Wet months mean more water in Canterbury, but concerns remain

The pattern of dry winters Canterbury has experienced in recent years ended this year, with the region seeing a return to normal or even above normal rainfall levels in most areas.

That winter rain, combined with heavy rainfall in late autumn, has left Canterbury with healthy soil moisture levels as well as good flows in the rivers and streams in early spring.

But it’s not all good news as irrigation season approaches – that rainfall hasn’t been sufficient to fully make up for long dry periods in all parts of Canterbury, and groundwater levels remain low in some zones.

Seasonal snapshot shows emerging water quantity trends

Our Canterbury water this season webpage reports on the water levels in our rivers and streams, groundwater and soil, as well as the rainfall over the previous three months.

It compares these levels against the long-term median level for the same season in previous years.

The winter 2021 update showed how heavy rain that caused significant flooding in parts of Canterbury in late May helped replenish groundwater in some areas.
