Total streamflow across the Bighorn River was last observed at 5,464 cfs, and is expected to yield approximately 10,838 acre-ft of water today; about 31% of normal. River levels are low and may signify a drought. Average streamflow for this time of year is 17,505 cfs, with recent peaks last observed on 2023-06-26 when daily discharge volume was observed at 66,500 cfs.

Maximum discharge along the river is currently at the Bighorn R At Worland Wyo reporting a streamflow rate of 4,350 cfs. However, the streamgauge with the highest stage along the river is the Bighorn River Near St. Xavier with a gauge stage of 59.39 ft. This river is monitored from 5 different streamgauging stations along the Bighorn River, the highest being situated at an altitude of 4,051 ft, the Bighorn R At Worland Wyo.

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

Bighorn River

The Bighorn River is a 461-mile long river that flows through Montana and Wyoming. The river has a rich history dating back to the early Native American tribes who used the river for food and transportation. In the early 1800s, fur trappers and explorers traveled up the river, followed by farmers and ranchers who settled in the region. Today, the Bighorn River is important for irrigation, agriculture, and recreation. The river is fed by several reservoirs, including the Yellowtail Dam, which was constructed in the 1960s to provide flood control and hydroelectric power. The Bighorn River is a popular destination for fly fishing, with rainbow and brown trout being the most sought-after species. The river is also popular for rafting and kayaking, with several companies offering guided tours.

FAQ

About the Bighorn River

Where does the data for the Bighorn 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.
