2 USGS Streamgages · Colorado River system
Fremont River flows and levels
Fremont River is gauged at 2 USGS streamgages in Utah, each tracked by Rivermatics. It feeds the Dirty Devil River. It drains into the Colorado River system. Drainage area at the gauges ranges from 751 square miles at Fremont River near Bicknell, UT up to 1,240 at Fremont River at Hwy 24 Ab Sandy C near Caineville, UT. The gauged reach falls about 2,228 feet, from 6,893 feet down to 4,666. Rivermatics issues a daily machine-learned 14-day flow outlook for every one 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 Fremont River?
- Rivermatics tracks 2 USGS streamgages on the Fremont River, across Utah. 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 Fremont River?
- Yes, at 2 of the 2 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 Fremont River part of?
- The Fremont River drains into the Colorado 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 Fremont 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.
