in southern Utah, eastern Wyoming and the majority of Colorado. Much of Utah and Wyoming and northwestern Colorado received below average precipitation during June. Parts of southern Colorado and southern Utah received twice the average June rainfall while some locations in northern Utah and southwestern Wyoming observed record low June rainfall totals. Average June rainfall is typically low in the Intermountain West and areas of southern Utah and southwestern Colorado with 150-400% of average June rainfall observed total rainfall amounts of 1-2 inches.

June temperatures were above average for much of Colorado, Utah and Wyoming, except for eastern Colorado and Wyoming where temperatures were up to two degrees below average. The warmest temperatures were observed in Utah, northwestern Colorado, and western Wyoming where June average temperatures were in the top 10% of all observations since 1895.

As of July 1st, snowpack was melted out across the region and snowmelt occurred earlier than average across all basins except the Tongue River Basin in northern Wyoming. In Colorado, snowmelt occurred only a few days early in the Arkansas and South Platte River Basins, around a week early in the Animas, Colorado Headwaters, Dolores, Gunnison and Yampa River Basins, two weeks early in the San Juan River Basin and nearly four weeks early in the Rio Grande River Basin. In Utah, snowmelt was only a few days early in the Bear River Basin, 1-2 weeks early in the northern Utah, Price, Sevier and Virgin River Basins and 24 days early in the Escalante River Basin. In Wyoming, snowmelt occurred earlier than average in all basins except the Tongue River Basin, with the Belle Fouche, Cheyenne and Snake River Basins melting out 2-3 weeks early.

Regional drought coverage expanded from 53% in early June to 63% as of July 1 with all of Utah and about half of Colorado and Wyoming experiencing drought. Extreme (D3) drought conditions expanded in western Colorado but were removed from southwestern Utah and southeastern Wyoming where above average June precipitation was observed. Drought worsened by one to two classes in northern Utah and southwestern Wyoming, but drought conditions improved in portions of eastern and southern Colorado and southern Utah. In eastern Wyoming, drought conditions improved by one to three drought classes.

West Drought Monitor map July 8, 2025.

Seasonal streamflow volume forecasts remained below to much below average with the final forecasts of the year ranging from 33% of average for Utahโ€™s Bear and Virgin River Basins to 86% of average in Wyomingโ€™s Shoshone and Yellowstone River Basins. For nearly all regional river basins, streamflow volume forecasts significantly decreased from April 1 to June or July 1. The evolution of the Yampa River seasonal streamflow forecast exemplifies a pattern seen across the Intermountain West. After a near average winter snowpack, the April 1 forecast indicated an average seasonal streamflow volume, but by July 1, the Yampa River forecast declined to only 51% of average. Much below streamflow volume forecasts (<60% of average) were issued for the Colorado Headwaters, Dolores, San Juan and Yampa River Basins in Colorado, the Bear, Duchesne, Green, San Juan, Sevier, Virgin and Weber River Basins in Utah, and the Green, North Platte and Powder River Basins in Wyoming. The inflow forecast for Lake Powell was a paltry 42% of average on July 1.

ENSO neutral conditions currently exist in the eastern Pacific Ocean and remain most likely throughout the forecast period. The NOAA seasonal precipitation forecast for July-September suggests an increased probability of below average precipitation for Wyoming and northeastern Colorado. The seasonal temperature forecast suggests a high probability of above average temperatures for the entire region.

This Week’s Drought Summary

Drought coverage and intensity continued its decline throughout the Great Plains since the spring with additional heavy rainfall during the first week of July. Despite the extremely heavy rainfall and flash flooding this past week, long-term drought dating back multiple years remains across south-central Texas. Improving drought conditions were made to parts of New Mexico, southwestern Colorado, and Arizona, while drought expanded and intensified across the Pacific Northwest and Northern Intermountain West. Much of the Corn Belt and Midwest remains drought-free, but a continued lack of adequate precipitation led to worsening drought for northern Illinois. Following another week of summertime thunderstorms with heavy rainfall, drought ended for most of the central to southwestern Florida Peninsula. Nearly all of the East, Ohio and Tennessee Valleys, and Lower Mississippi Valley are drought-free. 7-day temperatures (July 1-7), averaged 2 to 4 degrees F above normal across the Pacific Northwest, Northern Great Plains, Midwest, and New England. Cooler-than-normal temperatures were limited to the Southern Great Plains and portions of the Southwest. Parts of northwestern Alaska and the Yukon River Valley are designated with short-term drought, while drought of varying intensity continues for Hawaii. Although Puerto Rico currently remains drought-free, short-term precipitation deficits have increased…

High Plains

Another round of heavy rainfall (1 to 2 inches, locally more) supported a 1-category improvement to parts of the Northern and Central Great Plains. April through early July is a wet time of year and 90-day precipitation, valid April 9-July 7, averaged more than 150 percent of normal for much of the Dakotas, Nebraska, eastern Colorado, and eastern Wyoming. Conversely, moderate drought (D1) across northeastern North Dakota was expanded westward due to another dry week and above-normal temperatures. The D1 is supported by the 30 to 60-day SPIs along with soil moisture indicators. Eastern Kansas has missed out on the heavy rainfall recently and abnormal dryness (D0) was added to that part of the state. Although precipitation was not that heavy across southwestern Colorado, enough precipitation along with support from SPIs at multiple time scales and the NDMC drought blends warranted small 1-category improvements…

Colorado Drought Monitor one week change map ending July 8, 2025.

West

Based on rapidly declining soil moisture and low 28-day average streamflows, additional degradations were warranted this week for the Pacific Northwest with an expanding coverage of moderate (D1) to severe (D2) drought across Oregon and Washington. Farther to the east, extreme drought (D3) was expanded to include more of northern Idaho. Parts of Utah also had a few areas with degradations based on 28-day streamflow, soil moisture, and high evaporative demand recently. A drier end to the wet season, 60 to 90-day SPI, and low soil moisture supported an expansion of abnormal dryness (D0) across northern to central California. Following recent beneficial precipitation along with timely wetness back to the late spring, improvements were warranted for parts of north-central and eastern Montana. Drought intensity remained nearly steady for the Desert Southwest although locally heavier Monsoon showers led to a small reduction in extreme drought (D3) for eastern and southern Arizona…

South

A broad one to two-category improvement was made this past week to much of the ongoing long-term drought areas of Texas along with parts of New Mexico. The heaviest precipitation (5 to 10 inches, or more) occurred across the Edwards Plateau and south-central portions of Texas. According to CoCoRaHS gauge measurements from July 1-7, precipitation amounts ranged from 12 to 18 inches in eastern Burnet and western Williamson counties of Texas. Although 1 to 2-category improvements were made, a long-term drought dating back multiple years with low groundwater and reservoir levels continue. Therefore, an area of long-term drought (D1+) was maintained. The Edwards Aquifer Authorityโ€™s long-term observation wells at Medina and Uvalde counties remain in extreme (D3) to exceptional (D4) drought levels. Elsewhere, across the Southern Great Plains and Lower Mississippi Valley, no short-term or long-term drought is designated…

Looking Ahead

From July 10 to 14, a cold front is forecast to shift southeast across the central U.S. and provide the focus for thunderstorms. The most widespread, heavy precipitation (more than 1.5 inches) is forecast across the Upper Mississippi Valley and Western Corn Belt, but locally heavy precipitation is expected as far south and west as the Southern Great Plains and eastern New Mexico. Daily convection with locally heavy precipitation is forecast across the Mid-Atlantic and Southeast, especially east of the Appalachians. A lull in the Monsoon will be accompanied by above-normal temperatures across the Desert Southwest. Dry weather and increasing heat are likely for the interior Pacific Northwest.

The Climate Prediction Centerโ€™s 6-10 day outlook (valid July 15-19, 2025) favors above-normal precipitation across the eastern two-thirds of the contiguous U.S., most of Alaska, and the western Hawaiian Islands. The largest above-normal precipitation probabilities (more than 50 percent) are forecast for the Florida Panhandle, western Texas, and eastern New Mexico. Increased below-normal precipitation probabilities are limited to the Pacific Northwest. Above-normal temperatures are favored throughout the Pacific Northwest, Great Basin, eastern Texas, Lower Mississippi Valley, and the East. Increased chances for below-normal temperatures are forecast for the Great Plains. The outlook leans cooler (warmer)-than-normal for southern (northern) Alaska.

Safeguarding the sagebrushโ€™s rich wet meadows, one #Wyoming gulch at a time: Simple erosion-control technique named after scientist Bill Zeedyk fortifies ecologically valuable riparian zones all around the western U.S — Mike Koshmrl (WyoFile.com)

Tom Christiansen drew a parallel to the human body as he described the purpose of the low-tech rock structures heโ€™s been building for years within the creases of western Wyomingโ€™s sagebrush sea. 

The malady? Erosion. The treatment: A carefully placed stone.  

โ€œEach of these is a stitch on what we donโ€™t want to become a sucking chest wound,โ€ Christiansen told a group of rock-moving volunteers on Saturday in late June. 

The group was assembled on the White Acorn Ranch, a picturesque cattle operation south of the Lander Cutoff Road thatโ€™s within the spectacular Golden Triangle โ€” a 367,000-acre region along the flanks of the Wind River Range that houses the best remaining sagebrush habitat on Earth.

The high desertโ€™s sagebrush-steppe has enormous ecological value. Thatโ€™s evidenced by the struggling species that depend upon the embattled biome. But itโ€™s an arid environment, and certain nooks and crannies play an outsized role in nourishing the landscapeโ€™s native and domesticated inhabitants. High on that list are the grassy wet meadows that convey precious water, like arteries pump blood, through the contours of the sagebrush-covered hills.

โ€œThese areas are pretty small, but theyโ€™re very important,โ€ said Christiansen, a retired sage grouse coordinator for the Wyoming Game and Fish Department. โ€œThese are the grocery stores.โ€ 

Youngsters Cooper Fieseler and Camryn Christiansen-Fieock check out a mega-sized Zeedyk structure built to address an especially broad โ€œheadcutโ€ that was eroding into the green grass uphill. (Mike Koshmrl/WyoFile)

But those bottomlands can become barren of the biomass that feeds insects, sage grouse chicks and on down the food chain. Erosion, although a natural phenomenon, can be hastened by factors like overgrazing and extreme weather events made more likely by climate change. When erosion runs out of control into grassy gulches, they become incised gullies. Out goes the vegetation. 

Thatโ€™s where the simple rock structures come in.

โ€œPrevent that erosion, get more water into the soil, keep the water table up, keep the green vegetation โ€” thatโ€™s the intent of these structures,โ€ Christiansen said. 

Known as Zeedyk structures, after their inventor, Bill Zeedyk, the stone assemblies come in different shapes and sizes. At the White Acorn Ranch and numerous other corners of the West, there are โ€œone rock dams,โ€ โ€œzuni bowls,โ€ โ€œrock mulch rundownsโ€ and other hand-built structures intended to arrest vertical โ€œheadcutsโ€ in ephemeral streambeds.

By facilitating the flow of water and slowing it down, the structures can prevent erosion from spreading uphill. Although the ecological do-gooding tactic relies on simple concepts and materials โ€” essentially well-placed rocks โ€” building it out requires hard physical labor.

A bevy of volunteers flocked to South Pass on June 21 to erect new Zeedyk structures and shore up old ones. 

Jared Oakleaf, Liz Lynch and Lindsey Washkoviak ventured up from Lander. Mark Kot, bad back and all, came from Rock Springs to move rock. Christiansen made the drive from Green River alongside his granddaughter, Camryn Christiansen-Fieock, of Big Piney. On a day off, Wyoming Game and Fish Department habitat biologist Troy Fieseler made the trek from Pinedale and with his son, Cooper.

The rocks were donated, too. Robert Taylor, an avid sage grouse hunter from Washington state, ponied up for the materials the volunteers carefully placed. 

Several of the bunch devoting their Saturday to moving rocks up on South Pass were seasoned. Fieseler even learned the ropes from the techniqueโ€™s namesake himself. 

โ€œThe very first time I did it, we had Bill Zeedyk come out,โ€ he said. โ€œHe taught us to read the landscape.โ€

That 2021 workshop, held at Seedskadee National Wildlife Refuge, imparted Fieseler with lessons he hasnโ€™t forgotten. Protecting uneroded wet meadows is a far more efficient use of time and resources than trying to restore those that have already washed out, he recalled.

Over the last decade, Zeedykโ€™s erosion-control tactics have gained traction in Wyoming and well beyond. The Natural Resources Conservation Serviceโ€™s Sage Grouse Initiative gave the concept its legs, Christiansen said. Now there are thousands of structures dispersed across hundreds of projects, he said.

โ€œEach of these, whatโ€™s its significance?โ€ Christiansen said. โ€œAn individual one, itโ€™s not so much, but when you start doing thousands of these across the West, there is significance.โ€

Enough time has passed since the techniqueโ€™s inception that restoration specialists know it works, thanks to long-term monitoring

The White Acorn Ranchโ€™s Zeedyk structures also have proven hardy and able to withstand the worst that the harsh Wyoming environment can throw their way. Christiansen and his fellow volunteers labored in a corner of the state that got walloped during the winter of 2022-โ€™23 by an unusually hefty snowpack. 

โ€œThis ensured the runoff from the heavy snow,โ€ Christiansen said. โ€œThey dealt with a lot of energy, and handled it. Very few rocks moved.โ€

Christiansen spoke of the rock structureโ€™s resilience on the front end of a day of labor. From a section of state land, he motioned down a draw. 

โ€œThereโ€™s over 20 structures between here and where that slope toes off,โ€ he said. 

Every one of them had been erected by Christiansen, the crews of Zeedyk structure-building volunteers and agency folks that have also chipped in.

Assessing the U.S. #Climate in June 2025 — NOAA

Click the link to read the report on the NOAA website:

Key Point:

A widespread late-June heatwave impacted much of the central and eastern U.S., and brought record-setting temperatures. More than 100 million people across 726 counties experienced record heat from June 22โ€“25.

Map of the U.S. selected significant climate anomalies and events in June 2025

Other Highlights:

Temperature

June 2025 U.S. Mean Temperature Departures from Average Map

The average temperature for the contiguous U.S. (CONUS) in June 2025 was 71.2ยฐF, 2.8ยฐF above the 20th-century average, and ranked seventh warmest in the 131-year record. Temperatures were above average across most of the Lower 48, with much-above-average warmth affecting large areas of the western third of the country, along with parts of the Florida Peninsula, Mid-Atlantic, Northeast and Great Lakes regions. Rhode Island saw its second-warmest June on record and its warmest for nighttime minimum temperatures, which were 5.8ยฐF above average.

