Dairy farmers from the Macalister Irrigation District have welcomed last week's heavy rain.
After a dry season, the Macalister's irrigators bought 600 megalitres of water at the Southern Rural water auction last week.
Denison dairy farmer Graeme Anderson says many farmers have struggled with the dry summer.
He says last week's rain is hopefully a sign that autumn will be wet.
"Hopefully with the weather conditions being reasonably favourable, that'll delay that for another 10 days after that," he said.
"So yes, that'll help, long-term, more rain is needed or more water, whichever way, from above is ... much better but we've just got to keep going and hope that follows up with a good autumn."
He says rainwater makes grass grow better than irrigated water.
"We sometimes artificially apply nitrogen fertilisers, to boost growth, and when you get a rainfall it has all of that good in it," he said.
"I'm not a scientist but it seems to work very, very well, particularly if there is a bit of thunderstorm activity around."
