Klickitat River flows and levels

Klickitat River is gauged at 3 USGS streamgages in Washington, each tracked by Rivermatics. The mainstem runs about 93 miles (149 km) from headwaters to outlet. It drains into the Columbia River system. Drainage area at the gauges ranges from 151 square miles at Klickitat River above West Fork near Glenwood, WA up to 1,297 at Klickitat River near Pitt, WA. Rivermatics issues a daily machine-learned 14-day flow outlook at 2 of them.

Gauges on this river, upstream to downstream

Ordered by drainage area, which is how far down the river each gauge sits. April and July figures are long-term median daily flows for that month from the USGS record — historical normals, not a forecast and not today's reading.

Common questions

When does the Klickitat River run highest?
May, on the long-term record at Klickitat River near Pitt, WA — the furthest-downstream gauge Rivermatics tracks on this river. Median daily flow there is about 2,358.4 cfs that month, against 724 cfs in September, the lowest. Upstream gauges peak on their own schedule; the table on this page gives April and July for each.
How many gauges are on the Klickitat River?
Rivermatics tracks 3 USGS streamgages on the Klickitat River, across Washington. Each has its own page with the site's full flow record and monthly normals. The river may carry other gauges that publish neither daily values nor discharge statistics; those are not tracked here.
Is there a flow forecast for the Klickitat River?
Yes, at 2 of the 3 gauges. Rivermatics trains a machine-learned model — a temporal-fusion transformer — on each basin's observed flows, weather and snowpack, and issues a daily outlook reaching 14 days ahead: a median estimate inside a confidence band, not a single number to bet on. Every forecast is scored against days the model never trained on, and that track record is published on each gauge's live screen.
What river system is the Klickitat River part of?
The Klickitat River drains into the Columbia River system — it is a tributary somewhere in that chain, following the flowpath down to its terminal river. Rivermatics builds this from the USGS/geoconnex reference-mainstem network rather than from names.
Can I use Klickitat River data for flood or safety decisions?
No. Rivermatics provides estimates, not guarantees, and the readings and forecasts here may be delayed, inaccurate, or wrong. Do not use them for navigation or for any safety, rescue, or emergency decision. Check the National Weather Service and USGS directly, and use your own judgment.
