DALLAS—It was a deadly Fourth of July weekend on Texas lakes as authorities reported at least eight drownings, including a 3-year-old girl whose body was found floating in Lewisville Lake in North Texas.

Four people died at Lewisville Lake : three men whose bodies were recovered Sunday and the 3-year-old Carrollton girl, Natalie Escobar, whose body was found Friday.

Juanita Lagunas identified two of the men as her boyfriend, Ismael Rangel, 31, of Houston, and his nephew, 18-year-old Saul Rangel of Lewisville. She said that after she and the men wanted to see who could swim farthest, they realized the water was too deep and began to return to land.

“We wanted to go back, and then Saul started yelling for help because he couldn’t breathe,” she said in Spanish. “Ismael went to help him, and I wanted to as well. But Ismael told me to go back to shore because he felt something in the water pulling him down.”

Eugenio Reyes, 26, of Dallas, had been swimming with friends Saturday when they noticed that he was missing. His body was pulled from the lake Sunday.

On Sunday night, 27-year-old Jose Andrade of Irving reportedly jumped into Grapevine Lake from a party boat and did not resurface, police said. Police said that Grapevine Fire Department divers located his body about half an hour later.

At Lake Ray Roberts, searchers found the body of a 31-year-old man who had gone scuba diving with his twin brother, said Capt. Neal Bieler of Texas Parks and Wildlife. The Tarrant County medical examiner’s office identified the man as Kenneth Harper, of Pilot Point.

On Friday, 13-year-old Shannon Allcock drowned at Joe Pool Lake in Grand Prairie, police said.

In the Austin area, a man drowned Saturday night after diving into the water to try to untwist a boat anchor, authorities said.
