Farmers ruin another river

The Kaiapoi River is turning salty, and irrigation is to blame:

A freshwater Canterbury river is on the brink of turning into a saltwater estuary, in part due to water abstraction, new data shows.

It has blindsided some in the community and would permanently alter the river's character if the trend continued.

"The prospect of that river turning to a smelly, scum-filled seawater estuary is just totally unacceptable," Waimakariri District councillor Sandra Stewart said.


The problem is caused by farmers taking too much water from the Waimakariri River, meaning that its flow is too weak to prevent salty tidal flows from entering the Kaiapoi. The solution is obvious: reduce irrigation flows. But that means reducing farmers' profits, which was unacceptable under National. Hopefully with a different government (and a soon-to-be elected ECan) they'll be able to stop the farmers poisoning this river before its too late.
