Two days before flash floods on the Guadalupe River in Texas killed dozens of campers at a Christian girls summer camp, a state inspector approved operations, noting there was a written plan for responding to natural disasters.

The Department of State Health Services released records Tuesday showing the camp complied with a host of state regulations regarding “procedures to be implemented in case of a disaster.”

Camp Mystic was overrun by flash flooding that started on Independence Day. Rapidly rising waters ripped through the century-old all-girls Christian summer camp, killing at least 27 people. Others are still missing.

Here’s what to know about the deadly flooding, the colossal weather system that drove it in and around Kerr County, Texas, and ongoing efforts to identify victims.
