The driver of a vehicle swept away by floodwaters early Monday morning has been found dead.
According to a statement issued by the Bandera County Sheriff's Office, the woman called 911 at around 5:30 a.m. and reported that she was being carried downstream in the creek in the area of the Lower Mason Creek Road and could not get out of her vehicle because of fast-moving water.

The vehicle was located at about 4:30 p.m.
