A crisis of the commons: The fraught legacy and magnetic promise underpinning public lands in the United States — Paul Anderson (AspenJournalism.org)

This 1774 map shows the North American continent when it was still an unknown and unexplored wilderness inhabited by Native Americans. The vast interior would be acquired by the United States through the 1803 Louisiana Purchase and numerous land grabs that pushed against what then seemed like a limitless cornucopia.

โ€œThe house of America is founded upon our land, and if we keep that whole, then the storm can rage, but the house will stand forever.โ€ โ€” President Lyndon B. Johnson

Editorโ€™s note: This story is part one of a three-part series examining the notion of public lands, both in the United States and in our region. Part one looks at the earliest expressions of the commons in territories that would become the United States. Parts two and three, which will run Sunday and Monday, look at the history and legacy of what is now the White River National Forest. 

In April, U.S. Sen. John Hickenlooper, D-Colo., held a public gathering in Eagle to discuss the future of public lands under the Trump Administration. Will Roush, director of Carbondale-based Wilderness Workshop, stated a chief concern: Not only should public lands be protected โ€” they must be maintained.

โ€œPart of this work to make sure that we protect our public lands is just to keep our public land,โ€ Roush said, as quoted in The Aspen Times on April 16. โ€œIf we can have a conversation about protecting public lands, then weโ€™re not having a conversation about selling public lands.โ€

Roushโ€™s reference was to the proposed sale of public lands that had been floated by Republican lawmakers as part of the budget reconciliation process. Hickenlooper said that any such large sales of public land would happen โ€œover my dead body.โ€ Since then, the sale of public lands advanced by Sen. Mike Lee, R-Utah, was removed from the Republicansโ€™ โ€œBig Beautiful Billโ€ due to pushback from bipartisan public lands advocates.

โ€œSome things just shouldnโ€™t be for sale,โ€ Hickenlooper said, โ€œand selling our public lands, which is one of the greatest assets we have as a country, is unthinkable. Selling broad tracks of BLM land or national forest, thatโ€™s unconscionable. So, yeah, Iโ€™ll do everything humanly possible to block that. And Iโ€™ve talked to enough Republican senators that I canโ€™t imagine thatโ€™s ever going to happen โ€” famous last words.โ€

Exploiting veterans for cheap land

The idea of selling off lands held in public trust throughout the United States is grounds for national reflection on the significance of these very lands. Collectively referred to as the commons, these public lands are defined, according to an artificial intelligence search, as โ€œthe cultural and natural resources accessible to all members of a society, including natural materials such as air, water and a habitable Earth.โ€ 

Historically, the privatization of land across the continental United States has been, in large part, a protracted scandal of greed, corruption, exploitation and opportunism. The foundation of what President Lyndon B. Johnson called the โ€œhouse of Americaโ€ is established upon countless examples of feckless manipulation, starting in the aftermath of the Revolutionary War that opened the doors to Americaโ€™s nascent continental empire.

Unable to pay Revolutionary War soldiers with cash in the fight against British domination, the necessarily frugal Continental Congress of this fledgling nation issued scrip, a cash substitute that could be redeemed with land grants on the expanding Western frontier. This complied with Thomas Jeffersonโ€™s vision of a landed citizenry โ€” so-called philosopher farmers โ€” who would furnish America with an independent, homespun, land-based community of engaged citizens able to guide the nation toward an enlightened future by โ€œpossessing a chosen country with room enough for our descendants to the thousandth and thousandth generation.โ€

But the plan went awry when cash-strapped veterans of the War of Independence traded their hard-earned scrip for pennies on the dollar to unscrupulous speculators who then cashed in the ill-gotten scrip to acquire millions of acres of Western land. These acts of greedy acquisition squandered the Jeffersonian promise of opening the country to those who had heroically served, often at great sacrifice. Land exploitation was condoned by those who would capitalize on the plight of veterans and the speculation of rising property values as the frontier moved west.

To retiring Gen. George Washington, this represented an irreparable moral failure to make good on a โ€œdebt of honor,โ€ which he warned of in his Letter to the Governors at the successful culmination of the Revolutionary War in 1783: โ€œIn what part of the continent shall we find any man or body of men who would not blush to stand up and propose measures purposely calculated to rob the soldier of his stipend? And were it possible that such a flagrant instance of injustice could ever happen, would it not excite the general indignation and tend to bring down upon the authors of such measures the aggravated vengeance of Heaven?โ€

It may be hard to imagine a time in American history when land was so egregiously exploited โ€” or that frontier land could be owned before it was even accurately measured. In โ€œThe Measuring of America,โ€ Andro Linklater described the evolution of the earliest measuring instruments necessary for assessing land values: โ€œMeasuring out the wilderness made it possible for someone to buy and own it. This was a revolutionary concept. For centuries, the land had been lived in by the Delaware and passed through by the Miami and occupied by the Iroquois, but no one had ever owned it. No one had ever even thought of owning it. The idea of one person owning land did not yet exist on the west bank of the Ohio.โ€

Puritan colonist John Winthrop of the Massachusetts Bay Company reported in the 1600s, โ€œAs for the natives of New England, they enclose no land.โ€ His reference to the enclosure echoed back to England in the 1100s when the public commons had been enclosed by the ruling aristocracy, banishing the people from their native landscapes. In America, where religious freedom had been a primary inspiration for colonial settlement in the new land, the acquisition of property soon predominated as a means for prosperity and personal gain.

Whereas Spanish and French New World settlements were owned strictly by the kings, the British colonies allowed individual ownership, which became a compelling reason for a dramatic swell in migration across the Atlantic. The resultant land hunger made a stark contrast to Native American concepts of the land as sacred common ground.

โ€œWhat is this you call property?โ€ asked a Massasoit chief in the 1620s of Plymouth colonists whom he had befriended. โ€œIt cannot be the earth, for the land is our mother, nourishing all her children, beasts, birds, fish and all men. The woods, the streams, everything on it belongs to everybody and is for the use of all of us. How can one man say it belongs only to him?โ€

A print published in 1866 by Currier & Ives in New York shows a native and three trappers seated around campfire, and three horses standing by a lake. Early white settlers, many driven across an ocean by a hunger to amass property, met with natives who in the words of one 17th century settler โ€œenclose no land.โ€ CREDIT: LIBRARY OF CONGRESS

Commoditizing the land

As land ownership evolved, the word โ€œpropertyโ€ had to be redefined to include land. That is why the Virginia Constitution of 1776 โ€” which was a prelude to the U.S. Constitution โ€” stated โ€œlife, liberty and propertyโ€ to be fundamental rights. The right to โ€œthe pursuit of happinessโ€ came in a later iteration. It was land that defined a legitimate human pursuit.

Jefferson, Americaโ€™s third president, assumed, according to Linklater, โ€œthe possession of land was the Newtonian principle that made democracy work. It guaranteed the independence of the individual and gave each one an interest in building a law-abiding community. All that was needed was education to teach them how best to use their freedom.โ€

James Madison, co-author of the Federalist Papers and the fourth president of the United States, differed with Jeffersonโ€™s land ethic. Madison regarded land ownership as restrictive and limiting to the need for a โ€œcommonsโ€ โ€” the joint ownership and stewardship of the land. โ€œWhenever there are uncultivated lands and unemployed poor,โ€ wrote Madison, โ€œit is clear that the laws of property violate natural right.โ€ In an echo of the Native American view, Madison concluded, โ€œThe earth is given as a common stock for man to labor and live on.โ€

As the land became a transactional commodity, it was no longer valued solely for its production potential, but was valued for the raw land itself and what it might bring in speculative appreciation. โ€œMore than in any other economy of the time,โ€ wrote Linklater, โ€œAmerican land was the prime producer of wealth โ€ฆ mostly from the increase in its value.โ€

Once a means of measuring the land was accomplished with a chain-link device called Gunterโ€™s Chain, named for its inventor, land could be more accurately quantified, with metes and bounds better determined. This facilitated ownership assurances that could be defended by law. Gunterโ€™s Chain preceded, by more than a century, the more widely used theodolite, a precise optical type of transit.

In the hands of savvy capitalists, measuring the land became a fever utilized by land corporations such as the Ohio Company, which used devalued currency that it had acquired to effect the most advantageous land purchases. โ€œIn the 1780s,โ€ wrote Linklater, โ€œmost [state currencies] could be bought on the street for twenty cents on the dollar. When the states began to put their own public lands on sale, the holders of such notes could use them to pay for land at the currencyโ€™s full value.โ€

Speculation rewarded those who held the land as it escalated in price commensurate with demand from, as Linklater describes, โ€œland-hungry, timber-yearning, field-dreaming squatters in Kentucky and Virginiaโ€ who sought land-owning opportunities. These opportunists saw the frontier as something more tangible than a romantic vision. โ€œThe adventure of taming the frontier was certainly there,โ€ wrote Linklater, โ€œbut what drew people from eastern states and from around the world was the desire of this soil magically transformed from wilderness to property by the act of measurement and mapping. โ€ฆ The ease with which it made land available to anyone who went west in search of it had an almost incalculable influence on the development of the American psyche and the American economy.โ€

Gunterโ€™s Chain was an early surveying tool of the late 1700s that became the first universally accepted measure for demarking western lands for acquisition and sale. Prior land measurements were vague, uncertain, non-conforming and readily challenged. CREDIT: LIBRARY OF CONGRESS

In his seminal 1782 essay, โ€œWhat Is an American?,โ€ French immigrant farmer Jean de Crevecoeur issued a paean to the land and what it meant to America then. โ€œI wish I could be acquainted with the feelings and thoughts which must agitate the heart and present themselves to the mind of an enlightened Englishman when he first lands on this continent. He must greatly rejoice that he lived at a time to see this fair country discovered and settled. He must necessarily feel a share of national pride when he views the chain of settlements which embellishes these extended shores.โ€

Equality and independence, wrote Crevecoeur, were the values the land gave to its new legal owners. โ€œWe are a people of cultivators, scattered over an immense territory, communicating with each other by means of good roads and navigable rivers, united by the silken bands of mild government, all respecting the laws without dreading their power, because they are equitable. โ€ฆ We are all animated with the spirit of an industry which is unfettered and unrestrained because each person works for himself.โ€

The American landscape became an asylum for the landless poor of Europe who had no opportunity to own land where they were born because of feudal controls that held the land for the aristocracy. โ€œCan a wretch who wanders about, who works and starves, whose life is a continual scene of sore affliction or pinching penury โ€” can that man call any other kingdom his country?โ€ asked Crevecoeur. โ€œA country that had no bread for him, whose fields procured him no harvest, who met with nothing but the frowns of the rich, the severity of the laws, with jails and punishments, who owned not a single foot of the extensive surface of this planet?โ€

Is it any wonder that land hunger was pervasive and drove hard men and women onto the rapidly expanding frontier of a continent that felt ripe for the plucking? Americaโ€™s first president was exuberant in his depiction of just this manner of thought when he wrote his Letter to the Governors in 1783, as the Revolutionary War came to an end.

โ€œThe citizens of America,โ€ Washington wrote, โ€œplaced in a most enviable condition, as the sole lords and proprietors of a vast tract of continent, comprehending all the various soils and climates of the world and abounding with all the necessaries and conveniences of life, are now, by the late satisfactory pacification, acknowledged to be possessed of absolute freedom and independency, are to be considered as the actors on a most conspicuous theatre which seems to be peculiarly designated by Providence for the display of human greatness and felicity.โ€

Manifest Destiny was a phrase coined by John Oโ€™Sullivan that stated: โ€œThe right of our manifest destiny to overspread and to possess the whole of the continent which Providence has given us for the development of the great experiment of liberty and federated self-government entrusted to us.โ€ The associated image, โ€œAmerican Progress,โ€ was painted by in 1872 by John Gast, a Prussian-born painter, printer, and lithographer who lived and worked during the 1870s in Brooklyn.

Manifest Destiny

Such effulgent prose prompted John Oโ€™Sullivan to declare, a century later, โ€œManifest Destinyโ€ as the divine right of America to possess an entire continent as its just reward without moral scrutiny or remorse, but simply as a preordained right through the grace of God and the happenstance of history.

โ€œOur Manifest Destiny is to overspread and to possess the whole of the continent which Providence has given us for the development of the great experiment of liberty and federated self-government entrusted to us,โ€ Oโ€™Sullivan, a noted editor and diplomat, wrote in an 1845 essay about annexing vast areas of Western U.S. lands, including Texas.

This utilitarian affirmation of a right to possess paved the way to exploit all that the land could provide in a sometimes misbegotten destiny that would include the Dust Bowl of the 1930s. Manifest Destiny became a national entitlement of unlimited scope that remains an imperialistic rationale today.

Although individual and corporate land acquisitions of the 1700s ceded control of millions of acres from the public trust to private holdings, they were small potatoes compared with national acquisitions such as the Louisiana Purchase in 1803 as governments entered into the land market with astronomical acreages that amalgamated landscapes as mere abstractions.

โ€œThe sale of an empire,โ€ wrote Linklater of Jeffersonโ€™s enormous real estate deal with the French, โ€œwas not an issue; it was simply a land deal.โ€ The now-seemingly paltry sum of $15 million was deemed high at the time and raised eyebrows for profligacy. Yet, the French holdings of the purchase were acquired for 5 cents per acre โ€” one of the most astounding real estate deals in history.

In Steven Ambroseโ€™s โ€œUndaunted Courageโ€ account of Meriwether Lewis and William Clarkโ€™s Corps of Discovery, the extent of the newly acquired Western lands and a constant sense of the unknown in their vast scale affected every member of the team and its captains. After reaching the Pacific coast at the mouth of the Columbia River, Lewis and Clark called for a vote that would decide a conundrum as to where the Corps would winter over. That vote was the first time in an official U.S. government capacity that a woman, a Native American and a Black African cast ballots with equal weight to their white counterparts. Sacajawea filled two roles, as both a woman and a Native American; and Clarkโ€™s slave, York, was the Black man. The captains granted them a say because their shared travails during the 18 months it took to reach the coast across the wilderness of the Louisiana Purchase had bonded them as equals.

And yet, what of the natives who had no vote and no say at other crossroads? They became collateral damage in the rapaciously acquisitive westward march across their former homelands. โ€œAlmost every Indian war from Fallen Timbers in 1794 to the final massacre at Wounded Knee in 1890 had its origin in the hunger for land,โ€ wrote Linklater. Defeated, coerced and compromised, the natives often had no choice but to sign land-granting treaties that exploited their plight under rule by opportunistic whites. โ€œThe United States was making an offer that could not be refused,โ€ wrote Linklater.

The treatment of the Cherokee was among the most brutal when settlement pressures divided their nation and later expelled its Eastern half, even though the tribe had settled to legitimately tend the land with white manโ€™s ways, as had been stipulated. Removed by force to Oklahoma in the winter of 1838 by edict of President Andrew Jackson, the Trail of Tears claimed the lives of 4,000 of the dispossessed 16,000 from disease, starvation and bitter cold on this notorious death march.

His calloused treatment of the Cherokees in shameless pursuit of land reflected a deeper set of character flaws regarding Jacksonโ€™s presidency (1829-37), flaws that appear to crop up now and again in Americaโ€™s top political figures, as a newspaper editorial of the day made clear:

“The language of Jackson has been that of a heartless despot, solely occupied with the preservation of his own authority. Ambition is his crime, and it will be his punishment too: intrigue is his native element, and intrigue will confound his tricks, and will deprive him of his power; he governs by means of corruption, and his immoral practices will redound to his shame and confusion. His conduct in the political arena has been that of a shameless and lawless gamester. He succeeded at the time, but the hour of retribution approaches, and he will be obliged to disgorge his winnings, to throw aside his false dice, and to end his days in some retirement, where he may curse his madness at his leisure; for repentance is a virtue with which his heart is likely to remain forever unacquainted.”

This treaty-breaking policy became a pattern that repeated itself again and again as Linklater describes: โ€œIncursion by small groups of settlers, growing tension, Indian violence, American retaliation and the intervention of the U.S. Army.โ€

Such would be the fate of the Northern Utes in 1881, when this same progression fomented what was known as the Meeker Massacre and the expulsion of the Utes to two reservations after Colorado Gov. Frederick Pitkinโ€™s decree that โ€œThe Utes must go!โ€ Pitkin proclaimed that the โ€œUte problemโ€ would be resolved either by moving them to reservations or eliminating them by extermination. Thus, 12 million acres of land, including Aspen and the Roaring Fork Valley, were opened to white settlement.

Love of the land

As egregious as this historical progression sounds, all of us in western Colorado now call Ute lands our home. And so it has gone for generations of Americans whose acquisition of these once Native American lands has been a blessing overlaying a curse to those who were ruthlessly dispossessed. Many an author has described with rapture a sense of discovery, enchantment and enrichment from contact with these fought-over lands from which whole peoples were vanquished.

โ€œWhen I strike the open plains, something happens,โ€ wrote author Willa Cather (1873-1947), whose writings exude a deep appreciation for the Western landscapes of America. โ€œIโ€™m home. I breathe differently. That love of great spaces, of rolling open country like the sea, itโ€™s the grand passion of my life.โ€

In 1850, long before Cather found her identity with the land, an Oregon Trail pioneer from Indiana, Margaret Frink, wrote a florid description of a junction of Midwestern wagon routes upon crossing Cottonwood Creek in Nebraska. Her praises as a witness to history are quoted in Rinker Buckโ€™s โ€œThe Oregon Trailโ€:

“In the afternoon we came to the junction of the emigrant road from St. Joseph with our road. โ€ฆ Both roads were thickly crowded with emigrants. It was a grand spectacle to view the vast migration slowly winding its way westward over the broad plain. The country was so level we could see the long trains of white-topped wagons for many miles. It seemed to me that I had never seen so many human beings in all my life.”

Buck, who traveled the 2,150-mile Oregon Trail in four months by mule-drawn wagon in 2011, also quoted journalist George Law Curry, who crossed the trail in 1846 and was among 400,000 who had done so in the 15 years before the Civil War. Curryโ€™s reflection was published in a St. Louis newspaper:

โ€œLife on the plains far surpasses my expectation; there is a freedom and a nobleness about it that tend to bring forth the full manhood. A man upon the horizon-bound prairie feels his own strength and estimates his own weaknesses. He is alive to everything around him. For him there is a joy in the โ€˜lone elmโ€™ grandeur on the mounds, beauty in the grassy and flower-besprinkled couch on which he rests, and a glory forever round him that stretches his spirit to its fullest tension.โ€

There were other reasons for the migration that made the West attractive, such as the growth of industrializing cities and the impending conflict over the spread of slavery, both repellant to those sensitive, bucolic souls seeking a peaceful little spread far from the madding crowd. The 1862 Homestead Act was the inducement where 160 acres could be claimed, worked and owned outright after living on it and improving it for five years. A small filing fee was required, as well as enough savings to get through until the land proved up.

โ€œThe idea behind the Homestead Act,โ€ wrote Ian Frazer in โ€œGreat Plains,โ€ โ€œwas that a nation of small, independent farmers would make the best foundation for democracy. It was an idea as old as the United States where politicians from the North wanted to fill the West with farmers to stop the spread of slavery.โ€

There was a political motive for offering free land, and an economic motive for those who sought it. Yet, the gift of land was not always fruitful for those who acquired it because of what all real estate brokers know about location, location, location. Bottomland near railroads was hard to get, so most homesteads were located on less-than-optimal plots. The homestead promise often failed to match up to the reality on the ground on what was a minimal portion of land, which rarely was enough to subsist on in pursuit of the evasive and intangible American dream.

Frazer wrote that the invention of barbed wire was necessary for any farm settlements to be possible and that the rates of success were marginalized by climate and aridity. Promotions by the U.S. Geological Survey and the serving railroads attempted to whitewash this harsh reality with โ€œthe meteorological theory that โ€˜rain follows the plowโ€™ โ€ฆ that cultivation of the soil, human activity, steam from railroad engines โ€” all the developments that accompany settlement โ€” produced increased rainfall.โ€ A so-called โ€œrainlineโ€ was declared as an enticement by the Santa Fe Railroad to advance frontier settlements by 18 miles per year across the naturally arid West.

Cultivation was also thought to enhance dryland agriculture, but it proved yet another frontier fallacy as the sod was broken by the steel plow, resulting in destructive erosion. โ€œMany thousands of homesteaders ended up owning farms on the Great Plains,โ€ wrote Frazer. โ€œBut an even larger number went broke, lost their crops to grasshoppers, saw their fields dry up and blow away, went into debt, went crazy with loneliness, sold out, left, and never came back.โ€

Still, a deep-seated affection and affinity existed for the land as a romantic sense of place that was captured in verse by Katherine Lee Bates when she wrote โ€œAmerica the Beautifulโ€ in 1895, five years after the closing of the American frontier. Her inspiration was a vision of Coloradoโ€™s Pikes Peak, for which the song was originally named:

O beautiful for spacious skies,ย 
For amber waves of grain,ย 
For purple mountain majestiesย 
Above the fruited plain!ย 
America! America!ย 
God shed his grace on theeย 
And crown thy good with brotherhoodย 
From sea to shining sea!

Settlers in the Roaring Fork Valley, specifically Missouri Heights, raised similar paeans to the blessings of the land they acquired in the late 1800s and early 1900s as described by settler David Kapp in Anita McCune Wittโ€™s โ€œThey Came From Missouri: The History of Missouri Heights, Coloradoโ€:

Iโ€™ve got a hundred-sixty acres in the valley
Iโ€™ve got a hundred-sixty acres of the best
Got an old stove there
Thatโ€™ll cook three square
And a bunk where I can lay me down to rest.
Iโ€™ve got a hundred-sixty acres full of sunshine
Iโ€™ve got a hundred-sixty million stars above
Got an old paint hoss
Iโ€™m the guy whoโ€™s boss
On a hundred-sixty acres that I love.

Witt wrote: โ€œThey came by ship, by foot, by horse, and mule and oxen, by covered wagon and railroad box car, from all over the world, ultimately to settle on the high mesa above the Roaring Fork Valley.โ€

The land forged the America character

The frontier experience was best described by Frederick Jackson Turner in his famous 1893 essay, โ€œThe Significance of the Frontier in American History.โ€ In that vaunted text, Turner credits the varied landscapes of the American frontier with deeply influencing the American character.

โ€œThe existence of an area of free land, its continuous recession, and the advance of American settlement westward explain American development,โ€ wrote Turner. โ€œBehind institutions, behind constitutional forms and modifications lie the vital forces that call these organs into life and shape them to meet changing conditions. โ€ฆ The changes involved in crossing a continent, in winning a wilderness, and in developing at each area of this progress out of the primitive economic and political conditions of the frontier into the complexity of city life.โ€

Turnerโ€™s thesis underscores the critical importance of the land โ€” the commons โ€” as a formative influence to national characteristics of individualism, risk-taking, innovation and the constant refreshing of democratic institutions on the ever-advancing frontier as manifest in new communities far beyond the reach of established institutions. Against that demanding, sometimes fatal, character-building crucible, the American spirit was forged.

โ€œAmerican social development has been continually beginning over again on the frontier,โ€ wrote Turner. โ€œThis perennial rebirth, this fluidity of American life, this expansion westward with its new opportunities, its continuous touch with the simplicity of primitive society, furnish the forces dominating the American character. The true point of view in the history of this nation is not the Atlantic Coast, it is the Great West.โ€

Turner described a de facto evolution across the landscape: First came the pioneer, who provisioned himself from the land with the rudiments of shelter, food and clothing, but never ownership. As the pioneers moved to new ground, they were replaced by emigrants who sought a longer tenure with land ownership, farming and establishing more permanence with their dwellings through the social institutions that platted towns and birthed cities. Finally came the developers, mercantile agents and entrepreneurs who converted the land to commercial purposes and ushered in urbanity.

The frontier landscapes also played a role in social diversity, as Turner posited: โ€œIn the crucible of the frontier the immigrants were Americanized, liberated and fused into a mixed race.โ€ The frontier also influenced politics: โ€œThe legislation which most developed the powers of the national government, and played the largest part in its activity, was conditioned on the frontier.โ€ The frontier also set a tone for a particular American personality: โ€œThe American intellect owes its striking characteristics to the frontier,โ€ wrote Turner, โ€œthat coarseness and strength combined with acuteness and inquisitiveness, that practical, inventive turn of mind, quick to find expedients, that masterful grasp of material things, lacking in the artistic but powerful to effect great ends, that restless, nervous energy, that dominant individualism, working for good or for evil, and withal that buoyancy and exuberance which comes with freedom โ€” these are the traits of the frontier.โ€

Author Wallace Stegner recognized that the frontier had mostly been a wilderness bereft of human influence, which attributed the frontier with the power to โ€œshape our history as a people.โ€ Wilderness, the most protected landscape of U.S. public lands, was changed by those who pushed against it while they, too, were changed by coming in contact with it.

โ€œWhile we were demonstrating ourselves the most efficient and ruthless environment-busters in history,โ€ wrote Stegner, โ€œand slashing and burning and cutting our way through a wilderness continent, the wilderness was working on us. It remains in us as surely as Indian names remain on the land.โ€ Americans, he added, were โ€œin subdued ways, subdued by what we conquered,โ€ making us a nation of โ€œcivilized man who has renewed himself in the wild.โ€

Our wild lands โ€” the untamed commons โ€” continue to provide โ€œspiritual refreshment,โ€ wrote Stegner, โ€œwhere the fun houses, the bulldozers, and the pavement of our civilization are shut out.โ€ Stegner quoted author Sherwood Anderson, who suggested that men working in the outdoors โ€œgot a sense of bigness outside themselves that has now in some way been lost. Mystery whispered in the grass, played in the branches of trees overhead, was caught up and blown across the American line in clouds of dust at evening on the prairies.โ€ Available here was  a โ€œdeep, semi-religious influenceโ€ where men lost their โ€œshrillnessโ€ and โ€œlearned the trick of quiet.โ€

Within his inspiring essay on wilderness, written in 1960 as a letter of comment to a federal lands manager, Stegner offered a manifesto for the conservation of a landscape that exists thanks to enlightened visionaries who recognized its lasting value for future generations, a landscape that can never be re-created:

โ€œSomething will have gone out of us as a people if we ever let the remaining wilderness be destroyed; if we permit the last virgin forests to be turned into comic books and plastic cigarette cases; if we drive the few remaining members of the wild species into zoos or to extinction; if we pollute the last clear air and dirty the last clean streams and push our paved roads through the last of the silence, so that never again will Americans be free in their own country from the noise, the exhausts, the stinks of human and automotive waste. And so that never again can we have the chance to see ourselves single, separate, vertical and individual in the world, part of the environment of trees and rocks and soil, brother to the other animals, part of the natural world and competent to belong in it.

โ€œWithout any remaining wilderness we are committed wholly, without chance for even momentary reflection and rest, to a headlong drive into our technological termite-life, the Brave New World of a completely man-controlled environment. We need wilderness preserved โ€” as much of it as is still left, and as many kinds โ€” because it was the challenge against which our character as a people was formed. The reminder and the reassurance that it is still there is good for our spiritual health even if we never once in 10 years set foot in it. It is good for us when we are young, because of the incomparable sanity it can bring briefly, as vacation and rest, into our insane lives. It is important to us when we are old simply because it is there โ€” important, that is, simply as an idea.โ€

Wilderness historian Roderick Nash detailed the evolution of wilderness ideology in his 1965 book โ€œWilderness and the American Mind,โ€ quoting Aldo Leopold, Americaโ€™s first conservation biologist: โ€œRecreational development is a job not of building roads into lovely country,โ€ Leopold observed in 1938, โ€œbut of building receptivity into the still unlovely human mind,โ€ which lacked, in Leopoldโ€™s view, the wherewithal to โ€œembrace, love, respect and admire the land.โ€

Still, the utilitarian counterpoint has played a strong hand in land management and was made clear when vast acreages in Alaska were earmarked for wilderness during some of the most passionate conservation years in American history in the 1970s as the nation awoke to emergent wilderness values. โ€œI believe,โ€ said Robert Dilger of the Washington State Construction Trades Council, โ€œthat it is unwise to lock up for the future 146 million acres of land that has hardly been surveyed, let alone thoroughly analyzed for its resources.โ€

Dilgerโ€™s views echoed the โ€œWise Useโ€ mindset that swept through many Western states in the 1980s and โ€˜90s, an idea that originated with Gifford Pinchot (1865-1946), the first chief of the U.S. Forest Service under President Theodore Roosevelt. โ€œPinchotโ€™s devotion to the forest,โ€ states a Facebook site honoring Pinchot, โ€œwent far beyond beauty and spiritual admiration. He saw protecting the national parks as a โ€˜social goodโ€™ and recognized that national forests had value not only because of their beauty but also because of the resources they provided to citizens.โ€

The outcome of innumerable debates, contentions and often-conflicting policies over public lands has resulted in a cumulative de facto division of enormous reaches of the commons across the continent. In a little over a century, the parceling of the great American landscape represents an intractable set of manipulations to control and own the commons by those who have often sought none other than personal gain. 