Alaskaโ€™s average temperature for June was 50.8ยฐF, 1.6ยฐF above the long-term average and ranking in the warmest third of the 101-year record. While parts of the southeast Panhandle were slightly cooler than average, the North Slope was notably warm at more than 3 degrees above average.

The average temperature for the CONUS during the first half of 2025 (Januaryโ€“June) was 49.6ยฐF, 2.1ยฐF above the 20th-century average, ranking in the warmest third of the 131-year record. All states recorded temperatures above their long-term averages for the six-month period, with much-above-average warmth observed across parts of the West, Southwest and portions of the East Coast. Alaskaโ€™s year-to-date average temperature was 26.8ยฐF, 5.5ยฐF above its long-term average, tying as the fourth-warmest Januaryโ€“June in the 101-year record.

Precipitation

June 2025 U.S. Total Precipitation Percentiles

The average precipitation for the contiguous U.S. in June was 3.22 inches, 0.30 inch above the long-term average, ranking in the wettest third of the 131-year record. Much of the Southwest, the southern and central Plains, the middle and upper Mississippi Valley, parts of the Ohio Valley and Great Lakes region and areas of the Deep South recorded above-average rainfall. In contrast, drier-than-average conditions prevailed from the central West Coast through the Northwest and into the Rockies. The Northwest region experienced its third-driest June on recordโ€”and driest since 2003โ€”with Washington and Oregon each receiving less than half an inch of rain for the month. Parts of north-central California and south-central Washington recorded no measurable rainfall for the entire month.

For the Januaryโ€“June period, the CONUS averaged 15.70 inches of precipitation, 0.40 inch above the long-term average, ranking in the middle third of the 131-year record. Most of the western half of the country, along with a narrow band from the central Plains through the mid-Mississippi Valley and parts of the Southeast, were drier than average. Above-average precipitation was recorded from the southern Plains through the lower Mississippi and Ohio Valleys into the Northeast, as well as in parts of the northern Plains and upper Mississippi Valley.

Alaska received 2.32 inches of precipitation in June, which was near the long-term average. Conditions were drier than average across the eastern interior and North Slope but wetter than normal in the western and southwestern parts of the state. For the first half of the year, Alaska recorded 16.58 inches of precipitation, 2.96 inches above average, marking its fifth-wettest start to the year on record.

Drought

US Drought Monitor map July 1, 2025.

According to the July 1ย U.S. Drought Monitor report, about 32.4% of the contiguous U.S. was in drought, an increase of approximately 2.8% since the beginning of the month. Drought developed or intensified across much of the Northwest through the Rocky Mountains and in small areas of the Alaskan interior. Conversely, drought contracted or was reduced in intensity across parts of the Southwest and southern Texas, the central and northern Plains, the upper Mississippi Valley and parts of Florida.

Monthly Outlook

July temperatures are expected to be above normal across the entire contiguous U.S., with the highest likelihood of warmer-than-average conditions in the Mountain West, southern Texas and throughout much of the Great Lakes and the Northeast. For rainfall, parts of the Northwest and the southern and central Plains are expected to be drier than normal, while the interior East is favored to have a wetter-than-average July. Drought is likely to persist across much of the western U.S. in July, with some further development in the Northwest, while improvement is expected across southeastern Arizona, southern New Mexico and far West Texas, where above-average rainfall is favored.

๐Ÿฅต Aridification Watch ๐Ÿซ

If Lake Powell is like a big thermometer gauging the hydrologic health of the Upper Colorado River Basin, then itโ€™s running a high fever.

In one case, the fever analogy is a bit too literal: The National Park Service has detected high concentrations of cyanotoxins in the reservoir around the mouth of Antelope Canyon, and is warning folks to limit their exposure to the water. Warm water is one of the drivers of cyanotoxin growth.

The surface level peaked out on June 19 at 3,562 feet above sea level, with about 7.8 million acre-feet of storage (or about one-third of its capacity). That means the big, white โ€œbathtubโ€ ring on the sandstone cliffs has grown by about 27 feet in the past year, re-revealing some landforms and rendering some boat ramps unusable. Levels will continue to drop throughout the summer.

This is because more water is leaving the reservoir via downstream releases and evaporation than is flowing into it. Reservoir inflows during June were a mere 883,000 acre feet, or about 41% of the median inflows. Thatโ€™s far lower than the last two years and is only marginally higher than in 2002, 2018, and 2021, some of the worst years on record. And with the water year three-fourths of the way done, only 4.2 million acre-feet has flowed from the Colorado River and its upstream tributaries into the reservoir, setting the stage for a water year total of just about 5.5 million acre-feet โ€” or 2 million acre-feet less than the minimum release from Glen Canyon Dam.

The only good news is that temperatures at the reservoir mostly have been in the 80s or 90s for the past several weeks, which is about normal for this time of year. Oh, and another sorta-kinda silver lining: As the reservoir levels drop, the surface area decreases, reducing the rate of evaporation. Yay?

Inflow volumes at Lake Powell have been pretty skimpy this water year, with June of 2025 delivering just 41% of the median flows for that month. 1983 was the biggest water year on record since Glen Canyon Dam was completed in 1963, and 2002 was the lowest inflows.

Meanwhile, many of the Colorado Riverโ€™s users continue under the illusion that the Colorado River Compact and the Law of the River will trump nature and the reality of diminishing flows.

Take the Imperial Valley in southern California. The Imperial Irrigation District is the single largest water user on the river, consuming some 2.3 million acre-feet during the 2024 calendar year to grow various food crops and a lot of alfalfa. Thatโ€™s about seven times more Colorado River water than all of southern Nevadaโ€™s casinos, hotels, golf courses, and homes consume.

But itโ€™s also about 200,000 acre-feet less than the irrigation district consumed in 2013. Thatโ€™s in part because some farmers are being paid to not irrigate or to irrigate less, often meaning they must fallow their fields, at least temporarily. And some of those farmers have chosen to lease their land โ€” about 13,000 acres โ€” to solar companies for utility-scale energy installations, allowing them to continue to make money off the land without further depleting the Colorado River.

Thanks to Dustin Mulvaney for tipping us off to this resolution on Bluesky.

That irks the Imperial Irrigation Districtโ€™s board, which recently passed a resolutionโ€œopposing the continued expansion of utility-scale solar projects on active or historically farmed agricultural landโ€ in the district. โ€œOur identity and economy in the Imperial Valley are rooted in agriculture,โ€ said IID Board Chairwoman Gina Dockstader, in a written statement. โ€œSolar energy has a role in our regionโ€™s future, but it cannot come at the cost of our farmland, food supply, or the families who depend on agriculture. This resolution is about protecting our way of life.โ€

The resolution doesnโ€™t carry any legal weight, but the IID has a lot of influence, and could easily push the county to ban or heavily restrict solar installations on farmland as dozens of other counties across the nation have done.


Meditations on solar, Joshua trees, and the movement to kill clean energy — Jonathan P. Thompson


Granted, taking land out of agriculture and irrigation has consequences. It can become a weed-choked, dust-spawning expanse. In the Imperial Valley, irrigation runoff feeds the Salton Sea. And, of course, you lose food production and farmworker jobs.

Nevertheless, the resolution seems somewhat short-sighted. It is based on the assumption that the IID will be able to flex its senior water rights in perpetuity, and never have to give up significant amounts of irrigation. It robs farmers of their private property rights, their ability to diversify their income sources, and an opportunity to conserve increasingly scarce water.

And, if the solar installations arenโ€™t built there, they are likely to end up on public land in desert tortoise and other wildlife habitat that could require the removal of hundreds or even thousands of Joshua trees. Worse, it might result in new natural gas or even coal plants to meet the burgeoning demand for power driven by the proliferation of energy- and water-intensive data centers.

And on that note, thereโ€™s Kanab, in south central Utah. Iโ€™ve driven through Kanab many a time, but usually I just roll on through, finding more of interest in Ordervilleor Fredonia or even Colorado City and Hildale. I mean, Orderville does have โ€œHo-Made Pies,โ€ or so the sign declares, and was founded as a bastion of the United Order, the tenets of which were communalism, cooperation, and equal distribution of wealth.

Kanab, meanwhile, was notable to me only as the home of former Utah state representative Mike Noel, who was a Wise Use/Sagebrush Rebel leader of the early 2000s, and I wasnโ€™t going to stop in for a cup of coffee โ€” er, a soda โ€” with the guy. So I failed to notice that the little community was not only growing, but sprawling into the surrounding red-rock desert in the form of upscale resorts and housing communities and even a brand new town. A friend sent me this video, which enthusiastically offers details:

  • There is, for example,ย Catori Canyonย โ€œa premium housing development & luxury gated communityโ€ that โ€œredefines modern indoor-outdoor living.โ€ Prices start at $450,000 โ€” for a bare lot. It also predictably has a pickleball court, which is what I think they mean when they say it โ€œisnโ€™t just home โ€” itโ€™s a lifestyle.โ€ I call that real estate propaganda.
  • Andย Ventana Resort, which is on state trust lands and is described by the Utah Trust Lands Administration as an โ€œambitious project that includes townhomes, affordable housing, nightly rentals, single-family homes, and even a hotel.โ€ The Kane County Water Conservancy District, headed by the aforementioned Mike Noel, had hoped to build a golf course on the land, but pickleball โ€” yes, the development has courts โ€” and four swimming pools won out, apparently. The townhomes are expected to begin at $650,000, according to theย Southern Utah News.
  • The new town? It was originally just a huge subdivision called Willow Preserve Estates, which received county approval (after the county had denied its proposed public infrastructure district). But apparently the developers werenโ€™t content with the limits of the subdivision approval, so they petitioned the state toย incorporate their own municipalityย called Willow, which would allow them to approve their own PID with higher housing density. Kane County commissioners areย miffed. If the state approves the municipality, it will include 1,200 to 1,400 home sites along with commercial areas on a big parcel of land east of Kanab and just south of Hwy 89.

Thatโ€™s a lot of homes; Kanab has about 2,000 households, and that doesnโ€™t count Catori Canyon or Ventana Resorts, let alone Willow. And, if youโ€™re like me, youโ€™re wondering where these folks โ€” along with the other developments with their swimming pools and lawns โ€” are going to get their water.

It appears the answer is: wells. Kanab currently supplies its 5,000 residents with several groundwater wells and springs. Willow will likely get its water from Kane County Water Conservancy Districtโ€™s Johnson Canyon system, which is also fed primarily by groundwater. Which is to say, they arenโ€™t taking it directly out of the Colorado River system, but they are taking it indirectly from the system, since groundwater and surface water is all connected. Plus, aquifers all over the Colorado River Basin are being depleted by over-pumping. Pulling more out of them is not sustainable.

But thatโ€™s not all. Kanab is also about to be home to two new ultra-exclusive resorts in a similar vein as Amangiri, the posh place frequented by the Kardashians and located just outside the (past and possibly present) polygamist community of Big Water, Arizona. 

Canyon Country, my friends, is rapidly being gentrified. 

Kaia, by Outdoor Citizen, bills itself as a โ€œnew ultra-luxury RURAL EB-5 investment opportunity.โ€ That is, if youโ€™d like to migrate to America, just fork out a million or so bucks for one of the 40 planned residences in Johnson Canyon outside Kanab and, voila!, you have permanent U.S. residency. In Europe they call that a โ€œgolden passport.โ€ The projectโ€™s developer is FirstPathway Partners, whose sole purpose is to facilitate these EB-5 visas.

Yeah, the BLM land might be protected for now. But a warning to the rich folks that might want to invest: Utah politicians are leading the charge to turn that lovely โ€œGreenbeltโ€ of public land over to housing developers. So instead of those fetching red rocks, you might one day have a view of a subdivision out your giant front window. And if Sen. Mike Lee and his ilk canโ€™t sell the public land straight out, the Trump administration might just fast-track a uranium or coal mine, AI-crunching data center, or oil and gas development in that greenbelt just a few hundred meters from your luxury home.

The Rundown

  • President Trumpโ€™sย budget billย targets a few water projects while eliminating some climate and environment programs.
  • Agencies move to constrainย environmental reviewsย under NEPA.
  • EPA says it will loosenย wastewater pollution rulesย for thermal power plants later this summer.
  • GAO reviewsย NASAโ€™s major projects, including the third generation of a water-tracking satellite.
  • EPA intends to take public comments on its idea to narrowย state and tribal reviewsย under Section 401 of the Clean Water Act.
  • White House orders higher fees for foreign tourists visitingย national parks.

And lastly, EPAโ€™s internal watchdog notes the risks of rising seas to federally owned Superfund sites.

โ€œIf contaminants from federal facility Superfund sites are released into the surrounding communities, the health, jobs, and environment of millions of U.S. residents may be threatened. Further, the federal funds expended to implement those remedies would have been wasted.โ€ โ€“ Report from the EPA Office of Inspector General that identifies 49 federally owned Superfund sites at risk of flooding from rising seas and increased storm surge.

By the Numbers

$658 Million: Expected baseline cost of the third generation of NASAโ€™s satellite mission that measures changes in the planetโ€™s water storage. The GRACE-C mission is scheduled for July 2029, according to a Government Accountability Office review of NASAโ€™s major projects. Operating for more than two decades, the GRACE satellites have been instrumental in tracking global groundwater depletion.

News Briefs

NEPA Overhaul
Cabinet and other agencies โ€“ including the Interior DepartmentU.S. Department of Agriculture, and Army Corps of Engineers โ€“ announced they will revise their rules for environmental reviews of major projects and prioritize shorter and quicker assessments of potential harms.

The agencies are shortening the administrative timeline for implementing a new rule, arguing that the standard notice-and-comment process would be an unnecessary delay and โ€œcontrary to the public interest.โ€

The Council on Environmental Quality, the White House arm that traditionally oversees NEPA, revoked its regulations in April in response to an executive order promoting domestic energy production. The agencies, now seeking faster, more efficient reviews, are establishing their own rules.

Besides the arrival of the new administration, recent legal rulings have also rearranged the playing field for environmental reviews.

In justifying its action, each agency cited the U.S. Supreme Courtโ€™s ruling in May in Seven County Infrastructure Coalition v. Eagle County, ColoradoThat ruling, in a case which centered on a railroad line in Utah for crude oil, allowed for narrowly focused environmental reviews that assess only a specific project and not the actions โ€“ like upstream oil drilling and downstream oil refining โ€“ it would enable.

Budget Bill
The budget reconciliation bill, which could add $3 trillion to the national debt over the next decade, barely mentioned water directly.

Among the few call outs: The bill delivers $1 billion for surface water storage and water conveyance in the western United States. The money is for projects that increase or restore capacity of Bureau of Reclamation water conveyance systems or increase their use. Increasing reservoir storage capacity โ€“ such as raising Shasta Dam, a Republican-driven idea thatโ€™s been on the table for years โ€“ is also acceptable. The money is available through September 30, 2034.

