Snowy savings accounts are disappearing in the West

Winter in the western U. S. used to work like a natural savings account for water. Snow piled up in the mountains during cold months, then slowly melted to fill rivers and reservoirs when summer arrived. But the winter of 2025-26 broke the old rules. Record warmth turned what should have been snow into rain, especially at lower elevations. By April 1, California’s snowpack sat at just 18% of normal. Even places that got decent snowfall saw it melt too soon because of unseasonably warm spells. This isn’t just a one-year fluke. Scientists have warned for decades that rising temperatures would shrink snowpack. Warmer air shifts the rain-snow line uphill, leaving less mountain area to hold winter snow. The result? Rivers now fill up earlier in the year, often in winter when water isn’t as useful. Instead of a big spring melt peak, streams have smaller, scattered surges. That’s bad news for summer, when farms, cities, and wildlife really need the water.Nowhere feels this shift more than the Colorado River Basin. Over 40 million people and millions of acres of farmland depend on its water, but the river is running low. Forecasts for spring 2026 suggest runoff into Lake Powell could be among the lowest in decades—nearly as bad as the drought years of 2002 and 2021. With reservoirs already strained by 20 years of overuse, the situation is precarious. States are struggling to agree on new water-sharing rules, and the lack of snowpack makes those talks even harder. The bigger picture is clear. Temperature now matters more than rain or snowfall. A year with normal precipitation can still end in drought if most of it falls as rain or melts too early. That means less water for summer, drier landscapes, and higher wildfire risks. The western U. S. is getting a preview of a future where water doesn’t follow the old seasonal rhythm. Reservoirs may need smarter management to store early runoff and save it for later. But one thing is certain: the way water moves through the West is changing—and fast.
