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

Arkansas River

The Arkansas River is a major tributary of the Mississippi River, stretching for 1,469 miles across the central United States. The river has played a significant role in the history of the region, serving as a vital transportation route for Native Americans and early settlers. Today, the Arkansas River is a major source of irrigation for crops and a popular destination for recreational activities such as fishing and boating. The river is managed by a series of reservoirs and dams, including the John Martin Dam, the Kaw Dam, and the Keystone Dam. These structures help to regulate water flow and provide hydroelectric power. Despite its importance, the Arkansas River faces ongoing challenges, including pollution and water scarcity, which threaten the river's ecological health and the communities that depend on it.

FAQ

About the Arkansas River

Where does the data for the Arkansas 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.
