Boise River river
Total streamflow across the Boise River was last observed at 2,650 cfs, and is expected to yield approximately 5,256 acre-ft of water today; about 36% of normal. River levels are low and may signify a drought. Average streamflow for this time of year is 7,401 cfs, with recent peaks last observed on 2017-06-05 when daily discharge volume was observed at 27,530 cfs.
Maximum discharge along the river is currently at the Boise River Nr Twin Springs Id reporting a streamflow rate of 2,330 cfs. However, the streamgauge with the highest stage along the river is the Boise River Nr Parma Id with a gauge stage of 9.81 ft. This river is monitored from 5 different streamgauging stations along the Boise River, the highest being situated at an altitude of 3,257 ft, the Boise River Nr Twin Springs Id.

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.

Boise River
The Boise River is a 102-mile-long river in Idaho that flows through Boise and empties into the Snake River. The river played a crucial role in the development of the area, as it was used for irrigation and transportation. The river is fed by many tributaries, including the Payette River, and has several major reservoirs, including Lucky Peak, Arrowrock, and Anderson Ranch. These reservoirs were built to store water for irrigation and flood control. The river is also used for recreational activities such as fishing, boating, and rafting. The river provides water for agriculture, helping to sustain crops in the region. Despite challenges related to pollution and development, efforts have been made to preserve and protect the river's natural resources.

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