5 USGS Streamgages · Umpqua River system
N.Umpqua River flows and levels
N.Umpqua River is gauged at 5 USGS streamgages in Oregon, each tracked by Rivermatics. It feeds the North Umpqua River. It drains into the Umpqua River system. Drainage area at the gauges ranges from 170 square miles at N.Umpqua River above White Mule Creek, near Toketee Falls, OR up to 475 at N Umpqua River above Copeland Creek near Toketee Falls, OR. 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.

Typical flow by month at N Umpqua River above Copeland Creek near Toketee Falls, OR
The furthest-downstream gauge on this river, so the fullest flow it carries here. Long-term daily discharge percentiles from the USGS record (up to 77 years of data), averaged within each month. These describe the historical normal range — they are not a forecast and not today's reading.

Common questions
- When does the N.Umpqua River run highest?
- May, on the long-term record at N Umpqua River above Copeland Creek near Toketee Falls, OR — the furthest-downstream gauge Rivermatics tracks on this river. Median daily flow there is about 1,914.8 cfs that month, against 830 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 N.Umpqua River?
- Rivermatics tracks 5 USGS streamgages on the N.Umpqua River, across Oregon. 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 N.Umpqua River?
- Yes, at 5 of the 5 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 N.Umpqua River part of?
- The N.Umpqua River drains into the Umpqua 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 N.Umpqua 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.