Linklater wrote: โ€œSince 1785 the landmass of the United States has grown to 2.3 billion acres, and of that total, 1.8 billion acres spread across 32 states have been at one time in the public domain. More than 1 billion acres have been transferred to individual ownership. In economic terms alone, it has represented the greatest orderly transfer of public resources to the private sector in history.โ€

Given the current trends in Washington, D.C., the proposed dispersal of public lands to which Hickenlooper speaks may surge again in historic proportions in acts that may make a strange mockery of a traditional and well-known Woody Guthrie song that has a crucial meaning to most Americans.

โ€œThis Land is Your Landโ€

This land is your land, this land is my land 
From California to the New York Island 
From the Redwood forest to the Gulf Stream waters 
This land was made for you and me. 

As I went walking that ribbon of highway 
I saw above me that endless skyway 
I saw below me that golden valley 
This land was made for you and me. 

I roamed and I rambled and I followed my footsteps 
To the sparkling sands of her diamond deserts 
While all around me a voice was sounding 
This land was made for you and me. 

When the sun came shining, and I was strolling 
And the wheat fields waving and the dust clouds rolling 
A voice was chanting as the fog was lifting, 
This land was made for you and me. 

This land is your land, this land is my land 
From California to the New York Island 
From the Redwood Forest to the Gulf Stream waters 
This land was made for you and me.

Temperature

NOAA’s National Centers for Environmental Information calculates the global temperature anomaly every month based on preliminary data generated from authoritative datasets of temperature observations from around the globe. The major dataset,NOAAGlobalTemp version 6.0.0, uses comprehensive data collections of increased global area coverage over both land and oceansurfaces. NOAAGlobalTempv6.0.0 is a reconstructed dataset, meaning that the entire period of record is recalculated each month with new data. Based on those new calculations, the new historical data can bring about updates to previously reported values. These factors, together, mean that calculations from the past may be superseded by the most recent data and can affect the numbers reported in the monthly climate reports. The most current reconstruction analysis is always considered the most representative and precise of the climate system, and it is publicly available through Climate at a Glance.


July 2025

July 2025 recorded a global surface temperature 1.00ยฐC (1.80ยฐF) higher than the 20th-century average, making it the third-warmest July since records began in 1850. Only July of 2024 (warmest) and July 2023 were warmer. All ten warmest Julys on record have occurred since 2016. July 2025 also marks the 49th consecutive July with above-average global temperatures.

The global ocean-only surface temperature for July was the third-highest on record, at 0.92ยฐC (1.66ยฐF) above average. This was cooler than July 2023 (warmest) and July 2024. For land areas, the global land-only surface temperature in July tied as the seventh-warmest on record, at 1.20ยฐC (2.16ยฐF) higher than the 20th-century average. This was the smallest July land temperature anomaly since 2019 and the smallest for any month since December 2022 (+1.16ยฐC / +2.09ยฐF).

smoothed map of blended land and sea surface temperature anomalies is also available.

In July 2025, most of the globe experienced much-warmer-than-average temperatures. The most significant high temperature anomalies, exceeding 1.0ยฐC (1.8ยฐF) above average, occurred over Europe, southern Asia, the northern Pacific Ocean, and parts of North and South America, central-western Antarctica, and the North Atlantic Ocean. Record-high July temperatures were limited to areas within southern and eastern Asia, the Arctic region, the western and southern Pacific Ocean, and parts of the Southern Ocean. Overall, record-high July temperatures were observed across close to 6% of the Earth’s surface.

In contrast, parts of northern North America, the North Atlantic, India, and western and eastern Antarctica had cooler-than-average conditions during July 2025. Notably, no land or ocean areas recorded record-cold July temperatures.

Regionally, Asia and Europe (tied) had their fourth-warmest July on record. The Arctic region, Africa, and the Caribbean region had their seventh-warmest, eighth-warmest, and ninth-warmest (tied) July on record, respectively. North America, South America, Oceania, and the Hawaiian region all had above-average July temperatures, though none ranked among their ten warmest Julys on record. Contrasting with other regions, the Antarctic region had a slightly below-average July temperature departure of -0.02ยฐC (-0.04ยฐF). This was the coldest July for the region since 2016.

July temperature summaries provided by national meteorological services and media reports include:

  • The average temperature in theย United Kingdom (U.K.)ย for July 2025 was 16.8ยฐC (62.2ยฐF), which is 1.5ยฐC (2.7ยฐF) above average. This ranked as the nation’s fifth-warmest July on record. Minimum (nighttime) temperatures were notably high, with the U.K. experiencing its second-warmest July on record for minimum temperatures, according to the Met Office.
  • Irelandย experienced its ninth-warmest July on record, and the 12th-warmest month overall in 126 years of record-keeping. The temperature was 1.21ยฐC (2.18ยฐF) above the 1991โ€“2020 average. Notably, Ireland’s five warmest Julys have all occurred since 2001.
  • In July 2025, theย Kingdom of Bahrainย recorded an average temperature of 36.1ยฐC (97.0ยฐF). This temperature was 1.0ยฐC (1.8ยฐF) above the monthly average and was the sixth-highest July mean temperature since national records began in 1902. Additionally, it was reported that Bahrain experienced 18 days in July where maximum temperatures surpassed 40ยฐC (104ยฐF).
  • Australiaย recorded an above-average national temperature in July, at 0.60ยฐC (1.08ยฐF) above normal. However, this did not place it among the ten warmest Julys on record for the country. All of Australia’s states experienced above-average mean temperatures for July. Western Australia’s mean temperature, at 0.07ยฐC (0.13ยฐF) above average, was the lowest since 2016.
  • Most ofย New Zealandย experienced above-average temperatures during July 2025, resulting in a national average temperature of 9.2ยฐC (48.6ยฐF), or 1.1ยฐC (2.0ยฐF) above average. This was New Zealand’s fourth-warmest July since national records began in 1909. Nine locations had their warmest July on record.
  • Japan experienced an intense heat wave in July, with maximum temperatures above 35ยฐC (95ยฐF). July 30 became Japan’s hottest day on record with maximum temperatures reaching 41.2ยฐC (106.2ยฐF) in Tamba, Hyลgo Prefecture (Central Japan). This surpassed the previous record from 2018 and 2020 by a narrow margin of 0.1ยฐC (0.2ยฐF). Heat stroke alerts were reportedly issued for 33 of Japan’s 47 prefectures. As a result of the heat, more than 10,800 people were hospitalized with heat-related illnesses. Additionally, July 2025 wasย Japan’sย warmest July on record, with temperatures averaging 2.89ยฐC (5.20ยฐF) above normal. This surpassed the previous record, set in 2024, by 0.73ยฐC (1.31ยฐF). The past three years (2023, 2024, and 2025) are all among Japan’s five warmest years on record.
  • South Korea experienced a significant heat wave in mid to late July, leading to record-breaking temperatures. Notably, Seoul recorded a new high of 22 tropical nights (minimum temperatures above 25ยฐC / 77ยฐF), surpassing the 1994 record of 21 since records began in 1907. One of these nights saw a record-breaking low of 29.3ยฐC (84.7ยฐF), marking the hottest July night on record. Media reports indicated the extreme heat caused record power demand.
  • Persistent above-average temperatures affected Greece and Turkey from mid- to late July. Temperatures consistently exceeded 35ยฐC (95ยฐF), with some weather stations recording over 40ยฐC (104ยฐF). In Greece, popular tourist attractions were closed due to lingering extreme temperatures. On July 25, a new all-time national maximum temperature record for Turkey was set in Silopi, reaching 50.5ยฐC (122.9ยฐF). This shattered the previous record from August 2023 by 1.0ยฐC (1.8ยฐF) and marked the first time a temperature of 50ยฐC (122ยฐF) was recorded in Turkey. The extreme heat and drought conditions contributed to the development of dangerous wildfires across the region.

Year-to-date Temperature: Januaryโ€“July 2025

The global surface temperature for Januaryโ€“July 2025 was the second-highest in NOAA’s 176-year record, at 1.18ยฐC (2.12ยฐF) above the 20th-century average. This is just 0.10ยฐC (0.18ยฐF) shy of tying the record set from Januaryโ€“July 2024. A statistical analysis by NCEI scientists indicates a very high likelihood (greater than 99% chance) that the year 2025 will be among the five warmest years on record, with less than a 1% chance of being the warmest year on record.

Separately, both the global land-only and global ocean-only temperatures for Januaryโ€“July were the second warmest on record. For both, only Januaryโ€“July of 2024 was warmer.

smoothed map of blended land and sea surface temperature anomalies is also available.

During Januaryโ€“July 2025, warmer-than-average temperatures were prevalent across much of the Earth’s land and ocean surfaces. The most significant high-temperature anomalies, 1.5ยฐC (2.7ยฐF) above average or higher, were observed in the Arctic region, northern North America, much of Asia, and western and eastern parts of Antarctica. Record-high temperatures for the Januaryโ€“July period were observed in western Europe, the British Isles and the surrounding North Atlantic Ocean, across parts of the Arctic and western Antarctic regions, southern Asia, southwestern and southern Australia, the western and central Pacific Ocean, and the Indian Ocean.

In contrast, based on the percentiles map, cooler-than-average temperatures during this seven-month period were largely confined to central and eastern Antarctica. However, no land or ocean areas experienced record-cold temperatures during Januaryโ€“July.

During Januaryโ€“July 2025, several regions saw notably high temperatures. Europe, Asia, Oceania, and the Arctic region each recorded their second-warmest Januaryโ€“July period on record. Africa and the Caribbean region had their fourth-warmest, the Hawaiian region its fifth-warmest, and North America’s year-to-date temperature tied as the sixth-warmest on record. South America’s year-to-date temperature tied as the seventh-warmest on record. Although the Antarctic region had an above-average Januaryโ€“July temperature, it did not rank among its ten warmest on record.


Precipitation

Precipitation data from the Global Historical Climatology Network (GHCN)-Monthly are augmented by data with greater spatial coverage from the Global Precipitation Climatology Project (GPCP).

July 2025

As is typical, precipitation patterns varied globally during July 2025. Drier-than-average conditions were observed across the western, southeastern parts of the contiguous U.S., Alaska and Hawaii, southern Mexico, southern Europe, central parts of Australia, and across parts of western and central Asia. Eastern Asia, however, experienced contrast in precipitation totals, with some locations along the eastern coast and the northeast receiving more than double the monthly average precipitation. Wetter-than-average July conditions were also observed across the northern and northeastern contiguous U.S., northern Mexico, the British Isles, central and northeastern Europe, central and southeastern Russia, and across northeastern and southeastern Asia.

July precipitation summaries provided by national meteorological services and media reports include the following:

  • Precipitation varied acrossย Australiaย in July; however, the nation as a whole experienced a slightly wetter-than-average month. Regional differences were notable: Queensland, Tasmania, and the Northern Territory had drier-than-average conditions, while New South Wales, Victoria, and South Australia had wetter-than-average conditions. According to Australia’s Bureau of Meteorology, South Australia recorded its wettest July since 1998, and New South Wales and Victoria had their wettest July since 2010 and 2016, respectively.
  • On July 6, Typhoon Danas, an equivalent Category 3 typhoon, made landfall on Taiwan’s central-western coast. This was reportedly the first typhoon to make landfall in Chiayi County in nearly 120 years. Danas brought heavy rainfall to affected areas, including southern Taiwan, where rainfall totals reached 500โ€“600 mm (20โ€“24 inches). The torrential rain caused rivers, including the Gangkou River, to overflow their banks, leading to flash floods that submerged homes, roads, and farmlands, and damaged infrastructure. The storm also disrupted power, water, and communication services.
  • During mid- to late July, thunderstorms brought heavy rain and flooding to parts of the United Kingdom (U.K.). Several locations in Northern Ireland experienced their wettest July day on record; notably, Killowen received 69 mm (2.7 inches) and Murlough received 61 mm (2.4 inches) on a single day. Across England, Wales, Scotland, and Northern Ireland, the floods caused major property damage and transportation disruption.
  • The state of Jalisco, Mexico, was affected by heavy rain and flash floods during July 14โ€“18. Reports stated that over 100 homes were damaged.
  • From July 16โ€“21, heavy rain caused devastating floods and deadly landslides across southern regions ofย South Korea. During this six-day period, affected areas reportedly received 600โ€“800 mm (24โ€“31 inches) of rain, setting numerous records. More than 10,000 residents evacuated their homes. The floods submerged roads and farmland, damaged or destroyed thousands of homes and buildings, and resulted in the loss of approximately 1.5 million livestock. At least 19 people died, with the death toll expected to rise.
  • Torrential rain from severe thunderstorms affected parts of northern and central France during July 23โ€“24. Notably, Bohain-en-Vermandois, Aisne, in northern France received nearly a month’s worth of rain (70โ€“80 mm / about 3 inches) in just one hour on July 23. This intense rainfall caused floodwater to rise rapidly, inundating homes and streets and damaging infrastructure.
  • China experienced several heavy rainfall events during July 2025. These events included:
    • Remnants of Typhoon Dana, in combination with the East Asian monsoon, brought heavy rain to parts of southern and eastern China on July 10, according to reports. This resulted in floods, affecting approximately 10,000 people in Sichuan and Yunnan provinces. Reports indicated that 25 rivers exceeded alarming levels, with the Chishui River in Guizhou province reaching its highest recorded level since 1953 and the Xiaocao River reaching a 29-year high. One county in Yunnan province had 227.8 mm (9.0 inches) of rain fall in a 24-hour period โ€” the highest single-day total since 1958. In addition to floods, the intense rainfall triggered landslides, leading to evacuations and property damage.
    • Typhoon Wipha made landfall in Guangdong province, southern China, on July 20 as an equivalent Category 1 storm. It weakened as it moved southwest and made landfall in northern Vietnam on July 22 as a tropical storm. Wipha brought heavy rain and strong winds to the affected areas, resulting in uprooted trees, power outages, disrupted travel, damaged infrastructure, and in some instances, triggering landslides.
    • Storms brought nearly a year’s worth of rainfallโ€”about 449 mm (17.7 inches)โ€”to Baoding City in northern China within a 24-hour period (July 24โ€“25). Reports indicate that Baoding’s annual average precipitation is slightly over 500 mm (19.7 inches). The torrential rain triggered flash floods, caused power outages, and damaged bridges and roads. Over 19,000 people were evacuated from the affected regions.
    • In late July, strong storms brought torrential rain and catastrophic flooding to Beijing and neighboring provinces, affecting over 300,000 people. Beijing’s Miyun district was hard hit, receiving nearly a year’s worth of rain in just a few days. This caused rivers to overflow and resulted in deadly flash floods, which tragically killed at least 31 people at an Elderly Care Center. Reports indicate the Miyun Reservoir reached its highest level since 1959. The floodwaters also damaged roads and infrastructure, disrupting power and communication services.

August 6, 2025

Most of the Intermountain West is in a drought, with nearly 20 percent of the region stuck in the most severe, driest conditions, according to a Tuesday presentation from Colorado state climatologist Russ Schumacher and the National Oceanic and Atmospheric Administration…The most drought-stricken areas are west of the continental divide โ€“ a scraggly arc of mountain ranges where precipitation eventually drains westward, towards the Pacific Ocean.ย  The driest conditions in Colorado are largely concentrated on the Western Slope, while much of the Eastern Plains faces little to no drought, and has seen average or above-average precipitation levels since October…in April, abnormallyย hot and dry conditions rapidly melted snowpackย and began dumpingย  less precipitation than average across the West. Southern Arizona is even seeing some of its driest conditions over the last 130 years, according toย data prepared by the Colorado Climate Center.ย  Climate change is alsoย accelerating extreme heat conditionsย for the region, which could prolong future droughts. Denver, for instance, is projected to experience 32 days of extreme heat by 2050, compared to just four days on average between 1976-2005,ย according to NOAA data.ย

August 9, 2025

Colorado state climatologist says the weather has been hot and the monsoon season weak, with little signs of relief anytime soon

Drought conditions are getting worse on Coloradoโ€™s Western Slope, increasing the risk of wildfires, even as several large fires are already burning, scorching thousands of acres and forcing evacuations. Colorado State Climatologist Russ Schumacher said the extended dry period on the Western Slope contains โ€œechoesโ€ of the climate patterns in 2020, the worst wildfire season in Colorado history, when the three largest wildfires recorded in the state occurred…Like 2020, this summer has been hot, with above-average temperatures across much of the Western Slope, Schumacher said. The monsoon season has also been lackluster, with little precipitation and hot, dry weather coming on the heels of a winter with a poor snowpack. This June and July were among the 10 hottest on record in the northwestern corner of the state, where some of the largest wildfires are now raging, according to the Colorado Climate Center at Colorado State University. While the southern mountains got above-average precipitation in June, things remained dry in the northwest, where precipitation was less than 50% of average. In July, precipitation was below-average across the entire Western Slope…Extreme drought is now impacting all of Moffat, Rio Blanco, Garfield, Pitkin, Teller and Delta counties and part of Eagle County, according to the U.S. Drought Monitor. Severe drought has spread east into Summit, Routt and Lake counties and across the southwestern part of the state…

Lightning has sparked several wildfires in Colorado, including wildfires burning in the northwest near Meeker, in the southwest near Gatewayand in the Black Canyon of the Gunnison National Park, according to InciWeb.Wildfire.gov.  Over the past week, high winds and low relative humidity that dries out vegetation have been stacked on top of the heat, leading to red flag warnings across the Western Slope and fueling extreme fire behavior. After lightning sparked the Lee Fire in Rio Blanco County on Aug. 2, it exploded to more than 58,700 acres โ€” making it the eighth largest wildfire in the stateโ€™s history โ€” in just six days as high winds allowed the fire to surge through dry vegetation.

August 6, 2025

The Middle Colorado Watershed Council (MCWC), in partnership with Garfield County and state and federal funders, broke ground on the Roan Creek Fish Barrier Project on Tuesday, August 5. This long-anticipated conservation infrastructure project has been five years in the making and aligns directly with MCWCโ€™s Integrated Water Management Plan (IWMP), a framework that dovetails with the larger Colorado Water Plan.

Located in a remote stretch of Roan Creek in western Garfield County, the project will construct a permanent fish barrier to protect one of Coloradoโ€™s most unique native fish assemblagesโ€”including a rare genetic strain of Colorado River cutthroat trout, as well as bluehead sucker, Paiute sculpin and speckled dace. These species are increasingly rare across the Colorado River Basin, with cutthroat trout occupying just one percent of their historic range.

The project is primarily funded through the Bureau of Reclamationโ€™s WaterSMART Program, under the Infrastructure Investment and Jobs Act (IIJA). Additional support comes from the Colorado Water Conservation Board (CWCB), Colorado Parks and Wildlife (CPW) , the Colorado River Districtโ€™s Community Funding Partnership and the Trout and Salmon Foundation. In total, the project represents a $1,034,995 investment in watershed health and habitat.

โ€œThis is a win-win for both water users and native fish,โ€ said Garfield County Commissioner Perry Will, who served more than 40 years with CPW, including as a state wildlife officer and supervisor. โ€œGarfield County is proud to support this project as a Category A partner, helping leverage the funding and collaboration it took to get here. The cutthroat trout in Roan Creek represent an incredibly unique genetic lineageโ€”adapted to survive even in 80-degree waters. Keeping nonnative species like brook and rainbow trout out of this system is essential to preserving that rare genetic makeup and ensuring these fish continue to thrive.โ€

The project will also replace outdated irrigation infrastructure, eliminate push-up dams and install a modern concrete diversion with a headgate, fish screen and flow-measuring device โ€”improving efficiency for water users while benefiting stream function and aquatic habitat.

Early funding from the Bureau of Land Management (BLM) supported the 90-percent design phase, completed in 2021 by Wright Water Engineers with guidance from BLM liaison and fisheries biologist Thomas Fresques.

โ€œThe construction of the fish passage barrier on Roan Creek marks a major step toward protecting and sustaining its unique native fishery,โ€ said Assistant Area Wildlife Manager Albert Romero. โ€œFor more than 15 years, CPW and partnersโ€”including the BLM, local landowners and many othersโ€”have worked extensively throughout the drainage to conserve this vital resource.โ€

The Roan Creek Fish Barrier is the result of strong collaboration across local, state and federal partners. Garfield County played a key role as the Category A partner for Bureau of Reclamation funding, helping to secure vital federal support. The Middle Colorado Watershed Council continues to lead grant administration and stakeholder coordination. Wright Water Engineers serves in the project management role, and Kissner General Contractors, Inc. is constructing the structure.

โ€œThe Roan Creek Fish Barrier project is a great example of how targeted, local investments and partnerships can complete projects that support multiple benefits,โ€ said Melissa Wills, Community Funding Partnership Program Manager at the Colorado River District. โ€œUpgrading this infrastructure brings lasting benefits to both native ecosystems and the agricultural community. Through our Accelerator Grant Program, the River District is proud to have helped secure significant state and federal funding and to be part of the collaborative effort that made this project possible.โ€

From email from the Bureau of Reclamation (Conor Felletter):

The Bureau of Reclamation has scheduled an increase in the release from Navajo Dam to 850 cubic feet per second (cfs) from the current release of 800 cfs for Tuesday, August 12, at 4:00 AM. 

Releases are made for the authorized purposes of the Navajo Unit, and to attempt to maintain a target base flow through the endangered fish critical habitat reach of the San Juan River (Farmington to Lake Powell).  The San Juan River Basin Recovery Implementation Program recommends a target base flow of between 500 cfs and 1,000 cfs through the critical habitat area.  The target base flow is calculated as the weekly average of gaged flows throughout the critical habitat area from Farmington to Lake Powell.  

This scheduled release change is subject to changes in river flows and weather conditions. If you have any questions, please contact Conor Felletter (cfelletter@usbr.gov or 970-637-1985), or visit Reclamationโ€™s Navajo Dam website athttps://www.usbr.gov/uc/water/crsp/cs/nvd.html

Reclamation conducts Public Operations Meetings three times per year to gather input for determining upcoming operations for Navajo Reservoir. Input from individuals, organizations, and agencies along with other factors such as weather, water rights, endangered species requirements, flood control, hydro power, recreation, fish and wildlife management, and reservoir levels, will be considered in the development of these reservoir operation plans. In addition, the meetings are used to coordinate activities and exchange information among agencies, water users, and other interested parties concerning the San Juan River and Navajo Reservoir. The next meeting will be held Tuesday, August 19th at 1:00 PM. This meeting is open to the public with hybrid options, in person at the Civic Center in Farmington, NM (200 W Arrington St, Farmington, NM 87401, Rooms 4&5) and virtual using Microsoft Teams. Register for the webinar at this link

On Monday, August 11 at 8pm MT, Reclamation will increase releases from Crystal Dam to 1,700 cfs from the current release of 1,650 cfs. Gunnison Tunnel diversions remain at 1025 cfs. Gunnison River flows in the Black Canyon/Gunnison Gorge, currently ~590 cfs, are anticipated to increase to ~640 cfs. 

Releases are made for the authorized purposes of the Aspinall Unit, and to maintain target base flows through the endangered fish habitat along the Gunnison River between Delta and Grand Junction. 

Reclamation conducts Public Operations Meetings three times per year to gather input for determining upcoming operations for the Aspinall Unit & Gunnison River. Input from individuals, organizations, and agencies along with other factors such as weather, water rights, endangered species requirements, flood control, hydro power, recreation, fish and wildlife management, and reservoir levels, will be considered in the development of these reservoir operation plans. In addition, the meetings are used to coordinate activities and exchange information among agencies, water users, and other interested parties concerning the Aspinall Unit & Gunnison River. The next Operations Group meeting will be held on August 21, 2025 at 1:00 p.m in Montrose, CO at the Holiday Inn Express (1391 S. Townsend Ave). This meeting is open to the public with a virtual option using Microsoft Teams. Register for the webinar at this link.

Key Points

  • The value of the copper beneath Oak Flat drew the attention of a judge hearing arguments to halt a land swap needed to build a huge mine.
  • The federal judge asked attorneys for Resolution Copper and the federal government what could stop the land exchange, which is required by law.
  • No timetable was given for a ruling in the case, but the land swap could occur as early as Aug. 19 if a court doesn’t block it.

U.S. District Court Judge Dominic W. Lanza heard arguments from the San Carlos Apache Tribe and a consortium of environmentalists on Aug. 6 as they seek to overturn a disputed land exchange between the U.S. Forest Service and Resolution Copper. Lanza likened the day’s “very complicated exercise” to pounding a square nail into a round hole. Much of the back-and-forth during the five-hour hearing centered around aย 2022 appraisalย of a 766-acre plot at Oak Flat, the Tonto National Forest campground at the heart of the struggle. Roger Flynn, who represented the environmentalists and inter tribal coalition, argued that the appraisal lacked one essential element: the value of the copper underneath the surface. Some estimates say that about 40 billion pounds of copper lie beneath Oak Flat, currently valued at $4.40 per pound…

Attorneys from the federal government and Resolution Copper, which has sought to obtain Oak Flat to mine for copper, squared off with lawyers from the Arizona Mining Reform Coalition and the San Carlos Apache Tribe, supported by the Inter Tribal Association of Arizona and several environmental organizations, including the Center for Biological Diversity and the Grand Canyon Chapter of the Sierra Club. Although there was no set date for Lanza to rule, he said he was cognizant of the need to rule soon as a 60-day review period nears an end. If no judge intervenes, the land exchange could be finalized as soon as Aug. 19.

Will There Be Enough Water to Make More Semiconductors in the U.S.? — H2ORadio

August 10, 2024

Last week, President Trump said he wants to impose a 100 percent tariff on imports of semiconductors and chipsโ€”but would exempt companies that make them in the United States. Details on a prospective policy were scarceโ€”and also missing in the proposal are plans to address a concern vexing the industryโ€”whereโ€™s all the water going to come from to manufacture chips in the U.S.?

A single fabrication facility, or fab, can use tens of millions of gallons of tap water per day, which is cleaned to become โ€œultrapureโ€ by removing any particles or salts that could damage the chips. Currently, the ultrapure water is used only once to make chips. The wastewater is used to cool the buildings, which get very hot, or in scrubbers that โ€œshower offโ€ gases and other chemical contaminants used in the manufacturing process. 

Several U.S. fabs are currently located in water-stressed areas such as Arizona, so can adding more plants in the country be achieved sustainably? Professor Paul Westerhoff at Arizona State Universityโ€™s School of Sustainable Engineering and the Built Environment told H2O Radio that fabs can be sustainable but would require companies to invest in ways to recycle water to continuously bring it back to an ultrapure state to avoid tapping into local supplies.

He and his colleagues are researching what reuse technologies and policies would be necessary to make facilitates โ€œwater neutralโ€ or at least close to it, some of which would include protecting the watersheds where manufacturers operate.

Another problem in growing the semiconductor industry in the U.S. is climate change. Making semiconductors is energy intensive, so manufacturers would need to switch to renewables instead of fossil fuels to be sustainable. Otherwise, as global temperatures rise and severe droughts increase, the water upon which fabs rely may not be there when theyโ€™re ready.

August 6, 2025

โ€œThereโ€™s just no water in the system,โ€ said Cleave Simpson, the general manager of the Rio Grande Water Conservation District. He was talking to us on Tuesday, Aug. 5, about the startling conditions of the Upper Rio Grande Basin that showed a flow of 36 cubic-feet per second at the Alamosa County line. The river was flowing 15 cfs at the Lobatos Bridge. 

