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.

Trinity River
The Trinity River is a major river in Texas that flows 710 miles from its headwaters in the eastern side of the state, through the Dallas-Fort Worth metroplex, and into Trinity Bay on the Gulf of Mexico. The river was first explored by the Spanish in the 16th century and has played a significant role in the state's history, serving as a transportation route for early settlers and a source of water for agriculture and industry. The river supports several reservoirs and dams, including the Trinity River Authority's Lake Livingston Dam and the US Army Corps of Engineers' Lake Lewisville and Lake Ray Roberts. These reservoirs provide flood control, water storage, and recreational opportunities such as boating, fishing, and camping. The Trinity River is also used for irrigation and supports agricultural activities in the surrounding areas.

About the Trinity River
How is the Trinity River flowing right now?
As of 2026-09-12, the Trinity River is flowing at a combined 17,927 cfs across its USGS streamgauges, about 104% of normal for this date. The live per-gauge breakdown and 24-hour trend are shown above.
Is the Trinity River running high or low right now?
Check the percent-of-normal figure on this page: above 100% means the river is running higher than its seasonal average for the date, below 100% means lower. The per-gauge table shows which reaches are highest and lowest.
Where does the data for the Trinity 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.
