TEXAS FLOW REPORT

Last Updated: December 29, 2025

The state of Texas is experiencing a notable variation in river and stream conditions, with many water bodies reporting significantly lower than normal streamflow levels, indicative of flow droughts and potential water scarcity for various uses. The Sabine River near Carthage, a key river within the state, has shown a considerable decrease in streamflow with a current measurement of 9200 cubic feet per second (cfs), which is -11.82% of the normal flow, and a gage height of 12.51 feet. Such conditions could affect local ecosystems and water-dependent activities. On the other hand, the East Fork Trinity River below Lake Ray Hubbard near Forney has seen an impressive increase to 106 cfs, 144.18% of its average, with a gage height of 8.1 feet, potentially impacting whitewater trails and nearby communities such as Forney.

In the Houston area, Brays Bayou at MLK Jr Blvd has witnessed a dramatic rise in streamflow to 8710 cfs, a significant 44.52% increase from the norm, suggesting a risk of flooding, while the gage height stands at 1.25 feet. The Angelina River near Alto is down to 179 cfs, -82.63% from the typical flow, with a gage height of 12.06 feet, which may be of concern to river enthusiasts and local water resource management. Across the state, these variations in streamflow have the potential to influence recreational activities such as fishing and kayaking, and are critical for municipalities and agricultural stakeholders to monitor for resource planning and flood risk preparation.

       



Texas has a humid subtropical climate with hot summers and mild winters. Major surface flows include the Rio Grande, Colorado, and Brazos rivers, among others. The state has numerous reservoirs and dams, including the 200-mile-long Lake Texoma and the 170-mile-long Lake Travis. Hydrology in Texas is influenced by seasonal changes in precipitation, particularly in the spring and fall. Major tributaries include the Guadalupe, Nueces, and Trinity rivers. Watershed data is important for understanding the hydrology of Texas, with notable watersheds including the Red River, Sabine River, and San Antonio River. Snowpack data in the western mountains of Texas can also play a role in the state's hydrology, particularly during drought conditions.


       

Winter Storm Warnings

December 29 2025

Residents of Texas are advised to exercise caution as several weather advisories are in effect across the state. Yoakum and Terry Counties may experience light snow with potential minor accumulations on grassy surfaces, but roadways are expected to remain clear. Strong northerly winds with gusts up to 45 mph are anticipated in Deep South Texas, including portions of Brownsville, affecting unsecured objects and potentially causing power outages. Coastal regions, specifically Kenedy, Willacy, and Cameron Island Counties, face a high risk of rip currents, high surf with waves up to 8 feet, and minor coastal flooding, posing dangers to swimmers, surfers, and narrow beach areas. Additionally, wind advisories extend to south central and southeast Texas, including the Houston/Galveston area, where gusty winds may disrupt outdoor activities and decorations. Citizens should secure outdoor items, avoid hazardous coastal conditions, and stay updated on local advisories.
