Mildura residents have woken to flash flooding and soaked paddocks after almost 150 millimetres of rain in 36 hours.

The State Emergency Service has received more than 230 calls for help statewide since Friday, including 100 in the Mildura area.

SES state duty officer Kate Turner said call-outs on Monday morning were predominantly related to flash flooding after 4am.

"Particularly in the last 12 hours or so, we've had a big uptick in the number of flood requests for assistance that we've had, and for building damage as well from that rain that's come through," she said.

"It was a relatively settled night until people started getting up and moving around for work and noticing the kind of damage that's come through and the amount of water that's come through overnight as well."

Mildura's wettest March day

The rainfall over the past 24 hours has broken the record for Mildura's wettest March day.

A total of 83mm had fallen since 9am on Sunday, breaking the record of 65.8mm, set the day prior.

The SES said sandbags were being prepared for residents.

"In a pinch, the best thing you can do is [use] something like a pillow case and some garden soil," Ms Turner said.

"It sounds a bit silly but it really is a matter of what you can get on hand as quickly as you possibly can.

"Failing that, it's things like moving your valuables as high up as possible ... really making sure if you've got water coming towards your property, that you've got a plan and you know what you're going to do if it does get worse."

The rain is expected to ease this evening.
