Idaho is experiencing a historic snow drought with the lowest snowpack on record, signaling potential future challenges for water management in the state. Alejandro Flores, a professor at Boise State University, called it a 'triple whammy' with warm temperatures and low precipitation leading to an early snowpack maximum in late March, much earlier than the usual early April timeframe.

Why it matters

Idaho's water management system heavily relies on snowpack, which is becoming much less reliable due to climate change. Researchers are concerned about how often these snow drought years will occur in the future and how the state will need to adapt its infrastructure and water management strategies.

The details

Idaho's snowpack reached its maximum level on March 30, earlier than the usual early April timeframe. Snowpack below 8,000 feet plummeted across the Western U.S., with the Yellowstone region being closer to normal. Flores cited a 'triple whammy' of warm temperatures in December and February, combined with low precipitation in January, as the key factors leading to the historic snow drought.

  • Idaho's snowpack reached its maximum level on March 30, 2026.
  • Snowpack usually reaches its maximum in early April.

What they’re saying

“'December and February were normal precipitation but very warm. January was a little bit closer to normal temperatures, although it was still warmer, but just no precipitation. And that is what really has set us back in terms of the snowpack.'”

— Alejandro Flores, Professor of Geosciences, Boise State University

“'Trying to figure out what that movement towards what some of my colleagues have called 'low- to no-snow future' means, in terms of our existing water management infrastructure and how we need to adapt,'”

— Alejandro Flores, Professor of Geosciences, Boise State University

What’s next

Flores cautioned that the weather in the next few months will dictate what happens with stream flow and runoff levels going into the summer. He suggested the bigger question is how often these snow drought years will occur in the future and how Idaho and other Western states will need to adapt their water management strategies and infrastructure.

The takeaway

This historic snow drought in Idaho highlights the growing challenges the state and the broader Western U.S. will face as climate change reduces the reliability of snowpack, a critical component of the region's water management system. Researchers are urging policymakers and water managers to start planning for a 'low- to no-snow future' and how to adapt existing infrastructure to these changing conditions.
