Editing River Dodder (section)

===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.
