More than 111 people have died across six counties after flash flooding from heavy rain began affecting the state last week.

Rain rushing to the Guadalupe took it from a depth of less than 8 feet to 37.5 feet, a deluge with as much volume as an aircraft carrier over five minutes.

Flash floods surged through in the middle of the night, but many local officials appeared unaware of the unfolding catastrophe, initially leaving people near the river on their own.

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.

Also: San Antonio mourned the victims in a Travis Park vigil; UTSA said one of its teachers died in the Guadalupe River flood; Kerrville officials said a privately owned drone collided with a helicopter conducting search and rescue operations.

New human settlements constructed in recent years have made the waterway more hazardous, UT-Arlington civil engineering professor says.

Before hundreds of first responders and volunteers from around the country came to help, it was the local residents of Texas Hill Country who faced down a deadly wall of water along the Gaudalope River and witnessed terrifying scenes.

Local businesses and vacationers are picking up the pieces after devastating flooding along the Guadalupe River in Kerrville.

The organizations working together to help the flood victims said that 'no additional in-kind donations (clothing, food, supplies) are needed in Kerrville.' They said the best way to help is with monetary donations.
