2 USGS Streamgages · Weber River system
South Fork Ogden River flows and levels
South Fork Ogden River is gauged at 2 USGS streamgages in Utah, each tracked by Rivermatics. It feeds the Ogden River. It drains into the Weber River system. Drainage area at the gauges ranges from 92 square miles at South Fk Ogden River below Causey Reservoir near Huntsville, Utah up to 137 at South Fork Ogden River near Huntsville, UT. The gauged reach falls about 310 feet, from 5,492 feet down to 5,182. 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.

|---|---|---|---|---|---|---|
| South Fk Ogden River below Causey Reservoir near Huntsville, Utah | UT | 92 | 5,492 | 73.8 | 80.9 | 14-day |
| South Fork Ogden River near Huntsville, UT | UT | 137 | 5,182 | 215.3 | 73 | 14-day |

Common questions
- When does the South Fork Ogden River run highest?
- May, on the long-term record at South Fork Ogden River near Huntsville, UT — the furthest-downstream gauge Rivermatics tracks on this river. Median daily flow there is about 354.2 cfs that month, against 36.6 cfs in December, 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 South Fork Ogden River?
- Rivermatics tracks 2 USGS streamgages on the South Fork Ogden 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 South Fork Ogden 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 South Fork Ogden River part of?
- The South Fork Ogden River drains into the Weber 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 South Fork Ogden 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.
