Water Safety Ireland is urging people to take extreme caution at waterways nationwide as the warm weather continues.
The appeal comes after a teenage boy lost his life after getting into difficulty while swimming in the sea in Dublin and three people and a dog were rescued from a boat in Lough Derg on Monday.
Last year, a total of 79 people drowned in Ireland. Some 1,108 people drowned in the last 10 years - an average of nine every month.
