Marmaton River flows and levels

Marmaton River is gauged at 4 USGS streamgages in Kansas and Missouri, each tracked by Rivermatics. The mainstem runs about 98 miles (159 km) from headwaters to outlet. It drains into the Mississippi River system. Drainage area at the gauges ranges from 84 square miles at Marmaton River near Uniontown, KS up to 1,074 at Marmaton River near Nevada, MO. The gauged reach falls about 134 feet, from 871 feet down to 738. 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 Marmaton River near Nevada, MO

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 23 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 Marmaton River run highest?
May, on the long-term record at Marmaton River near Nevada, MO — the furthest-downstream gauge Rivermatics tracks on this river. Median daily flow there is about 939.7 cfs that month, against 29.5 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 Marmaton River?
Rivermatics tracks 4 USGS streamgages on the Marmaton River, across Kansas and Missouri. 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 Marmaton River?
Yes, at 4 of the 4 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 Marmaton River part of?
The Marmaton 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 Marmaton 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.
