Stratospheric aerosol injection, (SAI), is a theoretical solar geoengineering proposal that involves dispersing sulfate (or other reflective particles) into the stratosphere to reflect a portion of incoming sunlight back into space. Research into delivery methods focuses on platforms capable of reaching the stratosphere, which begins at varying altitudes depending on the latitude. Proposals range from spraying reflective particles, such as sulfur dioxides, finely powdered salt or calcium carbonate, from aircraft or high-flying balloons. None of these solar geo-engineering strategies address the underlying causes of climate change. Instead, they aim to control the amount of incoming solar radiation by emulating the sulfur-rich dust cloud that remains in the atmosphere after large volcanic eruptions.1
Proof of Concept provided by Mt. Pinatubo
The 1991 eruption of Mount Pinatubo injected approximately 17 million tons of sulfur dioxide into the stratosphere, creating a global layer of sulfuric acid haze that significantly increased the Earth’s albedo. This aerosol veil reflected incoming solar radiation back into space, resulting in a measurable drop in global mean temperatures of approximately 0.5ยฐC (0.9ยฐF) between 1992 and 1993. This transient cooling effect temporarily offset the trend of anthropogenic global warming and disrupted global precipitation patterns, demonstrating the profound impact that volcanic stratospheric aerosols can have on the Earth’s energy balance.2
According to one study, by sending specially designed high-altitude airplanes on roughly 4,000 total sulfate injection missions a year, humans could replicate this same level of cooling. This has the potential to offset half of the warming expected over the studyโs 15-year period and counteract billions of metric tons of CO2 emissions each year. At a cost of around $2 billion annually, even medium-sized economies could afford such a program. This price tag would also be far less expensive than the potential impacts of climate change. Take the United States: the 2018 US National Climate Assessment Report estimates the impacts of climate change damages will amount to โhundreds of billions of dollars annuallyโ by 2090, making atmospheric sulfate injection an appealing solution.3
Aerial platforms under consideration
Large commercial or military transport aircraft: These could potentially be retrofitted with specialized tanks and nozzle systems. However, most standard aircraft have flight ceilings that only reach the lower stratosphere, particularly near the poles.
Specialized Research Planes: Aircraft designed for high-altitude atmospheric research, such as those used by space agencies, can reach the higher altitudes (around 20 km) often cited as optimal for SAI. These generally have limited payload capacities.
Purpose-Built High-Altitude Jets: Many researchers suggest that a new class of specialized aircraft would be necessary for efficient, large-scale delivery. These designs would require high-lift wings and engines capable of sustained operation in thin air while carrying heavy payloads of aerosol precursors.
High-Altitude Balloons: Tethered or free-floating balloons have been proposed as a lower-cost method to loft materials into the stratosphere, though they face challenges related to stability and large-scale operational control.4
Potential benefits
Rapid Global Cooling: SAI can lower global average temperatures much faster than carbon removal methods. Historical volcanic eruptions, like Mount Pinatubo in 1991, have proven that atmospheric sulfur can cool the planet by roughly 0.5ยฐC within a year.
Cost-Effectiveness: Compared to the trillions needed for a full green energy transition, SAI is estimated to cost between $18 billion and $27 billion per year using modified aircraft.
Life-Saving Potential: Some studies suggest SAI could save up to 400,000 lives annually by reducing heat-related mortality in the world’s hottest regions.
Glacial Preservation: By lowering surface temperatures, it could slow sea-level rise and prevent the melting of land-based glaciers and sea ice.
Reversibility: Unlike permanent carbon storage, SAI effects are temporary; if stopped, the aerosols naturally fall out of the atmosphere within 1โ2 years.5
Potential risks
Termination Shock: If SAI is suddenly stopped (due to war, terrorism, or political collapse) while greenhouse gases are still high, the planet would experience a catastrophic and rapid temperature spike.
Ozone Depletion: Injecting sulfates can damage the stratospheric ozone layer, increasing harmful UV radiation and risks of skin cancer.
Disrupted Weather Patterns: Models indicate it could cause regional droughts, specifically by weakening the South Asian monsoon and reducing tropical rainfall.
Ocean Acidification: SAI only masks temperature; it does not reduce CO2 levels. The oceans would continue to absorb carbon, leading to acidification that destroys coral reefs and marine life.
Moral Hazard: The availability of a “quick fix” might reduce the political and corporate incentive to actually cut greenhouse gas emissions.
Geopolitical Conflict: There is no international governance for SAI. A single country could “control the thermostat,” potentially leading to global conflict if their actions cause weather disasters elsewhere.
Ecological Impacts: Reduced direct sunlight could decrease crop yields and interfere with solar power generation.6
After a few warm and dry weeks, heavy precipitation returned to the West Coast States this past week; however, the heaviest amounts fell on California, which is almost completely free of dryness and drought. At least 1.5 inches fell on a large part of the state including much of the western tier, the higher elevations, and the northern Valleys. Much larger amounts fell on isolated higher-elevation and orographically-favored locations, with a few spots recording amounts approaching 10 inches (liquid-equivalent). Several feet of snow has piled up on a few spots across the Sierra Nevada, but overall the snowpack in this area remains significantly below normal. Other areas from northwestern California northward through the Cascades and points west also recorded significant amounts of precipitation, ranging from 0.5 to locally 3.0 inches. Similar amounts were more scattered across the rest of the interior West, with the largest totals confined to the highest elevations. As of early Tuesday Feb 17, this precipitation has not significantly boosted snowpack in some areas with less than normal amounts, specifically much of the Cascades, south-central Idaho, Scattered locations across western Wyoming, much of west-central and southwestern Colorado, central sections of Utah and Nevada, and the southernmost Rockies.
Farther east, moderate precipitation was fairly widespread over approximately the southeastern quarter of the contiguous states, east of the High Plains and from the central Great Plains, lower Ohio Valley, and mid-Atlantic region southward. Heavier amounts fell on scattered areas across the east-central and southeastern Great Plains, parts of the adjacent lower Mississippi Valley, and a few narrow swaths across the western Florida Panhandle and parts of the northern Peninsula. To the north, scattered light amounts with isolated moderate totals were recorded in upstate New York and parts of New England. Other areas across the High Plains and the northeastern quarter of the contiguous states reported little or no precipitation.
Some areas of improvement were introduced based either on this past weekโs precipitation or a re-assessment of the effects from earlier storms. Specifically, improvements were introduced in central Idaho, the southwestern High Plains, and parts of the Tennessee, lower Ohio, and middle Mississippi Valleys. There was more deterioration than improvement overall, however, including areas scattered across the Eastern Seaboard, lower Mississippi Valley, Deep South, Upper Midwest, northern High Plains, and far southern Texas. Hawaii experienced areas of improvement for the second consecutive week while Alaska and most dry areas in Puerto Rico remained unchanged…
Moderate to locally heavy precipitation fell on part of eastern Kansas, and scattered light to moderate amounts fell on the rest of the southern tier of the Region. Farther north, however, scant precipitation led to large areas of degradation across a large proportion of Wyoming and central through eastern Montana, with more limited deterioration introduced across parts of Nebraska and South Dakota. This resulted in moderate drought or worse covering a swath across most of Nebraska and adjacent areas westward through most of Wyoming and the northern, central, and western sections of Colorado. Severe drought (D2) or worse is widespread from western Nebraska across the southern tier of Wyoming through northern and central parts of Colorado…

Heavy precipitation was fairly widespread across California, which is currently almost completely devoid of any degree of dryness or drought. Elsewhere, widespread deterioration was introduced across central and eastern Montana, leaving most of the state entrenched in abnormal dryness to severe drought (D0 to D2), with an area of extreme drought in parts of north-central Montana. Elsewhere, only minor adjustments were made as light to moderate precipitation fell on a large part of the areas of dryness and drought โ enough to preclude widespread deterioration, but not sufficient to justify much improvement. Only a few parts of central and south-central New Mexico were improved, primarily from the effects of precipitation prior to last week. Severe to extree drought (D2-D3) now extends across most of the western half of New Mexico, adjacent4 Arizona, central and northern Utah, parts of northern and southwestern Idaho, and parts of Pacific Northwest east of the Cascades…
Heavy precipitation (3 to locally 5 inches) dropped on a swath through central Arkansas while 1.5 to locally 3.0 inches were recorded from the lower Red River (south) Valley through the central tier of Arkansas into much of western Tennessee. Moderate to locally heavy amounts were observed over much of the west side of the lower Mississippi Valley and portions of eastern Texas. Amounts of several tenths of an inch to locally around an inch were reported across a large part of central and north-central Texas, most of Oklahoma east of the Panhandle, much of Mississippi and western Alabama, and eastern sections of Tennessee. Little or no precipitation was reported across the Texas and Oklahoma Panhandles, western Texas, and Deep South Texas. This pattern supported improvement across the western half of Tennessee and smaller areas of Arkansas and northwestern Mississippi, along with scattered spots across southern Oklahoma. Deterioration was fairly common in areas that missed most of the weekโs precipitation, primarily in the lower Mississippi Valley, the immediate ArkLaTex region, and Deep South Texas. Intensifying dryness in the latter area prompted the introduction of exceptional drought (D4) in parts of Jim Hogg and Brooks Counties. D4 already existed in part of interior northeastern Arkansas and the southernmost reaches of the Texas Big Bend. Meanwhile, extreme drought (D3) expanded to cover most of south-central and Deep South Texas, parts of east-central Louisiana and adjacent Mississippi, portions of southern Oklahoma and northeastern Texas, most of northeastern Arkansas, and a few smaller scattered areas in western Arkansas and northeastern Oklahoma. During the past 90 days, fewer than 2 inches of precipitation have fallen on western Oklahoma, the Texas Panhandle, and the southwestern tier of Texas from the Big Bend into much of Deep South Texas…
Looking Ahead
The heaviest precipitation over the next few days is forecast along and near part of the West Coast, with at least 2 inches expected across northwestern California, the southern Cascades, and the central and northern Sierra Nevada. Up to 7 inches may fall in isolated higher elevations, most or all of which would be snow. Meanwhile, moderate to heavy amounts (0.5 to 2.0 inches) are forecast across Washington and Oregon from the Cascades westward. Similar amounts are forecast for the northern Great Lakes, and most locations from the Deep South through central New England, with lesser amounts expected over much of the central and northern Carolinas. There is a lot of uncertainty in this area, depending on the development and track of an East Coast storm system that could affect the mid-Atlantic and lower Northeast over the weekend. Light to moderate totals are anticipated over a large part of the interior West, including the Great Basin, much of the northern Intermountain West, and the higher elevations across the Rockies. Several tenths of an inch are possible across the lower Great Lakes, middle and lower Ohio Valley, and the east side of the lower Mississippi Valley. Little or no precipitation is expected across the northern and southern Plains, southern Florida, and northern Maine. Above-normal temperatures are expected from the Southwest through most of the Plains, with many locations expected to average 5 to 11 deg. F above normal. In contrast, subnormal temperatures are forecast in the northernmost Plains, where daily highs could average as much as 9 deg. F below normal. Meanwhile, 5-day average anomalies are expected to range from -2 to -5 deg. F across northern California as well as the Ohio Valley and many locations farther east.
The 6- to 10-day outlook for February 24-28 depicts increased chances for below-normal precipitation across much of the southern tier of the contiguous U.S., from the extreme southern Rockies through the central Gulf Coast and most of Florida. Chances for abnormal dryness exceed 40 percent across most of Texas and some adjacent areas. Farther north, heavier than normal precipitation is at least nominally favored from the mid-Atlantic, southern Appalachians, central Plains, and Desert Southwest northward to the Canadian border. Chances for unusually unsettled weather exceed 60 percent across central and northern California, and top 50 percent central California northward across western Washington and Oregon, as well as the middle and lower Ohio Valley. In Alaska, drier than normal conditions are favored along western parts of the state while surplus amounts are more likely over eastern areas. Across Hawaii, above-normal amounts are marginally favored statewide. Meanwhile, warmer than normal weather is expected to dominate the contiguous 48 states from the Appalachians to the Intermountain West, with chances for significantly warmer than normal conditions topping 80 percent in western Texas. Areas somewhat favoring below-normal temperatures are restricted to the West Coast west of the Cascades, and over much of the Florida Peninsula. Considerably higher chances for unusually cold weather cover most of Alaska, reaching above 70 percent in southwestern parts of the state. In contrast, warmer than normal conditions are somewhat favored across Hawaii, especially across Kauai, Oahu, and the southern Big Island.

The Bureau of Reclamationโs latest forecast for the Colorado River predicts Lake Powell will โmost probablyโ drop below the critical minimum power pool level before the end of this year, jeopardizing Glen Canyon Damโs structural integrity. In the worst-case scenario, it would do so before summerโs end. This could force the feds to operate the dam as a โrun-of-the-riverโ operation to preserve the damโs infrastructure and hydropower output, which would significantly diminish downstream flows and threaten Lower Basin water supplies.
Valentines Day wasnโt so lovey-dovey on the Colorado River.
First, the Bureau of Reclamation (BoR) released a grimmer-than-ever spring runoff forecast for the Colorado River and its two big reservoirs. Then the seven Colorado River Basin states announced that they once again had failed to reach an agreement on a plan to bring demand into line with diminishing supplies by the Feb. 14 deadline. While the states have blown by other deadlines since negotiations began in 2022, this time was different in that it triggered the federal government to move forward to impose a post-2026 management plan of its own.
On paper, the states still have until the end of the water year, or Oct. 1, to come up with a deal or to implement an alternate plan. But that may be too little too late to keep Lake Powellโs surface level from dropping below minimum power pool โ otherwise known as de facto dead pool โ later this year. While the negotiations are over the Colorado River, or rather the water in the river, in many ways they pivot around the need to keep Lake Powellโs surface level above 3,500 feet in elevation. That can only be done by releasing less water out of Glen Canyon Dam, or increasing flows into the reservoir, or a bit of both.
The sticking point in the negotiations hinges upon whether the Upper Basin states will take mandatory and verifiable cuts in water use. The Lower Basin states have already taken cuts, and have agreed to take more, but only if the Upper Basin does the same.
Theย Upper Basinย (aka the Headwaters states) points out that while the Lower Basin has maxed out and even exceeded its Colorado River Compact allocation of 7.5 million acre-feet per year, the Upper Basin hasnโt even come close to using all of the water itโs entitled to. Furthermore, Upper Basin water users, especially those with more junior water rights, have grappled with drastic reductions during dry years because the Upper Basin lacks large reservoirs for storing water, meaning their water use is dictated in large part by the riversโ flows. In 2021, for example, many southwestern Colorado farms had their ditchesย cut off as early as June, forcing them to sit the season out.
The Lower Basin states long used their entire 7.5 MAF allocation and then some, while the Upper Basin states use only about 4 MAF per year. In recent years, Arizona and California have cut consumptive use. Source: Bureau of Reclamation.
Itโs also far simpler logistically to reduce consumption in the Lower Basin, where huge water users are served by a handful ofย very large diversions, such as the Central Arizona Project canal (which carries water to Phoenix and Tucson), the All-American Canal (serving the Imperial Irrigation District โ the largest single water user on the entire river), and the California Aqueduct (serving Los Angeles and other cities), all of which are fed by Lake Mead and other reservoirs. Dialing back those three diversions alone could achieve the necessary water use reduction. The Upper Basin, on the other hand, pulls water from the river and its tributaries via hundreds of much smaller diversions; achieving meaningful cuts would require shutting off thousands of irrigation ditches to thousands of small water users under dubious authority. (ed. emphasis mine]
Also, proposals to divert and consume more of the Colorado Riverโs water โ such as the Lake Powell pipeline โ remain on the table, albeit tenuously. If that project were to be realized, which is a big if these days, it would further drain Lake Powell and result in even less water flowing down to the Lower Basin.
The Imperial Irrigation District is the largest single water user on the Colorado River by far. Most of that water goes to irrigating agriculture, including a fair amount of alfalfa and other forage crops. Las Vegas uses about one-tenth the amount of water as the IID. Source: Bureau of Reclamation.
Environmental groups tend to side with the Lower Basin on this issue. If the Upper Basin is forced to pull less water from the river, it would leave more water for the river, riparian ecosystems along the river, and aquatic critters. The Upper Basinโs proposal to release a percentage of the riverโs โnatural flowโ from Glen Canyon Dam wouldย leave less water in the Colorado River through the Grand Canyon, possibly imperiling endangered fish and rafting.
Meanwhile, the statesโ lack of consensus pushes Glen Canyon Dam closer to the brink of deadpool.
The BoRโsย โPost-2026 Operational Guidelines and Strategies for Lake Powell and Lake Meadโย offers five alternative scenarios for how to run the river. While it doesnโt give a โpreferredโ alternative, officials have indicated that without all of the statesโ approval or congressional action, they are only authorized to go with the Basic Coordination Alternative. That would include a minimum annual release of 7.0 million acre-feet from Glen Canyon Dam, with the largest mandatory cuts being borne by Arizona. But according to the BoRโs latest 24 month projection, that release level would lead to Lake Powellโs surface level dropping below minimum power pool by the end of this year, which is aย really big problem.

Back in 2022, as climate change continued to diminish the Colorado Riverโs flows and Lake Powell shrunk to alarmingly low levels, the damโs operators were faced with the prospect of having to shut down the penstocks, or water intakes for the hydroelectric turbines, and only release water from the river outlets lower on the dam. Not only would this zero out electricity production from the dam, along with nixing up to $200 million in revenue from selling that power, it might also compromise the dam itself. โGlen Canyon Dam was not envisioned to operate solely through the outworks for an extended period of time,โ wrote Tanya Trujillo, then-Interior Department assistant secretary for water and science, in 2022, โand operating at this low lake level increases risks to water delivery and potential adverse impacts to downstream resources and infrastructure. โฆ Glen Canyon Dam facilities face unprecedented operational reliability challenges.โ
In March 2024, a BoR technical decision memorandum verified and clarified those risks, and recommended that dam operators โnot rely on the river outlet works as the sole means for releasing water from Glen Canyon Dam.โ
The only way to do that is to keep the water level above 3,490 feet in elevation, which could mean shifting Glen Canyon Dam to aย run of the river operationย โ where releases equal Lake Powell inflows minus evaporation and seepage โ as soon as this fall. That, most likely, will lead to annual releases far below 7 million acre-feet, which will then lead to Lake Meadโs level being drawn down considerably as the Lower Basin states rely on existing storage to meet their needs, thereby threatening Lower Basin supplies. Such a scenario is clearly not sustainable, would put the Upper Basin states in violation of the Colorado River Compact1, and would almost certainly lead to litigation.
An irony here is that Glen Canyon Damโs primary purpose is to allow the Upper Basin to store water during wet years and release it during dry years, enabling it to meet its Compact obligations. Hydropower, silt control, and recreation were secondary purposes. Now the need to preserve the dam could cause the Upper Basin to run afoul of the Compact. Aridification is rendering the dam obsolete, at least as a water storage savings account. Meanwhile, low levels are diminishing hydropower and recreation. It seems that soon, the damโs main purpose will be to prevent Lake Mead from filling up with silt. [ed. emphasis mine]
Mother Nature, or Mother Megadrought, if you prefer, has left few options for moving forward. The states still could come to an agreement, but itโs difficult to see how, given the long-running stalemate so far. The feds could reengineer Glen Canyon Dam to allow for sustained, low-water releases. That would only be a temporary fix, however, unless climatic trends reverse themselves and the West suddenly becomes much wetter and cooler. Somehow, that doesnโt seem too likely.

Is all of this Colorado River talk a bit confusing? Do you find yourself lost in the water-wonk weeds? Yeah, me too.ย Thatโs why I put together theย Land Deskโsย Colorado River glossary and primer. Itโs not behind the paywall yet, so even you free-riders can take a look for the next few days. Itโs worth looking at even if you already received the email edition last month, because it is now updated with new terms and more graphics (it didnโt all fit in the email version). Iโll keep updating it, too, as new questions about what it all means come up. And if youโre not already, you should consider becoming a paid subscriber and break down the archive paywall, allowing you to read the whole list of analysis, commentary, and data dumps Iโve done on the Colorado River over the last five years.
1 The Upper Basin and Lower Basin generally disagree on how to interpret the Colorado River Compactโs provision dictating that the Upper Basin โnot cause the flow of the river at Lee Ferry to be depleted below an aggregate of 75 million acre-feetโ for any 10-year period. The Upper Basin sees it as a โnon-depletion obligation,โ meaning they canโt exceed their 7.5 MAF/year allocation if it causes the Lee Ferry flow to fall below a 7.5 MAF/year average. The Lower Basin believes itโs a โdelivery obligation,โ and that the Upper Basin must deliver 7.5 MAF/year no matter what. Which interpretation is correct determines whether run-of-the-river would violate the Compact or not.

