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.

Dearborn River
The Dearborn River is a tributary of the Missouri River in Montana, USA. It spans a length of 70 miles and has a drainage area of 1,100 square miles. The river flows through the Lewis and Clark National Forest and has a rich history dating back to the Lewis and Clark Expedition. The river is also well-known for its recreational activities such as fishing, camping, and kayaking. The Holter Dam and the Hauser Dam are two major hydroelectric facilities on the Missouri River that have a direct impact on the Dearborn River. These dams regulate the flow of water and provide hydroelectric power to the surrounding areas. The river is also used for agricultural purposes such as irrigation, which supports the production of a variety of crops, including hay, grain, and vegetables.

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