Camp Mystic, a private Christian summer camp for girls, had to be evacuated overnight after “catastrophic” flooding along the Guadalupe River.

Lt. Gov. Dan Patrick said Friday during a press conference that about 23 girls were still missing after major flooding at a private Christian summer camp in Hunt.

Flooding in central Texas caused the Guadalupe River to flood. A Christian girls camp, Camp Mystic, was affected and some campers are missing.
