Texas streamflow conditions present a diverse tapestry across the state, with significant variances indicating both potential flood and drought conditions in some areas. Notably, an extreme increase in streamflow was recorded at Lelia Lk Ck Bl Bell Ck near Hedley, showing an astonishing change of 1,149,900 cubic feet per second (cfs) over the last 24 hours, soaring to 2126.52% of the normal flow, which may signal imminent flooding risks. Contrariwise, the majority of rivers, such as the Sabine River near Gladewater and the Neches River near Neches, consistently exhibit streamflows significantly below normal, with reductions around 90-97%, suggesting a widespread low water trend. These data points are critical for communities along these waterways and for river and outdoor enthusiasts who frequent popular whitewater trails, such as those on the Brazos River.
In particular, the Brazos River near Hempstead and the Trinity River, a key watershed for the Dallas-Fort Worth area, have shown dwindling flows, around 94% and up to 91% below normal respectively, possibly implicating flow droughts that could impact municipal water supplies and local ecosystems. Conversely, the E Fk Trinity River near Forney has experienced a major surge, with streamflow up to 613.42% of normal, indicating a massive influx of water that could affect nearby communities and recreational interests. Water enthusiasts and residents near these rivers should be aware of the current conditions, as such variations could impact water-based activities and necessitate awareness of flood advisories or water restrictions in the affected areas.
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.