More broadly, climate and environment programs were chopped. Unobligated Inflation Reduction Act funds โ€“ those not yet committed to a recipient โ€“ were yanked back for programs on climate data, environmental justice block grants, reducing air pollution at schools, and more.

National Parks Fees
President Trump ordered the Interior Department to increase national park entry fees for foreign visitors. The additional revenue would be channeled to infrastructure improvements at the parks or to increase park access.

Still Storm Watching, For Now
NOAA said it would delay by one month the termination of certain storm-tracking satellite data, the Associated Press reports.

Studies and Reports

Superfund Sites at Risk from Rising Seas
The federal government owns 157 Superfund sites. Forty-nine of those sites are at risk of flooding from rising seas and increased storm surge.

The assessment comes from the EPAโ€™s internal watchdog, which published the report to draw attention to federal liabilities related to climate change and the nationโ€™s most toxic sites.

The at-risk Superfund sites are clustered at military sites around Chesapeake Bay, Puget Sound, and San Francisco Bay.

Arizona Groundwater Assessment
The U.S. Geological Survey published a report on water quality in the Coconino aquifer in northern Arizona, where it could be a water source for the Hopi Tribe and Navajo Nation.

On the Radar

Water Quality Permitting
The EPA is considering a rulemaking that would narrow the scope of Clean Water Act reviews undertaken by states and tribes.

These Section 401 reviews have been a target of the Trump administration. Energy companies complain that states have used their review authority to block fossil fuel infrastructure such as natural gas pipelines.

Before the rulemaking, the EPA is asking for public input. The agency opened a docket for written submissions, and it will hold two online events at a time to be announced.

File written comments at www.regulations.gov using docket number EPA-HQ-OW-2025-0272. The deadline is August 6.

Another Slogan Commission
Through an executive order, President Trump established the Presidentโ€™s Make America Beautiful Again Commission.

The commissionโ€™s objectives โ€“ โ€œpromote responsible stewardship of natural resources while driving economic growth; expand access to public lands and waters for recreation, hunting, and fishing; encourage responsible, voluntary conservation efforts; cut bureaucratic delays; and recover Americaโ€™s fish and wildlife populations through proactive, voluntary, on-the-ground collaborative conservation effortsโ€ โ€“ in some ways conflict with the administrationโ€™s desire to cut budgets and greenlight fossil fuel projects.

One of the commissionโ€™s charges is to recommend to the president โ€œsolutions to expand access to clean drinking water and restore aquatic ecosystems to improve water quality and availability.โ€ Stay tuned.

Power Plant Wastewater
Lee Zeldin, EPA administrator, said his agency later this summer will relax wastewater pollution rules for thermal power plants that burn fossil fuel and nuclear fuel.

The Biden administration placed stricter limits on these wastewater discharges last year. In a press release, Zeldin said compliance deadlines would be extended. The agency will also reconsider technological requirements for preventing polluted discharges.

Becky Mitchell and Doug Kenney had much to say at Crested Butte. Just as important may have been what they did not say.

The apple cart of the Colorado River has been upset for 25 years, and Doug Kenney and Becky Michell were on stage June 24 at the Crested Butte Public Policy Forum to talk about the bruised apples.

Thereโ€™s broad understanding that what worked in the past wonโ€™t work in the future. As to what will work โ€” ah, well, that has yet to be resolved. โ€œSo far, we havenโ€™t really been able to pull the demands down as quickly as supplies have been going down,โ€ said Mitchell.

Adding tension to the conversation is another so-so or worse spring runoff in the river. Despite a decent snow year in northern Colorado, yet another early, warm and mostly drier-than-usual spring has produced an anemic projected runoff of a little over 9 million acre-feet. Average runoff into Lake Powell has been 12 million in recent years. The compact governing the river between the three lower-basin states and the four upper basin states assumed at least 20.

Kenney directs the Western Water Policy Program at the University of Colorado Boulderโ€™s Getches-Wilkinson Center. The program puts on a conference each June that is considered one of several must-attend events for those drawn to the unceasing drama about Coloradoโ€™s namesake river.

The river and its tributaries provide water for farms almost to Kansas and Nebraska and, on the west side, to 23 million people crowded along the Pacific Ocean in southern California.

In Crested Butte, Kenney said that unlike other people in Colorado River discussions, whether they represent environmental or agriculture organizations, he enjoys a rare freedom. โ€œI tell people sometimes, I donโ€™t have a dog in the fight, and by that, I just mean I donโ€™t have to represent an interest.โ€

Then he added: โ€œThatโ€™s not entirely true.โ€ He went on to confess that when he sees the Colorado River โ€œsometimes it gives me goosebumps. And Iโ€™m not a goosebumps sort of guy.โ€

Mitchell shared that she was a โ€œsolid B studentโ€ who had grown up in Hawaii before arriving in Colorado to pick up two degrees at the Colorado School of Mines. She worked primarily as a consulting engineer before becoming the director of the Colorado Water Conservation Board. In 2024, Gov. Jared Polis named her to a new position in Colorado government: the stateโ€™s negotiator on Colorado River issues.  Unlike others in such roles, sheโ€™s not a lawyer.

โ€œOften I think of everything as a math problem,โ€ she said. โ€œAnd a lot of what you see with the Colorado River is a math problem. Itโ€™s kind of simple math, almost like just addition and subtraction, not even algebra or multiplication.โ€

The two provided a high-level, yet sometimes detailed overview of the Colorado River during their hour on stage. However, students of the Colorado River, especially about the dramas, might have wanted another hour and the opportunity to ask additional questions.

For example, what do they make of the so-called โ€œnatural flow proposalโ€ that was first formally discussed at a public meeting earlier that day in Arizona. As reported by the Las Vegas Review-Journal, this would base the release of water from Lake Powell on a three-year average of the โ€œnatural flowsโ€ of the river.

In their comments at Crested Butte, Mitchell and Kenney both broadly identified the need for the river to be shared in ways aligned with what Mother Nature is delivering, not a century-old compact.

Later, at a different meeting, Mitchell had this to say: โ€œWhat we know today is that for any approach to work, it must be supply driven, perform well under both dry and varying hydrologies, and adapt to uncertain future conditions fundamental to this โ€˜divorce,โ€™ or how we call it in Colorado, the conscious uncoupling.โ€™โ€

Others might have asked Mitchell about the tensions behind the closed-door sessions โ€” and the things that Kenney mentioned she could not really talk about in a public forum.

Or about the amount of water used to grow hay, including alfalfa, and other fodder crops for livestock. A 2020 study published in Nature Sustainability found that 55% of the water in the Colorado River Basin altogether goes to crops to feed primarily cattle. In the upper basin, itโ€™s much higher.

Mitchell and Kenney did talk about Mead and Powell, the two big reservoirs in the basin, as all Colorado River conversations must.

โ€œThose are the two biggest reservoirs in the United States, and they happen to fall on a river thatโ€™s not even one of the top 20 biggest rivers in the U.S. in terms of volume,โ€ observed Kenney. The reservoirs were close to full 25 years ago. Now, theyโ€™re two thirds empty. โ€œOptimists would say one-third full,โ€ he said.

If you have more water going out than you have coming in, he explained, you have a mass balance problem. โ€œThatโ€™s happening 8 out of 10 years. More water leaves than is coming into the reservoirs under guidelines adopted in 2007. Those interim guidelines govern operations, including how much water is released from the reservoirs and when.

โ€œWhen we talk about Big River issues right now, the Big River issue is getting the system into balance and bringing back the sustainability of the system,โ€ Kenney explained.

Management of the reservoirs was premised on meeting demand. To be more precise, demands of the lower-basin states. Until relatively recently, the lower-basin states were taking an average 10 million acre-feet even if the river delivered only 5 to 10 million acre-feet for the entire basin. Having two big reservoirs upstream allowed them to ignore the winters of scant snow in the headwaters and the rising spring temperatures that spiked evaporation and transpiration.

The first big shock was in 2002, when the river delivered only 3.8 million acre-feet. That was bad, very bad. But the reservoirs still had a lot of water. And there had been bad snow years before. In 1934, for example, the river delivered only 3.9 million acre-feet. And in 1977, a cold but uncommonly snowless winter, it had delivered 4.8 million acre-feet.

A big snow year did not soon follow 2002, so the states, guided by the Bureau of Reclamation, came up with a sort-of short-term set of solutions called the 2007 Interim Guidelines. Those guidelines remain in effect but are to be replaced with new guidelines. Thatโ€™s a way of saying how the river is to be managed and, more precisely, who gets what and when. Theyโ€™re called the post-2026 guidelines.

As were the 2007 guidelines, these will be interim, because the hydrology of the Colorado River Basin is not static. It is changing, with some concern that the river, already slimmed down from its 20th century average, will continue to shrink. The Colorado River Compact that was devised in 1922 to apportion the riverโ€™s waters assumed somewhere around 20 million acre-feet. This century the average has been 12.5 million acre-feet.

โ€œThe math problem is becoming worse,โ€ said Kenney.

It will likely worsen. Some scientists have projected a further decline in decades ahead, conceivably to an average 10 million acre-feet or less.

How to shrink demands to correspond with the shrinking river?

Mitchell offered some thin optimism. Demands have ceased to rise. They have actually declined. The lower-basin states have reduced their take from the river to 7.5 million acre-feet.

Thatโ€™s what the compact apportioned. But again, the compact from 1922 was flawed. It assumed more water than the river has delivered. Because of the two big reservoirs in the deserts of Utah and Arizona, the lower-basin states have been able to get their 7.5 million acre-feet (and more, until relatively recently). Arizona and California take way more than half of the riverโ€™s harvest. And because the upper-basin states were not taking their full allocation, they could get away with it without causing harm.

The 21st century combined with the aridification caused by rising temperatures have forced the issue. Even so, the reckoning has come slowly. The lower basin states did not reduce demand to stay within the compact until forced to by a declared shortage in August 2021.

While the decision was not a surprise to veteran Colorado River watchers, it vaulted the Colorado River troubles high into the national consciousness. The story ran on the front page of the New York Times: โ€œIn a First, U.S. Declares Shortage on the Colorado River, Forcing Water Cuts.โ€ Arizona farms took the brunt of this declaration, but as the Times noted, wider reductions loomed as climate change continues to affect flows into the river.

The upper-basin states have been averaging 4.4 to 4.5 million acre-feet, far less than the 7.5 million acre-feet apportionment in the compact. How much they take depends upon how much it snows and rains.

โ€œWe have highs and lows because of hydrology. That can shift a lot. A really good example is from 2021 to 2022. Our use was 4.9 (million acre-feet), and then it went down to 3.9 the following year. That wasnโ€™t because weโ€™re amazing people.โ€

It was, Mitchell explained at Crested Butte, as she does in all of her talks, because the upper basin is limited by what Mother Nature actually delivers. The upper basin has no big dams upstream to serve as an aqua bank account. It has to moderate demand based on what kind of snow โ€” and rain โ€” year occurs.

Some 92% of all the water in the Colorado River originates in the upper basin states, including the Yampa River, seen here emerging from Cross Mountain Canyon in northwest Colorado. Photo/Allen Best

When thereโ€™s insufficient water, the state engineer in Colorado and his district engineers cut off water users, mostly ranchers irrigating grasses.

The compact struck among the four-upper basin states in 1948 used a more common-sense approach for how to allocate the 7.5 million acre-feet in the 1922 compact. It allocated the water among the four states based on proportions. Colorado gets a little more than half โ€” and uses most of it. Wyoming has never come close to developing its share. Regardless, the rule of percentages makes sense for an uncertain hydrology.

โ€œWe realized real quickly that Mother Nature reigned supreme,โ€ said Mitchell. I would be in big trouble if I said the lower basin should do the same. I think they should, but theyโ€™re not there yet.โ€

Mitchell used an analogy to describe the difficult transition for the lower basin. It is much harder to take candy from a baby after they have it,โ€ she said.

โ€œItโ€™s going to be hard for them, and my heart goes out to them. But we have an example up here of how it works. Seniors work with juniors,โ€ she explained, using the shorthand for senior and junior water uses under the prior appropriation system governing water use in Colorado and most Western states. Ag works with environment interests, utilities with agriculture, and so on. They cut deals in advance of water-short years.

โ€œWe have examples of how to make it work. You have a budget. You have to work within it. Thatโ€™s the deal. And sometimes that budget might fluctuate.โ€

โ€œWeโ€™ve not lost all of our junior water-right holders in Colorado because of one bad year or two bad years or three bad years, in a row, because we figure out how to make it work. And what we are saying to the lower basin is figure out where the deals are to be made.

And she drew upon her childhood for another dynamic.

โ€œWhat my mom always said is, you can have anything you want, but you canโ€™t have everything you want.โ€

Translated to the lower basins, that means โ€œyou canโ€™t have chip factories and the largest agriculture in the world and golf courses and pools and Scottsdale and whatever.  You can have the capability to have a strong economy, a sustainable system. You just canโ€™t have it all.โ€

The federal government, through the Bureau of Reclamation, an agency housed within the Department of Interior, built the dams. Reclamation manages the dams. As Mitchell said, they turn the spigots. The onus is on the states to create a solution, an agreement of how to share the shrinking river, but the federal government could step in, if forced to. Mitchell said the feds donโ€™t want to.

โ€œThey really want a consensus deal with the seven states,โ€ she said. Thatโ€™s a hard thing, because thereโ€™s no way to do this without change. The math is the math. The facts are the facts. Thereโ€™s not the 50 million acre-feet in these reservoirs that there were when these (2007) guidelines started. And so the consensus is harder.โ€

Mitchell said she wouldnโ€™t disparage those who created the now obviously flawed 2007 guidelines. Climatologists had suggested only a 3% probability of the runoff that has happened since then would come to pass.

โ€œWhat weโ€™re trying to create through this federal process is something that can handle all the hydrologies. How do we all suffer when the river is suffering? How do we all benefit when the river is flush? And what does benefit look like? Thatโ€™s different in the upper basin than in the lower basin.โ€

The federal government in this case has been nudging the states toward agreement.

โ€œTheyโ€™re trying to say, โ€˜You know, you might be able to open up different project funding if you guys can get to a deal.โ€™ We know we need a deal. Iโ€™m not going to promise you that weโ€™re going to get there, but it is a goal. And (the federal agencies) are part of that goal. They donโ€™t want to make the hard decisions of cutting people off. They are the water masters in the lower basin. They can turn the valves, and thatโ€™s their role.โ€

Added Kenney: โ€œTypically the states are happiest when the federal government is silent, (but) sometimes itโ€™s helpful to have a federal government that is throwing out some ultimatums and some deadlines and some threats.โ€

In the last six months, the federal involvement in the negotiations has grown, and it might grow yet. But a big part of the process โ€” as Mitchell had said โ€” is that the states need to be coming up with their wish list for Congress for consideration next spring.

