KERRVILLE, Texas (AP) — Just three people remain missing — down from nearly 100 at last count — since the Texas Hill Country was pounded by massive flooding on July 4, officials said.

Officials praised rescuers for the sharp reduction in the number of people on the missing list: Just days after the catastrophic flooding, more than 160 people were said to be unaccounted for in Kerr County alone.

“This remarkable progress reflects countless hours of coordinated search and rescue operations, careful investigative work, and an unwavering commitment to bringing clarity and hope to families during an unimaginably difficult time,” Kerrville City Manager Dalton Rice said in a statement.

The death toll in Kerr County, 107, held steady for much of this week even as the intensive search continued. The flash floods killed at least 135 people in Texas over the holiday weekend, with most deaths along the Guadalupe River in Kerr County, about 60 miles (100 kilometers) northwest of San Antonio.

Just before daybreak on July 4, the destructive, fast-moving waters rose 26 feet (8 meters) on the Guadalupe, washing away homes and vehicles.

The floods laid waste to the Hill Country, a popular tourist destination where campers seek out spots along the river amid the rolling landscape. It is naturally prone to flash flooding because its dry, dirt-packed soil cannot soak up heavy rain.

Vacation cabins, youth camps campgrounds fill the riverbanks and hills of Kerr County, including Camp Mystic, a century-old Christian summer camp for girls. Located in a low-lying area of a region known as “flash flood alley,” Camp Mystic lost at least 27 campers and counselors.
