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 Scotts C Ab State Route 29 A Upper Lake, CA
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 4 years of data), averaged within each month. These describe the historical normal range — they are not a forecast and not today's reading.
Only 7 of 12 months have enough record to summarize; the rest are omitted.

Common questions
- When does the Scotts C run highest?
- February, on the long-term record at Scotts C Ab State Route 29 A Upper Lake, CA — the furthest-downstream gauge Rivermatics tracks on this river. Median daily flow there is about 429.7 cfs that month, against -0.2 cfs in October, 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 Scotts C?
- Rivermatics tracks 2 USGS streamgages on the Scotts C, 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.
- What river system is the Scotts C part of?
- The Scotts C drains into the Sacramento 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 Scotts C 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.