Negotiators from the seven states along the Colorado River blew pastย yet another federal deadlineย over the weekend without reaching a compromise on how to share its water โ even as this winterโsย dismal snowpackย could spell immediate disaster for the river system.
Westwide SNOTEL basin-filled map February 18, 2026.
Years-long discussions about how to split the riverโs shrinking water supply, which is relied upon by 40 million people, remained deadlocked as the Saturday deadline for a final deal came and went. It was a deadline set by the U.S. Department of the Interior. The seven basin states are split into two factions that have not agreed on how to divvy up cuts to water supplies in dry years. The Lower Basin states of Arizona, California and Nevada lie downstream of Lakes Powell and Mead and rely on releases from those reservoirs for water. The Upper Basin states โ Colorado, Wyoming, Utah and New Mexico โ are upstream of the reservoirs and primarily depend on mountain snowpack for their water supplies. Leaders from each basin pointed fingers at the other as the deadline passed. Lower Basin negotiators have repeatedly said that Upper Basin states must โshare the painโ and take mandatory cuts in dry years, which have become increasingly common in recent decades. But the Upper Basin states say their water users already take cuts every year because their supplies depend on the amount of water available and are not propped up by supplies in Lakes Powell and Mead. Repeated overuse in the Lower Basin has drained the two reservoirs, theyโve argued.
โWeโre being asked to solve a problem we didnโt create with water we donโt have,โ Coloradoโs negotiator, Becky Mitchell, said in a statement Friday. โThe Upper Divisionโs approach is aligned with hydrologic reality and weโre ready to move forward.โ
The Bureau of Reclamationโs latest forecast for the Colorado River predicts Lake Powell will โmost probablyโ drop below the critical minimum power pool level before the end of this year, jeopardizing Glen Canyon Damโs structural integrity. In the worst-case scenario, it would do so before summerโs end. This could force the feds to operate the dam as a โrun-of-the-riverโ operation to preserve the damโs infrastructure and hydropower output, which would significantly diminish downstream flows and threaten Lower Basin water supplies.
As political leaders unleashed a series of pointed statements Friday, the Bureau of Reclamationย released new projectionsย that show one of the river systemโs major reservoirs could be in peril as soon as this summer. The bureauโs new projections show that, if drought conditions remain dire, Lake Powell could fall so low by the end of July that water would no longer flow through Glen Canyon Damโs hydropower system โย a level called โdead pool.โย Even if snow conditions improve, the reservoir could still reach dead pool in November โ a scenario the bureau dubbed its most probable outcome. Theย Colorado River District, an agency created by the Colorado legislature thatโs based in Glenwood Springs and advocates for Western Slope water needs, said it was disappointing that Lower Basin negotiators walked away from discussions on the day the projections were released.
โWith Lake Powell now quickly approaching dead pool, that decision reflects a continued disconnect from hydrologic reality and a clear refusal to confront the core problem: longstanding Lower Basin overuse,โ the district said Monday in a statement.
Snowpack across the mountains that feed the Colorado River remained dismal in early February. Above Lake Powell, snowpack on Feb. 1 sat at 47% of the median recorded for that time of year between 1991 and 2020. The water year โ which began Oct. 1 โ has so far featured record-setting warmth and limited precipitation,ย according to the National Weather ServiceโsColorado Basin River Forecast Center. That could translate to water supplies at 38% of normal, according to the center. Current projections show inflow into Lake Powell will total a meager 2.4 million acre-feet โ far less than the 7.5 million acre-feet allocated to the Lower Basin in theย 1922 Colorado River Compact.

While climate change and the general lack of precipitation are the most obvious causes of the aridification of the American West, there are other factors taking place in the background that are contributing to this process.

Dust on Snow: Windblown dust from disturbed desert soils and dry lake bedsโsuch as the Great Salt Lakeโsettles on mountain snowpacks. This “dark topcoat” reduces reflectivity (albedo), causing snow to absorb more solar heat and melt up to three to seven weeks earlier than clean snow. This premature runoff often reaches reservoirs when they are already full or when the ground is still too frozen for agricultural use, effectively wasting the “natural reservoir” of the snowpack.1
Vapor Pressure Deficit (VPD): Often described as the “thirst of the atmosphere,” VPD measures the difference between the moisture in the air and how much it can hold. Higher temperatures exponentially increase this demand, sucking moisture directly out of soils and plants even when precipitation levels are normal. In recent years, this “atmospheric thirst” has accounted for roughly 61% of drought severity, outweighing the impact of reduced rainfall.2
Pacific Decadal Oscillation Stagnation: The “PDO” is a long-term ocean temperature pattern that typically flips every 20 years. Since the 1990s, it has remained stuck in a “negative phase,” which brings cooler water to the eastern Pacific and pushes moisture-bearing storms farther north, away from the Southwest. Recent research suggests this prolonged “stuck” phase may be driven by human-caused aerosol and greenhouse gas emissions.3
Soil and Vegetation Feedbacks: Aridification creates a self-reinforcing cycle. As soils dry out, they lose the cooling effect of evaporation, causing solar radiation to heat the ground and the air even further. Additionally, while higher CO2 levels can make plants more water-efficient, this gain is often offset by longer growing seasons and increased plant growth, which ultimately draws more total moisture from the soil through transpiration.4
Land Use and Soil Degradation: Intensive land uses, including livestock grazing and urbanization, remove protective vegetation and destabilize soil. This not only increases wind erosion (leading to more dust-on-snow events) but also reduces the soil’s ability to absorb and retain what little moisture does fall, intensifying the “baking” of the landscape.5
Invasive plants: Cheatgrass, tamarisk, and Russian olive are invasive plants most often named as contributors to the aridification of the American West. Cheatgrass transforms diverse, deepโrooted native shrubโgrass communities into shallowโrooted, flammable annual monocultures that dry and senesce early, it depletes shallow soil moisture sooner in the growing season, and dramatically increases fire frequency. It creates a cheatgrassโwildfire feedback loop that repeatedly removes perennial vegetation, reduces soil organic matter and carbon storage, accelerates erosion, and leaves soils warmer, drier, and less able to retain water, so landscapes lose both plant cover and hydrologic function and effectively behave more like a hotter, drier, impoverished system even when longโterm precipitation totals have not changed.6
Like much of the West, Coloradoโs water future will be shaped by a warming climate, population growth, and subsequently increasing competition for finite supplies. In conversations about managing our coveted Colorado River headwater resources, it is easy to assume the most influential voices belong to the well-represented on the population-dense Front Range or the well-funded interests far downstream. Yet some of the most consequential water decisions play out in small mountain valleys, often with limited staff, limited funding, and limited political clout.
It was in that context, despite the Great Recession of 2008, that voters approved the creation of Pitkin County Healthy Rivers that November, a sales tax-funded program with a simple but ambitious mandate: protect and enhance the rivers and streams of the Western Slopeโs Roaring Fork Watershed on behalf of the people and the environment.
What few imagined at the time was that this small, locally funded program would become such an effective way to ensure the people and their cherished rivers had a seat at the table in complex, high-stakes water discussions. A โseatโ that is not symbolic; itโs practical, persistent and sometimes uncomfortable. Because having local voices is not a luxury โ it is essential.
The Power of Showing Up
Healthy Riversโ influence begins with showing up. Showing up ready to listen and engage, recognize partners and advance and fiscally sponsor new alliances, all while emphasizing local knowledge, data, and community-backed priorities. In basin-wide planning efforts, feasibility studies, and project negotiations, Healthy Rivers represents local, place-based interests that might otherwise get overshadowed by far more powerful players, be they up or downstream.
This has meant actively seeking valuable connections, therefore knowledge, daresay wisdom, with hopes of earning a voice that ensures headwaters perspectives are considered at these tables. Think Colorado Basin Roundtable, U.S. Forest Service, Colorado Parks and Wildlife, the Colorado Water Conservation Board, local and nearby watershed groups, and other environmental non-profits. This outreach has led to critical partnerships and heightened transparency and inclusivity on many water matters. It has also meant supporting technical analyses and funding early-stage studies โ most recently for water-quality monitoring on Lincoln Creek, a tributary to the Roaring Fork โ so local conditions and risks are understood before decisions are made elsewhere.
And because our funding comes directly from local voters, Healthy Rivers advocates from the position of our constituents who overwhelmingly supported its creation. That matters in rooms where water is discussed in acre-feet and complex legal terms, often far removed from community-specific values. This has allowed Healthy Rivers to elevate community priorities in negotiations around watershed health, elevating environmental values like instream flows.
Small Programs, Real Influence
One misconception about many local programs is that they are too small to matter. In practice, Healthy Rivers has demonstrated that being nimble is an advantage. Healthy Riverโs contributions are rarely flashy, but they have been catalytic, having a role in everything from diversion arbitration, instream flow protections, riparian habitat restoration, and water-quality monitoring.
It has done this by supporting projects like technical studies, restoration efforts, and infrastructure improvements that likely wouldnโt have happened otherwise. And by convening unlikely partners, and stepping into conversations early, before positions harden and options narrow.
For example, Healthy Rivers helped support the pursuit of a Recreational In-Channel Diversion (RICD) on the Roaring Fork River, recognizing instream flow rights alongside recreation as legitimate, community-defining values worthy of legal protection. It is supporting a Wild & Scenic designation for the Crystal River, and investing in beaver-related studies in order to inform projects that restore wetlands, reconnect floodplains, and improve late-season flows.
Translating Complexity for Communities
Another core part of having a seat at the table is translation. Colorado water law, hydrology, and planning processes are famously complex. Without intentional effort, these processes can leave local communities feeling confused, disengaged, or shut out of decisions that directly shape their rivers.
Healthy Rivers sees its role as a bridge. It translates technical concepts into plain language, not to oversimplify, but to make participation possible. This has included helping residents understand what designations like โWild & Scenicโ actually do โ and donโt โ mean, or explaining how instream flow rights function alongside agricultural and municipal uses.
This two-way translation strengthens outcomes. Decision-makers gain local context. Communities gain confidence. And water decisions become more durable because they reflect shared understanding, not just legal compliance.
Collaboration Over Confrontation
A seat at the table does not guarantee agreement. Some of the most meaningful work Healthy Rivers does happens in moments of tension, usually when water supply, ecological health, recreation, and private property interests collide.
Our approach is rooted in collaboration, not advocacy for advocacyโs sake. That means listening carefully, acknowledging tradeoffs, and being honest about constraints. But it also means pushing back when local values are at risk of being overlooked. In projects like renovating the Sam Caudill State Wildlife Area, Healthy Rivers worked alongside CPW, Garfield County, and development partners to balance recreation access, public safety, and river protection, demonstrating how infrastructure investments can serve both people and rivers.
Lessons for Other Communities
This role requires patience. Water decisions typically move slowly, and progress often comes in inches rather than miles. And in a basin as complex as the Colorado River system, no one wins by going it alone. Our experience has reinforced a simple truth: collaboration works best when local voices are present early and consistently, not as an afterthought.
While not every community can replicate Pitkin Countyโs funding model, the underlying principles are transferable:
Local funding creates legitimacy. Voter-backed programs carry weight because they represent collective priorities.
Consistency builds trust. Showing up over time and building long term relationships matters.
Data and stories belong together. Technical rigor and real-world experience are stronger together than apart.
Early engagement saves time later. Investing upstream โ literally and figuratively โ reduces conflict downstream.
Healthy Rivers exists to ensure that when decisions are made about the Roaring Fork Watershed, the people who know and love these rivers are part of the conversation. That seat at the table does not guarantee outcomes, but it guarantees presence. And in water, as in so many things, presence is power.
In the 1950s, the U.S. Bureau of Reclamation built the Blue Mesa, Morrow Point and Crystal dams west of Gunnison as part of the massive regional Colorado River Storage Project.

For the first time since its completion in 1966, the Bureau of Reclamation is replacing all four original valves at Blue Mesa Dam, the largest of the three dams that make up the Aspinall Unit on the Gunnison River. This multi-year, $32 million federally funded project is a major milestone in ensuring the reliability and safety of one of Coloradoโs most important water and power facilities.
Standing 390 feet tall, Blue Mesa Dam creates Blue Mesa Reservoir, the largest body of water in Colorado, with a capacity of nearly 941,000 acre-feet. Together with Morrow Point and Crystal dams, the Aspinall Unit provides water storage, flood control and hydropower generation. Blue Mesaโs power plant alone produces 86 megawatts of electricity, helping power homes and businesses across the region.

The project will replace two ring follower gate valves and two butterfly valves, critical components that control how water moves through Blue Mesa Dam.
Ring follower gates, located in the damโs outlet works, allow water to bypass the turbines during maintenance or emergencies, ensuring uninterrupted flows to the Gunnison River.
Butterfly valves, located inside the penstocks, act as flow-control and isolation devices for water entering the turbines to generate hydropower.
Work began in January with the removal of the first ring follower gate, a massive assembly measuring 18 feet long by 7 feet wide and weighing about 14 tons. The hydraulic hoist system adds another 12 tons. Before safely removing the gate, crews first installed a blind flange, a heavy steel plate that temporarily seals the opening and holds back water.
The gate and its components are now in California for refurbishment and will return for installation in August. Later this fall, once irrigation demands ease, the blind flange will be removed and normal operations restored. After this first gate is complete, crews will move on to the second ring follower gate, followed by the two butterfly valves.
โThis work is complex,โ said Blue Mesa Plant Supervisor Eric Langely. โWe must maintain minimum river flows downstream, avoid disruptions at Morrow Point and Crystal dams, and manage drought-related constraintsโall while working inside a dam built nearly 60 years ago.โ
The project is being led by a skilled team of Reclamation engineers, plant operators, and technical specialists. Their expertise ensures this upgrade will keep Blue Mesa Dam operating safely and efficiently for decades to come.

A multi-day storm system is dropping big totals across the western U.S. this week. The Sierra Nevadas are likely to get over 3 feet of new snow, while the Interior Rockies and Cascades will see between 1-2 feet.
72-hour snowfall forecast for the western U.S., as of February 16, 2026. Map from the Weather Prediction Center.
This storm is a welcome relief for many drought-stricken areas, especially given the near record low snowpack so far this season. NRCS snowpack is below to well-below average for most of the west. A startling number of SNOTEL sites in Colorado and Utah are reporting levels below the 5th percentile (meaning they are drier than 95% of historical records for this date).
Current snowpack conditions across the western U.S. as of February 16, 2026. Map from NRCS SNOTEL.
At the Colorado Headwaters, snowpack is record low for this time of year. With only 56 days to go till normal peak snowpack, new accumulations would have to be record-breaking to get the basin to near-average levels. A much below average peak and early melt are much more likely. This has major implications for water supply, agriculture, and wildfire risk across the region.

These concerningly low snowpack accumulations are evident in the Colorado Basin River Forecast Center’s water supply forecasts. The April-July runoff forecast for Lake Powell (the Upper Colorado River Basin’s largest reservoir) is 38% of average, about a 4-million acre-foot deficit.

While we can expect snowpack and forecasted runoff to improve with the current storm, the overall outlook for the season remains concerning. Additional late season snows and colder temperatures could minimize further deteriorating conditions and the risk of large wildfires this summer. Stay tuned over the next couple of months!
Climate tipping points are key thresholds in Earth systems like oceans, ice sheets, and forests, where warming can push the climate into a new state. Once crossed, these changes can be hard to reverse and can start a chain reaction that affects ecosystems, weather extremes and the global climate. Credit: ESA
If you think of Earthโs climate system as a backyard swing thatโs been gently swaying for millennia, then human-caused global warming is like a sudden shove strong enough to disrupt the usual arc and buckle the chains.
And if humans keep heating the planet with greenhouse gas pollution, the climate swing could lock Earth into a hothouse trajectory, as parts of the system feed on their own momentum, even if emissions are reduced later, an international team of scientists warned Wednesday in a new paperpublished in the journal One Earth.
Their analysis covers 16 key Earth systems, including oceans, ice sheets and forests, that are likely to destabilize if the planet continues to warm. If large parts of the Amazon rainforest and tropical coral reefs die, they absorb less carbon dioxide, triggering a dangerous chain reaction of warming.
If Earthโs climate starts on a hothouse trajectory, it would represent a โglobal tipping pointโ as the heating sustains itself even if greenhouse gas emissions drop, said lead author William Ripple, a distinguished professor of ecology at Oregon State University and a leading researcher on climate tipping points.
In the backyard, thatโs the moment when the push is so hard that the swing hesitates at the top, just long enough to show that the ride may not be under control anymore and the chains are being tested.
โWhat typically took thousands of years is now happening in decades,โ Ripple said, adding that human-caused warming is already nudging the climate system out of 11,000 years of relative stability with good conditions for farming and societal development.
Earth could be entering a period of unprecedented climate change on a one-way trajectory, in which processes such as ice-sheet collapse can continue even if the average global temperature is stabilized, he said.

Recent observations suggest that the climate may be responding more strongly than some models predicted, Ripple added. โWe are concerned that policymakers and the public may not yet be aware of these recent developments.โ
In late January, another group of leading climate scientists urged policymakers to adopt a climate goal of limiting human-caused warming to 1 degree Celsius above the pre-fossil fuel era, which is more ambitious than the 1.5 to 2 degrees Celsius target set in the Paris Agreement. Theyโve also recently reported that Earth is losing its reflective sheen, which amplifies warming, and that key ocean currents are changing in ways that destabilize the entire global climate system.
But itโs not clear if the scientific warnings are making a difference in โa post-truth era in which too many people prefer pleasant lies over unpleasant truths,โ said Reinhard Steurer, a professor of climate policy and governance at the University of Natural Resources and Life Sciences in Vienna who studies how climate science and policy interact. He said that new studies outlining disastrous scenarios are unlikely to have much impact in the current political climate, but that researchers should keep speaking out, and not surrender to โtechno illusions or hopium.โ
The authors of the new paper stressed that a self-sustaining hothouse trajectory is not the same as a Hothouse Earth state, which would be when the global climate rebalances at a much hotter average temperature.
No Good Analog Climates
Instead of offering a single new climate forecast, the paper synthesizes decades of research revealing how different parts of the climate system influence one another. When one part of the system is destabilized, they wrote, it can amplify stress in others, pushing the planet along a self-reinforcing warming pathway.
Earth has had hothouse climates in the ancient geological past. But the authors of the new paper said there may not be a parallel to whatโs happening now, at least not during the past 3 million years, co-author Johan Rockstrรถm, co-director of the Potsdam Institute for Climate Impact Research, said via email.
That amount of warming goes beyond current expectations and would devastate ecosystems and communities globally. Many other current climate projections suggest that, under current policies, warming would level off somewhere between 2.7 and 3 degrees Celsius.
Human-caused warming is happening much faster than any other warming documented in the paleoclimate record, and itโs also unprecedented because itโs driven by a single dominant force, Rockstrรถm added: human greenhouse gas emissions. Under these conditions, research has documented that Earth is already losing some of the natural buffers that dampened climate swings in recent millennia.
โWe now see worrying signs that the Earth system is losing resilience,โ Rockstrรถm said. Recent extremes, he added, are a sign that the climate system โmay respond more strongly to the same amount of warming than it did before.โ

Key Points
The seven Colorado River Basins states failed to reach a shortage-sharing agreement in time for a Feb. 14 deadline set by the federal government.
State officials say negotiations have yielded “almost no headway” toward a compromise over who will give up water.
The Interior Department has said it will impose its own plan, but that prospect could trigger a lengthy legal battle as states move to protect their water allocations.
The prospect of a costly and prolonged interstate lawsuit over rights to the Colorado River looms now that the states using the water are blowing past a Valentineโs Day deadline with no water-sharing deal in hand. With no agreement among the states, Interior Secretary Doug Burgum said the federal government could no longer delay action andย would move forwardย with work onย a set of alternativesย outlined late last year.
โNegotiation efforts have been productive,” Burgum said in a statement Feb. 14. “We have listened to every stateโs perspective and have narrowed the discussion by identifying key elements and issues necessary for an agreement. We believe that a fair compromise with shared responsibility remains within reach.”
[…]
The dispute has largely hinged on whether states in the headwaters region would agree to mandatory cuts [ed. no one has the authority to order mandatory cuts in Colorado and likely in the entire upper basin] to their overall supply in especially dry years โ a commitment they have so far rejected in part because they do not use their full allocation as the more developed Southwest does…
“As I talk with people throughout Southern Nevada, I hear their frustration that years of negotiations have yielded almost no headway in finding a path through these turbulent waters. As someone who has spent countless nights and weekends away from my family trying to craft a reasonable, mutually acceptable solution only to be confronted by the same tired rhetoric and entrenched positions,” [John] Entsminger said, “I share that frustration.”
The U.S. Bureau of Reclamation has released a February 24-month study showing inflow to Lake Powell declining by 1.5 million acre-feet since January as the federal agency highlights the worsening hydrologic conditions across the Colorado River Basin.
The study of the most probable forecast for the Colorado River under current conditions was released on Friday, just as the seven compact states remained at a stalemate and failed to meet a Feb. 14 deadline for agreement on how to reduce their own usage of water to save the river.
U.S. Interior Secretary Doug Burgum announced on Saturday, Feb. 14, that the federal government is moving forward with finalizing operating guidelines for the Colorado River reservoirs by Oct. 1. His announcement adds pressure to Colorado and the other compact states to find compromise or face guidelines forced onto them by the federal government.
โWhile the seven Basin States have not reached full consensus on an operating framework, the Department cannot delay action,โ the U.S. Bureau of Reclamation said in its announcement that the federal government was moving forward.

The lack of agreement among the compact states and the idea of federal intervention raises the prospect of litigation that would be drawn out and ultimately end with the U.S. Supreme Court. The current Rio Grande Compact dispute between Texas and New Mexico that has taken 12 years to reach a proposed settlement, now filed with the U.S. Supreme Court, gives an indication to the slow-evolving nature of U.S. water law.
โI am disappointed that the seven Basin States could not reach a consensus agreement on the future management of the Colorado River by the U.S. Department of the Interiorโs Feb. 14 deadline,โ said Colorado Attorney General Phil Weiser, who added that Colorado is prepared for litigation to protect Coloradoโs rights and interests.
โColorado will continue to work with our fellow Upper Division States to provide comments on the federal governmentโs draft environmental impact statement, which sets forth a range of possible solutions. The Upper Division States will have to cut back their usage of water from the Colorado River โ by 40 percent or more โ in the face of an historic drought,โ he said.
U.S. Sen. John Hickenlooper said the low snowpack this winter is adding an exclamation point to the dire conditions of the Colorado River Basin. โIf we donโt address this problem together โ head-on and fast โ our communities, farms, and economies will suffer,โ Hickenlooper said.
โThe best path forward is the one we take together. Litigation wonโt solve the problem of this long-term aridification. No one knows for sure how the courts could decide and the math will only get worse.โ
BLMโs February 24-month study shows a loss of 1.5 million acre-feet is equivalent to approximately 50 feet in elevation in Lake Powell.
โThe basinโs poor hydrologic outlook highlights the necessity for collaboration as the Basin States, in collaboration with Reclamation, work on developing the next set of operating guidelines for the Colorado River system,โ said Acting BLM Commissioner Scott Cameron. โAvailable tools will be utilized and coordination with partners will be essential this year to manage the reservoirs and protect infrastructure.โ
The water year inflow is now estimated at just 52 percent of average, and as a result, the February 24-Month Study projects, for the first time, that Lake Powell could decline (based on most probable projections) to:

The water year inflow is now estimated at just 52 percent of average, and as a result, the February 24-Month Study projects, for the first time, that Lake Powell could decline (based on most probable projections) to:
3,490 ft โ minimum power pool in December 2026; below this level Glen Canyon Damโs ability to release water is reduced and it can no longer produce hydropower.
3,476 ft โ in March 2027; the lowest elevation on record since filling further constraining the ability to release water from Glen Canyon Dam.
Colorado River managers estimate that around 4 million acre-feet of cuts are needed to bring the basin back into balance โ an amount equal to more than a quarter of the Colorado Riverโs annual average flow.
โThere needs to be unbelievably harsh, unprecedented cuts,โ Brad Udall, a senior water and climate research scientist at the Colorado Water Center, told The Guardian media outlet.
โMother Nature is not going to bail us out,โ Udall said.

