Minister for the Environment Alan Kelly has announced the allocation of €8 million towards clean up costs associated with Storm Desmond.
Mr Kelly said that the money will be sent to the eight local authorities most affected by the flooding.
It will cover expenses such as staff overtime, plant hire and flood prevention measures.
The Minister said the final capital cost of Storm Desmond has not yet been calculated.
But damage to the road infrastructure in counties Tipperary, Limerick and Clare was by far the biggest cost.
The money will be available immediately.
Meanwhile, a Status Yellow weather warning is in operation for counties Cork, Kerry and Waterford - with between 25 and 30 millimetres of rain forecast.
The ESB is to maintain the level of water released into the lower River Shannon through the Parteen Weir at 440 cubic metres per second today.
The level of discharge was not increased yesterday either, as water levels in Lough Derg had stabilised.
Clare County Council said the water level on the lower Shannon at Springfield, Clonlara is dropped slightly.
The council also expects that the cost of the flood to date will be almost €1m.
In Athlone, civil defence volunteers have been helping to evacuate homes in some of the worst areas affected by the flooding.
Roscommon civil defence staff used a rigid inflatable boat to help an 83-year-old man from an area near Clonown.
There has also been a call for additional funds to be provided for the agencies helping to fight the floods with pumps and sand bags.
In Mayo, the council says floods in the county are receding, although there are still concerns about some southern parts of the county near the Robe River.
Offaly County Council said the situation along the banks of the Shannon has remained unchanged for the last 24 hours.
Elsewhere, the ESB is considering the situation at the Iniscarra Dam, where a decision to increase discharge levels could increase the flood risk to properties in Cork city.
However, tonight gardaí at Anglesea Road station in the city said although there was some accumulation of surface water in areas close to the River Lee, a flood alert was not anticipated.
The National Coordination group said there are encouraging signs but there is still a lot of flooding and a lot of work to be done.
Jim Casey of the OPW said levels in all parts of the Shannon have dropped and the lower Shannon around Limerick reached peak water levels on Sunday.
Met Éireann said the weather will be unsettled this week but there will be a few dry days in between the rain, which is still above average.

Earlier, Minister for Public Expenditure and Reform Brendan Howlin said there was merit to examining a single agency to oversee the River Shannon.
Mr Howlin said that there needed to be better coordination "whether that is a single statutory agency or an over-arching agency co-ordinating existing agencies, we should reflect on that".
Fianna Fáil TD Éamon Ó Cuív has said that there has been an under spend by the Government this year in money allocated for spending on flood prevention.
"That has been happening right throughout this Government, that money provided for capital projects has not been spent and they need to step up and move on the issue of flood defences," Mr Ó Cuív said.
Ministers announce series of planning reforms
Mr Kelly and Minister of State Paudie Coffey also announced a series of planning reforms with Mr Kelly saying that bad planning was part of the reason for the extent of the flood damage.
The new Planning and Development Bill would set up the Office of Planning Regulator (OPR) to investigate local authorities' planning decisions.
Mr Kelly defended the provision that the OPR would be answerable to the Minister instead of being totally independent as recommended by the Mahon Tribunals.
He said this was a "double lock" which upheld the democratic process.
Under the law the Minister would be expected to follow the advice of the OPR except in exceptional cases and if this happened the Minister would have to explain his decision to the Dáil.
The Minister also said that the government had accepted "in principle" the recommendations of a special review of local authorities' planning functions following a series of complaints against Dublin and Cork City Councils as well as the County Councils of Carlow, Cork, Galway and Meath.
This included a commitment to tighten the requirement that councils abide by their own development plans and that there is great transparency concerning consultation meetings between council officials and prospective developers.
Mr Coffey announced preparations for a new National Planning Framework next year which will replace the National Spatial Strategy.
