Lough Ree (Loch Rí in Irish) is a lake in the midlands of Ireland, the second of the three major lakes on the River Shannon. Loch Rí means king lake in reference to the fact that it is the largest lake on the Shannon. The other two lakes are Lough Allen to the north, and Lough Derg to the south. The lake serves as a border between counties and is popular for fishing and boating. The lake supports a small comercial eel fishery and is locally famous for its eels on wheels truck. The town of Athlone is situated just below the lake on the river, and has a harbour for boats going out on the lake.