The warnings about this yearโ€™s dryness go back to February when we saw a string of 60-degree days and then more record heat back in April. Fast forward to August and whatโ€™s been a relatively dry summer with less than an inch and a half of accumulated precipitation and we see very little water in the river.

Much of the Great Basin is under intense fire restrictions.

August 6, 2025

The main topic of the most recent Rio Blanco Water Conservancy meeting was news that despite the recent $2.5 Million repair,  the Hydro power unit is not in operation yet. Originally, the hydraulics seized due to solids in the oil, all the oil has been flushed and replaced and the hydraulics are in working order. Currently they are working on the part known as the face seal.  It is being refurbished in California and will be delivered and installed asap.  Once the face seal is installed then RBWCD will finalize wet testing to verify that it is properly functioning before going fully online with it. 

The issue was discovered while the hydro power unit was running during the initial wet testing. They ran the hydro for approximately 12 hours over a couple of days.  At this time is when the stuck face seal was discovered.  It appears that this part may have been faulty for several years and it is the belief of the contractor, engineer and RBWCD Staff that this fix will help remedy these persistent issues the hydro has been having. 

CPW and RBWCD is working on education and prevention for the zebra mussels at Kenney Reservoir. The lake has seen an increase of use due to closures of other lakes in the area due to mussels, capacity restrictions and construction. 

The District continues to solicit responses to their Irrigation Study and Recreation Study and intend on using the results to support in NEPA (National Environmental Protection Act) for the Wolf Creek mega reservoir project. According to Executive Director Alden Vanden Brink, they are having better than expected participation. The next survey will be a Rangely Water Needs assessment.

August 7, 2025

The Pagosa Area Water and Sanitation District (PAWSD) Board of Directors voted at a July 31 special meeting to immediately enter stage two drought under the districtโ€™s drought management plan due to low water levels in area rivers and other concerns. At the meeting, PAWSD District Engineer/Manager Justin Ramsey explained that drought stages for PAWSD are based on water levels in Hatcher Reservoir, which is used to supply water to the uptown Pagosa Springs area; water levels in the San Juan River, which is used to supply water to the downtown area; and what the state drought stage for the area is. He stated that the heaviest weight in the drought calculation is on the level of Hatcher Lake, the second heaviest weight is on the San Juan River and the third heaviest is on the state drought stage.

Ramsey noted that Hatcher is in โ€œreally good shape…However, Ramsey commented that the San Juan River is โ€œlowโ€ at 48 cubic feet per second (cfs) as of the day of the meeting and that the state drought stage for the area is stage two, which indicates severe drought.

August 5, 2025

These days, thereโ€™s a lot that divides the Colorado delegation along party lines. But one thing theyโ€™re all in agreement on is the need for the federal government to release about $140 million itโ€™s holding onto for 15 water projects across the state.

โ€œWe ask you to move forward with obligating the remaining $140 million worth of Bucket 2 projects in Colorado โ€“ not just for the benefit of our state, but for the resilience of the entire Colorado River Basin,โ€ urges the delegation letter [from Sen. John Hickenlooper, Hurd, Sen. Michael Bennet, and Reps. Jeff Crank, Joe Neguse, Gabe Evans, Brittany Pettersen, Lauren Boebert, Diana DeGette and Jeff Crow].

Among the awards was $40 million to purchase the Shoshone water rights from Xcel Energy and transfer them to the Colorado River District. The other projects deal with watershed restoration, restoring or improving habitats, improving wetlands and improving water health. As the letter points out, Congress allocated $4 billion in Bidenโ€™s signature climate, tax and health care law to deal with theย ongoing drought in the Colorado River Basin.ย The Bucket 2 funding was awarded on January 17, but that was just the first step for money to be distributed to the projects. Typically, contracts or agreements have to be signed before the money is actually obligated and distributed. Still, even if that had been completed before the change of administrations, one of Trumpโ€™s first executive ordersย paused all funding appropriated through the IRA.

President Trump’s war on energy: If we’re in an energy emergency, why kill the cleanest, best, and fastest growing sources? — Jonathan P. Thompson (LandDesk.org)

๐ŸŒต Public Lands ๐ŸŒฒ

During both the Obama and Biden presidencies, Republicans and the fossil fuel industry often accused the administration of waging a โ€œwar on energy.โ€ It was a demonstrably false allegation. The most either of the Democrats did to attack the energy industry was to incrementally increase common sense regulations and environmental protections, which apparently did little to hamper energy development. The so-called shale revolution, when โ€œfrackingโ€ opened up huge new reserves of tight oil and gas, began under Obama, and truly came to fruition under Biden, when domestic oil and gas production reached new record highs. Meanwhile, Bidenโ€™s Interior Department approved dozens of utility-scale solar and wind and long-delayed transmission projects on public lands.

But now the Trump administration is, in fact, waging a very real war on energy โ€” renewable energy, that is, namely wind and solar power. Theyโ€™ve frozen and even clawed back funds for projects, killed federal clean energy tax credits, subjected wind and solar projects on public lands to heightened reviews, and eliminated wind energy leasing areas off Oregonโ€™s coast. And theyโ€™ve done it all as America is supposedly gripped by an โ€œenergy emergency.โ€

Now, the Interior Department has gone even further with a new order that threatens to kill all new renewable power development on federal lands. I know there are some readers out there who might applaud this, since so many of our public lands are not suited for sprawling utility-scale solar or wind developments. But this order โ€” deceptively and cynically titled, โ€œManaging Federal Energy Resources and Protecting the Environmentโ€ โ€” would potentially replace proposed wind and solar projects with coal or uranium mines and/or power plants, oil and gas fields, or other non-renewable energy projects.

The order requires land management agencies, when reviewing proposed solar or wind energy projects, to consider โ€œa reasonable range of alternatives that includes projects with capacity densities meeting or exceeding that of the proposed project.โ€

Capacity density is basically the amount of energy a project can generate per acre. According to the Interior Departmentโ€™s calculations (weโ€™ll get to the flaws there in a moment), the capacity density (megawatts/acre) for various power sources are:

  • Advanced nuclear reactor: 33.17 MW/acre
  • Combined cycle gas plant: 5.4 to 24.42 MW/acre (depending on configuration)
  • Gas combustion turbine: 2.13 to 4.23 MW/acre
  • Ultra-supercritical coal plant w/out carbon capture: .69 MW/acre
  • Geothermal: .16
  • Solar PV w/ battery storage: .04
  • Onshore wind: .01
  • Offshore wind: .006

In other words, wind and solar are the big losers, taking up far more space to generate the same amount of electricity as, say, a nuclear plant. According to the new order, this raises the question of โ€œwhether the use of federal lands for any wind and solar projects is consistent with the law.โ€

This isnโ€™t a new argument: The specter of โ€œrenewable energy sprawlโ€ has long been wielded to push back against solar and wind development. And certainly the amount of space a project takes up should be one of many considerations in whether to permit it. But should it really have more weight than the amount of damage the project would inflict? How about pollutants emitted per megawatt, or amount of harm to people, the climate, and the environment per megawatt? Is there consideration for the fact that there is a lot of space between the turbines within a wind facility that is minimally affected? And why doesnโ€™t their chart include hydroelectric, which has the lowest capacity density of all?

Also, the Interior Departmentโ€™s calculations are a bit fishy, or at least incomplete. They say they are based on a 2023 Sargent & Lundy report commissioned by the Energy Information Administration. The report is not on capacity density, but rather the costs of building and operating various power generating technologies. When determining the acreage of the nuclear and fossil fuel plants, they do not take into account the land required for fuel production, which can be extensive.

The supercritical coal plant referenced in the report, for example, would require a mere 600 acres. Yet, the Four Corners coal plant in northwestern New Mexico โ€” along with its associated Navajo Mine (current mining areas as well as reclaimed areas), Morgan Lake, and coal combustion waste disposal facilities โ€” covers (and wrecks) some 15,000 acres. That acreage will continue to grow for as long as the plant operates, since the mine and waste dumps will continue to expand. Compare that to the 2,400 acres covered by the nearby San Juan solar plant.

Iโ€™d also argue that if the goal is to get the most energy out of every acre of public land (which is a silly goal, but whatever), then they should figure in the amount of energy the proposed project consumes. Coal mining and oil and gas drilling require large amounts of electricity and petroleum (along with human labor, which is also a form of energy), as does transporting coal and gas by train and pipeline. Uranium enrichment, which is necessary to produce reactor fuel, is extremely power-intensive.

None of this really matters to Interior Secretary Doug Burgum, however. Thatโ€™s because he knows weโ€™re not really in an โ€œenergy emergency,โ€ and that it is merely a fabricated excuse to give more handouts and regulatory relief to his fossil fuel-industry buddies and to get revenge on Trumpโ€™s political opponents by punishing cleaner energy sources.

Proposed utility-scale solar and wind facilities on public lands should by all means be scrutinized and subjected to the same reviews as any other projects, contrary to what the Abundance faction might believe. The projects should be denied if their impacts outweigh the benefits, with bonus benefit-points for solar or wind projects that displace or replace coal or natural gas generation.

But judging the projects based on a virtually meaningless metric is not only spiteful, unfair, and stupid, but it also will needlessly hamper the fight against health-harming pollution and climate change. And thatโ€™s simply irresponsible, at best. [ed. emphasis mine]

โ›๏ธ Mining Monitor โ›๏ธ

Speaking of fake energy emergencies โ€ฆ In May, the Bureau of Land Management completed its environmental review and approval of the Velvet-Wood uranium mine in Utahโ€™s Lisbon Valley in just 11 days. The rush, sans public input, ostensibly was necessary to get the mine online quickly to address the supposed uranium shortage.

The mineโ€™s proponent, Anfield Resources, apparently doesnโ€™t share the Trump administrationโ€™s sense of urgency. At the end of April, the Utah Division of Oil, Gas, and Mining asked Anfield for more information on its application to commence large mining operations, which was deemed technically incomplete. Anfield has yet to respond. The company is also not rushing forward to get state approval for its water treatment plant permit or to reopen its Shootaring Mill near Ticaboo, where the Velvet-Woodโ€™s uranium would be processed.

In other words, the fast-tracked permitting was merely a ruse, intended to bypass environmental regulations and public input, not to expedite the project, itself.

Itโ€™s the tenth anniversary of the Gold King Mine blowout that affected the Animas and San Juan rivers in Colorado, New Mexico, and Utah. A few folks have asked if Iโ€™m going to write anything about it โ€” since I did write a book about it โ€” but I donโ€™t think thereโ€™s much more to say, really.

The Gold King Mine continues to drain acidic, heavy metal-laden water โ€” though it is being treated before itโ€™s released into the watershed โ€” and neighboring mines continue to do the same (though they arenโ€™t being treated). Superfund designation hasnโ€™t been the boon to water quality that some hoped for, nor did it stigmatize Silverton as many feared it would (property values continue to soar into the unreachable zone).

While the event did bring more attention to the problem of abandoned mine sites (even though the Gold King wasnโ€™t technically abandoned when it blew out), and injected โ€œacid mine drainageโ€ into the publicโ€™s vocabulary, it hasnโ€™t led to mining law reform or any widespread effort to address the issue. That said, Congress finally did pass a Good Samaritan bill, that might clear the way for volunteer groups to do some additional cleanup without being sued for it. Still, they need funding, and thatโ€™s in short supply these days.

Fire season is really heating up, along with the summer temperatures. The relatively dry spring was followed by higher than normal temperatures in July and zero to minimal precipitation in many places, turning low- and mid-elevation forests to kindling. Officials working the Leroux Fire west of Paonia said the relative humidity was just 2%, contributing to rapid fire growth.

The Leroux blaze was just one of many new starts on Coloradoโ€™s Western Slope over the last several days. The Sharp Canyon Fire north of Cahone, Colorado, grew rapidly to 400 acres on Monday, forcing evacuations, but it seems to have quieted down overnight. The Lee and Elk fires in Rio Blanco County blew up to 13,000 and 7,700 acres, respectively, over a couple of days. The Middle Mesa Fire east of Navajo Reservoir and just south of the Colorado-New Mexico line grew to 2,500 acres as of Monday night.

Meanwhile, the Dragon Bravo Fire on the Grand Canyonโ€™s North Rim has lived up to its name, reaching 126,445 acres as of Tuesday morning with only 13% containment a month after it ignited.

The situation is probably going to get worse before it gets better. The National Weather Service has issued red flag warnings for parts of Nevada, Utah, Colorado, and Wyoming, with extreme heat warnings in parts of Arizona and southern California. The mercury in Moab is expected to reach 100ยฐ F or more every day this week, and thereโ€™s no significant rainfall in sight.

As the Colorado River slowly dries up, states angle for influence over future waterย rights

The Colorado River is in trouble: Not as much water flows into the river as people are entitled to take out of it. A new idea might change that, but complicated political and practical negotiations stand in the way.

The river and its tributaries provide water for about 5 million acres of cropland and pasture, hydroelectric power for millions of people, recreation in the Grand Canyon, and critical habitat for fish and other wildlife. Thirty federally recognized Native American tribes assert rights to water from the Colorado River system. It is also an important source of drinking water for cities within the Colorado River Basin, including Phoenix, Tucson and Las Vegas, and cities outside the basin, such as Los Angeles, San Diego, Salt Lake City, Denver and Albuquerque.

The seven Colorado Basin states have been grappling with how to deal with declining Colorado River supplies for a quarter century, revising usage guidelines and taking additional measures as drought has persisted and reservoir levels have continued to decline. The current guidelines will expire in late 2026, and talks on new guidelines have been stalled because the states canโ€™t agree on how to avoid a future crisis.

In June 2025, Arizona suggested a new approach that would, for the first time, base the amount of water available on the riverโ€™s actual flows, rather than on reservoir level projections or historic apportionments. While the proposal has been praised as offering โ€œa glimmer of hope,โ€ coming to agreement on the details presents daunting challenges for the Colorado Basin. https://public.tableau.com/views/ColoradoRiverBasin/ColoradoRiverbasin?:language=en-US&:sid=&:redirect=auth&:display_count=n&:origin=viz_share_link&:showVizHome=no&:embed=true

The Colorado River Compact

The 1922 Colorado Compact divided the 250,000-square-mile Colorado River Basin into an Upper Basin โ€“ which includes parts of Colorado, New Mexico, Utah and Wyoming, as well as the northeastern corner of Arizona โ€“ and a Lower Basin, encompassing most of Arizona and parts of California and Nevada. The compact apportions each basin 7.5 million acre-feet of water from the river each year. An acre-foot of water is enough to cover 1 acre in water 1 foot deep, which amounts to approximately 326,000 gallons. According to a 2021 estimate from the Arizona Department of Water Resources, 1 acre-foot is sufficient to supply 3.5 single-family households in Arizona for one year.

Anticipating a future treaty with Mexico for sharing Colorado River water, the compact specified that Mexico should be supplied first with any surplus available and any additional amount needed โ€œborne equallyโ€ by the two divisions. A 1944 water-sharing treaty between Mexico and the U.S. guarantees Mexico at least 1.5 million acre-feet of Colorado River water annually.

The compact also specified that the Upper Basin states of Colorado, New Mexico, Utah and Wyoming โ€œwill not cause the flow of the river โ€ฆ to be depleted below an aggregate of 75,000,000 acre-feet for any period of 10 consecutive years.โ€

The Lower Basin states of Arizona, California and Nevada contend that this provision is a โ€œdelivery obligation,โ€ requiring the Upper Basin to ensure that over any 10-year period, a total of at least 75 million acre-feet flows to the Lower Basin.

By contrast, the Upper Basin states contend that the language merely creates a โ€œnon-depletion obligationโ€ that caps their collective use at 7.5 million acre-feet per year in times when additional use by the Upper Basin would cause less than 75 million acre-feet to be delivered to the Lower Basin over a 10-year period.

This disagreement over the compactโ€™s language is at the heart of the differences between the two basins.

A small source area

Nearly all of the water in the Colorado River system comes from snow that falls in the Rocky Mountains in the Upper Basin. About 85% of the Colorado Basinโ€™s flows come from just 15% of the basinโ€™s surface area. Most of the rest of the basinโ€™s lands are arid or semi-arid, receiving less than 20 inches of precipitation a year and contributing little to the flows of the Colorado River and its tributaries.

Rain and snowfall vary dramatically from year to year, so over the course of the 20th century, the Colorado Basin states โ€“ with the assistance of the U.S. Bureau of Reclamation, the agency of the Department of the Interior responsible for operating federal water and power projects in the U.S. West โ€“ developed a complex system of reservoirs to capture the extra water in wet years so it could be available in drier years. The most notable reservoirs in the system are Lake Mead, impounded by Hoover Dam, which was completed in 1936, and Lake Powell, impounded by Glen Canyon Dam, completed in 1966.

Over the past 25 years, the quantity of water stored in Lake Mead and Lake Powell has declined significantly. A primary driver of this decline is a lengthy drought likely amplified by climate change: One study estimated that the region may be suffering its driest spell in 1,200 years.

But human errors are also adding up. The Colorado Compactโ€™s original negotiators made unrealistically optimistic assumptions about the riverโ€™s average annual flow โ€“ perhaps knowingly. In their book โ€œScience be Dammed,โ€ Colorado River experts Eric Kuhn and John Fleck document how compact negotiators willfully or wishfully ignored available data about the riverโ€™s actual flows. Kuhn and Fleck argue the negotiators knew it would be decades before demand would exceed the riverโ€™s water supply, and they wanted to sell a big vision of Southwestern development that would merit massive federal financing for reservoirs and other infrastructure.

In addition, the current Colorado River system accounting does not factor in the roughly 1.3 million acre-feet of water lost annually from Lake Mead due to evaporation into the air or seepage into the ground. This accounting gap means that under normal annual releases to satisfy the apportionments to the Lower Basin and Mexico, Lake Meadโ€™s water level is steadily declining.

Stabilization efforts

The seven Colorado River states and Mexico have taken significant steps to stabilize the reservoirs. In 2007, they agreed to new guidelines to coordinate the operations of Lake Mead and Lake Powell to prevent either reservoir from reaching catastrophically low levels. They also agreed to reduce the amount of water available to Arizona and Nevada depending on how low Lake Meadโ€™s levels go.

When the 2007 guidelines proved insufficient to keep the reservoir levels from declining, the Colorado Basin states and Mexico agreed in 2019 to additional measures, authorizing releases from Upper Basin reservoirs under certain conditions and additional cuts to water users in the Lower Basin and Mexico.

By 2022, projections for the reservoir levels looked so dire that the states started negotiating additional near-term measures to reduce the amount of water users withdrew from the river. The federal government helped out, too: $4 billion of Inflation Reduction Act funding has helped pay the costs of water-conservation measures, primarily by agricultural districts, cities and tribes.

These reductions are real. In 2023, Arizona, California and Nevada used only 5.8 million acre-feet of Colorado River water โ€“ their lowest combined annual consumption since 1983. The Lower Basinโ€™s total consumption in 2024 was slightly higher, at 6.09 million acre-feet.

A new opportunity?

With the 2007 guidelines and additional measures expiring in 2026, the deadline for a new agreement looms. As the Colorado River states try to work out a new agreement, Arizonaโ€™s new proposal of a supply-driven approach offers hope, but the devilโ€™s in the details. Critical components of that approach have not been ironed out โ€“ for instance, the percentage of the riverโ€™s flows that would be available to Arizona, California and Nevada.

If the states canโ€™t agree, there is a chance that the secretary of the Interior, acting through the Bureau of Reclamation, may decide on his own how to balance the reservoirs and how much water to deliver out of them. That decision would almost certainly be taken to court by states or water users unhappy with the result.

And the Lower Basin states have said they are fully prepared to go to court to enforce what they believe to be the Upper Basinโ€™s delivery obligation, which, the Upper Basin has responded, it is prepared to dispute.

In the meantime, farmers in Arizonaโ€™s Yuma County and Californiaโ€™s Imperial County cannot be sure that in the next few years they will have enough water to produce winter vegetables and melons for the nation. The Colorado River Basinโ€™s municipal water providers are worried about how they will meet demands for tap water for homes and businesses. And tribal nations fear that they will not have the water they need for their farms, communities and economies.

This Week’s Drought Summary

It was a week with a lot of change noted in areas of dryness and drought across the U.S. Heavy to locally excessive rainfall engendered broad areas of improvement in much of the Southeast, the lower Great Lakes Region, the central and northern Great Plains, and many locations across the High Plains and adjacent southern Rockies. Meanwhile, continued subnormal precipitation and episodes of unusually hot weather, low humidity, and high winds led to large areas of deterioration in the central and northern Rockies. Also, emerging short-term precipitation deficits led to the introduction of scattered areas of abnormal dryness (D0) over parts of the Middle and Lower Mississippi Valley, the Tennessee Valley, and near the western foothills of the western Appalachians. A few spots of deterioration were also introduced in western portions of the Southeast (where typical summer shower and thunderstorm activity has been less robust than usual) and Southwest (where subnormal monsoonal rains have been observed)…

High Plains

Rainfall varied in intensity across the High Plains Region, with abundant rainfall amounts falling on a large part of the Plains while lesser, subnormal totals were observed in the higher elevations farther west. A similar pattern has been observed periodically for several weeks now, resulting in significantly worse conditions in the western part of the region than farther east. A solid swath of moderate drought (D1) or worse covers most of southern and western Wyoming and the western half of Colorado, with severe drought (D2) covering a large part of this region, and extreme drought (D3) noted in a sizeable portion of west-central and northwestern Colorado. This represents a significant increase in the extend of D2 and D3 coverage compared to last week. In contrast, another wet week led to a continued reduction in the coverage of the abnormal dryness (D0) to locally severe drought (D2) over the Great Plains. A broken pattern of heavy rainfall โ€“ with upwards of 3 inches reported in spots โ€“ prevailed from northern Kansas through much of the Dakotas, although higher amounts were more common in some areas than others. The improvements left severe drought confined to part of south-central Nebraska and adjacent Kansas, southwestern Nebraska, and a small area in south-central South Dakota. Moderate drought (D1) coverage also decreased, mainly across Nebraska and a few adjacent locations in the far eastern sections of Colorado and Wyoming. The USDA reported short or very short subsoil moisture across about one-third of Colorado and two-thirds of Wyoming. In addition, 17 percent of the Colorado corn crop was in poor or very poor condition, and drier weather earlier in the summer has left one-third of the Nebraska oat crop in poor or very poor condition…

West

Heavy precipitation prompted significant areas of improvement across the southeastern and northern sections of the West Region, but hot and dry weather has caused dryness and drought to intensify in central parts of the Region, across Utah, eastern Nevada, and northeastern Arizona (similar to the situation in western parts of Colorado and Wyoming). Reports of 2 or more inches of rain were fairly common across southeastern and north-central through northwestern Montana as well as northeastern New Mexico, with lesser amounts in other parts of these states. These rains brought 2-week totals to between 2 and 5 inches in much of New Mexico and Montana, with locally higher totals, especially in north-central Montana and northeastern New Mexico. This prompted broad improvements through both states, but even so, areas that missed most of the rain in these states remained entrenched in drought. Exceptional drought (D4) persisted in part of southwestern New Mexico, and extreme drought (D3) remained across north-central and southwestern parts of the state, along with a significant swath of west-central Montana. Moderate to severe drought still affected a large part of the remainders of these states despite improvements, and only the southeastern quarter of Montana and northeastern New Mexico have completely emerged from any designation of dryness or drought. Farther west, showery weather has occurred periodically for the past few weeks in central and eastern Oregon, leading to a reduction in the coverage of dryness and drought there. Across central parts of the West Region from eastern Nevada through Utah, rainfall has been far less generous, and drought either persisted or deteriorated here. The entire region is experiencing at least moderate drought at this point, with widespread D2 conditions across eastern and western Utah, and adjacent Nevada. Some expansion of extreme drought (D3) occurred in east-central and northeastern Utah, where conditions have been similar to those observed across western parts of Colorado and Wyoming. Elsewhere, no changes were observed, and broad areas of drought remained entrenched. USDA reports that 50 percent of the Barley crop and 48 percent of the spring wheat crop in Washington was in poor or very poor condition, as were 26 percent of the barley crop and 47 percent of spring wheat in Montana. In addition, 90 percent of Nevada rangeland was in poor or very poor condition…

South

Outside southern and western Texas, not much dryness or drought has been observed across the South Region. But after a few relatively dry weeks, short-term precipitation shortfalls have developed in portions of Arkansas and Tennessee, leading to the introduction of a few patches of abnormal dryness (D0) in areas of significant 30-day rainfall shortages and near- to below-normal 60-day totals. A much larger proportion of these two states report 30-day precipitation deficits, but above-normal 60-day totals precluded more expansive D0 development this week, although the situation will need to be monitored going forward. In Tennessee, some patches of abnormal dryness and isolated moderate drought (D0 and D1) was assessed last week. In the easternmost parts of the state, heavy rains engendered a bit of improvement, but the burgeoning dryness farther west allowed a few additional spots of moderate drought to develop. To the west, rainfall was sufficient to end the fledgling area of abnormal dryness in southwestern Oklahoma, but more widespread and intense drought continued to cover large parts of western and southern Texas. Moderate to heavy rainfall was observed over parts of the drought-affected region, leading to some improvement in the Big Bend and along the northern fringe of the region. Substantial rainfall evaded areas farther to the south, however, allowing for some expansion of D0 and D1 conditions in the southernmost parts of the state. Since early May, rainfall totals exceed 3 inches in portions of south-central Texas, and approach 6 inches in part of the Big Bend. Despite recent improvement in much of the state, however, a small patch of exceptional drought (D4) persisted in upper South Texas, and severe drought continued in adjacent areas as well as parts of the Rio Grande Valley and Big Bend. But despite recent drought improvement, 22 percent of the Texas cotton crop and 48 percent of its oat crop was in poor to very poor conditions, according to USDA.

Looking Ahead

From August 7 to 11, an area of showers and thunderstorms off the Southeastern Coast may develop into a tropical system according to the National Hurricane Center, but this is far from certain. Any organized system is expected to remain off the East Coast, but early in the period the disorganized convection is expected to impact the South Atlantic Coastline. Generally 1 to locally over 3 inches of rain are forecast for coastal sections of South Carolina, Georgia, and northern Florida while similar amounts are forecast along the central and eastern Gulf Coast, and much of the Florida Peninsula. Between 1 and 3 inches are anticipated near a frontal system stretching from the Middle Mississippi Valley into the Great Lakes Region, and amounts in the lower part of that range are forecast in scattered parts of the central and northern Plains. Moderate amounts of several tenths to around an inch should fall in many areas from the Upper Mississippi Valley into the Northern Intermountain West, portions of the central Plains, and areas near the Southeastern and Gulf Coasts. Light precipitation is possible in parts of the central and eastern Four Corners States, the central Ohio Valley, the southern Appalachians, the mid-Atlantic, and upper New England. Other areas are expecting little if any precipitation. Meanwhile a cooler than normal but moderating air mass should allow temperatures to average near or slightly below normal in the Southeast and mid-Atlantic while daily highs should average a few degrees below normal in and around the northern High Plains. In most other locations, temperatures should average a little above normal as above-normal temperatures begin to slowly cover most of the Contiguous States. The greatest positive temperature departures are expected where above-normal temperatures have already settled in, specifically parts of the interior West and the Northeast, where highs will average 6 to 12 deg. F in spots.

The Climate Prediction Centerโ€™s 6-10 day outlook (valid August 12-16, 2025) features significant uncertainty in the precipitation outlook. Odds for above-normal precipitation exceeding 40 percent across most of Alaska outside the northeast and southwest sections, and nowhere else. There are, however, fairly broad areas with slightly enhanced chances (33 to 40 percent) for wetter than normal wetter; specifically, the remainder of Alaska, the northern tier of the Contiguous 48 States, the Sonoran Desert, the eastern Great Plains, the Mississippi and Ohio Valleys, the Great Lakes Region, the upper Southeast, the mid-Atlantic, and inland sections of the Northeast and New England. Drier than normal conditions are slightly favored in the Great Basin and adjacent sections of the Rockies and Pacific Northwest. There is more certainty in the temperature forecast, with above-normal temperatures favored across a large part of the Contiguous States, and Hawaii. The best odds (over 70 percent) cover the Northeast and New England while the central West Coast, parts of the Four Corners States, the eastern Great Lakes, the mid-Atlantic, the coastal Southeast, and the Florida Peninsula have 60 to 70 percent chances for unusually high temperatures. Only Alaska and the northern High Plains are not areas where warmer than normal conditions are favored. In fact, subnormal temperatures are favored over most of Alaska, with odds topping 60 percent in northwestern parts of the state.

