A flash flood in the Texas Hill Country on the Fourth of July killed dozen of people, including 27 people at an all-girls summer camp along the Guadalupe River.

For the past 66 years, the Hill Country Arts Foundation has provided Hill Country residents and visitors alike a place to see shows just feet away from the Guadalupe River.

The rivers etching the terrain are a beloved feature of the rapidly growing region. But last week’s flooding was an agonizing reminder of the dangers they pose.
