… why is Lake Hawea going to be taken below its minimum level to generate more electricity?
Contact Energy will lower Lake Hawea below its statutorily imposed minimum level of 338m above sea level in the next few days, and says it will use the extra water very carefully.
But that was questioned yesterday by the chairman of Lake Hawea Guardians, who said Hawea and its surrounds would suffer for years if the lake falls to 336m.
The company does have resource consent to take the extra two metres – but only when it’s in the national interest to have reserve capacity. Hawea locals are questioning how this condition can be met if there isn’t a crisis.
Guardians of Lake Hawea chairman Grant Fyfe called on the Government to acknowledge that New Zealand faced a power crisis and to take steps to protect the lake. He said an extra 2m would provide only 20 more days of draw-off.
The guardians vehemently opposed any reduction below 338m, he said.
“Hawea is going to suffer the consequences for months or years to come from having a lower lake, but the country as a whole isn’t making any sacrifice.”
Mr Fyfe said minimum operating levels were introduced in the 1970s when the lake fell to 327m, exposing river deltas and causing constant dust storms that carried as far as Ranfurly.
This wasn’t good for the environment or the people in the area. Nor for stock and the dust lowered the quality of wool on sheep which grazed near the lake.
Energy Minister David Parker said the situation at Lake Hawea was a reminder that the environmental consequences of electricity production were borne mostly by people in small, distant communities, rather than in cities.
We know that – but why is Lake Hawea being sacrificed with the consequent detrimental effect on the environment, people and stock, if there isn’t a crisis?
