Colorado’s 2026 water year this far has been defined by records across nearly every metric: an anomalously early snowpack peak, rapid melt driven by record March temperatures, snowpack that tracked at-or-near the lowest values in the SNOTEL period of record from January through May 1, and near-record early season precipitation in the San Juan Mountains. Runoff has arrived weeks ahead of the historical median across river systems and recession is largely underway.
May through July runoff forecasts remain low across Colorado at 24 percent of median at the 50 percent exceedance forecast. Western slope forecasts range from 22 to 24 percent of median and eastern basins remain slightly higher at 37 percent in the South Platte basin and 33 percent in the Arkansas basin (Figure 1). The Upper Rio Grande basin is forecast 30 percent of median at the 50 percent exceedance. Forty-eight of 86 forecast points rank as either the lowest or second lowest in their period of record. All 86 forecast points rank at or below the 13th percentile with a median percentile rank of 2. Several Colorado Headwaters forecast points rank lowest on record, including Colorado River near Cameo forecast a departure of 1.49 million acre-feet (MAF), rank 1 of 73 years.
Figure 1. Primary period streamflow forecast volume at the 50 percent exceedance probability, percent NRCS 1991-2020 median, May 1, 2026.
Statewide snowpack is 20 percent of median as of May 1, effectively unchanged from April 1 despite near-normal April precipitation. Snowpack peaked in early March in southern basins and mid-March in northern basins, three to five weeks ahead of historical median peak timing at half of median peak snow water equivalent (SWE). Early May storms have boosted statewide snowpack to 25 percent of median as of May 7, with sites in the Front Range east of the Continental Divide being particularly favored and receiving near 2 inches of SWE.
Many observed streamflow hydrographs are already entering recession unusually early. On the Yampa River near Maybell, seasonal peak flow occurred at the end of March and ranks as the earliest peak date and lowest peak in the 110-year period of record. Similar early and shortened hydrographs have developed in the Upper Colorado Region and in southern basins as accelerated spring melt caused much of the seasonal runoff to occur earlier than normal.
Statewide reservoir storage is 85 percent of median, while forecast inflows into Colorado’s largest reservoirs are well below median. Forecast inflows for the May-July 50 percent exceedance outlook range from 17 percent of median at McPhee Reservoir and 18 percent Blue Mesa to 36 percent at Lake Granby and Pueblo Reservoir.
April storms briefly stabilized snowpack conditions but did not offset the impacts of the record warm and dry winter and the late March heat wave that accelerated snowmelt and shifted runoff weeks ahead of normal. Future weather remains a source of uncertainty and the current 8-14 day outlooks favor above-normal precipitation alongside above-normal temperatures statewide.

To: Any Direct Flow or Stored Water User
From: Colorado Water Trust
Dear Water Users,
Colorado Water Trust works statewide to restore water to Colorado’s rivers. We wanted to take a moment to recognize the historic drought we are facing this year. We operate streamflow restoration projects in many different basins, some of which use water rights permanently decreed to protect water in the river, and many of which are temporary water sharing agreements with agricultural, municipal, and industrial water users.
We understand that many of our temporary water sharing agreements may not operate to restore streamflow this year—the agricultural partners with whom we have agreements may not have enough water for their own use. Those considerations are built into our agreements and we always respect our partners’ operational needs. It has also come to our attention that there may be people interested in using their water rights to prop up streamflow this year. Others may have insufficient supply and want to safeguard water that would otherwise be unproductively diverted. We prepared the following information for people in these situations:
Water Sharing
Colorado Water Trust can help you determine whether your water rights will help to save fish and streamflow this year if you want to leave your water in the river.
Administrative Approval
If your water rights could benefit streamflow, we can secure administrative approvals from the appropriate state agency or water conservation district.
Protection Against Abandonment
The statutes Colorado Water Trust works with for administrative approval provide clear protection against abandonment or any diminishment to the HCU of your water right.
Compensation
Colorado Water Trust provides compensation to partners in our ongoing water sharing agreements. We will do our best to secure compensation for any neew agreements, but whether we can provide compensation this year will depend on demand. Please feel free to reach out to us at RFW@ColoradoWaterTrust.org for more information, call (720)570-2897 x2, or visit our website, ColoradoWaterTrust.org. This is a hard year for all of us in the water community, and we would like to help water users and rivers wherever we can.

May 8, 2026
Very dry and warm weather in the winter and early spring means Colorado River flows into Lake Powell will hit record lows this summer, a new federal forecast says. The past winter brought record-low snowpack in the mountains of Colorado, Utah and Wyoming that feed the Colorado. March brought record heat that caused the snows that had fallen to melt prematurely. The result is that runoff from the melting snow into the river will bring April through July flows into Powell to only 13% of average, says the federal Colorado Basin River Forecast Center, a division of the National Oceanic and Atmospheric Administration. That would make the spring-summer runoff into Powell the lowest of its kind since Lake Powell was created in 1963 by the construction of Glen Canyon Dam. The total amount of water expected to reach Powell is 800,000 acre-feet from April through July.

In March, a month traditionally known for heavy mountain snows and dreary lower-elevation weather, a heat wave settled across the West, shattering temperature records from Tucson, Arizona, to Casper, Wyoming.
Yet not only did Western locations set new March highs; many exceeded temperature records for May. And those high temperatures kept hanging on, said Zachary Labe, a climate scientist at the nonprofit science center Climate Central, for nearly two weeks.
While heat waves are a natural phenomenon, this was the earliest and most widespread one ever recorded in the Southwest. And it was caused by climate change, which is making intense heat waves much more likely. Researchers say this means understanding their fallout is even more important.

Scientists are just now beginning to understand the ramifications of a devastating 2021 heat wave, when a massive heat dome brought 120-degree temperatures to the Pacific Northwest, causing widespread ecological damage. Tens of thousands of trees died. Baby birds that could not yet fly plummeted to the ground as they tried to escape the heat. Salmon and trout suffocated in small streams. Millions — perhaps even billions — of mussels and barnacles cooked.
This year’s heat wave may not have had the same immediate ecological impacts, but it comes on the heels of an already record-breaking hot, dry winter. Researchers say 2021 holds lessons about what lies ahead for both vulnerable and resilient species. Ecosystems, they warn, are likely to permanently change as some species simply can’t handle the heat.
FULLY UNDERSTANDING the impact that events like heat waves have on long-lived tree species takes time. Research is now trickling out from places like Washington, Oregon and British Columbia, and it’s not good.
The 2021 heat wave either killed or otherwise harmed more than three-quarters of species surveyed, including by limiting their reproductive success, according to Julia Baum, a professor at University of Victoria who co-wrote a recent paper on the long-term impacts. The hardest hit, perhaps unsurprisingly, were those unable to move to seek shade or cooler temperatures. Marine species like acorn barnacles and green rope seaweed fared the worst, as did kelp, surfgrass and rockweed.
“The rocky shorelines they live on heated up to (122 Fahrenheit). Think of being glued to hot concrete on the most scorching summer day: They essentially baked and died,” said Baum. “On land, wildflowers wilted and died, preventing entire populations from reproducing that year, and there was widespread leaf scorch and death in forests.”
Some species that could move modified their behavior: Ferruginous hawks reduced their flight time by about 81%, while wolves moved around more, perhaps seeking hunkered-down prey like mule deer and moose.
Meanwhile, species already adapted to hotter or more variable temperature ranges adjusted better than others.
The heat wave’s timing also mattered, said Adam Sibley, a remote sensing scientist and co-author of a 2025 paper that examined the impact on trees and forests. Plants tend to acclimate to heat throughout a season, so the triple-digit temperatures that struck in June hit harder than they would have in August.

So many tree needles died, in fact, that when Sibley drove to the Oregon coast with friends a few days after the heat wave ended, the tree canopy looked as though it had been dusted with orange snow.
New buds and needles are fragile for a number of reasons, said Christopher Still, a forest ecology professor at Oregon State University. Many contain fatty membranes that, when super-heated, will melt and cause the leaf to fall apart. Young leaves and needles also lack “heat hardening” mechanisms like specialized proteins that stabilize mature leaves and needles when it’s hot.
Many larger, more well-established trees, such as Douglas fir, lost a growing season: Their needles fell off, but grew back the following year. Other trees died, especially younger ones and species like Sitka spruce and western red cedar that require cooler, wetter temperatures.
The 2021 heat wave also rapidly dried grasses, flowers and other fine fuels, leading to record-breaking wildfires in the Pacific Northwest, according to a 2024 paper in the journal Nature.
WHILE THE TIMING of this year’s heat wave surprised many climatologists, the fact that it arrived in March may have ultimately saved some Southwestern plants, said Osvaldo Sala, a professor and director of Arizona State University’s Global Drylands Center.
During the hottest period, he explained, many plants were still dormant. Desert plants tie their growing cycles to rain and moisture instead of heat or sun duration. That means that, unlike in places like Wyoming, where cherry trees started blooming in March instead of May, desert plants were still waiting for rains to come.
Unfortunately, that early blooming has left the cherry trees and other flowering plants particularly susceptible to spring frosts, Still said.
The effects of this year’s heat dome have only exacerbated the winter’s record-setting heat and drought, Still added. Snowpack across much of the West was abysmal; in many places, it was the worst in recorded history.
“The heat dome put an exclamation point on the worst winter in a century,” said Still. “It was the worst possible way to end the winter that was already worse than normal.”
Arizona is preparing for a legal battle over its rights to Colorado River water.
Following an extraordinarily dry winter along the river basin and what’s expected to be an exceptionally hot and dry spring across the West, where high temperatures in March have already blown past records, the pressure to maintain access to the state’s fair share of river water is growing.
The Colorado River is a vital source of drinking water for 40 million people in the seven basin states, Mexico and 30 Native American tribes, and provides water for farming operations and hydroelectricity.
Reaching a water usage agreement is imperative to the basin states as the river’s water supply continues to decline, as it has done for the past 25 years due to a persistent drought spurred on by climate change.
On Monday, the Arizona Governor’s Office announced that it had retained the law firm Sullivan & Cromwell to represent the state in possible litigation among the Colorado River Basin states and the federal government.
Sullivan & Cromwell is an international firm based in New York City that has represented big names like Microsoft, BP, Goldman Sachs and JPMorgan Chase. The state is using some of the $3 million it put into its Colorado River legal defense fund last year to retain the law firm.
The Governor’s Office doesn’t expect to take any legal action until June at the earliest, but wants to be prepared for the possibility, especially if the dispute ends up before the U.S. Supreme Court.
The Lower Basin states — Arizona, Nevada and California — and the Upper Basin states — Colorado, New Mexico, Utah, and Wyoming — have been negotiating an updated water usage agreement for more than two years.
But so far the states have blown past two deadlines to do so — one in November and one in February — and are quickly approaching October, when the existing usage agreement expires.
If the states can’t reach an agreement before that, the federal government will implement one of its draft plans, all of which would place an outsized burden on the Grand Canyon State.
That’s because the Central Arizona Project, a series of canals that supplies Colorado River water to the Valley and the Tucson area, is one of the newest users of the river water, making it legally one of the first to be cut.
But so far, the Upper Basin states have refused to agree to any federally mandated water usage cuts of their own. While the Lower Basin states insist that every state take their fair share, Upper Basin states have argued that they’ve never used their full allotment and already face regular cuts and shortages based on physical availability of water.
Arizona has offered to reduce its Colorado River allocation by 27%, California by 10%, and Nevada by nearly 17%.
Negotiators for Arizona also insist that the Upper Basin states be held to the original 1922 Colorado River Compact that requires them to release a 10-year rolling average of at least 75 million acre-feet of water to the Lower Basin, in addition to one-half of the annual allotment owed to Mexico, for a total of about 80.2 million acre-feet.
An acre-foot of water represents enough to cover an acre of land to a depth of one foot, or about 325,851 gallons. That’s enough to provide three homes in Arizona a year of water, on average.
So far, the Upper Basin states have held to the original release agreement. But as water levels in the two major reservoirs on the river, Lake Mead and Lake Powell, continue to decline, it’s expected that the Upper Basin states will be unable to meet that requirement as early as 2027.
When the states entered into the original Colorado River Compact in 1922, they allocated 7.5 million acre-feet of water each year to be shared by the Upper Basin states and another 7.5 million to be used among the Lower Basin states.
Since then, the states have updated their water usage guidelines several times, even though the apportionments remain the same. But Lower Basin states face cuts mandated by the federal government during times of drought and Upper Basin states do not. In 2025, for the fifth year in a row, the federal government imposed drought-based cuts, and Arizona’s amounted to a loss of 512,000 acre-feet of water for the year.
Under current allocations, Arizona has rights to 2.8 million acre feet of water per year, and has implemented 800,000 acre feet in reductions per year. In contrast, Colorado has rights to 3.8 million acre feet a year, although it uses an average of 1.9 million acre feet, annually.
However, Colorado doesn’t always get that full allotment, because it relies mostly on melted snowpack for its water, which varies from year to year. This year’s snowpack levels are historically low, forcing water providers in the Upper Basin to place restrictions on usage based on availability and state law.
Upper Basin states argue that they regularly deal with annual shortages based on physical availability and the state laws that govern how the Upper Basin water is shared, with average annual shortages of about 1.3 million acre feet.
The Lower Basin states have undertaken significant conservation efforts for Colorado River water since 2014 and have reduced their consumption from 7.4 million acre-feet in 2015 to just over 6 million in 2024.
The Upper Basin states have increased their usage in the past five years, from 3.9 million acre-feet in 2021 to 4.4 million in 2024. The federal government’s draft plans allow for the Upper Basin states to use even more water.
Gov. Katie Hobbs’s proposed budget for this year would put another $1 million toward the Colorado River Legal Defense fund, and lawmakers earlier this month gave preliminary approval to doing just that.
Even as Arizona prepares for a legal battle, the state plans to continue attempting to reach an agreement with the other river basin states, according to the Governor’s Office.
“Governor Hobbs is committed to working with the federal government and other Colorado River states to deliver a negotiated settlement that protects Arizona’s fair share of water and stabilizes the system,” spokesman for Hobbs Christian Slater said. “However, it’s critical that Arizona be prepared to defend ourselves in court if an agreement cannot be reached or the Law of the River is violated.”

