How long has Columbia River at the Dalles, OR been measured?
Discharge records at USGS site 14105700 begin in 1858, about 168 years, covering roughly 9,201 days of published daily values. The long record is what makes the monthly percentiles on this page meaningful.
Is there a flow forecast for Columbia River at the Dalles, OR?
Yes. Rivermatics trains a machine-learned model — a temporal-fusion transformer — on this basin's observed flows, weather, and snowpack, and issues a daily flow outlook reaching 14 days ahead: a median estimate inside a confidence band, not a single number to bet on. A companion model forecasts each day's water-temperature high and low. Every forecast is scored against days the model never trained on, and that track record is published on the live gauge screen. Open live conditions to see the current outlook.
