"We were flooded once before in 1990 and we had nothing but weeds in the field after the seawater came in," he said. "The grass will be severely stunted if it grows at all after the salt damage."
The combination of high winds and a high tide produced a massive surge of water that lifted seven stone-filled gambions weighing up to 4t each and swept them across the road they were protecting. Inside the road, Mr Magner's field is strewn with kelp, stones and sand.
Close to Kilbaha, dairy farmers Patrick Blake and Joseph Bonfil are hoping the local roads will be repaired in time for milk trucks to collect their milk in early March. However, they are pessimistic about the chances of their valuable grazing land recovering.
"I'd be lucky if I get grass growing from July/August onwards with the amount of damage done so that's at least three of four grazings lost," said Mr Bonfil. "And the road is in a terrible state. The sea literally horsed stones into fields and lifted the tar off the road completely in parts."
Along the Shannon estuary, Tom Finn was one of a number of farmers flooded when the Shannon broke its embankment in 22 places. Around 300ac in the Kildysart area were flooded, with some 80ac still under water.
"When the water came over the embankment the weight of it cut away at the ground underneath it and took the bank away. Between the cost of fixing the embankment and re-seeding the ground, it could cost me €10,000," said Mr Finn.
"The OPW maintains the bank up to three miles from us at Ballinkelly but they never came to Kildysart so we have to maintain it ourselves. But we just don't have the resources form farming to fix this much damage," he maintained.
ICMSA president John Comer called for the Government to ditch its 'cap in hand attitude' about applying for funding from the EU Solidarity Fund to repair the storm damage.
"Other member states seemed to suffer no such timidity in making applications," he claimed, citing the example of flooding in Austria.
Two provinces of Austria - Vorarlberg and Tyrol - were badly hit by floods in 2005, with damage totalling €592m. The monetary damage was less than the Solidarity Fund threshold but the Austrians applied for their claim to assessed as 'extraordinary regional disasters' and they received almost €14m for the restoration of roads, embankments and the removal of trees and rubble.
"The similarities between the cases seem extraordinary to ICMSA and we'd urge the Government to seriously consider making an application along the same lines," said Mr Comer.
Clare ICMSA chairman Martin McMahon urged all stakeholders to begin planning proper flood and high wind defences for the county's farming and food production sectors.
"These farmers have to be helped financially. It's impossible for them to deal with this kind of damage on their own. There may be insurance cover but claiming might trigger exclusion of certain types of cover in future," he warned.
