TEXAS FLOW REPORT

Last Updated: January 1, 2026

Texas streamflow conditions currently show a mosaic of variations, with a striking anomaly at Lelia Lk Ck where the streamflow has surged exceptionally, posting a massive 24-hour change of 1,149,900 cfs, hitting 2,126.52% of the normal flow, which may indicate a significant flooding event or data error that should be scrutinized by local authorities. Conversely, the majority of other sites such as Red River near De Kalb, Little Cypress Creek near Jefferson, and various segments of the Sabine and Neches Rivers are reporting streamflows drastically below normal, ranging from 90% to 97% below average, suggesting widespread flow droughts that could impact water supply and local ecosystems. Water and river enthusiasts, particularly whitewater aficionados, should note that the current gage height at Elm Fork Trinity River near Lewisville has risen notably to 6.42 feet with an increase in flow of 180.52 cfs, which may appeal to thrill-seekers, but caution is advised due to potential instabilities in water levels.

Major rivers such as the Trinity River are showing lower-than-average flows across several locations, with the Trinity River at Dallas flowing at 414 cfs, which is 82.02% below normal. The Brazos River near Hempstead is also low, flowing at 557 cfs, 94.2% below the norm. Waterway conditions in urban areas, including Houston, reveal diverse streamflow changes, where Brays Bayou has increased slightly by 2.48 cfs, yet remains 58.02% below normal. However, in contrast, E Fork Trinity River below Lake Ray Hubbard is showing a significant positive flow change, registering 104 cfs, which is 141.52% of the normal streamflow, potentially impacting recreational activities and adjacent communities. As river conditions continue to fluctuate, residents and visitors should stay updated on local water conditions for safe recreational planning and to anticipate potential water resource management issues.

       



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.
