NZ Defence Force personnel have been working alongside ORC staff and contractors to block a hole alongside the Mill Creek pump station on the Taieri River stopbanks. [see www.otagocdem.govt.nz for photos of this)
Group Controller Scott MacLean said the sandbags and rock work had reduced the backflow that was threatening to undermine and demolish the stopbank, flooding the Mill Creek subdivision. “The support from NZDF personnel has made a huge difference to the response, not just at Mill Creek but right across our operations.“
The Taieri upper ponding area, inland from Mill Creek, has filled and is beginning to overtop – this is a design feature of the Taieri River flood scheme.
At Taieri Mouth, Clutha District Council staff are onsite observing the impact of the Taieri River high flows coinciding with high tides. At present there has been no reported impact on local properties.
Across the region, rain has eased and Mr MacLean said most river levels had stabilised.
There are concerns for the Northern Link fibre-optic cable carrying all the internet traffic from Waitati South, which has been exposed by wave action and erosion at Waitati. [photo attached – please credit NZTA]
