Joshua Reed, 29, was kayaking with friends Saturday when they paddled into a restricted area.
That's when discharge waters released through the dam from Eagle Mountain Lake overtook them.
The groups' kayaks capsized. Everyone in the group except for Reed managed to swim out of the current and get to safety.
Reed's friends say that the outing had nothing to do with thrill seeking; they were just friends who went out for a nice time.
"He was just a go-to guy," said Jonathan Hamm, a friend of Reed's. "He loved doing everything. If he tried something and he loved it, he was hooked on it."
Jason Snook, a friend of Reed's who was kayaking with him, says a fence that separates the area was likely underwater, and they didn't see any signs that warned of the danger.
Reed's body was discovered Sunday afternoon by search crews with the Tarrant Regional Water District.
A Tarrant Regional Water District spokesman says that there are warning signs posted, but at dusk or when it's dark, they're likely hard to spot.