โ€œSo there is a federal role,โ€ Kenney summarized. โ€œIt evolves based on how the states are doing. But the tradition is you want the feds to stay away until itโ€™s time for someone to write the check.โ€

MItchell had the last word. She again pointed to the meager runoff from this yearโ€™s upper-basin rivers, source of 92% of the riverโ€™s water. Runoff is projected at a little more than 5 million acre-feet into Powell, which is to release 7.48 million acre-feet to the lower basin.

Again, itโ€™s a match problem. And it could get worse.

โ€œIf next year looks anything like this year, or even as a 12 million acre-foot river, actions absolutely have to be taken., and those actions are going to be greater than anybody has put on the table voluntary.โ€

Judge’s ruling keeps #Thornton water pipeline project moving forward — The #FortCollins Coloradan #PoudreRiver #SouthPlatteRiver

July 7, 2025

Key Points

  • A Larimer County judge ruled in favor of Larimer County commissioners, upholding their approval of a permit for Thornton’s 10-mile pipeline project.
  • Save The Poudre, an environmental group, sued the county, arguing the commissioners didn’t properly consider the ‘Poudre River option.’
  • Save The Poudre is considering an appeal, while Thornton says it continues to focus on providing water to its residents.

The city of Thornton is the true winner in a recent court ruling focused on the pipeline it’s planning to build in Larimer County to bring more water to its residents. The lawsuit was filed a year ago by Save The Poudre,ย an environmental advocacy group. Its target was theย Larimer County commissioners, who had approved a permit for construction of the pipeline.

On July 3, Larimer County District Court Judge Michelle Brinegar ruled that commissioners were justified in their decision to approve the application for 10 miles of pipeline through the county…In its lawsuit, Save The Poudre asked the judge to vacate the board’s decision to approve the pipeline. The nonprofit alleged that commissioners didn’t adequately follow the county’s standards for these kinds of applications. Specifically, Save The Poudre contends that commissioners should have required Thornton to present a plan for the so-called Poudre River option, which would have conveyed the water through the Poudre River downstream of Thornton’s current diversion point…But commissioners concluded that while they could encourage the Poudre River option, they couldn’t require it. Brinegar sided with commissioners, saying they can’t compel Thornton to present all possible alternatives, only those that are reasonable.

June 26, 2025

The clock is ticking for seven states to figure out how theyโ€™ll share dwindling water in the Colorado River for the foreseeable future. In a meeting at the Utah State Capitol Thursday [June 26. 2025], the riverโ€™s four Upper Basin state commissioners further embraced the idea of a โ€œdivorceโ€ with their Lower Basin neighbors โ€” anย idea also floated at a meeting in eastern Utah last week, as reported by Fox 13.

โ€œToday we stand on the brink of system failure,โ€ said Becky Mitchell, the commissioner for Colorado. โ€œWe also stand on the precipice of a major decision point.โ€

…negotiations between the four Upper Basin states, which includes Utah, Colorado, Wyoming and New Mexico, have been in a standstill with the remaining three Lower Basin states for more than a year. The Interior Departmentโ€™s acting assistant secretary for water and science, Scott Cameron, has met with leadership in the seven states that use Colorado River water since April, working to broker a deal.

โ€œWe all have to live in the physical world as it is,โ€ he said, โ€œnot as we might hope it will be.โ€

On Thursday, Cameron presented water managers with a deadline. The Interior Department plans to release a draft environmental impact statement evaluating different alternatives for the riverโ€™s future in December, which will then open to public comment. The department will make its final decision on how to proceed by June of 2026.

โ€œThe goal is to essentially parachute in a seven-state deal as the preferred alternative,โ€ Cameron said.

For that to work, the states will need to reach an agreement by Nov. 11. By Feb. 14, theyโ€™ll need to hand over the details of their plan. Whatever the states decide on, Cameron reminded commissioners, will likely take an act of Congress and new policy adopted by most of the affected statesโ€™ legislatures…

The idea of framing the future relationship of the river users as a โ€œdivorceโ€ was first pitched by the Lower Basin states, Mitchell said. Under that proposal, the Upper Basin states would release water from Lake Powell based on the average natural flow measured at Leeโ€™s Ferry, a point just downstream of the reservoir and upstream of both Grand Canyon National Park and Lake Mead.

โ€œIf done correctly,โ€ Mitchell said, โ€œit should provide the opportunity for the Upper and Lower basins to manage themselves, with the only real point of agreement being the Powell release.โ€

Study from 2020 Shows #GlobalWarming Intensifying Extreme Rainstorms Over North America — Bob Berwyn (InsideClimateNews.org)

Last night’s storm (July 30, 2021) was epic — Ranger Tiffany (@RangerTMcCauley) via her Twitter feed.

June 2, 2025

The current warming trajectory could bring 100-year rainstorms as often as every 2.5 years by 2100, driving calls for improved infrastructure and planning.

New research showing how global warming intensifies extreme rainfall at the regional level could help communities better prepare for storms that in the decades ahead threaten to swamp cities and farms. 

The likelihood of intense storms is rising rapidly in North America, and the study, published Monday in the Proceedings of the National Academy of Sciences, projects big increases in such deluges.

โ€œThe longer you have the warming, the stronger the signal gets, and the more you can separate it from random natural variability,โ€ said co-author Megan Kirchmeier-Young, a climate scientist with Environment Canada.

Previous research showed that global warming increases the frequency of extreme rainstorms across the Northern Hemisphere, and the new study was able to find that fingerprint for extreme rain in North America.

โ€œWeโ€™re finding that extreme precipitation has increased over North America, and weโ€™re finding thatโ€™s consistent with what the models are showing about the influence of human-caused warming,โ€ she said. โ€œWe have very high confidence of extreme precipitation in the future.โ€ 

At the current level of warming caused by greenhouse gasesโ€”about 1.8 degrees Fahrenheit above the pre-industrial averageโ€”extreme rainstorms that in the past happened once every 20 years will occur every five years, according to the study. If the current rate of warming continues, Earth will heat up 5.4 degrees by 2100. Then, 20, 50 and 100-year extreme rainstorms could happen every 1.5 to 2.5 years, the researchers concluded.

โ€œThe changes in the return periods really stood out,โ€ she said. โ€œThat is a key contributor to flash flooding events and it will mean that flash flooding is going to be an increasing concern as well.โ€

Better Science, Better Forecasts

The 2013 floods in Boulder, Colorado that killed nine people and caused more than $2 billion in property damage are a good example of how such climate studies can help improve flood forecasts, said Kevin Trenberth, a climate scientist with the National Center for Atmospheric Research in Boulder, Colorado.

โ€œThat was an exceptional event and the rain was like tropical rain. The radars greatly underestimated the magnitude as a result,โ€ said Trenberth who returned to his home in Boulder during the floods with a broken foot, only to have to climb on his roof to direct the gushing water away from his house.

From: The Great Colorado Flood of September 2013

A subsequent study found that the rain resulted from an unusual atmospheric brew over Colorado. Mountain thunderstorms mingled with a juicy atmospheric river from the tropics, dropping up to 17 inches of rain in a few days, nearly as much as Boulderโ€™s annual average total. Human-caused climate change โ€œincreased the magnitude of heavy northeast Colorado rainfall for the wet week in September 2013 by 30%,โ€ the study found.

A separate study concluded that global warming actually decreased the likelihood of the 2013 floods. The conflicting results hint at the complexities of climate research, but, since then, the influence of human-caused climate change on extreme weather has become more clear.

The risks will continue to increase as the atmosphere warms, said David R. Easterling, a climate extremes researcher and director of the U.S. National Climate Assessment. โ€œThe detection has been there for a while on a lot of extreme events,โ€ said Easterling, who was not involved in the new study. โ€œWeโ€™re going to see increases in extreme events, and we need to be prepared.โ€ 

Easterling said most current infrastructure, such as dams and bridges, was designed based on rainfall values from the mid- to late-20th century and was not built to withstand the more frequent extreme rains identified by the new research.

โ€œThere are going to be much more damaging floods that are going to wash out a lot of the infrastructure,โ€ he said. โ€œYouโ€™ll see more floods and bigger floods and major impacts to our civil engineering infrastructure.โ€

According to the Environmental Protection Agencyโ€™s website, data from the National Oceanic and Atmospheric Administration indicates that the percentage of total precipitation coming from intense single day events has increased significantly since about 1980, with nine of the top 10 years for extreme one-day precipitation events occurring since 1990. The EPAโ€™s precipitation indicator website also shows similar changes at the global scale.

Warmer Air, More Moisture and Shifting Storm Tracks

One way to visualize the planetโ€™s climate system is as a heat-driven pump that tries to balance the planetโ€™s energy by circulating it around the globe and cycling it from oceans, to land, to the atmosphere. Global warming puts more heat into the pump and that energy is manifested elsewhere in the system. For instance, for every 1.8 degrees Fahrenheit of warming, the atmosphere holds 7 percent more moisture that can fall as extreme rain, hail or snow. 

But global warming can increase rainfall by much more than 7 percent in individual events. In Hurricane Harvey, for example, the estimated boost in rainfall was about 30 percent, said Trenberth.

โ€œThe outcome depends on the kind of storm. If the rainfall is in or near the center of the storm, as for a hurricane, then the extra oomph from the latent heat release intensifies the storm and makes it bigger and longer lasting,โ€ he said. โ€œThis can also happen for an individual thunderstorm.โ€ He was not involved in the new study.

For storms outside the tropics, the most rain happens away from the center, which doesnโ€™t necessarily make the rain more intense, but can affect the way the storms move and develop, he added.

โ€œThis is the atmospheric river phenomenon and requires the weather situation to remain stuck for a bit, as a river of moisture from the subtropics, like the pineapple express, pours into a region,โ€ he said. A 2019 study showed that atmospheric rivers cause most of the flood damage in the Western United States already, and global warming is projected to intensify those events.

In addition to simply having more moisture in the atmosphere, global warming may also drive more extreme rainfall by shifting global weather patterns, said climate scientist Peter Pfleiderer, with Climate Analytics in Berlin. 

In a 2019 study published in the journal Nature Climate Change, Pfleiderer and other scientists looked at how global warming changes weather patterns in ways that make heat waves, droughts or rainstorms longer or more intense. With global temperature increases of 2.7 to 3.6 degrees Fahrenheit (the range to which the Paris climate agreement hopes to limit warming), periods of heavy rain would increase 26 percentโ€”the most of all the weather phenomena studiedโ€”the research found.

Friederike Otto, acting Director of the Environmental Change Institute at Oxford, said new research showing how global warming affects extreme rain regionally complements studies that identify the effect on individual events.

As a co-investigator with World Weather Attribution, Otto has been involved in a series of recent studies looking at how global warming affects droughtsheat waves and extreme rain. The strongest signal, as she expected, was with heat waves, but she expects rain events โ€œfar outside the observations so far.โ€

โ€œOne thing I only started to realize in the last year, is how important attribution is for making projections,โ€ she said. Climate attribution studies show how the warming of the planet makes some extremes more likely, and intensifies other weather events. Linking measurements of what actually happens with model predictions โ€œgives you more confidence that the changes are because of climate change,โ€ she said.

Escalating Impacts Require Adaptation and Resilience

Floods caused by extreme rain are among the costliest climate-related disasters. A NOAA compilation of billion-dollar disasters lists a long string of deadly catastrophes caused, at least in part, by extreme rain. These include the January 2020 floods in New York, Michigan and Wisconsin, where significant damage along the shoreline of Lake Michigan was compounded by extremely high water levels in the lake, as well as a lack of seasonal ice cover.

In 2019, extreme and persistent spring rainfall in the Midwest led to one of the costliest inland flooding events on record. Floodwaters inundated millions of acres of farms, along with numerous cities and towns and Offut Air Force Base in Nebraskaโ€”the third U.S. military base to be damaged by a billion-dollar disaster in a six-month period. In all, that wave of flooding caused $10.9 billion in damage, NOAA estimated.

Earlier this month, persistent heavy rains contributed to the failure of a dam in Michigan, and Easterling said heavy rains were also implicated in the 2017 Oroville Dam failure that cost $1.1 billion and forced the evacuation of 180,000 people. The flooding caused by record rainfall from Hurricane Harvey in 2017 was a big part of the $125 billion worth of damage caused by the storm.

Extreme rain can also have an impact on a smaller scale. In mountainous areas, heavy precipitation over even a small area can be disastrous. In the Rocky Mountains, such cloudbursts have caused toxic floods of acidic water from abandoned mines, and in the European Alps, scientists say extreme rains are unleashing larger and more destructive rockfalls and landslides.

โ€œWe are going to get more intense, extreme precipitation, this is one of the things we are sure about,โ€ said Hannah Cloke, a University of Reading natural hazards researcher and hydrologist specializing in flood forecasting. 

The United Kingdom has been hit repeatedly by extreme rain in recent years, including Storm Desmond in 2015, which was linked with global warming and caused at least $550 million in damage, flooding nearly 10,000 homes and businesses. Cloke said the recent flooding has apparently even shaped her daughterโ€™s world view. For a recent school assignment, the nine-year-old used plastic bottles to build a floating house reminiscent of the movie Waterworld.

โ€œMost of the design standards for storm infrastructure are not high enough for the predictions, or even what weโ€™re seeing right now,โ€ she said. โ€œWe have to get away from the idea that you can just carry on business as usual. We have to adjust our expectations of what could happen. We need to get people out of harmโ€™s way and be realistic about where we live.โ€

Cloke said the certainty of increased extreme rainfall means that communities have to adapt by creating or restoring natural areas that can soak up the rains in the uplands, and cities need to be redesigned with green roofs and other measures to prevent flood waters from piling up and destroying property. More and more, flood experts are thinking in terms of socio-hydrology, she said.

โ€œYou canโ€™t just look at the water, at the heavier rain, and how fast itโ€™s running down the rivers,โ€ she said. โ€œItโ€™s about how humans and water interact at all levels, and how politics controls where the water is. Itโ€™s about who is at risk of flooding and whether those people have any agency to reduce the risk.โ€ 

New research like the PNAS study that shows the regional fingerprint of global warming on extreme rainfall can help reduce the risk, she said, because it enables better short-term forecasts.

July 1, 2025

At Thistle Whistle Farm in Hotchkiss, farmer Mark Waltermire grows a wide variety of crops on his 16 acres.

“A lot of greens, onions, shallots, cabbage, kohlrabi, carrots, beets, parsnips, burdock root, scorzonera and saltapie, and then heirloom tomatoesโ€ฆ” he lists when prompted.

