Gavin Walston, a Center Point resident, captured the quickly rising floodwaters from the Guadalupe River in Texas on Friday. The fast-moving water carried large pieces of debris, wiped out tall trees and a house.

Families sifted through waterlogged debris Sunday and stepped inside empty cabins at Camp Mystic, an all-girls summer camp ripped apart by flash floods that washed homes off their foundations and killed at least 82 people in central Texas.