Flows in the Colorado River are down 20 percent over the last century and precipitation has shrunk by about 7 percent with rising temperatures as aridification takes hold across the southwest.
โThe chickens are coming home to roost,โ Udall said. โClimate models have underestimated how much warming we are going to get, and humans are not stepping up.โ
Jack Schmidt, director of the Center for Colorado River Studies at Utah State University, likened the negotiations among the seven compact states to the final scene in โThelma and Louise.โ โSeven people have their hands on the steering wheel driving toward the edge of a cliff โ and no one is working the brakes,โ he reportedly said.

The Department of the Interior is moving forward with the Post-2026 NEPA process to finalize operating guidelines for Colorado River reservoirs by Oct. 1, 2026. While the seven Basin States have not reached full consensus on an operating framework, the Department cannot delay action. Meeting this deadline is essential to ensure certainty and stability for the Colorado River system beyond 2026.
โNegotiation efforts have been productive; we have listened to every stateโs perspective and have narrowed the discussion by identifying key elements and issues necessary for an agreement. We believe that a fair compromise with shared responsibility remains within reach,โ said Secretary of the Interior Doug Burgum. โI want to thank the governors of the seven Basin States for their constructive engagement and commitment to collaboration. We remain dedicated to working with them and their representatives to identify shared solutions and reduce litigation risk. Additionally, we will continue consultations with Tribal Nations and coordinate with Mexico to ensure we are prepared for Water Year 2027.โ
Prolonged drought conditions over the past 25 years and the most recent forecast showing inflow to Lake Powell declining by 1.5 million acre-feet since January underscore the ongoing challenges. The inflow reduction could result in Lake Powell dropping to an extremely low level, threatening water delivery and power generation.
The Colorado River is managed and operated under compacts, federal laws, court decisions and decrees, contracts and guidelines known collectively as the โLaw of the River.โ This apportions the water and regulates the use and management of the river among the seven Basin States โ Arizona, California, Colorado, Nevada, New Mexico, Utah, and Wyoming โ and Mexico. The Colorado River Compact is the cornerstone of the โLaw of the River.โ The 1944 Treaty with Mexico governs the sharing of the Colorado River between the two nations.
The Colorado River is a vital resource as it provides economic stability and enhances the quality of life across the basin. The river:
provides water to approximately 40 million people for municipal use.ย
supports the generation of hydroelectric energy, producing more than 8 billion kilowatt-hours annually powering the needs of approximately 700,000 homes.
sustains 5.5 million acres of farmland and agricultural communities where a significant share of the fruit and vegetables consumed in the United States are grown.ย
serves as a vital resource for 30 Tribal Nations and two Mexican states.
supports seven National Wildlife Refuges, four National Recreation Areas, and 11 National Parks.ย
โThrough collaboration among the Department and Reclamation, states, Tribal Nations, Mexico and other key partners, we can create more opportunities for innovation and develop stronger tools to address drought and growing water demands,โ said Assistant Secretary – Water and Science Andrea Travnicek. โWorking together ensures that we combine expertise and resources to build solutions that benefit everyone and secure the future of the Colorado River.โ

I met John Leary in the parking lot of a Tractor Supply in Rangely Colorado. There was something about the vehicles in that lot that made me think it might not be the best place to park a Toyota Yaris with California plates, so I parked around the corner, then moved my video gear into the back of John’s white utility truck.
John is a Senior Restoration & GIS Project Manager at RiversEdge West, a non-profit organization that’s leading the White River Partnership – a coalition of public, private, and nonprofit entities that are working to conserve and to restore riparian ecosystems along the White River and its tributaries.1
John had volunteered to show me some of the restoration work he and his teams had been doing on the riverbanks west of Rangely. The river had officially been designed as being “over-appropriated” in 2025. When a river is classified as being over-appropriated, it means that the total amount of water legally promised to water rights holders exceeds the supply of water that’s available in the river system at some or all times of the year.2 The designation acts as a formal recognition of water scarcity, where the demand for water is higher than the supply, often exacerbated by drought, climate change, and increased development.
John and his teams were working to reduce the number of invasive tamarisk and Russian olive trees that had crowded the White River’s banks, at the expense of wildlife and native vegetation like willows and cottonwoods. One of the methods John and his teams used was the application of tamarisk beetles. Tamarisk beetles originated in Eurasia – specifically central Asia, China, Kazakhstan, Greece, Uzbekistan, and Tunisia, and were introduced to North America as a biological control agent for invasive tamarisks. The beetles defoliate tamarisk trees by feeding on their leaves and on new growth, until the trees either weaken or die altogether.3
Since their introduction tamarisk beetles have spread across the Western U.S., including Nevada, Utah, Colorado, and even parts of Arizona, and in some areas have resulted in an 80% mortalityrate for the invasive tamarisks.4 This removal method sounds better than what I witnessed in California’s Coachella Valley, where miles of tamarisk trees had been intentionally burned by the Southern Pacific Railroad – which planted the trees in the early 1900s to keep sand off their railroad tracks.5

John and I drove west along the river and then finally parked. We hiked to a spot where John showed me a stand of native cottonwoods had sprouted up after his team removed tamarisks which had previously occupied that area. During the interview I filmed with John he repeatedly credited RiversEdge West and their partners in the White River Partnership, which included the Bureau of Land Management, Canyon Country Discovery Center, Colorado Northwestern Community College, Colorado Parks and Wildlife, State of Utah School and Institutional Trust Lands Administration, Town of Meeker, Colorado,Town of Rangely, CO, Uintah County Utah, Utah Conservation Corps, Utah Division of Wildlife Resources, Utah State University, Western Colorado Conservation Corps, the White River Alliance, and most importantly many ranchers and private land owners who supported the restoration efforts being carried out on their own riverfront property.6
The operation of Lake Powell and Lake Mead in the February 2026 24-Month Study is pursuant to the December 2007 Record of Decision on Colorado River Interim Guidelines for Lower Basin Shortages and the Coordinated Operations of Lake Powell and Lake Mead (Interim Guidelines),1ย the Supplemental Environmental Impact Statement for Near-term Colorado River Operations Record of Decision (2024 Interim Guidelines SEIS ROD),2ย and reflects the 2026 Annual Operating Plan (AOP). Pursuant to the Interim Guidelines, the August 2025 24-Month Study projections of the January 1, 2026, system storage and reservoir water surface elevations set the operational tier for the coordinated operation of Lake Powell and Lake Mead during 2026.
The August 2025 24-Month Study projected the January 1, 2026, Lake Powell elevation to be less than 3,575 feet and at or above 3,525 feet and the Lake Mead elevation to be at or above 1,025 feet. Consistent with Section 6.C.1 of the Interim Guidelines, and Section 6.E of the 2024 Interim Guidelines SEIS ROD, the operational tier for Lake Powell in water year (WY) 2026 is the Mid-Elevation Release Tier and the water year release volume from Lake Powell is projected to be 7.48 million acre feet (maf). To protect a target elevation at Lake Powell of 3,525 feet, adjustments to Glen Canyon Dam monthly volume releases have been incorporated into the December 2025 24-Month Study and include an adjusted monthly
release volume pattern for Glen Canyon Dam that will hold back a total of 0.598 maf in Lake Powell from December 2025 through April 2026. 3ย That same amount of water (0.598 maf) will be released later in the water year. Given the hydrologic variability of the Colorado River System, the actual WY 2026 operations, and being consistent with Section 6.E of the 2024 Interim Guidelines SEIS ROD, the projected release from Lake Powell in WY 2026 may be less than 7.48 maf. Consistent with Section 6.E of the 2024 Interim Guidelines SEIS ROD, Reclamation will consider all tools that are available during the interim period to avoid Lake Powell elevation declining below 3,500 feet. The August 2025 24-Month Study projected the January 1, 2026, Lake Mead elevation to be below 1,075 feet and above 1,050 feet. Consistent with Section 2.D.1 of the Interim Guidelines, a Shortage Condition consistent with Section 2.D.1.a will govern the operation of Lake Mead for calendar year (CY) 2026. In addition, Section III.B of Exhibit 1 to the Lower Basin Drought Contingency Plan (DCP) Agreement will also govern the operation of Lake Mead for CY 2026. Lower Basin projections for Lake Mead take into consideration additional conservation efforts under the LC Conservation Program.
Current runoff projections into Lake Powell are provided by the National Weather Serviceโs Colorado Basin River Forecast Center. The observed unregulated inflow into Lake Powell for the month of January was 0.265 maf or 79% of the 30-year average from 1991 to 2020. The February 2026 unregulated inflow forecast for Lake Powell is 0.260 maf or 71% of the 30-year average. The 2026 April through July unregulated inflow forecast for Lake Powell is 2.40 maf or 38% of average. The WY 2026 unregulated inflow forecast for Lake Powell is 5.02 maf or 52% of average.
Due to changing Lake Mead elevations, Hooverโs generator capacity is adjusted based on estimated effective capacity and plant availability. The estimated effective capacity is based on projected Lake Mead elevations. Unit capacity tests will be performed as the lake elevation changes. This study reflects these changes in the projections.

1 For modeling purposes, simulated years beyond 2026 assume a continuation of the 2007 Interim Guidelines including the 2024 Supplement to the 2007 Interim Guidelines (no additional SEIS conservation is assumed to occur after 2026), the 2019 Colorado River Basin Drought Contingency Plans, and Minute 323 including the Binational Water Scarcity Contingency Plan. With the exception of certain provisions related to Intentionally Created Surplus recovery and Upper Basin demand management, operations under these agreements are in effect through 2026. Reclamation initiated the process to develop operations for post-2026 in June 2023, and the modeling assumptions described here are subject to change.
The controversy surrounding Glen Canyon Dam’s River Outlet Works (ROW) centers on a critical design vulnerability: the dam may soon be unable to reliably release water if Lake Powell drops below the minimum power pool (3,490 feet). 1
Aerial photo of the Glen Canyon Dam near Page, Arizona. Photo by Alexander Heilner/The Water Desk, with aerial support by LightHawk.
While the dam usually releases water through high-elevation penstocks to generate hydropower, the ROWโfour 8-foot-wide steel pipesโis theonly way to move water once levels drop too low for the turbines. Recent inspections by the Bureau of Reclamation revealed significant damage to these pipes, including cavitationโa process where high-velocity water creates vapor bubbles that implode, eroding the steel.2
Reliability Gap: The ROW was designed for temporary use (e.g., flood control), not for the continuous, long-term operation that a “dead pool” scenario would require. A March 2024 memo from the Bureau of Reclamation warned that they should not be relied upon as the sole means of sustained water delivery.3
Legal & Economic Threat: If the ROW fails or its capacity is restricted to prevent further damage, the Upper Basin states may be unable to meet their legal obligation to deliver water to 30 million people in the Lower Basin (Arizona, Nevada, California).4
Safety Buffer: Due to the damage, the Bureau recently determined they can only safely operate the ROW at levels at least 24 feet above dead pool (3,370 feet), effectively raising the “failure point” of the dam’s plumbing.5
Proposed Fixes: Environmental groups, such as the Utah Rivers Council, advocate for drilling new, lower-level bypass tunnels around the dam to ensure water can flow even at riverbed levels. However, these modifications are costly and could take over a decade to implement.6

Jay Fetcher and other ranchers in northwest Colorado measure snowpack each winter using their barbed wire stock fences.
A healthy level is called a three wire winter, when the snow piles up past the third wire above the ground. But on Feb. 9, the region was experiencing a zero wire winter.
โWe just have no snow, and I have never seen it, in my 75 years here, I have never seen this,โ Fetcher said Monday as he navigated patches of mud on his ranch in the Elk River valley north of Steamboat Springs.

Many of the hills and meadows surrounding his ranch were brown and bare. The thermostat on Fetcherโs truck read 50 degrees, and the last patch of snow was melting fast off the roof of a barn.
This year, Fetcherโs ranch is on the frontlines of record-low snowpack across the West that is adding a sense of urgency among seven states to finalize a plan for how to conserve the dwindling Colorado River.
The snow in the nearby Zirkel wilderness melts into the Elk River and irrigates Fetcherโs fields before the water eventually joins the Colorado River and flows to millions of people downstream.
But things have been changing near Fetcherโs ranch over the past decade, and it could have implications for states competing for the water supply.
Since 1951, the Fetchers have tracked how long the snow stays on their meadows by marking the date in a little red journal. The data shows the snow is melting sooner in the valley.
โIn the past 10 years, the snow leaving the meadow has moved up by 12 days,โ he said. โThis winter is a real indication of climate change, with bare meadows in the middle of February. I mean, what date am I going to write down for (when) snow left the meadow this year? Did it ever come?โ

The dwindling water supply in the Colorado River basin is driving intense negotiations among the seven states over how to share it in the future. Some forecasts predict water levels at Lake Powell could get so low this year that its dam would stop producing electricity. States have until Saturday to come to an agreement and the pressure has been building.
If they donโt, they might end up fighting each other in the Supreme Court.
Downstream states, including California and Arizona, say Colorado and states in the upper basin should pitch in with mandatory water restrictions during dry years.
But leaders in the Rocky Mountains are digging in.
They say ranchers and cities are already enacting conservation plans, and more cuts should not be forced on them.
โIf we don’t choose how to live within the river’s limits, the river will choose it for us, and she will not be gentle,โ Becky Mitchell, Coloradoโs top river negotiator, said in a speech to a water conference in January. โOperations (of the riverโs reservoirs) must be supply based, not demand based, not entitlement justified, and not built on a hope that the next big year will save us.โ
Negotiators in the lower basin are calling for compromise. J.B. Hamby is Californiaโs water negotiator.
โItโs going to take everyone chipping in and making the necessary (water) reductions to balance the supply with the demand we have moving forward,โ he said during a speech last month.

Sitting on a patio on his ranch in northwest Colorado, Fetcher said Monday heโs not confident the lower and upper basins will resolve their differences anytime soon.
He said heโs willing to donate some water he doesnโt use each year downstream to California, but under current regulations, he would risk losing his water rights under a โuse it or lose itโ system.
โI know that we will be able to irrigate these meadows just fine, because of our water rights, because of where we are, because of the ranch being on the Elk River. So from a personal standpoint, I’m okay with it,โ he said. โThe challenging question is, what happens with the lower basin? They’re just going to have to think about how to get by with less water and not have so many golf courses out there.โ
The deadline for the seven states to agree on a long-term plan for how to conserve the Colorado River is Saturday.

The Lower 48 states and Alaska only saw degradations this week. There was a strong east-to-west temperature gradient again this week, with below-normal temperatures across much of the East and above-normal temperatures across the West. Another week of localized precipitation that missed large portions of the country led to expanding precipitation deficits. Degradations were also scattered across the West, from the Pacific Northwest into the northern and central Rockies, including portions of Oregon, Idaho, Montana, Wyoming and western Colorado. Although some mountain snow fell, critically low snowpack with snow-water equivalent levels below the 15th percentile continues to dominate much of the region and support ongoing drought expansion. Across the High Plains and into the western Midwest, one-class degradations followed another mostly dry week. In the Northeast, despite colder-than-normal temperatures, a continued lack of meaningful precipitation contributed to worsening conditions in parts of Pennsylvania and southern New England. Degradations were also seeing across the South, from the eastern southern Plains of Oklahoma and Texas eastward into the Lower Mississippi Valley and the western Carolinas. Despite scattered precipitation in some locations, short- to mid-term precipitation deficits continue to grow, with drying soils and low streamflows supporting intensification. In southern Georgia and Florida, fire danger continues to rise, with parts of Florida reporting Keetch-Byram Drought Index values between 500 and 700.
In Hawaii, strong trade winds brought heavy precipitation and wind to the windward slopes of Molokai, Maui and the Big Island, where 4 to 10 inches of rain fell at lower elevations and snow at higher elevations, supporting one-class improvements in those areas…
The High Plains saw little to no meaningful precipitation this week, with most of the region receiving less than 25 percent of normal and many locations at or below 5 percent of normal precipitation. Any snowfall was light and offered minimal liquid-equivalent benefit. In eastern Wyoming and eastern Colorado, precipitation deficits continue to deepen with soil moisture percentiles declining, and recent above-normal temperatures led to drying where snow cover is limited. This led to expansion of moderate (D1) and severe drought (D2) across parts of eastern Wyoming and Colorado into the southwest South Dakota, the Nebraska Panhandle and the western Nebraska Sandhills. Similarly, growing short- to medium-term precipitation deficits, below-normal soil moisture percentiles and elevated evaporative demand led to the introduction of extreme drought (D3) to Nebraskaโs Panhandle. Eastern Nebraska also saw the expansion of abnormal dryness (D0) as the lack of precipitation has led to drying conditions. Across Kansas, degradations occurred primarily in the northwest, south and along the Missouri border in eastern Kansas following another dry week which, like the rest of the region, added to the growing precipitation deficits and drying soil moisture…
Colorado Drought Monitor one week change map ending February 10, 2026.
Precipitation across the West this week was light and uneven. Most low-elevation areas in California, Nevada, Arizona, Utah and western Colorado received little to no measurable liquid precipitation, with seven-day totals generally below 0.25 to 0.50 inches. Mountain snow did fall in portions of the northern Rockies and Pacific Northwest, but accumulations were locally light and patchy. Snowpack and Snow Water Equivalent (SWE) percentiles remain well below normal at many SNOTEL sites: much of Oregon, Washington, Idaho, Montana, Wyoming and western Colorado show SWE values in the lowest 15th percentile, with numerous locations in the single digits for this time of year.
Temperatures were above normal across broad areas of the interior West, especially in the Great Basin, central and eastern Wyoming, and northern Colorado, where daytime highs ran 5 to 15 degrees above average at times. These warmer temperatures limited snow accumulation in some basins and contributed to surface drying where snow cover was sparse or absent.
Across the Pacific Northwest, isolated precipitation helped maintain existing conditions in parts of western Washington, Oregon and northern California. However, low SWE percentiles and expanding short- to mid-term precipitation deficits led to the expansion of abnormal dryness (D0) and localized moderate drought (D1) in Washington. Despite seeing precipitation this week, areas of Montana still saw degradations where short- to mid-term precipitation deficits, low soil moisture percentiles and poor snowpack continue to be of concern. Across Utah, Nevada and western Colorado, persistent 2 to 4 month precipitation deficits combined with declining soil moisture and very low SWE percentiles (snow drought) led to further degradations. Many SNOTEL sites in the central Rockies and Great Basin continue to report levels below the 10th percentile for snowpack, with Colorado experiencing its worst snowpack-to-date on record, according to Denver Water and 9NEWS…
Drought conditions across the South continued to deteriorate this week, as much of the region received little to no meaningful precipitation. Most areas recorded below 50 percent of normal rainfall, with many locations under 25 percent of normal. Portions of middle and northeastern Tennessee received 0.5 to 1 inch of precipitation, but amounts were insufficient to offset ongoing 30- to 90-day precipitation deficits. Degradations occurred across the southern Plains into the Lower Mississippi Valley as short- to mid-term precipitation deficits continue to grow across Louisiana, Arkansas and portions of Texas and Oklahoma, with many areas 2 to 6 inches below normal over the past few months. Soil moisture percentiles remain below normal across much of the region and are particularly low in central Louisiana, southern Arkansas and parts of western Oklahoma and South Texas. Streamflows in several basins continue to run below seasonal averages, with some gauges in low percentiles following weeks of limited recharge.
In Deep South Texas, long-term dryness continues to intensify. From August 14, 2025, through February 10, 2026, Rio Grande City ranks as the fifth warmest and third driest on record dating back to 1928, while McCook ranks as the second warmest and sixth driest since 1942 according to NWS and NOAA. A nearby Texas Mesonet site near Hebbronville recorded just 3.81 inches over the past 180 days, and another Mesonet site along the Starr and Jim Hogg County line recorded 11.5 inches, with only 0.33 inches falling during December and January combined. Persistent six-month precipitation deficits and continued warmth reinforced long-term hydrologic stress across the lower Rio Grande Valley…
Looking Ahead
Over the next five to seven days (Feb. 12โ17), a widespread and active precipitation pattern is forecast across much of the western and southern U.S. The heaviest totals are expected from eastern Texas into Arkansas, where widespread amounts of 3 to 5 inches are forecast, with locally higher totals possible. Additional areas of 1 to 3 inches are expected across much of the lower Mississippi Valley, central Gulf Coast, and into portions of the Southeast. Farther west, widespread precipitation is forecast across California, the Great Basin, and into the central and northern Rockies, where liquid-equivalent totals of 1 to 3 inches are expected, with locally higher amounts in favored terrain. Lighter but still meaningful precipitation is forecast across portions of the Midwest and into parts of the Mid-Atlantic and Northeast. In contrast, much of the northern Plains is expected to remain relatively dry during this period.
The Climate Prediction Centerโs 6-10 day temperature outlook (Feb. 17โ21) favors above-normal temperatures across much of the central and eastern U.S., including the Plains, Midwest, Ohio Valley and Southeast. The strongest probabilities for above-normal temperatures are centered over the central Plains and lower Mississippi Valley. In contrast, below-normal temperatures are favored across much of the West Coast and portions of the Great Basin. Alaska favors below-normal temperatures across much of the mainland, while Hawaii is favored to see above-normal temperatures.
The CPC 6-10 day precipitation outlook (Feb. 17โ21) favors above-normal precipitation across much of the western United States, including California, the Great Basin, and the northern and central Rockies. Above-normal precipitation is also favored across parts of the northern Plains and Upper Midwest. In contrast, below-normal precipitation is favored across the southern tier from southern Texas eastward across the Gulf Coast and into Florida. Much of the central United States, including portions of the Tennessee and Ohio Valleys, is favored to see near-normal precipitation during this period.