Key Points
The idea of building a pipeline to move water from eastern states to the dry West is frequently proposed to solve water shortages.
Experts argue a cross-country pipeline is technically feasible but prohibitively expensive, legally complex and environmentally risky.
Many officials and environmentalists believe more practical solutions involve local conservation, water storage and regional management.
…Kyle Roerink, executive director of the Great Basin Water Network, an organization that works to promote water conservation in the West and has opposed several water pipeline projects, says that “exporting water from the Mississippi Delta will never be a sensible or reasonable solution.” His list of explanations include the “astronomical cost” stemming from eminent domain, permitting, construction, energy management and staffing fees, and the intractability of managing healthful water quality over such vast distances with so many pollution inputs…The southeastern states may also not be as eager to get rid of their water as Arizonans might assume. Coastal erosion due to climate-worsened hurricanes, drilling and other factors mean the Mississippi Delta needs all the sediment transported downstream by its major rivers. The Mississippi’s flows play a role, too, in diluting agricultural chemicals causing hypoxic dead zones in the Gulf as the region navigates its own experiences with unpredictable drought. On top of these broad limitations — which entities across the aisle including the Goldwater Institute, a conservative policy think tank, have deemed “cost prohibitive” as well as practically and environmentally infeasible — there are complex legal water rights obstacles that likely run deeper than the Trump administration’s ability to override.
“The issue of water rights management would be a Byzantine nightmare for such a large scale project,” Roerink told The Republic. “The Mississippi isn’t adjudicated under one set of laws. It is governed under many doctrines in many states. Just as in the West, eastern states have differing state laws governing water allocations in their respective jurisdictions. There are mixes of riparian and appropriation doctrines governing use. The legal framework leads me to believe that the only thing this pipeline would be good for are lawyers who practice in the U.S. Supreme Court.”
[…]
None of this has stopped Arizona leaders, as reader Lisa Nelson asked about, from formally considering cross-country water pipeline proposals. In 2021, the Arizona Legislature voted to appropriate $160 million into a fund to consider importing water from as far as the Mississippi River. In late 2024, Chuck Podolak, director of the Water Infrastructure Finance Authority of Arizona told KUNC’s Alex Hager that the idea still deserves “serious attention.”
“We’re seeing things never seen before, in all the records that we’ve kept in the last 100 plus years,” Jones said. “I mean, we’ve not seen that here in the valley.”
He believes they’ve already seen high flows in the river back in March, when it usually happens in June. The city of Clifton primarily gets its water from the Colorado River, either pumped directly from the stream or fed through Grand Valley Irrigation. If the irrigation system runs out of water, Jones said residents may turn to treated drinking water for their lawns, which could put constraints on treatment plants.
“Our treatment plants can’t handle that demand if everybody starts wanting to water their lawns with our water,” he said.
In the Colorado River Basin, water year 2026 will go down in history…while also deepening the present crisis and casting a harsh light on the challenges of the future.
After yet another much drier- and warmer-than-normal month, NOAA CBRFC’s latest (May 1st) official 50% exceedance forecast for Lake Powell April-July inflows slid down to 800 KAF–an are-you-kidding-me 13% of average.
On my spaghetti plot for the past 36 years of Powell forecasted and observed inflows, the 2026 ‘most-probable’ forecast is now below the record-low volume in 2002 (963 KAF). It’s also below the April 1st 2026 70% exceedance forecast (950 KAF) that I said last month we should entertain as a more likely outcome, given the propensity and outlook for dry weather this spring.
If there’s any shine to put on this absolute turd of a water year, it’s that thanks to the extreme rain event in mid-October focused on the San Juan basin, and the early snowmelt, Lake Powell got 2200 KAF of inflow between October 1st and April 1st. That’s below normal, but not nearly as far below as the April-July flow will be.
And in the month of April, Powell got 366 KAF of inflow, which sets the absolute floor for the total April-July inflow volume–that is, the May 1st 50% forecast of 800 KAF includes that April inflow of 366 KAF. (As of May 5th, the observed inflow since April 1st is up to 403 KAF.)
So 2026 will end up as a very “front-loaded” water year, with most of the flow occurring outside of the April-July peak-runoff period, which typically accounts for ~80% of the water-year total. But even with that boost from the October storms, 2026 will end up rivaling, if not exceeding, 1977 and 2002 as the driest-ever water year.

May 5, 2026
The federal government has agreed to pump more than $450 million into programs to carry out additional Colorado River water conservation, Arizona Department of Water Resources chief Tom Buschatzke said Monday. The spending is necessary to make the new proposal from Arizona, Nevada and California work, Buschatzke and other water officials said Friday in releasing their offer to save 700,000 to 1 million acre-feet of river water through 2028. A million acre-feet is the equivalent of approximately 10 years’ worth of Colorado River deliveries to Tucson Water. The U.S. Interior Department proposed that the money be spent, and the U.S. Office of Management and Budget, which must sign off on all federal expenditures, approved it, Buschatze said at a news briefing Monday afternoon on the new plan from the three Lower Colorado River Basin states…J.B. Hamby, California’s Colorado River commissioner, said later Monday that what Buschatzke said is also his understanding of the federal government’s position. The federal funding offer would require the Lower Basin states to engage in a cost-sharing effort to contribute money to the water-saving scheme, Buschatzke said.
Widespread soaking rains fell across Texas and the Deep South, bringing a much needed moisture boost to these drought stricken areas. While sufficient to ease drought conditions across portions of Texas, the lower Mississippi Valley, and the Tennessee Valley, drought conditions remained mostly unchanged across southeastern Alabama, Georgia and northwestern Florida, where soil moisture and streamflows remain extremely low. Lighter rainfall also overspread the Northeast, which, combined with cooler temperatures helped slow the advancement of drought, and improved drought conditions in Maine. Where lighter accumulations occurred, there was slight expansion of drought and abnormal dryness across portions of the mid-Atlantic, Hudson Valley, and southeastern New England. Cooler temperatures and mostly dry weather overspread the Plains and Midwest. While drought conditions continued to expand across the Plains, the drier weather was mostly welcome across the upper Midwest and Corn Belt, allowing fieldwork to progress. Hot, dry weather promoted degradation across Arizona and northwestern Washington, while late season moisture across northern California did little to change the meager snowpack conditions…
Light to moderate precipitation overspread much of the High Plains, with the heaviest accumulations (0.5 – 1.5 inch) falling across central Colorado, including late season snow across the higher elevations. This precipitation resulted in some drought reduction across central Colorado. Across the rest of the Plains, however, the moisture was not sufficient to engender substantive improvements. Despite cooler temperatures lowering evapotranspiration rates, some degradation occurred across Kansas and Nebraska, and far western North Dakota…

Outside of northern California, where late season moisture provided a boost to short-term streamflows and soil moisture but did little to change the unusually low snow cover across the northern Sierras, seasonably dry weather overspread most of the West. Recent moisture eased drought conditions across far western Montana. While little change to the drought depiction occurred across the West, hot, dry conditions exacerbated impacts across Arizona, resulting in some substantial degradation. Short term dryness also increased across northwestern Washington, resulting in expansion of D0.
Following last week’s beneficial rainfall, additional rain overspread much of Texas and Louisiana over the last several days, sparking additional drought reductions. Rainfall across central and western Texas eased drought across the upper Rio Grande Valley as well. Despite the beneficial rainfall, widespread severe to exceptional drought continues across the South Region, and it will take a sustained series of heavy precipitation events to begin any widespread easing of impacts. The beneficial rainfall missed the Texas Panhandle and western Oklahoma, where poor conditions continue to affect rangeland and winter wheat. Drought conditions also expanded across Arkansas…
Looking Ahead
During the next 7 days, an active pattern is favored to continue across the Southeast, with heavy rainfall (2 – 7 inches) possible along a swath from eastern Texas through southern Alabama. These rains would continue to bring drought relief and also a threat of severe weather. Lesser accumulations are favored across Georgia and Florida, which may limit the extent of any improvements. Widespread precipitation is also favored along the Ohio Valley and across the eastern seaboard, with the greatest potential for relief across the Northeast. Somewhat drier conditions across the mid-Atlantic may limit the potential for drought improvement. Light accumulations forecast across the Plains may do little to ease drought conditions, while another week of seasonable dryness is forecast across the West. Above-average temperatures across the West favor an acceleration of snowmelt, which may bring short term reservoir boosts but leaves the water supply even more short as summer approaches. Below-average temperatures are favored for the eastern half of the CONUS.
During the 8-14 day period, above-average temperatures are favored for much of the lower-48, with near normal temperatures forecast for the Northeast. Above-average precipitation is forecast for the southern tier, with the highest probabilities across Texas, eastern New Mexico, and Louisiana. A slight tilt towards above-normal precipitation extends across the Great Lakes Region into the Northeast, while below-average precipitation is favored for the northern Rockies.

The Colorado Basin River Forecast Center (CBRFC) geographic forecast area includes the Upper Colorado River Basin (UCRB), Lower Colorado River Basin (LCRB), and Eastern Great Basin (GB).
Water Supply Forecasts
April-July volume forecasts are well below normal and rank in the driest five on record at many locations. Record low snowpack and poor soil moisture conditions are the primary hydrologic conditions impacting the water supply outlook, while future weather is a primary source of forecast uncertainty. May 1 water supply forecasts are summarized in the figure and table below.
May 1, 2026 seasonal water supply forecast summary.
Water Year Weather
The 2025–26 meteorological winter (December–Februrary) was the warmest winter on record for vast swaths of the CBRFC area. It was the driest March on record at numerous SNOTEL sites across the CBRFC area, and an unprecedented heatwave during the last half of March led to significant snowmelt. April weather was cooler and wetter compared to March, with most areas receiving near normal April precipitation. The figures and table below summarize water year 2026 precipitation.
Water year 2026 precipitation summary.
Snowpack Conditions
Snow water equivalent (SWE) has been tracking at or below record low for the past several months. The significant heatwave during the last half of March led to historically low April 1 snow water equivalent conditions across the region. An early April NRCS-Utah Snow Survey Special Report stated that “at no time since systematic snowpack measurements began around 1930 has April 1 snowpack been this low in the state of Utah, and 2026 SWE is roughly five times lower than the previous record low” . A similar analysis performed in early April by the Colorado Climate Center concluded that “this has been the worst year for Colorado snowpack in recorded history, and most locations have less than half of the previous record low”
Precipitation during April led to modest snow accumulation and reduced snowmelt rates due to cooler and cloudier weather. However, May 1 SWE remains at record low values at many SNOTEL stations across UT, WY, and CO. May 1 SWE across the UCRB and GB is generally less than 30% of normal and below the 10th percentile. SWE conditions are more favorable, but still well below normal across northern areas including the headwaters of the Upper Green and the Bear River Basin. SWE conditions are summarized in the figure and table below.
Left: May 1, 2026 SWE – NRCS SNOTEL observed (squares) and CBRFC hydrologic model. Right: CBRFC hydrologic model SWE conditions summary.
Soil Moisture
CBRFC hydrologic model soil moisture conditions impact water supply forecasts. Basins with above average soil moisture conditions can be expected to experience more efficient runoff from rainfall or snowmelt while basins with below average soil moisture conditions can be expected to have lower runoff efficiency until soil moisture deficits are fulfilled. The timing and magnitude of spring runoff is impacted by snowpack conditions, spring weather, and soil moisture conditions.
Mid-November 2025 soil moisture conditions were below normal across most areas as a result of warmer and drier than normal weather during the 2025 water year. Higher elevation soil moisture/baseflow conditions typically don’t change much during winter months as snow is accumulating. However, this has not been the case this season. Early April CBRFC model soil moisture conditions were generally above average due to snow melt that occurred during the late March heatwave. Early May soil moisture conditions are generally below average across lower elevations, with near average soil moisture conditions across higher elevations. CBRFC hydrologic model soil moisture conditions are shown in the figures below.

Upcoming Weather
Weather during the first week of May has been unsettled across the CBRFC area, including a significant winter storm across the mountains of Wyoming and Colorado. Warmer and drier conditions will develop in the coming days. The 7-day precipitation forecast and the Climate Prediction Center (CPC) 8–14 day temperature and precipitation outlooks are shown in the figures below.

Every six months or so I like to do a recon of the Lisbon Valley in southeastern Utah, a long-time sacrifice zone for uranium and copper mining, oil and gas drilling, natural gas processing, and now lithium extraction — not to mention cattle grazing — to see about the latest developments. My takeaway from my latest visit: The sacrifice continues — both in a real sense and a speculative one.
The speculation is in the form of a rush to stake mining claims on nearly every inch of available public land in the valley. This phenomenon isn’t readily apparent on the ground, but showed up indirectly in the form of orange No Trespassing signs posted on public roads in one specific area. Except they aren’t really prohibiting trespassing — that would be illegal. They are just pointing out that the Lisbon Valley Mining Company has already claimed all of the public land around there, so new would-be claimants should just stay away.

Meanwhile, after shutting down in 2024 due to high costs and staffing challenges, the Lisbon Valley copper mine, which posted the signs, is back in business. Late last year Mariana Minerals, backed by the Silicon Valley venture capital firm Andreessen Horowitz, purchased the then-idled mine. Mariana’s CEO is Turner Caldwell, who previously ran Tesla’s battery minerals unit. Perhaps it was his cybertruck that sat in the mine’s parking lot when I drove by recently.
At the mine’s grand reopening ceremony last month, Caldwell said he was hoping to “fundamentally reinvent how infrastructure is built, how mines are operated and how refineries are operated.” This includes using autonomous drills, equipment, and haul trucks, as well as robots to do inspections and conduct more hazardous work.
This purportedly will allow the operation to increase production from about 2,500 tons annually under the previous ownership, to a target of 50,000 tons per year by 2030 — an enormous jump. Historically, the most the mine produced was about 10,000 tons annually. But last year the BLM approved the company’s proposed expansion of its open pit operations and to add an in-situ extraction operation — a prospect that alarmed nearby residents concerned about contamination of aquifers.
Caldwell is vague about the number of jobs the revived operation will create. On the one hand, he’s said he plans on hiring “hundreds” of new workers and invest over $1 billion. On the other, the autonomous equipment’s main asset is that it alleviates past staffing difficulties. As of early May, the Mariana website advertised just 19 open jobs at the Lisbon Valley site. That includes several salaried positions, with pay ranging from $100,000 to about $180,000 per year, as well as drillers, equipment operators, and mechanics at $25 to $45 per-hour wages. Interns could earn $30/hour.
Whether any of that will be enough to afford housing in Moab or even La Sal or Monticello is unclear.
I passed through there on a Sunday, and things were quiet. One haul truck was sitting in the pit, and it appeared as if it was running but it wasn’t doing any hauling. I couldn’t get close enough to confirm that there was no human driver, but the cab did look empty. There were no robots in sight.
Meanwhile, down in Arizona’s copper country, the Center for Biological Diversity, the San Carlos Apache Tribe, and the Lower San Pedro Watershed Alliance filed an intent to sue the Trump administration over its approval of Faraday’s Copper Creek exploratory drilling project east of Mammoth, Arizona, saying it violates the Endangered Species Act.
The exploratory project, a precursor to actual mining, includes 67 drill pads, along with associated roads and infrastructure, on about 78 square kilometers in the Galiuro Mountains in the Lower San Pedro Watershed. Each drill rig requires tens of thousands of gallons of water in an area where communities are facing water shortages and the riparian ecosystem is stressed by prolonged drought. The groups’ lawsuit focuses on the drilling’s impacts on the imperiled Mexican spotted owl and other wildlife.
“The Lower San Pedro watershed is one of Arizona’s most important wildlife corridors, and this exploration project is pushing industrial disturbance into a landscape that is already under pressure,” said Melissa Crytzer Fry, chair for the Lower San Pedro Watershed Alliance. “When agencies ignore clear evidence and fail to follow the law, local communities are left to defend the river, the habitat and the species that make this place irreplaceable.”
🐟 Colorado River Chronicles 💧
If you’re bummed out about the reduced releases from Glen Canyon Dam — and the associated drop in streamflows in the Grand Canyon — you might try going upstream a ways and boating the Green River or the Colorado River below the confluence of the two. On May 1, the Bureau of Reclamation upped releases from Flaming Gorge Dam to full power plant capacity, or 4,600 cubic feet per second. Then, on May 4, they started allowing an additional 4,000 cfs to flow through the dam’s bypass to implement a larval trigger study plan (and to bolster Lake Powell’s levels).

Today (May 5) the Bureau was releasing about 9,000 cfs from the dam. While the first pulse (the May 1 release) has made it downstream, the second one has yet to reach Ouray, Utah, if the USGS streamflow gage is any indication. But as that 9k cfs makes it downstream, it should make for some good boating — or at least better than you’d expect during such a dry year — not only on the Green, but also in Cataract Canyon. Whether it will bail out Lake Powell is another question altogether.

🗺️ Messing with Maps 🧭
A couple of weeks ago I wrote about the Trump administration’s mapping tool, aimed at making America graze again, showing “potentially available” (i.e. vacant) grazing allotments on public lands. Now the mapping folks at Center for Biological Diversity have taken that map, and overlain it with areas of endangered species’ critical habitat and BLM allotment health status. It can be a little overwhelming to navigate because of all the different layers and colors. But you can turn layers on and off to make it easier to use, and it’s valuable for just understanding the landscape in general.

