Water Shortage Direction renewed for Opihi River and tributaries
A fifth Water Shortage Direction for the Opihi River and its tributaries – which includes the Opuha River and Lake Opuha
– has been amended effective from Friday March 6 for a further 10 days.
The Direction requires Opuha Water Limited to maintain a minimum flow of 2.5 cubic metres per second in the Opihi River
(at the saleyards) when the lake is below 375m and above 370.3m. This is a reduction from the existing minimum flow of
3.5 cumecs and the reduction will be implemented in stages by Opuha Water Ltd.
When the water level in Lake Opuha is at or below 370.3 metres, Opuha Water Limited shall manage a transition to natural
flows to a level of 370 metres.
For the duration of the Direction, when the water level in Lake Opuha falls below 374 metres consent holders linked to
the Opuha Dam are required to cease abstraction for irrigation from the Opihi River and its tributaries.
Notwithstanding the above, when the lake level is above 370 metres and the minimum flows specified are achieved,
restrictions on “above dam” consent holders shall be determined by the minimum flows in the waterways to which they are
tied.
Environment Canterbury has authority under Section 329 of the Resource Management Act 1991 to notify the Water Shortage
Direction.
