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.

Mission River
The Mission River is a 120-mile-long river in South Texas that flows into the Gulf of Mexico. It has a rich history, having been used by indigenous peoples for thousands of years, and later, by Spanish explorers and settlers. The river is primarily fed by rainfall and is subject to periodic flooding. There are several reservoirs along the river, including Lake Corpus Christi, which was created by the construction of Wesley E. Seale Dam in the 1950s. The reservoir provides drinking water for the city of Corpus Christi and is also used for recreational activities such as fishing, boating, and camping. The Mission River and its tributaries are also used for agricultural purposes, particularly for growing cotton and citrus crops.
Recreation along the Mission River
Fishing access and paddle runs Snoflo tracks within the watershed.
Track the Mission River in the Snoflo app
Set per-gauge push alerts (e.g. "alert me when flow at the Russian R Nr Healdsburg crosses 5,000 cfs"), and Snoflo's iOS app pushes the moment USGS reports the crossing.
About the Mission River
Where does the data for the Mission 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.
