Loughareema, also known as The Vanishing Lake and Loughaveema, (Irish: Loch an Mhadhma) is an ephemeral lake in the townland of Ballyvennaght in the civil parish of âÂÂCulfeightrin, County Antrim, Northern Ireland. The lake is known for its rapid draining and filling.
The name Loughareema is an anglicisation of the Irish "Loc an Rith Amach", meaning "the lake that runs out". An alternative spelling, Loughaveema, is also used, as Loughareema is hard to pronounce in English.
The nickname "The Vanishing Lake" derives from the lake's rapid draining and filling.
