River Poddle
Encyclopedia
The River Poddle is one of the best known of the more than a hundred watercourses of Dublin. It is the source of the name "Dublin", the city being named after a pool that was once on its course. It rises in the Cookstown area in northern Tallaght
Tallaght
Tallaght is the largest town, and county town, of South Dublin County, Ireland. The village area, dating from at least the 17th century, held one of the earliest settlements known in the southern part of the island, and one of medieval Ireland's more important monastic centres.Up to the 1960s...

Origins

The Poddle begins as the Tymon River in the Cookstown area northwest of Tallaght village, near the site of Fettercairn House, and flows east, through Tymon North, and northeast, forming the northern border of Templeogue

. Additional ponds were added to its course when Tymon Park was formed in the 1980s and 1990s. The river flows from Greenhills into Kimmage
Kimmage
Kimmage is a small suburb on the Southside of Dublin near Crumlin, Greenhills, Harold's Cross, Rathfarnham, Templeogue, and Terenure. The name "Kimmage" comes from the Irish cam uisce, which means "winding" river. The River Poddle flows through Kimmage, and flows on to join the River Liffey...

, where it used to receive an artificial stream from Templeogue. This stream consisted of water from the River Dodder

City Watercourse

The Poddle's modest volume was increased for over 700 years by the significant input of water diverted from the River Dodder at the great weir at Balrothery north of Firhouse
Firhouse

, and carried by the three kilometre first section of the City Watercourse. The ancient watercourse was, without explanation, disrupted in recent times by development allowed by the County Council, and it no longer operates.

The Tongue

The river is split at "The Tongue" at Mount Argus
Charles of Mount Argus
Saint Charles of Mount Argus was a well known Passionist priest in 19th century Ireland. He was born Joannes Andreas Houben on the 11 December 1821 in the village of Munstergeleen in the Province of Limburg in the United Kingdom of the Netherlands.

, with one third of the flow forming the second section of the City Watercourse, heading for Crumlin Road and Dolphin's Barn
Dolphin's Barn
Dolphin's Barn is an inner city suburb of Dublin, Ireland, situated on the Southside of the city in the Dublin 8, and partially in the Dublin 12, postal district. Its name derives from a family named Dolphyn who once owned a storehouse there. Surrounding areas include The Liberties, Inchicore,...

, and two thirds continuing in the original river bed. In the 1990s, changes were made in the Kimmage area, including the addition of a large fountain to the river.

Lower course

The two flows later recombine and pass under much of the south city centre in a culvert

. The final stages of the river's flow are complex, with waters separating and joining. Linked flows include the Tenter Water, and the river is joined by the Commons Water. The present main course is itself a diversion of the original course, which lay further east.

Nowadays, much of the lower 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 through a grated opening in the Liffey walls at Wellington Quay (picture below).

Water supply

The river provided an early source of water for the city as the Liffey was tidal within the city area, and undrinkable, and the other major south-side water, the Camac

 at the weir at Balrothery near Firhouse to the Poddle, to provide the greater part of the water flow. As mentioned, this connection was allowed to dry out in the late 20th century, and only a tiny part still carries water, though ample evidence of the watercourse can be seen: the sluices and channel on the north side of the Firhouse weir still stand.
