Editing River Dodder (section)

==Course and system==
[[File:Upper Dodder.JPG|thumb|Dodder in the Dublin Mountains, 2.5&nbsp;km from its source]]

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 {{convert|26|km|mi}} long.<ref name="DodderCFRAMS"/> It passes the [[Dublin]] suburbs of [[Tallaght]] and then [[Firhouse]], travels by [[Templeogue]], passes [[Rathfarnham]], [[Rathgar]], [[Milltown, Dublin|Milltown]], [[Clonskeagh]], and [[Donnybrook, Dublin|Donnybrook]], and goes through [[Ballsbridge]] and past [[Sandymount]], before entering the [[River Liffey|Liffey]] near [[Ringsend]], along with the [[Grand Canal (Ireland)|Grand Canal]], at [[Grand Canal Dock]].

There is a [[weir]] just above the bridge at Ballsbridge and the river becomes tidal roughly where the bridge at [[Lansdowne Road]] crosses it. The Dodder and the [[River Tolka]] are Dublin's second-largest rivers, after the Liffey.

===Tributaries===
The Dodder's main tributaries after Glenasmole, in and prior to which many streams join, are the Jobstown (or Whitestown) Stream, the [[Owendoher River]] and its tributary the Whitechurch Stream, the Little Dargle River (with Castle Stream and other tributaries), [[River Slang|the Slang or Dundrum River]],<ref name="SEAScoping"/> the Swan River (or Water), and the small Muckross Stream.<ref name="Sweeney">{{cite book |last=Sweeney |first=Clair L. |year=1991 |title=The Rivers of Dublin |isbn=0-9505301-4-X |publisher=[[Dublin Corporation]] |location=Dublin, Ireland}}</ref><ref name="Doyle _p23">{{cite book |last=Doyle |first=Joseph W. |orig-year=2008 |year=2011 |title=Ten Dozen Waters: The Rivers and Streams of County Dublin |edition=3rd |page=23 |publisher=Rath Eanna Research |location=Dublin, Ireland |isbn=978-0-9566363-1-7}} ({{ORCID|0000-0001-8453-076X}})</ref>

===Link with the Poddle===
The [[River Poddle]], a tributary of the Liffey in its own right, was linked with the River Dodder from a large weir, in Balrothery, north of [[Firhouse]] village, from the 13th century. This weir, variously called the City, Great, Balrothery or Firhouse Weir, facilitated the offtake of part of the Dodder flow through a sluice and canal structure, known as the "City Watercourse", which ran through part of Templeogue. 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.
