12 USGS Streamgages
Skagit River flows and levels
Skagit River is gauged at 12 USGS streamgages in Washington, each tracked by Rivermatics. It feeds the North Fork Skagit River. The gauged reach falls about 475 feet, from 494 feet down to 19. Rivermatics issues a daily machine-learned 14-day flow outlook at 4 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
- How many gauges are on the Skagit River?
- Rivermatics tracks 12 USGS streamgages on the Skagit 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 Skagit River?
- Yes, at 4 of the 12 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.
- Can I use Skagit 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.
