Authorities said the victims were all family members and were riding on the pontoon boat. The driver, the father, was not injured. The family dog, also on the boat, is missing.

No one on the pontoon boat was wearing life jackets, officials said. They said the speed boat was driving well over 25 mph in a shallow part of the lake. No one on the speed boat was injured.

Rescue crews and about 50 volunteers were on the scene. Authorities said there is no indication of alcohol being a factor, but speed may have played a role in the accident.
