Lough MacNean (Template:Lang-gle) is a large, freshwater lake in County Fermanagh, Northern Ireland. The lake is fed by a small river which flows from Upper Lough MacNean into the lake at a bridging point near the village of Belcoo. The lake then empties into the Arney River.
The lake contains two islands, Cushrush Island is the larger of these and it has been extensively farmed, there is also Inishee or Jinny's Island which is smaller and is completely forested. A causeway was built out to Cushrush Island in the 1960s to allow animals to be moved more easily out to the land on the island.
The shape of Lough MacNean was changed dramatically during the 1960s when a major draining operation took place, the lake was used for wp:Eel wp:fishing before this but wp:dredging during the drainage process decimated their numbers.
