LEWISVILLE Two dive teams returned to Lewisville Lake Sunday morning to search for a man who is presumed to have drowned.
The 50-year old man disappeared on Saturday as he was being towed on an inner tube behind a personal watercraft.
Rescue workers were using sonar equipment to try to find his body under the surface of the water near the Lake Park party cove. The victim's identity was not released.
At least seven people have drowned this year at Lewisville Lake.