This is likely no surprise to you, but drought persists across the U.S. and is intensifying in some areas. No geographic area is immune to the potential of drought at any given time. The U.S. Drought Monitor provides a weekly drought assessment, and it plays an important role in USDA programs that help farmers and ranchers recover from drought.
The Facts
Fact #1 – Numerous agencies use the Drought Monitor to inform drought-related decisions.
The map identifies areas of drought and labels them by intensity on a weekly basis. It categorizes the entire country as being in one of six levels of drought. The first two, None and Abnormally Dry (D0), are not considered to be drought. The next four describe increasing levels of drought: Moderate (D1), Severe (D2), Extreme (D3) and Exceptional (D4).
Fact #2 – U.S. Drought Monitor is made with more than precipitation data.
When you think about drought, you probably think about water, or the lack of it. Precipitation plays a major role in the creation of the Drought Monitor, but the map’s author considers numerous indicators, including drought impacts and local insight from over 450 expert observers around the country. Authors use several dozen indicators to assess drought, including precipitation, streamflow, reservoir levels, temperature and evaporative demand, soil moisture and vegetation health. Because the drought monitor depicts both short and long‐term drought conditions, the authors must look at data for multiple timeframes. The final map produced each week represents a summary of the story being told by all the pieces of data. To help tell that story, authors don’t just look at data. They converse over the course of the map-making week with experts across the country and draw information about drought impacts from media reports and private citizens.
Fact #3 – A real person, using real data, updates the map.
Each week’s map author, not a computer, processes and analyzes data to update the drought monitor. The map authors are trained meteorologists from the National Drought Mitigation Center at the University of Nebraska-Lincoln (the academic partner and website host of the Drought Monitor), the National Oceanic and Atmospheric Administration, the National Aeronautics and Space Administration, and USDA. The author’s job is to do what a computer can’t – use their expertise to reconcile the sometimes-conflicting stories told by each stream of data into a single assessment.
Fact #4 – The Drought Monitor provides a current snapshot, not a forecast.
The Drought Monitor is a “snapshot” of conditions observed during the most recent week and builds off the previous week’s map. The map is released on Thursdays and depicts conditions based on data for the week that ended the preceding Tuesday. Rain that falls on the Wednesday just before the USDM’s release won’t be reflected until the next map is published. This provides a consistent, week‐to‐week product and gives the author a window to assess the data and come up with a final map.
Fact #5 – Your input can be part of the drought-monitoring process.
State observers in the drought monitoring network relay on-the-ground information from numerous sources to the US Drought monitor author each week. That can include information that you contribute.
The Drought Monitor serves as a trigger for multiple forms of federal disaster relief for agricultural producers, and sometimes producers contact the author to suggest that drought conditions in their area are worse than what the latest drought monitor shows. When the author gets a call like that, it prompts them to look closely at all available data for that area, to see whether measurements of precipitation, temperature, soil moisture and other indicators corroborate producer-submitted reports. This is the process that authors follow whether they receive one report or one hundred reports, although reports from more points may help state officials and others know where to look for impacts.
There are multiple ways to contribute your observations:

The dusty Acequia Madre de Cañon de Chama, pictured above April 28, 2026, will soon divert Rio Chama water toward historic orchards the San Joaquín del Rio de Chama Land Grant first planted more than 200 years ago, thanks to a new agreement between the land grant and the Santa Fe National Forest.

May 5, 2026
A dusty acequia in northern New Mexico, which more than 200 years ago diverted water from the Rio Chama, will soon spring to life again, nourishing freshly planted orchards of plums, apples and apricots.
That’s the idyllic scene envisioned through a new agreement between the Santa Fe National Forest and heirs of the San Joaquín del Rio de Chama Land Grant. The parties say the “memorandum of understanding” they signed in late March marks the potential thawing of more than a century of tension between New Mexico land grants and the federal government.
The agreement, which the Santa Fe National Forest Service provided to Source NM through a public records request, identifies the acequia restoration as a “project of mutual interest.” It also recognizes the land grant as a consulting partner to the Forest Service and provides it greater input into the land’s future use.
Leonard Martinez, president of the land grant, told Source NM that the nine-page agreement is a “historic document,” one that marks the first such formal agreement between land grants and the Forest Service. He said he’s spent nearly every day since the agreement was signed clearing the historic irrigation canal and working to reconnect it to the Rio Chama.

If all goes well, he will open the headgates of the Acequia Madre de Cañon de Chama later this summer, sending Chama River water to irrigate a cover crop of alfalfa. Within five years, he hopes to replant historic orchards.
When that happens, he said, he hopes the “heirs who have left us,” many of them still buried in a cemetery near the headgates, will approve of his efforts.
“That’s the key here,” he said. “We want to put our orchards and our fields back in.”
Santa Fe National Forest spokesperson Claudia Brookshire told Source NM that the agreement resulted from trust established through informal talks and individual projects.
“The Forest Service has long been willing to work with land grants,” Brookshire said in an email. “But the lack of a formal framework, combined with trust barriers, made it difficult to begin projects on national forest system lands.”
The Santa Fe National Forest is in early discussions to develop similar agreements with two other land grants, Brookshire said.
In 1806, Spanish Governor Joaquín del Real Alencaster charged 44 families with stewardship of a 470,000-acre swath of what was then the New Mexico Territory. By 1860, according to the land grant, more than 800 residents established roots there, cultivating land within the river valleys, pasturing livestock and gathering resources from the surrounding common lands, known as the “ejido.”
But after multiple lawsuits and land re-surveys over the ensuing decades, the federal government and land speculators acquired the land and evicted the residents. By 1905, the federal government recognized only about 1,500 acres of land along the Rio Chama as belonging to the land grant, but even that parcel ended up in the hands of the Rio Arriba Land and Cattle Company.
The parcel west of Abiquíu, known as the Cañon de Chama, remained the company’s property for decades before the federal government ultimately acquired it, as well. Today, all of the original San Joaquín del Rio de Chama Land Grant belongs to the Santa Fe National Forest or Carson National Forest.
Land grant heirs like Martinez have fought for more than a century to reassert their rights over the land, including seeking Forest Service permission to visit and care for the cemetery where their ancestors are buried.
The heirs ultimately received a Forest Service easement in 2013 to access the cemetery. Since then, Martinez and other land grant leaders have continued to pressure the Forest Service for more access, particularly to the Cañon de Chama, which heirs describe as culturally and historically significant.
Martinez told Source NM that the agreement is a result of trust built through the cemetery easement, he said, as well as guidance from the New Mexico Department of Justice’s Treaty of Guadalupe Hidalgo Division.
The NMDOJ created the division in 2003 to oversee and address concerns related to the provisions of the 1848 Treaty of Guadalupe Hidalgo, which ushered in the United States’ government’s problematic land title confirmation process and stripped the San Joaquin land grant heirs of hundreds of thousands of acres of communal land.
New Mexico Rep. Miguel Garcia (D-Albuquerque) has spent much of his 30 years in office advocating for land grant heirs, including seeking recurring state funding and greater recognition of the historical injustice of the federal government’s land seizure.
While he said the new agreement represents a “great leap forward” and commended Martinez and others for their efforts, he said his ultimate goal remains for the Forest Service to return land it now controls to the land grants.”
“These land grants that lost these common lands have not ceded their right to that land,” he said. “They have not given up that hope.”
To get to the river and listen, there is an intricate web of management issues, antiquated infrastructure, and century-old legal disputes to thrash through. Unless you’ve gone outside in the Southwest lately. A 26-year drought is sucking the river dry, and unprecedented heat is rapidly evaporating this year’s record-low snowpack.
These two conditions are leading to low water levels at Lake Powell and Lake Mead, the nation’s two largest reservoirs. That, in turn, jeopardizes critical water infrastructure for a large swath of the West.
Reporting on this issue from the front lines, the growing margins of Lake Powell returning to Glen Canyon, made this reality strikingly clear. The river’s returning are only a portion of this watershed story. There are major questions about how the Colorado River will make it past Glen Canyon Dam in a rapidly drying future. Whether you love or hate Lake Powell, this is not an issue of recreation; it is about water equity for millions of people, desert ecosystems, and wildlife.
A 1,500-word story is painfully insufficient to explain the breadth of this issue that threatens an entire watershed. Writing a book is starting to feel sane! Of course, I do not make this easy for myself, always crawling around in the desert and floating around the watershed. But there is good reason to take the long view. As I write Riverside (Torrey House Press 2027), my life will continue its pulse between the river and writing flash floods. My PFD is on tight. Thanks for hopping aboard.

With such low flows, the Colorado River Basin will likely turn to pumping groundwater. The threat to springs affects the river’s baseflows, which are significantly supported by groundwater and springs.

May 1, 2026
In a Thursday joint statement, the Upper Colorado River Basin states of Colorado, Utah, New Mexico and Wyoming called for “immediate mediation” in the yearslong deadlock with the Lower Colorado River Basin states of Nevada, California and Arizona. They offered no details about who could fill that role or which entity would pay for the costs.
“Time is short, but structured negotiations through mediation offer a new path for authentic discussions,” New Mexico’s Upper Colorado River Commissioner Estevan López said in a statement. “Even at this late stage, we should pursue every opportunity to reach a workable agreement.”
[…]
Asked about how a mediator could differ from the federal government’s intervention or the appointment of a so-called “water master” at the U.S. Supreme Court, Entsminger said states are unlikely to view a mediator’s decision-making as binding.
“It’s certainly not litigation; it’s not even arbitration,” Entsminger said. “It’s more of a marriage counselor.”
[…]
Colorado River Board of California Chairman JB Hamby said in a Tuesday statement that his state proposed a mediation process last year. California officials see the need for both long- and short-term solutions, and mediation could push the Upper Basin toward “verifiable water contributions,” Hamby added.
“Effective mediation requires common ground, and the system cannot wait,” Hamby said. “Current conditions require immediate, measurable water reductions from every state.”

Frisco’s town manager can now implement water conservation measures outside of the standard triggers outlined in the town’s water code after an ordinance under consideration officially passed. Frisco Town Council approved Ordinance 26-10 on first reading at its April 14 meeting and adopted it on second reading at its April 28 meeting. The ordinance amends Article V of Chapter 171 in the town code to add the ability for the town to implement levels of its water restrictions if it’s determined that “significantly below-average snowpack” or “significantly above average temperatures” or a combination of these factors, both existing or anticipated, pose a risk to the town’s ability to provide water.
Prior to the amendment, the code used certain streamflow and water well storage levels to trigger levels of the water restrictions…A town meeting recap stated that “as of March 31, the North Ten Mile Creek watershed, which provides Frisco with much of its water,” had only roughly 7.3 inches of snow-water equivalent, which is about half as much liquid water stored in the snow compared to the five-year average.
“The 2025–2026 winter season produced historically low snowfall across the Rocky Mountain region, resulting in well-below-average snowpack levels that are critical to the Town of Frisco’s municipal water supply. Above-average spring temperatures have further exacerbated these conditions by accelerating snowmelt, increasing evapotranspiration, and driving higher wildfire conditions. These combined factors are significantly reducing available water supply at a time when seasonal demand will be increasing the Town’s daily water production by over 100%. Dillon Reservoir remains below historical storage levels, underscoring the vulnerability of the Town’s water resources and providing a real time visual reminder of just how limited the local hydrologic cycle is this year.”
Due to the historically low snowfall, which has led to the most severe drought designation by the U.S. Drought Monitor, town staff recommended moving from the current Phase 1 voluntary measures to Phase 3 mandatory restrictions, which limits “non-essential outdoor irrigation to two days per week in addition to other restrictions,” according to the town recap. Staff explained it’s possible that North Ten Mile Creek may run dry due to the current conditions and forecasts, which would require the town to rely on its wells, “which have been resilient even when the reservoir has been very low.”
The Bureau of Reclamation has adjusted the release schedule from Navajo Dam due to downstream maintenance activities. On Tuesday, May 5th at 4:00 AM, the release will increase from 450 to 500 cubic feet per second (cfs). A further increase to 550 cfs is planned for Thursday, May 7th at 4:00 AM.
Releases are made for the authorized purposes of the Navajo Unit, and to attempt to maintain a target base flow through the endangered fish critical habitat reach of the San Juan River (Farmington to Lake Powell). The San Juan River Basin Recovery Implementation Program recommends a target base flow of between 500 cfs and 1,000 cfs through the critical habitat area. The target base flow is calculated as the weekly average of gaged flows throughout the critical habitat area from Farmington to Lake Powell.
This scheduled release change is subject to changes in river flows and weather conditions. If you have any questions, please contact Conor Felletter (cfelletter@usbr.gov or 970-637-1985), or visit Reclamation’s Navajo Dam website at https://www.usbr.gov/uc/water/crsp/cs/nvd.html

With drought and high temperatures putting unprecedented pressure on water users throughout Colorado, from cities to agriculture, there’s one segment that can be affected first — and maybe worst — when it comes to a lack of water: rivers themselves and the ecosystems that depend on them.
As cities enact water restrictions and farmers and ranchers prepare for the worst, impacts of the water shortage are readily apparent in a chronically dry stretch of the Colorado River between Palisade and the confluence of the Gunnison River that is critical habitat for endangered fish, known as the 15-mile reach.
The Upper Colorado River Endangered Fish Recovery Program works to return water to this stretch of river in the Grand Valley, but because of this year’s historically dry conditions, the program could have only 16,000 acre-feet, half its typical amount of water for fish.
Beyond that guaranteed amount, the program mostly uses water-sharing agreements that can secure additional acre-feet to boost flows — but only when other users don’t need the water and can voluntarily loan it. This year finds nearly everyone who depends on the Colorado River and its tributaries in dire straits.

There won’t be any surplus water for fish in the Historic Users Pool, which is stored in Green Mountain Reservoir and is the largest source of water to potentially augment fish flows. A pool of water in Ruedi Reservoir that is available in four out of five years isn’t there, and the program could get only about 340 acre-feet from a pool in Wolford Reservoir upstream of Kremmling that typically has up to 6,000 acre-feet.
“It is really clear to me that we do not have enough tools in our toolbox to be able to manage for conditions like we have this year in the 15-mile reach,” said Julie Stahli, recovery program director. “We are so far outside the bounds of what we have ever seen before, that it’s really just hard to be able to make any good decisions.”
Stahli said she anticipates the program can contribute about 75 cubic feet per second through mid-July, at which point they will drop it down to 50 cfs, a bare-bones amount that is just enough to keep the riverbed wet.

“That is what we are anticipating being able to have for the entirety of the season in the 15-mile reach,” she said.

As flows plummet, fish could become stranded in pools that are disconnected from the rest of the river, and program managers say they will try to prevent fish from using that stretch of river during times when flows are predicted to be at their lowest. Crews could use netting to keep fish out of the reach or close the flow of water that returns fish to the river after they accidentally enter an irrigation canal, which would keep them in the stretch of river above the diversion that has more water.
“Our main goal at this point is just to keep fish out of that reach,” Stahli said. “There is not a whole lot of attractive habitat in there right now for fish. Flows dropped so early in the season. We’re already seeing some pretty dire conditions in April.”
For several days in April, flows fell to just over 50 cfs, among the lowest levels in recorded history and far below the recovery program’s target flow for April in a dry year of 1,240 cfs. According to Stahli, the river’s flow at that low point could be solely attributed to recovery-program water that it had released from upstream reservoirs.
The goal of the recovery program when it was created in 1988 was to protect the humpback chub, razorback sucker, bonytail and Colorado pikeminnow, while also allowing the seemingly opposing goal of developing more water. An aim of the program was to allow farms and cities to continue using water and even expand their use without violating the Endangered Species Act.

