The water comes into the river faster than it can flow out so the water stacks on itself

eight meters … in just 45 minutes.
How does it work? What area was covered with water? Or the river and camp were in some kind of, I don’t know, cleft of something? I can’t easily imagine a river’s water to become higher by 8 m in an hour.

It’s hard to imagine how much rain occurs in the thunderstorms that hit this area, and frankly, most of tornado ally. It’s heavy on an average storm, but the real flash floods like this are insane. The ground is incapable of absorbing the rain levels, and floods happen in minutes.

The area that camp mystic is on is literally called “flash flood alley” because of the possibility of this happening. The area has thin soil that doesn’t really soak up much water and bedrock that keeps it on the surface. Combine that with a bunch of creeks that all converge to a river in the area and you get what happened this weekend.
