Smythe Street and Vite Vite Road at Mt Emu Creek Bridge were still closed yesterday but the worst of the flooding seemed to have subsided.

Corangamite Shire community relations manager Glen Bernoth said the creek was swollen and localised flooding could still occur.

Meanwhile, the Bureau of Meteorology forecast sunny weather today in Ballarat with some showers expected tomorrow.

The BOM expects rain in the region on Thursday with a chance of thunderstorms.

While clean-up efforts ramped up in Creswick and Clunes yesterday, emergency workers were on standby in Horsham.

Speaking from the Horsham Incident Control Centre, Wimmera police division Acting Superintendent Colin Renton said flooding was expected to begin about 8am today.

Acting Superintendent Renton said about 20 households had been contacted, to notify them of the impending flood.

However, he did not expect flood waters would severely damage properties in Horsham but said it could force the closure of the Western Highway near Dimboola.

Yesterday Powercor spokesman Hugo Armstrong said power had been restored to all but three customers in Ballarat.

Thousands of households in the region had their power cut off after the flooding.

"There's been a huge amount of work done in the last 48 hours and Ballarat has been among the worst hit in Victoria," Mr Armstrong said.

While the flooding damaged many homes, the rains replenished reservoirs surrounding the city.

Water storages were brimming yesterday, with the White Swan Reservoir at capacity, while smaller storages nearby were spilling over.

Central Highlands Water communications manager Wendy Stubbs said the Avoca Reservoir was at 10 per cent capacity at the beginning of August but was now overflowing.
