How does the Snoqualmie River at Duvall compare with last year?

It is 0.13 ft higher than on the same day last year, when the reading was 18.29 ft.

No. Gage height is measured from a fixed reference point chosen by the agency, so a reading of 10 ft does not mean the river is 10 ft deep.

On Oct 17, 2026, 03:30 PM PDT, the water level was 18.42 ft. Steady over the last 24 hours.

Is Snoqualmie River at Duvall rising or falling?

Steady over the last 24 hours. Down 0.39 ft over the last 7 days.

Is the level of Snoqualmie River at Duvall normal?

The agency publishes no normal range for this gauge yet, so we show the trend only.
