RAIN is a fickle phenomena.

A farmer on one side of a fence can have a sprinkle while another is soaked.

The South Burnett had widespread rains earlier this week but their coverage has been patchy at best.

Noel Weller rotates between corn and peanuts over two paddocks north of Wooroolin.

He planted his summer crop of peanuts in one paddock while the second remains fallow due to the lack of rain.

"We got around 20mm in Monday's shower," he said.

"But the moisture's not good, it's not as wet as we'd like it to be."

He's left his summer planting as late as possible while holding out for more rain but the planting window is closing.

"You can never know but you've got to have a go; that's how we make our money.

"We put seed in the ground and hope for the best."

Further north in Cloyna, Helen Ward runs Corbertt's Creek Performance Horse, a horse training business.

They don't run stock but hold between 17 to 20 horses on their property at any given time.

Ms Ward is still hanging out for a downpour

"She's been pretty patchy," Ms Ward said.

"Water levels are not too bad at the moment, but if we don't get some soon, it could be scary."

While Ms Ward got about 21mm in Monday's shower, more is needed.

"It was just enough to brighten the grass but not enough to fill up tanks or dams."

Down south around Maidenwell, Jim Cross said Monday brought 48mm, a moment's relief for his herd of 150 breeders.

"It was really good rain but didn't make any water," he said.

Mr Cross was concerned it didn't do enough to replenish the aquifers.

"It'll freshen the feed up for a few weeks if we don't get too much heat," he said.

It's the best one-day fall since he's had since February last year, but he's having problems with an old bore and may have to cart in water if it's not fixed.

While a bore takes the pressure off, there's many farmers around him that rely on Barkers Creek as their sole supply.

"Barkers Creek was a reliable source of water until about 20 years ago," Mr Cross said.

"There's been a gradual decrease of rain and when you do have rain it's not good penetrating rain and it doesn't penetrate the aquifers."
