Extreme flooding has left at least 78 dead in Texas. 10 children and one counselor remain missing from Camp Mystic, a Christian girls camp.

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.

Rescuers maneuvering through challenging terrain, high waters and snakes including water moccasins continued their desperate search for the missing, including 10 girls and a counselor from the camp.
