Columbia River at International Boundary water level

What this means

Low water at Columbia River at International Boundary: the gauge reads 97.07 ft, below normal for mid-October.

The median for mid-October is 98.75 ft, based on 26 years of readings, so the river stage is 1.68 ft below typical. On the same day last year the reading was 94.89 ft, a difference of +2.18 ft.

It is still going down, by 1.35 ft over the past 24 hours. Without real rain upstream, that is unlikely to change quickly. The 30-day range is 93.67 ft – 100.30 ft.

Fall is often low-water season on rivers, and it usually takes a few days of steady rain to change that.
