The figures released by the NSW Department of Agriculture show that for the second consecutive month 99.6 per cent of NSW is in drought.

Only the Bombala region in the State's south-east remains marginally affected, representing 0.4 per cent of the State.

However, if cooler conditions are maintained and rain continued to douse the State's parched land, the drought results could be a little less gloomy next month.

Despite no move in the number of drought-ravaged areas, precious water storage levels across Sydney, the Illawarra and the Blue Mountains had risen by 1 per cent, with dam levels increasing to 59 per cent.

This was the first rise in the catchment area for more than a year.

Premier Bob Carr said while recent rains had succeeded in lifting the spirits of down-trodden farmers, giving them a hand in preparing winter crops, the State was still quite clearly in drought.

"Despite the rains, we are still in the worst drought in more than 100 years," Mr Carr said in a statement.

Mr Carr repeated his commitment to drought-affected families saying assistance would continue to flow despite the rainfall last month.

About $130 million had also been budgeted for natural disasters including bushfires and drought and financial assistance for drought-stricken families had been increased from $600 to up to $2000.

He said the Government was providing 53 separate drought assistance measures to help NSW farmers and was providing $700,000 a week on transport subsidies.

But, while the much-needed rain brought a smile to many faces, it had also lead to the death of 60 cows at Wauchope on the NSW mid-north coast after they ate highly toxic grass, which had grown rapidly after the rain.
