More harrowing stories of survival are being told in the wake of historic flash flooding in central Texas that claimed at least 120 lives, including dozens of children who were at Camp Mystic, a historic summer camp nestled along the Guadalupe River.

Plans to develop a flood monitoring system in the Texas county hit hardest by deadly floods were scheduled to begin only a few weeks later.

Officials in Kerr County, where the majority of the deaths from the July 4 flash floods occurred, have yet to detail what actions they took in the early hours of the disaster.

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.

With more than 170 still missing, communities must reconcile how to pick up the pieces around a waterway that remains both a wellspring and a looming menace.