August 6, 2025

High winds and extreme drought conditions in northwest Colorado have fueled the rapid growth of two wildfires this week near Meeker in Rio Blanco County, where firefighting crews say theyโ€™re prioritizing structure protection with โ€œlimited resourcesโ€ on hand.

The Lee Fire, west of Meeker, nearly doubled in size Tuesday and has now burned 22,497 acres, predominantly on Bureau of Land Management land south of Colorado Highway 13. About 20 miles to the east, the Elk Fire is estimated at 8,304 acres in size. Both fires are believed to have been started by lightning strikes on Aug. 2.

Jeramy Dietz, operations section chief with the Rocky Mountain Incident Management Team responding to both fires, said in a video update Wednesday that crews are developing plans โ€œbased on our highest values at risk, with our limited resources that we have on hand.โ€

With the latest growth, the estimated area burned in Colorado by 11 major wildfires in 2025 now stands at 64,196 acres, according to federal data. That doesnโ€™t include smaller fires suppressed by state and local first responders, but it already makes for the stateโ€™s worst fire year since 2020, when multiple historic blazes burned a record-setting 625,357 acres, according toย National Interagency Fire Centerย data.

Other large Colorado fires this summer include the Turner Gulch Fire, which has burned over 24,000 acres east of Gateway, near the Colorado-Utah border, and is currently 49% contained; and the 4,232-acre South Rim Fire, which has forced the closure of parts of Black Canyon of the Gunnison National Park and is estimated at 52% containment.

Drought conditions classified as โ€œsevereโ€ or โ€œextremeโ€ currently extend across the majority of Coloradoโ€™s western half, according to the U.S. Drought Monitor. A critical fire weather advisory for western Colorado and several neighboring states has been issued by the Rocky Mountain Area Coordination Center, a Denver-based branch of the NIFC, and will remain in place through at least mid-August.

โ€œAfter a dry winter with minimal snowpack fuel moistures are well below normal, and much of the region is under severe to extreme drought,โ€ the agency warns. โ€œExtreme fire behavior marked by rapid spread, torching, and resistance to control is being driven by critically dry โ€ฆ fuels, and drought-stressed brush and trees. As heat intensifies and fuel moistures decline further, fire potential will remain elevated across the area.โ€

Colorado public health officials have issued health advisories for wildfire smoke in 17 counties across the state, including the Denver area and the northern Front Range. People โ€œwith heart disease, respiratory illnesses, the very young, and older adultsโ€ are advised to limit outdoor activities.

Due to climate change, much of Colorado has grown hotter and drier in recent decades, increasing wildfire risk. The three largest wildfires in Colorado history all occurred in 2020, and the stateโ€™s 20 biggest fires on record have all occurred in the past 20 years. Rising levels of greenhouse gases, mostly the result of fossil-fuel combustion, have caused much of the Western Slope to warm by an average of more than 4 degrees Fahrenheit above pre-industrial levels, and the regionโ€™s current โ€œmegadroughtโ€ is its worst dry spell in at least 1,200 years.

First-ever airborne toxin detected in Western Hemisphere — Daniel Katz, Ellie Browne, and Stephanie Maltarich (University of #Colorado #Boulder)

June 9, 2025

Once in a while, scientific research resembles detective work. Researchers head into the field with a hypothesis and high hopes of finding specific results, but sometimes, thereโ€™s a twist in the story that requires a deeper dive into the data.

That was the case for CU Boulder researchers who led a field campaign in an agricultural region of Oklahoma. Using a high-tech instrument to measure how aerosol particles form and grow in the atmosphere, they stumbled upon something unexpected: the first-ever airborne measurements of Medium Chain Chlorinated Paraffins (MCCPs), a kind of toxic organic pollutant, in the Western Hemisphere. Their results published today in ACS Environmental Au.

โ€œIt’s very exciting as a scientist to find something unexpected like this that we weren’t looking for,โ€ said Daniel Katz, CU Boulder chemistry PhD student and lead author of the study. โ€œWe’re starting to learn more about this toxic, organic pollutant that we know is out there, and which we need to understand better.โ€ 

MCCPs are currently under consideration for regulation by the Stockholm Convention, a global treaty to protect human health from long-standing and widespread chemicals. While the toxic pollutants have been measured in Antarctica and Asia, researchers havenโ€™t been sure how to document them in the Western Hemisphereโ€™s atmosphere until now. 

MCCPs are used in fluids for metal working and in the construction of PVC and textiles. They are often found in wastewater and as a result, can end up in biosolid fertilizer, also called sewage sludge, which is created when liquid is removed from wastewater in a treatment plant. In Oklahoma, researchers suspect the MCCPs they identified came from biosolid fertilizer in the fields near where they set up their instrument.

โ€œWhen sewage sludges are spread across the fields, those toxic compounds could be released into the air,โ€ Katz said. โ€œWe can’t show directly that that’s happening, but we think it’s a reasonable way that they could be winding up in the air. Sewage sludge fertilizers have been shown to release similar compounds.โ€

MCCPs little cousins, Short Chain Chlorinated Paraffins (SCCPs), are currently regulated by the Stockholm Convention, and since 2009, by the EPA here in the United States. Regulation came after studies found the toxic pollutants, which travel far and last a long time in the atmosphere, were harmful to human health. But researchers hypothesize that the regulation of SCCPs may have increased MCCPs in the environment. 

โ€œWe always have these unintended consequences of regulation, where you regulate something, and then there’s still a need for the products that those were in,โ€ said Ellie Browne, CU Boulder chemistry professor, CIRES Fellow, and co-author of the study. โ€œSo they get replaced by something.โ€ 

Using a nitrate chemical ionization mass spectrometer, which allows scientists to identify chemical compounds in the air, the team measured air at the agricultural site 24 hours a day for one month. As Katz cataloged the data, he documented the different isotopic patterns in the compounds. The compounds measured by the team had distinct patterns, and he noticed new patterns that he immediately identified as different from the known chemical compounds. With some additional research, he identified them as chlorinated paraffins found in MCCPs.

Katz says the makeup of MCCPs are similar to PFAS, long-lasting toxic chemicals that break down slowly over time. Known as โ€œforever chemicals,โ€ their presence in soils recently led the Oklahoma Senate to ban biosolid fertilizer

Now that researchers know how to measure MCCPs, the next step might be to measure the pollutants at different times throughout the year to understand how levels change each season. Many unknowns surrounding MCCPs remain, and thereโ€™s much more to learn about their environmental impacts. 

โ€œWe identified them, but we still donโ€™t know exactly what they do when they are in the atmosphere, and they need to be investigated further,โ€ Katz said. โ€œI think it’s important that we continue to have governmental agencies that are capable of evaluating the science and regulating these chemicals as necessary for public health and safety.โ€

Uranium Company Receives #Wyomingโ€™s First Fast-Tracked Mining Permits — Jake Bolster (InsideClimateNews.org)

August 6, 2025

The state could eventually host the nationโ€™s largest uranium production facility to use two different mining methods. Environmentalists worry that expedited permitting in the nuclear sector could threaten โ€œsafety, environmental quality and public trust.โ€

Uranium Energy Corp.โ€™s Sweetwater uranium project has become the first mining proposal in Wyoming to be fast-tracked under President Donald Trumpโ€™s March executive order to increase U.S. mineral production. 

The company announced Aug. 5 that it planned to expand its uranium mining operations in Wyomingโ€™s Red Desert as a result of the expedited permitting process. The federal government expects to post a permitting timetable for the project by Aug. 15.

Through other executive orders, the dismantling of environmental regulations and the spending bill congressional Republicans passed in July, the second Trump administration has made it easier for extractive industries to receive permits for mining on public lands. Trump has classified uranium as a โ€œcritical mineralโ€ for the U.S., which imported 99 percent of its fuel for nuclear energy in 2023, according to data from the U.S. Energy Information Administration.

John Burrows, energy and climate policy director at the Wyoming Outdoor Council, saw the fast-tracking news as evidence of a pattern in the stateโ€™s nascent nuclear industry. 

โ€œAcross the nuclear supply chain weโ€™re seeing permits getting expedited and weโ€™re having concerns around safety, environmental quality and public trust,โ€ he said. 

Last month, the U.S. Nuclear Regulatory Commission accelerated its review of an advanced nuclear reactor being built in Kemmerer, Wyoming, with an end-of-year completion goal. TerraPower, the company behind the new technology, was co-founded by billionaire Bill Gates.

Uranium Energyโ€™s Sweetwater permits were fast-tracked by the Federal Permitting Improvement Steering Council. Trumpโ€™s March executive order required the executive director of the council to publish such projects on a special dashboard.

โ€œI am excited to welcome the Sweetwater Complex to the FAST-41 transparency dashboard in support of President Trumpโ€™s goal of unlocking Americaโ€™s mineral resources,โ€ said Emily Domenech, the councilโ€™s executive director, in a statement accompanying Uranium Energyโ€™s announcement. โ€œThe uranium that this project can produce would be game-changing for our nation as we work to reduce our reliance on Russia and China, strengthen our national and economic security, and reestablish a robust domestic supply chain of nuclear fuel.โ€

The Federal Permitting Improvement Steering Council was established in 2015 under President Barack Obama and made permanent by President Joe Bidenโ€™s Infrastructure Investment and Jobs Act in 2021.

If approved, Uranium Energy expects to begin โ€œin-situโ€ uranium mining within its permit boundaries. The process involves leaching uranium from underground rock and does less surface disturbance than conventional strip-mining methods. The company already operates conventional uranium mines in Wyoming but wants to expand its claim to include nearby areas it says are suitable for in-situ retrieval methods. 

โ€œThis will provide the Company unrivaled flexibility to scale production across the Great Divide Basin,โ€ Amir Adnani, Uranium Energyโ€™s president and CEO, said in an email.

If Uranium Energy receives its permits, which could still take years, the company said its Sweetwater facility will become the largest in the United States capable of processing both conventionally and in-situ-mined uranium. Its current licensed production capacity at the Sweetwater facility is 4.1 million pounds of uranium annually, the company said.

National parks are key conservation areas for wildlife and naturalย resources

The United Statesโ€™ national parks have an inherent contradiction. The federal law that created the National Park Service says the agency โ€“ and the parks โ€“ must โ€œconserve the scenery and the natural and historic objects and the wildlife โ€ฆ unimpaired for the enjoyment of future generations.โ€

That means both protecting fragile wild places and making sure people can visit them. Much of the public focus on the parks is about recreation and enjoyment, but the parks are extremely important places for research and conservation efforts.

These places contain a wide range of sensitive and striking environments: volcanoes, glaciers, sand dunes, marshlands, ocean ecosystems, forests and deserts. And these areas face a broad variety of conservation challenges, including the effects of climate change, the perils of popularity driving crowds to some places, and the Trump administrationโ€™s reductions to park service staff and funding.

As scholars of recreation who study the national parks and teach a course on them, we have seen the park service make parks far more than just recreational opportunities. They are living laboratories where researchers โ€“ park service personnel and others โ€“ study nature across wide-ranging ecosystems and apply what they learn to inform public and private conservation efforts around the country.

Returning wolves to Yellowstone

One of the best known outcomes of conservation research in park service history is still playing out in the nationโ€™s first national park, Yellowstone.

Gray wolves once roamed the forests and mountains, but government-sanctioned eradication efforts to protect livestock in the late 1800s and early 1900s hunted them to near extinction in the lower 48 states by the mid-20th century. In 1974, the federal government declared that gray wolves needed the protections of the Endangered Species Act.

Research in the park found that the ecosystem required wolves as apex predators to maintain a healthy balance in nature.

In the mid-1990s, an effort began to reintroduce gray wolves to Yellowstone National Park. The project brought 41 wolves from Canada to the park. The wolves reproduced and became the basis of a Yellowstone-based population that has numbered as many as 120 and in December 2024 was estimated at 108.

The return of wolves has not only drawn visitors hoping to see these beautiful and powerful predators, but their return has also triggered what scholars call a โ€œtrophic cascade,โ€ in which the wolves decrease elk numbers, which in turn has allowed willow and aspen trees to survive to maturity and restore dense groves of vegetation across the park.

Increased vegetation in turn led to beaver population increases as well as ecosystem changes brought by their water management and engineering skills. Songbirds also came back, now that they could find shade and shelter in trees near water and food sources.

Black bear protection in the Great Smoky Mountains

Great Smoky Mountains National Park is the most biologically diverse park in the country, with over 19,000 species documented and another 80,000 to 100,000 species believed to be present. However, the forests of the Appalachian Mountains were nearly completely clear-cut in the late 1800s and early 20th century, during the early era of the logging industry in the region.

Because their habitat was destroyed, and because they were hunted, black bears were nearly eradicated. By 1934, when Great Smoky Mountains National Park was designated, there were only an estimated 100 bears left in the region. Under the parkโ€™s protection, the population rebounded to an estimated 1,900 bears in and around the park in 2025.

Much like the gray wolves in Yellowstone, bears are essential to the health of this ecosystem by preying on other animals, scavenging carcasses and dispersing seeds.

Water preservation in the Everglades

The Everglades are a vast subtropical ecosystem located in southern Florida. They provide drinking water and irrigation to millions of people across the state, help control storm flooding and are home to dozens of federally threatened and endangered species such as the Florida panther and American alligator.

When Everglades National Park was created in 1947, it was the first time a U.S. national park had been established to protect a natural resource for more than just its scenic value.

As agriculture and surrounding urban development continue to pollute this natural resource, park professionals and partner organizations have focused on improving habitat restoration, both for the wildlife and for humansโ€™ water quality.

Inspiring future generations

To us, perhaps the most important work in the national parks involves young people. Research shows that visiting, exploring and understanding the parks and their ecosystems can foster deep connections with natural spaces and encourage younger generations to take up the mantle of stewardship of the parks and the environment as a whole.

With their help, the parks โ€“ and the landscapes, resources and beauty they protectโ€“ can be preserved for the benefit of nature and humans, in the parks and far beyond their boundaries.

The #YampaRiver is a recreation hotspot, but #SteamboatSprings can close it during summer’s peak — Alex Hager (KUNC.com)

Tubers float down the Yampa River in Steamboat Springs on July 23, 2025. A stretch of the river running near downtown can see more than 20,000 tubers through the course of the summer, but city officials sometimes roll out recreational shutdowns to protect the Yampa’s fish. Alex Hager/KUNC

August 5, 2025

This story is part of ongoing coverage of water in the West produced by KUNC and supported by the Walton Family Foundation.

On a hot summer day in Steamboat Springs, the Yampa River feels like the beating heart of the city. On a recent July afternoon, its banks teemed with people looking for a cool refuge from the mid-80s temperatures and direct sun.

Local mom Alohi Madrigal was one of them. She and two friends watched their kids jump off the rocks into the Yampaโ€™s clear water. A steady stream of relaxed-looking tubers floated by too, sprawled out on thick, yellow inflatables.

Even at 3 p.m. on a Wednesday, this little section of the Yampa looked like a postcard-perfect picture of a summer vacation in the Colorado mountains.

โ€œIt’s totally amazing,โ€ Madrigal said. โ€œIt’s beautiful. It’s gorgeous.โ€

โ€œAnd free,โ€ one of her friends chimed in.

But days like this are a precious commodity in Steamboat Springs. When it gets too hot, the city shuts down this specific stretch of river: a roughly six-and-a-half-mile section that flows through downtown, just steps away from the shops and restaurants. During the driest years, it can be bereft of swimmers, tubers and anglers for weeks at a time.

This year, it was already closed for four days in July, and may close again before the summer is through.

Itโ€™s part of an uneasy balance struck by Steamboat Springs. The Yampa is the cityโ€™s lifeblood. Its water irrigates nearby farms and ranches. The same river supplies drinking water to homes and businesses all over town. During the summer, it becomes a mecca for vacationers who flock to the resort town for a cool mountain escape. The city estimates that more than 21,000 people took tubes down this stretch of river in 2024.

But itโ€™s also home to fish. When the river is hot and low, too many humans in the water can setress out its fish โ€“ causing lasting damage to their health or even killing them. That could create an unpleasant scene for all of those river users and throw the Yampaโ€™s ecosystem out of whack.

As a result, the city enforces periodic shutdowns to keep the river healthy, even if it means people โ€“ and businesses that can make big bucks on equipment rentals โ€“ will have to avoid it on the days when its cool water beckons the most.

Flows for fish

Itโ€™s easy to look at the Yampa and think about the paddlers and floaters playing on its surface. It’s also easy to forget about the silent, scaly residents beneath. But those fish are at the heart of the riverโ€™s summer closures.

โ€œIt pretty much all comes down to fish health,โ€ said Emily Burke, conservation program manager at the nonprofit Friends of the Yampa. โ€œFish get super stressed when river temperatures reach a certain level.โ€

Recreational closures on the Yampa can be triggered by three things: low water levels, high water temperature or low levels of dissolved oxygen in the water. All three make it harder for fish to survive.

When the river gets low and hot, fish often donโ€™t have enough oxygen to breathe, causing them to get exhausted. That could make them too tired to look for food or stop eating. Already stressed and drained of energy, the extra stress added by humans in the river can cause lasting harm to fish health and โ€” in some cases โ€” kill them.

โ€œIf you have a bunch of people splashing around in these deep pools [that] these fish are using as refuge,โ€ Burke said, โ€œIt’s really stressful for them, and it can sometimes lead to fish die-offs.โ€

Measuring stations along the river gather data about its water every fifteen minutes. If the water is hotter than 75 degrees for two consecutive days or flowing lower than 85 cubic feet per second, city officials will roll out a river closure.

โ€˜A huge economic driverโ€™

When the Yampa is teetering on the edge of a shutdown, the people watching closest are often those whose businesses depend on it. Johnny Spillane is one of them. He owns Steamboat Flyfisher, which has a back patio that overhangs the river itself.

On a recent Thursday morning, as people milled in and out of brunch spots and started heading toward tourist activities, Spillane stood behind the counter of his store.

โ€œYou can tell in the shop right now it’s pretty quiet,โ€ Spillane said. โ€œIf it was a busy, hopping day with people fishing in town, it would be a lot busier right now.โ€

The river was still open for swimming, tubing and paddling, but officially shut down for fishing.

โ€œJuly days are our most important days as a business, so losing July days certainly hurts a little bit more,โ€ Spillane said. โ€œBut at the same time, you know, losing the fish in the river would hurt a lot more than that. For us, protecting the fish, protecting the resource, is far much more important than getting an extra couple days of fishing on the town stretch, or selling a couple dozen extra flies.โ€

Johnny Spillane, owner of Steamboat Flyfisher, poses in his shop on July 24, 2025. “Protecting the fish,” he said, “protecting the resource, is far much more important than getting an extra couple days of fishing on the town stretch, or selling a couple dozen extra flies.โ€ Alex Hager/KUNC

Spillane said the river closure doesnโ€™t affect his business that much. Fewer people come into the store to buy equipment, but the shopโ€™s fishing guides โ€” who can run more than 200 trips each week โ€” can take customers 20-30 minutes outside of town to other streams, rivers and lakes that are open for anglers.

Even owners of businesses that are inextricably tied to the Yampaโ€™s โ€œtown stretchโ€ share Spillaneโ€™s mentality.

Backdoor Sports sits just a short walk downstream from the flyfishing shop. Itโ€™s a powerhouse in the local tube renting scene. Backdoor moves so many rental tubes โ€“ as many as 400 a day during the peak of summer โ€“ that it has a drive-thru-style window to keep customers moving from signup to river in short order. The shop dispatches rental tubes from a literal backdoor, which lies no more than a couple dozen feet from the Yampa.

Stacks of inflatable tubes wait for renters at Backdoor Sports in Steamboat Springs on July 23, 2025. “The closures can be tough at times,” said Mike Welch, the shop’s owner, “But also necessary, because it’s good to protect what we have here.” Alex Hager/KUNC

โ€œThe Yampa River is a huge economic driver for the city,โ€ said Mike Welch, a co-owner of Backdoor. โ€œWe want to make sure that it stays that way for a lot of years to come. The closures can be tough at times, but also necessary, because it’s good to protect what we have here. It’s a wonderful, wonderful thing that we’ve got.โ€

While it takes some extra preparation to steel Backdoor against changing river conditions and shutdowns, Welch said communication from city officials makes it easier.

โ€œThe city has done a great job in setting those parameters,โ€ he said. โ€œSo we know what the water is looking like and where and when those closures are potentially coming. So we can plan for it.โ€

Welch bought the business alongside his brother and sister-in-law this spring. The previous owner, Pete Van De Carr, was a well-known local who died in February following a skiing accident.

Another shop owner, Marty Smith, said Van De Carr played a part in getting the city to specify its plans for reopening the river after a closure.

โ€œEvery day, all the outfitters in town, we would get emails from Pete saying we need to come up with a rule to reopen the river,โ€ said Smith, owner of Mountain Sports Kayak School. โ€œI think that they definitely listened to Pete.โ€

City officials say they are trying to be more transparent about the criteria they use to reopen the Yampa for recreation and communicate directly with outfitters about upcoming changes to closures. The city consults with Colorado Parks and Wildlife before reopening the river. They consider current river conditions, weather forecasts and the amount of stress that fish may already be feeling from hot, dry conditions.

โ€˜A tough spot to be inโ€™

For the city officials who manage closures on the Yampa, itโ€™s all about balance.

โ€œWe hate having to do this,โ€ said Jenny Carey, the cityโ€™s Open Space and Trails supervisor, โ€œBecause you inevitably will hear from somebody that it’s just ruining their day, their business. And that’s tough. That’s a tough spot to be in. We don’t want to do that.โ€

Carey said Steamboat Springs puts up signs and social media posts to inform people about the closures and the reasons for them.

โ€œWe understand that people want to be in the river,โ€ she said, โ€œAnd so it’s a difficult conversation. We do our best to educate as best we can. I think a lot of our locals are getting used to this, and they understand the reason.โ€

While it can be rocky trying to tell out-of-town tourists that they wonโ€™t be able to tube on a hot summer day, locals really do seem to be getting the message. In a 2024 survey of Steamboat Springs residents, 92% of people said โ€œmanagement of the health of the Yampa Riverโ€ was essential or very important.

Thatโ€™s only five points lower than the fire department. Managing the Yampaโ€™s health ranked as more important than city parks and the police department.

โ€œThe Yampa river is considered one of the most important services that the city provides,โ€ said Julie Baxter, the cityโ€™s water resources manager. โ€œSo we feel very grounded that we have the support of the local community members that live here in Steamboat Springs.โ€

Recreational closures on the Yampa are mandatory for rental shops, but technically voluntary for individuals who want to bring their own tubes or kayaks. But with so many locals on board, few people decide to take a dip.

โ€œIf there is a closure in place and you get in the river,โ€ Baxter said with a chuckle, โ€œYou will likely have a local yell at you.โ€

Alohi Madrigal, who was raised in Steamboat Springs and still lives in town, watched her kids splash in a stretch of the Yampa that may be closed later this summer. She said a shutdown wouldnโ€™t be the end of the world.

โ€œThere’s a million things to do here,โ€ she said, proceeding to list off a handful of other swimming spots. โ€œWe have to take care of the river, or it won’t be here for long.โ€

The well-lived life of John Stulp — Allen Best (BigPivots.com)

August 5, 2025

Colorado governors of the past and possibly the future gathered in Lamar to pay their respects. His last wishes were that the wheat harvest go on.

When it became clear that John Stulp had little time left to live, he specified that the memorial service would come later, after the wheat had been harvested but before the next planting.

That service was held on Saturday, August 2, at the First Baptist Church in Lamar, in southeastern Colorado, not quite a month after his death. Several hundred people attended, many of us from out of town.

Fittingly, the family had positioned a few large vases fill with bundles of wheat next to the photos of Stulp. One photo was Yuma High School, and another was from a meeting with then-President Jimmy Carter. He got around in his life, but in his heart, he remained a farmer.

Tributes to his life were lavished at the church in Lamar, and from my experiences with him during the last 13 years or so, they were deserved. Responding to my first impressions on Facebook, one individual said this: โ€œA great man.โ€ Said another: โ€œThese sorts of people make civilization work.โ€

Former Colorado Gov. Bill Ritter was at the remembrance in Lamar, as was an individual who may possibly become Coloradoโ€™s next governor, Phil Weiser. Neither spoke, and as for Weiser, I saw no evidence he was campaigning. It appeared to me he was simply there to pay his respects after likely arising early in [Denver] to get to Lamar by mid-morning.

This was in addition to former U.S. senator, Ken Salazar, who was in the audience along with Kate Greenberg, the current Colorado commissioner of agriculture, and two of her predecessors, Don Brown and John Salazar. I also recognized various people from the Colorado Water Conservation Board, including at least two former directors of the Colorado Water Conservation Board, Becky Mitchell and James Eklund.

John Hickenlooper, still another former Colorado governor, was not there but had delivered a eulogy from the floor of the Senate shortly after Johnโ€™s death on July 7. โ€œJohn was a good man, a great man by any measure,โ€ Hickenlooper had said.

What came out again and again was his love of place, his devotion to family and community, his generous heart. And while he was also a notably good listener, it was also said that John was a very good storyteller.

I knew Stulp a bit. In about 2012, I went to Beaver Creek for a water forum, and he was a speaker. I struck up a conversation with him, and he invited me to visit him on his farm south of Lamar the following weekend. Then I didnโ€™t fully realize the irony of his position as the stateโ€™s โ€œwater czarโ€ for Hickenlooper: his farm south of Lamar was entirely dryland.

When I visited him at that farm, we talked at length before he showed me around his home country. We stayed in touch after that, usually it being a matter of me seeking his perspective about water, energy, and other matters.

John leaned into the future. He saw the tiny details and the big pictures. Several times I consulted him to understand the role of eastern Colorado in our stateโ€™s energy transition. He had been a Prowers County commissioner from 1992 to 2003, and during the latter time he voted for approval of Colorado Green. The wind farm south of Lamar was, when it began operations in 2004, the largest in the country.

Of late, I was particularly interested in his experience as an early adopter. In his electric pickup he made the rounds between Lamar, a home in Lakewood that I believe he and his wife, Jane, had acquired during his 12 years in his position in Colorado state government, and Yuma, where he had begun life during an intense snowstorm in 1948 and where he still had farming property. Trips often also included Fort Collins, where two of his children lived.

See: Electric pickups and farm country

Earlier this year, I was curious whether the growing network of fast-charging stations in eastern Colorado was meeting his traveling needs. By then, he was on oxygen, eight liters a minute, and when in the pickup he needed to draw on the battery. That gave him less margin for error, he said, and no, Coloradoโ€™s fast-charging infrastructure on the eastern plains fell short. He had been forced to return to an internal-combustion engine for trips to the Front Range.

As recently as late June, I had written to him after noticing a letter from him filed in a Colorado Public Utilities docket. It was, I wrote to him truthfully, the most compelling of all the comments I had seen filed in that case.

The main reflection I had after hearing the remarks in Lamar was a reinforcement of my previous opinion. For whatever reason, John put it together early in life. Many of us struggle to figure out our paths. He did not. He must have been a bright boy. By age 4, he was accompanying his aunt to a one-room schoolhouse. He grew up farming, growing corn, and raising cattle and hogs. He went to Colorado State University and became a veterinarian.

After stints as a veterinarian in Windsor and then Las Cruces, N.M., he and his wife, Jane, moved to the Lamar area, where she had grown up on a farm. They had five children, and he assumed new roles in agriculture organizations, his community, and state and national organizations. He was on the board of directors for the State Land Board, for the Colorado Wildlife Commission, and the board of governors of Colorado State University.

In the 1990s, then Colorado Gov. Roy Romer twice asked him to be the state ag commissioner, but he declined, citing the need to be with his family. Bill Ritter made the same request when he was elected in 2006, and this time he excitedly said yes. He served a four-year term.

