Total streamflow across the Roseau River was last observed at 881 cfs, and is expected to yield approximately 1,747 acre-ft of water today; about 38% of normal. River levels are low and may signify a drought. Average streamflow for this time of year is 2,298 cfs, with recent peaks last observed on 2019-10-15 when daily discharge volume was observed at 10,320 cfs.

Maximum discharge along the river is currently at the Roseau River Below State Ditch 51 Nr Caribou reporting a streamflow rate of 534 cfs. However, the streamgauge with the highest stage along the river is the Roseau River At Ross with a gauge stage of 5.99 ft. This river is monitored from 3 different streamgauging stations along the Roseau River, the highest being situated at an altitude of 1,050 ft, the Roseau River Below South Fork Near Malung.

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

Roseau River

The Roseau River, located in Minnesota and Manitoba, Canada, is about 248 kilometers long. Historically, the river was used by the Dakota, Ojibwe, and Metis people for transportation and fishing. Today, it is used for recreational activities such as fishing, canoeing, and boating. The river's hydrology is primarily influenced by precipitation and snowmelt. The river is also impacted by three reservoirs: Roseau Lake, Malung Lake, and Pinecreek Lake, which are controlled by dams. These reservoirs are used for flood control, irrigation, and to supply drinking water. Additionally, the Roseau River is an important source of water for agricultural purposes, including irrigation for crops like sugar beets, potatoes, and soybeans. The river is an important natural resource for the region, providing recreational and economic benefits.

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 Roseau River

Where does the data for the Roseau 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.
