Here's what to know about the deadly flooding, the colossal weather system that drove it and ongoing efforts to identify victims.

The camp, which was established in 1926, has experienced a long history of flooding from the Guadalupe River, leading to multiple evacuations and damages across the campgrounds, according to CNN. The July 4 flood was the most damaging disaster in the area, followed by a flooding in 1987 in which 10 children at a different camp nearby were killed.

The Texas summer camp where children died in flooding is in an area meteorologists refer to as "Flash Flood Alley."
