With spontaneous combustion the likely cause, the Mid Murray Rural Fire Service said at least 1000 bales of hay could have been compromised.
Due to the efforts of firefighters, the losses were far less.
While the exact number damaged is yet to be tallied, the RFS said it is estimated that between 50 and 100 bales were destroyed.
District officer Gerard James said it was a good result, considering the difficulties experienced.
“There was not an open space where we could break open the bales, so they had to be moved a couple of hundred metres away,” he said.
“We had excavators and loaders helping with this, and at one time we had three machines operating at once.
“The fire was pretty close to a shed, so firefighters spent all day and most of the night on scene.”
The fire was reported at 7am Tuesday, with the last excavator operator leaving the scene at 1.30am Wednesday.
The fire was officially declared under control at 7.30am Wednesday, but monitoring will continue for a number of days as the bales are expected to continue to smoulder.
Working in shifts, firefighters from Myrtle Park, Mayrung, Blighty, Birganbigil and the Deniliquin brigades assisted.
