7 USGS Streamgages
Walker River flows and levels
Walker River is gauged at 7 USGS streamgages in Nevada, each tracked by Rivermatics. The mainstem runs about 74 miles (119 km) from headwaters to outlet. It drains roughly 801 square miles at its outlet. The gauged reach falls about 360 feet, from 4,300 feet down to 3,940. Rivermatics issues a daily machine-learned 14-day flow outlook at 6 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 Walker River run highest?
- August, on the long-term record at Walker River below Mason Vly Wma at Rr Xing near Wabuska — the furthest-downstream gauge Rivermatics tracks on this river. Median daily flow there is about 192 cfs that month, against 36.6 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 Walker River?
- Rivermatics tracks 7 USGS streamgages on the Walker River, across Nevada. 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 Walker River?
- Yes, at 6 of the 7 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 Walker 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.
