The River Liffey is a major waterway in eastern Ireland that flows through Dublin and into Dublin Bay. It has several tributaries like the River Dodder and supports various recreational activities. The river's name comes from the plain of Kildare, where it runs, and its flow rate averages 18.0 m3/s. With dams for hydroelectric power stations and historical trade connections, the Liffey plays a significant role in Dublin's history and modern life.
