Total streamflow across the Souris River was last observed at 537 cfs, and is expected to yield approximately 1,065 acre-ft of water today; about 15% of normal. River levels are low and may signify a drought. Average streamflow for this time of year is 3,580 cfs, with recent peaks last observed on 2011-06-29 when daily discharge volume was observed at 125,600 cfs.

Maximum discharge along the river is currently at the Souris River Nr Bantry reporting a streamflow rate of 296 cfs. However, the streamgauge with the highest stage along the river is the Souris River Nr Westhope with a gauge stage of 6.92 ft. This river is monitored from 6 different streamgauging stations along the Souris River, the highest being situated at an altitude of 1,615 ft, the Souris River Nr Sherwood.

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

Souris River

The Souris River is a 700-mile-long river that flows through Saskatchewan, North Dakota, and Manitoba. The river is named after the French word for mouse because of its winding path. The river has a long history of being used for transportation, fishing, and farming, but it also causes occasional flooding. The Souris River Basin is home to several reservoirs, including Lake Darling and Lake Darling Dam in North Dakota, which were constructed to manage water levels and prevent flooding. These reservoirs provide recreational opportunities, such as fishing and boating, and also support agricultural irrigation. The Souris River is an important water source for the region and is managed by various government agencies to balance the needs of agriculture, recreation, and flood control.

Track the Souris River in the Snoflo app

Set per-gauge push alerts (e.g. "alert me when flow at the Russian R Nr Healdsburg crosses 5,000 cfs"), and Snoflo's iOS app pushes the moment USGS reports the crossing.

FAQ

About the Souris River

Where does the data for the Souris 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.
