North Carolina Wildlife Enforcement Officer Patrick Brown said four dive teams were in the water today looking for John Sutton.
As of this report, there have been no results.
The searches today have centered around a perimeter of the Gaston Dam where Sutton, 31, had been fishing for bait that morning.
The dive teams each have different types of Sonar, Brown said. He said the area where responders believe Sutton may be is about 60-feet deep and rocky, which makes underwater imaging difficult.
A dive team was also going to concentrate on the length of the dam.
An intensive search effort Sunday brought out between 16 and 18 boats and searchers combed the islands along the Halifax and Northampton shorelines hoping Sutton may have made it to land.
Brown said circumstances described by witness accounts that morning have not changed and it is believed that Sutton, an experienced boater and fisherman, had been net casting in the area of the dam called the boil, where the water from power generation is the most turbulent.
Brown said Sutton is experienced in handling a boat in the boil, and had made at least three trips that evening.
On the fourth trip, Brown said the boat hit the pillar at full throttle and Sutton was most likely thrown from the boat.
