Although Kerr County was hit hardest by flooding, at least seven others have been confirmed dead in different parts of Texas. About 150 miles east of Camp Mystic, Travis County has confirmed at least four deaths, county spokesperson Hector Nieto told CBS News by phone Saturday night. Travis County includes the Texas capital city of Austin.

Texas Gov. Greg Abbott visited the all-girls retreat Camp Mystic late Saturday as the death toll from Friday's flash flooding of the Guadalupe River continued to rise through the weekend.

Campers as young as 8-years-old were swept away by catastrophic flooding in central Texas when tropical rainfall sent the Guadalupe River surging onto Camp Mystic, where the young campers slept.
