Flooding has caused serious problems in parts of Fermanagh, as water levels on Upper Lough Erne reached their highest recorded level.
Major roads have re-opened across the county, but hundreds of farms still have land under water and many animals are cut off by floodwaters.
"It's very, very tough for farmers here", said Willie Cathcart, who farms a herd of beef cattle near Bellanaleck, where the nearby Swanlinbar River burst its banks this week.
"At this time of year we're trying to get onto the land to carry out drainage work, but we just can't take any heavy vehicles or equipment out there.
"We've had to abandon all work on our farm."
On Friday, farmers worked to try and reach cattle that were cut off by the floods.
"You just can't get to them because the fields are flooded, the laneways are flooded and all other access routes are flooded," Willie Cathcart said.
"Thankfully, though, any of our cattle that are stranded are on higher ground, so at least they're safe from the floods."
Farmers across Fermanagh have claimed the recent flooding was the worst in generations.
"I don't think I've ever it seen as bad as it is right now," Dairy farmer Bertie Swan explained.
"I have 100 acres of land and half of them are under water. It's impossible to farm right now."
More rain is forecast in the coming days, as floodwater is finding it hard to drain away.
The Met Office said it will be very unsettled over the next few days, with showers or more prolonged spells of rain blown in on gale force winds.
In the Republic, towns across Connaught and Munster face multi-million euro clean-up bills.
More than 110 soldiers in off-road trucks and flat bottomed boats were deployed to the worst hit areas, assisting rescues in Cork city and Ballinasloe.
Rail and bus services had been suspended in the county and the main Dublin to Galway road closed.
Eircom also revealed more than 20,000 customers were without a phone line in parts of Cork, Ennis, and Cavan.
