Encampment River flows and levels

Encampment River is gauged at 2 USGS streamgages in Wyoming, each tracked by Rivermatics. The mainstem runs about 42 miles (68 km) from headwaters to outlet. It drains into the Mississippi River system. Drainage area at the gauges ranges from 73 square miles at Encampment River Ab Hog Park Creek, near Encampment, WY up to 262 at Encampment River at Mouth, near Encampment, WY. The gauged reach falls about 1,302 feet, from 8,267 feet down to 6,965. 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.

Common questions

When does the Encampment River run highest?
June, on the long-term record at Encampment River at Mouth, near Encampment, WY — the furthest-downstream gauge Rivermatics tracks on this river. Median daily flow there is about 1,056.2 cfs that month, against 48.5 cfs in September, 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 Encampment River?
Rivermatics tracks 2 USGS streamgages on the Encampment River, across Wyoming. 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 Encampment 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 Encampment River part of?
The Encampment River drains into the Mississippi 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 Encampment 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.
