A young man believed to be a teenager died after the jet ski he was using was involved in an incident on Lough Derg yesterday evening.
Two girls who were also on the jet ski managed to swim to safety after it flipped over and threw them into the water near the Bridge in Killaloe Co Clare.
The Killaloe coast guard unit was sent to the scene shortly before 5:30 and began a search, along with the local fire brigade.
The rescue 115 helicopter from Shannon was also involved in the search.
The mans body was recovered close to the bridge later in the evening.
Cathaoirleach of Clare County Council Fianna Fail Councillor Tony O'Brien described it as a tragedy.
