Salmon River river
Total streamflow across the Salmon River was last observed at 9,310 cfs, and is expected to yield approximately 18,466 acre-ft of water today; about 17% of normal. River levels are low and may signify a drought. Average streamflow for this time of year is 56,282 cfs, with recent peaks last observed on 2017-06-02 when daily discharge volume was observed at 129,510 cfs.
Maximum discharge along the river is currently at the Salmon River At White Bird Id reporting a streamflow rate of 23,300 cfs. This is also the highest stage along the Salmon River, with a gauge stage of 19.56 ft at this location. This river is monitored from 9 different streamgauging stations along the Salmon River, the highest being situated at an altitude of 5,911 ft, the Salmon River Bl Yankee Fork Nr Clayton Id.

Maximum streamflow discharge by year
The single highest aggregate discharge recorded each year. Spotting the multi-year trend reveals droughts vs. wet cycles long before the headline daily flow does.

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.

Salmon River
The Salmon River is a 425-mile-long river in western Idaho that is known for its world-class rapids and salmon fishing. The river's history dates back to the Native American tribes that used the river for fishing and transportation. The river's hydrology is influenced by its headwaters in the Sawtooth Mountains, which provide a consistent flow of cold, clear water. The river is home to several reservoirs and dams, including the Lower Salmon Falls Dam and the Little Salmon River Dam, which provide hydroelectric power and irrigation for agricultural purposes. The Salmon River is also popular for recreational activities, including rafting, fishing, and camping. The river's diverse landscape and rich history make it a unique destination for outdoor enthusiasts and history buffs alike.

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