Biologist David Inouye spent part of his Tuesday afternoon harvesting Jerusalem artichokes from his garden in the 1,400-person town of Paonia in western Colorado.
โItโs been so warm and dry here that my gardenโs ready to plant,โ Inouye said. โI was actually thinking about maybe planting some spinach or peas this week.โ
Even with current snowstorms, Coloradoโs snowpack this year is, frankly, horrible. The entire state has been in a snow drought with a record-low snowpack. The signs are everywhere: Skiers see it when they hit the slopes. Water providers keep an eye on their reservoir levels and talk about summer watering restrictions. Wildland fire experts gauge fire risk this summer and push people to remove flammable brush from their properties.
Two weeks ago, Inouye skied up to the Rocky Mountain Biological Laboratory near Gothic, where he and other scientists have been conducting research for over 50 years, and saw exposed dirt patches at 9,500 feet of elevation โ areas that would normally be buried by snow. Bees, wildflowers, marmots and more could all be affected by this seasonโs thin, weak snowpack.
Snow showers in this weekโs forecast offer a dose of relief, but they wonโt be enough to get the state out of a tough, dry year. The Colorado Sun sought out experts from around the state to see whatโs going on โ and what we need to watch for looking ahead.
Coloradoโs winter has been unseasonably warm with so few snowstorms that the mountain snowpack is the lowest itโs been since 1987.
Climatologists are scouring data from high-elevation federal weather stations, called SNOTEL stations, to gauge what this yearโs water supply is going to look like. Stations were built over the years until, by 1987, there were enough to provide a comprehensive look at statewide snowpack.
As a headwaters state, snowmelt from Coloradoโs mountains runs in all directions to provide water to communities in 19 downstream states before it reaches the Pacific Ocean and Gulf of Mexico.
This year is not quite as bad as two terrible winters in recent memory: 1976-77 and 1980-81. But some smaller watersheds in the state have been dry enough to break even those records, according to state climatologists at Colorado State Universityโs Colorado Climate Center who analyzed hand-gathered measurements that date back to 1940.
What has really set this water year apart is how warm itโs been, according to the climate center. Colorado just had the third warmest November and the warmest December in over 130 years of records.
Colorado is over 60% of the way through its snow season, which means thereโs still some time to avoid a historically bad, record-breaking year statewide. But the chance of getting a normal snowpack becomes slimmer every day, said Peter Goble, assistant state climatologist at the climate center.
The winter storms this week will help, he said. But even if Colorado had a repeat of 2019 โ an above-average snow year โ from February through April, its snowpack would still be just below normal.
โWe have not yet had a year when we were running really low at this point and then just had a magical second half of the snow season and got all the way back,โ Goble said.
Visitation is down at ski resorts
The poor snow year has already taken a toll on ski resorts and local economies.
Vail Resorts last month told investors that visitation to its 37 North American ski areas was down 20% through Jan. 4 compared with the previous season. Company CEO Rob Katz pointed to โone of the worst early-season snowfalls in the Western U.S. in over 30 yearsโ โ with snowfall at the companyโs Rocky Mountain ski areas in Colorado and Utah down 60% from 30-year averages โ as the main reason behind the decline.
The companyโs Beaver Creek, Breckenridge, Crested Butte Mountain Resort, Keystone and Vail ski areas account for more than a quarter of resort visitation in Colorado, the most trafficked ski state in the country. Vail Resorts is among several resort operators across the state that are cutting hours for workers as visitation ebbs and the lack of snow limits open terrain.
Colorado Ski Country has indicated its 20 members are seeing visitation declines in the โsizable double digits.โ
Sales tax reports and end-of-season visitor counts are not due for a few months but several mountain communities are reporting lodging occupancy declines for the season around 10% as the snow-starved season limps further into February.
Meanwhile, the historic drought across the West has led to resort closures. In Oregon, Hoodoo, Mount Ashland and Mount Hood Skibowl have suspended operations as they wait for snow and Willamette Pass ski area is closed for two days midweek.
The thin snowpack left Coloradoโs backcountry slopes with low avalanche danger in the middle of the winter, and thatโs unusual, Ethan Greene, director of the Colorado Avalanche Information Center, said.
Since Nov. 1, CAIC has counted 31 people caught in avalanchesresulting in three injuries and no fatalities. That compares to 28 people caught in avalanches through mid-February in the 2024-25 season, resulting in three injuries and zero deaths. In the same span of the 2023-24 winter, CAIC tallied 47 people caught in avalanches, with three injuries and two deaths.
For winter sports enthusiasts, more dry days wonโt be a great outcome, Greene said. More storms increase avalanche danger, but they also improve riding conditions.
This weekโs winter storms bumped the danger level in northern Colorado to moderate and considerable levels Wednesday, up from a low danger rating Tuesday, based on the centerโs avalanche danger map.
โWe have a very thin and very weak snowpack,โ Greene said. โItโs not posing a lot of danger right now, but if we go into a really active weather pattern that could change pretty substantially.โ
City water also increasingly in doubt
Near-term droughts are a golden opportunity for Colorado water agencies to tap their long-standing signs declaring the need for more reservoir storage.
The water providerโs reservoirs are at 60% of capacity, which is lower than the city wants to see for this time of year, particularly with a record-low snowpack, Aurora Water spokesperson Shonnie Cline said. The region would have to get all of its normal snowfall โ plus another 50% โ over the next two months to get back to average.
The city council will soon decide whether it will declare deeper drought restrictions for this summer, she said. Restrictions arenโt out of the question for another big Front Range water provider, Denver Water, which serves 1.5 million people in Denver and surrounding suburbs.
Denver Water draws 90% of its water supply from the mountain snowpack in the Colorado River and South Platte basins. The snowpack near its water diversion tunnels and pipelines in these basins was 55% and 42% respectively as of Monday.
Northern Water, which serves community water agencies and ditches for 1.1 million people and 615,000 acres, said reservoir storage levels for its Colorado-Big Thompson Project are higher than in previous looming snowpack droughts.
That project โwas built for years just like this one โ where a low water supply threatened the ability of the farms and cities in our region to produce the economic benefits expected,โ Northern Water spokesperson Jeff Stahla said. โWhat that means is that we have enough water in storage right now to ensure crops get out of the ground and cities can produce the materials needed for this upcoming high-demand season.โ
Northern Water has also been in talks for months with members who had bought into a $2.7 billion, two-reservoir and pipeline plan to add storage along the Poudre and South Platte rivers. Some communities have signaled they will drop out because of the massive projectโs rising costs, while Northern Water has pointed to communities that stayed in because they need supply for future growth and stability.
The dozen-plus community water agencies receiving Northern Water this year, though, will have to consider drought savings measures.
โWe anticipate that communities within our boundaries will likely put in place policies to ensure we donโt waste any water and can ensure that we use the stored water for as long as possible,โ Stahla said.
On Thursday, Northern Waterโs board will hear a proposal to tap into an additional pool of water, called the administrative pool, that wasnโt used last year. The board will have to consider the possibility that this yearโs drought might last longer than one season as it considers how much to draw from reserves, Stahla said.
A deep drought from 2000 to 2002 cut into their reservoir storage and supplies, depleting it so much that it took seven years to recover, he said.
โWe recognize that we should be thinking about many variables as we look to release water for 2026,โ Stahla said.
It could get too cold for the pikas
The low snowpack could have impacts on critters in the high country.
โPikas depend on snowpack to insulate them from cold winter temperatures at high elevations, so the low snowpack could potentially make it harder for them to survive the winter,โ said Megan Mueller, a conservation biologist with nonprofit Rocky Mountain Wild.
Through the Colorado Pika Project, a partnership between the nonprofit and the Denver Zoo, community scientists collect data in Coloradoโs mountains in the summer to help scientists better understand the pika population and how it is being impacted by climate change.
Because the surveys take place in the summer, Mueller said itโs not yet clear what consequences this yearโs dry weather will have on pikas. But existing research shows pika populations have gone extinct at sites where winter snowpack was insufficient for insulating them from the extreme cold.
Volunteers seeking to help scientists better understand the impact of this yearโs snowpack on Coloradoโs pikas can sign up online to join the Pika Patrol.
Ground squirrels, marmots, chipmunks, bears and other mountain mammals might have to use more energy to stay warm in their habitats without that snowy insulation. Burning energy faster could mean some will starve or emerge from hibernation earlier, according to Inouye with the Rocky Mountain Biological Center.
And just like mammals, insects and plants struggle in warm, dry winters.
Colorado has about 1,000 species of native bees, many of which spend winter underground and depend on the snowpackโs insulation.
Inouye has been watching how wildflowers, like aspen sunflowers and larkspurs, bloom in different conditions since 1973. Flowers start to bloom as soon as snow melts. With a thin snowpack, that melt could happen in mid-April, especially on sunnier, south-facing slopes. Wildflowers will start to bloom early and could be stunted by hard freezes that can typically appear through early June.
An early, sparse bloom affects pollen resources, which are key for bumblebees and migrating hummingbirds as they nurture larval bees or lay eggs, Inouye said.
โItโll certainly be a very early season for the blooming of the wildflowers,โ he added. โThatโs typically associated with lower numbers of flowers.โ
Fire managers fear early start to fire season, severe wildfires
This yearโs low snowpack has wildfire managers fearing an early start to fire season and severe fires as the temperatures rise, especially along the Front Range.
โWe havenโt seen anything quite like this in 30 years,โ the state fire divisionโs planning section Chief Rocco Snart said.
The lack of snowpack this year reminds Snart of the conditions that led to the โhorrific fire seasonsโ in 2000, 2002 and 2012.
โThey were in the same realm as where weโre at today. But now weโre worse than those,โ he said.
n those years, more than a dozen notable wildfires ignited amid extremely dry conditions. Hundreds of thousands of acres burned across the state and hundreds of homes were destroyed. In 2000, two human-caused fires destroyed 80 homes on the Front Range, while another fire sparked by lightning scorched 23,607 in Mesa Verde National Park, according to the National Weather Service.
In 2002, six massive fires sparked across the state, including the arson-caused Hayman fire that charred more than 137,000 acres across five Front Range counties and became the largest wildfire in Colorado history at the time. Five firefighters died and more than 600 structures were destroyed.
Waldo Canyon Fire
And in 2012, six massive wildfires rapidly spread amid extreme drought. Among them was the Waldo Canyon fire, which scorched 18,000 acres near Colorado Springs and destroyed 346 structures. Two people died.
If Colorado doesnโt start to see more precipitation soon, Snart said he fears wildfires will begin igniting much earlier than previous years, in March or April, and be fueled by winds. Vegetation will be dry as no new growth will have sprouted by then.
Snart sees wildfire risk along the Front Range as โespecially problematicโ because it picks up down-sloping winds from the mountains which are a โprime driverโ of early season fires.
Fire risk is also very high along parched lower elevations of the Western Slope, he said.
Residents can take advantage of the warmer weather and start mitigating areas around their homes and being cautious of any activity that could cause sparks, especially on windy days, Snart said.
Jared Gardner apologizes for the interrupting beeps from his tractorโs GPS system as he makes his way across the familyโs 3,500-acre farm near Rocky Ford. But he explains that itโs a different technology โ the data on his smartphone โ that grabs his attention multiple times each day as he considers the fate of the fields where he cultivates alfalfa, corn, sorghum and a mix of watermelons, cantaloupes and pumpkins.
Snowpack numbers, harvested from SNOTEL sites, influence planting in this agricultural corridor of the Lower Arkansas Valley. Snowpack determines runoff, which determines the flows of the Arkansas River, which determines what to grow and what to avoid.
When Gardner Farms plots out a two-year plan for crop rotation, it begins with a best-case scenario of conditions, untethered to limitations of drought. Closer to planting time, lower water estimates may steer operations to a Plan B, which might mean trimming back acreage for the thirstiest crops.
โMy brother and I are probably on Plan C or D already, looking at this snowpack,โ Gardner said. โIt would take a small miracle to turn this thing around in a fashion that youโd say I have an ample supply of water. So for us, the first thing I do is pull corn back, to grow something with the yields that you need to break even in this marketplace. Thereโs not a lot of wiggle room for failure.โ
A little more than an hour east on U.S. 50 near Lamar, Dale Mauch pays less attention to the snowpack numbers than the long-range weather forecasts, which he checks two or three times a day to gauge the fortunes of his 4,000 acres of hay, corn, wheat, oats and sorghum.
โThe transition is supposed to be coming, but it may not be here till May, which could be too late for this yearโs snowpack,โ Mauch said, noting that his planting plans remain uncertain amid some forecasts that predict up to four feet of snow over the next few weeks.
Colorado Drought Monitor February 10, 2026.
โThe silver lining for us down here by Lamar is weโve had some storms with pretty good moisture,โ he added. โSo as far as being dry, weโre not in that bad of shape. Weโre in better shape than the mountains right now.โ
Overall, experts say the outlook for farmers โ and ranchers, whose livestock rely on the same snowpack โ leans away from optimism.
โItโs pretty grim,โ said Kristen Boysen, managing director of the state Agriculture Departmentโs Office of Drought and Climate Resilience. โProducers are definitely bracing for the worst, but I donโt think anyone has changed their plans yet.โ
Final decisions on what crops to plant, the size of cattle herds based on available water, and where to find extra grazing pastures or hay supplies all need to be made at most farms and ranches within a month, Boysen said. Even if agriculture sees snow over the mountains in the next few weeks, she added, the growing season may already be compromised.
โAcross the state, weโve seen so little moisture, so the soil is really dry,โ Boysen said. โSo any runoff we get from the mountains will just get sucked up so fast by the soil. And I think peak runoff will be very early. I think theyโre crossing their fingers that it rains on their farm.โ
Back in Rocky Ford, Gardner remains hopeful that a cold front forecast for the coming days might generate moisture to fulfill a farmerโs innate optimism. But even a foot or so of snow in the mountains probably wonโt translate, in the long run, to much relief.
โUnless we just get an epic blizzard in the mountains, that sort of snow is kind of a Band-Aid for a bullet hole right now,โ Gardner said. โAnd Colorado knows that. I think everyone in Colorado understands what a lack of snowpack means to the state, whether you ski on it, or irrigate with it, or just want to drink it.โ

Synopsis: A transition from La Niรฑa to ENSO-neutral is expected in February-April 2026(60% chance), with ENSO-neutral likely persisting through the Northern Hemispheresummer (56% chance in June-August 2026).
La Niรฑa continued in January 2026, with below-average sea surface temperatures (SSTs) observed in the east-central equatorial Pacific Ocean. The latest weekly Niรฑo-3.4 index value was -0.9ยฐC, with the westernmost (Niรฑo-4) and easternmost (Niรฑo-1+2) indices at -0.4ยฐC and 0.0ยฐC, respectively. The equatorial subsurface temperature index (average from 180ยฐ-100ยฐW) significantly increased, reflecting the strengthening and expansion of above-average subsurface temperatures across the Pacific Ocean. Atmospheric anomalies weakened due to subseasonal variability, but still reflected aspects of La Niรฑa. Low-level westerly wind anomalies were present over the western equatorial Pacific, and upper-level westerly wind anomalies continued across the east-central equatorial Pacific. Suppressed convection was weakly evident near the Date Line and over the equatorial Maritime Continent, with enhanced convection located off the equator. The traditional and equatorial Southern Oscillation indices were positive. Collectively, the coupled ocean-atmosphere system remained consistent with La Niรฑa.
The North American Multi-Model Ensemble (NMME) average, including the NCEP CFSv2, favor the onset of ENSO-neutral in February-April 2026. The team consensus also reflects this outcome, with ENSO-neutral persisting through the Northern Hemisphere summer 2026. For the late summer and beyond, there is a 50-60% chance of El Niรฑo forming, though model uncertainty remains considerable and forecasts made this time of year tend to have lower accuracy. In summary, a transition from La Niรฑa to ENSO-neutral is expected in February-April 2026 (60% chance), with ENSO-neutral likely persisting through the Northern Hemisphere summer (56% chance in June-August 2026.
Mountain snowmelt is the lifeblood of the Great Salt Lake, providing the vast majority of its fresh water. On average the mountains around the lake contribute approximately 1.9 to 2.1 million acre-feet of surface runoff annually.1 However on February first of this year – with Utah’s snowpack in near record-poor condition, Utah’s Natural Resources Conservation Service released a report that forecast a reduction in snowmelt that ranges from 21% to 77% of average.2
This (potentially) dramatic drop in snowmelt forces our attention to the Great Salt Lake’s other major source of water, the Bear River, and there the news is equally alarming. The Bear River in Utah faces a variety of environmental threats primarily from human activities like agriculture, water management, and development. These impact water quality, habitats, and flows into the Great Salt Lake. The following list of challenges the river faces are ranked in order of prevalence and severity, from reports like wetland studies and conservation plans.3
Clusters of microbialites, potentially thousands of years old, are endangered by The Great Salt Lake’s declining water levels and the water’s rising salinity. Video by Robert Marcos.
Water Diversions: Proposed and existing diversions, such as the Bear River Development project, threaten to reduce flows by up to 220,000 acre-feet annually, lowering Great Salt Lake levels by 8.5-14 inches and exposing lakebed dust with toxins like arsenic. This exacerbates drought effects and harms migratory birds reliant on Bear River Bay wetlands.4
Agricultural Runoff: Runoff from intensive farming affects 83% of wetlands, delivering excess nutrients, sediments, and pollutants that cause eutrophication, algal blooms, and oxygen depletion. The Bear River is impaired throughout the study area due to these inputs, worsened by upstream sources in Utah, Idaho, and Wyoming.5
Hydrologic Alteration: Dams, irrigation, and impoundments alter flow timing and flooding, impacting nearly all wetlands and degrading riparian habitats. Reservoirs like Cutler divert spring runoff, leading to inconsistent river flows and wetland desiccation.6
Invasive Species: Non-native plants like Phragmites australis cover 11% of wetlands, outcompeting natives and reducing biodiversity, especially in disturbed mudflats. Agricultural species such as foxtail and clover invade via forage planting.7
Sediment and Pollution: Erosion from tributaries and livestock causes siltation, while point sources (69% of wetlands) and nanoparticles from boat paints add contaminants. Legacy issues like high alkalinity and industrial wastes persist.8

Floyd Dominy, the commissioner of the federal Bureau of Reclamation in the 1960s, was largely responsible for the construction of Glen Canyon Dam on the Colorado River. In 1963, when the dam was completed, he could not have foreseen the climate situation we find ourselves in today, with declining snowpack, record-high temperatures and alarmingly low water levels in Lake Powell, year after year. But he and his engineers could have, and should have, foreseen that the way they designed the dam would leave little room to maneuver should a water-supply crisis ever impact the river and its watershed.
Indeed, a state of crisis has been building on the Colorado for decades, even as the parties that claim its water argue over how to divide its rapidly diminishing flows. Lately, things have entered a new and perilous phase. Last Nov. 11 was a long-awaited deadline: Either the states involved โ California, Arizona, Nevada, Utah, New Mexico, Colorado and Wyoming โ would have to agree on a new management plan, or else the federal government would impose its own, something none of the parties would welcome. Meanwhile, the 30 tribes that also hold claims to the river have historically been and continue to be excluded from these negotiations.

That deadline came and went, and instead of acting, the government punted, this time to Feb. 14. Nobody was surprised: Unmet deadlines and empty ultimatums have been business as usual on the river for years. Decades of falling reservoir levels and clear warnings from scientists about global warming and drought have prompted much hand-wringing and some temporary conservation measures, but little in the way of permanent change in how water is used in the Colorado River Basin.

For decades, the seven Basin states have used more water than the river delivers by drawing their entitlements from surpluses banked in reservoirs during the wet 1980s and โ90s, chiefly in Lake Mead and Lake Powell. Never mind that those entitlements were based on an over-estimate of river flows in 1922, when the Colorado River Compact was established, rendering the โpaperโ water of the entitlements essentially a fiction, not to mention a source of continual conflict. That savings account has now been drained: Mead and Powell are each below 30% full, and the trend is steadily downward. Global warming has only accelerated the decline: So far this century, the riverโs flow has fallen 20% from its long-term annual averages, and scientists forecast more of the same as the climate continues to heat up.

Here the water level is above dead pool, meaning water can be released via the river outlets, but it is below minimum power pool, so water cannot yet enter the penstocks to generate electricity.

