2 USGS Streamgages · Colorado River system

Piney River flows and levels

Piney River is gauged at 2 USGS streamgages in Colorado, each tracked by Rivermatics. The mainstem runs about 27 miles (44 km) from headwaters to outlet. It drains into the Colorado River system. Drainage area at the gauges ranges from 13 square miles at Piney River below Piney Lake, near Minturn, CO up to 85 at Piney River near State Bridge, CO. The gauged reach falls about 1,873 feet, from 9,160 feet down to 7,287. 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 Piney River near State Bridge, CO

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 82 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 Piney River run highest?
June, on the long-term record at Piney River near State Bridge, CO — the furthest-downstream gauge Rivermatics tracks on this river. Median daily flow there is about 315 cfs that month, against 12.7 cfs in February, 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 Piney River?
Rivermatics tracks 2 USGS streamgages on the Piney River, across Colorado. 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 Piney River?
Yes, at 2 of the 2 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 Piney River part of?
The Piney River 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 Piney 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.