Waltermire’s farm is in Colorado’s North Fork Valley, in the West Elk Range of the Rockies. The growing season is short, and the climate is semi-arid. As Waltermire notes, climate change is impacting how he operates…Waltermire is considering a solution [to the warmer atmosphere] that would create a dual use of his land. He wants to build five acres of solar panels on his land โ€” about a megawatt of power โ€” and continue growing his tomatoes, eggplants, potatoes, and leafy greens under them. The solar panels would provide shade, something that would benefit his many crops, as well as his goats, chickens, and ducks…It’s called agrivoltaics, combining agriculture with photovoltaic, or solar, panels…[Byron Kominek] explains that selling the energy from these solar panels can help farmers, even during bad years.

A jarring pothole — Allen Best (BigPivots.com)

Josh Shipley rides a Harley and drives a Jeep. He says ending federal tax credits for solar may upend his business.

Josh Shipley rides a Harley in his spare time and likes to take his family on off-road Jeep trips and has hunted across North America.

On Wednesday morning, Shipley had to fight tears as he talked about the impact on his business, Alternative Power Enterprises, and the families of the employees of the earthquake-inducing bill now being debated in Congress.

โ€œRemoving these tax credits at the end of the year is going to be extremely detrimental,โ€ he said on a press call orchestrated by the staff of U.S. Sen. John Hickenlooper. โ€œWe actually donโ€™t believe weโ€™re going to be able to stay in business.โ€

The business is based in Ridgway, one of two smaller solar installation companies there. It has eight employees, and they have five spouses and seven children. They do work from Paonia to Silverton.

โ€œItโ€™s not just eight people that are going to be affected by this,โ€ he said. The business, he explained, has been around for 30 years, and in recent years it has been able to start helping low-income families to get solar.

โ€œI think in the last three years, 120 families in our area have benefited,โ€ he said. โ€œIf I canโ€™t survive, the other parts of this business are going away. I canโ€™t be there to help those individuals.โ€

Shipley said he bought the business in 2020 with the assumption that federal tax credits would be phased out, but not until 2032.

The bill, he said, is a tragedy for U.S. energy policy.

โ€œRepublicans are always talking about independence and being โ€” sorry, Iโ€™m getting a little emotional โ€” getting and being dominant in our industries. This is how we become energy dominant. Itโ€™s not just wind. Itโ€™s not just solar. Itโ€™s not just natural gas plants. Itโ€™s not just nuclear power plants.

โ€œIt takes every single one of these technologies for us to create that โ€” excuse me โ€” and to keep these families โ€” Iโ€™m sorry, excuse me โ€” but it will take all of these forms of energy to create that dominance,โ€ he said. This billโ€™s going to kill that. There are no ifโ€™s, andโ€™s, or butโ€™s about it. Small businesses will go out of business because of it.  There will not be the workforce that is going to be required to create that energy dominance later, when theyโ€™ve realized what theyโ€™ve done.โ€

Hickenlooper, who had arrived late the night before from Washington D.C., touched on several provisions of what he called the โ€œcruel, reckless billโ€ that the Senate had passed on Sunday morning.

โ€œThis was a vote that would strip 17 million Americans, including many, many children, of their health care, push more than 300 rural hospitals to close, gut investments in affordable clean energy,โ€ he said โ€œIt would expand our national debt at a level that we have never imagined before, and all this just to accommodate these lavish tax cuts for wealthy Americans, most of whom arenโ€™t asking for the tax cuts. It is a form of madness, fiscal madness, and I think itโ€™s cruel.โ€

U.S. Sen. John Hickenlooper called the bill passed by his fellow senators โ€œcruel.โ€ Credit: Allen Best/Big Pivots

Later, he explained that the bill would gut the Inflation Reduction Act of 2022. โ€œIt was a major step towards addressing climate change, and now itโ€™s been itโ€™s like running into a brick wall,โ€ he said.

โ€œWeโ€™re going to lose over a million jobs in this country. I mean, these are careers, hundreds of billions of dollars of lost GDP, lost wages. Weโ€™re going to see the cost of electricity go up. Weโ€™re going to kill new renewable energy that prevents blackouts just when weโ€™re in the process of trying to accommodate AI. We need more energy. Weโ€™ve got over 8,000 solar jobs just in Colorado.โ€

Speaking later, KC Becker described the bill as triggering an all-hands-on-deck moment for the solar industry in Colorado. In April, she became the executive director of the Colorado Solar and Storage Association.

โ€œPeople are nervous from the smallest companies to the largest companies. Itโ€™s been a whirlwind,โ€ she said. โ€œThe bill was expected to get better in the Senate. It actually got worse in the Senate because of the excise tax (on solar and wind production, now discarded).โ€

Right now, many solar providers are working hard, because they have inventories of panels. But the demand, if this bill gets passed as new constructed, will cause demand to drop off a cliff after Dec. 31.

The big question in Colorado โ€” and part of the national dialogue โ€” is whether any of Coloradoโ€™s representatives in Congress who are Republicans will buck the marching orders of President Donald Trump. Rep. Gabe Evans and Jeff Hurd, both freshman and both Republican, voted for the bill after saying nice things about renewable energy.

Fort Lupton-based Evans was barely elected last November from the Eighth District north of Denver, his first run at Congress. Grand Junction-based Hurd has a more comfortable position in the Third District, which covers much of the Western Slope plus much of southern Colorado.

Also speaking on the webcast press conference were the four Democrats who are members of Coloradoโ€™s delegation in the House of Representatives, Gov. Jared Polis, and various individuals from health care providers, most from more rural parts of Colorado.

The take-away message was that this bill will dramatically hurt poorer people who are unable to afford health care without governmental assistance. That, however, can also be true in urban areas.

U.S. Rep. Brittany Pettersen was momentarily reduced to fighting tears when she talked about the giant erosion of programs to help low-income people. โ€œWhen I think about my mom who works a low-wage job, without access to medical care,โ€ said Pettersen, who then choked up. For her, this was politics, but the bill was also deeply personal.

July 2, 2025

On the evening of June 24, the GWCโ€™s Doug Kenney joined Becky Mitchell, Coloradoโ€™s lead negotiator on Colorado River matters, at the Crested Butte Public Policy Forum for a conversation about current and future Colorado River issues.  Well over 100 people packed the Center for the Arts for the public event that in previous years has featured speakers as varied as Ted Turner, Sandra Day Oโ€™Connor, and the GWCโ€™s Senior Fellow Anne Castle.

The primary focus of discussion was how โ€œbig riverโ€ issuesโ€”that is, the changing rules determining how Colorado River supplies are shared amongst the seven statesโ€”impact the availability of water on Coloradoโ€™s West Slope.   This required a review of the three numbers in the basin that increasingly are out of step: the amount of water entering the system each year through snowmelt and rain; the amount of water consumed by water users throughout the basin; and the amount of consumptive use that has been promised to water users in the Colorado River Compact and other laws. This mismatch of supplies, demands and allocations is not a new problem, but is of particular urgency now as Lakes Powell and Mead are two-thirds empty, the EIS process for new determining new reservoir operations is well underway, and the current year runoff is shaping up as one of the worst in decades.

The conversation was led by Julie Nania, an icon in Crested Butte for her work with High Country Conservation Advocates in protecting Mt. Emmonsโ€”the so-called โ€œRed Ladyโ€โ€”from development into a molybdenum mine, as well as her service on the Board of Directors of the Upper Gunnison Water Conservancy District and as Executive Director and Faculty Chair of the Coldharbour Institute based at Western Colorado University.  Julie began her career at Colorado Law (class of 2011), which included a post-graduate fellowship with the GWC from 2013-2014 working on tribal water rights. Julie stands as a great example of the GWCโ€™s ongoing influence in protecting the resources and places that we all value.

Data Dump: Abandoned oil and gas wells in #NewMexico: Also: Public lands continue to take a beating, despite one small victory — Jonathan P. Thompson (LandDesk.org)

A serious mess, also known as the NE Hogback #53 well and associated infrastructure. Chuza, the most recent owner of the site in the Horseshoe Gallup oil field in northwestern New Mexico, went bankrupt. That left New Mexico and federal taxpayers holding the cleanup bill. The site has been partially reclaimed, but only partially. Jonathan P. Thompson photo.

July 2, 2025

๐Ÿ›ข๏ธย Hydrocarbon Hoedownย ๐Ÿ“ˆย Data Dumpย ๐Ÿ“Š

A new report on New Mexicoโ€™s abandoned and orphaned oil and gas wells presents an alarming and expensive scenario for the state. It reveals that while the industry generates a lot of revenue for the state, cleaning up its mess is also poised to cost state and federal taxpayers hundreds of millions of dollars. No, this report was not put out by an environmental or progressive advocates, but by the stateโ€™s legislative finance committee.

New Mexico has been an oil and gas hotspot for more than a century, during which drillers have sunk at least 121,000 wells, mostly in the San Juan and Permian basins in the northwest and southeast portions of the state. Newly drilled wells typically kick out a large volume of oil and/or gas during the first months after drilling, generating a lot of cash for their operators and for state coffers, and helping to push production numbers for the state through the roof.

But the wells are soon afflicted with whatโ€™s known as the decline curve, meaning that the longer they pump, the less they pump. You know, itโ€™s kind of like aging in people. Eventually, aging will render all oil and gas wells into low-producing stripper wells (Iโ€™m not sure how this analogy extends to the human realm, but hey โ€ฆ) that kick out less than 10 barrels of oil per day. Thousands of New Mexico wells are extreme strippers, producing one barrel or less daily. Yet they continue to spew methane, hydrogen sulfide, and volatile organic compounds at the same as or an even higher rate than their younger, more vital counterparts.


A trip through a sacrifice zone: The Horseshoe Gallup oilfield — Jonathan P. Thompson


This is problematic for a number of reasons. For one, the operators of stripper wells are likely to be smaller, less financially secure companies, and itโ€™s easier and cheaper for them to keep the wells in a nearly inactive state โ€” during which the wells continue to ooze pollutants into the air and groundwater โ€” than to decommission, plug, and reclaim them. It may make economic sense to abandon these wells, or for the companies to cease to exist and โ€œorphanโ€ the wells, leaving them to the state or federal taxpayers to clean up, since reclamation bonds are woefully inadequate. And, finally, these wells generate almost nothing in production taxes, meaning that they arenโ€™t contributing much to the stateโ€™s conservation fund, a portion of which is used to clean up abandoned and orphaned wells.


Saga of an Oil Well (The Horseshoe Gallup Field Sacrifice Zone Part II) — Jonathan P. Thompson


The near constant drone of drilling for over a century has resulted in a near-constant addition of low- to non-producing wells to New Mexicoโ€™s rosters. While responsible and financially solvent companies plug and reclaim their own wells, many smaller operators simply walk away.

New Mexicoโ€™s Oil Conservation Division is currently responsible for plugging close to 1,000 abandoned and orphaned wells, including 700 on state or private land, and for remediation and reclamation of an additional 500 well sites and 18 infrastructure sites (such as leaky tank batteries).

Detail of interactive map showing orphaned, inactive, and low-producing wells on state and private land in the San Juan Basin (this leaves out hundreds of additional such wells on federal lands).

At recent rates, plugging them will take close to a decade, not including remediation/reclamation. OCD is also responsible for remediation and reclamation of an additional 500 well sites and 18 infrastructure sties. In total, plugging, remediation, and reclamation of all currently orphaned wells and infrastructure on state and private land is estimated to cost a minimum of $208 million, and likely more. And thatโ€™s just for now.

The report goes on to say: โ€œโ€ฆ in addition to wells the state already has legal authority to plug, thousands of inactive and low-producing wells are at risk of being orphaned, potentially increasing the stateโ€™s liability by many orders of magnitude.โ€ There are about 1,400 inactive at high risk of being orphaned on state and private land, according to the OCD. And there are thousands more that are extremely low-producing wells โ€” putting out less than one barrel of oil equivalent per day โ€” for which the โ€œexpected cost of cleanup far exceeds predicted future revenues, increasing their risk of being orphaned.โ€

And the kicker: โ€œAltogether, the stateโ€™s current and near-future liability for well plugging and site remediation is estimated to be between $700 million and $1.6 billion.โ€

More data from the report:

  • 38,817 Number of stripper wells, meaning they produce less than 10 barrels of oil-equivalent daily, in New Mexico, making up about 64% of the stateโ€™s active wells. This number will continue to increase.
  • $100,000 Average cost to plug single oil and gas well.
  • 450% Percent the average state-contracted cost to plug an oil and gas well in New Mexico has increased since 2019.
  • $250,000 Maximum amount of financial assurance an operator in New Mexico must post to cover the costs of plugging and reclaiming its wells. This cap applies whether the operator has five wells or 500 wells, meaning it actually provides almost no financial assurance whatsoever.
  • $46.4 million Amount spent by the New Mexico Oil Conservation Division to plug and reclaim 360 wells and associated infrastructure between 2019 and 2024.
  • 9% Percent by which the cost of plugging a gas well exceeds that of an oil well. Most of the wells in the San Juan Basin are gas wells.
  • $208 million Estimated cost to New Mexico to plug, remediate, and reclaim all existing orphaned and abandoned wells and infrastructure on state and private land.
  • $5.6 million Amount in financial assurance associated with orphaned wells or their operators, meaning most of the costs will be shouldered by the taxpayers โ€” either via the state reclamation fund or federal grants.
  • $66.7 million April 2025 balance of New Mexicoโ€™s oil and gas reclamation fund (which is funded by a portion of conservation tax revenues).
  • $6 million Tax revenue New Mexicoโ€™s 3,024 wells producing less than 1BOE/day would generate with the West Texas Intermediate oil price at $70/barrel (itโ€™s currently lower than that). Plugging and reclaiming those same wells would cost an estimated $531 million to $885 million. โ€œThe vast majority of the wellsโ€”87%โ€”are owned by private companies whose financial health is difficult for regulators to assess.โ€
  • $1.6 millionย Amount New Mexico paid in 2024 to plug six of Ridgeway Arizonaโ€™s wells under a 2023 settlement agreement with the company. Under the agreement, the state pays to plug 299 of the companyโ€™s wells, and the company reimburses the state $2 for each barrel of oil it sells, with a minimum payment of $30k per month. But at current rates, the total cost to plug the remaining wells could be $60 million or more, meaning it would take the company as long as 170 years to pay it off.

๐ŸŒต Public Lands ๐ŸŒฒ

By now youโ€™ve probably heard that Sen. Mike Lee pulled his public land sell-off provision from the budget reconciliation bill that the Senate just passed following intense backlash. And perhaps youโ€™re planning on celebrating the salvation of Americaโ€™s public lands on July 4.

