Two Texas women can thank a policeman for saving their lives yesterday after they drove into a lake.

Even more amazing that the story of how they got there, is the fact that the entire rescue was caught on the cops dash-cam.

According to KWTX, the women got lost driving in the darkened Robertson Park in Dallas and mistakenly drove down a boat launch, thinking it was a road that would lead them to a highway.

Rockwell County Sheriff's Deputy Kevin Rowan happened to be near the scene and heard the two yelling for help from the sinking cars back seat.

He made the decision to get into the water after it appeared they could not get out.  It was the right decision, after he broke the windows he pulled the two to safety.