Meanwhile, the physical infrastructure that enables Colorado River water management is on the verge of its own real and potentially catastrophic crisis โ and yet Reclamation has barely acknowledged this, with the exception of an oblique reference in an unpostedย technical memorandumย from 2024. The falling reservoir levels reveal another, deeper set of problems inside Glen Canyon Dam, which holds back the Colorado and Lake Powell. The 710-foot-tall dam was designed for a Goldilocks world in which water levels would never be too high or too low, despite the well-known fact that the Colorado is by far the most variable river in North America, prone to prodigious floods and extended droughts. But the Bureau, bursting with Cold War confidence โ or hubris โ chose to downplay the threat. In the record-breaking El Niรฑo winter of 1983, the Bureau almost lost the dam to overtopping, due to both its mismanagement and its design, because the dam lacks sufficient spillway capacity for big floods. Only sheets of plywood installed across its top and cooler temperatures that slowed the melting of that yearโs snowpack saved Glen Canyon Dam.

Today, the dam is threatened not by too much water but too little. In March 2023, the water level of Lake Powell dropped to within 30 feet of the minimum required for power generation, known as โminimum power pool.โ At 3,490 feet above sea level, minimum power pool is 20 feet above the generatorsโ actual intakes, or penstocks, but the damโs eight turbines must be shut down at minimum power pool to avoid cavitation โ when air is sucked down like a whirlpool into the penstocks, forming explosive bubbles which can cause massive failure inside the dam.
Even more worrisome is what would happen next. At minimum power pool, the penstocks would have to be closed, and the only remaining way to pass water through the dam is the river outlet works, or ROWs: two intakes in the rear face of the dam leading to four 96-inch-diameter steel pipes with a combined maximum discharge capacity of 15,000 cubic feet per second. However, the ROWs, also known as bypass tubes, have a serious design flaw: They are unsafe to use for extended intervals, and start to erode when the reservoir is low.
In 2023, when the ROWs were used to conduct a high-flow release into the Grand Canyon at low-reservoir levels, there was, in fact, damaging cavitation, and the Bureau has warned that there would likely be more in the event of their extended use. In practice, safe releases downstream may only be a fraction of their claimed capacity โ and if the tubes begin to experience cavitation, flows may need to be cut off entirely. Such a scenario would compromise the damโs legal downstream delivery requirements, or, to put it bluntly, its ability to deliver enough water to the 25 million people downstream who rely on it โ as well as the billions of dollarsโ worth of agriculture involved. This means that Lake Powell โ and with it, the entire Colorado River system โ is perilously close to operational failure.
If reservoir levels drop to the ROWsโ elevation of 3,370 feet above sea level, Lake Powell would reach โdead pool,โ where water would pass through the dam only when the riverโs flow exceeded the amount of water lost to evaporation from the reservoir. No other intakes nor spillways exist below the ROWs. There is no โdrain plug.โ Yet there is more dam โ 240 feet more before the bottom of the reservoir, effectively the old riverbed. This not-insignificant impoundment โ about 1.7 million acre-feet of water โ would be trapped, stagnant and heating in the sun, prone to algal blooms and deadly anoxia. The lake would rise and fall wildly, as much as 100 feet in a season, because of the martini-glass shape of Lake Powellโs vertical cross section.

Insufficient or no flows through Glen Canyon Dam would be a disaster of unprecedented magnitude, affecting vast population centers and some of the biggest economies in the world, not to mention ecosystems that depend on the river all the way to the Gulf of California in Mexico. The Lower Basin states of California, Arizona and Nevada warned as much in a recent letter to Interior Secretary Doug Burgum, saying that Reclamationโs failure to mention the damโs plumbing problems in its current environmental impact statement for post-2026 operations is against federal law. The letter reads: โAddressing the infrastructure limitations may be the one long-term measure that would best achieve operation and management improvements to the Glen Canyon Dam.โ
To date, however, the Bureau has made no formal response.
One thing is clear: Glen Canyon Dam will need to be modified to meet its legal and operational requirements. In the process, the health of the ecosystems in Glen Canyon, above the dam, and in Grand Canyon, below it, must be considered. The best way to avoid operational failure and the economic and ecological disasters that would follow is to re-engineer the dam to allow the river to run through it or around it at river level, transporting its natural sediment load into the Grand Canyon.
Sketches by Floyd Dominy show the way he’d end the Glen Canyon Dam. From the article “Floyd Dominy built the Glen Canyon Dam, then he sketched its end on a napkin” on the Salt Lake Tribune
As it happens, Floyd Dominy himself provided us with a simple and elegant plan for how to do it. In 1997, the former commissioner sketched on a cocktail napkin how new bypass tunnels could be drilled through the soft sandstone around the dam and outfitted with waterproof valves to control the flow of water and sediment. What it prescribes is treating the patient โ the Colorado River, now on life support โ with open-heart surgery, a full bypass. Dominyโs napkin, which he signed and gave to my colleague Richard Ingebretsen, the founder of Glen Canyon Institute, is effectively a blueprint for a healthier future for the Colorado River and the people and ecosystems that depend on it.
But the window for action to avoid dead pool is dauntingly narrow and closing fast, especially given the time that would likely be required for the government to study, design and implement a fix. The Trump administrationโs gutting of federal agency expertise and capacity adds yet more urgency to the issue. Whatever may or may not get decided on Feb. 14, the feds and the basin states need to look beyond the water wars and start building a lasting, sustainable future on the Colorado River.
The seven states that take water from the Colorado River have a deadline of February 14 to come up with a river management plan that they can all agree on. And every day that passes it looks as if that deadline, not the first one they have faced, will also be missed. Valentines Day may not be one of shared love by all.
The Colorado River basin is experiencing the greatest drought and loss of flows in the past 1200 years and the various agreements crafted to deal with deepening drought, particularly the 2007 Interim Guidelines and subsequent Drought Contingency Plans, are set to expire at the end of this year.
The major sticking point is centered around how water diversions from the river will be cut, and there will be substantial cuts. Most of that burden will fall on the Lower Basin states of California, Arizona and Nevada. They are the largest users of Colorado River water. Cuts for the four Upper Basin states; Colorado, Wyoming, Utah and New Mexico are not considered in either the previous guideline and agreements nor in the recently released Draft Environmental Impact Statement (DEIS) for Post-2026 Operational Guidelines and Strategies for Lake Powell and Lake Mead by the Bureau of Reclamation. The DEIS only looks at the river below the upper reaches of Lake Powell.
This has the Lower Basin up in arms. They are demanding mandatory, verifiable and enforceable cuts by the river diversions in the Upper Basin. The Upper Basin is refusing this demand, and Arizona in particular is threatening to unleash its historical use of litigation to try and get what it wants.
Underlying this, however, is a very fundamental misunderstanding of how water diversions work between the Lower and Upper Basins. Iโm starting to think that misunderstanding is deliberate, primarily to mislead the public constituents within the Lower Basin states. [ed. emphasis mine]
Tom Buschatzke, director of Arizonaโs Department of Water Resources, has said, โWe need certainty there are reductions in upper basin usage because that is one of the two tools that we haveโฆ You canโt make it snow or rain. But you can reduce your demandโ.
But in the Upper Basin that is not as easy as it sounds.
I have read that the true skill of a good negotiator is in being able to truly understand the other sides position. There are skilled and knowledgeable negotiators in the Lower basin, but I donโt think that they truly understand the Upper Basins position. They have been accustomed, some would say addicted, to the reliable delivery of stored water for all their needs since Hoover Dam was built and began releasing stored water some 90 years ago. Only until very recently, even in the face of an unrelenting drought, have they had to deal with shortages. For the Upper Basin shortage is an annual reality.
The Lower Basin takes water from the Colorado River mainly through a small handful of very large diversions such as the All American Canal, which provides water for Imperial and Coachella Valley agriculture, the Central Arizona Project (CAP) providing water for Pheonix, Tucson, Tribes, and Arizona agriculture and the California Aqueduct, which provides water for Los Angeles, San Diego and most Southern California cities. While distribution from these few large diversions to individual contract uses may be complicated by drought, reducing the intake at their diversion points isnโt.
That situation is very different in the Upper Basin. In Colorado, Wyoming and New Mexico there are many thousands of small diversions taking water from the Colorado River, the Green River and their myriad headwater tributaries. There are a few large diversions in the Upper Basin, primarily for water taken out of the basin to Coloradoโs East Slope cities and farms and to Utahโs Wasatch Front, but these diversions are still quite small compared to those in the Lower Basin.
The largest reservoirs in the Upper Basin are those built through the Colorado River Storage Act (CRSP, 1956), such as Flaming Gorge, Blue Mesa and Navajo. These reservoirs were not built to supply Upper Basin water needs, but to provide a โbank accountโ for Colorado River Compact compliance. In other words, for the benefit of the Lower Basin. Releases from these reservoirs are contemplated in the Post-2026 DEIS to maintain water elevations in Lake Powell that protect vital dam infrastructure and hydropower generation.
Lake Powell is also an Upper Basin reservoir in the CRSP Act of 1956. It was built entirely for Compact compliance and water deliveries to the Lower Basin. It has no water supply benefit to the Upper Basin other than as a Compact savings account.
A major wrinkle in any mandatory curtailments in Upper Basin diversions is simply in administrative logistics. It would be a complete nightmare for water administration and the State water engineers offices. And in Colorado it would be in the Water Courts as well.
A little legal background is needed here as well.
See Article 6.
All of the Colorado Basin states have Prior Appropriation as the bedrock doctrine for their water laws. California has a bit of a mix with Riparian law, but as far as the Colorado River diversions are concerned prior appropriation rules. Prior appropriation is the doctrine of โfirst in time, first in rightโ to divert the available water. Colorado was the first to codify prior appropriation in its state constitution, in 1876. Article 16, Section 6:
“The right to divert the unappropriated waters of any natural stream to beneficial usesย shall never be denied. Priority of appropriation shall give the better right as between those using the water for the same purpose; but when the waters of any natural stream are not sufficient for the service of all those desiring the use of the same, those using the water for domestic purposes shall have the preference over those claiming for any other purpose, and those using the water for agricultural purposes shall have preference over those using the same for manufacturing purposes.“
In Colorado you donโt actually need a court decreed right to divert water to a beneficial use. Just a shovel and a ditch. However, you are still subject to prior appropriation and can be the first cut off if a call is placed on the stream. There are a lot of such small diversions without an adjudicated right. I used to water my lawn in Eagle that way.
The Colorado River Compact of 1922 was created to avoid prior appropriation between the states. The US Supreme Court had decided that when there is a dispute over water between States that held prior appropriation as their foundational water law, seniority applies across state lines. Southern California was starting to grow at a much more rapid pace than the other states, greatly alarming the headwater, Upper Basin states. The Compact was crafted so that water from the river could be allocated โequitablyโ, allowing each state to grow and develop its water at its own pace. The Compact became the foundation of what is now known as the Law of the River. Laws based on prior appropriation still govern water use and administration within each State.
Arizona and California began arguing and litigating almost immediately, with Arizona usually on the losing end. That changed in 1963 when the US Supreme Court handed down a decision that once and for all set the water allocations for the Lower Basin, based on the allocations created in the 1928 Boulder Canyon Project Act, which finally ratified the Compact and paved the way for Hoover Dam, Lake Mead and the All American Canal.
Then the seniority picture between states changed with the passage of the 1968 Colorado River Projects Act that authorized construction of Arizonaโs long fought for dream of the Central Arizona Project. To get passage, Arizona had to subordinate its water rights to California, making it the junior and first to take cuts in times of drought.

None of that extended into the Upper Basin, where the States had been getting along just fine, mostly, since the Compact was signed. These four states drafted their own Upper Colorado River Basin Compact in 1948, mainly so they could get more money from the Federal Government to build water storage and delivery projects. They did something novel, allocating each states share by a percentage of the rivers flow, not by set volumes of water as the 1922 Compact had done.

Everything was fine so long as the major reservoirs of Lakes Mead and Powell were full. That has changed considerably since the onset of the current mega, or Millennial drought began in 2000. The two reservoirs have dropped to very low levels, levels never anticipated or planned for.
Here is the crux of the matter. The Lower Basin is demanding mandatory cuts from Upper Basin uses so that more water can flow downstream for their use. The 1922 Compact says clearly that the Upper Basin states โwill not cause the river flow at Lee Ferry to be depleted below and aggregate of 75,000,000 acre feet for any period of ten consecutive yearsโฆโ. The Lower Basin states argue that this constitutes an โobligationโ to deliver that much water to them. The Upper Basin states say no, there is no delivery obligation. It is a non-depletion requirement, that through diversions and actual consumption the states canโt let those flows drop below 75 million acre feet (maf) in a ten year running average.
That has never been a problem, until now. The 1922 Compact and its non-depletion requirement is a priority right in itself. Any water right in the Upper Basin that was adjudicated, perfected by actual use and consumption, after 1922 is subject to curtailment for fulfilling the non-depletion requirement. Any and all rights perfected prior to November 1922 are exempt.
So far, as of 2026, the required flows over a ten year running average have not yet hit that non-depletion trigger of 75 maf running average over ten years. Not yet, but it could be getting close.
The Upper Basin states live by a โrun of the riverโ system as there are no large storage units dedicated to their use as the Lower Basin has with Powell and Mead. There are many small reservoirs used for a single irrigation season, filled with the spring runoff and then empty by the end of the growing season. But they also are subject to how much water comes in the spring and downstream senior calls.
Every year, especially since this mega drought and increased aridification began, Upper Basin irrigators are curtailed each summer as the streams shrink and the small reservoirs are drained. Some years this curtailment includes water rights that are senior to the Compact as well.
The Upper basin, in short, is forced to live within its means, with what it has and no more than Mother Nature provides with the winter snowpack. As Tom Buschatzke said, โYou canโt make it snow or rain. But you can reduce your demandโ. The Upper Basin does exactly that every year, especially in years like this with a record low snowpack.
The mandatory, verifiable and enforceable cuts demanded by the Lower Basin would be more than difficult to achieve. And again, it would be an administrative and legal nightmare for those assigned the task on the thousands of relatively small, individual diversions that make up the Upper Basinโs water use from the Colorado River. There are those larger trans-basin diversions to the Colorado East Slope and cities, but even if they took substantial cuts, it would still be a pretty small amount of water. No where near the amounts that the Lower Basin has become accustomed to.
Right now the Upper Basin uses roughly half their Compact allocation, roughly around 4 maf a year, while the Lower Basin has historically used more than their full Compact allocation. To their credit, the Lower Basin has made substantial cuts, some voluntary and some enforced by agreements and obligations. California was forced to cut their water use by 800,000 acre-feet with the 2007 Interim Guidelines, back to their actual decreed limit, a cut some claim as an example of how much โsacrificeโ they have made. They and Arizona have made additional cuts as well, now taking around 6 maf, from a historic high near 10 maf per year.
I agree that the Upper basin needs to work harder at conservation, and they have been trying hard over the last few years. They havenโt been hording water or ignoring the needs of the Lower Basin or those spelled out in the Compact and subsequent agreements as some in the Lower Basin claim. But โmandatoryโ cuts beyond those already happening each and every summer will require significant changes with state water law and administration. In Coloradoโs case it could well require a change to Article 16, Section Six, of the stateโs constitution which has held unaltered since 1876.
We live now in a very different world from the 1800โs and 1922 when the Compact was drafted, using highly optimistic flow calculations that they already knew were wrong. But the men who drafted it were boosters, as were their fathers, seeing the West as they wanted to, not as it really was. Americaโs westward expansion has always been driven by dreams of abundance, and for a while the river was able to provide that through massive engineering, a still small but growing population and some pretty wet years. Many still hold on to that misguided dream of abundance in an increasingly arid region.
That has all evaporated. All water users in the West, especially the Colorado River basin, expect certainty and reliability, as Tom Buschatzke declared. Weโve built an entire system, and an entire economy based on those principals. Certainty and reliability are now fading rapidly in the rear view mirror, if we dare to look. Many wonโt. The Colorado River has made the desert bloom and let us build great cities. But its dwindling supply is placing all that in jeopardy. We need to adapt. The only certain and reliable future is one with less water, greater aridity and warmer and much drier climate.
Maybe our great civilization built on a desert river will go the way of the Hohokam who filled the valley Pheonix now inhabits with irrigation canals and a thriving population. Maybe. We can change that scenario if we adapt to the new reality. That will be both hard and painful. Parochial self-interest must be balanced with regional ties and interests, and that is never easy. Nor is it politically palatable. The Lower Basin is railing against the Upper Basinโs refusal to provide water it just doesnโt have. The Upper Basin is living within its means while honoring its commitments to the Compact as best it can.
The Bureau of Reclamation in its DEIS for Post-2026 river management introduced a new concept, at least new for Colorado River management. Decision making under Deep Uncertainty, or DMDU. Many, seemingly, arenโt familiar with that concept. Even the Bureauโs recommendations may not go far enough with that concept. They donโt seriously engage the reality that both Powell and Mead are headed for deadpool, meaning that the only water available from either reservoir will be what flows in. There will be no storage to rely on. None. That will have far more devastating impacts than what any of the alternatives contemplate. [ed. emphasis mine]
But when the well runs dry there isnโt much we can do. A few years ago the concept of stationarity in climate norms, basing predictions within the parameters of historical extremes, was declared dead. The ideas of certainty and reliability are now headed for the same graveyard.

February 11, 2026
January Highlights:
The global surface temperature was the fifth-warmest January on recordโthe smallest temperature departure since 2023.
Snow cover extent was below average for North America and near average for Eurasia.
Sea ice extent was near record low for the Arctic and below average for Antarctica.
Global tropical cyclone activity was above normal with 11 named storms.
Map of global notable weather and climate anomalies and events in January 2026.
Temperature
January 2025 ranked as the fifth-warmest January in NOAAโs 177-year record, with a global surface temperature 2.02ยฐF (1.12ยฐC) higher than the 20th-century baseline. All 10 of the warmest Januarys on record have occurred since 2007, with the most recent five years (2022โ26) among the top 10.
Land and Ocean Temperature Percentiles for January 2026. Red indicates warmer than average and blue indicates colder than average.
In January 2026, unusually high temperatures prevailed across much of the Earthโs surface. The most notable high temperature departures were observed across the Arctic, Greenland, the western U.S., Canada, Africa, southern and eastern Asia and parts of Australia, where temperature departures were at least 3.6ยฐF (2.0ยฐC) above average. Several regions across the globe experienced their warmest January on record, including parts of Greenland, Africa, Asia, the Atlantic and parts of the Pacific and Southern Oceans. Notably, Africa experienced its warmest January on record, while North America, South America and Oceania had a top 10 warm January.
In contrast, notable below-average temperatures were observed in Alaska, the eastern U.S., Europe, northern Asia and across parts of Antarctica and the central and eastern tropical Pacific Ocean. However, no land or ocean areas experienced record-cold January temperatures.
Snow Cover
In January 2026, snow cover extent across North America and Greenland was 150,000 square miles below average, tying with 2002 for the 12th-smallest January extent on record. Meanwhile, Eurasia saw near-average coverage at 11.48 million square miles. Overall, Northern Hemisphere snow cover for January was slightly below average at 18.12 million square miles.
Regionally, snow deficits were most pronounced across the western half of the contiguous U.S. and central Asia extending into China. In contrast, above-average snow cover was observed in the south-central U.S. extending towards the Northeast, central and eastern Europe, Japan and parts of northern and northeastern China.
Sea Ice
Global sea ice extent was the fifth smallest for January in the historical record at 550,000 square miles below the 1991โ2020 average. The Arctic sea ice extent was below average by 340,000 square miles, tying with 2025 as the second-smallest January extent in the 48-year record. The Antarctic sea ice extent for January was the 13th smallest at 210,000 square miles below average.
Map of the Antarctic (left) and the Arctic (right) sea ice extent in January 2026.
Tropical Cyclones
Global tropical cyclone activity in January was above normal, producing 11 named storms. Four of these reached tropical cyclone strength, and two intensified into major tropical cyclones. Most of the activity occurred in the Southern Hemisphere (South Indian, Australian and Southwest Pacific basins), with one named storm in the West Pacific. No storms formed in the North Atlantic, East Pacific or North Indian basins, which is typical during January.
Notably, Tropical Cyclone Fytia, in the Southern Indian basin, made landfall in northern Madagascar at the end of the month as a strong cyclone, bringing heavy rainfall and widespread flooding. The storm caused at least 12 deaths, displaced thousands and damaged or destroyed thousands of homes.
More than 8,500 daily heat records have been tied or broken in the West this winter. "I have not seen a winter like this," said NSIDC director Mark Serreze, who has been in Colorado almost 40 years. "This pattern that we're in is so darned persistent." https://t.co/nn3WylQ9uL
The Gold King Mine spill happened on August 5, 2015, when EPA contractors accidentally released approximately 3 million gallons of contaminated wastewater into Cement Creek – a tributary of the Animas River in Colorado. The plume, containing heavy metals, flowed into the Animas and San Juan rivers. 1 The USGS – in cooperation with the EPA, gathered streamgage data in order to confirm the origin of the stream flow spike at Cement Creek and the volume of the spike estimated at three million gallons. USGS also took water and sediment samples and provided both current and historical water quality data to EPA.2
Four months later during her address to a House Committee on Natural Resources, the Secretary of the Interior Sally Jewell said, “As is so often the case, it is unfortunate that an incident like this has to happen to highlight an issue that land managers in both the state and federal governments have been grappling with for years โ that addressing abandoned mine lands is a nationwide problem, and mitigating toxic substances released from many of them is a significant undertaking. Abandoned mine lands are located on private, state, federal, and tribal lands. There aretens of thousands of abandoned hardrock sites on federal lands alone. Many of these abandoned mine land sites were mined prior to the implementation of federal surface management environmental laws that require reclamation and remediation to take place. For those mine sites where no viable potentially responsible party can be determined, the federal government, and ultimately the taxpayer, often bears the burden of addressing these threats to public safety, human health, the environment, and wildlife, rather than the entities that developed and profited from the operations.”3
In 2018 the U.S. Geological Survey, the Utah Department of Environmental Quality, U.S. Bureau of Reclamation, and National Park Service, initiated the Lake Powell Coring Project.4 Its purpose was to retrieve and analyze hydraulic piston cores from Lake Powell sedimentsโprimarily targeting the San Juan River deltaโto reconstruct the history of sediment and contaminant deposition, including assessing whether material from the 2015 Gold King Mine spill had been sequestered there. Cores taken from 40 holes penetrated up to the pre-Glen Canyon Dam surface to evaluate metal concentrations, distribution, and bioavailability for water quality impacts.5
Preliminary results shared by USGS scientists in late 2021 shared significant findings: while the 2015 Gold King Mine spill caused detectable spikes in lead and zinc, much larger and “more concerning” spikes wereidentified from mining waste disasters that occurred in the 1970s. The following contaminants were found in core samples:6
Lead: Found in significant spikes, particularly in deeper sediment layers corresponding to mid-20th-century mining disasters.
Zinc: Often found in conjunction with lead; used as a primary indicator of mine waste runoff.
Arsenic: A major concern in the San Juan River delta, often naturally occurring but concentrated by mining processes.
Cadmium: A toxic metal frequently associated with zinc mining that was identified in the core samples.
Copper: Present in the sediment, reflecting the region’s extensive copper mining history.
Mercury: Studied due to its ability to bioaccumulate in the food chain (fish), though much of the mercury in the system is attributed to atmospheric deposition and older mining practices.
Now as Lake Powell’s water levels continue to recede amid prolonged drought and heavy upstream water use, vast expanses of toxic sedimentsโladen with heavy metals like arsenic, cadmium, copper, mercury, lead, selenium, and zinc from historical mining discharges including the 2015 Gold King spillโare increasingly exposed. This drying creates a heightened risk of human exposure through direct contact during boating, fishing, or shoreline recreation, as well as inhalation of windblown dust carrying bioavailable toxins, potentially leading to respiratory issues, skin irritation, and chronic health effects with repeated exposure. Without expanded monitoring or mitigation measures, these once-submerged hazards now pose an urgent public safety threat to the millions of annual visitors in this popular Southwestern reservoir. 7
Denver Water depends on mountain snowpack for 90% of its water supply, which serves 1.5 million people in Denver and surrounding suburbs.
Snowpack as of Feb. 9, 2026, was near record lows: The Colorado River Basin within Denver Waterโs collection system was at 55% of normal. The South Platte River Basin within Denver Waterโs collection area was 42% of normal. In Denver Waterโs decades of records for its watershed collection areas, as of Feb. 9, the Colorado River snowpack ranked among the worst, and the South Platte River snowpack ranked the worst.
No matter what, Denver Waterโs annual summer watering rules will always be in place during the irrigation season. And, it is possible that we will need to implement additional drought response measures this year. Denver Waterโs response to drought conditions uses a tiered approach, including the potential for additional watering restrictions, in order to preserve water supplies. Denver Water will move closer to developing recommendations for its Board of Water Commissioners on a potential drought response over the next couple of months.
Since 2000, Denver Waterโs response to dry conditions in previous years included issuing a Drought Watch (voluntary restrictions) in 2002, 2003, 2004, 2012 and 2013. In some of those years (2002, 2003, 2004, 2013), Denver Water levied additional drought restrictions as part of declaring a Stage 1 level response, which required mandatory reductions in outdoor water use.
Denver Water snowpack update for Feb. 9, 2026
Conditions remain highly concerning. Poor snowfall combined with warm temperatures have left us roughly 4 feet of snow short of where weโd prefer to be in the Denver Water collection area.ย
Reservoir storage conditions are below average, but in reasonably good shape: 81% full versus an average of 85% full for this time. Those levels are also artificially affected by the need to keep Gross Reservoir low duringย construction to raise the dam, a project designed to increase the storage capacity of the reservoir.ย
Denver Water has been here several times over roughly 50 years of reliable records. On the positive side, we have experienced years that started dry and conditions dramatically improved in March, April and May. This year, however, we are running out of time to build a healthy winter base.
No matter what, Denver Waterโsย annual summer watering rulesย will always be in place during the irrigation season.ย Additional drought restrictions, voluntary or mandatory, will depend in part on how the rest of the snow season shapes up and will be aimed at preserving water supplies in case this unusually dry stretch deepens into a multiyear drought. ย
Comment from Nathan Elder, Denver Waterโs manager of water supply:ย
โWe are running out of winter. Conditions are highly concerning, and as we continue to hope for relief in the spring months, we also are preparing recommendations for our drought response. We encourage customers to think about conservation even now, with smart indoor use and potential changes in landscapes that would reduce outdoor use in the irrigation season.
“Water is a precious resource that supports our way of life across Colorado, from the mountains to the ski resorts to our communities on both sides of the Continental Divide. We all have a role to play in using water responsibly.ย
“If youโve been up skiing, youโve likely seen the low snowpack firsthand, and โ if conditions donโt improve โ when that snow melts, it wonโt be enough to completely fill our reservoirs this spring and summer.โ

