3 USGS Streamgages · New York Slough system

Cherry C flows and levels

Cherry C is gauged at 3 USGS streamgages in California, each tracked by Rivermatics. It feeds the Granite Creek. It drains into the New York Slough system. Drainage area at the gauges ranges from 118 square miles at Cherry C below Valley Dam near Hetch Hetchy, CA up to 234 at Cherry C below Dion River Holm Ph near Mather, CA. The gauged reach falls about 2,207 feet, from 4,343 feet down to 2,136. 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 Cherry C below Dion River Holm Ph near Mather, 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 63 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 Cherry C run highest?
May, on the long-term record at Cherry C below Dion River Holm Ph near Mather, CA — the furthest-downstream gauge Rivermatics tracks on this river. Median daily flow there is about 1,059.6 cfs that month, against 271.2 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 Cherry C?
Rivermatics tracks 3 USGS streamgages on the Cherry 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.
Is there a flow forecast for the Cherry C?
Yes, at 3 of the 3 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 Cherry C part of?
The Cherry C drains into the New York Slough 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 Cherry 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.