Governor Hickenlooper, John Salazar and John Stulp at the 2012 Drought Conference

When John Hickenlooper was elected governor in 2010, he asked Stulp to be part of his team but in a different capacity. In his eulogy on the floor of the Senate, Hickenlooper explained what he was up to. Colorado had experienced particularly severe drought in 2011 and even more in 2012.

โ€œI was convinced that we needed a blueprint, a plan of some sort, to address the projected growth and its future water supply, to make sure that we had the supply that could match our needs. I recruited John to serve as my top water policy advisor. We made it a cabinet-level position. He came to all our cabinet meetings. He was our water czar.โ€

Stulpโ€™s background in agriculture โ€” which uses 85% to 90% of water in Colorado โ€” was key to his choice.

โ€œJohn understood the agriculture community in Colorado better than almost anyone,โ€ explained Hickenlooper. โ€œMaybe thatโ€™s why, when I first approached him with the idea of a statewide water plan, he wasnโ€™t immediately convinced. Actually, he was far from it. He was, I would say, more than skeptical.โ€

Hickenlooper explained that he understood how difficult it would be to get buy-in. โ€œHe didnโ€™t think it was a smart idea for me politically as a new governor to take on an issue that had the potential to be so divisive,โ€ explained Hickenlooper. โ€œBut he understood that we couldnโ€™t let our rivers and farms be at risk of running dry. We needed him. Colorado needed him. And he set aside his reservations, rolled up his sleeves and went to work.โ€

Stulpโ€™s work in achieving consensus was part of the state water plan completed in 2015 (and since updated twice). What has been the result of that plan? Has it actually been a success? Thatโ€™s a much longer story.

In his eulogy, Hickenlooper also added a personal touch.

โ€œIโ€™m not sure there are gradations of โ€˜goodness,โ€™ but I have traveled long distances with John Stulp, and Iโ€™ve stayed at his home in Prowers County where he and his remarkable wife, Jane, would cook up a barbecue and get me together with some of their neighbors.โ€ โ€œHe even loaned my son, Teddy, a .410 shotgun so he could learn how to shoot,โ€ said Hickenlooper.

โ€œIf I did believe in gradations of โ€˜goodness,โ€™ John and Jane Stulp would be at the very top.โ€

Delivering a testament later, once again in response to my Facebook post, was Jackie Brown, who spent 39 yeas in public health, including 22 years in Prowers County. Stulp had recruited her to the position from nearby Baca County.

โ€œJohn was the best example of a good man and a great leader,โ€ she wrote. โ€œHe was honest, smart, caring, fair and had integrity. His family, community and his employees were his priority. Plus, he had a great sense of humor.โ€

The service was held in a church, and it turns out that Stulp was deeply religious. During covid, after his work in Colorado state government, he was confined to his home. He had, he told me, been admonished by one of his sons for venturing out to Walmart. Later, he lost a brother in Yuma to covid.

In this time of isolation, John agreed to take over the Baptist ministerโ€™s daily phone tree that sought to connect people during times of isolation. The pastor, Darren Stroh, said that Stulp had sent more than 200 messages. One of them contained these thoughts:

โ€œIf you were judged โ€” choose understanding.

If you were rejected โ€” choose acceptance.

If you were shamed โ€” choose compassion.

Be the person you needed when you were hurting, not the person who hurt you.

Vow to be better than what broke you -โ€” to heal instead of becoming bitter.

Act from your heart โ€” not your pain.โ€

At the church on Saturday, his son Jensen told us about the father he knew, the father who relished wheat harvest, where he loved to offer rides in a combine to his grandchildren and others. Harvest on July 4th always produces extra energy amid questions of will it rain and will there be time to watch fireworks.

On this yearโ€™s July 4th, days before he died, the Stulp family gathered around John. With his strength ebbing, he delivered โ€œone of the most meaningful and powerful speeches weโ€™ve ever heard,โ€ said John Stulp III. โ€œIt was a charge to the grandkids. First thing he said, finish harvest. Keep cutting the wheat. That was said multiple times.โ€

Then he continued about how he wanted them to comport themselves. Be flexible. The world is better when you are generous. We produce food, and the world is hungry. Care for others. Make sure they know you love them. Jesus wasnโ€™t petty; neither should you be. Live in this moment and live it to the fullest, but plan for the future.

And with those words to his grandchildren remembered we were invited to the fellowship hall and a long table of tasty home-cooked food and an equally long table of desserts. In the middle of each table was a centerpiece consisting of a mementoes of Johnโ€™s life and a small bundle of wheat.

Toxicity: The Invisible Tsunami — Deep Science Ventures

Click the link to access the report on the Deep Science Ventures website:

How pervasive toxicity threatensย  human and planetary survival

What if one of the biggest threats to our health and planet is invisible, yet found in our air, food, and water?

Our latest report is the first time that a single report has attempted to analyse the broader collective problem and solution spaces of chemical toxicity answering the questions: how and why are toxic chemicals produced, how do they get into our bodies and the environment, and how do they affect the health of humans and other organisms?

Over eight months, we conducted an extensive analysis, including reviewing countless peer-reviewed studies and 50+ interviews with global experts. This research shows that the impacts of chemical toxicity are largely underestimated, contributing to increasing cancer rates, declining fertility, and a surge in chronic diseases, alongside ecosystem damage.

The overarching conclusion is that chemical toxicity is an underestimated risk to society and deserves significantly more attention and resources. 

But this report isn’t just about the problem; it’s a call to action for solutions. We highlight critical industry, regulatory gaps and, most importantly, identify key areas for innovation and urgent funding that can put us on the right path to increase our understanding and make positive changes where it’s most needed.

We identified three opportunity areas that demand solutions: pesticides (herbicides and insecticide), food contact materials, personal care products.

Key takeaways include:

  • Over 3,600 synthetic chemicals from food contact materials are found within human bodies globally.
  • PFAS have contaminated the entire world, with levels in rainwater often exceeding safe drinking water limits.
  • Over 90% of the global population is exposed to air pollution exceeding World Health Organisation (WHO) guidelines.
  • The impact of pesticide use on cancer incidence may rival that of smoking and is linked to leukaemia, non-Hodgkinโ€™s lymphoma, bladder, colon, and liver cancer. Prenatal pesticide exposure increases the odds of childhood leukemia and lymphoma by over 50%.

#Colorado Parks & Wildlife is developing a #Beaverย (Castor canadensis)ย Conservation and Management Strategy: Public scoping through August 31, 2025

Click the link to go to the Colorado Parks & Wildlife Engage CPW website for all the inside skinny:

CPW is developing a Beaver (Castor canadensis) Conservation and Management Strategy. The public scoping period is now open through August 31, 2025. Please provide feedback through the comment form on this page. A recorded presentation with more information is available under Important Links.

Background and Need

As a keystone species, beavers provide essential ecosystem services and increase local biodiversity in ecologically suitable habitats. However, beavers also represent a source of human-wildlife conflict, particularly at the interface of human infrastructure and waterways. 

Increasing interest in beavers as an agent for ecological restoration prompted Colorado Parks and Wildlife (CPW) to begin developing formal guidance to inform beaver conservation and management, including such topics as: harvest regulation, restoration, techniques for coexisting with beaver, and relocation. Given the broad reach, complexity, and interrelatedness of these topics, CPW is gathering input from diverse stakeholders to inform a strategy for beaver conservation and management.

How to Get Involved

The public scoping period will be open from July 30 through August 31, 2025. A scoping feedback form will be available at the bottom of this page once the input period opens.

Public input on the draft Beaver Conservation and Management Strategy will be open in Fall 2025.

As Gross Reservoir rises, Boulder County residents grapple with projectโ€™s legal turmoil — The Water Desk #BoulderCreek

July 23, 2025

Pieter Strauss used to love hosting stargazing parties at his house in the Lakeshore Park neighborhood up Flagstaff Road southwest of Boulder. The hobbyist astronomer would fire up the barbecue and spend hours showing his neighbors the night sky through his observatory and telescopes. 

Straussโ€™s house sits looking directly over Gross Reservoir, which provides water to Denver residents.

But when a project to significantly raise the reservoirโ€™s dam began construction in 2022, those moments of neighborhood tranquility were lost for some residents. For Strauss the biggest impact was the bright construction lights used to keep work moving overnight. 

โ€œIt became impossible to sit on the deck before sunrise and after sundown, astrophotography was impossible. They lit up the skies,โ€ with powerful floodlights, Strauss said. 

For over 20 years, residents and various environmental groups have protested the project, which suffered a series of legal blows this year. Construction on the massive dam ground to a halt in April amidst the courtroom wrangling, and subsequent decisions have cast a new level of uncertainty over large-scale water projects that propose to draw on the beleaguered Colorado River.  

However, by the end of May, federal courts ruled that construction could continue due to concerns surrounding uncompleted construction and potential flooding possibilities, but that the reservoir could not be filled. 

The Gross Reservoir Expansion Project involves raising the height of the existing dam by 131 feet. The dam will be built out and will have โ€œstepsโ€ made of roller-compacted concrete to reach the new height. Image credit: Denver Water

Raising the dam 

Gross Reservoirโ€™s dam is owned and operated by Denver Water. The utility built it in the 1950s, with two other building phases planned to accommodate future water needs. The current dam expansion will raise the height of the dam 131 feet, tripling the current capacity of the reservoir, and providing more water for Denver Water customers. 

The construction was spurred by โ€œa combination of demands in our system, as well as concerns about climate and concerns about the needs for greater resilience in our system,โ€ said Jessica Brody, general counsel for Denver Water. 

The need for the expansion is similar to a bank savings account, Brody said. Tripling the capacity of the reservoir is a savings account that can be drawn on in circumstances of an emergency.

โ€œIf we have an extreme drought event, we want to have more water banks that we can help smooth the impacts to our customers,โ€ Brody said. 

When the utility initially announced plans to begin moving forward with a dam expansion, residents of the area were concerned. Environmental threats and the disruptions from the massive construction project topped the list of worries. They attended meetings at town halls with county commissioners. They organized with other residents in and around Coal Creek canyon.

While some residents fought the expansion, others anticipated it. When the dam was initially constructed, the utility planned to expand further down the line. 

Since construction began in 2022, residents have experienced noise and light pollution. Five neighbors have moved from the Lakeshore Park neighborhood. Pieter Strauss, at whose house they once held stargazing gatherings, was among them.

โ€œThe most valuable thing to all the people who have moved up here is that they had a quiet nature sanctuary. But then when you take that away, is it worth it?โ€ said Anna McDermott, another resident of the area. 

โ€œWe sleep with our windows open. Not one house has air conditioning, so you sleep with your windows open in the summer months,โ€ she said.  โ€œYou hear these giant backup beepers crashing, grinding all night long. Even with earplugs, I canโ€™t sleep.โ€ 

The Environmental Group (TEG) is an organization of residents in the Lakeshore Park neighborhood and surrounding residents, focused on engaging the community in action when environmental issues arise. Along with Save the Colorado, The Sierra Club, and other environmental organizations, TEG has fought the expansion. Beverly Kurtz, former president of TEG, has worked to hold Denver Water and the companies working on the dam, Kiewit Corp. and Barnard Construction Company Inc., accountable during construction. 

Heavy duty trucks are required to use a different road to access the dam rather than the paved road up Flagstaff Mountain due to fire concerns. Large semi-trucks have slid off the road due to the steep grade, which can cause traffic jams and road closures. 

โ€œAt one point they had one of the two roads down this mountain closed for five months,โ€ Kurtz said. โ€œIt wasnโ€™t until we called the sheriff out here and he realized the safety concern that they opened the road back up.โ€

Legal snares slow construction

In October 2024, two years after construction began, Save the Colorado, along with other environmental groups, won a lawsuit against Denver Water. U.S. District Court judge Christine Arguello found the utilityโ€™s dam construction permit violated the Clean Water Act and the National Environmental Policy Act. At the time, construction was able to continue and Arguello ordered the groups to work out an agreement regarding damages. 

In April 2025, the judge ordered a temporary halt on construction. The initial lawsuit argued that the U.S. Army Corps of Engineers, who provided the project permitting, did not fully consider climate change impacts when it approved the damโ€™s expansion. 

A month later, Arguello ruled that Denver Water could finish construction on raising the dam, but that the reservoir could not be filled until the Army Corps reissued the permits.

โ€œIf you stop the construction of a dam when it is partially built, the dam doesnโ€™t function as it was ultimately designed to function,โ€ said Denver Waterโ€™s Brody. โ€œThat was a big concern of ours and the Federal Energy Regulatory Commission.โ€

The utility has also been ordered to not remove any additional trees surrounding the dam until the proper permits are obtained. The project proposes the removal of over 200,000 trees. 

Arguelloโ€™s opinion also called into question the underlying water rights Denver Water would rely on to fill the newly enlarged reservoir when construction finished. Gross Reservoir is filled with water from the headwaters of the Colorado River, which has experienced steep declines in water supply amid a long-term warming and drying trend in the Rocky Mountains. 

โ€œThe Environmental Impact Statement didnโ€™t even look at the fact that the flows of the Colorado River are in decline. Most of the science suggests they will continue to decline further,โ€ said Doug Kenney, Western Water Policy Program director at the University of Colorado Boulderโ€™s Natural Resources Law Center. Acquiring new permits will require Denver Water to redefine the projectโ€™s purpose and evaluate the environmental damage, he said.

The case is more than a local water project. Diverting more water across the western slope of Colorado has created concerns for ecosystems throughout the overappropriated watershed and for communities downstream in California, Nevada and Arizona. 

โ€œIt makes it more difficult to ensure that thereโ€™s sufficient flow downstream as a result,โ€ Kenney said. โ€œWe have got to stop this practice of taking more and more water out of the upper reaches of the Colorado River because it just increases the stress on a river that is already under a tremendous amount of stress.โ€

By calling into question the projectโ€™s potential to have downstream impacts, the decision could add a new legal hurdle future water development infrastructure will have to clear. 

โ€œHistorically, agencies in recent decades have not done enough to consider climate change in decisions,โ€ Kenney said. Cases like this one need to happen in natural resource law more generally, he said, as they help establish precedents for future projects that could potentially put the environment at risk. 

Denver Water is appealing the court decisions that bar the expansion. That could result in a reissue of the permits with a redefined purpose or a dismissal of the court rulings made earlier this year. 

โ€œWe think that the district court made some misjudgements or misinterpretations when it found the Army Corps committed these errors,โ€ Brody said. 

Learning to live alongside it

Amid the stops and starts of Gross Reservoir construction, nearby residents are not ready to let go of what they used to have. 

Kurtz and McDermott recall their old activities along the reservoirโ€™s north shore. A handful of neighbors would walk their dogs everyday along the hiking trail that connected the reservoir to their neighborhood. The trail has since been widened significantly, to allow for excavating equipment. They would host Memorial Day parties along the waterโ€™s edge.ย

Now they minimize their excursions to the shore as much as they can. At this point theyโ€™re more than ready for construction to be completed, exhausted from the daily disruptions, explosions and drilling. 

โ€œNow clearly, when the work is done, the things which negatively impacted my life would go away. But I couldnโ€™t last them out,โ€ Strauss said. He recently relocated to the Boulder area. โ€œIt was just my bad luck that my golden years coincided with the worst effects of the project.โ€ 

Some residents found that the expansion project has renewed their sense of community in Lakeshore Park.

โ€œIn a weird way a lot of us have gotten even closer because we were in the battle together,โ€ Kurtz said. โ€œWe feel like at this point we won the battle, but weโ€™ve lost the war.โ€

โ€œThey will get the permits to eventually fill this reservoir following the expansion,โ€ she said. 

However, federal courts requiring the proper permits to continue construction is a win in her and TEGโ€™s book, as it sets a precedent for any large construction processes that occur in the future. It will ensure that the proper environmental permits are obtained before construction can begin on a project. 

โ€œIf nothing else, we hope that precedent still stands. Because it will help somebody else,โ€ she said.

Navajo Nation pushes for water rights as #ColoradoRiver shrinks — The St. George News #COriver #aridification

July 29, 2025

Bidtah N. Becker, chief legal counsel for the Navajo Nation, told St. George News there is an urgency to secure the tribe’s legal rights to the Colorado River in Arizona, calling it their “No. 1 issue.” Becker explained that while the tribe secured water rights settlements in Utah in 2022 and in New Mexico in 2009, members still lack a legal water allocation in Arizona. A proposed bill in Congress, the Northeastern Arizona Indian Water Rights Settlement Act of 2025, seeks to address this gap. The billย involves partnerships with the Hopi Tribe, the San Juan Southern Paiute Tribe, the state of Arizona and more than 30 municipalities and communities in northern Arizona…The legislation has been delayed due to a lack of agreement from the seven Colorado River Basin states, which are focused on post-2026 guidelines for managing the river. Becker said the Navajo Nation remains hopeful that once those discussions advance, a settlement can gain momentum…

The Navajo Indian Irrigation Project, located in northwest New Mexico, draws its water from Navajo Lake on the San Juan River and moves it through more than 70 miles of main canals and 340 miles of laterals. Approved by Congress in 1962, the project transformed from a small-scale farming initiative into a major agricultural operation. The project holds rights to 508,000 acre-feet of San Juan River water annually, used to irrigate high desert lands south of Farmington, New Mexico…

Beyond agriculture, the Navajo Nation is working to secure municipal water supplies. Becker said one key project underway is the Navajo-Gallup Water Supply Project. A lateral portion of the project, running along U.S. Route 550, is already constructed; the second lateral section still requires funding to be completed.

A judge has sided with a Western Slope water district in a dispute with Denver Water over a problem dam in Grand County.

In its 2021 complaint, Denver Water accused the Colorado River Water Conservation District of breach of contract by slow walking required repairs to Ritschard Dam until Denver Water became part owner of the dam in 2020, at which time the Front Range water provider would share financial responsibility for repairs. 

But in a June 19 judgment, District Court Judge Mary C. Hoak found in favor of the River District, writing that the River District made thoughtful, prudent and reasonable decisions with respect to repairs to Ritschard Dam, and did not act dishonestly or outside of accepted practices.

โ€œOur partner in that reservoir turned around and sued us, in my mind, because they wanted a different contract over how the dam is managed and they wanted to weasel out of their obligation to pay for the repair and rehabilitation, should it ever be required,โ€ said River District General Manager Andy Mueller at the River District boardโ€™s regular meeting Tuesday. โ€œThe judge saw through their smokescreen and really rewarded the district for doing the right thing.โ€

The River District is now asking that Denver Water pay nearly $773,000 in costs associated with the lawsuit. 

In an emailed statement, Denver Water spokesperson Todd Hartman said the water provider โ€œcontinue(s) to assess the ruling and consider potential next steps.โ€

Wolford Mountain Reservoir. An aerial view of Wolford Reservoir, formed by Ritschard Dam. An aerial view of Wolford Reservoir, formed by Ritschard Dam. The reservoir is managed by the River District and Denver Water owns 40% of the reservoir capacity.

The complaint stemmed from structural issues at Ritschard Dam, which forms Wolford Mountain Reservoir on the Muddy Creek upstream of the town of Kremmling. Built in 1995, the reservoir has a capacity of 66,000 acre-feet, and Denver Water releases water from it downstream to offset its upstream diversions at Dillon Reservoir and the Roberts Tunnel. Denver Water, which is Coloradoโ€™s oldest and largest water provider serving about 1.5 million people, helped finance construction of the dam and reservoir, paying about $43 million.

The River District owns and operates the 122-foot-tall dam and reservoir, and according to agreements between the two entities, Denver Water would lease 40% of the reservoir capacity from when the reservoir was completed in 1995 until 2020. At the end of 2020, Denver Water would take 40% ownership of the reservoir capacity along with 40% ownership of the water right. 

Denver Water would also become responsible for 45.33% of the costs of operation, maintenance and rehabilitation of the dam, which had been solely the River Districtโ€™s financial responsibility up until that point. 

Because of the disagreement, the two entities extended the lease agreement until summer 2021. At that point, according to Mueller, the River District conveyed a deed to Denver Water, which then became part owner, and the water provider has been paying for its share of the operation, maintenance and repair costs during the litigation.

Settling and cracking

In 2009, the River District became aware of settling and deformation of the dam, meaning the structure is moving more than expected, and has been intensely monitoring the situation since then. From 2012 to 2015, the River District began moving toward structural rehabilitation, but a 2015 expert review panel found there was not a need for immediate remediation. 

In 2019 and 2020, cracks appeared in the dam, prompting further study and dam safety evaluations. From 2013 to 2022, the River District spent $3.7 million on dam-related maintenance and dam-deformation expenses. 

Denver Water argued the River District led Denver Water to believe that the River District would make repairs to the dam, but then changed its mind just prior to the expiration of the lease agreement, after which Denver Water would be on the hook for its share of the cost of repairs. Denver Water argued that instead of repairing the dam as required, the River District hired new experts and reversed course.  

Jim Lochhead, who was Denver Water CEO from 2010 to 2023, testified at a 12-day trial in May 2024 that Denver Water didnโ€™t know until an August 2019 meeting that the River District wasnโ€™t going to repair the dam. But the court disagreed, citing evidence Denver Water knew of the River Districtโ€™s plans as of February 2017 at the latest.

โ€œโ€ฆthe Court does not find Mr. Lochheadโ€™s testimony on this point credible,โ€ the judgment reads. โ€œMr. Lochhead was the only witness that testified at trial regarding this meeting, there are no documents supporting the occurrence or substance of this meeting, and Denver Waterโ€™s Complaint, Denver Waterโ€™s Notice of Breach and discovery responses do not reference this meeting.โ€

In addition to expert testimony and documents, the courtโ€™s judgement relied on the annual inspection reports for Ritschard Dam from the Colorado Division of Water Resources State Engineerโ€™s Office, which have rated the dam โ€œconditionally satisfactoryโ€ since 2012 and never ordered a storage restriction. 

โ€œThe SEO annual inspection reports were uniformly positive as to the maintenance of the dam,โ€ the ruling reads. 

โ€œ(Denver Water) had an elaborate scheme cooked up in their heads that this board and staff management, as well as the past management, concocted some way to delay things and did it in bad faith,โ€ Mueller told the River District board. โ€œThey told a story to the court that they completely failed to support with any facts at the court level, and we won on all claims.โ€

The River District win comes at a pivotal time for Colorado water managers that underscores the simmering tension that remains between the West Slope and Front Range. Denver Water, along with other Front Range water providers, has been granted a special hearing in September to air their concerns about the River Districtโ€™s plan to purchase water rights tied to the Shoshone hydropower plant in Glenwood Canyon. 

Although this chapter of litigation is over โ€” Denver Water has a right to appeal โ€” the problems with the Ritschard Dam remain. The dam is classified as high hazard, which means dam failure is expected to result in loss of human life. The River District board allocated more money to address the structural issues at its regular meeting Wednesday, approving a $294,185 contract with HDR Engineering, Inc. for an alternatives analysis to evaluate potential modifications to the dam. The alternatives analysis was recommended in a 2024 Comprehensive Dam Safety Evaluation. 

โ€œWeโ€™re not out of the woods on that dam, so we just have to continue to put public safety as the number one priority of the district, and use that as our guiding principle,โ€ Mueller said.

…in his second administration, President Donald Trump is not just approaching climate science with skepticism. Instead, his administration is moving to destroy the methods by which his or any future administration can respond to climate change. These moves, which are sure to be challenged in court, extend far beyond Trumpโ€™s well-documented antipathy toward solar and wind energy and his pledges to drill ever more oil even though the US is already the worldโ€™s largest oil producer. His Environmental Protection Agencyย announced plans this weekย to declare that greenhouse gas emissions do not endanger humans, a move meant to pull the rug out from under nearly all environmental regulation related to the climate. But thatโ€™s just one data point. There are many others:

  • Instead of continuing a push away from coal, the Trump administration wants to do a U-turn; Trump has signed executive orders intended to boost the coal industry and has ordered the EPA to end federal limits on coal- and gas-fired power-plant pollution thatโ€™s been tied to climate change.
  • Tax credits for electric vehicles persisted during Trumpโ€™s first term before they were expanded during Joe Bidenโ€™s presidency. Now, Republicans areย abruptly ending themย next month.
  • The administration is also ending Biden-era US government incentives to bring renewable energy projects online, a move that actually appears to be driving up the cost of electricity.
  • Republicans in Congress and Trumpย enacted legislationย to strip California of its authority to ban the sale of new gas-powered vehicles beginning in 2035.
  • Trump is also expected to overturn national tailpipe standards enacted under Bidenโ€™s EPA and is alsoย to challengeย Californiaโ€™s long-held power to regulate tailpipe emissions.
  • The authors of a congressionally mandated report on climate change were all fired; previous versions of the report, theย National Climate Assessment, which showed likely effects from climate change across the country, have been hidden from view on government websites.
  • Other countries, large and small, will gather in Brazil later this year for a consequential meeting on how the world should respond to climate change. Rather than play a leading role โ€” or any role at all โ€” the US will not attend.
  • Cuts to the federal workforce directly targeted offices and employeesย focused on climate change.

The Southern Ute tribe has finally tapped #LakeNighthorse water. Why did it take 60 years? — Shannon Mullane (Fresh Water News) #AnimasRiver

July 31, 2025

This summer, the Southern Ute Indian Tribe rolled out miles of temporary rubber water lines. The above-ground tubes had one job: carrying water to oil and gas operations on the reservation.

But the pipelines also represent something else: a historic moment in a drawn-out, arduous debate over water in southwestern Colorado.

In May, the Southern Ute Indian Tribe tapped into its water in the controversial Animas-La Plata Project, the first time a tribe has used its water from the project since it was authorized in 1968.

The Animas-La Plata Project has come to encapsulate long-held dreams to develop Western water โ€” and the decades of debates, environmental concerns, local objections and Congressional maneuvering that almost made the project fail.

At the center of it all were tribal nations and the chance to, once and for all, settle all of the tribal water claims in Colorado. It took until 2011 to fill Lake Nighthorse, the main feature of a heavily scaled-down federal water project located just south of Durango. Then 14 more years for a tribe to be able to use a small slice of its water.

More barriers โ€” tied to interstate laws, finances and infrastructure โ€” still stand in the way of tribes and other Animas-La Plata water users taking full advantage of the multimillion-dollar project. 

โ€œThis has taken the hard work of many Tribal leaders and Tribal staff over many decades to get to where we are at now,โ€ the Southern Ute Indian Tribe said in a prepared statement.

All Animas-La Plata Project water users can access water both in the reservoir, Lake Nighthorse, and the Animas River, but they draw from the river first. The reservoir functions like a savings account, said Russ Howard, the general manager for the Animas-La Plata Project.

This year, the tribe used water from the Animas River for oil and gas well completion activities, which wrapped up in mid-July. The tribe declined to provide more details.

It plans to use the revenue from the project to upgrade dilapidated irrigation systems, like the deteriorating federal Pine River Indian Irrigation Project, or other water-related projects, like infrastructure to access its Animas-La Plata Project water.

The Southern Ute Indian Tribe and its sister tribe in Colorado, the Ute Mountain Ute Tribe, have repeatedly brought up their lack of access to the Animas-La Plata Project in high-level conversations about tribal water access in the broader Colorado River Basin and how to manage the basinโ€™s overstressed water supplies once key management rules expire in 2026.

The Colorado River Basin is the lifeblood of the American Southwest, providing water to 40 million people, cities from Denver to Los Angeles, industries and a multibillion-dollar agriculture industry. The Colorado Riverโ€™s headwaters are in western Colorado, but its water finds its way to faucets, ditches and hoses in every corner of the state.

Tribal nations have federally recognized rights to about 26% of the Colorado Riverโ€™s average flow between 2000 and 2018. Butย theyโ€™re not using all of this water. In some cases, theyโ€™re still going through legal processes to finalize their rights. In others, they are working on finding funding for new pipes, reservoirs and canals to access their water.

In some cases, downstream water users have become reliant on water while tribes are sorting out their water rights. But tribes say they are actively working on ways to put their water to use, which could push nontribal water users down the priority list.

โ€œThe Tribe wants everyone to understand that there currently is a reliance on undeveloped tribal water,โ€ the Southern Ute statement said. โ€œIt is important for everyone to understand that the Southern Ute Indian Tribe has the right to develop its water resources and plans to do so.โ€

A big dream for the Southwest

People have been crafting different versions of an Animas-La Plata Project since at least 1904.