And the program has had some success, with one of the four species — the humpback chub — being downlisted from endangered to threatened in 2021. (The U.S. Fish and Wildlife Service has also proposed downlisting the razorback sucker.) These fish evolved over millions of years and are only found in the Colorado River basin. In today’s highly engineered and managed river ecosystem, they live mostly in just a few key locations in the Upper Basin, including the 15-mile reach, and in parts of the Yampa and Green rivers. Grand Junction’s minor league baseball team has adopted the charismatic fish as its team name and mascot; last year it was the humpback chubs, and now it’s the razorback suckers.
But the program has had trouble meeting target minimum flows in the 15-mile reach, even though upstream water development has not kept pace the way it was expected to. A main culprit is climate change, which has robbed the river of about 20% of its flows during the 21stcentury.
“We just don’t have the tools as a society to be able to handle what’s happening right now in any cohesive way,” Stahli said. “This isn’t an endangered fish problem; this is an everyone problem.”

Why is the river dry?
The reach is just downstream of large Grand Valley agricultural diversions, which are used to grow crops such as corn, alfalfa and the famous Palisade peaches, and which can take a combined 1,950 cfs from the river. At certain times of year, there can be more water in the Grand Valley’s canals than there is in the nearby Colorado River. Collectively, they are the biggest agricultural diversion from the Colorado River on the Western Slope.
“There has been so much diversion and damming of the river farther upstream,” said Bart Miller, healthy rivers director at environmental group Western Resource Advocates. “There are a lot of uses right there, and you’re seeing the impacts of all the Front Range diversions. [The 15-mile reach] is a pinch point in the system based on all the water development we’ve done.”
Water rights for the environment and recreation were latecomers to the legal system. It wasn’t until the 1970s — nearly 100 years after the most-senior agricultural rights on the Western Slope were established — that Colorado began protecting the value of water in streams with its instream flow program. Under Colorado’s system of water law, those who use water by taking it out of the river — including farmers, cities and industry — usually have the oldest rights, giving them first use of the resource. There’s nothing illegal about drying up a river.
“It’s like you’re running in a race and it’s four laps around the track,” Miller said. “The folks with the instream, recreational, environmental values are there at the starting line, but they’re held back for the first two or three laps. Everyone else is already running. And that’s why the environment often ends up in a really bad place.”

‘April hole’?
It’s not totally unheard of to have a small window of diminished streamflows in April. In a phenomenon known as the “April hole,” irrigation demands in the Grand Valley ramp up, while the needed water remains frozen solid as high-country snowpack. This problem remedies itself within a couple weeks as the snow begins melting. But this year, little snowpack remained by April and water managers think spring runoff at Cameo, where the big Grand Valley diversions are located, peaked during the March heatwave.
Kate Ryan is executive director of the Colorado Water Trust, which works to put water back into streams through temporary water sharing agreements with agricultural, municipal and industrial water users. Although the Water Trust is still finalizing contracts for this year, Ryan said she expects the Water Trust to add about 4,700 acre-feet of water to the 15-mile reach by leasing water from Ruedi Reservoir owned by the town of Palisade, and oil-and-gas company QB Energy.
In past years, water from this project has been released between the end of July and beginning of October. But that timing may change if the recovery program is trying to keep fish out of the reach.
“We will make sure that we deliver water at a point that complements the work of the recovery program,” Ryan said.
The Water Trust has also used the Colorado River Water Conservation District’s water marketing program — where acre-feet are available for purchase — to restore water to streams. But the River District board at its April meeting voted to freeze all new contracts, which are usually doled out first come, first served, while staff figures out the best use of the limited water supply.
The move was part of a series of drought mitigation actions aimed at easing shortages for water users. The board last month also approved a system for prioritizing water sectors, with keeping water in rivers at the bottom of the list: municipal and domestic water needs over agricultural and industrial needs; and agricultural and industrial needs over in-channel uses such as those that benefit the environment, endangered fish and recreation.
The Water Trust this week sent a letter to some water managers recognizing the historic drought and acknowledging that many of its temporary water sharing agreements, which pay water rights holders to leave water in streams, may not operate this year because their agricultural partners may not have enough water for their own use. Projects are voluntary and happen only in years when participants have enough water to share and it can benefit a stream.
But the letter also said there may be others who are interested in using their water rights to help prop up a stream this year.
“There is just so much uncertainty right now that we are trying to be as flexible and responsive as possible,” Ryan said.

Recovery-program officials said this year they will double down on other actions that benefit endangered fish, including removing nonnative predator species such as smallmouth bass and stocking the river with hatchery-raised fish. On Friday, students at Palisade High School released 1,500 young razorback suckers and bonytails that they helped raise into the Colorado River at Riverbend Park in Palisade.
Recovery-program staff said managing the 15-mile reach this year is about preventing the worst impacts and seeing what lessons can be learned from one of the driest years on record.
“It is just new terrain,” said David Graf, instream flow coordinator for the recovery program. “I think we are just flying by the seat of our pants in a lot of ways trying to do triage management as opposed to really adapt.”
For now, one of the few ways to add water back to a depleted river remains borrowing it from other, more senior users.
“I think until our water suppliers and state government hear from people that the environment really is a priority, not just the recovery program and need to support endangered species, but also for communities and local economies across the board, it’s going to stay that way,” Ryan said.

If someone were to be dropped from another planet into the North Fork Valley in western Colorado today, they would be forgiven for assuming there is not a water crisis. A thick carpet of green covers the valley floor, the irrigation canals are filled to the brim, trees are leafing out, the river is running and Paonia Reservoir is almost full, and the mountains are still graced with snow.
I didn’t even come from outer space — I think — and I find the contrast between the news reports of water shortages and restrictions and the on-the-ground situation here to be quite jarring. Is it possible that April precipitation has averted the calamity?

Yes, a series of storms, some quite abundant, have moved through the Upper Colorado River Basin, boosting snowpack and soothing the desiccated earth. It has certainly felt cooler and wetter than normal, but that was mostly an illusion brought on by the abnormally dry winter and the searing March heatwave. And it hasn’t been nearly enough to offset the warm winter and the lack of snow, as the graphs below indicate.
As for the full ditches, I guess you could attribute that to a “make hay while the water is available” sort of ethos. You might as well douse the fields and fill ponds while spring runoff is in full swing and the river still runs, knowing that it may not last beyond June. Meanwhile, Paonia Reservoir’s relatively healthy levels are the result of the Fire Mountain irrigation canal — which relies on reservoir water — being shut down for emergency repairs.
Meanwhile, there is a conspicuous absence here in this agricultural hotspot: There are no blossoms or fruit on apple, cherry, peach, or pear trees. The March heatwave sparked a spectacular orchard super-bloom. That was followed by a devastating freeze that killed all of the fruit, even in orchards where extreme preventative measures were taken, and even “burned” the leaves on some trees. Wacky weather indeed.

🐟 Colorado River Chronicles 💧
Phil Lyman, the former and hopeful Utah politician, recently posted this on Facebook:
Just to sum it up: He’s knocking a federal program that pays willing farmers to voluntarily cut off irrigation to their fields in order to conserve water in an effort to balance Colorado River demand with the shrinking supplies. And he’s blaming it all on California.
Lyman’s general sentiment is not new, nor is it uncommon among water users in the Upper Basin states. In fact, it’s basically a cliché. Since I was a kid I’ve heard folks saying something along the lines of: If we don’t use the water, it’ll just run on down to California, where those L.A. folks will guzzle it up to fill their swimming pools and water their golf courses. It’s a rather simplistic view, and one that doesn’t account for the realities of water law or the way the Colorado River system works. In other words, it’s just plain wrong, and a candidate for Congress — as Lyman is — should know better.

The Colorado River and its users have a problem: Demand for the water exceeds supply, and the supply is continually shrinking. Since boosting supply is not a feasible option, demand — i.e. consumptive use — must be reduced significantly. While everyone must make cuts, agriculture is the river’s largest water user by far, meaning that sector is going to have to make the largest cuts, by volume. This isn’t about demonizing farmers or alfalfa, it’s not about whether Californians or Utahns are more deserving of the water. It’s simple math.
The farm fallowing program is one way to cut consumption quickly by paying willing farmers to voluntarily forego irrigating some or all of their fields on a year-by-year basis. It’s not ideal, but it is legal, voluntary, and can save junior water rights holders, including cities and towns throughout the watershed, from being forced to shut off their water intakes. And in no way is farm fallowing exclusive to Utah. It’s occurring all over the place.
Let’s do a little fact-check of Lyman’s other points:
Farm fallowing in Utah is being done to benefit California, which “demolished its water storage infrastructure.” No and no. The goal here is to leave a little more water in the river, to keep the whole system from collapsing. Any amount conserved in one place will potentially benefit all other river users, as well as the river itself. Foregoing irrigation on a Utah farm, for example, could help keep the taps on in St. George or some other Utah community that relies on the river. Dams have been removed in California, most significantly four structures on the Lower Klamath River. But those were primarily for hydropower production, not irrigation or water storage, and they are far removed from the Colorado River or any associated water storage.
“Paying farmers not to feed us to bail out California’s failures …” Actually, the feds and state and other programs mostly are paying farmers not to grow alfalfa or hay, which feed cattle, and it has nothing to do with California’s “failures.” Indeed, California grows a lot of alfalfa, too, but it also grows all kinds of vegetables — far more than in Utah.
If the water saved in Utah does make it to the Lower Basin and California, then the biggest beneficiary would be … farmers. Most of the water in the Lower Basin goes to the Imperial Irrigation District, where it is used for farming. Those farmers have also been part of the federal fallowing program, and have managed collectively to reduced their Colorado River water consumption by about nearly 1 million acre-feet since 2003.
Lyman calls for eliminating or restructuring federal farm fallowing programs. I’m curious if he’s talked to the farmers about this, especially the ones who may lose their water and be forced to fallow anyway. Isn’t it better to get paid not to grow something than to not get paid for it?
“… fight to end federal policies that separate water from the people who depend on it. Water rights are property rights.” We all depend on water; the California farmers depend on water just as much as Utah farmers do. Furthermore, the California farmers also own their land, they have some of the most senior water rights on the Colorado River, and according to the “Law of the River,” they could likely go to court to force many Utah farmers to stop irrigating altogether, without compensation. The farm fallowing program does not separate water from the farmers, it simply pays them to temporarily forego irrigation.
“… end the war on farm water.” Look, there is not enough water in the Colorado River for everyone. Everyone will have to take cuts, but irrigated agriculture is the biggest user by far, and therefore will have to make cuts in order to balance supply and demand. It’s simple math: All of Las Vegas and southern Nevada use less than one-tenth of the water that goes to the farms in the Imperial Irrigation District.
“… propose that the federal government build and operate desalination plants in California to free up Colorado River water for Utah …” Desalination will likely be a part of the West’s water future, especially for coastal urban areas. But building the plants, and processing and transporting these kinds of volumes of water, would be outrageously expensive and energy-intensive, which would be especially harmful to farmers, who rely on cheap water.

The Bureau of Reclamation recently decreased Glen Canyon Dam releases from about 8,200 cfs to a steady 7,000 cfs (without the usual nighttime reductions). This appears to be the lowest sustained releases since the dam was built, and if continued throughout the entire year would lead to only 5 million acre-feet of annual releases, which would make the Lower Basin states even more grumpy and litigation-happy than they already are.
But not to worry, the feds are still on course to release 6 MAF for the water year, because they released about 10,000 cfs during January and February. Still, it’s going to change the complexion of rafting in the Grand Canyon, for sure, and it is certainly pushing the boundaries of the Grand Canyon Protection Act.

The Colorado Water Conservation Board is funneling $40 million to dozens of water projects statewide as communities grapple with a drought emergency that is making saving water more important than ever before.
Among the 136 projects receiving state support this fiscal year, which ends June 30, is a $2.3 million grant that will pay nearly half the cost to install new, automated irrigation control systems across 105 Denver Public School system sites. Another grant, for $227,225, will help the city of Trinidad with early studies on repairing and potentially enlarging Monument Lake Reservoir.

Still another grant, for $111,855, will help pay to train and certify metro area teens in becoming turf replacement specialists. Operated by the Neighborhood Resilience Corps, the initiative will replace 23,000 acres of grass at sites that include the Governor’s Mansion and other state facilities.
The grant awards come as Colorado faces a stunning drought year in which winter mountain snows were historically low and a spring heat wave melted those snows early, slashing water available for cities, industries and farms to use.
Aurora, for instance, is expecting just 10% of its normal water supplies this year, according to Tim York, manager of water conservation for Aurora Water, and its reservoirs stand at 57% full.
As cities broadcast the need to cut back water use to preserve water stored in reservoirs, homeowners and businesses have flooded cities like Aurora with requests for help to design drought-proof landscapes and replace thirsty bluegrasses with lawns that need much less water.
“Our approved applications have doubled over what they were last year, so that is pretty good,” York said, referring to applications for Aurora’s landscape conversion program. “Our free design program is similar. We have a waitlist.”
He said the CWCB grants, coupled with Aurora’s aggressive water conservation initiatives, are critical to helping the state cope with the drought emergency and create more sustainable water systems.
Aurora is a supporter of the Neighborhood Resilience Corps’ youth training effort. York said the opportunity to train young people is important.
“Anytime we can do that with young adults who are interested, it’s always a great idea,” he said. “We might do the conversions, but if we can get that benefit and inspire and teach young adults, why not.” York was referring to the city’s programs that remove thirsty lawns and replace them with drought tolerant landscapes.”
Boulder-based Resource Central, another agency that has partnered with the CWCB on statewide conservation efforts, said it is seeing an unprecedented number of requests for its services.
“Demand for conservation programs is off the charts,” said Neal Lurie, president of the nonprofit agency. “We’ve seen more interest in the first three weeks of this spring season than we did all of last year.
“To me that says the message is resonating with people that they have an important role to play,” he said. “That’s good news.”

The Lower Basin States of Arizona, California, and Nevada today advanced a plan to stabilize the Colorado River through 2028, responding to declining reservoir levels, record low inflows to Lake Powell, and increasing risk of reaching critical elevations at both Lake Powell and Lake Mead.
Earlier in the post-2026 process, the Lower Basin took a significant step by proposing 1.25 million acre-feet in annual reductions, with an additional 250,000 acre-feet from Mexico, totaling approximately 1.5 million acre-feet per year.
This proposal builds on that foundation with an expanded system conservation program across the Lower Basin with an estimated contribution of at least 700,000 acre-feet. In total, the plan identifies up to 3.2 million acre-feet of water savings to the system through 2028.
The proposal is an integrated package addressing Lake Powell releases, Upper Initial Unit operations, Lower Basin reductions, additional conservation, use of Intentionally Created Surplus, and system infrastructure improvements. Lower Basin contributions are contingent on these coordinated operations to ensure system stability as well as appropriate funding.
“With this proposal, the Lower Basin is putting forth real action to stabilize water supply along the Colorado River. We’re putting forward additional measurable water contributions for the system. Without that, the system will continue to decline,” said JB Hamby
“This proposal is about moving from ideas to implementation,” said John Entsminger. “It pairs real measurable water contributions with sensible dry-condition operations at Lake Powell and across the Upper Initial Units. Now is the time for every water user in the Basin to double down on water conservation as we face historically dry hydrology.”
“This proposal reflects the creativity and commitment of water users across the Lower Basin who continue to step forward with solutions that support the river,” said Tom Buschatzke. “We have shown that collaborative, voluntary efforts and reductions that are certain can produce meaningful water savings.”
The Lower Basin states recognize the Upper Basin’s call for mediation and are open to that process. However, current conditions require immediate, measurable water reductions from every state. The Lower Basin states stand ready to engage in a meaningful process for long-term solutions while encouraging the Upper Basin to step forward now with verifiable water contributions to help stabilize the system and support a near-term, seven-state bridge.
The Lower Basin states confirmed that the proposal preserves legal accountability under the Colorado River Compact, including Upper Basin delivery obligations, while maintaining a clear path toward a broader agreement among all seven Basin States.
The plan has been advanced to the federal government for consideration as part of the ongoing post-2026 planning process and is intended to provide a near-term bridge through 2028 while long-term operating guidelines are finalized.
Implementation of key elements of the proposal, including expanded system conservation, will require federal partnership. The proposal remains subject to approval by the Arizona Legislature and relevant California and Nevada water agency governing boards.