Thereโ€™s so much BS in Leeโ€™s statement. How, for example, does selling public land to developers keep it from being ruined for the next generation? It doesnโ€™t, it just locks up that land for every generation except those that can afford to buy a house in the new subdivision that would go there. Public land is not โ€œlocked away from the people who live there.โ€ But it would be locked away if it was privatized. And while there is no property tax on public lands, there are federal payments in lieu of taxes, or PILT, which a county can use to fund schools and search and rescue operations. Plus, public lands generate billions in revenue for gateway communities through public land usersโ€™ sales and lodgers taxes and local spending.

Well, I hate to be Mr. Buzzkill, but while this victory may be sweet, it does little to offset the bitterness brought by continuing attacks on public lands, along with democracy, morality, decency, and, well, America, itself, this Independence Day week.

The โ€œBig, Beautiful Billโ€ perpetuates and amplifies the massive transfer of wealth from low- and middle-income and working-class Americans to the richest 10%. It will slash Medicaid and other vital programs Americans have paid into and rely upon, while also dismantling tribal sovereignty. And yet, it will also drive up the deficit by trillions of dollars due to additional spending on the military industrial complex, which is reaching its tentacles further into immigration enforcement, wildlife blocking border walls, deportations, and $450-million-per-year concentration camps. With Trump threatening to revoke citizenship from U.S.-born citizens whom he considers threats (e.g. Zohran Mamdani and Elon Musk), those camps may end up housing his political opponents. I really hate to make this comparison, but that is some severe Nazi-esque nastiness.

The Senateโ€™s bill gives more handouts to the oil and gas and coal industries, while revoking tax credits for wind and solar power, which could kill those industries when they are needed most.

And yes, some of you may cheer a weaker renewable-energy industry, since it will mean fewer utility-scale installations blanketing the desert. I get that. But it will also hurt rooftop solar and larger installations on big box stores, over parking lots, or in fallow agricultural land, brownfields or other appropriate sites. A western Colorado farmerโ€™s plan to install solar panels to generate electricity and shade his crops, for example, is imperiled by the GOPโ€™s plans.

This at a time when strain on the power grid is exponentially increasing due to the outsized demand of more and more AI-powering, hyperscale data centers. That power will come from somewhere, and if itโ€™s not solar or wind or batteries, then itโ€™s likely to be from pollution-intensive coal and natural gas (mined and drilled from public lands), fish-killing hydropower, or new nuclear reactors (that will require uranium mined from public lands).

And keep in mind, oil and gas leasing and mining claims represent a sort of quasi-privatization of public lands. Sure, the government retains title to the land, but the corporations get access to the minerals within, can rip the land apart to get to them, and can cut off public access with the necessary permits. With its accelerated 14-day โ€œenergy emergencyโ€ permitting process, the Trump administration is making it a heck of a lot easier for corporations to mine, drill, and otherwise develop public lands, sans public input. The latest beneficiaries include:

  • NorthWestern Energy, which was given the Bureau of Land Management green light to build aย 74-mile natural gas pipelineย between Helena and Three Forks, Montana.
  • Ormat got the BLM go-ahead to move forward on three separate geothermal projects in Nevada:
    โ€ข Exploration work at theย Diamond Flat projectย near Fallon;
    โ€ข Upgrades at theย McGinness Hills projectย in Lander County;
    โ€ข Exploration drilling at theย Pinto Geothermal Projectย near Denio.

Iโ€™m not suggesting that these are horrible projects that shouldnโ€™t have been approved. Geothermal holds a lot of potential as a relatively clean, round-the-clock baseline power source, and these are merely upgrades and exploration, not full on developments. Still, geothermal development and even exploration have impacts and can affect groundwater aquifers, springs, and wetlands. Land agencies should have as much time as it takes to adequately analyze potential effects, and tribal nations should be consulted and have time to do their own analysis. And if itโ€™s happening on public lands, then the public deserves to know about it and have an opportunity to weigh in. None of that is possible under this 14-day permitting process.

So, yeah, happy Fourth of July, yโ€™all and welcome to the Divided States of Project 2025. And on that note, the Land Desk will be taking the rest of the week off.

July 3, 2025

{The Colorado Water Conservation Board] unanimously agreed Tuesday to hear out Front Range water operatorsโ€™ concerns about a Western Slope plan to purchase historic Colorado River water rights.

The Colorado River Water Conservation District, which represents 15 Western Slope counties, negotiated a $99 million deal to purchase water rights tied to the century-old Shoshone Power Plant, owned by a subsidiary of Xcel Energy.

The River District and the Front Range groups โ€” Aurora Water, Denver Water, Colorado Springs Utilities and Northern Water โ€” all want to maintain the historical flows past Shoshone to provide predictable water supplies long into the future. They mainly disagree about the amount of water involved. Front Range providers say, if the number is too high, it could hamper their ability to provide water to millions of people.

In June, the Front Range water managers asked the Colorado Water Conservation Board to hold a hearing to air concerns. That hearing will be held during the boardโ€™s meeting, Sept. 16-18.

โ€œWe look forward to the hearing, and we appreciate the effort and the time that you and the staff have put into this effort,โ€ Andy Mueller, the River Districtโ€™s general manager, said during the board meeting Tuesday. โ€œ[We] look forward to finishing this in September.โ€

The decision Tuesday also opened up a seven-day period, ending July 9, for others to ask to join the September hearing. The board will share updates with the public on its website.

The hearing is part of a larger [CWCB Instream and water court] process to decide whether Shoshone Power Plantโ€™s water rights can become an environmental water right, called an instream flow right. These rights aim to keep water in rivers to help aquatic ecosystems.

Photo: 1950 โ€œPublic Service Damโ€ (Shoshone Dam) in Colorado River near Glenwood Springs Colorado.

In this case, the environmental water right would focus on a 2.4-mile stretch between Shoshoneโ€™s intake dam, which takes water out of the Colorado River, and the end of its penstocks, which return all of Shoshoneโ€™s water to the river. The power plant is tucked into Glenwood Canyon along Interstate 70 a few miles east of Glenwood Springs.

At times, the power plant sucks nearly all of the Colorado Riverโ€™s flow โ€” depending on the amount of water in the river above the dam โ€” through its turbines before returning it to the river channel. When this happens, the 2.4-mile stretch immediately below the dam is reduced to a narrow channel of water.

The environmental flow right would allow water managers to keep more water in that stretch of the river to help fish and other aquatic species. If approved, it would be the largest, most influential instream flow right in the stateโ€™s portfolio. The Colorado water board has until Sept. 18 to make its decision.

The Colorado River District wants to purchase the water rights as part of a larger plan to permanently shore up water supplies for Western Slope communities, which have long worried that Shoshoneโ€™s flows could change if Xcel decided to shut down the power plant or sell the water rights.

The district has a purchase agreement with Xcel Energy to buy the rights and lease the water back to Xcel to generate electricity. One of the terms of the deal is getting the instream flow use approved by the state.

The Front Range water providers and water managers want to prevent any changes to Shoshoneโ€™s water rights from harming their water supplies.

Shoshoneโ€™s water rights are like the bottom blocks in a game of Jenga: change to the rights could cause ripple effects statewide, in part, because of their age, location and amount of water.

Shoshoneโ€™s oldest water right can impact up to 10,600 other upstream water rights because of the plantโ€™s geographic location, according to the Colorado Division of Water Resources. Those junior water users include Front Range water managers, like Denver Water and Northern Water, that send water to millions of people.

Colorado transmountain diversions via the State Engineer’s office

They are also tied to numerous, carefully negotiated agreements that dictate how water flows across both western and eastern Colorado.

The Front Range water operators want to resolve their concerns about the historical flows through Shoshone during the instream flow approval process this summer.

The Colorado River District says their questions can be resolved during the subsequent water court proceedings, where opposing parties will have another opportunity to voice their concerns and make sure their water supplies arenโ€™t negatively impacted.

โ€œWe are deeply concerned that the Front Range entities requesting this contested hearing are asking the CWCB to encroach on the jurisdiction of water court,โ€ the district said in a prepared statement Tuesday.

This Week’s Drought Summary

Over the past week, scattered heavy rains fell over parts of the central Great Plains and Upper Midwest. Rain amounts were especially heavy in parts of Nebraska and Minnesota, where locally 8 or more inches of rain fell. These rains helped to alleviate drought and abnormal dryness in some areas. A few areas of the Dakotas, Minnesota, Indiana and Illinois that missed heavier rains saw localized degradations. Heavy monsoonal rain and thunderstorms also occurred in parts of west Texas and New Mexico, leading to some improvements to ongoing drought and abnormal dryness there. Meanwhile, most areas west of the Continental Divide remained dry or mostly dry. This continued dry weather led to further degradation in drought and abnormal dryness, especially in the Northwest, where severe and extreme drought developed or expanded in coverage. Conditions in the Southeast and central Gulf Coast were mostly quiet this week, though a few areas in east Tennessee and southern Louisiana saw localized abnormal dryness develop given short-term precipitation deficits and declining soil moisture. Heavier rains fell across parts of Florida, leading to some reduction in drought and abnormal dryness coverage in the Florida Peninsula. Well-above-normal temperatures occurred in the Ohio Valley, Mid-Atlantic and Lower Great Lakes regions, where temperatures ranging from 4-8 degrees above normal, and locally 10 degrees hotter than normal, were common. The Northwest was also warmer than normal this week, with most areas checking in with warm anomalies of 2-6 degrees. Southeast New Mexico and west Texas finished the week 2-8 degrees cooler than normal owing to rain and clouds from the North American Monsoon, which became much more active this week.

A mix of improvements and degradations occurred across Hawaii, where vegetation and streamflows responded to recent rainfall or lack thereof.

Scattered heavier showers fell across parts of Alaska, while some locations that missed out saw fire danger increase, leading to a mix of improvements and degradations.

Short-term rainfall deficits continued to build in north-central and south-central Puerto Rico, leading to localized increases in abnormal dryness coverage…

High Plains

Very heavy rain fell across parts of southwest and central Nebraska, which extended into portions of northern Kansas (north of Interstate 70) and portions of west-central and eastern South Dakota. Significant flash flooding occurred from rain amounts locally exceeding 8 inches in Grand Island, Nebraska, while very heavy rain, locally in excess of 5 inches, fell in parts of eastern South Dakota, where significant tornadoes also occurred on June 28. Heavier rain amounts fell in parts of south-central and northeast Colorado as well, though most of the heavier totals were in the 1-3 inch range. Primarily dry weather occurred west of the Continental Divide in Colorado and Wyoming. Temperatures across the region were mostly near normal to 2-4 degrees above normal, though parts of the eastern Dakotas were a few degrees cooler than normal. In areas that received heavy rain, soil moisture and precipitation deficits were alleviated and widespread improvements to ongoing drought or abnormal dryness occurred, including a two-category improvement in central Nebraska where some of the weekโ€™s heaviest rains fell. Meanwhile, degradations occurred in northwest Colorado and western Wyoming, where soil moisture and streamflow deficits mounted amid growing precipitation deficits…

Colorado Drought Monitor one week change map ending July 1, 2025.

West

Heavy monsoonal rains fell this week in parts of New Mexico, excluding the far northwest. Elsewhere, this weekโ€™s weather was almost entirely dry. Combined with warmer-than-normal temperatures (mostly by 2-6 degrees) in the Northwest states, this led to widespread degradation in drought and abnormal dryness for central and northern Utah, Idaho, parts of northern and much of western Montana, and Washington. Very low streamflows and large short-term precipitation deficits contributed to widespread expansion of severe and extreme drought in western Montana and adjacent Idaho. Short-term severe drought also occurred in parts of central and north-central Washington, where deficits in precipitation and streamflow continued to grow. In much of New Mexico, excluding the far west and northwest portions, near- or below-normal temperatures were common this week along with some heavier rainfall amounts exceeding 2 inches (locally exceeding 5 inches). The improved soil moisture and lessened precipitation deficits led to widespread improvements to ongoing drought and abnormal dryness in southeast, southwest and north-central New Mexico. Exceptional drought expanded slightly along part of the Arizona-New Mexico state line where deficits in groundwater and precipitation continued to mount…

Heavy monsoonal rains fell this week across portions of west Texas, with local amounts of 2-3 inches or more. Heavy rains of 2-3 inches or more also fell across parts of northeast Oklahoma, and southwest Tennessee. Elsewhere, rainfall amounts of at least 2 inches were less common, while southern Arkansas and northern Louisiana, northwest Oklahoma and portions of central Texas saw mostly dry weather this week. In west Texas, under the monsoonal rainfall, temperatures were 4-8 degrees cooler than normal in some areas. Elsewhere across the region, temperatures were mostly 2-4 degrees warmer than normal in Arkansas and northern Mississippi, while temperatures were mostly 2-6 degrees warmer than normal in Tennessee. Outside of Texas, the South region remained almost entirely free of drought or abnormal dryness. However, around a few localized areas of short-term precipitation and soil moisture deficits, a few small areas of abnormal dryness developed in southern Louisiana and eastern Tennessee. In west Texas, heavy rains from the North American Monsoon helped to partially alleviate short- and long-term precipitation deficits and improve soil moisture quantity…

Looking Ahead

The National Weather Service Weather Prediction Center is forecasting a few areas of rainfall exceeding 1 inch for the period through the evening of Monday, July 7. Localized 1-inch or greater totals are possible in locations in New Mexico, northwest Texas, central and eastern Oklahoma, northern Kansas and Nebraska into the Upper Midwest and northern Great Plains, western Montana, and the Florida Peninsula, perhaps extending to the Southeastโ€™s Atlantic coastline as a weather disturbance moves through. Heavy rain amounts exceeding 3 inches are forecast in portions of the Florida Peninsula, especially along much of its Gulf coast. Mostly dry weather is expected from the Intermountain West to the Pacific Ocean and across much of south Texas, Mississippi, Alabama, Georgia and the southern Mid-Atlantic.

For July 8-12, the National Weather Service Climate Prediction Center forecast strongly favors warmer-than-normal temperatures in the western Contiguous U.S., especially west of the Continental Divide. Warmer-than-normal temperatures are also favored in the eastern U.S., especially from Virginia southward to Florida. Near- or below-normal temperatures are favored for parts of the southern and central Great Plains and western portions of the Midwest. Below-normal precipitation is favored from northern Arizona across Utah, Nevada, southern Idaho, much of Oregon and southwest Washington. Above-normal precipitation is slightly favored in southern Arizona and southern and eastern New Mexico eastward across much of the Contiguous U.S.

In Alaska, above-normal precipitation is favored across much of the state, especially in the eastern half and excluding the far west reaches. Cooler-than-normal temperatures are favored across most of Alaska, especially central and eastern portions of Alaska.

In Hawaii, warmer-than-normal temperatures are favored from Molokai westward. Above-normal precipitation is favored throughout Hawaii.