In the 1970s, they were drawing up maps showing a dam across the Animas River, also called El Rรญo de las รnimas Perdidas or the River of Lost Souls, to create the Howardsville Reservoir north of Durango. Other new reservoirs, plus hundreds of miles of canals and ditches, would provide irrigation water for both Native and non-Native farmers. The โ€œAnimas Mountain Reservoirโ€ would provide drinking water for Durango. There would be plenty of water for irrigation, municipal and industrial users in the Southwest.

It was the age of water development in the West, led by the U.S. Bureau of Reclamation, and anything seemed possible.

Only, none of that happened.

Thatโ€™s according to piles of manila folders, labeled in scrawling cursive, in the archives at Fort Lewis Collegeโ€™s Center of Southwest Studies. There, thousands of pages of documents reveal how, exactly, the big dream fell apart and a small, but vital, version survived.

In the 1960s, lawmakers, like Colorado Democrat Wayne Aspinall, fought in Congress to get the Animas-La Plata Project into the Colorado River Basin Project Act of 1968.

Congress authorized the project alongside others in the Upper Colorado River Basin, like the Dolores Project in southwestern Colorado, and Lower Basin goals, like the Central Arizona Project. They were supposed to be developed on the same timeline to avoid showing favoritism to one basin or another.

The Central Arizona Project came online and started sending water to growing cities, like Phoenix. The Dolores Project launched to help farmers and ranchers.

But the Animas-La Plata Project remained snared in issue after issue.

Decades of challenges

In the 1980s, the Southern Ute and Ute Mountain Ute tribes saw the Animas-La Plata Project as a way to settle their water rights in Colorado.

They agreed to stop 15 years of water-related lawsuits against the federal government โ€” and to give up water rights claims in other local streams โ€” in exchange for the Animas-La Plata Project and the tribal water rights that came with it.

The idea turned into the Colorado Ute Indian Water Rights Final Settlement Agreement of 1986. Getting the agreement approved by Congress, however, took two years.

Some farmers supported it: If the tribes pursued their powerful water rights on the streams, their claims would likely have priority over nontribal farmers, meaning they might not get as much water in drier years. And people in the dry Southwest needed the stability of guaranteed water storage.

Drought conditions have at times forced the Ute Mountain Ute Tribe Farm & Ranch Enterprise in southwest Colorado to operate on a fraction of the water needed to grow crops, resulting in dormant fields and irrigation systems. On a day in late May [2022] when wildfire smoke obscured the throat of an ancient volcano called Shiprock in the distance, I visited the Ute Mountain Ute farming and ranching operation in the southwestern corner of Colorado.

Rafting companies feared a project would hurt business. Environmentalists said it was one of the last free-flowing rivers in the Colorado River Basin. It didnโ€™t make sense to pump water out of the Animas, over a hill and into a valley to create a reservoir, they said. That valley held protected elk habitat. It also included waste material from uranium mining. (This was eventually removed in a remediation project.)

For years, local groups fought the projectโ€™s costs, the electricity its pumps would require and the burden more irrigation water use would put on the Animas.

โ€œIโ€™ll actually tell you a little bit about it,โ€ said Lew Matis, one of the volunteers organizing railroad photos in the Center of Southwest Studies on a Wednesday in July. โ€œI was involved with the taxpayers against the Animas Project.โ€

Matis, a self-described โ€œold fart of old Fort Lewis,โ€ even wrote to The Durango Herald in the 1980s, saying the $586.5 million price tag was โ€œapproaching pie-in-the-sky aspects.โ€

Then there was the classic Colorado River tug-of-war between the Lower Basin and the Upper Basin: The Upper Basin tribes wanted to be able to lease their water off-reservation. Lower Basin states, like Arizona, California and Nevada, said it would conflict with state and interstate laws. Theyโ€™d kill legislation that included leasing. Tribal officials said the states didnโ€™t want to have to pay for tribal water they were already getting for free.

(Whether and how tribes can lease water between the Lower Basin and Upper Basin is still an issue today. It was one of the central problems that held up a $5 billion Arizona-tribal settlement that is languishing in Congress.)

Tribal officials traveled to Washington, D.C., to push for the settlement to pass.

โ€œIโ€™ve been moving this Animas-La Plata Project through, the people say well itโ€™s not going to get funded,โ€ said Leonard Burch, former Southern Ute Chairman, in an interview from the 1980s. โ€œBut we insist.โ€

A big dream and a (much) smaller reality

By 1988, Congress approved the settlement agreement with the Animas-La Plata Project at its center.

It solved all the tribal water rights claims in Colorado in one go, something that states like Arizona are still trying to do. The Ute Mountain Ute Tribe, which also has land in New Mexico and Utah, is still working to finalize some of its water claims.

Then U.S. Rep. Ben Nighthorse Campbell, in a press release from 1988, likened the settlement to โ€œwinning a gold medal.โ€ (And he would know. Campbell won a gold medal in judo in the 1963 Pan-American Games.)

Then, in the early 1990s, the U.S. Fish and Wildlife Service found an endangered fish species, the Colorado pikeminnow, downstream from the potential project site. And the Animas-La Plata Project started to crumble.

The Colorado pikeminnow, renamed to remove a slur, can grow to nearly 6 feet in length and was the main predator in the Colorado River system. But by the late 20th century, it occupied about 25% of its natural range, and federal wildlife officials said dams and river depletions were one of its biggest threats.

The findings opened the door to questions about impacts to other species, like peregrine falcons, rare plants, bald eagles and razorback suckers.

The federal government started to question whether the projectโ€™s costs matched the benefits. The U.S. Bureau of Reclamationโ€™s fervor for enormous Western water projects had waned, and former President Bill Clintonโ€™s administration did not support the larger version of the Animas-La Plata Project authorized in the 1960s.

That project would have cost $744 million and built two reservoirs, 240 miles of pipelines and canals, seven water-pumping plants and 34 miles of electric transmission lines, according to local news coverage from the โ€™90s. It would also require the careful collection and removal of hundreds of years of cultural artifacts from different Native American bands, which was done for the final project.

After years of intense political maneuvering and fighting among all sides, Congress finally approved the final project: a dam to create a reservoir in Ridges Basin โ€” now called Lake Nighthorse โ€” and a pumping plant and pipes to suck up Animas River water and push it into the reservoir.

The La Plata River, which would have received Animas River water in the original version (hence its name), was left alone. The irrigation water โ€” part of the original goal of the project โ€” was removed from the agreement. The size of the dam shrank to 217 feet from 313 feet above the streambed. Congress dropped reservoirs and delivery pipelines for tribes. The final cost estimates ranged from $250 million to $340 million.

Looking at a description of the project from the 1980s, the projectโ€™s current manager Howard said hardly any of the plan actually happened.

โ€œItโ€™s unfortunate. That was the vision. Everybody was excited, and everybody supported what it was trying to do,โ€ he said. โ€œBut ultimately, we ended up with a very, very small portion of what youโ€™re showing in that document.โ€

โ€œA whole bunch of work leftโ€ 

The final Animas-La Plata Project did achieve some of its original goals.

It settled water rights in Colorado for the Southern Ute and Ute Mountain Ute tribes.  It included about 132,000 acre-feet of water and a new recreation spot for locals. Officials responded to environmental concerns (although some may still argue that point). It secured municipal and industrial water for the Navajo Nation near Shiprock, three New Mexico communities, Durango and rural residents in the Southwest. And tribes had funding to help them develop their water resources.

But โ€œthereโ€™s a whole bunch of work left to do,โ€ Howard said.

So far, four of the 11 entities that have water rights in the Animas-La Plata Project have been able to put that water to use, he said. The Southern Ute Tribal Council approved the use of up to 2,000 acre-feet annually of its Animas-La Plata Project water, according to the tribeโ€™s statement.

โ€œItโ€™s long overdue,โ€ said Becky Mitchell, the stateโ€™s commissioner to the Upper Colorado River Commission. She has advocated for tribes in Colorado River negotiations. โ€œTheyโ€™ve been trying to get access and infrastructure help and be able to access water that they have rights to. This is a step in that direction.โ€

The Ute Mountain Ute Indian Tribe, which is located farther from the Animas River and Lake Nighthorse, is still looking for ways to access its water. Whether that is new, expensive infrastructure โ€” pipes and reservoirs that were formerly included in the Animas-La Plata Project โ€” or other options is still to be determined.

Simple geography is one of the biggest barriers in using their project water, said Peter Ortego, a long-time lawyer for the Ute Mountain Ute Tribe.

The Animas-La Plata Project is right next to the Colorado-New Mexico border, but it must be used within Colorado. The tribes have too much municipal water for the areaโ€™s population, and too much industrial water for the potential mining uses so close to the border. Hydraulic fracturing, the main oil and gas water use, doesnโ€™t use much, he said.

โ€œWhen it comes to the health of the Tribeโ€™s water system, I think taking the irrigation out of that was really bad,โ€ Ortego said. โ€œIt hurt the farmers. It hurt the Tribe.โ€

The Ute Mountain Ute Tribe took a major step forward in December when they finalized their repayment contract with provisions that make it easier to participate in conservation projects and to afford the federal operations and maintenance fees that are triggered upon first water use, he said.

Ben Nighthorse Campbell, now 92 and living about 25 miles from the reservoir that bears his name, still thinks the project was a success. He remembers the bitter fights with environmentalists, recalling a passing car with a bumper sticker that said, โ€œDonโ€™t dam the Animas, damn Campbell.โ€

When the project finally passed, it passed overwhelmingly, and that was the thing the opposition hated most of all, he said.

โ€œI donโ€™t like to be vindictive, but I felt like, โ€˜Gotcha, you bastards,โ€™โ€ Campbell said in an interview with The Colorado Sun. โ€œIt became kind of personal, you know? They threw so many barbs at me, so many shots, and I was just ready to fight back.โ€

Colorado has come a long way, but going forward, water managers need to focus on more ways to reuse water, said Campbell, who also served as Coloradoโ€™s U.S. Senator.

โ€œWeโ€™ve got to find better ways of using what we have. Not producing more water that doesnโ€™t exist,โ€ he said.

July 31, 2025

State officials may have solved the puzzle of how zebra mussels got into the Colorado River. 

On July 3, Colorado Parks and Wildlife officials discovered a large number of adult zebra mussels in a privately owned body of water in western Eagle County. On Monday, Madeline Baker, an invasive species specialist with CPW, told members of the Colorado Basin Roundtable they believe this private lake is an upstream source of the mussels that have contaminated the Colorado River, the Government Highline Canal, Highline Lake and Mack Mesa Lake. 

โ€œWe do believe this to be the primary source, but it could now have created other secondary sources downstream with locations that hold water,โ€ Baker said. โ€œThere is a lot of speculation of could these veligers survive the journey from Eagle County down to Highline and create a new population there or is there some sort of intermediate population in between. So we still have a lot to figure out.โ€

Baker said that the lakeโ€™s owner is collaborating with CPW on a mitigation plan. CPW is not releasing the ownerโ€™s name or specific location of the lake.

โ€œThe property owner is unsure of how this could have happened, but is being cooperative,โ€ she said.

Baker said there were quite a few dead shells on the shoreline of the private lake, which indicates the zebra mussel population has been there for several years. She said CPW staff found the lake by searching Google maps for bodies of water on private property near the Colorado River and then calling property owners and asking if they could inspect their lakes. An outlet from the lake was bringing zebra-mussel-infested water into the Colorado River, an issue that has since been fixed. 

โ€œWeโ€™ve done a dye test at the reservoir to be sure that nothing more is flowing into the river, and that dye test showed us that it should be contained at this point, which will allow us to pave a path toward mitigation,โ€ Baker said.

Zebra mussels are a prolific invasive species that if left unchecked could clog irrigation infrastructure, and strip the plankton and nutrients from the water. Once established, they are nearly impossible to eradicate. 

For the last two summers, microscopic zebra mussel larvae, known as veligers, have been found in the Colorado River at several locations. In June, they were found at the boat launch in New Castle, in Highline Lake and Mack Mesa Lake. The Colorado River is now considered โ€œpositiveโ€ for zebra mussels from the confluence with the Roaring Fork River to the Colorado-Utah border.

Threat to the Grand Valley

The arrival of zebra mussels has been especially alarming for the Grand Valley, which is one of the most important agricultural areas and home to the biggest agricultural water users of Colorado River water on the Western Slope.

โ€œAt least from a Grand Valley perspective, we feel like we are under a very serious threat,โ€ said Kirsten Kurath, a Grand Valley attorney and vice-chair of the roundtable.

Adult mussels were found in 2022 in Highline Lake near the Utah state line. Officials treated it with a form of copper that kills zebra mussels called EarthTec QZ and drained it for the 2024 boating season. The lake reopened for recreation this year but on June 10, CPW staff found more veligers in Highline Lake, which is now designated an infested body of water. Highline Lake is filled with water from the Government Highline Canal, which pulls water from the Colorado River.

โ€œWe now know that Highline Lake was continuously being reinfested with mussels after the treatment, so itโ€™s difficult to ascertain the effectiveness of the treatment,โ€ Baker said.

Veligers were also found last year in the Government Highline Canal, which brings water from the Colorado River to Grand Valley farms, vineyards and orchards. Realizing the mussels could be disastrous for commercial peach growers who use micro-drip irrigation, water managers sprang into action last fall, treating their systems with a copper solution that kills the mussels.

Grand Valley Water Users Association General Manager Tina Bergonzini said the copper treatment was successful โ€” the irrigation company has not seen any signs of adult mussels in their system โ€” and the Government Highline Canal has not had any more positive tests for veligers. Still, Bergonzini said GVWUA will probably do the copper treatment again this fall, and that preventing zebra mussels from becoming established is something they will be working on for the foreseeable future.

โ€œI donโ€™t think there is any way around [doing the copper treatment again],โ€ Bergonzini said. โ€œWe canโ€™t risk our infrastructure. Itโ€™s a financial hurdle for the irrigation companies because itโ€™s very costly, but not as costly as having fouled infrastructure.โ€

The discovery of the source pond in Eagle County is a step in the right direction, but it doesnโ€™t mean the fight against zebra mussels is over. CPW will continue sampling and mitigation work, Baker said.

โ€œFinding the source was always the main focus,โ€ Bergonzini said. โ€œThereโ€™s no way you can win the war if you canโ€™t figure out where they are coming from. So I think discovering that pond was huge. That gives us a really good chance.โ€

CPW says cleaning, draining and drying fishing gear, motorized boats and hand-launched vessels like paddle boards is key to preventing the spread of invasive species.

#Drought intensifies and spreads: Also: Introducing Data Center Watch, alfalfa exports fall, federal agency trolling — Jonathan P. Thompson (LandDesk.org)

๐Ÿฅต Aridification Watch ๐Ÿซ

The monsoon is on its way, apparently, but seems to be delivering more lightning than rain to many areas that are grappling with wildfires. Meanwhile, the drought is intensifying and spreading in almost all parts of the West, especially in the deep Southwest. 

Streamflows are dropping, too. The Animas River in Durango has fallen to about 200 cubic feet per second, and itโ€™s only at about half that by the time it gets to Farmington, New Mexicoโ€™s, new surfing wave. The Rio Grande already dried up in Albuquerque a couple of weeks ago (but got a good boost from a thunderstorm early this morning). WyoFile reports that the Snake, Wind, and Bear Rivers are all at record low flows for this date, even though the snowpack was about average this winter. 

And, of course, the wildfires continue to burn. The Dragon Bravo Fire on the Grand Canyonโ€™s North Rim has burned through 112,000 acres so far, with only 9% containment. The Monroe Canyon Fire in southwestern Utah is at 55,642 acres with 7% containment, and is causing power outages in surrounding communities. The Turner Gulch Fire northeast of Gateway is still growing โ€œdue to continuous hot and dry conditions and erratic winds.โ€ And the Elkhorn Fire north of Durango has settled down a bit at 317 acres, but officials worry forecasted hot and dry conditions could reawaken it.

Below are some satellite moisture index maps, with blue being moist and red indicating dryness. The top image shows Dove Creek and areas south of there. This was dryland farming country for many years (Pinto Bean Capital of the World), but irrigation from McPhee Reservoir on the Dolores River was later extended out to Dove Creek. Problem is, their water rights are junior to the farmers in the Montezuma Valley near Cortez, so when reservoir levels are low, they tend to get less irrigation water. Here you can see the difference between 2023 (on the left), when snow, river, and reservoir levels were high, and this year (right), when they are not. What stands out to me is that some fields are still being irrigated this year, despite the drought, as is indicated by the circles of bright blue. But there are more fallow fields now, and the areas around the fields are especially dry.

Here are two more images showing the Ute Mountain Ute Tribeโ€™s farms south of Ute Mountain in 2023 compared to 2025. Again, some irrigation is still reaching the fields, but apparently far less, given the number of fields that are apparently fallow.

The Land Desk is adding another beat to its roster, the Data Center Watch, which is just to say that Iโ€™ll be covering data centers and their economic and environmental ramifications a bit more frequently from here on out. Why? Because they currently are proliferating throughout the West: There are 93 data centers in the Phoenix area, 54 in the greater Denver area, and eight in Albuquerque, with many more on their way. And every one of them uses outsized quantities of electricity and water, straining power grids, and throwing utilitiesโ€™ resource planning into disarray.

Cheyenne, Wyoming, is already home to six data centers. That doesnโ€™t count Metaโ€™s $800 million center that is under construction there, or energy firm Tallgrassโ€™s proposed facility that would pull 1,800 megawatts of electricity from new, dedicated natural gas plants and renewable power installations (presumably solar and wind). Down in Tucson, city officials are considering Amazon Web Servicesโ€™ proposed Project Blue, a massive complex that is poised to consume up to 2,000 acre-feet of water per year and become Tucson Electric Powerโ€™s largest single customer.

In Alaska, a company is looking to build a large data center and a dedicated natural gas plant that would run off of oilfield methane. Numerous data centers can be found along the banks of the Columbia River, drawn there in part by the relatively cheap and abundant hydropower. In Montana, a proposed data center would use all of the powergenerated by NorthWestern Energyโ€™s existing resources. And Pacific Gas & Electric expects new data centers in Silicon Valley to drive a 10 GW increase in electricity demand over the next decade, which is about one-third of todayโ€™s forecast peak demand for Californiaโ€™s grid.

The biggest concern with these sprawling warehouses packed with processors is their power consumption. Each one can draw as much electricity as a small city โ€” the proposed Cheyenne server farm would use more power than all of the stateโ€™s households. As recently as half a decade ago, most utilities werenโ€™t expecting the speed and magnitude of the big data center buildout. Now itโ€™s hitting hard, and coinciding with increased demand from a growing number of electric vehicles and electrified homes, and utilities are scrambling to bring new power sources online to meet the projected demand growth. This includes geothermal, wind, and solar power โ€” each with impacts of their own โ€” but also new natural gas plants and even small nuclear reactors. Some utilities are cancelling plans to retire coal plants to keep enough generating capacity online.

In other words, the data center boom is likely to radically reshape the energy landscape of the West, and will spur more debates over the costs of this sort of economic development and the impacts our cyber-world has on the environment and humanity.

๐Ÿ“ˆ Data Dump ๐Ÿ“Š

In some ways, I guess you could say that as alfalfa is to the Colorado River, data centers are to the Western power grid: they both suck up a lot of the resources. That doesnโ€™t make them bad. Alfalfa mostly goes to dairy cows, which make cheese and ice cream and other really good things. Data centers power annoying AI art, sure, but they also make everything internet possible, including me sending this newsletter to you.

Anyway, itโ€™s worth tracking both โ€” alfalfa and data centers, I mean. So hereโ€™s a quick update on hay exports from the U.S. (which includes alfalfa and other hay), as well as a look at acreage planted in alfalfa (excl. other hay) over time. Exports seem to have peaked in 2022 and are now in decline. Nevertheless, sending alfalfa and other hay overseas is big business.


๐Ÿคฏ Annals of Inanity ๐Ÿคก

You might think that our federal agencies under Trump would be content to wreck the environment and trample civil liberties in a quiet, not-so-noticeable way. But no, of course not: Theyโ€™re so proud of their racism and fetishization of fossil fuels that they plaster social media with their proclamations thereof โ€” they are trolling us, in other words. 

Above are just two recent examples. In the first one, the Department of Energy fawns over a sparkling chunk of coal. In the other, the Department of Homeland Security posts an 1872 painting by John Gast titled โ€œAmerican Progress.โ€

Both are gross in their own way.

What the hell kind of sexualization of coal โ€” i.e. โ€œShe is the momentโ€ โ€” are they going for in that first one? Frigginโ€™ perverts, if you ask me.

As for the second, it glorifies the crimes the American military and white colonial settlers perpetrated against the Indigenous peoples in order to get more Lebensraum, one might say (it makes sense to use Hitlerโ€™s term given that he was inspired by the U.S.โ€™s policies toward Native Americans). Not only is the use of the word โ€œHeritageโ€ in this way a dog whistle to white supremacists, but itโ€™s also kind of weird to be talking about defending the โ€œHomelandโ€ against immigrants when, in the image, the immigrant invaders are the white settlers, and the folks trying to defend themselves and their homeland are the Indigenous people (and wildlife) fleeing from the settlers.

#Drought news: Parachute adopts Water #Conservation Program in lieu of changing conditions at #ParachuteCreek — The PostIndependent.com

West Drought Monitor map July 29, 2025.

Click the link to read the article on the Glenwood Springs Post-Independent website (Town of Parachute):

July 30, 2025

n July, the Parachute Town Council adopted a Water Restriction and Conservation Program to help the town respond quickly and responsibly to changing water conditions.ย 

The new program allows the town to implement or lift water use restrictions as needed throughout the year, based on water availability, drought conditions and regional coordination. 

On July 15, it was announced that Parachute remains at a Stage 1 Water Watch due to low flows on the Parachute Creek. It has remained at Stage 1 partially due to ongoing coordination with other users of Parachute Creek and the communityโ€™s ongoing conservation efforts. 

Stage 1 is a voluntary stage that applies to raw water irrigation users only. Parachute has not implemented any mandatory restrictions at this time and potable drinking water customers are not affected. 

Parachute is encouraging all irrigation water users to take simple voluntary actions to help conserve water, such as:

  • Reducing outdoor watering to three to five days a week
  • Watering in the early morning or late evening to reduce evaporation
  • Focusing water use on trees, vegetables and essential landscaping only
  • Avoiding overwatering lawns or irrigating during rainfall

Voluntary conservation is key, as cutting back now could help the community avoid stricter, mandatory restrictions later this summer.

If conditions change, additional stages of the program may be implemented. Higher stages could make the current voluntary measures enforceable or even lead to a ban on all outdoor irrigation, though that has not yet been necessary in Parachute.

Future restrictions will be announced publicly and community members can stay up to date by following the town of Parachuteโ€™s social media accounts, like their Facebook at facebook.com/townofparachute/, downloading the โ€œTown of Parachuteโ€ mobile app or visiting the townโ€™s utilities page at parachute.gov/o/top/page/utilities

#Colorado Basin Roundtable takeaways: Less snowmelt, less water, and zebra mussels — KJCT

Colorado River May 2023 swelled from low elevation snow runoff.

Click the link to read the article on the KJCT website. Here’s an excerpt:

July 28, 2025

On Monday, the Colorado Basin Roundtable had a meeting to discuss the state of the Colorado River. The Roundtable discussed the potential Shoshone stream flow acquisition. The area of interest is the 2.4 miles in Glenwood Canyon. It is important for Western Colorado because of its stream flow rate that mimics the current water rates used for hydropower. Wildlife organizations did habitat studies on it, and they show it improves the natural environment.

Another topic of discussion was the basin hydrology. With a limited snowpack this year, there is less water. The biggest concerns people had in the meeting related to that was the stress of many systems struggling from prolonged drought and aging infrastructure. Lindsay DeFrates, Deputy Director of Communications for the Colorado River District, said, โ€œThe Colorado Basin Roundtable is a great example of a room where a bunch of different stakeholders from agriculture, recreation, environment, municipal, industrial, water users all come together to talk about those solutions. Itโ€™s never an easy conversation. And we canโ€™t forget about zebra mussels. Zebra mussel veligers were found at the Silt Boat Ramp and near New Castle.

July 25, 2025

The governments of Mexico and the United States signed a memorandum of understanding on Thursday [July 24, 2025] to fund and expedite several wastewater treatment projects in the Tijuana River basin. Untreated wastewater continually affects residents living along the river, which flows across the border from Tijuana and through several of San Diegoโ€™s southern neighborhoods. Residents living along the river have long battledย severe health issuesย which researchers say stem from the riverโ€™s contamination. One research team based at the University of California San Diego found that trace amounts of waterborne chemicals from tires, personal care products, and even illicit drugs present in the Tijuana Riverย are being introduced into the airย โ€” exacerbating health concerns for tens of thousands of residents living on its banks…

In Thursdayโ€™s event celebrated in Mexico City, US Environmental Protection Agency Secretary Lee Zeldin and Mexicoโ€™s Secretary of the Environment and National Resources of Mexico Alicia Bรกrcena agreed to a series of actions to be taken by both governments by 2027 to address the deteriorating wastewater treatment crisis. The agreement stipulates that both Mexico and the US will re-commit to funding the construction and renovation of water treatment infrastructure on both sides of the border. The document also accelerates several projects to be completed over the next two years…Former Commissioner of the International Water and Boundary Commission (IBWC) Maria-Elena Giner called the agreement โ€œexcellent newsโ€ toward reaffirming commitments made by the US and Mexican officials in Minute 328, which outlines how Mexico and the US will share the costs of operating and maintaining water treatment infrastructure on the border.

This is the final part of a series about four groundwater basins in Colorado. The story was commissioned byย Water Education Coloradoย and benefited from editing by Caitlin that organizationโ€™s staff. It appears in a variant form in theย summer 2025 issue of Headwaters magazine.ย 

The San Luis Valley, like the Republican River Basin, has almost no tax base other than irrigated agriculture. โ€œNearly everything in the valley is somehow related to agriculture. Our hospital, our schools โ€” everything is dependent on agricultureโ€™s existence in the valley,โ€ says Amber Pacheco from her office in Alamosa. From her office in Wray, Deb Daniel has a parallel observation.

What then constitutes sustainability of the water that is the foundation of agriculture or, in the case of Parker, Castle Rock, and other south metro communities, their economic vitality? What decisions should be made now to foster that vitality through the 21st century?

Smuggler Mine back in the day via GregRulon.com

Thoughts about conservation have shifted over time. When Coloradoโ€™s gold and silver miners arrived, they had no goal of conserving. They either mined the veins to exhaustion, or it became too costly to continue. In a sense, that has happened in the Republican River Basin. The only limits to this groundwater mining are those triggered by the interstate compact. Because the Republican River and its tributaries get most of their water from aquifers, pumping must be limited โ€” or supplemented.

In the last 20 years, the Republican River Water Conservation District has done some of both. It has or soon will have committed $86 million to pump water from wells expressly to deliver water to the Nebraska state line. One of the directors, Tim Pautler, has called this a strategy of kicking the can down the road. Other directors have started to agree.

โ€œItโ€™s like the clock is ticking when it comes to sustainability,โ€ said Rod Lenz, the board chair, at the boardโ€™s quarterly meeting in May 2025. โ€œWhat more can we do with the tools we have? Do we dare ask for more tools such [as would be delivered by] statute changes? Do we really want all the groundwater districts in the basin to ask the state engineer to reconsider how much weโ€™re allowed to pump, or do we just stay in compliance until we canโ€™t?โ€

San Luis Valley Groundwater

In the San Luis Valley, coming off the century-defining drought of 2002, state legislators went in exactly the opposite direction. They said that the unconfined aquifer was to be managed sustainably. Granted, thatโ€™s easier said if you have a major river flowing nearby, even if that river has been hammered hard by the warming, drying climate of the 21st century.

Water stored in Coloradoโ€™s Denver Basin aquifers, which extend from Greeley to Colorado Springs, and from Golden to the Eastern Plains near Limon, does not naturally recharge from rain and snow and is therefore carefully regulated. Courtesy U.S. Geological Survey.

