DODDER FLOOD PROTECTION – BALLSBRIDGE NOVEMBER 2014
The river floods some surrounding areas from time to time, as it is too short and shallow to hold the volume of water which pours into it from its tributaries during heavy rain. The River Dodder “has a history of flooding and is known as a “flashy” river with a quick response to rainstorms.”
A flood on the Dodder in March 1628 claimed the life of Arthur Ussher, Deputy Clerk to the Privy Council of Ireland, who was “carried away by the current, nobody being able to succour him, although many persons…. his nearest friends, were by on both sides.”
The two greatest Dodder floods before 1986 occurred on 25 August 1905, and on 3 and 4 August 1931. Hurricane Charley (often spelt “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.
It has long been recognised that the problem of flooding is very difficult to solve, due to the sheer volume of water which pours into the river during periods of heavy rainfall.
