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.

Clark Fork River
The Clark Fork River runs 310 miles through Montana, originating in the Rocky Mountains and ending at Lake Pend Oreille in Idaho. The river is an important water source for agricultural irrigation and hydroelectric power. It also has a rich history, as it was a primary mode of transportation for early settlers and served as a major trade route for Native American tribes. Several large dams and reservoirs are located along the river, including the Thompson Falls Dam and the Noxon Rapids Dam, which provide hydroelectric power and flood control. Recreational activities such as fishing, boating, and camping are popular along the river, and it is home to a diverse range of fish species, including rainbow trout and bull trout. However, the river has also faced environmental challenges due to mining and industrial pollution in the past.

Track the Clark Fork River in the Snoflo app
Set per-gauge push alerts (e.g. "alert me when flow at the Russian R Nr Healdsburg crosses 5,000 cfs"), and Snoflo's iOS app pushes the moment USGS reports the crossing.
About the Clark Fork River
Where does the data for the Clark Fork 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.
