Missouri River Flow
As of 2026-07-29, the Missouri River is flowing at a combined 568,150 cfs across 25 USGS streamgauges — 58% of normal for this time of year, versus a seasonal average of 984,942 cfs.
Total streamflow across the Missouri River was last observed at 568,150 cfs, and is expected to yield approximately 1,126,912 acre-ft of water today; about 58% of normal. River levels are low and may signify a drought. Average streamflow for this time of year is 984,942 cfs, with recent peaks last observed on 2019-05-31 when daily discharge volume was observed at 3,557,200 cfs.
Maximum discharge along the river is currently at the Missouri River At Hermann reporting a streamflow rate of 53,300 cfs. However, the streamgauge with the highest stage along the river is the Missouri River At Decatur with a gauge stage of 20.02 ft. This river is monitored from 25 different streamgauging stations along the Missouri River, the highest being situated at an altitude of 3,911 ft, the Missouri River At Toston Mt.

Streamflow elevation profile
Each bubble is one gauge along the river, plotted by current streamflow (x-axis) vs elevation (y-axis), sized by gauge stage. Reading top-to-bottom traces the river from headwaters down to its mouth -- you can see flow accumulate as elevation drops.

Missouri River
The Missouri River is the longest river in North America, stretching over 2,341 miles from Montana to Missouri. It has been an integral part of American history, serving as a major transportation route for fur traders, pioneers, and explorers. The river's hydrology has been significantly altered by the construction of various reservoirs and dams, including the Garrison Dam, Oahe Dam, and Fort Peck Dam. These dams have helped with flood control, irrigation, and hydroelectric power generation. The Missouri River also holds significant recreational and agricultural value, with many communities relying on it for fishing, boating, and irrigation. The river and its tributaries provide habitat for a variety of fish species, including catfish, bass, and walleye. The Missouri River remains an important part of American history and continues to play a vital role in the lives of many communities today.

About the Missouri River
How is the Missouri River flowing right now?
As of 2026-07-29, the Missouri River is flowing at a combined 568,150 cfs across its USGS streamgauges, about 58% of normal for this date. The live per-gauge breakdown and 24-hour trend are shown above.
Is the Missouri River running high or low right now?
Check the percent-of-normal figure on this page: above 100% means the river is running higher than its seasonal average for the date, below 100% means lower. The per-gauge table shows which reaches are highest and lowest.
Where does the data for the Missouri River come from?
Streamflow and gauge stage data are sourced from the U.S. Geological Survey (USGS) National Water Information System. The aggregate flow shown at the top of the page is computed by Snoflo as the sum of all monitored gauges along the river.
How is "percent of normal" calculated?
Today's aggregate streamflow is compared to the historical average aggregate streamflow on this calendar day across the river's full record. 100% means right on average; values above 100% indicate above-normal flow (wet year); values below indicate below-normal (dry year or drought).
Why are some gauges showing very different flows?
Gauges along a river measure flow at different points: headwater gauges read what's coming off the snowpack or mountain runoff; downstream gauges integrate everything upstream, including tributary inputs. Wide spreads usually mean a tributary is contributing significantly between gauges.
What's the elevation profile chart showing?
Each bubble is one gauge along the river, plotted by streamflow (x-axis) and elevation (y-axis), sized by gauge stage. Reading top-down traces the river from headwaters to mouth -- you can see flow build as elevation drops.
Can I get alerts when a specific gauge crosses a threshold?
Yes -- alerts are managed in the Snoflo iOS app on a per-gauge basis. Open any individual streamgauge from the table above and favorite it to set a discharge threshold.
