Westwide SNOTEL Snowpack
The whole Western U.S. in one view: every major basin shaded by how its snow water equivalent compares to the 1991–2020 normal.
How to read it: green/blue basins are at or above normal snowpack; orange/red are running below normal for the date. Maps come straight from the USDA NRCS National Water & Climate Center and reflect the most recent reporting (typically a 1–2 day delay).
