A 69-year-old woman died after an accident at Dromineer on Lough Derg in Co Tipperary at the weekend.
The woman was returning to a boat moored at Dromineer marina when she slipped and fell into the water.
A male companion with her tried to rescue her from the water but was unable to do so, and the emergency services were called.
The RNLI at Dromineer arrived at the scene and managed to get the woman from the water.
She was brought to University Hospital Limerick where she was pronounced dead.
The incident happened at around 12.30am on Sunday, but details have only emerged as the woman's family were being informed.
