At the end of February, snowpack was less than half its normal level across nine western states<\/a>. Colorado, Oregon and Utah have reported their lowest statewide snowpack since the early 1980s<\/a>, the farthest back records go. <\/p>\n\n\n\n

In their latest update, the NOAA Colorado Basin River Forecast Center<\/a> reported today that snowpack in the Upper Basin is 2.5 inches lower than last year due to warmer temperatures. One main takeaway on their webinar: \u201cEverywhere has extremely poor snowpack conditions.\u201d<\/p>\n\n\n\n

Conditions are especially worrisome in Oregon, where snowpack is not only at a record low, but a full 30% lower than the previous record<\/a>. In my home state of New Mexico, we are also on track for a statewide record low snowpack,<\/a> which has us biting our nails about possible wildfires<\/a> as the spring winds ramp up in the Land of Enchantment.<\/p>\n\n\n\n

This so-called \u201csnow drought\u201d is exactly what climate and water scientists have been telling us to brace for: Extreme swings in weather, and consequently far less certainty about our water supplies, are now fundamental facts of life that we must learn to live with in the West.<\/p>\n\n\n\n

Unfortunately, these drier conditions also are marching eastward as places like South Dakota<\/a> and even New Jersey<\/a> experience drought warnings. For this blog, I thought I\u2019d focus on the two regions where I\u2019ve spent most of my career: California and the Colorado River Basin.<\/p>\n\n\n\n

The NOAA Colorado Basin River Forecast Center reported snowpack at or near record lows (as measured by snow water equivalent, or SWE) at many SNOTEL locations in a webinar Friday, as pictured by the red and orange dots above.<\/figcaption><\/figure>\n\n\n\n

California: Hardly out of the woods<\/strong> <\/h2>\n\n\n\n

California may be the poster child for extreme weather swings. Although known for its deep droughts, California is surprisingly 100% drought free right now. The state ended 2025 feeling pretty good about its Sierra Nevada snowpack, a \u201cfrozen reservoir\u201d that serves about 30% of the state\u2019s water needs. But that shifted into anxiety with little snow in January, followed by a massive February storm that spawned the deadliest avalanche in the country since 1981<\/a>.<\/p>\n\n\n\n

\"U.S.<\/a><\/figure>\n\n\n\n

While the pendulum swings wildly from one extreme to another, this increased volatility itself is one clear trend. Another important trend is the shift from snow to rain at higher altitudes<\/a> because of warmer temperatures. This reduces the amount of water held in the mountain snowpack \u2014 the natural reservoir that gradually melts and releases water to fill rivers and      reservoirs in the spring and summer. <\/p>\n\n\n\n

So how do we respond to these snowpack trends? In California, the year-to-year uncertainties about snowpack highlight the importance of having policies and programs like the Sustainable Groundwater Management Act<\/a> and Multibenefit Land Repurposing Program<\/a>, which are helping the state better leverage the amazing natural infrastructure of our groundwater basins to help us weather the extreme swings between drought and storm and partially offset the shrinking snowpack. Sustained funding to support large-scale land repurposing and groundwater sustainability agencies is essential to help communities navigate through this difficult transition of reduced groundwater pumping and a smaller agricultural footprint.

Because these weather extremes also include severe flooding, it\u2019s also encouraging to see the growing interest and energy at the state and local levels, including communities and farmers, to safely tap flood flows for groundwater recharge.<\/p>\n\n\n\n

Colorado River Basin:<\/strong> On the brink<\/strong><\/h2>\n\n\n\n

While California digs out of February\u2019s snowmageddon, snowpack across the Colorado River Basin sits at record lows as March begins \u2014 a pivotal time as the seven states that rely on      river struggle to reach agreement over new guidelines for sharing its shrinking river supplies     .

In the Upper Colorado River Basin<\/a> (Colorado, New Mexico, Utah and Wyoming), snowpack is the lowest on record<\/a> for this point in the water year (dating to 1982), signaling a high risk of reduced runoff, poor reservoir inflows and wildfires. Lake Powell and Lake Mead, the Colorado River\u2019s two key reservoirs, have already plummeted to historic lows, at 26% full and 34% full, respectively. <\/p>\n\n\n\n

\"Glen
Unless action is taken, Lake Powell is forecasted to fall to minimum power pool<\/a> this year, meaning there will not be enough water to generate electricity at Glen Canyon Dam (above).<\/figcaption><\/figure>\n\n\n\n

It\u2019s important to remember that, unlike most of California\u2019s reservoirs, these two don\u2019t refill every year or even every other year. These low levels represent a decades-long trend and have already led to reductions for Arizona, which gets 36%<\/a> of its water from the Colorado River, and Nevada, which relies on the Colorado River for 90%<\/a> of the water in the southern part of the state.<\/p>\n\n\n\n

Given the dismal snowpack in the Upper Basin, the levels in these key reservoirs will almost certainly continue to slide, worsening the water supply risks to the people, <\/ins>economies, and ecosystems across the Basin States and in northwest Mexico.     <\/p>\n\n\n\n

Taken together, the snowpack trends and reservoir levels are a flashing red warning sign that the Colorado River Basin\u2019s condition is more than a temporary drought cycle. Even if the pendulum swings back to the side of short-term rain or snow, no \u201cmiracle March\u201d or even a few \u201cwet years\u201d are going to turn the tide.<\/p>\n\n\n\n

The basin is fundamentally drier than when its waters were apportioned among the states more than a hundred years ago. And the soon-to-expire Interim Guidelines<\/a> are clearly not up to the task of thoughtful response to this new reality. We need new operating guidelines that move the basin beyond recurring crisis management, as outlined by conservation groups, including EDF, in a joint comment letter<\/a> to the Bureau of Reclamation on the draft environmental impact statement (EIS) for new Colorado River guidelines. These guidelines should enable durable, flexible management options that embrace our new understanding of the reality of the river.<\/p>\n\n\n\n

Turning crisis into action<\/strong><\/h2>\n\n\n\n

Simply put, the Colorado River Basin must adjust to living with less water. That is a central message reflected in the Draft EIS comments \u2014 and one that extends beyond the Colorado River to much of the western United States.

More than a decade ago, at the height of the 2012\u20132016 drought, California enacted the Sustainable Groundwater Management Act (SGMA), a once-in-a-century policy that has forged a new, more sustainable path for this critical water supply.<\/p>\n\n\n\n

The urgency of today\u2019s dry conditions across the West, particularly in the Colorado River Basin, presents a similar urgent need for historic, forward-looking action. We can\u2019t afford to let this moment of decision pass.<\/p>\n\n\n\n
