A man drowned in Lake Berryessa Tuesday, the second death at the lake in as many days.

Fairfield resident Tyron Jenkins, 26, was swimming to an island from Acorn Beach at about 3 p.m., according to Napa County Sheriff’s Sgt. Doug Pace.

He was about 40 yards off the shore when he began struggling. Two female friends he was with tried to help him, but he began pulling them down.

He disappeared under the water and never resurfaced, Pace said.

Sheriff’s Office boat and land units responded and called the county’s dive team.

The team found Jenkin’s body at about 5 p.m. in eight to 15 feet of water off the south end of the beach, Undersheriff John Robertson said.

He was taken to the Sheriff’s Office for an autopsy, he said.

Dive team members found Jenkins’ body within about 15 minutes of beginning their search because of a good description of where Jenkins went under from the women  and the dive team’s thorough training, Pace said.

“That’s why we train here, just for this reason,” he said. “It’s a popular place for bad things to happen.”

Jenkins’ death comes only a day after a 23-year-old Guatemalan man drowned while swimming in the Foxtail Flat area of the lake.

Jonatan Najera was also swimming to an island at the time. He and his cousin were about 20 yards offshore when he began to go under.

His cousin attempted to help, but lost grip on Najera.

Alcohol isn’t suspected to have contributed to either drowning, though the office will conduct toxicology tests in both cases, Pace said.

Jenkins’ death is the fifth drowning in Lake Berryessa so far this year.

Pace warned swimmers to wear life jackets and avoid alcohol while swimming.

“If you wear life jackets, this is not going to happen,” he said.