The situation on the Colorado River is dire. Flows have reached historic lows and water saved in major storage reservoirs is approaching critical elevations. To date, solutions to the crisis have been elusive, with lengthy litigation looming as the seven states that share the river have been unable to agree on an appropriate remedy to the situation. That is why today’s announcement that the Lower Division States of Arizona, California and Nevada have come together to announce a bridge proposal that will support the entire Colorado River system through 2028 represents a welcome lifeline and cause for hope. This three-state proposal is a two-year, comprehensive package that will commit a minimum of 3.2 million acre-feet of Lower Division water savings in Lake Mead by 2028
The proposal is a bridge, a pathway to future operations that extend beyond the expiration of the existing river operating guidelines at the end of 2026. However, this massive sacrifice by the Lower Division States is only possible by implementing the entire proposal, which requires a series of critical actions by the federal government. The federal government must commit the remainder of Colorado River drought funding to offset impacts to Lower Division users, create a tribal pool to meet federal responsibilities to tribal communities, and use the reservoirs upstream of Lake Mead for their foundational purpose — meeting water delivery obligations to the Lower Division. Congress built those upstream dams for the purpose of releasing water and meeting minimum obligations to the Lower Division under the Colorado River Compact during an extended drought like the one we face today and now, the dams must be used as mandated by Congress.
Today’s announcement is the latest in a series of actions by the Lower Division States to preserve the stability of the Colorado River system. Lake Mead would be in the mud if not for Lower Division water users leaving water in the lake to protect the system, and every drop that has been left in Lake Mead is benefiting Lake Powell and the Upper Division by allowing for less water to be released downstream.
But Lower Division actions alone cannot protect the entire system from extraordinarily dry years. This year is an example where, despite the Lower Division’s ongoing reductions and contributions, Lake Powell needed additional emergency action.
While this new Lower Division bridge requires no action from the Upper Division states, it is well past time that the Upper Division States agree to be part of the solution by committing to verifiably conserve water and end their out-of-touch demand that the Upper Division be allowed to increase their total uses from a shrinking system.
The Central Arizona Project applauds the Lower Division States for developing the proposal and urges the federal government to speedily approve this emergency effort to bridge the river system through 2028.
The Center for Biological Diversity, the San Carlos Apache Tribe and the Lower San Pedro Watershed Alliance today filed a notice of their intent to sue the U.S. Bureau of Land Management and the U.S. Fish and Wildlife Service over the Copper Creek Exploration Project near Mammoth, Arizona. The groups say the agencies violated the Endangered Species Act by allowing mining exploration drilling that threatens Mexican spotted owls and other imperiled wildlife.
“Federal officials were warned that Mexican spotted owls are in the area but pushed this mining project ahead anyway and skipped steps required by law,” said Russ McSpadden, a Southwest conservation advocate at the Center for Biological Diversity. “The Endangered Species Act is supposed to protect imperiled wildlife before damage is done, not after agencies brush aside the evidence and greenlight industrial drilling. This mining project is clearly illegal and it must be stopped.”
Today’s notice focuses on Mexican spotted owls, rare birds who depend on the rugged canyon and forest habitat of the Southwest. Federal data estimates there are roughly 1,300 known owl territories in the U.S., representing only a few thousand birds in small, fragmented and declining populations. Mexican spotted owls have been protected as threatened under the Endangered Species Act since 1993.
“The Lower San Pedro watershed is one of Arizona’s most important wildlife corridors, and this exploration project is pushing industrial disturbance into a landscape that is already under pressure,” said Melissa Crytzer Fry, chair for the Lower San Pedro Watershed Alliance. “When agencies ignore clear evidence and fail to follow the law, local communities are left to defend the river, the habitat and the species that make this place irreplaceable. We shared trail camera images with the BLM showing Mexican spotted owls in the area and were utterly ignored.”
The groups say the BLM approved the drilling project last summer despite receiving photographs showing Mexican spotted owls in the area. The agency still concluded the species was “not present” and failed to initiate consultation with the Fish and Wildlife Service, as required by the Endangered Species Act.
The Copper Creek project is already underway, bringing industrial drilling, bright lights, heavy noise, truck traffic, surface disturbance and groundwater pumping into sensitive habitat in and around Copper Creek Canyon, an important tributary of the Lower San Pedro River. These public lands and waterways support significant wildlife resources, including habitat for one of the Southwest’s most vulnerable owl species, and require management based on the best available science.
The notice letter also challenges the agencies’ analysis of harms to the threatened yellow-billed cuckoo, saying they failed to adequately assess how exploration-related groundwater pumping and noise could affect the bird’s habitat in the Lower San Pedro watershed. Cuckoo rely on healthy streams for habitat and prey during their nesting season.
The agencies failed to analyze how extensive helicopter surveying of the project area may harm both Mexican spotted owls and yellow-billed cuckoos. Aerial surveillance requires helicopters to fly extremely close to the ground, causing loud noise and surface disturbance that can be disruptive to wildlife.

April 29, 2026
Dust storms, while often seen as harmful, can play an unexpected role in enhancing rainfall. Global observations show that 7-day accumulated precipitation after dust storms exceeds dust-free conditions by up to 9.6 millimeters. Numerical simulations further confirm that dust particles act as ice nuclei, thereby promoting cloud formation and increasing rainfall through the ice crystal effect. Moreover, in regions with rising anthropogenic aerosols, dusts determine precipitation patterns. While elevated levels of anthropogenic aerosols alone tend to boost weak rainfall, the presence of dust aerosols reduces light precipitation and enhances heavier precipitation. Collectively, these findings reveal a dual role of dust storms in shaping global precipitation patterns while adversely affecting the human living environment. This research establishes a mechanistic framework for understanding how dust affects extreme precipitation at the global scale, advancing predictive capabilities for heavy precipitation.

“By taking voluntary measures now to reduce water use, Utilities customers can actively help lower the chance of mandatory water restrictions if conditions worsen,” the news release stated.
Fort Collins Utilities and East Larimer County Water District, or ELCO, which are two of the city’s three major water providers, are asking customers to:
Limit lawn watering to no more than two days per week.
Avoid watering between 10 a.m. and 6 p.m.
The West Fort Collins Water District is required to follow city-issued water rationing and restrictions, according to its website. Sunset Water District is managed by ELCO.
On Tuesday, April 21, the Colorado River District board of directors unanimously supported initial actions in response to extreme drought conditions on the western slope. The board’s actions allocated $450,000 from the District’s Community Funding Partnership for strategic water releases from District-owned, District Enterprise, or other storage pools across the western slope. The board also acted to suspend a previous water marketing policy that allowed contracts on a first-come, first-serve basis, instead taking staff recommendation to develop a cooperative approach that best uses available supplies to meet critical needs. The board delegated authority to its Water Supply Projects Committee to consider and approve subsequent contract water leases and funding allocations.
“This action alone won’t solve the drought, but it will help meet critical water needs in the short term,” said Hunter Causey, director of asset management and chief engineer for the Colorado River District. “Our reservoirs were built to help communities on the western slope weather exactly this kind of year. Maximizing the use of our available storage now is the responsible thing to do.”
“We were already bracing for a dry summer, but the low snowpack was absolutely flattened by extreme heat in March, leaving statewide water supplies facing unprecedented gaps,” said Colorado River District Board Vice President and Grand County rancher Mike Ritschard. “Irrigators and agriculture producers in Colorado are familiar with working within uncertainty, but when supplies are this limited, we know we have to be especially conscious of balancing our use with the health of the system as a whole.”
The Board also prioritized its contract water supplies to first support critical domestic and municipal needs, while striving to then address agricultural and industrial needs. Prioritizing these uses will also boost stream flows and reduce water temperatures through strategic releases. For domestic and municipal uses, the board directed staff to work with water suppliers and land use authorities to provide clear guidance that outdoor water use for lawns and ornamental applications be strictly limited.
“The reality is that in a year like this, any water that you put on your lawn is water that will not show up in the river,” said Andy Mueller, Colorado River District general manager. “This drives up water temperatures and negatively impacts the health of the river for everyone downstream, including our local farms and regional food production. We are asking all residential water users and municipalities to consider limiting outdoor water use to one or two days a week. This year, we all need to be asking if we value healthy rivers and local food production over green lawns.”
Over the next few weeks, Colorado River District staff will work with constituents and other partners to determine the best use of available supplies in a manner that meets critical needs of the residents of the River District and brings benefits to as many communities as possible.
Please refer to the staff memo, linked HERE, for more details on the initiative.
Breckenridge Town Council approved more stringent water restrictions, limiting outdoor watering to two days per week, as town officials respond to drought conditions and declining streamflows in the Blue River. The new Stage 2 restrictions come as the town faces a water shortage tied to this year’s historically low snowpack and reduced runoff into Goose Pasture Tarn, according to Shannon Cahill, town engineer. The restrictions officially take effect on Friday, May 1.
West Drought Monitor map April 28, 2026.
“We remain in a sphere of drought here in Summit County, throughout the state and the greater Western U.S.,” Cahill told council members at a meeting Tuesday, April 29. “The historically low snowpack has already directly impacted streamflow in the Blue River, and this subsequently affects the town’s ability to supply treated water to our customers.”
Until this week, Breckenridge allowed outdoor watering three days per week. The new temporary restrictions reduce that to two days in hopes of cutting outdoor water usage by roughly 30%. The town largely sources its drinking water from snowmelt (and other high-altitude surface water) collected in the Blue River Basin…The new restrictions exempt any newly installed landscaping, along with hand watering and drip irrigation for flowers and plants. Council member Dick Carleton clarified whether downtown businesses could continue watering flower baskets and using microsprayers.
…as the city gears up for an unprecedentedly dry summer, it will begin ramping up enforcement on water users who violate the stage 2 water restrictions. That will include issuing formal notices of violation and collecting fines for repeat violations.
“We are taking this year more seriously, given that it’s conditions we haven’t quite seen before,” Loughlin Molliconi said. “We want to make sure we can prioritize the most important uses of municipal water without having to degrade any environmental protections or streamflow.”
The city water department has issued 11 formal notices of water use violations in 2026, Loughlin Molliconi said. One notice was issued last week. Ten were issued on Wednesday. They were all first-time violations, which don’t come with fines…Aspen City Council declared a stage 2 water shortage last August after declaring a stage 1 water shortage in June. The declaration came after a lackluster monsoon season, and has remained in place because of unusually high winter temperatures that impacted snowfall accumulations and the snow water equivalent in the Roaring Fork watershed. Stage 2 water restrictions are mandatory. Watering of any lawn, garden, landscaped area, tree, shrub or other plant is prohibited from 9 a.m. to 6 p.m. Household watering schedules are also mandatory.
Rain continued to bypass the central and southern High Plains, leaving rangeland, pastures, and winter wheat in desperate need of moisture. Farther east, however, showers and thunderstorms continued to ease drought across the eastern Plains, extending into the mid-South and Mississippi Delta. Some of the heaviest rain, accompanied by locally severe thunderstorms, fell from eastern Kansas into the lower Midwest. The remainder of the Midwest also received some precipitation, although some of the region’s wettest areas in the Great Lakes States got a break from the excessive rain that had led to pockets of record flooding earlier in the month. In contrast, much of New England and northern sections of New York were cool and dry. Elsewhere, unsettled, showery weather prevailed in the West, mainly north of a line from central California to the central Rockies, boosting topsoil moisture, delivering high-elevation snow, and reducing irrigation demands. However, any precipitation did not fundamentally change a mostly bleak Western water-supply outlook for the remainder of the spring into the summer of 2026…
Precipitation delivered drought relief to some areas, including parts of southern South Dakota and eastern sections of Nebraska and Kansas. Still, by April 26, topsoil moisture—as reported by the U.S. Department of Agriculture—was rated at least 40% very short to short in all the region’s states, except North Dakota, and led by Colorado (95%). Winter wheat continued to struggle due to drought and recent freezes, with 65% of Nebraska’s crop rated in very poor to poor condition on April 26, along with 54% in Colorado and 41% in Kansas. Drought continued to generally worsen in eastern Colorado and western sections of Kansas and Nebraska…
Colorado Drought Monitor one week change map ending April 28, 2026.
Any changes in the West were mostly minor and mixed, as cooler weather prevailed and spotty precipitation occurred. In most areas, Western precipitation did not alter bleak water-supply prospects, since most of the mountain snowpack has already melted, except in the northern Rockies. Already in late April, fears of an hydroelectricity generation crisis in the Colorado River Basin have led the Department of Interior to start sending water from Flaming Gorge Reservoir downstream to Lake Powell to help boost water levels. The Department of Interior also indicated that water normally destined for Lake Mead, farther downstream, would be held in Lake Powell. Despite overall lack of impact on Western supplies, any precipitation was largely welcomed, due to positive impacts such as a boost in topsoil moisture and a reduction in irrigation demands. In fact, enough precipitation has recently fallen to warrant a slight reduction in drought intensity in a few areas, including parts of western Colorado, northeastern Oregon, and southeastern Washington…
Late in the drought-monitoring period, significant rain overspread portions of the South, resulting in broad reductions in drought intensity. Some of the heaviest rain fell from eastern sections of Oklahoma and Texas into portions of Arkansas, Mississippi, and northern Louisiana. Still, more rain will be needed to ensure full drought recovery, since many of the hardest-hit areas had slipped into extreme to exceptional drought (D3 to D4) in recent weeks. Meanwhile, western sections of the South—including western Oklahoma and western Texas—remained critically dry, leading to poor rangeland, pasture, and winter wheat conditions, as well as a chronically elevated wildfire threat. Statewide, winter wheat in Texas was rated 56% very poor to poor on April 26, along with 45% in Oklahoma…
Looking Ahead
During the next several days, active weather across the South should lead to 1- to 4-inch rainfall totals from much of Texas to the southern Atlantic States. However, some Southern thunderstorms may produce large hail, damaging winds, and isolated tornadoes. The moisture will have a sharp northern edge, with little or no precipitation expected during the next 5 days across the northern and central Plains and Midwest. Generally dry weather will also cover the West, aside from late-season snow in the central and southern Rockies. Elsewhere, a cool pattern across the nation’s mid-section will strengthen, with frost and freezes possible into the weekend across the northwestern half of the Plains into the upper Midwest. By Saturday morning, scattered frost could extend as far south as the Ohio Valley and the southern High Plains.
The NWS 6- to 10-day outlook for May 5 – 9 calls for the likelihood of cooler-than-normal conditions in most areas east of the Rockies, while warmer-than-normal weather will be confined to an area stretching from the Pacific Coast to the northern Rockies, including the Great Basin and northern Intermountain West. Meanwhile, near- or below-normal precipitation from the Pacific Northwest into the upper Midwest should contrast with the likelihood of wetter-than-normal conditions across the remainder of the Lower 48 States.

KEY POINTS
Glen Canyon Dam, completed in 1963, was not designed to be operated at extremely low water levels in Lake Powell.
The decline of Lake Powell is putting hydropower generation and downstream water deliveries at risk.
The Bureau of Reclamation, the federal water manager, is studying options for retrofitting Glen Canyon Dam.
In the span of U.S. history certain years are turning points, milestones in the nation’s story. 1776. 1865. 1929. 1968. Circumstance and consequence conspire to make it so.
For the Colorado River and those who rely on it, 2026 is on the verge of similar prominence. Circumstances in the basin today are that urgent.

