3 USGS Streamgages · Colorado River system
Meadow Valley Wash flows and levels
Meadow Valley Wash is gauged at 3 USGS streamgages in Nevada, each tracked by Rivermatics. The mainstem runs about 153 miles (246 km) from headwaters to outlet. It drains into the Colorado River system. It drains roughly 2,395 square miles at its outlet. The gauged reach falls about 3,799 feet, from 5,654 feet down to 1,855. 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 Meadow Valley Wash run highest?
- March, on the long-term record at Meadow Valley Wash near Rox, NV — the furthest-downstream gauge Rivermatics tracks on this river. Median daily flow there is about 2.2 cfs that month, against 0.7 cfs in July, 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 Meadow Valley Wash?
- Rivermatics tracks 3 USGS streamgages on the Meadow Valley Wash, 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 Meadow Valley Wash?
- Yes, at 2 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 Meadow Valley Wash part of?
- The Meadow Valley Wash drains into the Colorado 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 Meadow Valley Wash 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.
