Washington state received more precipitation than normal this past winter. By spring, the mountains held barely half the snowpack they should. On April 8, Gov. Bob Ferguson declared a statewide drought, setting up a summer of hard choices for farmers, cities, and the rivers that salmon depend on to survive.
The problem was not a lack of moisture. It was the wrong kind.
A wet winter that didn’t stick
Between October 2025 and February 2026, Washington received 104% of its normal precipitation, measured against the 1991-2020 baseline that NOAA uses for its U.S. Climate Normals. By that standard, the state had a wet winter. But warmer-than-average temperatures turned much of that moisture into rain rather than snow, and the consequences became impossible to ignore when the spring snow survey came in.
On April 1, 2026, statewide Snow Water Equivalent (SWE) stood at just 52% of the 1991-2020 median, according to the USDA Natural Resources Conservation Service’s water supply outlook report. SWE measures how much liquid water is locked inside the snowpack. At 52%, the state’s mountain reservoirs of frozen water are roughly half of what communities, irrigators, and hydropower operators count on for the dry months ahead.
The distinction between rain and snow matters because of timing. Rain that falls in winter runs off quickly through streams and rivers, reaching Puget Sound or the Pacific within days or weeks. Snow, by contrast, stores water at elevation and releases it gradually through spring and early summer, feeding reservoirs and streams precisely when demand is highest. When that storage mechanism fails, even a wet winter can leave the state functionally dry by July.
The Washington Department of Ecology noted in its February water supply update that high winter streamflows, driven by rain rather than snowmelt, can mask the severity of a snowpack deficit. Rivers looked healthy through the winter because rain was pushing water downstream in real time. But that water is already gone. It will not be available in late summer when irrigation districts need it most and when salmon require cool, flowing streams to survive.
What the drought declaration does
The statewide drought declaration, documented in the Department of Ecology’s official notice, is not a forecast or a warning. It is a binding state action based on observed conditions, and it activates a specific set of emergency tools.
Those tools include fast-tracking temporary water right transfers so that water can move to where it is needed most, providing financial assistance to communities and irrigators facing shortages, and coordinating conservation messaging through local utilities and irrigation districts. The order covers all of Washington, signaling that the snowpack problem is not confined to a single watershed or region.
Ecology Director Laura Watson framed the declaration as a call for immediate conservation. The agency’s announcement made clear that despite water-year-to-date precipitation running near or above normal across most basins, the low snowpack creates a serious supply gap once summer demand peaks.
Washington has been here before. In 2015, a similarly warm winter produced a statewide drought emergency despite near-normal precipitation totals. That year, the Yakima Basin saw significant curtailment of junior water rights, and some farmers fallowed fields rather than risk planting crops they could not finish irrigating. The 2015 experience prompted the state to invest in drought preparedness, but the underlying vulnerability remains: Washington’s water system is built around snowpack as a natural reservoir, and when snow doesn’t accumulate, no amount of rain can substitute for it.
Where the picture is still incomplete
The statewide numbers tell a clear story, but the basin-by-basin details that will determine who actually runs short this summer are still emerging.
Station-level data from the NRCS interactive snow map show wide variation across individual monitoring sites. Some stations recorded near-record-low SWE, and higher-elevation sites that typically act as the last line of cold storage are among those with the steepest deficits. But translating those station readings into precise streamflow forecasts requires additional modeling that, as of late May 2026, has not been fully published for the current water year.
Federal agencies that manage major water systems in Washington, including the Bureau of Reclamation (which operates the Yakima Project and parts of the Columbia Basin Project) and the U.S. Army Corps of Engineers, have not released detailed public statements about how they plan to adjust deliveries or reservoir operations in response to the 52% SWE figure. Tribal nations, which hold senior water rights on several key river systems, have likewise not issued public positions on the drought declaration or on potential curtailment scenarios.
Agricultural yield forecasts tied to the low snowpack have not appeared in available public reports. For a state where irrigated agriculture generates billions of dollars annually and where crops like apples, hops, potatoes, and hay depend on reliable summer water, the financial stakes are enormous but not yet quantified. Hydropower generation projections, which affect electricity prices across the Pacific Northwest, are similarly uncertain.
Many cities rely on a mix of mountain reservoirs, groundwater, and regional wholesale supplies. Without updated modeling, it is not yet clear which municipal systems will face mandatory restrictions, which can get by with voluntary conservation, and which may be buffered by stored water from previous wet years. Those distinctions will matter for households and businesses as the season progresses.
What this winter may be telling us
The role of long-term warming in shifting precipitation from snow to rain is well established in climate science. Research published over the past decade has consistently shown that the Pacific Northwest is losing snowpack as winter temperatures rise, with lower-elevation snow zones shrinking the fastest. But Washington-specific analysis connecting this particular winter’s warm temperatures to the broader trend has not been released in the current reporting cycle.
Whether 2026 was an isolated warm spell or part of an accelerating pattern matters enormously for infrastructure planning and water rights policy. If warm, rain-dominant winters become more frequent, the state’s entire water management framework, which depends on snowpack as free, high-elevation storage, will need to be rethought. That could mean expanding reservoir capacity, investing in managed aquifer recharge, or restructuring water rights to reflect a supply curve that peaks in winter rather than late spring.
For now, the most defensible reading of the evidence is straightforward: Washington is entering a high-risk summer with roughly half the stored snow it normally relies on. The verified data points (near-normal winter precipitation, far-below-normal snowpack, and a formal statewide drought declaration) support a clear conclusion that water users should prepare for shortages. The unresolved questions around allocation, economic loss, and long-term climate trajectory will determine how severe those shortages become and who bears the brunt of them.
As additional modeling and agency guidance emerge over the coming weeks, they will either confirm that this year’s drought is primarily a consequence of unusual warmth in an otherwise variable climate, or they will strengthen the case that Washington’s water systems must adapt to a future in which wet winters no longer guarantee secure summer supplies.