Warm and dry conditions during January drove Colorado snowpack to record low levels statewide. Late month snowfall was insufficient to change overall conditions, increasing the likelihood of below normal peak SWE and reduced spring runoff across most river basins.
February 10th, 2026 โ Warm and dry conditions persisted across Colorado during most of January, which has led to record low snowpack for much of the state. Every major river basin across Colorado received below normal precipitation in January, ranging from 58 percent of median in the Upper Rio Grande river basin to 76 percent of median in the Arkansas river basin. Although there were a series of storm systems during the first and last week of January which delivered snowfall across the state, this was not enough to improve overall conditions. Based on the 1991-2020 median, current statewide snow water equivalent (SWE) is 55 percent of normal, and ranges from 48 percent of normal in the Arkansas river basin to 64 percent of normal in the Laramie-and-North Platte river basin. Since January 13th, snowpack across Colorado has been at record low levels when compared to the 30-year normals, and with only a couple more months left in the typical snow accumulation season, it looks less likely that we will receive enough snowfall by April 1st to achieve normal peak SWE. It would take consistent, record-breaking snowfall for the rest of the season to reach normal peak SWE, and with the long-term outlooks, that is looking highly unlikely. Based on projection plots, even if the state receives average snowfall (50% projection) for the rest of the season, we would end up around 70 percent of median peak SWE (figure 1).

Current statewide reservoir storage is 86 percent of median, slightly lower than this same time last year which was 94 percent of median. Itโs certainly not ideal to have low reservoir storage during these dry years. With basins below normal reservoir levels will likely face more severe water shortages this upcoming runoff season. All major river basins currently have below normal reservoir storage, except the Upper Rio Grande, South Platte, and Arkansas river basins which are at 120 percent, 102 percent and 100 percent of normal. February 1, 2026 streamflow forecasts at the 50 percent exceedance probability show similar spatial trends as snowpack and precipitation. Current streamflow forecasts are predicting below normal streamflow across the entire state. They range from 28 percent of normal for Sangre de Cristo Creek to 91 percent of normal for the Big Thompson River at Canyon Mouth. Notably, the combined Laramie-North Platte and Colorado Headwaters river basins have the lowest streamflow forecasts in the state at 50 percent and 58 percent of normal. Overall, the record warm and dry conditions that have persisted for much of the 2026 water year have been detrimental for Coloradoโs water supply outlook. All current indications are pointing to well-below normal streamflow across the state.

if the Colorado snowpack numbers from SNOTEL stations (52% of median) aren't low enough for you, they get even worse when looking at data across all elevations. Using the University of Arizona's SWE dataset, we're now below one-third of the usual snowpack (32.5%) as of February 9. #cowx
As evaporation rates increase and inflow from the Colorado River falls, Lake Meadโs water volume will shrink but the total mass of dissolved minerals will remain relatively stable. This creates a concentration effect where minerals like calcium, magnesium, and salts, become more densely packed in the remaining water. Without sufficient fresh inflow to dilute these minerals, the water becomes increasingly “hard,” reaching salinity levels that pose significant challenges for regional water management.1
This increasingly hard water is a silent but growing threat to household appliances owned by residents of Las Vegas, because when hard water is heated or left to evaporate, minerals like calcium and magnesium precipitate out of the liquid, forming a rock-hard crust known as limescale. This buildup acts as an insulator in water heaters, forcing them to work harder to heat water, and clogs the delicate internal components of dishwashers and washing machines. Over time, these deposits restrict water flow and corrode seals, leading to premature mechanical failure and leaks.2
The financial burden of these mineral-heavy waters translates to shorter lifecycles for major appliances and higher utility bills. Residents may find themselves replacing water heaters every 8 years instead of the typical 12 to 15, and the efficiency loss from scale buildup can increase energy costs for water heating by as much as 25%. Between more frequent appliance replacements, the cost of professional plumbing repairs, and the potential need for expensive water softening systems, the long-term economic impact on a single household can reach thousands of dollars.3
While drinking water with elevated TDS is generally considered safe by regulatory standards, it can have some noticeable effects. Very high concentrations of minerals like sulfates can cause a laxative effect or gastrointestinal discomfort in sensitive individuals or those unaccustomed to the water. While the body requires minerals like calcium and magnesium, excessive levels can affect the water’s smell and its taste, which may motivate residents to rely more on bottled water or on in-home filtration units like reverse-osmosis, which incrementally drives up the cost of living.4
A 2013 complaint that Texas was being deprived by New Mexico of its equitable apportionment of Rio Grande Compact water has finally been resolved and the compact decree approved by the special master in the case.
In a Fourth Interim Report dated Feb. 6, Hon. D. Brooks Smith agreed with the negotiated settlement by the states and the federal government that specifies how much compact water released by Colorado ends up with New Mexico and how much with Texas.
The proposed compact decree, which has to be accepted by the U.S. Supreme Court, employs use of the โEffective El Paso Index (โIndexโ),โ which provides a means of tracking the movement of water below Elephant Butte Reservoir for Texasโ accounting.
โMuch like the river whose water the parties have quarreled over for decades, this original action has proceeded in a meandering fashion. First articulated by Texas in its 2013 Complaint, the dispute, in some sense, began about 8,000 years ago, in ancient Mesopotamia, when the Sumerians invented the concept of irrigation and incited a run on Earthโs navigable waterways,โ Smith wrote in his report to the U.S. Supreme Court.
For its part, New Mexico countered that it was โexcess water consumption in Texasโ that interfered with the compact reporting. The standoff between the two states, with Colorado as a third party, lasted until July 3, 2023, when then-Special Master Michael J. Melloy issued a Third Interim Report (โTIRโ) on the matter, which began: โTexas, New Mexico, and Colorado . . . have filed a joint motion to enter a consent decree compromising and settling โall claims among them arising from the 1938 Rio Grande Compact.โโ
The proposed 2023 compact decree was filed with the U.S. Supreme Court, which rejected it at the request of the federal government, and appointed a new special master in Smith. He brought the states and federal government back together for another round of talks, and in June of 2025 visited the lower Rio Grande to talk to farmers and to familiarize himself with the features of the basin.
โI am grateful to the parties, the amici, and all of counsel for their cooperative efforts in organizing and carrying out what was a highly informative and comprehensive real-time view of both the waters of the Lower Rio Grande and the Project,โ Smith wrote in his report.
The Effective El Paso Index (โIndexโ), which is a feature of the proposed compact decree, measures compliance based on the amount of water that actually passes through the El Paso Gage.
โI am pleased that the Special Master has recommended the U.S. Supreme Court accept the partiesโ proposed settlement of the Rio Grande Compact litigation. The settlement is the result of collaboration between Texas, New Mexico, Colorado, and the United States; it includes entry of a proposed Compact Decree and dismissal of the United Statesโ claims,โ said Colorado Attorney General Phil Weiser. โI appreciate the Special Masterโs thoughtful engagement in the matter and his recommendation supporting this collaborative result. His recommendation gets even closer to the finish line.โ
The last step will be a decision from the Supreme Court, which Weiser said he hopes to receive by June.

Coloradoโs mountain snowpack is in bad shape this year. Itโs been extremely warm, and snowstorms have been few and far between. Based on data from the SNOTEL network, the amount of water stored in the snow is the lowest at this point in the winter since at least 1987. Sometimes when one part of the state is lacking for snow, another region is doing ok, but not this year. Essentially all of Colorado is in aย snow drought.

Snow droughts have beenย getting more commonย in Colorado in the 21st century. But those who have been around Colorado longer than I have may also remember two other terrible winters for snow: 1976-77 and 1980-81. In fact, some photos sit on my desk from former state climatologist Nolan Doesken from tours through the mountains in those years. At that time, snowmaking was uncommon at the ski resorts, and there were serious concerns about whether the ski industry would survive through those two historic snow droughts. (This storyย from 2012 by Jason Blevins, then at the Denver Post, now at the Colorado Sun, has some relevant background.) Weโve been fielding quite a few questions about how the snowpack this winter compares to those brutal years, so letโs take a closer look.

First, a bit about snow measurements
Because of the importance of mountain snow to water supplies, the federal government (specifically, the Department of Agriculture) has for decades collected snowpack data across the western US. The USDA snow survey was established in the 1930s, with routine โsnow courseโ measurements in the winter and spring. These are manual measurements of the snow depth, snow water equivalent, and so on. (Hereโs some archival footage of snow surveying. I believe that smoking a pipe while taking the measurements is discouraged these days.)
Photos of USDA staff taking snow measurements. From the Colorado Snow Survey website.

Measuring snow this way takes a lot of time and effort, however. So the 2nd pillar of the USDAโs snow survey program, the โSnow Telemetryโ or SNOTEL network, was established starting in the 1960s. These are automated stations that use a โsnow pillowโ to measure the weight of the snow, and convert that into an amount of liquid water, among other measurements. SNOTEL data allow agricultural producers, water managers, climatologists, and the public to keep tabs on the snowpack in near-real-time. The snow course measurements have the advantage of a longer period of record to compare to, but are only collected once a month from February through May; the SNOTEL data are available daily from over 100 stations but with a shorter period of record.
What do the data show for this winter?
The graph up at the top shows that in the SNOTEL era, Coloradoโs snowpack is the worst on record as of early February. However, there werenโt yet any SNOTEL stations in Colorado for the 1976-77 winter, and the network was still being built out as of 1980-81. So, if we want to compare the current snowpack to those two years, weโll have to take a look at the tried-and-true snow course measurements, which the USDA has been collecting for the first time this season over the last week or so.
When comparing the snow water equivalent on February 1st at 62 snow courses with more than 50 years of data, there are eight sites where this year (2026) is the lowest on record. They are shown with the dark brown circles on the map below. Another fourteen sites have either the 2nd or 3rd lowest snowpack on record, and many more are in the bottom 10 years historically.

We can also look at which years had the lowest SWE as of February 1. At the locations where this year isnโt the worst snowpack, the worst February conditions were generally either in 1977 or 1981 (with some dishonorable mention to 2018 in the southern mountains.)

Using data from 20 snow course sites in Colorado with consistent data back to at least 1940, we can see that this year has the lowest snow water equivalent since the two terrible years of 1977 and 1981, and lower than any of the other years in the record.

So, itโs fair to say that this year so far has the worst snowpack in Colorado in over 40 years. But in most locations itโs not quite as bad as the conditions were in 1976-77 and 1980-81.
However, obviously a lot of things have changed since the late 1970s! Nearly all ski areas now have robust snowmaking operations, which allow them to keep terrain open even when thereโs not much snow falling from the sky. On the flip side, the population of Colorado has grown immenselyโapproximately twice as many people live in the state now as did in 1980. Which means that the demand for water (and for winter recreation) is much greater, and thus the potential impacts of a snow drought are much greater as well.
What has really set this water year apart thus far is how warm itโs been. For Colorado statewide, we just had the 3rd warmest November and the warmest December in over 130 years of records. January was very warm as well. Official numbers for January will be released this week (make sure youโre signed up to get our monthly summaries), but it clearly ranked among the top 20 warmest Januarys, and early February has continued the streak of warmth. The warmest start to a water year weโve ever seen, combined with a lack of the snowstorms we typically see in winter, has brought us to the worst mid-winter mountain snowpack in decades.
We do still have about 2 months to go before the mountain snowpack typically hits its peak, which means there is still time to chip away at the deficit. Looking back at the major mid-winter snow droughts discussed above, in 1977 it remained dry in late winter and spring, and that season still holds the record for worst April 1 snowpack at many locations in Colorado. In contrast, the spring of 1981 was fairly active; at least enough to emerge above record-low territory for much of the state.
This week, the pattern will finally shift away from warm and sunny conditions to more consistent chances for snowfall. However, itโs too early to say how long the incoming pattern will stick around, and unfortunately there arenโt any blockbuster storm cycles on the horizon in the near term. An active spring would certainly be very welcome, but the odds of rebounding to near normal peak snowpack conditions are dwindling. More realistically, we are just hoping to get enough snow to avoid a historically bad year.

From email from Reclamation Western Colorado Area Office:
The Bureau of Reclamation has scheduled a decrease in the release from Navajo Dam from 350 cubic feet per second (cfs) to 300 cfs for Tuesday, February 10th, at 8:00 AM.ย
Releases are being made through the 4×4 gates while the powerplant is down for maintance.
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. ย If you have any questions, please reply to this message, call 970-385-6500, or visit Reclamationโs Navajo Dam website atย https://www.usbr.gov/uc/water/crsp/cs/nvd.html

February 2, 2026
This story is part of ongoing coverage of the Colorado River, produced by KUNC in Colorado and supported by the Walton Family Foundation. KUNC is solely responsible for its editorial coverage.
Governors and negotiators from the seven Colorado River basin states met behind closed doors for about two hours in Washington on Friday [January 30, 2026] to talk with Interior Secretary Doug Burgum about the dwindling waterwayโs future.
After they left the meeting, governors were quick to issue statements praising the gathering as โproductiveโ and โmeaningful,โ but no deal among the states was announced by Monday afternoon.
โThere isโฏstill a lot of work ahead to get to an agreement, but everyone wants an agreement, and weโll work together to create a pathway forward,โ New Mexico Governor Michelle Lujan Grisham said in a statement.
Arizona Gov. Katie Hobbs said she was โencouraged to hear Upper Basin governors express a willingness to turn water conservation programs into firm commitments of water savings.โ
Upriver in Colorado, Gov. Jared Polis said in a statement he โdefended our mighty Colorado River.โ

โI always fight to defend our water, whether itโs at the Department of Interior, Congress, or the courtroom,โ he said.
Utah Gov. Spencer Cox said he left the meeting โhopeful that weโll avoid the path of litigation.โ
โNo one wins going down that path,โ he said in a statement.
And Wyoming Gov. Mark Gordon issued perhaps the most optimistic statement of the group.
โI am wholeheartedly encouraged by our conversation and believe there is a definitive pathโ toward a deal, he said.
California Gov. Gavin Newsom missed the meeting, but his natural resources secretary, Wade Crowfoot, was in the room.
Crowfoot said in a statement afterward that he was โcautiously optimistic that an agreement is possible, and weโre working hard to make it happen.โ
Negotiators from the lower and upper basins entered the meeting at a yearslong impasse over how water restrictions should be managed during dry years.
They now have less than two weeks until a federal Feb. 14 deadline to reach an agreement.
Pressure to reach a deal is building.
Forecasts for the water supply from the Colorado River continue to grow worse as snowpack lags far behind normal across the West.
And negotiators from the basins have said there are โsticking pointsโ that remain in the negotiations in recent weeks that even marathon talks have failed to resolve.
“Some in the lower basin wanted some sort of guaranteed supply, irrespective of hydrologic conditions,โ Becky Mitchell, Coloradoโs top negotiator, told KUNC last week on the eve of the DC summit. โAnd I think asking people to guarantee something that cannot be guaranteed is a recipe that cannot get to success.โ
Californiaโs negotiator, J.B. Hamby, said during a recent speech that โcontinued back and forth between the basins havenโt really been moving the ball forward.โ
He welcomed potential federal intervention to help strike a deal.
โThe administrationsโฆhave this important role in sometimes knocking heads together, sometimes encouraging consensus, and having diplomatic discussions between the states to be able to move conversations forward,โ he said.

February 3, 2026
As part of its spring tradition, the Colorado River District will give its State of the River address to a dozen Western Slope communities starting in March. Each State of the River will provide information on river forecasts, local water projects and key challenges impacting Western Slope water users. The events will take place everywhere from the Upper Yampa, Roaring Fork and the Middle Colorado river basins down to the Lower Gunnison and Uncompahgre river basins. While each programโs agenda will vary slightly and is tailored to reflect local water priorities, key topics at all events will include:
River flow forecasts, snowpack, and drought summaries
Updates on the Colorado River system and interstate negotiations
Shoshone Water Rights Preservation Project updates
Local water projects and priorities
Each event will also include a complimentary light dinner and an opportunity for residents to ask questions of water experts. While it is free to attend, the River District requests that all attendees register in advance atย ColoradoRIverDistrict.org/2026-State-of-the-River-Meetings.

February 4, 2026
Gov. Katie Hobbs said Monday that unless Upper Basin states actually offer up some firm commitments to conserve water she won’t agree to any deal for Arizona to cut its own withdrawals from the Colorado River. And that would lead to either Interior Secretary Doug Burgum imposing his own solution on the seven states that draw water from the river โ or the situation having to be hashed out in court. Only thing is, Burgum has so far refused to do more than bring the governors of the affect states together, as he did on Friday. And Terry Goddard, president of the Central Arizona Water Conservation District, which oversees the state’s Colorado River supply, said the options put forward by the Interior Department “are not palatable to Arizona or California,” one of the two other Lower Basin states.
“All Burgum’s done is set us up for litigation,” he told Capitol Media Services. “And I think that’s sad.”
Still, [Governor Hobbs] said she thinks it doesn’t necessarily have to wind up in court, even though Arizona already has set aside $3 million for litigation.
“While we didn’t leave with a lot of specifics โ the details are to be worked out through negotiation โ I think that we came away with hearing that nobody wants to end up in litigation,” Hobbs said. “We want to find a way to get to a deal.”
But Hobbs said that means recognizing that Arizona, which already has agreed to give up 27% of the water it has been getting from the Colorado River, won’t give up a drop more unless there are firm and enforceable promises that the Upper Basin states will share in the burden.

