Overflow from duck ponds to footpaths concerns residents
By Maurice Garvey
RECENT overflow from duck ponds to footpaths in Corkagh Park, led to council’s drainage operation workers removing a valve and constructing a temporary weir downstream.
According to South Dublin County Council, the lakes in Corkagh Park were completed in 2000 as part of a flood alleviation scheme to protect downstream Clondalkin households from flooding.

“They were designed to retain water in periods of heavy rainfall and if necessary, overspill on the neighbouring park lands without damage to property,” said the council.
Cllr William Carey (SF) asked what measures were taken to ensure there is not a reoccurrence of flooding which occurred a couple of weeks ago.
“There are concerns, particular with people in Cherrywood where the new builds are taking place, of flooding, but I am assured by the council it was a cover that was backed up,” said Cllr Carey.
Cllr Carey said work has recently commenced on widening footpaths in the park and wanted assurance that the placement of excess soil will not interfere with the flow of the Camac river.
In response to Cllr Carey, the council said the Drainage Operations Section removed the silted up non-return valve on the pond outlet and constructed a temporary weir downstream to prevent the lake emptying completely.
“There appears to be a change in the flow regime to the lakes and this present arrangement appears to be successfully dealing with this,” said the council.
“Footpath upgrade works are being carried out in Corkagh Park.
To manage costs and reduce carbon footprint excavated soil is retained in the park – with a view to landscaping it when ground conditions are more suitable. It is positioned to ensure that it will not interfere with the flow of the river and will not give rise to flooding.”
