Minister Simon Harris says concern is still high that more homes may flood as levels on the river Shannon peak.
The waterway is expected to reach peak levels over the next 24 hours and communities remain on alert, particularly in Athlone.
Already 50 homes across the country have had to be evacuated and more than 220 members of the Defence Forces have been deployed over the past 24 hours.
Minister Harris everything that can be done is and says the Government's future plans should help prevent events like these:
14 houses in Corbally in Limerick City were flooded last night after the Mulkeir River burst its banks and water was released from a nearby canal.
A further 100 properties were left without power, and the local school Ardschoil Mhuire was hit by floodwaters.
Newstalk's Richard Chambers reports:
Limerick City and County Council said it is experiencing on-going flooding problems in the city and county. Meanwhile the ESB has said it has increased its water discharge level in the Parteen Weir today.
However angry flooded residents in Corbally claimed they got no warning their homes were under threat.
Anthony O'Donnell's home in Richmond Park was destroyed and his pet dog "princess" drowned as the flood came through his sitting room.
Flooding on the lower River Shannon is set to peak later today or tomorrow.
Land surrounding the lower River Shannon is at increased risk, as water flow the through Parteen Weir will increase again today.
The ESB say this could lead to floods around Springfield, Montpelier, Castleconnell, Mountshannon and the University of Limerick.
Paul Moroney, who is a senior Engineer with Clare County Council, was asked if the area can cope with the increased water levels.
He said that while "we handle it in terms of putting any resource we can in the area", people choosing to stay in their homes despite the flood risk demands a lot of resources.
Eight houses and a school in Limerick City have been flooded, while in County Clare a number of homes have been inundated after the River Blackwater after it burst its banks.
In Dublin's Chapelizod last night people with vehicles in underground carparks were asked to move them to higher ground amid fears the Liffey could breach its barriers.
One of the areas still on flood alert is Athlone, and Westmeath County Council has advised water levels are continuing to rise.
"The current flooding in Athlone is having a severe effect on a small portion of the town but the effects are localised and there is no impact on the town at large", the Council says in a statement.
"All transport links, streets, car parks and commercial areas are operating normally and will continue to do so over the weekend and into next week".
Longford-Westmeath TD Robert Troy says residents are remaining strong despite the flooding.
He said "people have been coping extremely well" under the conditions, and he has never before seen such a strong level of community spirit and solidarity:
Met Éireann had issued a number of rainfall warnings on Saturday. However while there was some heavy rainfall across the country, the level was not as severe as had been anticipated.
Drier and lighter conditions are being forecast for today, with some more persistent falls to Atlantic coastal fringes.
However southwestern and western areas rain will develop overnight and will extend eastwards towards dawn, according to Met Éireann.
An emergency helpline to deal with requests for assistance from members of the public in Clare has been opened amid the continued poor weather conditions.
It is being operated by the County Council in response to the ongoing threat of flooding.
People can contact the service on 1890-252-943.
