Texas game wardens say the Independence Day weekend was among the deadliest in recent memory on North Texas lakes.
Seven people were reported drowned while swimming, boating and enjoying other activities on the water.
"We've had an extreme large number of drownings for one weekend this year," said Texas Parks and Wildlife Department Capt.David Modgling.
On Monday evening, divers from East Texas found the body of a 23-year-old man who went under at Lake Carolyn in Las Colinas on Wednesday while paddle boating.
"It is a tragic situation," said Irving Fire Assistant Operations Chief Tony Harvey. "It is sad for the family and all those out there that day that witnessed it."
Police said the man was in the water with his elbows on his board before his friends noticed he was missing.
Conditions in the lake were not safe for divers to search for the man over the weekend.

Game wardens also report two deaths on Grapevine Lake, two more at Possum Kingdom Lake, and one each at Joe Pool and Eagle Mountain lakes.
Two of the seven victims are children. Both were swimming in areas designated as swim areas at Joe Pool and Possum Kingdom lakes.
"Sometimes [in] these areas that look safe, there can be drop-offs," Modgling said. "There can be holes in the beaches that will have deeper water; they'll have ledges that drop off into deeper water."
Wardens said some of the common factors in drowning are fatigue, boating all day, alcohol use, not knowing how to swim, medical conditions and not wearing life jackets or flotation devices.
None of the victims in the seven deaths over the holiday weekend were wearing life jackets.
"Get your life jackets on and take care of yourself," said Modgling, adding that a body of water with depth never forgives a mistake.
