Oregon Snowpack & River Runoff

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

1 Oregon river tracked

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 Oregon 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.