The south metro area falls somewhere between these two extremes. State legislators nearly a half-century ago ordered a โ€œslow sipโ€ of the groundwater such as to preserve it for a century. In some places, there seems to be sufficient water to slow sip for another 300 years. In other places, the aquifer might have enough water for a few decades. Some water utilities hope for a completely sustainable water supply in decades ahead. Much work has been done. The harder work lies yet ahead.

What we need are aspirations premised not on entitlement and enrichments solely for today, but instead to build economies and cultures that more comprehensively look several generations ahead. That should be the question in all these meetings, all these court cases, all of these individual actions. Based on what we know and understand today, what should we be doing for the kids, grandkids and their grandkids, too? Are we doing better than kicking the can down the road?

Romancing the River We Have โ€“ sort ofโ€ฆ. — George Sibley (SibleysRivers.com) #ColoradoRiver #COriver #aridification

July 30, 2025

We left the Colorado River a couple months ago to explore the Trumpstersโ€™ effort to use the public lands in the river basin to โ€˜unleash American energyโ€™ and return us to the glorious age of cheap petroleum โ€“ and why itโ€™s not happening. At that time, the seven states in the riverโ€™s basin were in a stalemate over a management plan to replace the cobbled together โ€˜interimโ€™ management guidelines that expire next year. The Trumpstersโ€™ have not interceded noticeably in this situation, since it appears to require complex and sustained thought.

Unfortunately, the stalemate is still the basic situation. As a couple water mavens put it, weโ€™re all still waiting for the black smoke coming out of the chimney to turn white. The Basinโ€™s state representatives are meeting together regularly though, with input from the First People, and reports from the meetings suggest that the participants have all agreed to โ€˜work with the river we have, not the river we wish we (still) hadโ€™ (if we ever actually did have it) โ€“ the Colorado River Compactโ€™s river. So a little review here today, to remind us where this puts usโ€ฆ.

Carpenter (Colorado), Herbert Hoover (Secretary of Commerce and Chairman of Commission), R. E. Caldwell (Utah), Clarence C. Stetson (Executive Secretary of Commission), Stephen B. Davis, Jr. (New Mexico), Frank C. Emerson (Wyoming), W. F. McClure (California), and James G. Scrugham (Nevada) CREDIT: COLORADO STATE UNIVERSITY WATER RESOURCES ARCHIVE via Aspen Journalism

The Colorado River Compact was created in 1922 for a river that had been, for a couple decades, running flows guesstimated to average 18 million acre-feet (maf) annually. The compact commissioners thought they were being conservative in only dividing 15 maf among themselves, and assumed that โ€˜those men who may come after us, possessed of a far greater fund of informationโ€™ would be dividing up even more water after resolving a share for Mexico and resolution of the Indian rights.

The river then played desert trickster and stopped running those big flows, shortly after Congress passed the Boulder Canyon Act to reconstruct the Colorado River through the subtropical deserts below the canyons. By the end of the 1930s drought that followed, the statesโ€™ water leaders knew the numbers in the Compact division might have been for a river that no longer existed, if it ever really had. But they persisted with the Compact, in the spirit of the unnamed quasi-mythical G.W. Bush administration official: โ€˜We are an empire now, and when we act, we create our own reality.โ€™ The next half century was invested in creating our own imperial reality for the Colorado River โ€“ until we began to run into more โ€˜naturalโ€™ realities than weโ€™d anticipatedโ€ฆ.

The unimperial reality today is a river whose annual flow since the turn of the century has dropped to an average around 12.5 million acre-feet (maf), two-thirds the size of the Compactโ€™s river. That is โ€˜the river we haveโ€™ โ€“ and we are aware of the extent to which our superimposed imperial reality on the Colorado River region (and on the whole planet) has caused a lot of this unanticipated loss of water.

Exactly what it means when the basin-wide negotiators say they are working with that โ€˜river we haveโ€™ has not been revealed. One bad sign, however, viewing it from โ€˜outside the box,โ€™ is their persistence in thinking of the river as divided into a four-state Upper Basin and a three-state Lower Basin, a construct destined by a competitive appropriation culture to devolve into chronic conflict โ€“ which it has.

Much of the conflict has revolved around the foggily written Article III(d) of the Compact, stating that the Upper Basin โ€˜will not cause the flow of the river at Lee Ferry to be depleted below an aggregate of 75,000,000 acre-feet for any period of ten consecutive years.โ€™ This could be most rationally interpreted as a warning to the Upper Basin to just be careful to not develop to the point of using more than their 7.5 maf/year (which the four states have not even come close to doing) and cutting into the Lower Basinโ€™s 7.5 maf in dry periods. Or it could be irrationally interpreted as a delivery obligation that the Upper Basin had to deliver regardless of the natural state of the river, even if an extended drought forced the upper states to short themselves in order to deliver the required 7.5 maf.

Given a history of tension among the states based on how fast California was growing, the obvious choice between those interpretations was to believe the worst. Their intent in convening the compact commission had been to prevent a โ€˜seven-state horse raceโ€™ to appropriate water for their futures; they wanted a seven-state division of the use of the riverโ€™s water that wouldย override interstate appropriative competition. But they didnโ€™t know enough about either the river or their own fantasy-infused futures to do that desired division. The two-basin division has come to be regarded as a stroke of genius, good for all time, when in fact it was just an expedient measure โ€“ one wouldnโ€™t be wrong to call it a โ€˜desperate measureโ€™ โ€“ to cobble together something that would persuade Congress that the states were enough on the same page so Congress could put up the money for a big control structure (Hoover Dam).

But in their haste in pasting together the two-basin compact, they appeared, through Article III(d), to make one basin โ€˜juniorโ€™ to the other, subject to a โ€˜compact callโ€™ in an extended droughtย ย โ€“ or at least that is how everyone chose to interpret it. The 2007 โ€˜Interim Guidelinesโ€™ began to address that (perceived) inequity by imposing cuts on the Lower Basin states when Mead and Powell Reservoirs dropped to dangerous levels, but on not the Upper Basin (leaving their shortages up to the erratic river). But interstate โ€˜seniorityโ€™ played a big role in the size of cuts for each Lower Basin state, belying the notion that the Compact would protect states from interstate appropriative competition.

So what could todayโ€™s negotiators be doing instead? There is actually a constructive and useful way to divide a desert river into two โ€˜basins,โ€™ based on the nature of the desert river. All rivers are surface water that is leaving โ€“ maybe reluctantly โ€“ the land it flows through; it is leaving the land because the land and its life were not able to put the water to use in support of life or to hold it as groundwater in an aquifer. Even much of the groundwater that doesnโ€™t get used by the plants does not escape leaving the land with the river; isotopic analysis indicates that over the course of a year more than half of all the water in surface streams is groundwater trickling back in.

Ephemeral streams are streams that do not always flow. They are above the groundwater reservoir and appear after precipitation in the area. Via Socratic.org

This is not to say that a river is nothing but a drainage ditch โ€“ an earlier Army Corps of Engineers perspective that messed up a lot of rivers, trying to make the drainage more efficient by straightening channels. All rivers have a much more complex relationship with the land they are flowing through than just โ€˜drainage.โ€™ Most rivers have their origins in highlands โ€“ mountains or other significant uplands โ€“ where steep slopes or fast snowmelts produce too much water to sink into whatever soil there might be; this generates surface flows that become small streams confluing to form larger streams and rivers. Throughย hyporheic exchange,ย surface streams either gain groundwater from the land they flow through when that land has a higher water table than the stream level (aย gaining stream), or they lose water to the riparian areas along the river when the water table there is lower than the stream level (aย losing streamย โ€“ although, since the water it loses nurtures life in the riparian area, I think hydrologists should consider calling it a โ€˜givingย streamโ€™).

For rivers in humid regions, there is adequate precipitation throughout the riverโ€™s basin so the rivers will usually gain more from the land they pass through than they will lose (or โ€˜giveโ€™); they are gaining streams that grow from both surface and ground water until they discharge it all into the seas. But a desert river like the Colorado, on the other hand, is a dependable gaining stream only in its highland headwaters, where the Colorado River accumulates 85-90 percent of its entire water supply from the Southern Rockies, Wind River and Wasatch Mountains above ~8,000 feet elevation. This water-producing region is less than 15 percent of the whole basin. (That โ€˜division contourโ€™ is more accurately an โ€˜ecotone,โ€™ a blurry edge zone, in the 7,500-8,500 feet range.)

Below the ~8,000 foot elevation, the riverโ€™s tributaries flow first into the high orographic โ€˜cold desertsโ€™ (steppes) of western Colorado, southwestern Wyoming and eastern Utah. Most of its tributaries have been โ€˜stepping downโ€™ through the mountain region in a series of canyons alternating with floodplains, all of it the waterโ€™s work โ€“ and all of it the beautiful erosion and deposition that draws and holds us here. As they drop into the high desert, they get into a serious canyon-cutting project through the Colorado Plateau, up to a mile deep โ€“ a mystery story in itself thatย Iโ€™ve written about before. After more than five hundred miles of canyons winding through the Plateau, the river flows out into the subtropical Mojave and Sonora โ€˜hot deserts,โ€™ and thence โ€“ only occasionally now โ€“ emptying whatโ€™s left into the Gulf of California.

Super Bloom along UT-128 during the last road trip with Mrs. Gulch May 2023.

But once they drop out of its headwaters highlands, desert streams and rivers like the Colorado and its tributaries become losing (giving) streams; they get little new precipitation below the ~8,000 foot contour. The occasional exception is the desert cloudburst that manages to penetrate the desertโ€™s heat shield, dumping a huge rain that mostly runs off the desert land in a quick, destructive flood, filling dry arroyos and stream beds for a few dangerous hours. Or a rare winter snowfall that melts and sinks in, activating flora and small fauna that have lain inactive for long periods, instigating pilgrimages from hundreds of miles away just to see the desert in bloom.

The โ€˜naturalโ€™ Colorado River (the river before the 20thย century CE) became a โ€˜big riverโ€™ for two or three months a year, in the May-July period when its mountain snowpack released the majority of the riverโ€™s water into its tributaries and ground storage. But once the snowpack was gone, the natural river became an increasingly modest flow, fed largely by groundwater, and as it wandered through the desert regions, it gave what water it had to riparian life (a process that intensified as humans began โ€˜broadeningโ€™ its riparian areas through irrigation systems), or into desert aquifers โ€“ and a lot of it just evaporated or transpired back into the atmosphere (losses that increased as humans spread more of it out in reservoirs and fields).

There were probably years (like our current water year) in which the last of the natural riverโ€™s water never made it through its lush delta to the sea in the autumn. It is not unusual for a desert stream to completely disappear in its desert; some 40 surface streams and rivers flow into the Great Basin, and most of them just disappear after spreading their limited beneficence en route.

The natural and logical โ€˜two-basinโ€™ division for a desert river like the Colorado, then, would be into a โ€˜water production regionโ€™ and a โ€˜water consumption region.โ€™ With the exception of mountain mining or resort towns, and the mountain flora and fauna, nearly all the users of Colorado River water live below that ~8,000 foot division. They are all in the same boat, trying to figure out how best to share a โ€˜losing riverโ€™ when its flows drop into the desert regions where they live.

The Colorado River Compact ignores this natural division of the river. The clumsy division into the four-state Upper Basin and three-state Lower Basin is done according to state boundaries, which have no geographic or hydrographic relevance to the Colorado River Basin.ย ย The state boundaries also include a lot of heavily developed landย outsideย the natural river basin that can lay claim to Colorado River water as part of the state โ€“ and they have population and wealth concentrations that enable them to move that water out of the basin through tunnels. โ€˜We are an empire, and when we actโ€™ย et cetera et cetera.

The Compact division is especially problematic for the Upper Basin. A quarter to a third of the Upper Basin area is the riverโ€™s major waterย productionย area, scattered among the mountains of the four states above the ~8,000-foot contour, and the rest of the Compactโ€™s Upper Basin is part of the riverโ€™s waterย consumptionย region. The Compact makes no such distinction, and all the water above the Upper-Lower division point near Leeโ€™s Ferry is presumed to be the Upper Basinโ€™s โ€“ minus the annual โ€˜delivery obligationsโ€™ of 7.5 maf for the Lower Basin and half of the 1.5 maf for Mexico. Given that the riverโ€™s annual flows vary between 5 and 20 maf, this makes the Upper Basinโ€™s Compact allotment of 7.5 maf annually a fantasy.

Acknowledging the desert nature of the Colorado River suggests a rather radical, but common sense two-basin management strategy for the Colorado River, addressing two main challenges: first, to work out an equitable division among all users for the use of the water that flows into the โ€˜water consumption regionโ€™; and second, for all water consumption region users to collaborate on optimizing (not โ€˜maximizingโ€™) the flow out of the โ€˜water production regionโ€™ and into the deserts.

And a third challenge (which should be first) would be to transcend (abandon) the Compactโ€™s two-basin division, the artificiality of which just gets in the way of desert-river reality at best, and at worst fosters a competitive rather than collaborative attitude between the two basins.

And thatโ€™s enough for today. We will look more closely at those challenges next time โ€“ unless the negotiators have come up with a brilliant breakthrough to parse out. Donโ€™t hold your breathโ€ฆ.

This Week’s Drought Summary

This U.S. Drought Monitor (USDM) week saw continued improvement in drought-related conditions across areas of the Midwest (Michigan, Ohio, Indiana, Illinois, Iowa, Minnesota), central and northern Plains (Kansas, Nebraska, Dakotas, eastern Montana), South (Texas), and in the Desert Southwest (New Mexico). During the past week, the most significant rainfall accumulations were observed across areas of Kansas, Missouri, Iowa, and Minnesota, where they ranged from 3 to 7+ inches. Elsewhere, short-term precipitation shortfalls (past 30 to 60 days) led to continued expansion of Abnormally Dry (D0) areas across the Southeast states including the Carolinas, Georgia, and Alabama as well as the introduction of isolated areas of Moderate Drought (D1) in Alabama, Georgia, and South Carolina where agriculture-related drought impacts are being reported. In the South, drought conditions continued to improve in western portions of Texas as well as in areas of eastern New Mexico where monsoonal storms have provided some minor relief to areas experiencing long-term drought. In the West, conditions continued to deteriorate across the Pacific Northwest (Oregon, Washington, Idaho) and areas of the Intermountain West (Wyoming, Utah, and Colorado), while areas of eastern Montana saw improvement in drought in response to precipitation events during the past few weeks. In terms of reservoir storage in the West, Californiaโ€™s major reservoirs continue to be at or above historical averages for the date (July 29), with the stateโ€™s two largest reservoirs, Lake Shasta and Lake Oroville, at 105% and 116% of average, respectively. In the Southwest, the U.S. Bureau of Reclamation is reporting (July 27) Lake Powell at 32% full (46% of average), Lake Mead at 31% full (51%), and the total Colorado system at 39% of capacity (compared to 44% of capacity the same time last year)…

High Plains

On this weekโ€™s map, improvements continued from Kansas to North Dakota after another week of scattered shower activity with light-to-moderate accumulations. During the past 30 days, drought-related conditions have improved significantly in northern Kansas, eastern Nebraska, southeastern and southwestern South Dakota, and southwestern North Dakota as evidenced in a variety of drought monitoring products including streamflows, soil moisture, and vegetation health indicators. However, conditions have degraded in other parts of the region, including central South Dakota and northern North Dakota. For the week, average temperatures were generally above-normal average (1 to 6 degrees F) across the region, with eastern portions experiencing the largest departure, while far western portions of the Dakotas observed temperatures 1 to 4 degrees F below normal…

Colorado Drought Monitor one week change map ending July 29, 2025.

West

Out West, generally dry conditions prevailed over much of the region except for some isolated shower activity in northeastern California, northwestern Nevada, eastern New Mexico, eastern Colorado, and Montana. On the map, degradations were made across areas of the Pacific Northwest (Oregon, Washington, Idaho) and Intermountain West (Utah, Wyoming, Colorado). In the Pacific Northwest, streamflow activity continues to be well below normal levels across the Cascade Range of Oregon and Washington as well as in the mountain ranges of northern Idaho and western Montana. Similarly, poor surface water conditions were present in many streams and rivers of western Wyoming, Utah, western Colorado, central Arizona, and northern New Mexico. For the week, average temperatures were below normal across most of the region, with anomalies ranging from 2 to 10+ degrees F and the greatest departures observed across California and Nevada…

South

On this weekโ€™s map, improvements were made in areas of South Texas and the Trans Pecos region of Texas in response to above-normal precipitation during the past 30-120 days. In these regions, improvements were made in numerous drought categories (D1-D3). In other areas of the region, degradations occurred in southwestern Oklahoma, northern Mississippi, and central Tennessee, where rainfall has been below normal during the past 30 to 60 day period. For the week, average temperatures were above normal in the eastern and northern areas of the region, with anomalies ranging from 2 to 8 degrees F. Conversely, the western extent of the region, including areas in the southern half of Texas, experienced temperatures ranging from 1 to 4 degrees F below normal…

Looking Ahead

The NWS Weather Prediction Center (WPC) 7-Day Quantitative Precipitation Forecast (QPF) calls for generally dry conditions across much of the western U.S. except for some light shower activity (accumulations generally <1 inch) across areas of the Rockies (Idaho, Montana, Wyoming, Colorado) and mountain ranges of New Mexico. East of the Rockies, light-to-moderate accumulations (ranging from 1 to 4 inches) are expected across areas of the Plains states with the heaviest accumulations expected in western Oklahoma. In the lower Midwest, Mid-Atlantic, South (Gulf Coast areas), and portions of the Southeast, 1 to 5+ inch accumulations are forecast, with the heaviest accumulation expected along the coastal plains of Carolina and Georgia. The Climate Prediction Center (CPC) 6-10-day outlooks call for a moderate-to-high probability of above-normal temperatures across the Desert Southwest, southeastern portions of the Intermountain West, Plains, Midwest, New England, South, and southern portions of the Southeast region. In contrast, below-normal temperatures are forecast for areas of the West, including southern California, the Great Basin, and Pacific Northwest. In terms of precipitation, there is a low-to-moderate probability of above-normal precipitation across the Pacific Northwest, northern portions of the Intermountain West, northern Plains Midwest, Mid-Atlantic, and Southeast. Elsewhere, below-normal precipitation is expected across the southern half of the western U.S., southern Plains, and Texas.

#Coloradoโ€™s peak flash flood season — Russ Schumacher (Colorado Climate Center) #monsoon

Click the link to read the blog post on the Colorado Climate Center website (Russ Schumacher):

July 27, 2025

NOTE: Russ wrote this earlier in the week.

Itโ€™s been called the โ€œsummer of flash floodingโ€ in the US. The worst was the tragic flooding in Texas Hill Country on July 4, which took over 135 lives. But there have also been significant flash floods in other places across the country, from Ruidoso, New Mexico, to West Virginia, to Chicago, to the Washington, DC area, and many other places in between.

Here in Colorado, thankfully we havenโ€™t experienced a lot of flash flooding so far this summer. There have been a handful of flash flood warnings and reports, but no major incidents. However, we are now in the midst of the peak season for flash floods. The last 10 days or so of July and the first week of August are when weโ€™ve historically seen by far the most flash flood activity across the state.

Average number of reports of flood, flash flood, or debris flow in Colorado from 1996-2024. The brown line shows the average number of reports on each calendar day; the thick black line is a 15-day rolling average. Data source: NOAA/NCEI Storm Events Database.

One of the worst disasters in state history, the 1976 Big Thompson flood, happened on July 31. The Fort Collins flood of 1997: July 28. The Saguache Creek flood in the San Luis Valley in 1999: July 25. The heavy rain on the Grizzly Creek burn scar that closed I-70 for weeks in 2021: several rounds of storms in late July, especially on the 30th and 31st. And thatโ€™s just a sampling; the list could go on and on! 

Itโ€™s not the only time of year at which flash flooding happens in Colorado. The graph above shows another peak in early to mid June, which is when some other historic floods have occurred like the 1921 Arkansas River flood and the 1965 flood on the South Platte in Denver. Thereโ€™s also a big spike in September associated with the Great Colorado Flood of September 2013. Still, itโ€™s remarkable how sharp of a peak there is in late July into early August.

Whatโ€™s so special about late July and early August?

Meteorologically, the end of July through the beginning of August is when atmospheric moisture is at its highest on average. The North American Monsoon regularly transports moisture into Colorado in late summer, and at both Grand Junction and Denver, the precipitable waterโ€”the total amount of water vapor measured throughout the atmosphereโ€”peaks right around August 1.

At this time of year, the winds through the atmosphere tend to be pretty weak, as the jet stream is positioned far to our north. That means that when storms do form, they donโ€™t tend to move very quickly, and in some situations can stay over the same location for hours. And they have plenty of moisture to tap into (at least by Colorado standards), leading to large rainfall accumulations. 

Flash flooding isnโ€™t just about the rainfall, however. It also matters *where* that rain falls. When slow-moving, heavily raining storms develop over complex terrain, or over wildfire burn scars, that water can quickly turn into runoff or a debris flow. The combination of extreme rain rates in a steep canyon led to the Big Thompson flood. There were many unfortunate parallels between this monthโ€™s tragic flooding in Texas and the Big Thompson flood, including a rapid โ€œwall of waterโ€, people visiting the area on a holiday weekend, and challenges with communicating warnings, among others. Eve Gruntfestโ€™s analysis of what people did during the Big Thompson flood remains relevant and will provide a point of comparison for studies of the 2025 Texas hill country disaster.

What can we expect during flash flood season this year?

Last week, on July 22-24, there were some storms that produced heavy rainfall, and several flash flood warnings were issued across the state, but no significant flash flooding was reported. Then, the moisture moved out, resulting in very hot and dry conditions for late July. But the outlook for the coming week has some reason for concern, in part because itโ€™s our climatological peak in flash flooding, and also because a significant surge of moisture will move into Colorado. 

Following the near-record highs and dry conditions on Sunday and Monday, a cold front is expected to move through Colorado sometime on Tuesday, with winds from the east (i.e., upslope flow) and plentiful moisture behind it. This figure from NOAAโ€™s Global Ensemble Forecast System shows the precipitable water at Denver going from extremely low on Sunday (below the climatological 10th percentile) to extremely high (above the 90th percentile) on Wednesday. Anytime the PW gets above 25 mm (~1 inch) it warrants paying attention to for the potential of heavy rainfall.

Each colored line represents a different member of the ensemble, and the thick black line is the ensemble mean. The dashed gray lines show the 10th and 90th percentiles and the solid gray line shows the median, based on historical radiosonde observations.

For the last several years, my research group has developedย tools that use machine learning to identify the probability of excessive rainfall and severe weather. These models have been consistently showing a strong signal for heavy rainfall along the Front Range on Wednesday, July 30th. In fact, for the current version of these models that have been running since 2020, this is the first time that both models (which were trained using slightly different definitions of โ€˜excessive rainfallโ€™) have had probabilities greater than 20% four days in advance along the northern Front Range. Probabilities are relatively high for Thursday the 31st as well.

Flash flooding remains extremely difficult to forecast, because it requires predicting both the rainfall itself, and what will happen to that water once it hits the ground. So itโ€™s too early to say exactly what will play out this week. But when forecast models are pointing to the potential for heavy rainfall that lines up with the climatological peak in flash flooding (the last week of July), itโ€™s worth keeping a close eye on. If you live in a flood-prone area, or will be traveling through a beautiful Front Range canyon this week, take a moment to think about how youโ€™ll get warnings if they are issued (do you have a NOAA weather radio?), and what you might do in case of a flash flood.

Re-upping this post for July 31, 2025. The flood remains Colorado’s deadliest. Here’s a link to Coyote Gulch coverage mentioning the Big Thompson Flood.

July 31, 1976, Steamboat Springs: I had been wandering around the Flat Tops Wilderness for a week or so with Mrs. Gulch. Drizzle in between downpours during the monsoon. We were holed-up in a hotel to dry out and I phoned my mother to check in.

She asked, “Johnny are you anywhere near the Big Thompson Canyon? There’s been a terrible flood.”

And it was a terrible flood. After the September 2013 floods Allen Best wrote about being part of the disaster response in The Denver Post. It’s a good read on this 40th anniversary. Here’s one passage:

I was at the Big Thompson disaster. I was living in Fort Collins then and was among scores of young men (sorry, women, those were different times) with strong backs who could be summoned in case of forest fires. My only fire was at an old sawmill site in the foothills. The joke was that one of us had set the fire because we were so desperate for minimum-wage work.

Then came July 31. It was hot that night in Fort Collins. It hadnโ€™t rained a drop.

I was living above Geneโ€™s Tavern, just two blocks from the Larimer County Courthouse. When the call came, I was at the sheriffโ€™s office almost immediately. It was 9 p.m.

Being among the first at the command center at the Dam Store west of Loveland, near the mouth of Big Thompson Canyon, I was assigned to a pickup dispatched to look for people in the water near the turnoff to Masonville. Already, the river was out of its banks. From the darkness emerged a figure, dripping and confused. โ€œI went fishing at Horsetooth (Reservoir) and was driving home and then there was all this water,โ€ he sputtered. He was befuddled. So were we.

Our leader decided weโ€™d best get out of there. From what I saw the next morning, that was an excellent decision. Water later covered the road there, too. I spent the night at the Dam Store as the water rose. Helicopters were dispatched, but there was little that could be done. Our lights revealed picnic baskets, beach balls and propane bottles bobbing in the dark, roiling water that raced past us, but never any hands summoning help.

In the morning, we found those hands. The bodies were stripped of clothing and covered with mud. The first I saw was of a woman who we guessed was 18, not much younger than I was then. This thin margin between life and death was startling in my young eyes.

Eventually, 144 people were declared victims of the flooding that night (although one turned up alive in 2008 in Oklahoma).

Estes Park got some rain, but not all that much. The larger story was partway down the canyon, in the Glen Haven and Glen Comfort areas, where the thunderstorm hovered. In just a few hours, it dropped 10 to 14 inches of water.

Downstream in the canyon, just above the Narrows, some people were unaware that anything was amiss until they went outside their houses and saw the water rising in their yards. It hadnโ€™t even rained there. One cabin I saw a few days later was stripped of doors and windows but stood on its foundations, a mound of mud 5 or 6 feet high in the interior. I seem to recall a dog barking as we approached, protecting that small part of the familiar in a world gone mad.

At the old hydroelectric plant where my family had once enjoyed Sunday picnics, the brick building had vanished. Only the turbines and concrete foundation remained. In a nearby tree, amid the branches maybe 10 or 15 feet off the ground, hung a lifeless body.

The river that night carried 32,000 cubic feet per second of water at the mouth of the canyon, near where I was stationed. It happened almost instantaneously โ€” and then it was gone. It was a flash flood.

Here’s an excerpt from a look back forty years from Michelle Vendegna writing for the Longmont Times-Call.

Night on the ledge

“We, Terry Belair-Hassig and Connie Granath-Hays, graduated from Berthoud Jr. Sr. High School the month before, and were anxious to begin the summer. We spent the beautiful, sunny day of July 31, 1976, at a Hewlett-Packard company picnic at Hermit Park not far from Estes Park. After the picnic, we drove up to Estes Park and had dinner at Bob and Tony’s Pizza.

The clouds started moving in about 6 p.m., so we began the drive down to Loveland via U.S. 34. Within minutes, Connie had to pull her car over because the driving rain was causing zero visibility. We needed to get home, so she started out again, but we didn’t get too much farther before we were blocked by trees, boulders and debris washing down the canyon sides. We had just passed the Loveland Heights area โ€” barely three miles since entering the canyon. The closest town, Drake, was miles away.

Connie pulled over to the side of the mountain as far as she could. There were a few other cars in this section doing the same, but we all sat in our cars โ€” planning to wait out the storm. However, once the river began to rise and the water was hitting the tires, we decided to leave the car and start climbing. Connie’s dad had taught her to always ‘be prepared,’ so she had a tarp and a few extra jackets stored in her trunk. We grabbed them before climbing. It was a dark, treacherous climb.

A small group of people scrambled up the mountain near us. Connie gave one of the men her extra jacket. She also had a flashlight which came in handy later in the evening when the lightning wasn’t lighting up the canyon. The other people were lucky enough to find an overhang of rocks to sit under. We tentatively settled on a ledge out in the open, and wrapped ourselves in the tarp. Of course, the tarp was just an old tarp, not waterproof like the ones are today. It protected us for a while, but with the downpour of rain and runoff from the hillside, it too became drenched.

