Total streamflow across the Maple River was last observed at 1,014 cfs, and is expected to yield approximately 2,011 acre-ft of water today; about 44% of normal. River levels are low and may signify a drought. Average streamflow for this time of year is 2,328 cfs, with recent peaks last observed on 2019-03-14 when daily discharge volume was observed at 18,300 cfs.

Maximum discharge along the river is currently at the Maple River At Mapleton reporting a streamflow rate of 436 cfs. However, the streamgauge with the highest stage along the river is the Maple River Bl Mapleton with a gauge stage of 9.77 ft. This river is monitored from 7 different streamgauging stations along the Maple River, the highest being situated at an altitude of 1,371 ft, the Maple R At Nd-Sd State Line.

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

Maple River

The Maple River is a 50-mile-long river in North Dakota that originates near Anamoose and flows into the Sheyenne River in Cass County. Its name comes from the abundance of sugar maple trees that used to grow along its banks. In the early 1900s, the Maple River was used for transportation and irrigation by local farmers. Today, the river is primarily used for recreation, including fishing, canoeing, and kayaking. The Maple River has several reservoirs throughout its length, including the Carpenter, Lake Juanita, and Baldhill reservoirs. The Carpenter Dam was built in 1928 and is used to regulate water levels and generate hydroelectric power. The Baldhill Dam was built in 1950 and is used for flood control. The Maple River is also used for irrigation, with several irrigation canals diverting water for agricultural use.

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 Maple River

Where does the data for the Maple 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.
