Heart River river
Total streamflow across the Heart River was last observed at 161 cfs, and is expected to yield approximately 320 acre-ft of water today; about 11% of normal. River levels are low and may signify a drought. Average streamflow for this time of year is 1,445 cfs, with recent peaks last observed on 2014-04-09 when daily discharge volume was observed at 28,030 cfs.
Maximum discharge along the river is currently at the Heart River Nr Mandan reporting a streamflow rate of 68.8 cfs. This is also the highest stage along the Heart River, with a gauge stage of 9.36 ft at this location. This river is monitored from 5 different streamgauging stations along the Heart River, the highest being situated at an altitude of 2,452 ft, the Heart River Nr South Heart.

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.

Heart River
The Heart River is a 180-mile long tributary of the Missouri River located in North Dakota. It was named by early French explorers who saw the river as having the shape of a heart. The river is known for its scenic beauty, fishing opportunities, and recreational activities. The hydrology of the river is heavily influenced by the Garrison Dam, which was built in the 1950s and created Lake Sakakawea, one of the largest man-made reservoirs in the United States. The Heart River also flows through the city of Dickinson, where it is used for irrigation and agriculture. The river has a long history, with evidence of human habitation along its banks dating back thousands of years. Today, the Heart River remains an important resource for the people of North Dakota, providing water for irrigation, recreational opportunities, and scenic beauty.

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