https://www.weather.gov/ewx/wxevent-19870717Okay so I've been digging into this and this is not a hundred year flood zone, this River has flooded multiple times within 100 years.
If people want to live there along the river, fine. But to build camps and have hundreds of kids should be illegal. I for one will not send my kids to any camps along that river. Totally preventable, and due to social media and the news today more awareness of this year’s flood. It's happened before and it will happen again.
The Guadalupe River has a long and tragic history of flash flooding, especially in the Texas Hill Country — often called “Flash Flood Alley” for good reason. Here are some of the most significant events:
Major Guadalupe River Floods

Why This Region Floods So Often
- Steep terrain: Water rushes downhill rapidly.
- Rocky, shallow soil: Poor absorption leads to fast runoff.
- Converging rivers: Guadalupe’s forks meet near Hunt and Comfort.
- Tropical moisture: Gulf and Pacific systems often stall here.
- Population growth: More people and camps near floodplains increase risk.
The Guadalupe River doesn’t just flood — it transforms into a raging torrent with little warning.
