Two of the four children, a 5yr old and 6 yr old, were found alive on an embankment. Both were transported to Children's Medical Center in stable condition.
The other two children, a 9yr old and 7yr old, were ejected from the car into the water. The 9yr old was pulled out of the water by Dallas Fire fighters and was transported to Children's Medical Center in stable condition.
Rescuers recovered the body of the 7yr old girl in the water at 8:10pm, two hours after the accident.
Dallas County Sheriff investigators are trying to determine what caused the accident.
