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.

Rescuers searched for survivors at Camp Mystic on the bank of the Guadalupe River in Hunt, Texas, after deadly floods swept through the area on July 4.

Time-lapse footage filmed July 4 shows floodwaters from the Llano River rise over a causeway in Kingsland, Texas, submerging it completely in less than an hour.

Heavy rain poured over parts of central Texas, dumping more than a month's worth of rain for places like San Angelo.