After only a little while, we watched her car, during the lightning flashes, being lifted up and carried down the river. We decided at this point we should climb higher, so we found a ledge where we spent the long, cold night. We had spent many winters skiing and had never been as cold as we were that night.

We sat on that little ledge (3 foot by 1 foot) with our knees drawn up to keep us from sliding off. We sang, shivered, cussed and did anything we could to keep our minds off of how cold and achy we were. We heard and saw cars, houses and propane tanks floating down the river during flashes of lightning. We thought by now it must be about morning time, but looking at our watch, it was about 10 p.m. We had a long night ahead of us.

The next morning was another blue bird day and we were freezing and soaked to the bone. We decided it would be warmer to take our jackets off and left them on the ledge. The road below us had been washed away, but the river had receded enough that we could get off the ledge and move around a little on the steep mountainside. We heard the helicopters for a long time before we saw one. Finally, we were rescued off the side of the mountain by a four-seat helicopter,and dropped off up river on a section of the highway that had survived. There were several other people there. I remember we were all surveying the canyon in a daze. There wasn’t much conversation. I leaned over and picked up a small piece of asphalt and put it in my pocket.

From Wikipedia:

On July 31, 1976, during the celebration of Colorado’s centennial, the Big Thompson Canyon was the site of a devastating flash flood that swept down the steep and narrow canyon, claiming the lives of 143 people, 5 of whom were never found. This flood was triggered by a nearly stationary thunderstorm near the upper section of the canyon that dumped 300 millimeters (12 inches) of rain in less than 4 hours (more than 3/4 of the average annual rainfall for the area). Little rain fell over the lower section of the canyon, where many of the victims were.

Around 9 p.m., a wall of water more than 6 meters (20 ft) high raced down the canyon at about 6 m/s (14 mph), destroying 400 cars, 418 houses and 52 businesses and washing out most of U.S. Route 34. This flood was more than 4 times as strong as any in the 112-year record available in 1976, with a discharge of 1,000 cubic meters per second (35,000 ftยณ/s).

From The Greeley Tribune (Tyler Silvy):

Officials on Friday detailed how a Big Thompson River that was flowing at 30 cubic feet per second increased to 30,000 by the time it got to the narrows near Sylvan Ranch and the Dam Store.

The 2013 flood, by contrast was flowing at 16,000 cubic feet per second at the same point. But Bob Kimbrough, from the U.S. Geological Survey, said that number can be misleading. Just because it was flowing at less than half the rate, doesnโ€™t mean the water was half as high as it was in 1976. It could have been a foot or two lower, Kimbrough said.

Further, the 2013 flood lasted longer. Where the 1976 flood dissipated nearly as quickly as it rose, the 2013 flood flowed over saturated ground for days, causing foundation failures and greater erosion than the 1976 flood.

๐Ÿ“ˆ Data CENTER Dump ๐Ÿ“Š

When I first read a recent headline in Matthew Yglesiasโ€™s Slow Boring newsletter, I assumed it was a sort of joke to rope me into reading. โ€œThereโ€™s plenty of water for data centers,โ€ it said, reassuringly. โ€œProbably the last worry you should have about either water or AI.โ€

Unfortunately, he wasnโ€™t joking. But he opened his piece with a line that should have warned his readers to take everything else he said with a grain of salt:

Before I continue with my rant, Iโ€™d just like to encourage Yglesias to do a little more thinking about water scarcity before writing about it. Oh, and also, maybe consider spending a little bit of time in the water-starved West before committing punditry about it. (This is the same guy who tweeted that Sen. Mike Leeโ€™s proposal to sell off public land was โ€œpretty reasonableโ€ and an โ€œokay idea on the meritsโ€).

Yglesias acknowledges that data centers use water, and that more data centers will lead to more water consumption. But itโ€™s okay, he says, because โ€œWeโ€™re not living on Arrakis, and rich countries are not, in general, abstemious in their water usage.โ€

No, we are not on Arrakis, but have you seen the lower reaches of the Colorado River or even the mid-reaches of the Rio Grande lately? Itโ€™s looking pretty Dune-like if you ask me.

Well, sure, Yglesias argues, but even in those places, people are doing frivolous things with water, like filling up their Super Soakers or using it to make ice cubes for their cocktails. Yes, he used those actual examples. Never mind that the potable water used each day by a single Microsoft data center in Goodyear, Arizona, could yield more than 35 million ice cubes or fill about 223,000 Super Soakers. That would be one big, drunken water fight.

Yglesias also notes that agriculture, especially growing alfalfa and other feed crops for cattle, is an even larger water consumer than Big Tech. True, for now. And he writes:

His logic appears to be: People are currently using a lot of water for all sorts of things โ€” frivolous or otherwise. So, it should be fine to use a lot more water for data centers in perpetuity, since water is โ€œsufficiently plentiful.โ€ This is the sort of thinking that got the Colorado River Basin into its current mess, in which there actually may not be enough water to drink very soon if its collective users donโ€™t change their ways. Adding a fleet of water-guzzling hyperscale data centers to places like Phoenix, Las Vegas, andย Tucson, where water is anything but โ€œsufficiently plentiful,โ€ will only exacerbate the crisis.


A Dog Day Diatribe on AI, cryptocurrency, energy consumption, and capitalism — Jonathan P. Thompson


Researchers have tried various methods to determineย how much water a single ChatGPT query or AI-assisted Google search usesย as compared to, say, streaming a Netflix video or writing a standard e-mail.ย So far the estimates diverge wildly. An early calculation came up with a whopping 500 ml for each AI query, but the estimates have since gone down. The difficulty is due in part to the fact that water use data isnโ€™t always publicly available, and also because data centersโ€™ water use can vary depending on location, as do theirย carbon footprints.

What is clear is this: Data centers use large quantities of both energy and water, no matter where they are. The massive server banks churning away in warehouse-like buildings on the fringes of Phoenix and Las Vegas, and even in rural Washington and Wyoming, each gobble as much electricity as a small city to process AI queries, cryptocurrency extraction, and other aspects of our increasingly cloud-based society. The harder they work, the hotter they get, and the more power and water they need to cool off to the optimum operating temperature of between 70ยฐ to 80ยฐ F.

Evaporative or adiabatic cooling, where air is cooled by blowing it through moistened pads (i.e. high-tech swamp coolers), works well in arid areas like Phoenix, Tucson, or Las Vegas. They use less energy than refrigerated cooling, but also use far more water.

Data centers can also indirectly consume water through their energy use, depending on the power source. Thermal coal, nuclear, or natural gas plants need water for cooling and steam-production (some of this water may be returned to the source after use, except with zero-discharge facilities); natural gas extraction uses water for hydraulic fracturing; and solar installations can require large amounts of water for dust-suppression and cleaning. This explains how Googleโ€™s data centers withdrew 8.65 billion gallons of water globally in 2023 1.


Energy-Water Nexus Data Dump 1: Fracking — Jonathan P. Thompson


A 2023 study found that a single Chat GPT-3 request processed at an Arizona data center uses about 30 milliliters of water, compared to 12 ml per request in Wyoming. That doesnโ€™t seem like much (itโ€™s less than a shot-glass) until you consider that there are at least 1 billion ChatGPT queries worldwide per day and growing, using a total of some 8 million gallons of water daily, worldwide. And, training the AI at an Arizona data center would use about 9.6 million liters โ€” or 2.5 million gallons โ€” of additional water.

Another estimate finds the average data center uses between 1 million and 5 million gallons of water per day, onsite, which would be far more than the aforementioned Goodyear center (56 million gallons/year), but in line with a planned Google data center in Mesa, Arizona. When Google was first planning the facility back in 2019, the city of Mesa guaranteed delivery of nearly 1 million gallons of water per day. If they reach certain milestones they can use up to 4 million gallons daily, or about 4,480 acre-feet per year.

Now multiply those numbers by the more than 90 data centers of various sizes and water and energy intensity in the Phoenix area, alone, which would amount to somewhere between 14 million to 450 million gallons per day. No matter how you add it up, they collectively are sucking up a huge amount of water and power, and enough to strain even Yglesiasโ€™s purported โ€œsufficiently plentifulโ€ supplies (which do not exist in Arizona, by the way).

The average Phoenix-area household uses about 338 gallons of water per day, or almost 123,000 gallons per year. One of these big data centers, then, could guzzle as much water as some 10,000 homes. And yet housing developments in groundwater-dependent areas on Phoenixโ€™s fringe must obtain 100-year assured water supply certification before they can begin building. The same is not the case for data centers.

According to Open ET maps, a 75-acre alfalfa field in Buckeye (western Phoenix metro area), uses about 156 acre-feet โ€” or 50.8 million gallons โ€” per year. Thatโ€™s far less than the 28-acre Apple Data Center in Mesa consumes. Of course, there are the equivalent of about 3,470 alfalfa fields of that same size in Arizona (260,000 acres), meaning the total water consumption of hay and alfalfa is still greater than that of data centers. But it shows that while replacing an alfalfa field with houses would result in a net decrease in water consumption, replacing those same fields with data centers would substantially increase consumption.

And donโ€™t forget that the 75-acre alfalfa field produces about 690 tons of alfalfa per year, which could feed quite a few dairy cows, which in turn would produce a bunch of milk for making cheese and ice cream. Just saying. Maybe itโ€™s time to update the old saying: โ€œIโ€™d rather see a cow than a data center.โ€


Western water: Where values, math, and the “Law of the River” collide, Part I — Jonathan P. Thompson


Data centers arenโ€™t going away. After all, they are the hearts and brains of the Internet Age. Many of us may wish that AI (not to mention cryptocurrency), which are more water- and energy-intensive than other applications, would just up and vanish. But thatโ€™s probably too much to ask for. Besides, AI, at least, does have real value. 

So what can be done to keep the data center boom from devouring the Westโ€™s water and driving its power grid to the snapping point? Hereโ€™s where Yglesias had a good point: Policymakers and utilities should adjust water and power pricing for large industrial users, i.e. data centers, to discourage waste, incentivize efficiency and recycling, and push tech firms to develop their own clean energy sources to power their facilities.

Itโ€™s imperative that utilities force data centers to pay their fair share for infrastructure upgrades made necessary by added water or power demand, rather than shifting those costs to other ratepayers, as is usually the case. Arizona should make data centers prove out their water supply, just like they do with housing developments. Plus, states should stop trying to lure data centers with big tax breaks, which ultimately are paid for by the other taxpayers. And local governments and planners should subject proposed data centers to the highest level of scrutiny, and not give in to promises of jobs and economic development if it means sacrificing the communityโ€™s water supply or the reliability of the power grid.

Proper policy isnโ€™t a cure all, by any means. But it could mitigate the impacts of the imminent data center boom. Meanwhile, Mr. Yglesias, I will reiterate that the West, at least, does not have plenty of water for data centers, and I will continue to worry about them guzzling up what little water remains.

JULY 29, 2025

DENVER – Today, by repealing the 16-year-old “Endangerment Finding,โ€ which determined that greenhouse gas (GHG) pollution poses a threat to public health and welfare, the Trump administrationโ€™s U.S. Environmental Protection Agency (EPA) paved the way for more extreme weather and natural disasters, hurting Colorado communities. 

โ€œThis decision flies in the face of decades of data about the negative public health impact of greenhouse gasses including heat exposure and fire risk. Colorado is all too familiar with the impacts of climate change, seeing the three largest fires in our state’s history and the most destructive in the last five years. Despite the EPAโ€™s denial of our reality, Colorado will continue to achieve our ambitious clean energy goals to save people more on energy bills, reduce emissions and improve our air-quality and health,โ€ said Governor Jared Polis. 

Climate change is already negatively impacting Coloradans in all aspects of life. Homeownerโ€™s insurance costs are skyrocketing due to increased hail and fire claims. Extreme weather is destroying homes, jobs, and crops. In 2024, the United States experienced $27 billion in weather- and climate-related disasters. And higher temperatures are increasing the risk of illness and medical emergencies.

Fort Collins, Spring Creek flood July 28, 1997
  • Heavy rainfall in late July in Colorado’s past caused two of the state’s worst floods, the Spring Creek Flood and the Big Thompson Flood.
  • The 1997 Spring Creek Flood resulted in five deaths and over $200 million in damages in Fort Collins.
  • The 1976 Big Thompson Flood led to 144 fatalities and $35 million in damages.

Twenty-eight years ago this week, 14 inches of rain fell on Fort Collins in just over a day, overwhelming the Spring Creek and leading to the deaths of five people.

And 49 years ago this week, more than a foot of rain fell on the Big Thompson River west of Loveland in about four hours, creating a wall of water that swept away and killed 144 people. It’s not a coincidence that both events happened in the same week of July, though they were years apart. It’s flash-flood season in Colorado, and three of the state’s worst floods occurred from mid-July through mid-September, which is also the state’sย monsoon season.

‘So much has been taken’: Apache women sue to halt land swap for Oak Flat copper mine — AZCentral.com

Oak Flat, Arizona features groves of Emory oak trees, canyons, and springs. This is sacred land for the San Carlos Apache tribe. Resolution Copper (Rio Tinto subsidiary) lobbied politicians to deliver this National Forest land to the company with the intent to build a destructive copper mine.

Key Points

  • A group of Apache women has asked a court to stop a land exchange that would lead to a huge copper mine at Oak Flat.
  • The suit is the latest attempt to block Resolution Copper from building the mine on land east of Phoenix considered sacred to the Apache and other tribes.
  • A judge will hear arguments in a separate lawsuit next week as the date nears for the land swap to take place.

A group of Apache women asked a federal judge in Washington, D.C., to halt a disputed land exchange at the center of a long battle over plans to build a huge copper mine at Oak Flat. It’s the fourth lawsuit that seeks to stop the U.S. Forest Service from signing over title to the site, held sacred by Apache peoples and culturally significant by other tribes, to Resolution Copper in exchange for other plots of environmentally sensitive land in Arizona. The four women, who all have spiritual and cultural connections to the 2,200-acre campground inย Tonto National Forestย about 60 miles east of Phoenix, filed their suit in theย U.S. District Court for the District of Columbiaย July 24. Nelson Mullins, a law firm based in Washington, D.C., and South Carolina, outlined the case, which asks Judge Timothy J. Kelly, an appointee of President Donald Trump, to stop the exchange until the plaintiffs can have their day in court. The suit claims the exchange violates the Religious Freedom Restoration Act, the plaintiffs’ First Amendment-guaranteed religious rights protections and two environmental laws.

Redefining #drought — Western Governor’s Association

July 24, 2025

Redefining Drought:ย Drought is often defined as โ€œdrier-than-normal,โ€ but if the climate is shifting, whatโ€™s considered the new normal? While a larger sample size reduces uncertainty, it could also create a baseline that isnโ€™t representative of todayโ€™s climate.

With ample data collected via the National Integrated Drought Information System, which Western Governors helped create in 2003, The National Academies of Sciences, Engineering, and Medicineโ€ฏis working on a study to determine the best way to manipulate that data in ways that are the most useful for different water users.

For instance, “if you’re in a place where the precipitation is declining, such as far Western Texas or New Mexico, or possibly you’re relying on stream or river flow to irrigate your crop, and that water resource is declining, you want to be able to think ahead and be aware of the average amount of water you have access to,โ€ said Joel Lisonbee, a senior associate scientist at the Cooperative Institute for Research in the Environmental Sciences, or CIRES, at the University of Colorado in Boulder. In those cases, it may make sense to use a shorter baseline to reflect recent trends, rather than include data from a century ago, when the climate was different.

“What we should be asking is, when should drought be defined using all available data? When should we use the whole climate record?” Lisonbee said. “There’s not one answer, and the correct answer will really depend on why you’re assessing drought in the first place.โ€  

How #wind and #solar power helps keep Americaโ€™s farmsย alive — Paul Mwebaze (TheConvesation.com)

Drive through the plains of Iowa or Kansas and youโ€™ll see more than rows of corn, wheat and soybeans. Youโ€™ll also see towering wind turbines spinning above fields and solar panels shining in the sun on barns and machine sheds.

For many farmers, these are lifelines. Renewable energy provides steady income and affordable power, helping farms stay viable when crop prices fall or drought strikes.

But some of that opportunity is now at risk as the Trump administration cuts federal support for renewable energy.

Wind power brings steady income for farms

Wind energy is a significant economic driver in rural America. In Iowa, for example, over 60% of the stateโ€™s electricity came from wind energy in 2024, and the state is a hub for wind turbine manufacturing and maintenance jobs.

For landowners, wind turbines often mean stable lease payments. Those historically were around US$3,000 to $5,000 per turbine per year, with some modern agreements $5,000 to $10,000 annually, secured through 20- to 30-year contracts.

Nationwide, wind and solar projects contribute about $3.5 billion annually in combined lease payments and state and local taxes, more than a third of it going directly to rural landowners.

A U.S. map shows the strongest wind power potential in the central U.S., particularly the Great Plains and Midwestern states.
States throughout the Great Plains and Midwest, from Texas to Montana to Ohio, have the strongest onshore winds and onshore wind power potential. These are also in the heart of U.S. farm country. The map shows wind speeds at 100 meters (nearly 330 feet), about the height of a typical land-based wind turbine. NREL

These figures are backed by long-term contracts and multibillionโ€‘dollar annual contributions, reinforcing the economic value that turbines bring to rural landowners and communities.

Wind farms also contribute to local tax revenues that help fund rural schools, roads and emergency services. In counties across Texas, wind energy has become one of the most significant contributors to local property tax bases, stabilizing community budgets and helping pay for public services as agricultural commodity revenues fluctuate.

In Oldham County in northwest Texas, for example, clean energy projects provided 22% of total county revenues in 2021. In several other rural counties, wind farms rank among the top 10 property taxpayers, contributing between 38% and 69% of tax revenue.

The construction and operation of these projects also bring local jobs in trucking, concrete work and electrical services, boosting small-town businesses.

The U.S. wind industry supports over 300,000 U.S. jobs across construction, manufacturing, operations and other roles connected to the industry, according to the American Clean Power Association.

Renewable energy has been widely expected to continue to grow along with rising energy demand. In 2024, 93% of all new electricity generating capacity was wind, solar or energy storage, and the U.S. Energy Information Administration expected a similar percentage in 2025 as of June.

Solar can cut power costs on the farm

Solar energy is also boosting farm finances. Farmers use rooftop panels on barns and ground-mounted systems to power irrigation pumps, grain dryers and cold storage facilities, cutting their power costs.

Some farmers have adopted agrivoltaics โ€“ dual-use systems that grow crops beneath solar panels. The panels provide shade, helping conserve water, while creating a second income path. These projects often cultivate pollinator-friendly plants, vegetables such as lettuce and spinach, or even grasses for grazing sheep, making the land productive for both food and energy.

Federal grants and tax credits that were significantly expanded under the 2022 Inflation Reduction Act helped make the upfront costs of solar installations affordable.

However, the federal spending bill signed by President Donald Trump on July 4, 2025, rolled back many clean energy incentives. It phases down tax credits for distributed solar projects, particularly those under 1 megawatt, which include many farmโ€‘scale installations, and sunsets them entirely by 2028. It also eliminates bonus credits that previously supported rural and lowโ€‘income areas.

Without these credits, the upfront cost of solar power could be out of reach for some farmers, leaving them paying higher energy costs. At a 2024 conference organized by the Institute of Sustainability, Energy and Environment at the University of Illinois Urbana-Champaign, where I work as a research economist, farmers emphasized the importance of tax credits and other economic incentives to offset the upfront cost of solar power systems.

Whatโ€™s being lost

The cuts to federal incentives include terminating the Production Tax Credit for new projects placed in service after Dec. 31, 2027, unless construction begins by July 4, 2026, and is completed within a tight time frame. The tax credit pays eligible wind and solar facilities approximately 2.75 cents per kilowatt-hour over 10 years, effectively lowering the cost of renewable energy generation. Ending that tax credit will likely increase the cost of production, potentially leading to higher electricity prices for consumers and fewer new projects coming online.

The changes also accelerate the phaseโ€‘out of wind power tax credits. Projects must now begin construction by July 4, 2026, or be in service before the end of 2027 to qualify for any credit.

Meanwhile, the Investment Tax Credit, which covers 30% of installed cost for solar and other renewables, faces similar limits: Projects must begin by July 4, 2026, and be completed by the end of 2027 to claim the credits. The bill also cuts bonuses for domestic components and installations in rural or lowโ€‘income locations. These adjustments could slow new renewable energy development, particularly smaller projects that directly benefit rural communities.

While many existing clean energy agreements will remain in place for now, the rollback of federal incentives threatens future projects and could limit new income streams. It also affects manufacturing and jobs in those industries, which some rural communities rely on.

Renewable energy also powers rural economies

Renewable energy benefits entire communities, not just individual farmers.

Wind and solar projects contribute millions of dollars in tax revenue. For example, in Howard County, Iowa, wind turbines generated $2.7 million in property tax revenue in 2024, accounting for 14.5% of the countyโ€™s total budget and helping fund rural schools, public safety and road improvements.

In some rural counties, clean energy is the largest new source of economic activity, helping stabilize local economies otherwise reliant on agricultureโ€™s unpredictable income streams. These projects also support rural manufacturing โ€“ such as Iowa turbine blade factories like TPI Composites, which just reopened its plant in Newton, and Siemens Gamesa in Fort Madison, which supply blades for GE and Siemens turbines. The tax benefits in the 2022 Inflation Reduction Act helped boost those industries โ€“ and the jobs and local tax revenue they bring in.

On the solar side, rural companies like APA Solar Racking, based in Ohio, manufacture steel racking systems for utility-scale solar farms across the Midwest. https://www.youtube.com/embed/Bcet_aaaMq8?wmode=transparent&start=0 An example of how renewable energy has helped boost farm incomes and keep farmers on their land.

As rural America faces economic uncertainty and climate pressures, I believe homegrown renewable energy offers a practical path forward. Wind and solar arenโ€™t just fueling the grid; theyโ€™re helping keep farms and rural towns alive.

Water treatment plant set for 2025 groundbreaking — Gunnison Country Times #GunnisonRiver

The water treatment process

Click the link to read the article on the Gunnison Country Times website (Alex McCrindle). Here’s an excerpt:

July 23, 2025

On July 22, after months of uncertainty about the impact of federal funding cuts and tariffs, Gunnison City Council received an update on the future of the water treatment plan project. Gunnison Public Works Director Pete Rice addressed the council with a report on funding, design and construction of the proposed plant on the Van Tuyl Ranch. The water treatment plant, estimated to cost $50 million and be one of the largest infrastructure developments in city history, is divided into three projects. The first project covers the construction of a raw water intake and three separate wells at the VanTuyl Ranch. The second and third projects focus on the water delivery system and water treatment facility. With the first project nearing approval from the Environmental Protection Agency (EPA), the city is expected to finalize its design this fall and begin construction before the end of 2025. The treatment plant initiative stems from the 2021 water master plan and a potable water evaluation. Gunnison currently relies on nine wells to source its drinking water. The system is outdated and no longer permitted by the state. Because all of the wells pull water from the same aquifer, drinking water is vulnerable to contamination and extended drought conditions. The proposed plant will allow Gunnison to pull water from the Gunnison River, in addition to the aquifer…

The first project includes the construction of a raw water intake and three separate wells. The proposed intake will be 18-feet deep alongside the Gunnison River, and cylindrical intakes will extend halfway into the river. The first project is expected to be approved by the EPA in the next four weeks, and begin construction this year with well drilling extending into 2026. The project is projected to cost $4 million, with $900,000 covering design, and $3 million going toward construction. The entire construction cost is funded by $1.75 million in congressionally directed spending, and $1.5 million from a Colorado Water Conservation Board grant. Four additional grants covered roughly $850,000 in design costs. The City of Gunnison will pay the remaining $25,000. Once complete, the water intake will have little impact on outdoor recreation, including boating and fishing, Rice said. However, construction will likely disrupt those activities for an estimated two to three months. It is currently unknown if construction can take place in the winter to minimize impact on summer recreation. Project two focuses on a complex network of pipes that will connect the raw water intake and wells, and deliver water directly to the water treatment plan. The third project is the construction of the water treatment plant itself. Rice said the second and third project design is estimated to be completed between winter 2025 and spring 2026, with construction lasting into 2029. The two projects will cost $2.7 million for design, and $40 million for construction. The majority of design costs are already funded by six grants, while the construction costs are set to be discussed at upcoming council meetings.

8 Things to Know About New Research on Earthโ€™s Rapid Drying and the Loss of Its Groundwater — ProPublica.org

Click the link to read the article on the ProPublica website:

July 28, 2025

The continents are rapidly drying out and the earthโ€™s vast freshwater resources are under threat, according to a recently released study based on more than 20 years of NASA satellite data. Here are the reportโ€™s key findings and what they portend for humankind:

Much of the Earth is suffering a pandemic of โ€œcontinental drying,โ€ affecting the countries containing 75% of the worldโ€™s population, the new research shows.

The study, published in the journal Science Advances, examined changes to Earthโ€™s total supply of fresh water and found that nearly 6 billion people live in the 101 countries facing a net decline in water supply, posing a โ€œcritical, emerging threat to humanity.โ€

Mining of underground freshwater aquifers is driving much of the loss.

According to the study, the uninhibited pumping of groundwater by farmers, cities and corporations around the world now accounts for 68% of the total loss of fresh water at the latitudes where most people live.

Much of the water taken from aquifers ends up in the oceans, contributing to the rise of sea levels.

Mined groundwater rarely seeps back into the aquifers from which it was pumped. Rather, a large portion runs off into streams, then rivers and ultimately the oceans. According to the researchers, moisture lost to evaporation and drought, plus runoff from pumped groundwater, now outpaces the melting of glaciers and the ice sheets of either Antarctica or Greenland as the largest contributor of water to the oceans.

Water From Land Has Become a Leading Driver of Sea Level Rise

Most of the water lost from drying regions is from groundwater pumping, which ultimately shifts fresh water from aquifers into the oceans.

Note: Glaciers refer to the parts of the continents covered in glaciers but excludes the ice sheets of Greenland and Antarctica. Drying land and aquifers refer to the water lost by the continents in areas not covered by glaciers, including river flow and evaporation. Groundwater loss accounts for 68% of the drying in those places. Credit: Lucas Waldron/ProPublica

As droughts grow more extreme, farmers increasingly turn to groundwater.

Worldwide, 70% of fresh water is used for growing crops, with more of it coming from groundwater as droughts grow more extreme. Only a small amount of that water seeps back into aquifers. Research has long established that people take more water from underground when climate-driven heat and drought are at their worst.

Drying regions of the planet are merging.

The parts of the world drying most acutely are becoming interconnected, forming what the studyโ€™s authors describe as โ€œmegaโ€ regions. One such region covers almost the whole of Europe, the Middle East, North Africa and parts of Asia.

Drying of the Earth has accelerated in recent years.

The study examines 22 years of observational data from NASAโ€™s Gravity Recovery and Climate Experiment, or GRACE, satellites, which measure changes in the mass of the earth and have been applied to estimate its water content. Since 2002, the sensors have detected a rapid shift in water loss across the planet. Around 2014, the study found the pace of drying appears to have accelerated. It is now growing by an area twice the size of California each year.

The Drying of the Earth Accelerated in Recent Years

The dramatic depletion of groundwater and surface water plus the melting of glaciers between 2014-24 has connected once-separate arid places, forming โ€œmega-dryingโ€ regions that stretch across whole continents.

Note: Data is for February 2003 to December 2013 and January 2014 to April 2024. The first time period contains seven more months of data than the second.

Water pumped from aquifers is not easily replaced, if it can be at all.

Major groundwater basins underlie roughly one-third of the planet, including about half of Africa, Europe and South America. Many of those aquifers took millions of years to form and might take thousands of years to refill. The researchers warn that it is now nearly impossible to reverse the loss of water โ€œon human timescales.โ€

As continents dry and coastal areas flood, the risk for conflict and instability increases.

The accelerated drying, combined with the flooding of coastal cities and food-producing lowlands, heralds โ€œpotentially staggeringโ€ and cascading risks for global order, the researchers warn. Their findings all point to the likelihood of widespread famine, the migration of large numbers of people seeking a more stable environment and the carry-on impact of geopolitical disorder.
