Furnace Lough

Lake

Rainy today

Lough Furnace (Irish: Loch na Foirnéise) is a tidally-influenced, meromictic, saline lagoon in County Mayo, Ireland, located south of Lough Feeagh. It receives freshwater inflow from the upstream Lough Feeagh at the base of the Burrishoole Catchment and tidal input of saline water from Clew Bay, through the Burrishoole Estuary. The lagoonal estuary is notable for the perennially anoxic deep water in the main inner basin.
