The search for 69-year-old William Neskorik ended Wednesday morning on Lake Ray Hubbard.
Dallas police confirm his body was found midday Wednesday by search and rescue teams.
According Dallas police, a 911 call was made on Tuesday afternoon concerning a pontoon boat drifting along the shoreline unanchored and unoccupied. That same person told officers they had seen the boat earlier in the day further out on the water.
The boat was discovered drifting a mile north of the Interstate 30 bridge, according to Dallas police.
When members of Texas Parks and Wildlife ran the registration on the boat they were able to determine it belonged to Neskorik. A short time later his truck was discovered at Bayview Marina.
Neskorik's family told the game warden he had gone out early Tuesday morning to fish.
Search crews started looking for the missing boater on Tuesday evening around 5 p.m. and continued searching until midnight.
They resumed their search on Wednesday morning and according to Dallas police, the game wardens are searching an area northwest of Becky Lane and Lakeshore in Rockwall.
According to Dallas police, an autopsy is being performed to determine cause of death.
