Catastrophic flooding occurred in the Texas Hill Country on July 4, 2025, when the Guadalupe River surged. The river rose about 30 feet in an hour, causing widespread damage and loss of life. At least 137 people were killed in the disaster.

The flooding affected families celebrating the holiday weekend, with water racing through neighborhoods and campgrounds. Homes, cabins, and vehicles were inundated, and roads became impassable.

Further details about the flooding and its aftermath are available from NBC 5, which documented the devastation and examined the questions it raised one year after the event.
