Last week, figures from Melbourne Water's 130 data stations showed Clayton was in the top 10 for most rain in the south eastern suburbs from June-August (181millimetres).

However, Melbourne Water manager of water supply, John Woodland, said recent heavy rainfall came after an "exceptionally" dry six months which reduced the amount of water to less than half of the 30-year average.

He said recent rains had helped catchments recover from their second driest start to the year on record.

"Winter rain had a modest impact on storage levels, which rose from 26.3per cent to 28.4per cent.

"These back-to-back rain events are good for neighbourhood gardens because they soak the soil right through.

"It's a similar scenario in the catchments. Only when the soil is saturated from repeat rain events do we get the run-off required to make our storages rise. These figures are similar to what we saw in winter last year and they show how changing climate patterns are impacting the ability of our dams to recover as they did in the past."

Berwick received the largest amount of rainfall (230millimetres) followed by Cranbourne (207millimetres).
