Total streamflow across the Teton River was last observed at 1,027 cfs, and is expected to yield approximately 2,037 acre-ft of water today; about 41% of normal. River levels are low and may signify a drought. Average streamflow for this time of year is 2,530 cfs, with recent peaks last observed on 2011-06-12 when daily discharge volume was observed at 12,480 cfs.

Maximum discharge along the river is currently at the Teton River Nr St Anthony Id reporting a streamflow rate of 683 cfs. However, the streamgauge with the highest stage along the river is the Teton River Bl South Fork Nr Choteau Mt with a gauge stage of 4.65 ft. This river is monitored from 5 different streamgauging stations along the Teton River, the highest being situated at an altitude of 5,963 ft, the Teton River Ab South Leigh Creek Nr Driggs Id.

Profile

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.

About this river

Teton River

The Teton River is a tributary of the Snake River located in eastern Idaho. It stretches about 81 miles, originating in the Teton Range of Wyoming and flowing westward into Idaho. The river is known for its scenic beauty and diverse recreational opportunities, including fishing, kayaking, and camping.

The Teton River has a complex hydrology system due to its location in the Snake River watershed. There are several dams and reservoirs along the river, including the Teton Dam and the Palisades Reservoir, which provide irrigation water for agriculture and hydroelectric power.

The Teton Dam, which was completed in 1976, was a significant engineering feat but tragically failed within a year of construction, causing a devastating flood that killed 11 people and destroyed numerous homes and farms.

Today, the Teton River is a popular destination for outdoor enthusiasts and supports a variety of agricultural practices, including potato and wheat farming. Despite its past challenges, the Teton River continues to provide valuable resources and recreational opportunities for the surrounding communities.

FAQ

About the Teton River

Where does the data for the Teton 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.
