- River Dodder
Dodder through Rathgar
Origin Kippure Mountain, County Dublin Mouth Irish Sea at River Liffey Length 26 kilometres (16 mi)  Source elevation 763 metres  Basin area 120.8 km2 (12,080 ha) 
Course and system
The Dodder rises on the northern slopes of Kippure in the Wicklow Mountains, and is formed from several streams. The headwaters flow from Kippure Ridge, and include, and are often mapped solely as, Tromanallison (Allison's Brook), which is then joined by Mareen's Brook, including the Cataract of the Brown Rowan, and then the combined flow meeting the Cot and Slade Brooks.
In the river's valley at Glenasmole are the two Bohernabreena Reservoirs, a major part of the Dublin water supply system.
The Dodder is 26 kilometres (16 mi) long.  It passes the Dublin suburbs of Tallaght and then Firhouse, travels through Rathfarnham, Templeogue, Rathgar, Milltown, Clonskeagh, Donnybrook, and Ballsbridge, and enters the Liffey near Ringsend, along with the Grand Canal, at Grand Canal Dock.
“ The River Dodder is renowned for its quick catchment response and flashy characteristics.  ”
The two greatest Dodder floods before 1986 occurred on 25 August 1905, and on 3 and 4 August 1931. Hurricane Charley (often spelled "Charlie" in Ireland) passed south of the country on 25 August 1986. In 24 hours, 200mm (almost 8 inches) of rain poured down on Kippure Mountain while 100mm fell on Dublin causing heavy river flooding, including the Dodder in many places, and hardship and loss were experienced. 
The Dodder's five main tributaries after Glenasmole are the Jobstown (or Tallaght) Stream, the Owendoher River and its tributary the Whitechurch Stream, the Little Dargle, the Dundrum (or Slang) Stream.  The Swan River (or Water), and the Muckross Stream, are other, late, tributaries.
Link with the Poddle
The River Poddle was linked with the River Dodder from Balrothery Weir, just north of Firhouse. This link formerly provided much of Dublin City's water supply. 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
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.