February 4, 2026
A 54-year-old water treatment plant in Breckenridge has reached the end of its life, and preliminary cost estimates put rehabilitating it at $54 million.ย Breckenridge town staff members presented Breckenridge Town Council with plans for a series of projects to help the Gary Roberts Water Treatment plant reliably meet current demand at a Tuesday, Jan. 27, meeting.ย The Gary Roberts Water Treatment is located at the Goose Pasture Tarn. A staff memo stated the town first evaluated improvements and rehabilitation options in 2014, but they put those on hold to prioritize Goose Pasture Tarn dam repairs. The memo noted the continued aging of the plant now makes it a critical project. It included photos of the plan demonstrating pitting, corrosion and leaks in the water tanks at the plant…The project is currently proposed to be phased from 2027 to 2029. Staff members said there are no anticipated impacts to residentsโ water service. While preliminary cost estimates put the project at $54 million, the budget the town planned for was $50 million. Officials asked staff members what tools were at the townโs disposal to make the project stay within a reasonable budget.ย
The Gunnison River Basin Roundtable recently announced grants of up to $1,500 for water education through its public education, participation and outreach committee. The 2026 Water Education Grant is now accepting applications. Funds are available to anyone engaged in water education, including public and private schools, libraries, scout troops, homeschoolers, 4-H clubs and other organizations offering programming for children up to 18 years old in the Gunnison Basin. Applications are due at 5 p.m. on Feb. 23. For more information, visit gunnisonriverbasin.org/.

An unconfined aquifer that is getting โworse and worse,โ not better.
Such is the reality of the situation for the Upper Rio Grande Basin and warnings given to the San Luis Valley farming and ranching community on the final day of the 2026 Southern Rocky Mountain Ag Conference.
If youโre a praying sort, it isnโt too early in 2026 to fold your hands together toward the heavens. If not, a good wish or two would be fine as well.
The outlook is that dire. Except for the hope that a changing weather pattern from La Niรฑa to El Niรฑo at some point this year will deliver the goods and avoid even more of a collapse.
โWe do anticipate at this moment, at this date that itโs going to be a poor runoff in 2026,โ said Pat McDermott of the Colorado Division of Water Resources. It is customary for him and state division engineer Craig Cotten to provide a look back at the recent water year and a look ahead to the next spring runoff.
McDermott typically attempts a positive spin for the large audience that fills the main conference room at the Outcalt Center of the Ski Hi Complex in anticipation of the state water resources report. He did his best by pointing to a rosier outlook in the 2026 Farmerโs Almanac, the last annual edition.
It is the state, after all, that governs groundwater pumping in the San Luis Valley and has metrics Valley farmers are required to meet to stay in business. One is the recovery of the unconfined aquifer through buy-and-dry and reduced groundwater pumping strategies.
โIt just kind of gets worse and worse every year that we look at it,โ said Cotten in referencing the storage levels of the Upper Rio Grandeโs unconfined aquifer and the greater level of recovery efforts crop producers in Subdistrict 1 are facing as a result.
โUnfortunately itโs going in the wrong direction and it has been for quite some time here,โ Cotten said in referencing the latest five-year average for storage.

Warmest December on record for nine western states based on 131 years of temperature data.
Nathan Coombs and Heather Dutton, both key players in the water conservation world locally and at the state level, gave further explanation on the changing weather patterns that are impacting the basin and the amount of water available for irrigation.
Coombs pointed to the problem of overnight temperatures in the late fall and winter months, and the fact the Valley just isnโt getting the sub-zero temperatures it used to.
Look at December 2025, which saw an average daily low for the month of 11 degrees โ double digits overnight โ when the normal low for December is 0.8 degrees. January of this year had an average daily low of 4 degrees instead of the -1 that is a normal overnight low temperature for the month. It would have been higher than 4 degrees were it not for sub-zero overnight lows in 5 of the last 7 nights of January.
โWeโre not sunburning that much harder, weโre just losing the cold,โ Coombs said to his fellow farmers.
The timing of when the moisture comes is off, too. Look at the past two water years โ 2024 and 2025 โ when heavy rains in October came through and added to the total overall amount of water in the Rio Grande and Conejos River systems.
Too late to help irrigators, but good enough to help the amount of water in the Rio Grande and Conejos River, overall.
โLook at how itโs changing,โ Coombs said. โUseful water for irrigation is changing in more ways than just volumes. Weโre seeing timing change. So thatโs part of what this is. Mother Nature is playing a big role in this. Weโve got to figure that component out a little better. We donโt need to look across the fence at what our neighbors are or arenโt doing. Letโs figure out how we correct to that.โ

Sen. Mike Lee, the MAGAt from Utah, appears to be vying to be the most anti-public land politician in history. The Trump sycophant was, of course, behind last yearโs congressional bids to sell off public land to real estate developers and various other schemes. His latest assault is the Historic Roadways Protection Act, which passed through a Senate committee yesterday. It would block the Bureau of Land Management from โclosing historical roadsโ and implementing travel management plans across a broad swath of federal lands in Utah until a federal court rules on thousands of county RS-2477 claims.
RS-2477 is an 1866 statute that allowed highways to be constructed across federal lands to access mining claims and homesteads. It was repealed in 1976 when Congress passed the Federal Land Policy Management Act, or FLPMA. But FLPMA grandfathered in existing โhighwaysโ that had been constructed under RS-2477. In 2010 and 2011, Utah and its counties filed some 12,000 RS-2477 claims on about 35,000 miles of โhighwaysโ on federal lands, many of which are no more than old livestock tracks, in hope of gaining control of the paths so they can grade them, widen them, and even pave them. Settling all of these claims could take decades, meaning Leeโs bill would essentially be banning the BLM from managing travel on these areas forever.
Albert Bacon Fall, the New Mexico Senator and disgraced Interior Secretary under President Warren G. Harding still has my vote for the most anti-public land politician. But maybe thatโs because Fall was actually a colorful character. Leeโs most interesting trait is that he holds Jell-O socials in his Capitol office.
One of the things I like about Page, Arizona, are the weird and ubiquitous contrasts that characterize the place. Thereโs the surreality of a lakeside city in the desert and the striking juxtaposition of golf course greens against stone. But perhaps the most jarring of all is the sensation of wandering Safewayโs aisles in a distinctly American town and hearing fellow patrons speaking languages from all over the world.
The Southwest attracts visitors from across the globe and, as a result, the increasingly dominant tourism and outdoor recreation industries have come to depend on international travelers. After Trump was inaugurated and implemented his America First creed, which tends to manifest as hostility towards every other nation, international travel to the U.S. dropped. Thatโs in spite of the fact that Trumpโs economic policies have also caused the dollarโs value to plummet, making the U.S. a cheap vacation spot for Europeans.
Over the summer of 2025, that appears to have led to a drop in visitation to most national parks in the Southwest. However, visitation tended to rebound in the fall โ perhaps due to lower gas prices โ bringing the annual numbers back up to close to what they were in 2024.
One exception was Glen Canyon National Recreation Area, which saw a huge drop in visitors last year, probably due to a combination of low reservoir levels at Lake Powell, a massive wildfire on the Grand Canyonโs North Rim, and the drop in international visitation. But if tax revenues are any indication, it hasnโt hurt the overall tourism industry in Page that badly. Sales tax, hotel/motel tax, and online lodging tax revenues for January through September 2025 were up significantly from the previous year, according to the City of Pageโs statistics.
Grand Canyon NP and Glen Canyon National Recreation Area saw the biggest drops in year-over-year visitation in 2025, which may be due to a fire on the Grand Canyonโs North Rim and the drop in international travel to the U.S. Visitation continues to grow at Yellowstone, Grand Teton, and Olympic National Parks.

Arches National Park saw a marked decrease in visitation following the implementation of a timed entry system in 2022, but since then it has held steady and increased between 2024 and 2025. Most other Southwest national park units saw a decrease in visitation last year, however.

Youโll all be thrilled, Iโm sure, to learn that the uber-wealthy had a pretty good year in 2025, at least if high-end home and land sales are any indication. Luxury real estate sales in Jackson, Wyoming, reportedly are โsurgingโ and โclosed the year with exceptional momentum.โ Thatโs the latest from The Viehman Groupโs Jackson Hole Report, something I read when I want that lovely sensation of barfing in the back of my mouth.
Thirty-seven homes sold for over $10 million in the region last year, with 25 of them netting a sale price of over $15 million. The most expensive home sale was the Bar B Bar Ranch 4, with โmultiple enhanced spring creeks for fishing,โ which went for a modest $43 million.
But donโt worry! Overpriced luxury homes remain for the taking! For instance, you can buy a glorified quonset hut โ er, an 8,583-square-foot steel, glass, and stone mansion โ for $60 million. I know that seems like a lot, but according to Zillowโs BuyAbility calculator, the monthly payments would be a mere $320,673 after a $12 million down payment.
The median earnings for full-time year-round workers in Teton County are about $70,000 per year, which, according to Zillowโs mortgage calculator, could allow one to afford a $220,000 home with a $10,000 down payment. Meanwhile, the median home sale price in Teton County is about $3.8 million. And the cheapest home on the market is a 1970s, 644 sf condo listed for $695,000 (after a $30k reduction).
So, yeah, the Westโs housing affordability crisis is as bad as ever, and the gap between the uber-rich and everyone else continues to grow.

The Abundance movement has reached the Colorado River, brought by an unexpected flag-bearer. The motorized recreation organization, BlueRibbon Coalition, is proposing the Colorado River Abundance Act. The vision, writes the coalition, is simple: โThe American Southwest does not have to settle for managing a dwindling resource. It can choose abundance and start building.โ
Building what? You ask. The answer: โA coordinated suite of desalination plants โ offshore, onshore, and binational โ supported by pipelines, pumping systems, brine-management facilities, and sediment removal programs.โ These plants would crank out as much as 7 million acre-feet of water per year and deliver it to the river and/or directly to Lower Basin water users. That would allow more water to stay in Lake Powell and Lake Mead, thereby buoying reservoir levels.
And that would, among other things, improve boating and other recreation on those reservoirs, which is why the BlueRibbon Coalition is pushing the concept. In addition to creating funds for building a massive amount of water desalination and transportation infrastructure, the proposed legislation would also โelevate recreation to a coequal project purpose, establishing Recreation Modernization Plans for key reservoirs,โ and pushing major upgrades to marinas, launch ramps, docks, trails, and shoreline facilities, โincluding a top-priority requirement to rebuild mid-lake services at Lake Powell with fast-track approval.โ
Thatโs referring to the late Dangling Rope Marina, a remote floating boat refueling and restocking station in Dangling Rope Canyon, located about halfway between the down-lake marinas and Halls Crossing in the upper section of the reservoir. But low water levels and a damaged electrical system forced the National Park Service to shutter it in 2021, and it has not been reopened or replaced.
This abundance approach could work, in theory. But consider this: the largest desalination plant in the world, Ras Al Khair in Saudi Arabia, can treat about 306,500 acre-feet of water per year. It reportedly cost about $7 billion to construct, and uses about 3,626 megawatt-hours of electricity each day โ that adds up to 1,323 gigawatt-hours annually, or enough to power tens of thousands of homes (or a handful of data centers). Youโd need about 20 of those leviathans and a crapload of generation capacity to reach the 7 MAF/yr target of this plan, not to mention the extensive pumping and piping infrastructure to get the water to where it needs to go.
At some point, doesnโt it seem just a little bit easier, and a hell of a lot less expensive, to live within our means?
I will say that the Abundance approach is a step up from a, letโs say Archimedean, proposal to raise Lake Powellโs level by, wait for it, throwing a bunch of car batteries into the reservoir. If youโre wondering if this was a serious idea or not, just consider from where it came: The Sonoran Avalanche Center.

The Land Desk has been talking a lot about the effects the low snowpack will have on water supplies, Lake Powell, and irrigators.

The American Westโs snowpack is valuable for many reasons.
Snowmelt supplies much of the water flowing through the regionโs streams, rivers, irrigation canals and household faucetsโa vital role that has taken on new urgency this winter as much of the West struggles with scant snow cover.
Snowfall supports countless species, maintains forest health and helps keep a lid on wildfires. It even cools the planet by reflecting sunlight.
Snowflakes also underlie the regionโs multi-billion-dollar winter sports industry, fueling local economies and drawing millions of participants. In warmer months, boating and fishing depend on water that was once frozen.
Snow performs all these functions, but can its worth be calculated in dollars and cents? And how is climate change affecting that value?
Like many aspects of nature, snow is easier to monetize in some domains than others. Its ecological benefits are complex, and its aesthetic qualities are subjective: some Westerners love the ice crystals, others dread them.
But in the economic realm, researchers have attempted to put a dollar figure on the regionโs snow, and the numbers theyโve generated are huge.
โThis stuffโs worth trillions, not billionsโ of dollars, said snow scientist Matthew Sturm, lead author of a widely cited 2017 paper in Water Resources Research that estimated the value of the water embedded in the Westโs snowpack. โI turn on the tap in the Western statesโwhat comes out of it is mostly snow.โ
The Colorado River, which supplies drinking water to tens of millions of people and irrigates vast croplands, is primarily driven by snowmelt. The river generated an estimated $1.4 trillion in annual economic activity, according to a 2014 report commissioned by Protect the Flows, a business coalition, and conducted by Arizona State University. Adjusted only for inflationโnot the regionโs growthโthat figure was equivalent to about $1.9 trillion in 2025, underscoring the high stakes of the ongoing, contentious negotiations over how to manage the Colorado River.
For some researchers, assigning a dollar value to snow is more than an academic exercise. In an era of tightening budgets and federal cutbacks in science, economic estimates can help justify investments in monitoring and studying snowโand highlight how much is at risk as the climate warms.
โIf you want society to respond, you better talk about things that are fairly immediate, right at peopleโs doorsteps, and are easy to explain,โ said Sturm, a professor of geophysics at the University of Alaska Fairbanksโ Geophysical Institute and the author of A Field Guide to Snow.
Or as Sturmโs paper puts it, โthe โkiller argumentโ to the wider public that vigorous snow research is important would come by framing the argument in terms of money, something everyone understands.โ
Peer-reviewed studies explicitly valuing the snowpack are rare, but some analyses have also calculated the sizable economic impact of snow sports. This winter, skiing and snowboarding in the West have been constrained not only by a lack of snowfall but also by record warmth that limited some resortsโ ability to make artificial snow.
A 2024 report from the National Ski Areas Association concluded that downhill snow sports generate $58.9 billion in annual economic activity in the United States and support an estimated 533,000 ski and snowboard jobs nationwide.
While the snowpack delivers tangible economic benefitsโsome easier to price than othersโsnowfall also carries real costs. Any accounting of snowโs economic impact must also reckon with the damage it causes.
Winter weather contributes to fatalities from avalanches in the mountains and from heart attacksin cities among people shoveling snow. But those deaths pale in comparison to the toll on slick roads. Each year, 24% of weather-related vehicle crashes happen on snowy, slushy or icy pavement, and 15% occur when snow or sleet is falling, according to the Federal Highway Administration. More than 1,300 people are killed and more than 116,800 are injured each year in crashes on snowy, slushy or icy pavement, the agency reports, though not all of those incidents are weather related.

Valuing the snowpackโs water
The 2017 paper began with a phone call that Sturm made to Michael Goldstein, a professor of finance at Babson College with whom he had previously collaborated.
โHey, what do you think snowpackโs worth?โ Goldstein recalled Sturm asking.
Goldstein wasnโt a snow expert, but he told Sturm, โIf we make some simplifying assumptions here, I could value it for you.โ
โI just thought it was a cool question,โ said Goldstein, who is also the Donald P. Babson Chair in Applied Investments at Babson.
Since its publication, the study has been cited nearly 400 times, according to Google Scholar.
Viewed through an economic lens, the snowpackโs role as a mountain water tower provided a clear value that Goldstein could quantify.
โNature naturally stores the water for you for free. You didnโt have to build a reservoir,โ Goldstein said. โIf that goes away, that actually has a cost. And the cost is the replacement cost of either storing the water or getting water from a different source.โ
Climate change is already having a variety of profound effects on the Westโs snow, such as shrinking the snowpack season, but the study focuses on one key impact: the shift from snow to rain as temperatures rise.
Even if total precipitation remains unchanged in the decades ahead, a transition from snow to rainโand faster melting of the snowpackโmeans runoff will occur earlier in the year. In much of the West, however, it may be impossible to capture all that earlier water for later use because dam managers must leave enough empty space in reservoirs to reduce the risk of catastrophic flooding.
โThere is not enough reservoir storage capacity over most of the West to handle this shift in maximum runoff and so most of the โearly waterโ will be passed on to the oceans,โ according to a 2005 study.
To estimate the declining value of the snowpack in a warming climate, the 2017 paper made some assumptions about the transition from snow to rainโan evolution expected to be more pronounced in warmer regions such as California and Oregon than in colder locations like the Northern Rockies.
Examining a range of future trajectories spanning five to 100 years, the researchers assumed that half of current snowfall would fall as rain by the end of the scenario.
For the 50% of snow that would eventually convert to rain, some of the water could be captured by existing reservoirs. But while Lake Mead and Lake Powell on the Colorado River currently have plenty of room to spare, the authors note that โvirtually every report we have found on the heavily dammed water systems of the West suggests that reservoir capacity (except when immediately following drought) is maxed out.โ As a result, the paper assumes that water systems would lose two-thirds of the reduced snowmelt runoff.
โWeโre losing, essentially, the storage capacity of snowโmeaning in lieu of snow, we get rain,โ Sturm said.
With their estimates of the amount of water lost as snow shifts to rain, the researchers could then multiply those figures by the cost of water to begin determining the decline in monetary value. The paper uses two water prices to bracket its estimates: $200 and $900 per acre-foot (an acre-foot is the volume of water needed to cover an acre of land to a depth of 12 inches, or 325,851 gallons).
In reality, Goldstein said, the price of water would rise as supplies became scarcer. But the paper holds water prices constant over time, an assumption that yields a conservative estimate of the snowpackโs value.
This map shows the share of annual precipitation that falls as snow over land, based on data from 2000 to 2010. In the Northern Hemisphere, the area where 40% or more of precipitation falls as snow covers more than 5.8 million square miles. At its peak, snow typically blankets more than 22 million square miles of the Northern Hemisphere. Source: Drew Slater, National Snow and Ice Data Center, via Sturm et al. (2017).
Discounting the future
The price of water varies greatly across the West, so estimates of the snowpackโs value will necessarily span a broad range. But water costs arenโt the only reason itโs challenging to pin down the snowpackโs monetary worth.
Another challenge the paper grapples with is the changing value of money over time. Even in the absence of inflation, if someone offered you $100 right now versus $100 in a year, the economically rational choice would be to take the $100 today. After all, a lot can happen in a yearโand you could invest the $100 in the meantime. But what if the offer were $105 or $110 a year from now?
To convert future benefits into todayโs dollars, economists use a โdiscount rateโ that accounts for risk and the preference for receiving payments sooner rather than later. A discount rate is โlike the foreign exchange rate between consumption today and consumption tomorrow,โ Goldstein said.
The choice of the discount rate can make a big difference in how future costs or benefits are calculated, and itโs often a pivotal factor in studies of the economics of climate change. In the snowpack paper, the authors use three discount ratesโ1%, 3% and 6%โalthough they omit the 6% rate in their final valuation โbecause it is fairly extreme and unlikely to be correct in a water-stressed future world.โ
The higher the discount rate, the more heavily future losses are discounted, reducing the economic justification for acting today, such as acquiring new water supplies or building additional reservoirs.
Assumptions about the discount rate, the price of water and future climate trajectories all weigh heavily on estimates of the value of the snowpackโs water. In summary, the authors conclude that about 162 million acre-feet of water is deposited as snow in Western mountains each winter. If half of that snowfall were to fall as rain in the futureโand two-thirds of that water were to run off to the ocean without being capturedโwater systems would lose roughly 53.9 million acre-feet per year. That volume is roughly the combined storage capacity of Lake Mead and Lake Powell, the nationโs two largest reservoirs.
The total replacement cost for the lost water ranged from $120 billion to $4.76 trillion, according to the 2017 study. By comparison, the federal governmentโs budget totaled about $3.85 trillion in fiscal year 2016.
โTo date, a full financial evaluation of the importance of snow in our lives has not been made, but computations here and elsewhere indicate it is on the order of trillions of dollars,โ the authors write.
The snowpackโs importance and value vary across the West, with some watersheds more dependent on snowmelt than others. To estimate the local impacts of future snowpack losses, researchers used data from the 2017 study and another paper to create an interactive map that shows the share of water in each Western river basin derived from snow and lets users adjust key variables, including the discount rate, the price of water and the rate at which snow transitions to rain.

