The crash happened shortly after 9 p.m. Saturday near Two Rivers State Recreation Area west of Omaha.
State Patrol Lt. Matt Sutter says 61-year-old Joni Carveth of Fresno, California, backed the vehicle out of a driveway and into the pond.
Carveth’s father, Dewey Andersen, had trouble getting out of the GMC Yukon. Carveth ran to a nearby home to call for help.
Rescuers found Andersen floating in the water and unresponsive. He died later at a hospital.
