THE RIVER SLANG – THE DUNDRUM SLANG OR THE DUNDRUM RIVER
Please correct me if I am wrong whey I say that the stream flowing through the green space in my photographs is the River Slang
The River Slang , also known as the Dundrum Slang or the Dundrum River, a tributary of the River Dodder, is a stream which rises on Three Rock Mountain, County Dublin. It is in the jurisdiction of Dun Laoghaire-Rathdown County Council.
This is new to me. I got off the tram at Windy Arbour and walked along St Columbanus Road which I never visited before and then I came across what could be described as a linear park on the banks of a small stream and I could not decide if I was in Dundrum. Clonskeagh, Milltown or Dundrum. Why Clonskeagh? Because Our Lady’s National School had a sign showing its address as Clonskeagh.
I asked two people who I met on my journey and one said Dundrum and the other said Milltown [the property foe sale advertisements appear to agree]. Later a friend told me that legally it is in Rathmines Great which came as a surprise but according to my friend Rathmines Great is in the Electoral Division of Dundrum, in Civil Parish of Taney, in the Barony of Rathdown, in the County of Dublin.
From Three Rock Woods on the northern slopes of Three Rock Mountain, the Slang flows down through Ticknock, passing Ballinteer north to Dundrum, where it (sometimes known this far as “Ticknock Stream”) receives the Wyckham Stream, and then loops east, north, and west, coming to a mill pond north of the Dundrum Town Centre retail complex. The Slang then runs north via Windy Arbour and subsequently joins the River Dodder at Milltown, near the Nine Arches viaduct, now used by the Luas.
The small Wyckham Stream, joining from the west, is a natural tributary, visible on early maps, but was later connected to the Little Dargle River, further west, to take some of the flow of that river into the Slang, to increase the supply for powering of mills.
Today there is a walk made by the County Council from south Dundrum to Marlay Park, along part of the Slang, the Wyckham Stream, and part of the Little Dargle.
