Maple River Flow
As of 2026-08-31, the Maple River is flowing at a combined 122 cfs across 7 USGS streamgauges — 17% of normal for this time of year, versus a seasonal average of 705 cfs.
Total streamflow across the Maple River was last observed at 122 cfs, and is expected to yield approximately 242 acre-ft of water today; about 17% of normal. River levels are low and may signify a drought. Average streamflow for this time of year is 705 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 86.3 cfs. However, the streamgauge with the highest stage along the river is the Maple River Nr Mapleton with a gauge stage of 8.24 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.

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.

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.

About the Maple River
How is the Maple River flowing right now?
As of 2026-08-31, the Maple River is flowing at a combined 122 cfs across its USGS streamgauges, about 17% of normal for this date. The live per-gauge breakdown and 24-hour trend are shown above.
Is the Maple River running high or low right now?
Check the percent-of-normal figure on this page: above 100% means the river is running higher than its seasonal average for the date, below 100% means lower. The per-gauge table shows which reaches are highest and lowest.
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.
