Snow Water Equivalent in Western Basins - Interactive Graphs

NRCS SNOTEL Snow Water Equivalent

Dataset Tabs Default Display


Generate graphs that show cumulative snow water equivalent in river basins in western states of Alaska, Arizona, California, Colorado, Idaho, Montana, New Mexico, Nevada, Oregon, Utah, Washington, and Wyoming.

How are these data collected?

A network of Snow Telemetry sites—called SNOTEL—estimates snow water equivalent across basins by weighing the amount of snow that lands on pressure-sensitive snow pillows at stations across the west. Additional measurements come from automated stations and stations where people take manual measurements of snow.
