The River Dodder is one of the three main rivers of the Dublin region in Ireland, the others being the Liffey, of which the Dodder is the largest tributary, and the Tolka.
The Dodder's main tributaries after Glenasmole, in and prior to which many streams join, are the Jobstown (or Tallaght
) Stream, the Owendoher River and its tributary the Whitechurch Stream, the Little Dargle River (with Castle Stream and other tributaries), the Slang or Dundrum River, the Swan River (or Water), and the small Muckross Stream.Link with the
The River Poddle, a tributary of the Liffey in its own right, was linked with the River Dodder from Balrothery Weir, just north of Firhouse, from the 13th century. This link formerly provided much of Dublin City's water supply. Known as the "City Watercourse," it ran through part of Templeogue. It was partly piped in the mid-20th century, and the connection was later broken by housing development. All that remains now are a small channel from the weir, dead-ending less than 100m from the weir, and some unseen underground flows.
Fish And Angling:
Fish present in the river include brown trout and sea trout. The fishing season is opened between 17 March - 30 September, and best fishing locations are Rathfarnham Road, Dodder Road Lower, Miltown Road and Churchtown Road Lower. To catch sea trout on this river it is best fished in September at night when the river is in spate.
The Dodder is home to many water-bird species including mallard, grey heron, kingfisher, dipper, coot, moorhen, grey wagtail and mute swan; the sparrowhawk nests in the trees lining the riverbanks. The fox is common along the riverbank and the badger and otter have also been seen.