Investing in snow science
Jessica Lundquist, a professor of civil and environmental engineering at the University of Washington, called the paper โinteresting and unique.โ Lundquist, who wasnโt an author of the study but is acknowledged for advising the researchers, said the paper not only tried to put a dollar value on the snowpack but โalso was trying to put a value on the knowledge.โ
โI like the paper because it was a collaboration between a snow scientist and an economist,โ Lundquist said. While the estimates of the snowpackโs value are uncertain, Lundquist said the study provides a useful framework for assessing the financial implications of water management strategies.
In a commentary on the 2017 paper, subtitled โInvestments in snow pay high-dollar dividends,โ Lundquist wrote that the study โputs the value of snow one thousand times higher than the estimates of snow based on tourism alone.โ
When the commentary was published, snow scientists were trying to convince NASA to launch a satellite mission to study the snowpack.
โWe were often getting questions about what is the value not only of snow, but of studying snow,โ Lundquist said.
A satellite dedicated to monitoring snow never launched. But scientists continue to track the snowpack using other spacecraft, along with a suite of tools that includes aircraft, automated stations and manual measurements.
โI think weโre getting progressively better at figuring out how much snow is in the mountains,โ Lundquist said. โI think weโve made tremendous progress in the last 10 years that we can actually quantify it quite well with a number of ways.โ
In other parts of the world, however, snowpack monitoring may be very limited. โA lot of what still needs to be done is in other mountain ranges, other places that donโt have these observing networks,โ Lundquist said. โThereโs a lot of people who depend on water from the Himalaya who just have no idea whether itโs going to be a drought year or a flood year or what is upstream at all.โ

Recreational impact of a shrinking snowpack
Beyond supplying water, the Westโs snowpack also underpins the regionโs winter recreation economy.
During the 2024โ25 season, U.S. ski areas recorded 61.5 million skier visits, according to the National Ski Areas Association. This winter, however, visitation across much of the West has suffered amid a widespread snow drought.
In January, Vail Resorts, which is publicly traded on the New York Stock Exchange, reported that visits to its mountains so far this season were down 20% compared to last season, primarily because of poor snow conditions. In the Rockies, only about 11% of the companyโs terrain opened in December, when snowfall was nearly 60% below the 30-year average.
A number of studies have examined how changes in the snowpack affect ski areasโboth historically and in future projections.
Between 1999 and 2010, the U.S. downhill ski industry lost an estimated $1.07 billion in revenue between low- and high-snowfall years, resulting in 13,000 to 27,000 fewer jobs, according to a 2012 analysis by University of New Hampshire researchers. The report was commissioned by Protect Our Winters and the Natural Resources Defense Council, two advocacy groups.
A 2024 study estimated that U.S. ski areas lost more than $5 billion from 2000 to 2019 due to fewer visits and higher snowmaking costs. Compared to the 1960-1979 period, ski seasons from 2000 to 2019 shortened by 5.5 to 7.1 days, according to a model of operations at 226 ski areas.
Looking ahead, the study projected that by the 2050s, ski seasons would shrink by 14 to 33 days under a low greenhouse gas emissions scenario and by 27 to 62 days under a high-emissions pathway. Under those scenarios, annual industry losses ranged from $657 million to $1.35 billion.
The 2024 study accounted for the added expenses of snowmaking, which requires investments in equipment and labor while also increasing water and energy use. It did not, however, include the broader ripple effects of shorter ski seasons on surrounding communities, where hotels, restaurants, bars, retailers, and gas stations depend heavily on touristsโ spending.
A 2017 study examining future climate impacts on skiing and snowmobiling analyzed 247 winter recreation locations across the continental United States and projected how warming would shorten seasons. The authors concluded that โvirtually all locations are projected to see reductions in winter recreation season lengths, exceeding 50% by 2050 and 80% in 2090 for some downhill skiing locations.โ
Those shorter seasons โcould result in millions to tens of millions of foregone recreational visits annually by 2050, with an annual monetized impact of hundreds of millions of dollars,โ the researchers wrote. They also noted that limiting greenhouse gas pollution โcould both delay and substantially reduce adverse impacts to the winter recreation industry.โ
A smaller, less reliable snowpack can also affect summertime recreation by reducing streamflows and reservoir levels that support fishing, boating and other water-based activities.
In Colorado, for example, outdoor recreation accounted for 3.2% of the stateโs gross domestic product in 2023, according to the Bureau of Economic Analysis. Boating and fishing generated $689 million in economic activity in the state, while snow-related recreation was valued at $1.56 billionโmore than any other state.

Other benefitsโand costsโof snow
The snowpackโs importance to winter recreation and the Westโs water supply are among the easier values to quantify, but theyโre not the only benefits snow provides.
On a global scale, one of the most valuable functions of frozen water is that it reflects far more sunlight than bare ground or open ocean. This reflectivityโa property known to scientists as albedoโhelps cool the planet.
A 2013 study examining the thawing Arctic attempted to monetize the loss of that cooling effect. The decline in Arctic snow and iceโalong with increased methane emissions from melting permafrostโwas estimated to cost society $7.5 trillion to $91.3 trillion from 2010 to 2100. โThe frozen Arctic provides immense services to all nations by cooling the earthโs temperatureโthe cryosphere is an air conditioner for the planet,โ the scientists wrote.
Then again, the loss of snow could reduce some costs to society.
โThereโs some side benefits,โ Goldstein said. โYou might not have a flood because youโre not going to have a massive runoff all at the same time. That does happen. Some things will be reduced.โ
If snow disappeared, so too would snow days that disrupt travel and hamper economic productivity. Winter road maintenance accounts for roughly 20% of state transportation department maintenance budgets, according to the Federal Highway Administration, which estimates that state and local agencies spend more than $2.3 billion annually on snow and ice control annually.
Between 1980 and 2024, the United States experienced 24 winter storms that each caused more than $1 billion in damages, according to the National Centers for Environmental Information. Collectively, those disasters cost $104.2 billion and claimed 1,453 lives.
While vehicle crashes, skier visits and acre-feet of snowmelt can be quantified and priced, snowโs benefits and costs also encompass many things that are difficultโif not impossibleโto calculate.
In many ecosystems, for example, snow and snowmelt are vital for plants and animals that have their own economic value, not to mention their intrinsic worth. The 2017 snowpack study did not attempt to price these so-called ecosystem services, which include keeping forests healthy, maintaining cold-water fisheries and sustaining biological diversity.
Even more challenging to value are the mix of emotions that snow evokes. Beautyโand miseryโare in the eye of the beholder.
โSome people want their white Christmas,โ Lundquist said, โand others are like, please donโt shut down my city.โ

Colorado water groups want a seat at the table to weigh in on a historic Western Slope bid to purchase powerful water rights tied to a small power plant on the Colorado River.
Cities, irrigation districts, hydroelectric companies and other groups submitted filings Friday to have a say in a water court case that will decide the future of Shoshone Power Plantโs rights to access water.
The Colorado River Water Conservation District submitted a request to the court in November to change the water rights tied to the power plant, a small facility tucked into Glenwood Canyon by Interstate 70. The water is used primarily to generate electricity, but the district wants to add an environmental use to help aquatic species during low flows or if the 117-year-old power plant a few miles east of Glenwood Springs were to shut down in the future.
Historically, groups have used opposition filings, like those made Friday, as a way to weigh in on water cases โ it doesnโt necessarily mean they oppose all or any part of the proposal, the Colorado River District said.
The district declined further comment.
If the districtโs bid is successful, it will end up buying the Shoshoneโs water rights from an Xcel Energy subsidiary for about $99 million. The water rights would become the crown jewel of a state-led environmental preservation program and provide long-term certainty for water users across the state.
If the district cannot get court approval to change the water rights, it would scuttle the Colorado River Districtโs entire proposal.
Of the 60-plus parties in the case, some, like several major Front Range cities, have been concerned the water supplies for millions of people could be negatively impacted. Others filed mainly to watch or to support the effort.
These filings came from Western Slope irrigation districts, governments and water utilities, including Grand County, Breckenridge, Clifton Water District, Orchard Mesa Irrigation District, Summit County and Glenwood Springs.
โEagle County filed as an โopposerโ because that is the term thatโs used in water court for parties with an interest in the outcome of the case,โ according to a statement from Eagle County staff. โIn this case, the county has an interest in maintaining the existing Shoshone Water Rights flow regime as described in the application for change of water rights.โ
Others watched to make sure their priorities were discussed during the hearings.
โWestern Resources Advocates joined the Shoshone water rights change case as part of our ongoing work to preserve and improve the natural environment in the Colorado River in Colorado,โ Bart Miller, WRAโs healthy rivers director, said in an email to The Colorado Sun.
The proposed change would also help support recommended flows for endangered fish many miles downstream, he said.
Some filings came from big water players on the Front Range who fought against the Colorado River Districtโs proposal during a state process to approve the environmental use. These include the city of Colorado Springs, Northern Colorado Water Conservancy District, the city of Aurora and the city and county of Denver.
These groups have cited concerns that changes in the water rights at Shoshone could impact their own water supplies, which are used by over 2.5 million people up and down the Front Range.
Shoshoneโs oldest water right is more senior than some of the Front Range water rights, which allows it to use water first. Under Colorado water law, junior rights get cut off first in dry years.
Adding an environmental use might mean Shoshone is using water more frequently or in larger amounts than in the past, the providers argued.
Others joined to better follow the case, like the city and county of Broomfield and Southwestern Water Conservation District. The district, like the Colorado River District, was formed by the state legislature to act as stewards of water resources on the Western Slope.
โGenerally we are in favor of the Shoshone water change,โ Steve Wolff, SWCD general manager, said. โWeโre watching โฆ how the water right ultimately may have a role in interstate matters.โ
There is a lot to be determined about the future of Shoshoneโs water rights.
The Colorado River Districtโs plan to buy the rights comes with four stipulations: state approval to use the water to help instream flows; a successful petition in water court to change the legal rights; $99 million to pay the bill; and approval from the Colorado Public Utilities Commission.
The court case will identify how much water could be used to benefit the environment and identify any potential ways a change could harmfully impact water flows to farmers, cities, utilities or other water users.
โFrom a legal perspective, this potentially could be a landmark water case,โ Wolff said. โWe will certainly be involved in it.โ
Financing for a potential sale is still to be determined: In January 2025, the Bureau of Reclamation offered $40 million in federal funding through a program authorized by the Inflation Reduction Act. But President Donald Trumpโs administration froze that funding.
If the Colorado River District gets its way in court, theyโll take it to the utilities commission for consideration. The entire process could take years to finalize.
Continued drought conditions plagued much of the region during January. After significant regional precipitation during the first week and a half of January, dry conditions dominated, and little precipitation fell during the remainder of the month. Consequently, regional snowpack and streamflow volume forecasts are extremely low. Record low statewide snowpack conditions exist in Colorado and Utah while Wyoming statewide SWE is 84% of average, driven by wetter conditions in western and northern Wyoming. While northern Wyoming streamflows are near to above average, much below average streamflow volumes are forecasted for the remainder of the region including Lake Powell which is forecasted to receive 38% of average inflow. With Lakes Mead and Powell storage hovering just above 25%, forecasts of low Colorado River flows, and continued Post-2026 Guidelines negotiations, 2026 is certain to be a challenging year for regional water managers.
January precipitation was much below normal for the majority of Colorado, Utah and Wyoming and over three-quarters of the region received less the 75% of average precipitation. Small areas of near average precipitation fell in all three states and eastern Colorado received 125-400% of average January precipitation.
Temperatures were above average across the entire region during January. January temperatures in all of Utah and Wyoming and large portions of Colorado exceeded three degrees above average. Northwestern Colorado, northeastern Utah and western Wyoming observed January temperatures that were six to twelve degrees above average.
February 1st snowpack conditions were poor across most of the region. Colorado and Utah snow water equivalent (SWE) was 55% of median at the start of February and at record low levels. Snowpack conditions in Wyoming are slightly better with 84% median SWE statewide. Western Wyoming river basins (Bighorn, Green, Snake, and Yellowstone) had near median SWE. Regional snowpack conditions generally deteriorate from north to south with the worst snowpack conditions in the Arkansas, Rio Grande, and San Juan River basins where less than 50% median SWE has accumulated. Real-time estimates of SWE based on satellite imagery suggest significantly poorer snowpack conditions compared to SNOTEL measurements of SWE. These spatial estimates of SWE often differ from SNOTEL SWE measurements because they capture SWE across the entire elevation range while SNOTEL measures SWE across a narrower elevation range. In Utah, February 1 river basin percent SWE varied from 12-54% of average; in Colorado, basin percent SWE ranged from 19-54%; and in Wyoming, basin SWE ranged from 4-110%.

Seasonal streamflow volume forecasts for river basins in Colorado, Utah and southeastern Wyoming are much below average. Near to above average seasonal streamflow volumes are forecasted for much of Wyoming. In the Upper Colorado River Basin, streamflow volume forecasts ranged from 30-92% of average and seasonal inflow volume to Lake Powell is forecasted at 38% of average (2.4 million acre-feet). The Upper Green River Basin and other northern Wyoming basins (Big Horn, Powder and Yellowstone) are forecasted to receive 92-122% of average streamflow volumes. On the Great Basin side of the Wasatch Mountains and Plateaus of Utah, streamflow volume forecasts ranged from 35% of average for the Weber Basin to 54% of average for the Six Creeks watershed in Salt Lake County. Similarly, low streamflow volume forecasts were issued for the Arkansas (63%), Noth Platte (58%) and South Platte (76%) River Basins.
Dry and warm conditions during January caused regional drought coverage to increase to 63% (54% of region on 12/30/25). Drought conditions especially deteriorated in Colorado, where moderate drought emerged in northeastern and southwestern Colorado and severe drought expanded in western Colorado. The area of extreme and exceptional drought in the Colorado River headwaters increased in area during January. Drought emerged in eastern Wyoming and severe drought expanded in the southern portion of the state.

As of mid-January, La Niรฑa conditions persist in the eastern Pacific Ocean. Pacific Ocean conditions are expected to warm and there is a 69% probability of neutral conditions emerging in the next two months. Despite the forecast for warming Pacific Ocean temperatures, ocean temperatures decreased slightly in late January. NOAA monthly forecasts for February suggest an increased probability for below average precipitation across the entire region and above average temperatures for Colorado, Utah and southwestern Wyoming. On the three-month timescale, NOAA forecasts indicate an increased probability of below average precipitation in southern Colorado and southern Utah. February-April temperatures are likely to be above average in Utah and southwestern Colorado.
Significant weather event: Upper Colorado River Basin drought.ย The Upper Colorado River Basin (UCRB) began the 2026 water year with severe or extreme drought conditions covering nearly the entire watershed. Drought conditions have eased slightly, largely due to a wet October, but basin SWE is currently at 60% of median which is a record low (since 1986). If an average amount of SWE accumulates in the UCRB from February 10 to early April, then the 2026 peak SWE would remain low at 77% of average. Poor snow conditions and relatively dry soils throughout much of the UCRB have resulted in very low (38% of average) Colorado River inflow forecasts to Lake Powell. With a current Lake Powell elevation of 3,535 feet and poor Colorado River streamflow volume forecasts, low reservoir elevations will threaten Glen Canyon Damโs ability to generate electricity by the end of 2026. The US Bureau of Reclamationโs 24-Month Study projects Lake Powell elevations two years into the future. Under the โMost Probableโ scenario, Lake Powell elevation falls to 3,513 feet, just 23 feet above the elevation that the hydroelectricity-generating turbines must be shut down. Under the โMinimum Probableโ scenario, reservoir elevations fall to 3,490.6 feet, just inches above the level that power generation at Glen Canyon Dam must cease. Operating Glen Canyon Dam is possible below 3,490 feet, but electrical generation must be bypassed and the alternate outlet for the dam was not engineered to run continuously. With Lakes Mead and Powell sitting at one-third and one-quarter full, only 15 million acre-feet (MAF) of combined water storage exists. However, only 6.3 MAF is available for consumption since nearly 9 MAF of water sits below the deadpool elevation of the reservoirs (Colorado River Research Group, “Dancing with Deadpool“). That means that current accessible storage in the two large reservoirs is less than one year of Lower Basin water deliveries from Lake Powell (7.5 MAF). While the UCRB has faced significant drought challenges over the last 25 years, current and forecasted conditions are taking the basin into truly unprecedented waters.
Coloradoโs snowpack has remained at the zeroth percentile since about Jan. 15, 2026. While this snow telemetry data shows a record-low snowpack, longer term snow course measurements show the years of 1976-77 and 1980-81 may have been worse. Credit: NRCS

February 6, 2026
At some long-term snow measurement sites, the winters of 1976-77 and 1980-81 were worse than this year, but not by much
Across Colorado, the stateโs array of snow telemetry, or SNOTEL systems, have documentedย record-low snowpack conditionsย in numerous river basinsย and on a statewide levelย several times this winter. Since about Jan. 15, the snow telemetry system has had Coloradoโs snowpack statewide sitting at the zeroth percentile, or the worst on record compared to the 30-year period from 1991 to 2020…
โWeโve been stuck for the most part in this warm and dry pattern across the West, going back really to the fall,โ Colorado Climatologist Russ Schumacher said. โThe snowpack numbers pretty much everywhere in Colorado are pretty ugly right now.โ

But going back in Coloradoโs history, 1976-77 and 1980-81 are two winters often considered โthe worstโ for snow. Schumacher noted that the stateโs snow telemetry system only began to be built out in the 1980s, so comparison can be difficult. Thatโs where snow course measurements come in.ย Snow course measurements, which have been taken by hand about once a month at some sites in Colorado since the 1930s, allow for more direct comparisons to those historically bad snow years.
โThat allows you to actually make some comparisons to those really, really awful years from the 76-77, 80-81 that the longtimers there in the mountains will remember,โ he said. โThis yearโs not as bad as those, but in a lot of places, itโs the second or third worst when you include those years.โ
At Independence Pass, one site where snow course measurements have been taken for well over half a century, this is the second-worst snowpack on record, according to the data. The only year when Independence Pass had a worse snowpack was the winter of 1976-77. At a snow course measurement site in Blue River in Summit County that has about 70 years of data, this year was also the second-lowest snowpack on record, behind only the winter of 1980-81…Yet, at a snow course measurement site at Berthoud Pass, this year is only the 12th worst on record. The worst February snowpack on record at Berthoud Pass was, once again, during the winter of 1980-81.

There is another emerging issue that decades of drought and the warming climate is causing in the San Luis Valley โ elevated levels of heavy metals in drinking wells that can cause health issues for households that rely on them.
Itโs a topic Kathy James, Ph.D., and associate professor with the Colorado School of Public Health, knows well after spending the past three years working with families in the Valley that rely on private drinking wells.
James provided an update to the work during Tuesdayโs opening day of the 2026 Southern Rocky Mountain Ag Conference. She reported that 15 to 25 percent of the private groundwater wells used for drinking water in the San Luis Valley contain elevated levels of arsenic, uranium and other heavy metals.
Her confidence in the findings is bolstered by the fact that 850 households in the different counties of the Valley participated in the study and provided samples to help James and her team evaluate the effect drought is having on water quantity and water quality.
โThe comprehensive information that we have about distribution of metals across the Valley is by far one of the best weโve seen in most western states that do experience elevated metals,โ James said.
She noted how low snowpack impacts the age of water underground and ultimately the quality of water people are drinking from a private well.
The Upper Rio Grande Basin, like the Colorado River, is suffering from snow droughtsin the high elevations of the west and below-normal spring runoff levels.
Less snow, less spring runoff for recharge of the aquifers, and higher levels of arsenic, uranium and other heavy metals is the emerging issue. James talks more about the study and the teamโs findings in the next episode of The Valley Pod, which streams Wednesday on AlamosaCitizen.com.
Under pressure to provide water for drinking and irrigation, people around the globe are trying to figure out how to save, conserve and reuse water in a variety of ways, including reusing treated sewage wastewater and removing valuable salts from seawater.
But for all the clean water they may produce, those processes, as well as water-intensive industries like mining, manufacturing and energy production, inevitably leave behind a type of liquid called brine: water that contains high concentrations of salt, metals and other contaminants. Iโm working on getting the water out of that potential source, too.
However, most of these methods require strict environmental protections and monitoring strategies to reduce harm to the environment.
For instance, the extremely high salt content in brine from desalination plants can kill fish or drive them away, as has happened increasingly since the 1980s off the coast of Bahrain.
Brine injected into the earth in Oklahoma, including into wells used for hydraulic fracking of oil and natural gas, was one of several factors that led to a 40-fold increase in earthquake activity in the five-year period from 2008 to 2013, as compared to the preceding 31 years. And wastewater has been documented to leak from the underground wells up to the surface as well.
Researchers like me are increasingly exploring brineโs potential not as waste but as a source of water โ and of valuable materials, such as sodium, lithium, magnesium and calcium.
Currently, the most effective brine reclamation methods use heat and pressure to boil the water out of brine, capturing the water as vapor and leaving the metals and salts behind as solids. But those systems are expensive to build, energy-intensive to run and physically large.
Other treatment methods come with unique trade-offs. Electrodialysis uses electricity to pull salt and charged particles out of water through special membranes, separating cleaner water from a more concentrated salty stream. This process works best when the water is already relatively clean, because dirt, oils and minerals can quickly clog or damage the membranes, reducing the performance of the equipment.
Membrane distillation, in contrast, heats water so that only water vapor passes through a water-repelling membrane, leaving salts and other contaminants behind. While effective in principle, this approach can be slow, energy-intensive and expensive, limiting its use at larger scale.

A look at smaller, decentralized systems
Smaller systems can be effective, with lower initial costs and quicker start-up processes.
At the University of Arizona, I am leading the testing of a six-step brine reclamation system known as STREAM โ for Separation, Treatment, Recovery via Electrochemistry and Membrane โ to continuously reclaim municipal brine, which is salty water left over from sewage treatment.
The system combines conventional methods such as ultrafiltration, which removes particles and microbes using fine filters, and reverse osmosis, which removes dissolved salts by forcing water through a dense membrane, alongside an electrolytic cell โ a method not typically employed in water treatment.
Our previous study showed that we can recover usable quantities of chemicals such as sodium hydroxide and hydrochloric acid at one-sixth the cost of purchasing them commercially. And our initial calculations indicated the integrated system can reclaim as much as 90% of the water, greatly reducing the volume of what remains to be disposed. The cleaned water in turn is suitable for drinking after final disinfection using ultraviolet or chlorine.
We are currently building a larger pilot system in Tucson for further study by researchers. We hope to learn if we can use this system to reclaim other sources of brine and study its efficacy in eliminating viruses and bacteria for human consumption.
