California Snowpack & River Runoff

Snow-water equivalent by basin and the seasonal runoff outlook for California'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.

California's snowpack is running thin this year — the statewide figure of 0% of normal means runoff peaked early and summer flows will thin out faster than usual. The higher-elevation freestones won't fish for long; tailwaters and spring creeks will carry more of the season.

If you're planning trips this year, bias toward tailwaters with cold dam releases and spring creeks that aren't snowmelt-driven. Smaller freestones in the lower elevations may warm into marginal water by mid-summer.

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 California figure is statewide, not specific to any one basin. Snowpack varies with elevation and aspect — treat basin figures as a guide. Updated Jul 16, 2026.
