The River Poddle is a river in County Dublin in Ireland. The city of Dublin is named after a pool that was once on its course. It rises in the Cookstown area, north of Tallaght, additional ponds were added to its course when Tymon Park was formed in the 1980s and 1990s. The river flows from Greenhills into Kimmage, where it used to receive an artificial stream from the direction of Templeogue and this, the City Watercourse, carried water from the River Dodder extracted at Balrothery Weir. In the 1990s, changes were made in the Kimmage area, the line of the two Poddle flows later recombine and pass under much of the south city centre in a culvert. The final stages of the flow are complex, with related waters separating and joining. Linked flows include the Tenter Water, and the river is joined by the Commons Water from the Coombe, the present main course is itself a diversion, the Abbey Stream, of the original course, which ran further east. Nowadays, much of the course of the Poddle is in a large brick tunnel under the city streets and Dublin Castle. The confluence of the Poddle and the Liffey is visible at low tide at an opening in the Liffey walls at Wellington Quay. A large, dark pool once existed at the confluence of the Rivers Poddle and Liffey, this pool was described in Irish as dubh linn, the city name, Dublin, is an anglicisation of this Irish phrase. This historic pool existed under the present site of the Coach House, during the ninth century, Vikings established themselves as Kings of Dublin, and based their settlement around the confluence of the two rivers, upstream from the Stayne long-stone. The Poddle was known colloquially as the river Salach, or dirty river in Irish, a variation of this name, The River Saile, is used in the old childrens song Weela Weela Walya, famously performed by The Dubliners. In 1592, Red Hugh ODonnell and Art ONeill escaped from Dublin Castle through a drain into the Poddle which runs under the castle from Ship Street gate to the Chapel Royal, the Poddle was later used to provide a water defence for the south wall of the castle. For centuries the Poddle, progressively culverted, caused flooding and constant dampness in many buildings in the Blackpitts to St. Patricks Street areas. For much of time, a special public body, the Poddle Commission, operated, working to manage this.
