In 1987, sudden and intense rainfall caused the river to surge at an unprecedented rate in mid-July, leading to a tragedy that killed 10 campers at Pot O' Gold Christian Camp, a summer camp near Comfort, Texas. The campers drowned when their bus attempted to evacuate them and was overtaken by floodwater.

Generations of the same family have operated the summer camp since 1939. It counts family members of former president and governors as alumnae.

Authorities said at least 24 people have died in flooding around Kerr County, Texas, and officials are still performing water rescues.