A slow-developing water supply calamity, decades in the making, has boiled over, like a cold war turning hot. Extreme heat in March – triple-digit temperatures never witnessed that early in the year – obliterated a meager snowpack. The basin’s big reservoirs, the supposed buffers against short-term drought, were already uncomfortably low after a quarter-century of declining river flows. They will drop even lower. The amount of water flowing this summer into Lake Powell, the nation’s second-largest reservoir, will be one of the smallest ever measured, barely a trickle.
“This is unprecedented, but it’s not unpredicted,” said Eric Balken, executive director of the Glen Canyon Institute. “I like to say that this is the most predicted disaster of all time.”
Lake Powell is formed by Glen Canyon Dam, a striking 710-ft tall concrete arch braced against ruddy sandstone walls. It plugs the Colorado just after the river enters Arizona. Meant to ensure water deliveries to the lower basin states of Arizona, California, and Nevada, Glen Canyon Dam was finished in 1963 to complement the Colorado River’s audacious engineering that distributes water through mountains and uphill to the largest cities in the Southwest and to the region’s most productive farmland. When full, Lake Powell holds enough water to flood the entire state of Virginia to the depth of one foot.
Climate change and water demand that still exceeds supply have flipped the engineering script. Lake Powell is less than 25 percent full today. Glen Canyon Dam, instead of being a guarantor of water, is now the most significant water chokepoint in the basin. The hard-won asset has become a glaring liability.

The reversal of fortune is because of how Glen Canyon Dam was designed. The dam was never meant to be operated at the extremely low water levels that Lake Powell is rapidly approaching. Doing so for extended periods of time could damage the pipes that move water through the dam, according to the Bureau of Reclamation, the federal agency that manages the structure.
Reclamation is now studying its options for retrofitting Glen Canyon Dam to accommodate a lower Lake Powell. It expects to release those findings later this year or in early 2027. As any home remodeler knows, renovating an aging structure is neither quick nor cheap, especially when failure could have disastrous consequences.
In the short term, Reclamation is relying on operational band-aids for Glen Canyon Dam and Lake Powell. With the consent of the seven states in the basin – Arizona, California, Colorado, Nevada, New Mexico, Utah, and Wyoming – the agency took unprecedented action this month to prop up the reservoir. Releasing more water from upstream reservoirs and holding back more in Powell will delay Glen Canyon’s infrastructure reckoning. But that day will soon come, and Reclamation’s answer to the dam’s engineering problems will have far-reaching implications – not only for the reliability of the basin’s water supply, but also for its power customers, ecology, and recreation economy.
An Assessment Deferred
Dams are difficult to manage under any circumstance. Management is even more troublesome when operators must balance multiple, conflicting objectives. In Glen Canyon’s case those objectives are water supply, flood control, hydropower generation, and releasing water to protect the ecology downstream in the Grand Canyon – namely, beach-building and threatened native fish like the humpback chub. This is in addition to ensuring the safe operation of the dam itself.
How to operate Glen Canyon Dam and Hoover Dam, its larger downstream sibling, is what the seven basin states and Reclamation are attempting to figure out right now. The current agreement covers operations through 2026. Reclamation published a draft environmental impact statement, or EIS, in January that would impose severe cuts on water users in the lower basin, particularly Arizona, in part to protect Glen Canyon Dam’s fragile infrastructure.
For that reason, water users in the lower basin and elsewhere support an engineering fix for Glen Canyon Dam. Many were incredulous that Reclamation did not include an assessment of dam modifications in its draft environmental analysis.
“This EIS could have been a great avenue to look at real changes at Glen Canyon Dam that could solve the water delivery problem and some of the ecological problems, too,” Balken said.
Patrick Dent is the assistant general manager for water policy at the Central Arizona Project (CAP), which delivers Colorado River water to the densely populated center of the state. He said that CAP does not favor any particular fix – only one that provides dam managers with more flexibility.
“Our primary interest is that they could release water at a lower lake level,” Dent said.
The Gila River Indian Community, which receives Colorado River water through CAP, told Reclamation that the agency has a duty to safeguard the tribe’s water rights, which are at risk if the dam cannot release enough water. “The United States must take action to fix Glen Canyon Dam,” Gov. Stephen Roe Lewis wrote in a March 2026 letter.
The Colorado Water Conservation Board, which represents that state’s water interests, said it supports a reevaluation of Glen Canyon Dam, but “in a separate action” from the EIS.
Becki Bryant, a Reclamation spokesperson, said the agency will release an appraisal study assessing three dam modification alternatives at the end of this year or in early 2027. Any action beyond the study, she said, requires congressional authorization and funding.

‘Antiquated Plumbing’
The tool for managing the dam’s multiple objectives, which are a legislative requirement as well as a practical necessity, is the water held in Lake Powell, said David Wegner, a scientist who has worked on Glen Canyon policy for more than four decades. But even water has limits when the engineering is inadequate. “Sadly, these dams were not built for multiple objectives,” Wegner said. And Glen Canyon was certainly not built for extremely low water, he added.
The problem with Glen Canyon is what a coalition of environmental groups calls the dam’s “antiquated plumbing.” The groups – Glen Canyon Institute, Great Basin Water Network, and Utah Rivers Council – published a report in August 2022 that outlined these engineering deficiencies.
Water can exit Glen Canyon in only three ways. One is the spillways, a pressure-release valve for flooding, which are located at elevation 3,648 feet, near the top of the dam. They are irrelevant today. Lake Powell rests 122 feet below them.
The main exit point is through the eight penstocks, the 15-foot diameter tubes that move water through the turbines to generate hydroelectricity. The penstocks are incapacitated when Powell drops below 3,490 feet. (The lake today is 36 feet higher than that level.) If the lake falls below what is known as minimum power pool, hydropower generation also ceases.
If that happens, water must be released through four 8-foot diameter pipes called the river outlet works. Smaller than the penstocks, the river outlet works are located at elevation 3,370. Below that elevation water cannot be released from Powell, a status known ominously as “dead pool.” (Functionally, the river outlet works may be useless at elevation 3,394, Reclamation says.)
The environmental groups identified two limitations with the river outlet works. One is that they were not designed to be operated full-time. They are a role player, not the star. The other is that their smaller size means less water can pass through them. That’s a problem because the upper basin states of Colorado, New Mexico, Utah, and Wyoming are required to send a set amount of water downstream to the lower basin, according to the 1922 Colorado River Compact that divided the river.
The flow restrictions imposed by the river outlet works, if they had to be used full time, means that the upper basin could violate the compact, which could mean water cutbacks imposed by the lower basin.
“It’s just so counterintuitive that the tool that was designed to meet this delivery obligation” – the construction of Glen Canyon Dam – “is now going to be the roadblock that may prevent the delivery obligation from being met,” said Balken of the Glen Canyon Institute.
The engineering problems are not a new discovery. Wegner, who was with the Bureau of Reclamation at the time as its Grand Canyon environmental studies manager, helped lead a 1987 National Academies report on Glen Canyon. The report recommended that the Interior Department consider the “installation and operation of multiple outlet structures” at Glen Canyon, which would give dam managers more flexibility with water releases.
Glen Canyon’s structural problems were substantiated in 2023, when Reclamation used the river outlet works during an experimental “high-flow” release of water to flush sediment downstream and rebuild eroding Grand Canyon beaches.
The high-volume release caused pitting, or cavitation, within the river outlet works, a risk that was heightened due to the physics of water when Lake Powell is low. Reclamation coated the pipes with epoxy as a temporary fix to prevent more damage, a process that took several months. The agency has since used two small-scale physical models at its Technical Service Center in Denver to test dam operations at low water levels and the effect on infrastructure.
Reclamation acknowledged the limitations of the river outlet works in a technical memopublished in March 2024 by Richard Lafond, director of the agency’s Technical Service Center. The memo’s conclusions were endorsed by the top decision-makers in Reclamation’s Upper Colorado River Office.
“Long term operation of the river outlet works will result in accelerating regular operation and maintenance tasks,” LaFond wrote. Reclamation should “not rely on the river outlet works as the sole means for releasing water from Glen Canyon Dam.”
Wegner put it in starker terms. If the river outlet works had to be relied upon and the pipes began to erode again, then Reclamation could potentially lose control of water flows.
“Potentially that could fail,” Wegner said, meaning an inability to control water releases through the dam if the pipes are structurally compromised. “And if that fails, now you have a catastrophe on your hand and you have limited options to manage that catastrophe.”
In other words, there would be no way to release water downstream into the Grand Canyon and into the lower basin.
Neither Quick Nor Easy
What fixes are possible? Reclamation received $2 million from Congress in the fiscal year 2022 budget for an appraisal study.
Reclamation outlined three engineering possibilities in a 2023 presentation, most of which centered on preserving hydropower generation as Lake Powell declines.
One possibility is a new, lower intake that uses the existing power generation turbines. An intake located deeper in the reservoir would allow Glen Canyon to pass water in what is currently dead pool. But it would entail “increased risk from penetration through the dam.”
The second would connect new power generation equipment to the river outlet works.
The third option is tunneling through the canyon wall and installing a new underground power station. This would also provide more flexibility for water releases.
Reclamation also included three operational or policy changes for power production, including investing in wind and solar to offset hydropower declines.
Other ideas that seemed kooky and fringe just a few years ago – draining Lake Powell and filling Lake Mead first; changing the basin’s water accounting system – are now being discussed throughout the basin with more seriousness and candor.
Beyond that presentation, Reclamation has not said much publicly about dam modification. The agency declined an interview request to discuss Glen Canyon Dam’s engineering problems.
Whatever direction Reclamation chooses – an option outlined above or something new – the process will not be quick or easy. Any change to Glen Canyon must go through an environmental analysis and public comment period. Congress will have to authorize actions and appropriate the funds. Construction alone will take years.
Wegner, who was the staff director for the House Natural Resources Water and Power Subcommittee from 2008 to 2014, knows the difficulty and sees a lack of leadership. “There’s nobody in Washington who has been willing to lead the charge trying to get Congress to provide authorized funding to do this sort of work.”
‘Reservoir Triage’
Because Reclamation is not confident it can operate the river outlet works for an extended run, the agency is focused on keeping Powell above elevation 3,500 feet.
Protecting 3,500 feet comes with all sorts of baggage. It preserves hydropower generation, which power customers appreciate. But in effect the redline at that elevation strands some 4.4 million acre-feet in Lake Powell. (Only 3.7 million acre-feet is technically accessible with the current plumbing.) Some have called this elevation a “de facto” dead pool. Thus, the agitation in the lower basin for a plumbing system within the dam that provides access to this water.
Balken said that downstream water deliveries, not preserving hydropower, should be Reclamation’s biggest concern.
“When these decision makers are talking about Glen Canyon Dam from only a hydropower perspective, I think it’s missing the larger point, which is the dam is about to become the biggest roadblock of water deliveries that the basin has ever seen,” Balken said.
Flaming Gorge Reservoir, on the Green River, straddles the Wyoming-Utah border south of Rock Springs. The Flaming Gorge dam, on the Utah side, was completed in 1964 and is a critical component of the Colorado River water storage system. The Green River, the chief tributary to the Colorado River, originates in the Wind River Range, flows to Flaming Gorge Reservoir, then connects with the Colorado River in Canyonlands National Park in Utah.
To avoid the infrastructure risks of dropping below 3,500 feet, Reclamation has started to take extraordinary action. The agency has two emergency levers it is pulling. One is to hold more water back in Lake Powell. Reclamation cut water releases to the legal minimum this year, something it has never done. The other is releasing more water from Flaming Gorge, a reservoir upstream that is in better shape.
As Balken describes it, “This is reservoir triage.”
These emergency actions have serious side-effects. Upstream, Flaming Gorge is expected to lose 35 feet of elevation by next spring, once the extra water has been released. That will hurt the recreation economy of northeastern Utah and southwestern Wyoming – fewer boat ramps in the water, less fishing access.
These upstream releases have limited utility, Wegner said. “You can do that once or twice. But you got to then depend upon Mother Nature refilling those reservoirs upstream.”

Downstream, Lake Mead will drop quickly and it too will approach a level in which hydropower generation at Hoover Dam severely drops. Algal blooms in a warmer, shallower lake could be a problem. “They’re going to be robbing Mead to pay Powell,” Balken said.
Trying Not to Hit Bottom
The idea of dead pool – when Lake Powell can no longer release water – was almost inconceivable when the reservoir was designed and filled. The official device for measuring Lake Powell’s elevation ends at the top of the penstocks, at elevation 3,477.5 feet. According to Reclamation’s 2024 technical memo, “This is an indication that reservoir elevations below minimum power pool” – 3,490 feet – “were not anticipated.”
Cavitation at the Glen Canyon Dam, the cause of the emergency in 1983 via Flow Science.
Reclamation finished filling the reservoir in 1980. Three years later, after an intense El Niño winter, the dam’s upper limits were tested. Floodwaters in the summer of 1983 nearly broke the dam. Such volumes are almost inconceivable now.
In a typical year, Lake Powell would be rising in late April, flush with the deposits of snowmelt from headwater basins in the Rocky Mountains. Not this year. The snowpack peaked in many basins in late February or early March. What little snow there was has already melted. As of April 28, Lake Powell inflows are projected to be just 16 percent of average. Lake level forecasts from mid-April showed a long downward slope for the next 12 months. Those projections were what triggered the emergency release of water from Flaming Gorge and the reduction in Lake Powell releases.
Scientists have been warning about circumstances like this for years. In a defining period for the basin, all the predictions of water supply shocks in the Colorado River from the past two decades are coming to pass.
“We should have been prepared for this,” Balken said.

April 26, 2026
The staff at the Colorado River District showed this slide during a session on Colorado River hydrology at the district’s board of director meeting in Glenwood Springs this past Tuesday afternoon.
Here in metro Denver, the staff of Big Pivots said something profound like “holy moly!”
With moisture coming into Colorado during the next two weeks, it’s possible that the runoff into Lake Powell may surpass that of 2002. This slide says that right now, at Cameo, the gaging station on the Colorado River, east of Palisade, it looks like the spring runoff peaked in late March. The usual is in early June.
Another takeaway from the River District meeting was about Green Mountain Reservoir. The dam that creates the reservoir was built from 1938 to 1943, giving the Western Slope a way to store water as part of the Colorado-Big Thompson diversion that came after World War II. The normal allotment of the reservoir storage for downstream irrigators, mostly in the Grand Junction area, is 66,000 acre-feet.
For the first time in the history of Green Mountain, said Andy Mueller, the River District’s general manager, the water is unavailable. Instead, the river district is tapping various pools of water over which it has control to come up with a thimbleful here, a cup there. A creative solution, Mueller called it. Irrigators won’t become whole, but they will get some help.
“We’ll survive, and we will continue to survive,” said Mike Ritschard, a director from the Kremmling area and a fourth-generation rancher there, said during a roundup of reports from board members.
Created in 1937, one of the ramifications of the Colorado-Big Thompson water diversion, the River District has primary responsibility for water matters across 15 of the 20 Western Slope counties.

When Donald Trump was elected president for the second time, we all knew what was coming to the nation’s public lands: The administration would favor extractive uses by eviscerating environmental protections, rolling back regulations, and leasing out as much land as possible while handing out drilling permits like Shriners throwing candy at a parade.
Yet there was one realm where I figured the administration couldn’t bestow any more deregulatory gifts, namely public lands grazing. It’s not that I thought Trump would clamp down on the destructive practice, it’s just that I figured the status quo was about as permissive as it could get. Past administrations, be they Democratic or Republican, have generally shied away from updating or reforming public lands grazing policies out of fear of inflaming the West’s cowboy culture — even if it is based largely on myth.
But Trump, his Interior Secretary Doug Burgum, and Agriculture Secretary Brooke Rollins are intrepidly going where previous administrations did not dare: grazing reform. Well, sort of, though maybe not in the way public lands lovers might have hoped. In fact, they are doing their best to make grazing policy even more lax with a goal of getting more cattle out there to trample public lands, cryptobiotic soils, and cultural sites.
Last month, Burgum and Rollins announced an MOU between the two agencies designed to “boost the supply of American born, raised, and harvested beef” by cutting “bureaucratic red tape” and giving the livestock industry more control. The MOU has a goal of “maintaining grazing capacity wherever possible, including no net loss of Animal Unit Months within allotments,” even if those allotments are degraded or in poor health. In Burgum’s words, one goal is to “preserve America’s ranching heritage for generations to come.” Forgive me for getting anxious whenever I see “heritage” used in conjunction with public lands.
“Today’s signing sends a clear message: the Trump administration is putting America’s farmers and ranchers first,” said Secretary of Agriculture Brooke Rollins. Which brings up the question of what message the administration was sending in February when Trump signed an executive order to quadruple beef imports from Argentina in an effort to keep Big Macs affordable.
🗺️ Messing with Maps 🧭
To help it carry out its mission, the Bureau of Land Management has released an interactive map aimed at putting more cattle and sheep back on public lands. The “federal grazing lands potentially available” map shows allotments that have been vacated, often as a result of deals brokered by environmentalists, with the intent of peddling the tracts to livestock operators. While there’s no guarantee that the BLM would lease out all of the vacant tracts, the presence on the map of the ones vacated for environmental purposes is enough to set off alarm bells.

