6 USGS Streamgages
Pit River flows and levels
Pit River is gauged at 6 USGS streamgages in California, each tracked by Rivermatics. It feeds the Sacramento River. Drainage area at the gauges ranges from 1,431 square miles at Pit River near Canby, CA up to 4,952 at Pit River near Montgomery Creek, CA. The gauged reach falls about 3,270 feet, from 4,270 feet down to 1,000. 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 Pit River run highest?
- March, on the long-term record at Pit River near Montgomery Creek, CA — the furthest-downstream gauge Rivermatics tracks on this river. Median daily flow there is about 5,976.5 cfs that month, against 2,662.7 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 Pit River?
- Rivermatics tracks 6 USGS streamgages on the Pit River, across California. 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 Pit River?
- Yes, at 2 of the 6 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 Pit 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.
