Residents living next to Lakes Te Anau and Manapouri were on alert last night as water levels continued to rise after continuing heavy rain in the headwaters.

According to Meridian Energy's website data, Lake Te Anau was at 204.513m above sea level yesterday, well above its normal operating range of between 201.5m and 202.7m.

And Lake Manapouri was at 180.040m, compared to normal operating levels of between 176.8m and 178.6m.

Environment Southland remained on flood watch yesterday as a band of steady rain moved over the headwaters of the two lakes and towards the Mataura River.

The MetService was predicting the band would move further east, dumping a further 100-150mm of rain on catchment areas until today.

Environment Southland's director of environmental management Warren Tuckey said the rain would have a "significant impact" on the region's already swollen rivers.

"We will resume flood warnings if the rainfall and river conditions reach our preset trigger levels, bearing in mind that the catchments are already saturated," Mr Tuckey said.

The Invercargill, Southland district and Gore mayors have put aside $170,000 compensation for the victims of flooding earlier this week.

Invercargill Mayor Tim Shadbolt told The Southland Times there was $170,000 in a flood relief fund for just such an event as this week's floods.

Depending on which part of Southland the flood victims lived in, they should apply for some of the money through Mr Shadbolt, Southland Mayor Frana Cardno or Gore Mayor Tracy Hicks.

The region has been drenched since the weekend, with the worst flooding in 10 years knocking out phone lines to Te Anau, prompting the evacuation of trampers, causing the closure of numerous roads and schools and waterlogging farms.

Environment Southland posted a flood warning at 5.30pm yesterday for the Waiau River which, at Sunnyside, was 3.86m above normal and rising by 137mm an hour.

• Potentially high river flows between Alexandra and Clyde have forced the postponement of an inaugural cycle event between the two towns, which was supposed to be held today.

Clyde and Alexandra primary school staff had organised a bridge to bridge cycle challenge for about 40 pupils in years 5-8.
