and Tallaght Community School, to come to Tymon Lane, formerly the only road for miles, linking Templeogue and then-remote Greenhills, when Tallaght was a small village. Tymon Park and after The river flows north into the western division of Tymon Park, a large public park formed in the 1980s and 1990s, where it curves northwest and then east again. It runs below both the site of the ruined Tymon Castle and the site of the later house of the same name (now a County Council depot), through an area of three small ponds, and one main one, and then crosses under the M50 orbital motorway to the eastern division of the park. In this division, after passing Limekiln Rounders Club and Clondalkin Cricket Club, the Poddle runs east. Additional small ponds, and one larger one, sometimes Tymon Lake, were added to its course here. The river reaches in this eastern section are to be redesigned, and made the centrepiece of a flood capture area, during flood alleviation works, with an Integrated Constructed Wetland also to be added. It then parallels Limekiln Road before passing under Wellington Road, going east and turning northeast by Glendown Drive. In this area, it forms the northern border of Templeogue, towards Greenhills, and then the southern border of the small district of Perrystown. Near Templeville Road, the Poddle used to receive the artificial stream from the direction of Templeogue and Firhouse. This channel, the first stretch of City Watercourse, carried water from the River Dodder extracted at Balrothery Weir in Firhouse; as of 2020, it has been dry for at least two decades. It then passes into Kimmage via Wainsfort Manor, and by Wainsfort Manor Green there is a sluice gate to manage high flow. If the water backs up, some is diverted into what is today the Lakelands Overflow culvert. Historically a surface channel, this now runs underground to cross Wainsfort Road, runs along past the Terenure College buildings and comes out at the western end of the college's lake (the lake, in turn, has a tunnel connection to the River Dodder at Bushy Park, though the lakes in that park, formerly supplied with Poddle water, are now supplied solely from the Dodder itself). The City Watercourse The Poddle's modest volume was boosted for over 700 years by a significant addition of water diverted from the River Dodder at a large weir at Balrothery
