GRAND PRAIRIE - A day after 57-year-old Walter Harrison went under the water, his body was recovered from Joe Pool Lake.
Grand Prairie Police and Fire Department Search and Rescue responded to a 911 call about the drowning shortly before 4 p.m. Sunday.
Monday, search crews brought in sonar technology, which helped locate Harrison's body, which was retrieved by divers.
Family reported that Harrison, of Arlington, jumped from a pontoon boat into the water to cool off and became fatigued. The 57-year-old man wasn't wearing a life jacket and struggled in the water. His family said he cried out for help, but they were unable to get to him before he went under.
Using sonar to search for any sign of the man, search crews with divers combed an area close to the lake's dam.
"They're doing sonar grid patterns, searching for hits to dive on," said Asst. Chief Murphy, with the Grand Prairie Fire Department, before the body was found and recovered early Monday afternoon.
It was supposed to be a fun day on the lake for the man and five other family members. They rented a pontoon boat from the local marina.
It's a tragedy on one of the busiest weekends of the year at the lake, where authorities say drownings happen far too often.
Grand Prairie police say it was the second drowning at the lake this year.
"People think they can jump in and cool off, but this happens every year," Murphy said. "If you're going to jump in the water, have a life jacket on."
Capt. Tony Norton with the Dallas County Game Warden said alcohol was not involved. They plan on using cell phone/GPS data from the family members onboard the boat to help triangulate an area where to conentrate their search.
