Comal River river
Total streamflow across the Comal River was last observed at 255 cfs, and is expected to yield approximately 506 acre-ft of water today; about 124% of normal. River levels are high. Average streamflow for this time of year is 207 cfs, with recent peaks last observed on 2025-07-07 when daily discharge volume was observed at 1,608 cfs.
Maximum discharge along the river is currently at the Comal Rv At New Braunfels reporting a streamflow rate of 159 cfs. This is also the highest stage along the Comal River, with a gauge stage of 3.72 ft at this location. This river is monitored from 3 different streamgauging stations along the Comal River, the highest being situated at an altitude of 625 ft, the Comal Rv (Nc) Nr Landa Lk.

Maximum streamflow discharge by year
The single highest aggregate discharge recorded each year. Spotting the multi-year trend reveals droughts vs. wet cycles long before the headline daily flow does.

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.

Comal River
The Comal River is a scenic 2.5-mile-long river located in central Texas. It is a popular destination for tubing, swimming, and kayaking, and is known for its crystal-clear water and picturesque surroundings. Historically, the river was used by Native Americans for fishing and hunting, and later by German settlers for agriculture and transportation. The river is fed by natural springs and is protected by various environmental conservation programs. There are two dams on the Comal River, including the Comal Springs Dam and the Lake Dunlap Dam. These dams were constructed for flood control and to create reservoirs for water storage. The river is also used for irrigation purposes for nearby farmland.

About the Comal River
Where does the data for the Comal 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.