For example, the map includes 10 allotments in the high country around Silverton, Colorado, totaling about 70,000 acres. In 2023, the National Wildlife Federation paid the Etchart Sheep Ranch to vacate five of these allotments in an effort to give Rocky Mountain bighorn sheep more breathing room and protect them from diseases transmitted by domestic sheep. The deal was made with the hope that the leases would be retired permanently. Yet the inclusion on the map indicates they could see domestic sheep once again, emphasizing the need for legislation that would make such retirements perpetual.
Also on the map are the Flodine Park and Yellowjacket allotments in Canyon of the Ancients National Monument near the Colorado-Utah border. In 2005, a rancher gave up the allotments, north and south of McElmo Canyon, respectively, and sold 4,500 acres of adjacent private land to the BLM to add to the national monument. Both allotments and the private land contain a number of intermittent streams, shallow canyons, and numerous cultural sites. They had been grazed relentlessly for decades prior, and showed the wear and tear—much of the cryptobiotic soil had long before been trampled and destroyed and invasive cheat grass had infiltrated the grazed areas. An archaeological assessment conducted later found grazing had damaged dozens of sensitive and cultural sites in the areas.

In 2010, the BLM, which manages the monument, issued a new resource management plan, which allowed for continued grazing, but also opened the door to permanently retiring vacant grazing allotments if they fail to meet BLM rangeland health standards or when grazing is negatively impacting cultural sites. Five of the 28 allotments in the most heavily visited areas—including Sand Canyon—were cancelled, but not the Flodine Park and Yellow Jacket allotments, which were still in retirement at the time.
Instead, the local county commissioners and a group of ranchers pressured the BLM to reauthorize grazing on both allotments—to bring them out of retirement, if you will. The BLM acquiesced, but environmentalists and tribes with roots in the area fought back, forcing the agency to do a more thorough environmental analysis of the proposal. The opposition was enough to prompt the agency at least to delay issuing any leases, and the allotments remain in limbo.
Meanwhile, a team of scientists assessed the healing process on the Flodine Park and Yellow Jacket allotments, which by then had been cow-free for 11 years (though feral horses had grazed there). They compared biocrusts on those allotments to a fenced enclosure that hadn’t seen grazing for 53 years and a plot that was being actively grazed. What they found was both predictable and remarkable: The longer a plot went without cows, the healthier it was, as summed up by these graphs.

While the natural landscape can eventually heal itself, livestock’s damage to the cultural landscape is irreversible. BLM surveys identified 266 cultural sites on the two allotments, including 35 with “standing architecture.” At least 43% of those had been damaged by livestock.
Now what’s left may be in danger, too, at least if those allotments’ presence on the new map is any indication. And guess what? Packing these allotments isn’t going to make that steak any cheaper. Only about 1% of American beef is grazed on public lands.

⛈️ Wacky Weather Watch ⚡️
If you were to get all of your information about the West’s climate from daily weather reports and road condition websites, you might think that April snow showers and deep freezes had ended the snow drought and would lead to big May streamflows. After all, it snowed enough in Colorado to turn roads to slip-and-slides and causing a 75-car pileup on I-70 near the Eisenhower Tunnel. The temperatures dropped low enough to wipe out most of the fruit blossoms the March heat wave tricked into blooming early. Only the farmers who used extraordinary measures — starting fires or smudge pots in the orchards, running wind machines, etc. — could save some of their summer harvest.

Sure, the snow that did fall in April helped, but only enough to elevate snowpack levels to, well, the lowest on record (only by a slightly smaller margin than before). And the freeze was deep, which helped extend the spring runoff in the few areas where there was any snow left. But even there, I suspect that peak runoff has already come and gone (though I’m not calling the Predict the Peak contest yet!).
I flew over Colorado’s mountains the other day and was rather shocked at the dearth of snow, even on the highest peaks. Mt. Blue Sky, formerly Mt. Evans, had only a few patches of white left — at 14,130 feet in elevation. Everything below 10,000 feet appeared to be snowless. While the San Juan Mountains appeared to be in slightly better shape, it was still looking pretty dry. The Animas River watershed’s snowpack remains lower than it was on 2002 on this date.
Meteorological records dating back 130 years show a handful of years with winters drier than the 2025-26 winter, said Rebecca Briesmoore, a water resources engineer with the Colorado River District.
“But it has been the warmest by far … that has really been the headline: It wasn’t the driest, but it was the warmest — and that is having a huge impact on hydrology and water resources,” Briesmoore said.
She spoke to a packed room of about 150 attendees at Thursday’s [May 21, 2026] Roaring Fork River: State of the River event hosted by the Colorado River District at the Pitkin County Library…“It’s important for people to know that this year is unprecedented . . . it’s like nothing we have ever seen before,” Briesmoore said. “Every single drop of water really, really matters. We have to think about how we are using it, and what we are going to do with very, very low water resources.”
To a room full of gasps, Briesmoore showed a graph with a star marking the 2026 winter — from October 2025 to March — high above the rest. While years including 1902, 1904, 1977, 2002 and 2018 recorded less precipitation, in terms of temperatures there’s no other year that even came close to 2026.
The Pacific Ocean is a giant climate cauldron, with a powerful heat engine that affects storms, fisheries and rainfall patterns half a world away, and scientists are watching closely to see if it’s about to boil over.
Their projections suggest the tropical Pacific is simmering toward a strong El Niño, the warm phase of an ocean-atmosphere cycle that can intensify and shift those impacts.
In a world already superheated by greenhouse gases, a strong El Niño during the next 12 to 18 months could permanently push the planet’s average annual temperature past the 1.5 degrees Celsius warming threshold enshrined in scientific documents and political agreements as a turning point for potentially irreversible climate impacts.
Climate scientists also recently published a study showing that strong El Niño events can trigger what they called “climate regime shifts,” meaning abrupt, lasting changes in heat, rainfall and drought patterns.
El Niño is one of the planet’s biggest natural release valves for ocean heat. The venting starts with periodic shifts of swirling ocean currents and winds over the Pacific. That causes huge stores of tropical ocean heat to surge eastward from the Western Pacific Warm Pool, roughly between Australia and Indonesia, northward to Japan. Those tropical seas are by far the warmest ocean region on Earth, and span an area four times as large as the continental United States.
When that ocean heat spreads across the equatorial Pacific, it spills into the atmosphere in pulses that tilt weather patterns, reroute powerful high-elevation winds, raise global temperatures, bleach coral reefs and disrupt fisheries and ocean ecosystems. The effects hit continents as well, intensifying rainstorms and flooding in some regions, while amplifying extreme heat, drought and wildfires in others.
In 2015, heat from the tropical Pacific helped raise the global annual average temperature irreversibly past 1 degree Celsius above the pre-industrial baseline. And in 2024, Earth experienced the hottest year recorded in human history, aided by another El Niño boost.
Even a moderately strong El Niño during the next 12 to 18 months could drive the average global temperature to about 1.7 degrees Celsius above the preindustrial level, climate scientist James Hansen told Inside Climate News. Hansen doubts the world will meaningfully cool back down to below the 1.5 degree Celsius mark after the El Niño fades.

Passing that threshold may not be like falling off a climate cliff, but it’s definitely the point when the edge starts crumbling, with rapid changes to relatively stable systems of forests, water, rain and temperatures that have sustained people and ecosystems for millennia.
Even below the 1.5-degree Celsius threshold, California reservoirs no longer fill in some years and overflow with extreme rainfall in others. Coral reefs from Australia to the Caribbean have bleached beyond recovery and vast tracts of forests burned up in megafires. Traditional crop calendars don’t align with seasons. Deadly nighttime heat rises in cities, killing vulnerable people in apartments that never cool.
“Super El Niño” Seen as Game Changer
Climate impacts amplified by strong El Niños keep hitting the same vulnerable regions, may be more widespread than previously thought and can persist long after the tropical Pacific cools, according to an El Niño study published December 2025 in Nature Communications.
The study concluded that “super El Niños” are not just passing weather events, but more like climate shocks that can push parts of the Earth system into new states, co-author Jong-Seong Kug wrote in an email.
The study’s definition of a super El Niño is when the sea surface temperature anomaly in the tropical Pacific “exceeds 2 standard deviations above normal”—not an ordinary fluctuation, but more of a systemic warning sign.
The impacts are clustered in areas known to be sensitive to long-distance climate connections and regions “that are already prone to climate regime shifts,” wrote Kug, a climate researcher at Seoul National University in South Korea.
There are only three super El Niños on record: in 1982-83, 1997-98 and 2015-16. All of them contributed to regime shifts in regional ocean temperatures, leading to unprecedented marine heat waves that destroyed or damaged coral reefs and caused mass die-offs and starvation among many marine organisms, from starfish to seabirds and marine mammals.
Those impacts, as well as changes in drought and extreme heat over land areas, persisted for years and could shift some regional patterns for decades, according to the study.
Kug said the main “regime-shift hotspots” in oceans include the central North Pacific, the southeastern Indian Ocean, the southwestern Pacific and the Gulf of Mexico, areas where globally linked atmospheric connections “can strongly perturb the ocean surface and, in some cases, help anomalies persist.”
Kug said the study identified super El Niño regime shifts in East Africa and the Maritime Continent—the island-rich region between the Indian and Pacific Oceans around Indonesia, Malaysia and Papua New Guinea.

April 26, 2026
It’s time to bring in a mediator to handle the prolonged dispute over managing the Colorado River between the Upper and Lower Colorado River Basin states, representatives of the four Upper Basin states say.
“The proposal for mediation attempts to address the current deadlock between Upper Basin and Lower Basin approaches and begin to deal with the basin’s dire hydrologic conditions.” said the Upper Colorado River Commission, which represents Colorado, New Mexico, Utah and Wyoming.
“The commissioners believe a structured mediation process can support authentic negotiations and collective action to address the Basin’s operational challenges,” the commission said in a news release last week.
The request for a mediator to handle this dispute follows about two years of fruitless negotiations among the various state representatives. There have been several major sources of dispute, but the biggest one has been over how the two basins should split the cuts in river water use that would be needed to bring human demand in line with shrinking supply…The Upper Basin states’ request comes not long before the U.S. Bureau of Reclamation is supposed to announce its plan for managing the river, in the absence of an agreement among the basin states. A new plan is necessary because the river’s current operating guidelines expire Sept. 30…
The request for mediation also comes as the river’s condition continues to deteriorate. Hot, dry weather has held down water flows in the river for most of the year, and there’s a risk that spring-summer runoff into Lake Powell will be the lowest on record since Lake Powell started filling in the 1960s.
China’s rapid rise in science has hit a milestone. The country’s investment in research and development has reached parity with – and by purchasing power measures has surpassed – that of the United States, according to a March 2026 report from the Organisation for Economic Co-operation and Development. Both nations have crossed the US$1 trillion threshold on research spending.
In contrast, China had previously spent little to nothing on research and development. Some estimates show that China was among the lowest research spenders worldwide in 1980.
The most recent reports showing that China is now outspending the U.S. on scientific and technological research is a turning point worth understanding clearly because, historically, global leadership in one sector – including technology and warfare – feeds into others. U.S. dominance is in question.
In 2024, China overtook the United States in total scientific publications – the first time any nation has displaced American dominance since the U.S. itself surpassed the United Kingdom in 1948. Researchers found that China overtook the United States in scientific output even earlier. That same year, China pulled ahead in the Nature Index, which tracks publications in the world’s most selective scientific journals, posting a 17% advantage over the U.S. in outlets long considered the gold standard of scientific excellence.
Given these milestones, it’s possible to argue that China is quickly taking the lead in global science and technology. These are not isolated data points. They mark a structural shift in where the world’s scientific frontier is being built.
More science is good – the problem lies elsewhere
China’s ascent is, in one sense, good news. More knowledge, generated by more researchers across more institutions, expands the global pool of discovery from which everyone can draw. The world benefits when science thrives.
The problem is not that China is investing, but that the U.S. is not.
First, the U.S. is divesting from basic, open science. Federal R&D spending in the U.S. peaked in 2010 at roughly $160 billion and fell by more than 15% over the following five years. Federal investment in research and development has been in a long, slow slide – from a peak of 1.86% of gross domestic product in 1964 to about 0.66% in 2021.
The federal government is no longer the largest spender in R&D: It funded about 40% of basic research in 2022, while the business sector performed roughly 78% of U.S. R&D. While not a problem in itself, industry has simultaneously withdrawn from open scientific publication over the past four decades, shifting from research toward development. The result is a shrinking pool of openly shared scientific knowledge precisely as public investment in it also contracts.
The second is the active restriction of scientific exchange: tightening access to U.S. institutions, scrutinizing international collaborations and raising barriers to foreign-born researchers. These policies, though intended as security measures, work against the openness that has historically made American science productive and attractive to global talent.
I describe this issue as an example of the stockyard paradox, in which securing research assets may weaken the very system these measures aim to protect.
Disinvestment cuts deeper than it appears
The deeper danger for the U.S. economy is that disinvestment and selective engagement in research erodes the capacity to use cutting-edge science regardless of where it is produced.
Absorbing and applying cutting-edge knowledge, whether developed in Boston or Beijing, requires maintaining research institutions and trained workforces, as well as active participation in global networks. This is not a passive process. You cannot free-ride on Chinese science if you have dismantled the institutional and human capital needed to evaluate, translate and apply it.
A nation that hollows out its research base not only falls behind but also progressively loses its ability to benefit from science, including in technologies it is already able to access.
Talent compounds the problem. The U.S. built its scientific dominance partly by being the destination of choice for the world’s most ambitious researchers. The U.S. leads the world in Nobel Prizes, but, notably, 40% of the Nobel Prizes in chemistry, medicine and physics that were awarded to Americans since 2000 were won by immigrants. The flow of foreign talent is not guaranteed. It follows opportunity, funding and openness.
China’s milestone in research funding arrives at a moment when the U.S. is deciding whether to maintain its scientific leadership.
Scientific infrastructure does not decline gradually and recover on demand. Doctoral scientists represent a decade or more of training; tacit laboratory knowledge lives in working research groups, not in documents. Once talented young researchers leave the pipeline – or international talent redirects to other countries – the capacity is very hard to rebuild. Early warning signs are already visible in the U.S. system: thousands of NIH grants terminated, a collapse in international applications and an exodus of early-career scientists.
What is at stake is not a ranking. It is whether the U.S. maintains the institutional capacity – the universities, the federal laboratories, the graduate pipelines, the culture of open inquiry – that made those returns on scientific investment possible in the first place.
China’s rise did not create this decision point, although it brings it into sharp relief. Does the U.S. still want to lead in science? The Information Technology and Innovation Foundation, a nonprofit think tank, estimates that a 20% cut in federal research and development starting in fiscal year 2026 would shrink the U.S. economy by nearly $1 trillion over 10 years and reduce tax revenue by around $250 billion. Others point out that the scientific enterprise has contributed at least half of U.S. economic growth.
When I led the Bureau of Land Management under President Biden, the hardest part of my job was reassembling the agency after the first Trump administration had scattered its headquarters from our nation’s capital. The move crippled the agency—as intended.
That experience led me to understand that the current Trump administration’s unpopular plan to move the U.S. Forest Service headquarters will be every bit as destructive. It will hurt forests, wildlife and communities that rely upon our public lands and waters.
In 2020, almost 90% of the BLM employees ordered to move West chose not to, forcing them out the door. With those seasoned employees went years of wisdom and knowledge of how things are supposed to work, of how to deliver for the American people.
Today’s Forest Service plan goes farther, aiming to close regional offices and shutter dozens of the agency’s research centers, as we face what some say will be a horrific wildfire season.
The Forest Service and the BLM combined manage 20% of our country’s lands and waters. These public lands, the places we camp, hike, watch birds, hunt and simply wander in nature, are truly one of America’s best ideas. For Westerners, they are a deep part of our identity.
There is a reason Forest Service headquarters are based in Washington, DC. It’s where our nation’s leaders work. Believe me, I did not want to move to the capital from my home in Montana to run the BLM, but to be able to fight for Western people and places, I had to go to the seat of our nation’s power.
I was often in the Interior Secretary’s offices. I frequently walked to work with the U.S. Fish and Wildlife Service director, talking through thorny problems such as how to protect wildlife while permitting transmission lines. Washington is where people manage relationships with Congress, where budgets get made.
The administration says all their changes are about bringing leadership closer to where the work happens. That’s a political talking point, and it’s false.
If DOGE’s dismantling of government agencies last year provides any lesson, then cruelty and disruption are the real point. These changes aim to create chaos, deliver the administration’s stated goal of traumatizing employees, and imperil the very existence of public lands — lands that belong to all Americans. We improve the management of our forests by giving foresters the resources they need and letting them make decisions based on sound science and collaboration, not by gutting their agency.
Over the course of the last year, the Forest Service forced or coerced roughly a quarter of its approximately 30,000 employees to leave. In this latest round of engineered chaos, thousands of people will be reassigned and ordered to move. If BLM history is any guide, almost all will leave their positions rather than uproot their families. The agency could soon be left with roughly half its former ranks.
Think of your job. Now, think of half of your colleagues gone. Would your organization be able to recover from the loss and demoralization to do its work?
There are inevitable repercussions to this radical attack on our public land management agencies: Campgrounds will close. Trails won’t be maintained. High fuel loads near communities will go unaddressed. Wildfires will become even harder to fight. More sawmills will close. The health of our land, waters and wildlife will decline. With things going wrong on the ground, some will demand that these lands be transferred to states or sold to private industry.

