I can't say it enough. Although this was a bad one, it floods in the hill country, and people have died in the past. The only reason you are hearing about it now is because a lot of out-of-state people moved into the area that didn't know better.
The answer is easy, but it's one people don't want to hear. The best system is to not be on the rivers and streams when it's storming.

Camp Mystic was founded in 1926.
The youth camps have to be licensed and meet various standards in order to operate. There lots of rules and regulations in order to operate. I haven’t seen anything about building too close to river banks.
