A woman in her late sixties died after falling into the water in Lough Derg in the early hours of Sunday morning.
The incident happened at approximately 12.30am on Sunday at the marina near the village of Dromineer on the shores of Lough Derg.
It is understood that the 69-year-old woman and a male companion were returning to a boat moored on Lough Derg when she entered the water.
The man attempted to save her but was unable to do so. He then contacted the emergency services.
The RNLI based at Dromineer, Lough Derg were tasked by the Valentia Coastguard marine coordination centre as was the Shannon coastguard helicopter Rescue 115, however the helicopter was stood down while en route to the scene as the RNLI had recovered the woman from the water.
An ambulance at the scene transferred the casualty to the Mid Western Regional Hospital in Limerick where the woman was pronounced dead.
