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

Colorado River

The Colorado River is a major river in the western United States, stretching approximately 1,450 miles from the Rocky Mountains of Colorado to the Gulf of California in Mexico. The river is known for its significant role in the history and settlement of the American West. The river supports a large agricultural and recreational industry, providing irrigation water to millions of acres of farmland and serving as a popular destination for rafting, kayaking, and fishing. The river's hydrology has been significantly altered by the construction of numerous dams and reservoirs, including the Hoover Dam and Lake Powell. These structures have helped to regulate water flow and provide hydroelectric power to the region, but have also caused ecological damage and contributed to the decline of several native fish species.

FAQ

About the Colorado River

Where does the data for the Colorado 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.
