Cheyenne River river
Total streamflow across the Cheyenne River was last observed at 386 cfs, and is expected to yield approximately 766 acre-ft of water today; about 4% of normal. River levels are low and may signify a drought. Average streamflow for this time of year is 9,083 cfs, with recent peaks last observed on 2019-05-23 when daily discharge volume was observed at 89,511 cfs.
Maximum discharge along the river is currently at the Cheyenne R Near Plainview Sd reporting a streamflow rate of 238 cfs. However, the streamgauge with the highest stage along the river is the Cheyenne River At Redshirt with a gauge stage of 9.32 ft. This river is monitored from 7 different streamgauging stations along the Cheyenne River, the highest being situated at an altitude of 3,582 ft, the Cheyenne River Near Spencer.

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.

Cheyenne River
The Cheyenne River is a tributary of the Missouri River, with a length of 295 miles. It has played an important role in the history of the Cheyenne people, who used it for transportation and hunting. The river originates in the Black Hills of South Dakota and flows through the Cheyenne River Indian Reservation before joining the Missouri River. There are several dams and reservoirs along the river, including the Angostura Dam and Reservoir, which is used for irrigation and recreation, and the Belle Fourche Dam, which provides flood control and hydroelectric power. The river is also used for agriculture, particularly for grazing livestock. The Cheyenne River is an important source of water for the surrounding communities and plays a significant role in the ecological and economic well-being of the region.

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