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

Guadalupe River

The Guadalupe River is a 230-mile-long river that flows from the Texas Hill Country to the Gulf of Mexico. The river was named by Spanish explorers who discovered the area on the feast day of Our Lady of Guadalupe. The hydrology of the river is influenced by both natural factors, such as rainfall and evaporation, and human factors, such as water usage and dam management. The river has several reservoirs and dams, including Canyon Lake, Lake McQueeney, and Lake Placid. These structures are used for flood control, water supply, and hydroelectric power generation. The Guadalupe River is a popular recreational destination for fishing, swimming, and tubing, and also supports agricultural uses such as irrigation for crops like rice and sugarcane. The river is an important ecological resource, providing habitat for a diverse range of plant and animal species.

FAQ

About the Guadalupe River

Where does the data for the Guadalupe 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.
