Gallatin River river
Total streamflow across the Gallatin River was last observed at 1,080 cfs, and is expected to yield approximately 2,142 acre-ft of water today; about 23% of normal. River levels are low and may signify a drought. Average streamflow for this time of year is 4,743 cfs, with recent peaks last observed on 2022-06-14 when daily discharge volume was observed at 16,110 cfs.
Maximum discharge along the river is currently at the Gallatin River Near Gallatin Gateway Mt reporting a streamflow rate of 1,050 cfs. However, the streamgauge with the highest stage along the river is the Gallatin River At Logan Mt with a gauge stage of 5.16 ft. This river is monitored from 2 different streamgauging stations along the Gallatin River, the highest being situated at an altitude of 5,189 ft, the Gallatin River Near Gallatin Gateway 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.

Gallatin River
The Gallatin River is a 120-mile-long tributary of the Missouri River located in the U.S. states of Wyoming and Montana. It was named after Albert Gallatin, a former U.S. Treasury Secretary. The river flows through rugged mountain terrain and is a popular destination for fly fishing, rafting, and kayaking. The river's hydrology is influenced by several reservoirs, including the Hebgen Lake Dam and the Ennis Dam, which regulate water flow and provide hydroelectric power. The Gallatin River has also played a significant role in the region's agricultural development, providing irrigation water for crops such as hay and grain. In recent years, concerns have been raised about the impact of recreational use on the river's ecosystem, prompting efforts to protect and conserve its natural resources.

About the Gallatin River
Where does the data for the Gallatin 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.
