Genesis faces $125m canal repair bill
Repairs to the Tekapo canals over the next two years will cost Genesis at least $125million.
It could also lead to hundreds of thousands of commercial salmon having to be temporarily re-homed, while a massive influx of workers will undertake the work.
Genesis spokesman Richard Gordon said the state-owned generator was lowering the lake to its minimum operating level over the next few months.
"We are preparing for the 14-week planned outage starting early January, which would be followed by a similarly long outage in the summer of 2013-14," he said.
The repairs would fix deteriorating leaks, most of which were about 8km from Tekapo A.
The Mt Cook Alpine Salmon farm on the canal would be affected during the outages.
Mt Cook Alpine Salmon chief executive Geoff Matthews said it was working through the processes.
"There will still be water in that section of the canal, it just won't be flowing."
Genesis will also undertake work on major section of earthworks on the Tekapo-Pukaki canal known as the Maryburn Fill, near Lake Pukaki.
"Due to the recent earthquakes in the South Island, we are taking a very prudent approach. Extensive geotechnical survey work has already been done in preparation," Mr Gordon said.
Genesis had also talked to the community around the upcoming influx of workers, as this could put pressure on accommodation in Tekapo over next summer.