June 18, 2025

The banks of a previously degraded 1-mile stretch of Rifle Creek are now thick with willows and cottonwoods, and have signs that deer, elk and beavers are once again frequent visitors. 

This summer marks 10 years since an ambitious, multiphase riparian restoration project began on John Powersโ€™ ranch, located north of Rifle and off Colorado 325. Since 2016, the property has been a worksite of the Colorado Natural Heritage Program, which has cataloged species; replaced invasive Russian olive, thistles and weeds with native trees, flowers, shrubs and grasses; and trained the next generation of scientists and conservationists on how to restore the health of a stream. 

On June 3, Powers, who is a self-described lover of the outdoors, along with friend and associate Janna Six, as well as interns from CNHP, hosted a public-outreach day with conservation professionals who worked on the project, including representatives from local governments, agencies and nonprofit organizations, for a tour of the project. Powers called it a living lab for education and hopes it can serve as a demonstration project for other ranches in the area that want to control erosion. 

A decade ago, the banks of the creek were severely eroded โ€” bare of vegetation in places and steep. Part of the reason for these conditions is the upstream Rifle Gap Reservoir, which was completed in 1967. Sediment collects behind the dam, meaning the water released downstream is clean and erosive, cutting into the streambanks. The three-phase project sought to remedy that.

โ€œRifle Creek used to be shallow, allowing horse-drawn hay wagons to cross it,โ€ Powers said in a written response to questions from Aspen Journalism. โ€œAfter the Rifle Gap Reservoir was built, severe erosion occurred downstream, making creek banks vertical and 12-15 feet deep.โ€

Powers said the goals of the project are to improve the habitat for songbirds, pollinators and wildlife; increase carbon sequestration, including cultivating healthy soil and minimizing erosion; and maintain the economic benefits of a working ranch while enhancing the ecological condition of the riparian area.

The thousands of native plants were put in over a three-year intensive effort by volunteers and interns, led by plant ecologist Lisa Tasker. Some are protected by fencing from wildlife and livestock until they become established, and are watered with a drip irrigation system. 

โ€œMy hope is that I live long enough that I wonโ€™t be able to see one side of the creek from the other side of the creek,โ€ Powers told tour participants.

David Anderson, director and chief scientist at CNHP, said conditions on the ranch have changed dramatically for the better over the past decade due to the restoration work.

โ€œWeโ€™re seeing a lot more birds now that thereโ€™s some woody structure,โ€ he said. โ€œThereโ€™s just a whole different suite of wildlife that can utilize the riparian area there now.โ€

Anderson added that with the new vegetation providing shade to cool the stream, conditions for native fish will improve.

Restoration tactics take time

Rivers and wetland habitats comprise a small amount of Coloradoโ€™s land area, but they are of outsize importance to wildlife. Improving the health of Rifle Creek is a focus of the Middle Colorado Watershed Council, a nonprofit organization that works to protect and improve watershed health. Between 2015 and 2019, the creek was the subject of a watershed assessment, which looked primarily at water quality. 

The council has also been implementing the goals of its Riparian Restoration Implementation Plan, which spans the entire Colorado River watershed from Glenwood Springs to DeBeque. But the stretch of Rifle Creek from below Rifle Gap Reservoir to its confluence with the Colorado River is a main concern. 

โ€œWe wonโ€™t be able to restore the whole thing right away,โ€ said Kate Collins, executive director of the council, referring to plans to conduct additional restoration work along Rifle Creek beyond the Powers ranch. โ€œBut what we want to do is identify certain projects that are either the most urgent or perhaps they are the most low-hanging fruit โ€” in other words, thereโ€™s the best opportunity for restoration.โ€ 

The health of many streams across the Western Slope is impacted by erosion, invasive species and agriculture. Collins said the tactics for fixing them are often low-tech, such as replacing invasives with native plants. 

โ€œSome of these techniques are being widely used, and this Rifle Creek project could be a model for others,โ€ she said, referring to the Powers ranch restoration project.

Future plans for the ranch include another bio blitz in 2026 in which CNHP interns will document as many species of plants and animals on the ranch as possible over a 24-hour period and compare the results to their bio blitzes in 2016 and 2017. 

Powers and Anderson are also interested in potentially building what are called beaver dam analogs (BDAs), which are human-made structures that mimic beaver dams, helping to slow streamflow and keep water on the landscape. These temporary wood structures usually consist of posts driven into the streambed with willows and other soft materials weaved across the channel between the posts. Environmental groups and local governments are using BDAs to improve stream health and wildlife habitat.

โ€œWeโ€™re really interested in doing some of those,โ€ Anderson said. โ€œI hope that maybe next year or in another subsequent year that weโ€™ll work with the interns to build some of those structures right in Rifle Creek.โ€

For Powers, the Rifle Creek restoration on his ranch has been a passion project that keeps a riparian area thriving, as well as adapting to climate change and a future with less water. Collins sees the project as a step toward reconnecting the community to its local waterway.

โ€œ(Rifle Creek) is a vital part of what runs through that town and that community, and itโ€™ll be exciting to see what positive ecological changes those bring about to virtually everything else,โ€ Collins said…

Front Range concerns over purchase of Colorado River rights on Western Slope to get hearing: #ColoradoRiver District wants to buy Shoshone Power Plant rights to protect water flows — The #Denver Post #COriver #aridification

July 2, 2025

Four major Front Range water providers โ€” Denver Water, Aurora Water, Colorado Springs Utilities and Northern Water โ€” will presentย their concerns about the purchaseย of theย Shoshone Power Plantย water rights by the Colorado River District during a hearing in September before the Colorado Water Conservation Board. The board during a special meeting Tuesday decided to hold the hearing to hash out the urban utilitiesโ€™ concerns about how much water should be allocated to the right. The board must decide by September whether to approve the new use of the water right proposed by the district…The Colorado River District, a taxpayer-funded agency that works to protect Western Slope water,ย in 2023 announced a $99 million dealย to buy the water rights from Xcel Energy, which owns the power plant. The purchase โ€” a decades-long effort by the district โ€” will ensure that water will continue to flow west past the plant tucked into Glenwood Canyon and downstream to the towns, farms and others who rely on the Colorado River even if the century-old power plant were decommissioned.

Each of the Front Range utilities have said they do not oppose the purchase itself. They do, however, question the river districtโ€™s calculations of how much water has been used historically under the rights. Under Colorado water law, that number will determine how much water must flow through the plant in the future. The districtโ€™s calculations are too high, the four utilities argue, and would leave them with less water from the Colorado River for their own uses. The river district has repeatedly said it plans to maintain the status quo and will not use more water than has been used in the past. Disputes about the amount of water historically used under a water right should be settled in water court, the districtโ€™s general manager Andy Mueller said Tuesday in a statement.

โ€œWe are deeply concerned that the Front Range entities requesting this contested hearing are asking the CWCB to encroach on the jurisdiction of water court,โ€ Mueller said. โ€œโ€ฆ We believe maintaining public trust relies on following the right path and avoiding political intrusion.โ€

Western public land sale axed from Senate budget bill: #Utah U.S. Senator Mike Lee withdraws a plan that could have auctioned more than a million acres — Angus M. Thuermer Jr. (WyoFile.com)

Utah Sen. Mike Lee withdrew his land-sale provision from the Senate reconciliation budget bill Saturday evening.

โ€œI was unable to secure clear, enforceable safeguards to guarantee that these lands would be sold only to American families โ€“ not to China, not to Blackrock, and not to any foreign interest,โ€ Lee posted on X. โ€œFor that reason, Iโ€™ve made the decision to withdraw the federal land sales provision from the bill.โ€

The Republican had sought to require the sale of Bureau of Land Management property โ€” owned by all Americans โ€” to help Western communities resolve affordable housing worries. Critics said existing laws allow such sales and that the measure violated a core western value โ€” public access to public land.

More than one million acres of public land were at stake. The provision required the government to auction the property rapidly and with curtailed public involvement.

Conservationists, hunters and anglers and outdoor recreation businesses erupted in virtual applause after Lee conceded. Opposition across the West stirred thousands to rally in support of continued ownership of and access to their publicly owned property.

โ€œPublic lands are the cornerstone of our conservation legacy,โ€ Chris Wood, president and CEO of Trout Unlimited said in a statement heralding the provisionโ€™s demise.

Others were less reserved.

โ€œTotal faceplant,โ€ wrote Land Tawney, co-chair of American Hunters & Anglers.

โ€œHe rewrote his scheme multiple times,โ€ Tawney said of Lee. โ€œAnd tonight? He yanked his own language from the bill,โ€ Tawney wrote in a statement.

President Trumpโ€™s First EPA Promised to Crack Down on Forever Chemicals. His Second EPA Is Pulling Back — Anna Clark (Propublica.org)

July 2, 2025

EPA Administrator Lee Zeldin claims to prioritize combatting long-lasting chemicals called PFAS. Despite this, the agency has delayed enforcement of standards and terminated over $15 million in funding for โ€œforever chemicalsโ€ research.

ProPublica is a nonprofit newsroom that investigates abuses of power. Sign up to receiveย our biggest storiesย as soon as theyโ€™re published.

One summer day in 2017, a front-page story in the StarNews of Wilmington, North Carolina, shook up the lives of hundreds of thousands of people. The drinking water system, it said, was polluted with a contaminant commonly known as GenX, part of the family of โ€œforeverโ€ PFAS chemicals.

It came from a Chemours plant in Fayetteville, near the winding Cape Fear River. Few knew about the contaminated water until the article described the discoveries of scientists from the Environmental Protection Agency and a state university. Given that certain types of PFAS have been linked to cancer, there was widespread anxiety over its potential danger.

In the onslaught of legal action and activism that followed, the EPA during President Donald Trumpโ€™s first term took an assertive stance, vowing to combat the spread of PFAS nationwide.

In its big-picture PFAS action plan from 2019, the agency said it would attack this complex problem on multiple fronts. It would, for example, consider limiting the presence of two of the best-known compounds โ€” PFOA and PFOS โ€” in drinking water. And, it said, it would find out more about the potential harm of GenX, which was virtually unregulated.

By the time Trump was sworn in for his second term, many of the planโ€™s suggestions had been put in place. After his first administration said PFOA and PFOS in drinking water should be regulatedstandards were finalized under President Joe Biden. Four other types of PFAS, including GenX, were also tagged with limits.

But now, the second Trump administration is pulling back. The EPA said in May that it will delay enforcement on the drinking water limits for PFOA and PFOS until 2031, and it will rescind and reconsider the limits on the other four. Among those who challenged the standards in court is Chemours, which has argued that the EPA, under Biden, โ€œused flawed science and didnโ€™t follow proper rulemaking proceduresโ€ for GenX.

These EPA decisions under Trump are part of a slew of delays and course changes to PFAS policies that had been supported in his first term. Even though his earlier EPA pursued a measure that would help hold polluters accountable for cleaning up PFAS, the EPA of his second term has not yet committed to it. The agency also slowed down a process for finding out how industries have used the chemicals, a step prompted by a law signed by Trump in 2019.

At the same time, the EPA is hampering its ability to research pollutants โ€” the kind of research that made it possible for its own scientists to investigate GenX. As the Trump administration seeks severe reductions in the EPAโ€™s budget, the agency has terminated grants for PFAS studies and paralyzed its scientists with spending restrictions.

Pointing to earlier announcements on its approach to the chemicals, the EPA told ProPublica that itโ€™s โ€œcommitted to addressing PFAS in drinking water and ensuring that regulations issued under the Safe Drinking Water Act follow the law, follow the science, and can be implemented by water systems to strengthen public health protections.โ€

โ€œIf anything,โ€ the agency added, โ€œthe Trump administrationโ€™s historic PFAS plan in 2019 laid the groundwork for the first steps to comprehensively address this contamination across media and we will continue to do so this term.โ€

In public appearances, EPA Administrator Lee Zeldin has pushed back on the suggestion that his agency weakened the drinking water limits on GenX and similar compounds. Future regulations imposed by his agency, he said, could be more or less stringent.

โ€œWhat we want to do is follow the science, period,โ€ he has said.

That sentiment perplexes scientists and environmental advocates, who say there is already persuasive evidence on the dangers of these chemicals that linger in the environment. The EPA reviewed GenX, for example, during both the first Trump and Biden administrations. In both 2018 and 2021, the agency pointed to animal studies linking it to cancer, as well as problems with kidneys, immune systems and, especially, livers. (Chemours has argued that certain animal studies have limited relevance to humans.)

Scientists and advocates also said itโ€™s unclear what it means for the EPA to follow the science while diminishing its own ability to conduct research.

โ€œI donโ€™t understand why we would want to hamstring the agency that is designed to make sure we have clean air and clean water,โ€ said Jamie DeWitt, a toxicologist in Oregon who worked with other scientists on Cape Fear River research. โ€œI donโ€™t understand it.โ€

Delays, Confusion Over PFAS

Favored for their nonstick and liquid-resistant qualities, synthetic PFAS chemicals are widely used in products like raincoats, cookware and fast food wrappers. Manufacturers made the chemicals for decades without disclosing how certain types are toxic at extremely low levels, can accumulate in the body and will scarcely break down over time โ€” hence the nickname โ€œforever chemicals.โ€

The chemicals persist in soil and water too, making them complicated and costly to clean up, leading to a yearslong push to get such sites covered by the EPAโ€™s Superfund program, which is designed to handle toxic swaths of land. During the first Trump administration, the EPA said it was taking steps toward designating the two legacy compounds, PFOA and PFOS, as โ€œhazardous substancesโ€ under the Superfund program. Its liability provisions would help hold polluters responsible for the cost of cleaning up.

Moving forward with this designation process was a priority, according to the PFAS plan from Trumpโ€™s first term. Zeldinโ€™s EPA describes that plan as โ€œhistoric.โ€ And, when he represented a Long Island district with PFAS problems in Congress, Zeldin voted for a bill that would have directed the EPA to take this step.

The designation became official under Biden. But business groups, including the U.S. Chamber of Commerce, and organizations representing the construction, recycling and chemical industries, sued. Project 2025, The Heritage Foundationโ€™s playbook for the new administration, also questioned it.

Zeldin has said repeatedly that he wants to hold polluters accountable for PFAS, but his EPA requested three delays in the court case challenging the Superfund designation that helps make it possible.

The agency said in a recent motion it needed the latest pause because new leadership is still reviewing the issues and evaluating the designation in context of its โ€œcomprehensive strategy to address PFOA and PFOS.โ€

The EPA also delayed a rule requiring manufacturers and importers to report details about their PFAS use between 2011 and 2022. An annual bill that sets defense policy and spending, signed by Trump in his first term, had charged the EPA with developing such a process.

When Bidenโ€™s EPA finalized it, the agency said the rule would provide the largest-ever dataset of PFAS manufactured and used in the United States. It would help authorities understand their spread and determine what protections might be warranted.