That’s exactly what the people in power today want. The choice of Utah for the Forest Service headquarters—home to Senator Mike Lee, who leads the charge on public land selloff, as well as to the state that is suing to try to take over millions of your public lands—reveals the administration’s true agenda.
The inevitable does not need to happen. There is one power to stop our public lands from being mismanaged to the point of selloff: It’s the outrage of the American people.
Americans overwhelmingly support public lands and want future generations to enjoy the freedoms found in them. Our public forests, rivers and deserts deserve to be treated better, and the federal land managers who work tirelessly deserve better. It’s up to us to demand it.

With a historic drought hitting the Colorado River basin, the U.S. Bureau of Reclamation is making preparations to slow releases from the river’s largest reservoir while increasing withdrawals from an Upper Basin reservoir.
“Given the severity of the risks facing the Colorado River system, it is imperative that we take action quickly to protect a resource that supplies water to 40 million people and supports vital agricultural, hydropower production, tribal, wildlife and recreational uses across the region,” said Andrea Travnice, the Bureau of Reclamation’s assistant secretary of water and science in a Friday, April 17 news release…
As a result, the Bureau of Reclamation is anticipating that inflow to Lake Powell will be 29% of the historical average, which it reports is one of the lowest on record. If water levels fall below a certain elevation — below 3,490 feet or roughly 15% of its capacity — it can impact operations, regional power and water supplies as well as reduce hydroelectric power generation. The Bureau is projecting it could hit this minimum power pool level by August. As of April 19, Lake Powell and Lake Mead were 24% and 32% full, respectively.

Water starts to fill Chimney Hollow Reservoir in Larimer County on Tuesday, April 21. Scott Franz/KUNC

April 22, 2026
At 8 a.m. Tuesday, there was only silence and the occasional crunch of rocks as a dozen people in orange vests waited in a moonlike landscape beneath a 350-foot-tall dam near Loveland.
“Ninetey seconds,” a worker called out.
Moments later, it sounded like a waterfall suddenly roared to life as Northern Water started filling Colorado’s newest reservoir, Chimney Hollow.
“It’s pretty cool, I mean it’s something we’ve been working on for a long time, so just to see it for real, it’s pretty cool,” Chris Manley, a water quality specialist with Northern Water, said as he watched water gush from a 40-foot-tall concrete tower at the bottom of the reservoir.
By the end of the week, the initial release of 1,500-acre feet of water will rise about 30 feet above the spot Manley and a gaggle of journalists were standing on Tuesday morning.
Engineers will make sure the pipes that will funnel Colorado River water to the reservoir are functioning correctly. It will also give Northern Water a chance to study an issue with the water supply.
The reservoir’s future became murky last year after officials announced that naturally occurring uranium was found in the rock used to build the dam for the reservoir.
Manley said the uranium discovery has set the project back roughly a year. But he said it is an issue Northern Water can manage long term.

“But we’ve got to really understand the situation a lot better before we can move forward,” he said.
This week’s initial fill will provide Northern Water with a real-world test of the water quality that was only previously done in laboratories.
None of the water coming into the reservoir will be released to taps at this point. The reservoir is only being filled to about 2% of its total capacity in the coming days.
“We’ll be measuring it actually pretty frequently, to see just what is (the water) picking up as it goes up and touches the dam and starts to move some of the sediments around here,” Northern Water spokesperson Jeff Stahla said.
Northern Water officials could not provide a timeline for when water will begin reaching the dozen water suppliers who have signed up to receive it.

The reservoir project cost an estimated $500 million and has been in the planning stages for more than two decades.
Conservation groups have raised concerns about the reservoir.
“You can have a bunch of buckets, and you can build more buckets to put water on the front range,” Pelz said. “But the reality is, if the projected climate change impacts come to fruition — which all indications are, they’re coming to fruition quicker than we even thought — there’s going to be no water to fill those buckets.”
The reservoir is seeing its initial fill during historic drought conditions in the Colorado River basin.
“It’s definitely very ironic that we’re filling the reservoir in these historic drought conditions, but we’re fortunate that we had a little bit of supply left from last year,” Northern Water Operations Director Jerry Gibbens said. “It really showcases why storage is so important for our region.
Northern Water officials say the reservoir is a way to boost water security on the Front Range.
“As we’ve seen this year, water storage is such a key element of our overall water supply in northern Colorado, and this just adds another increment of that supply to a region where our water demands continue to grow,” Stahla said.

At an April 9 meeting, the Pagosa Area Water and Sanitation District (PAWSD) Board of Directors approved revisions to the district’s drought management plan. District Engineer Justin Ramsey opened discussion of the plan, which he explained was a complete rewrite of the previous plan and was adopted in 2020 with a stipulation that it be reexamined in 2026. He added that the district also had to implement the plan in 2025 due to dry conditions, which gave additional insights into how the plan functions. He explained that he recently reconvened the committee that drafted the plan, including PAWSD board members, water experts in the community, business owners and other community members. Ramsey stated that, although there were some changes recommended to the plan, it has, overall, been highly successful. He explained that the drought stages outlined in the plan are entered based on triggers, which are different depending on the time of year.
Early in the year, he stated, the triggers are the snowpack in the mountains, measured by the amount of snow water equivalent (SWE) at the U.S. Natural Resources Conservation Service SNOwpack TELemetry Network (also commonly known as SNOTEL) station on Wolf Creek Pass and the date when the district’s water supply is cut off on Four Mile Creek due to other senior water users diverting water…If specific SWE levels or a call on Four Mile do not occur by specific dates in the spring, the plan shifts to a different set of drought triggers based on water levels in Lake Hatcher (one of PAWSD’s primary reservoirs), water flows in the San Juan River and the drought stage for Archuleta County designated by the National Integrated Drought Information System (NIDIS). He explained that the amount of water in Lake Hatcher is weighted the most heavily, with flows in the San Juan being the next most influential factor and drought designation being the least. He added that the different drought stages come with different drought surcharges and water rate adjustments…He explained that the first drought stage (voluntary drought) aims to cut water use by 10 percent, while the most severe drought stage (stage four) is intended to cut water use by 50 percent.
On April 22, the Pagosa Area Water and Sanitation District (PAWSD) entered stage one drought under its drought mitigation plan, imposing new restrictions on irrigation and rate multipliers for high water use. The district’s drought plan calls for Conservation Service SNOwpack TELemetry Network (SNOTEL) site reaches zero between April 17 and May 1. SWE fell to zero on April 22, triggering stage one drought, according to PAWSD District Engineer Justin Ramsey. During drought stage one, irrigation is permitted only between 6 p.m. and 9 a.m., and residential customers who use more than 5,000 gallons of water a month will have a 1.25 times rate multiplier applied to their water bills. According to the PAWSD website, the imposition of this multiplier will begin to impact customer bills received in May, although the irrigation restrictions will start immediately. The plan notes that gardens may be hand watered using a hose or drip irrigation.

This year’s historic winter of low snow might feel novel. But recent years give some insight into just how dry the West’s most important river system can get. This season’s scant snowpack is melting rapidly, and turning up memories of other notably dry years.
Prolonged drought conditions and warming temperatures since 2000 have produced severe single-year droughts in 2002, 2012, 2018 and 2020 in the river’s headwaters states of Colorado, Wyoming and Utah. As severe drought years continue to put the Southwest’s water infrastructure to the test, communities in the region are grappling with how best to understand and adapt to a changing climate.
2002 stands as the worst drought on record for the Colorado River, measured as the flow into one of its biggest reservoirs, Lake Powell on the Utah-Arizona border. It’s possible 2026 could break that record. Back then the year acted as a wake-up call to the region’s water leaders, spurred important policy changes, and reshaped attitudes around conservation.
We asked Colorado River experts Eric Kuhn, Jeff Lukas and Jim Lochhead to share five important takeaways from the 2002 drought, and what to know as we enter the warmer, drier months of 2026.
1. Reservoirs have memory
Reservoirs act as batteries for water availability, charged by inputs such as snowmelt, streams, rivers and precipitation.
“What you did two or three years ago can affect your water supply now,” said Eric Kuhn, former general manager for the Colorado River Water Conservation District. “So in a good year, if you are conserving, you are actually helping the system out for the next drought.”
The 2002 drought prompted municipal utilities to rethink their reservoir usage.
“Water managers and agencies have absorbed several lessons from 2002, including holding something back. They’re operating the reservoirs a little differently,” said Jeff Lukas, an independent climate and water researcher who has lived on Colorado’s Front Range for 40 years.
By conserving reservoir water, municipal utilities can maintain water storage for less abundant water years of the future. But as dry conditions have dogged the entire Colorado River basin for more than a quarter-century, the system’s buffer is gone.
“The biggest issue is that Lake Powell and Lake Mead were relatively full in 2002,” Kuhn said. Now, both Lake Powell and Lake Mead are at critically low levels, and the water scarcity is increasing the likelihood of multi-state litigation.
In 2002, drought was dealt with on a local level; water utilities were not thinking about drought in terms of the entire river system, but instead how to regulate municipal water use. This year’s dry conditions are pushing the whole region to the brink.
2. Conservation can make a big difference, if it is mandatory
Individual contributions to water conservation, adhering to local outdoor watering restrictions for example, can make a difference. Prompted by the 2002 drought, a 2004 University of Colorado study aimed to measure the effectiveness of water restrictions put in place by water providers on the state’s populated Front Range.
The study followed municipal water providers Thornton, Aurora, Westminster, Fort Collins, Boulder, Louisville, Lafayette and Denver Water, comparing 2002 usage to average water usage in 2000 and 2001. Researchers determined that water restrictions are most effective when mandatory. Mandatory restrictions in Lafayette reduced water usage by as much as 53%, according to the study.
The same study found that under mandatory restrictions, savings of expected water use per capita was as successful as 56%, while voluntary restrictions only measured up to 12%.
Outdoor watering represents a big slice of a city’s water budget, and 2002 showed utilities that in times of crisis people can rein in their use.
“Everyone should realize that they can make a small contribution to the solution,” Kuhn said. “Even though their individual contribution might be miniscule, when you add up all their neighbors and other people, it’s not miniscule. It’s very, very big.”
Watering a lawn once or twice a week, and not during peak hours, is a practical way to conserve water while keeping grass alive.
3. This is not a one-off year
It’s easy to shrug off a dry year and hope for wet weather’s return. But the long-term trends are concerning.
“This is really the 26th year of extreme drought,” said former Denver Water CEO Jim Lochhead. On a larger scale, the seven Colorado River basin states—Arizona, California, Colorado, Nevada, New Mexico, Utah and Wyoming—have been preparing for worsening drought conditions since the shock of 2002. But river policy hasn’t kept pace with the aridification, leaving the region’s largest reservoirs at near record lows.

“This has been a slow moving train that I think the states have known was coming, and they have frankly failed to do anything about it,” said Lochhead, who also represented the state of Colorado amid interstate Colorado River negotiations in the 1990s and early 2000s.
The Colorado Climate Center anticipates droughts to increase in severity and frequency, a trend that is only expected to continue in Colorado and across the Southwest as warming temperatures upend the water cycle.
“We should be managing and thinking about water, using water, as though it were always a drought,” Lukas said.
4. Communities have more practice dealing with drought, but still struggle
Drought conditions in 2002 led some municipal water utilities to organize and create incentives for conservation, and transformed the urban landscape, swapping grass for more drought-tolerant plants. Those water restrictions allowed municipal water providers to curb water demand while steadily growing in size. However, there is still room for improvement in disproportionately affected communities.
According to Lochhead, urban areas need to prioritize heat reduction in neighborhoods that have fewer trees in order to lessen the impacts of drought and warming temperatures. Using scarce water supplies to encourage tree-planting and increase shade should remain a priority.
“I think we need to work with those communities to enhance some landscaping,” Lochhead said. “Whether it’s the homeless population, whether it’s just kids that are out, whatever it may be, those areas are where they’re pretty hard hit by heat.”
Farmers and ranchers are used to riding the highs and lows of western weather. But extremely dry years like 2002, and now 2026, can push their operations to the limits.
“This is going to be a really tough year,” Lukas said. “You’re going to have a lot of people selling off their herds and taking insurance out because of low crop yields.”
The majority of Colorado’s annual water supply is used for irrigation, so any proposed restrictions can be costly for the agricultural community. “There are going to be a lot of farms and ranches that just can’t operate because they don’t have any water,” Lochhead said. “There are going to be some significant economic consequences.”
5. Stay aware, even if things seem bleak
For Lukas, this year and its predecessors test our expectations about what nature can provide.
Even in periods of prolonged drought, there are wet years. “Judging from history, that tends to put everyone back on their heels, a little complacent,” Lukas said, but maintaining water storage relies on year-to-year vigilance, not complacency.
Another primary concern during drought years is wildfire. With less moisture in the soil, dry vegetation acts as fuel for wildfire, which becomes harder to contain under hot and dry conditions.
“I worry a lot less about municipal water supply than I do about wildfire,” Lukas said. Many of Colorado’s notably dry years have also recorded severe and destructive wildfires.
It comes at no surprise that worsening drought falls in line with worsening wildfires. “Climate change is delivered to people through changes in the hydrologic cycle,” Kuhn said, so being aware of water usage now is just as, if not more important as it was in 2002.
