Total streamflow across the Niobrara River was last observed at 3,441 cfs, and is expected to yield approximately 6,825 acre-ft of water today; about 52% of normal. River levels are low and may signify a drought. Average streamflow for this time of year is 6,614 cfs, with recent peaks last observed on 2020-12-28 when daily discharge volume was observed at 24,630 cfs.

Maximum discharge along the river is currently at the Niobrara River Nr. Verdel reporting a streamflow rate of 1,500 cfs. This is also the highest stage along the Niobrara River, with a gauge stage of 3.63 ft at this location. This river is monitored from 3 different streamgauging stations along the Niobrara River, the highest being situated at an altitude of 2,295 ft, the Niobrara River Near Sparks.

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

Niobrara River

The Niobrara River is a 570-mile-long river that runs through the central United States, starting in Wyoming and ending in Nebraska. The river has a rich history and was once used by Native American tribes for transportation and as a source of food. Today, the river is primarily used for recreation, including canoeing, kayaking, and fishing, and is home to several state parks and wildlife refuges.

The Niobrara River is fed by several tributaries and has several reservoirs and dams, including the Merritt Reservoir and the Spencer Dam. These reservoirs provide water for irrigation and hydroelectric power.

The river is also important to agriculture, with many farmers using its water for irrigation. However, the use of the river's water for agriculture has led to conflicts with recreational users and concerns about water quality. Despite these challenges, the Niobrara River remains a vital resource for the communities and ecosystems that rely on it.

FAQ

About the Niobrara River

Where does the data for the Niobrara 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.
