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

South Platte River

The South Platte River is a tributary of the Platte River and flows through Colorado and Nebraska. It is 435 miles long and has a rich history of being used for transportation, irrigation, and recreation. The river originates in the Rocky Mountains and runs through several reservoirs and dams, including Eleven Mile Canyon Reservoir and Chatfield Reservoir. These reservoirs are used for irrigation, hydroelectric power, and flood control. The South Platte River also provides recreational opportunities such as fishing, kayaking, and camping. In addition to its recreational uses, the river is an important source of water for agriculture, including crops such as corn, wheat, and alfalfa. Despite its many uses, the South Platte River faces threats of pollution and overuse, highlighting the importance of responsible management and conservation efforts.

FAQ

About the South Platte River

Where does the data for the South Platte 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.
