Bad weather across the country has led to a number of new flood warnings being issued.
Reports indicate there has been fresh flooding in parts of counties Kildare and Limerick while much of Co Galway and Co Cork remain submerged following heavy rainfall during the week.
Water levels in the River Liffey system are reported to be very high following persistent heavy rainfall overnight and the ESB, which operates three dams on the river, and Kildare County Council has issued a general flood warning for the region.
The ESB is not discharging water from the Golden Falls dam at Ballymore Eustace but is at the Leixlip dam which is further downstream.
Large volumes of water have also entered the river from tributaries and drains to the Liffey, the ESB said.
Gardaí said this evening the River Liffey has burst its banks at the Strawberry Beds in Lucan and the Lower Rd is impassable. There is also flooding between College Rd and the Castleknock Country Club and around Chapelizod.
Elsewhere, the ESB has said it has no plans to increase the level of water release at Parteen Weir in Co Limerick today. However, Limerick Co Council has warned of a number of low-lying areas which are vulnerable to flooding including Lucas Drive, Mill Road, Siul na hAbhann housing estate, Meadowbrook and parts of the Corbally Road .
A flood warning remains in place along the lower River Shannon affecting Clonlara, and Westbury in Co Clare. In Wicklow, the road from Roundwood to the Sally Gap is impassable at Annacarter Crossroads.
Earlier this week Taoiseach Brian Cowen hinted that the €10 million in emergency funding for those affected by the flooding crisis would be increased.
Meanwhile the Minister for Agriculture, Fisheries and Food, Brendan Smith yesterday visited flood-affected areas in Co Galway including a number of farms to assess the full effects of the past week's floods.
The Irish Red Cross and the St Vincent de Paul Society have set up special funds for financial donations to assist those affected by the recent floods.
Fine Gael Foreign Affairs spokesperson Billy Timmins today urged the Minister for Foreign Affairs Michéal Martin to examine the possibility of activating the Rapid Response Unit to give assistance to people suffering with hardship in flood hit areas.
Mr Timmins said the unit, which was established as a rapid response to difficulties that may arise overseas, would be helpful in providing help to those most at need.
"As we have seen at this time of crisis, so many citizens have been generous and courageous in offering their help, both financial and with their labour and resources, to those so badly affected. This unit could also look at coordinating these offers of funding or assistance," he said.