Businesses were supposed to start reporting this month. But in a May 2 letter, a coalition of chemical companies petitioned the EPA to withdraw the deadline, reconsider the rule and issue a revised one with narrowed scope.

When the EPA delayed the rule less than two weeks later, it said it needed time to prepare for data collection and to consider changes to aspects of the rule.

In an email to ProPublica, the agency said it will address PFAS in many ways. Its approach, the agency said, is to give more time for compliance and to work with water systems to reduce PFAS exposure as quickly as feasible, โ€œrather than issue violations and collect fees that donโ€™t benefit public health.โ€

The court expects an update from the EPA in the Superfund designation case by Wednesday, and in the legal challenges to the drinking water standards by July 21. The EPA could continue defending the rules. It could ask the court for permission to reverse its position or to send the rules back to the agency for reconsideration. Or it could also ask for further pauses.

โ€œItโ€™s just a big unanswered question whether this administration and this EPA is going to be serious about enforcing anything,โ€ said Robert Sussman, a former EPA official from the administrations of Presidents Bill Clinton and Barack Obama. As a lawyer, he now represents environmental groups that filed an amicus brief in PFAS cases.

Back in North Carolina, problems caused by the chemicals continue to play out.

A consent order between the state and Chemours required the manufacturer to drastically reduce the release of GenX and other PFAS into the environment. (The chemicals commonly called GenX refer to HFPO-DA and its ammonium salt, which are involved in the GenX processing aid technology owned by Chemours.)

Chemours told ProPublica that it invested more than $400 million to remediate and reduce PFAS emissions. It also noted that there are hundreds of PFAS users in North Carolina, โ€œas evidenced by PFAS seen upstream and hundreds of miles awayโ€ from its Fayetteville plant โ€œthat cannot be traced back to the site.โ€

PFAS-riddled sea foam continues to wash up on the coastal beaches. Chemours and water utilities, meanwhile, are battling in court about who should cover the cost of upgrades to remove the chemicals from drinking water.

Community forums about PFAS draw triple-digit crowds, even when theyโ€™re held on a weeknight, said Emily Donovan, co-founder of the volunteer group Clean Cape Fear, which has intervened in federal litigation. In the fast-growing region, new residents are just learning about the chemicals, she said, and theyโ€™re angry.

โ€œI feel like weโ€™re walking backwards,โ€ Donovan said. Pulling back from the drinking water standards, in particular, is โ€œdisrespectful to this community.โ€

โ€œItโ€™s one thing to say youโ€™re going to focus on PFAS,โ€ she added. โ€œItโ€™s another thing to never let it cross the finish line and become any meaningful regulation.โ€

A letter dated April 29, 2025, notifying Michigan State University about the termination of a grant for research into PFAS, one day after the EPA said in a press release that it was committed to combating PFAS contamination by, in part, โ€œstrengthening the science.โ€ Credit: Obtained by ProPublica

Research Under Fire

The EPA of Trumpโ€™s first term didnโ€™t just call for more regulation of PFAS, it also stressed the importance of better understanding the forever chemicals through research and testing.

In a 2020 update to its PFAS action plan, the EPA highlighted its support for North Carolinaโ€™s investigation of GenX in the Cape Fear River. And it described its efforts to develop the science on PFAS issues affecting rural economies with โ€œfirst-of-its-kind funding for the agriculture sector.โ€

Zeldin, too, has boasted about advancing PFAS research in an April news release. โ€œThis is just a start of the work we will do on PFAS to ensure Americans have the cleanest air, land, and water,โ€ he said.

At about the same time, though, the agency terminated a host of congressionally appropriated grants for PFAS research, including over $15 million for projects focused on food and farmlands in places like Utah, Texas and Illinois.

Scientists at Michigan State University, for example, were investigating how PFAS interacts with water, soil, crops, livestock and biosolids, which are used for fertilizer. They timed their latest study to this yearโ€™s growing season, hired staff and partnered with a farm. Then the EPA canceled two grants.

In virtually identical letters, the agency said that each grant โ€œno longer effectuates the program goals or agency priorities. The objectives of the award are no longer consistent with EPA funding priorities.โ€

The contrast between the agencyโ€™s words and actions raises questions about the process behind its decisions, said Cheryl Murphy, head of Michigan Stateโ€™s Center for PFAS Research and co-lead of one of the projects.

โ€œIf you halt it right now,โ€ she said, โ€œwhat weโ€™re doing is weโ€™re undermining our ability to translate the science that weโ€™re developing into some policy and guidance to help people minimize their exposure to PFAS.โ€

At least some of the researchers are appealing the terminations.

About a month after PFAS grants to research teams in Maine and Virginia were terminated for not being aligned with agency priorities, the agency reinstated them. The EPA told ProPublica that โ€œthere will be more updates on research-related grants in the future.โ€

Even if the Michigan State grants are reinstated, there could be lasting consequences, said Hui Li, the soil scientist who led both projects. โ€œWe will miss the season for this year,โ€ he said in an email, โ€œand could lose the livestock on the farm for the research.โ€

Federal researchers are also in limbo. Uncertainty, lost capacity and spending restrictions have stunted the work at an EPA lab in Duluth, Minnesota, that investigates PFAS and other potential hazards, according to several sources connected to it. As one source who works at the lab put it, โ€œWe donโ€™t know how much longer we will be operating as is.โ€

The EPA told ProPublica that itโ€™s โ€œcontinuing to invest in research and labs, including Duluth, to advance the mission of protecting human health and the environment.โ€

Meanwhile, the agency is asking Congress to eliminate more than half of its own budget. That includes massive staffing cuts, and it would slash nearly all the money for two major programs that help states fund water and wastewater infrastructure. One dates back to President Ronald Reaganโ€™s administration. The other was spotlighted in a paper by Trumpโ€™s first-term EPA, which said communities could use these funds to protect public health from PFAS. It trumpeted examples from places like Michigan and New Jersey.

The EPA lost 727 employees in voluntary separations between Jan. 1 and late June, according to numbers the agency provided to ProPublica. It said it received more than 2,600 applications for the second round of deferred resignations and voluntary early retirements.

โ€œThese are really technical, difficult jobs,โ€ said Melanie Benesh, vice president for government affairs at the nonprofit Environmental Working Group. โ€œAnd the EPA, by encouraging so many employees to leave, is also losing a lot of institutional knowledge and a lot of technical expertise.โ€

The shake-up also worries DeWitt, who was one of the scientists who helped investigate the Cape Fear River contamination and who has served on an EPA science advisory board. Her voice shook as she reflected on the EPAโ€™s workforce, โ€œsome of the finest scientists I know,โ€ and what their loss means for public well-being.

โ€œTaking away this talent from our federal sector,โ€ she said, will have โ€œprofound effects on the agencyโ€™s ability to protect people in the United States from hazardous chemicals in air, in water, in soil and potentially in food.โ€

June 30, 2025 North American #Monsoon Drought Status Update: Wet Start for the Monsoon Over #Drought-Stricken Southwest — NOAA

Click the link to read the drought update on the NOAA website:

The North American Monsoon brings summer precipitation to parts of the Southwestern U.S. and Mexico. The monsoon season is June 15 to September 30, though the actual arrival of the monsoon can vary.

Key Points

  • Over the past year, drought developed and intensified in the Four Corners region and southern California and Nevada, with the most intense drought conditions in Arizona and New Mexico.
  • The 2025 North American Monsoon began last week in parts of New Mexico and West Texas, bringing helpful rains to drought-stricken areas but also dangerous flooding. Other states (Arizona, Colorado, California, Nevada, Utah) await their first monsoonal precipitation.
  • Monsoonal rainfall only provides a fraction of the West’s water supplies, with the majority coming from snowpack. However, it can meaningfully reduce local drought impacts by reducing demand for water stored in reservoirs, recharging soil moisture and groundwater, benefitting agricultural production by improving grassland health for livestock and filling stock ponds, and reducing wildfire risk.
  • Outlooks favor above-normal monsoonal precipitation for the Southwestern U.S. in July. This could improve drought conditions and provide short-term relief, but dry landscape conditions leading into the monsoon mean drought is likely to persist. NOAAโ€™sย Climate Prediction Centerย predicts drought improvement (but not removal) for the area near the Arizona-New Mexico border in July.
  • However, precipitation in the first half of July is not a predictor of precipitation during the rest of the Monsoon season. Tracking conditions and outlooks as summer progresses will be especially important.ย 

This update is based on data available as ofย Monday, June 30, 2025 at 8:00 a.m. MT. We acknowledge that conditions are evolving.

What Is the North American Monsoon? Why Does It Matter?

  • Theย North American Monsoonย brings summer precipitation to parts of the Southwestern U.S. and Mexico, typically beginning in mid- to late June and lasting through September. This pattern results in active thunderstorms acrossย Arizona,ย New Mexico,ย Colorado, and southern/eastern Utah. Monsoonal surges can also occur outside of these “core” areas, reaching Nevada, southeastern California, Far West Texas, and Wyoming.
  • The North American Monsoon is a seasonal wind shift that occurs between June 15โ€“September 30, depending on geographic location. The monsoonal flow allows moisture to move into the Southwestern U.S., which provides a needed ingredient for thunderstorm activity.
  • The development of a ridge of persistent high pressure near the Four Corners region in the Southwest often initiates monsoon activity by providing a more moist, southerly flow from the subtropics around North America. Learn more aboutย monsoon dynamics.
  • The monsoon can vary in intensity and location from year to year. A more active monsoon season can moderate hot conditions with more thunderstorm activity, increase soil moisture, and reduce land surface temperatures, and improve drought conditions.ย 

How Does the Monsoon Impact Drought in the Southwest? 

  • Rainfall associated with the monsoon is very important for the Southwest U.S. Parts ofย Arizona and New Mexico receive as much as 10-60% of their annual precipitation during the monsoon season (data for June-August).
    • The position of the high pressure system can shift throughout the season, which determines if Arizona or New Mexico will get more or less rain. This can sometimes result in rapid drought improvement or onset.
  • A weak or inactive monsoon season can worsen short- and long-term drought conditions. For example, the inactiveย 2023 Monsoon Seasonresulted in significant drought expansion for New Mexico and Arizona. Meanwhile, an average to above-average monsoon can potentially improve or remove drought conditions, such as theย 2022 North American Monsoon, which was the 9th wettest on record and significantly improved drought conditions in Arizona and New Mexico.
  • The monsoon has a lesser influence in Nevada and California, though areas of southern Nevada and southeastern California occasionally receive significant monsoonal precipitation. On average, 20-25% of southern Nevadaโ€™s precipitation falls during the summer.
  • Even in states where an outsized portion of annual water supply is derived from snowpack, monsoonal rainfall can still meaningfully reduce local impacts. For example, monsoonal precipitation can reduce demand for water stored in reservoirs, recharge groundwater, benefit agricultural production by improving grassland health for livestock and filling stock ponds, and reduce wildfire risk.

What Is the Drought Status Going into the North American Monsoon?

  • As of June 24, every state in the Southwest (and California) is experiencing some level of drought (D1-D4), according to the U.S. Drought Monitor :
  • National Weather Service offices throughout the Southwest have issuedย drought information statementsย describing local drought conditions and impacts, including for:
  • In Arizona and New Mexico, drought conditions have expanded since summer 2024. Drought intensified and expanded northward and westward into southern Nevada and California due to a dry summer in 2024 followed by a dry fall and winter. Some areas (e.g., Arizona, southern California, and Nevada)ย saw slight improvement this spring, but drought persists.
  • Looking back 12 months to the start of the last monsoon (June 2024) until now (May 2025), Arizona experienced its 3rd driest and Nevada its 13th driest Juneโ€“May,ย ย going back 130 years. Some areas were worse at the county scale. Yuma and Maricopa counties in Arizona; Imperial County, California; and Clark County, Nevada experienced June-May periods in the top three driest on record.
  • Utah,ย New Mexico, and theย Navajo Nationย have already declared drought emergencies.ย

Will the North American Monsoon Be Active through September? What Does This Mean for Drought?

  • Seasonal forecasts of monsoon precipitation are largely based on continental or global-scale influences (e.g., sea surface temperature patterns), while actual rainfall totals for a given location are influenced by local-scale factors (e.g., local landscape, humidity, and temperatures), some of which can change quickly and over short distances. As a result, there is greater uncertainty in monsoonal precipitation forecasts for specific locations than when considering the Southwest region as a whole.
  • The Southwestern U.S. isย forecast to be wetter than normalย through at least mid- to late July. However, precipitation in the first half of July isย not a predictor of precipitation during the rest of the monsoon season.
  • For the 2025 Monsoon Season,ย NOAAโ€™s Climate Prediction Centerโ€™s seasonal outlooksย favor above-normal temperatures and equal chances of below-normal, normal, and above-normal precipitation across most of the Southwestern U.S.ย An โ€œequal chancesโ€ outlook does not necessarily mean normal, or average, rainfall can be expected. Rather, it implies that there is nothing in the climate system (including the El Nino-Southern Oscillation, which is currently neutral) that is pushing weather patterns toward one extreme or the other and any scenario is possible.
  • Droughtย is predicted to persist in much of the region over the next month and theย summer months, with potential drought improvements (but not removal) in the โ€œcoreโ€ monsoon region at the Arizona-New Mexico border.
  • Given these outlooks,ย wildfire risk is forecasted to beย near normalย for parts of the Southwest that normally have good summer precipitation from the monsoon.
  • For short-term forecasts, see theย Quantitative Precipitation Forecast (QPF)ย or your local National Weather Serviceย Weather Forecast Office.

Odds Favor Wet Start for the Monsoon through Mid- to Late July

Potential Impacts of North American Monsoon Precipitation for Drought

MonsoonImpactsBelow-Average PrecipitationNear-Average PrecipitationAbove-Average Precipitation
Impact on DroughtLong- and short-term drought in the region would worsen, potentially similar to what happened in summer 2023.Short-term drought improvement is possible.This could help improve long- and short-term drought in the Southwest, but the potential for hazardous flash flooding would increase.
Water StorageIncreased reservoir storage and groundwater depletion as municipal and agricultural demand increase during hot season.An average-to-above average monsoon can increase water storage and replenish stock ponds in parts of the region, but not by significant amounts.  Research has shown that summer precipitation is less efficient than winter precipitation at alleviating hydrologic drought. However, a more active monsoon reduces outdoor water demand, which has a positive impact on water supply.
Wildland FireElevated wildland fire potential to continue through summer.Fire potential to return to near normal for this time of year. Lightning can be a source for fire ignition.Fire potential to return to near normal for this time of year.

Potential drought impacts if the Southwest receives below-average, near-average, or above-average precipitation during the 2025 North American Monsoon Season.
