Snow-water equivalent by basin and the seasonal runoff outlook for Utah's rivers, translated into what it means for fishing — early or late runoff, high or low summer flows, and which waters hold up best. Updated daily through the snow season.
Basin SWE vs. median — water year 2026
Average across the Utah basins we track, in inches of snow-water equivalent.
Runoff forecasts are the projected seasonal streamflow volume versus the long-term average, issued monthly January–June. Only rivers with a published forecast point show one.
Snowpack percentages compare current basin snow-water content to historical norms; the Utah figure is statewide, not specific to any one basin. Snowpack varies with elevation and aspect — treat basin figures as a guide. Updated Jun 14, 2026.
