KERRVILLE, Texas (AP) — Over the last decade, an array of Texas state and local agencies missed opportunities to fund a flood warning system intended to avert a disaster like the one that killed dozens of young campers and scores of others in Kerr County on the Fourth of July.

The Houston Texans were the first to announce their donations on Saturday, July 5, with more coming throughout the week. The Dallas Cowboys and the NFL Foundation joined the Texans on Sunday, July 6, with each contributing $500,000 in a $1.5 million total donation.

At least 19 of the cabins at Camp Mystic were located in designated flood zones, including some in an area deemed “extremely hazardous” by the county.

The data also highlights critical risks in other areas along the Guadalupe River in Kerr County, revealing more than twice as many Americans live in flood prone areas than FEMA's maps show.

The death toll from historic flooding in Texas' Hill Country rose to 104 Monday as Camp Mystic girls summer camp confirmed 27 campers and counselors died. Several other people remain missing.

Scott Ruskan, a Coast Guard swimmer, is credited with saving 165 people at the all-girls’ camp from deadly floods in Central Texas.

It’s just hard to wrap my head around” the devastation, Pamela Brown said during her live report from Camp Mystic in Kerr County.

Flash floods that hit central Texas devastated Hill Country during the Fourth of July holiday weekend, killing dozens of people.
