Rivers and lakes of Ireland

The main river in Ireland is the River Shannon, 386 km (240 mi), the longest river in either Ireland or Great Britain, which separates the boggy midlands of Ireland from the West of Ireland. The river develops into three lakes along its course, Lough Allen, Lough Ree, and Lough Derg. Of these, Lough Derg is the largest.
