RAIN affected crushing at the Isis Central Sugar Mill last week with 53,135.27 tonnes being processed through the mill up until last Wednesday.
Persistent showers halted harvesting early on Wednesday, July 11, and by nightfall the factory had ground to a halt.
More than 60mm of rain fell across the region over the next five days, postponing the resumption of crushing.
Chief executive officer John Gorringe said the mill had been communicating with growers and contractors and a resumption of harvesting, albeit limited, was expected yesterday with crushing set to resume today.
"The rainfall and subsequent crushing delay is unprecedented for this time of the year," Mr Gorringe said.
"The district has a large crop to process and substantial time has already been lost.
"Harvesting is expected to be difficult and this will cause supply issues."
Mr Gorringe said field staff were monitoring the situation and would work with growers and contractors to identify dry blocks and direct suitable harvesting equipment to the areas of need.
