Water Shortage Direction for Opihi River and tributaries
A Water Shortage Direction for the Opihi River and its tributaries – which includes the Opuha River and Lake Opuha – is
in effect from Tuesday 16 October for 14 days.
The Direction requires Opuha Water Limited to maintain a minimum flow of 7 cubic metres per second in the Opihi River
(at the Saleyards Bridge) when the lake is above 375 metres.
The lake level is currently around 390 metres. The Opuha Environmental Flow Release Advisory Group, comprising
representatives from district councils, farmers, Opuha Water Limited, river users and tangata whenua, agreed to the
release level of 7 cubic metres for a 14-day period to enable minimum water release from the Opuha Dam in order to build
up water storage.
There are no irrigation restrictions in this Direction. Environment Canterbury has authority under section 329 of the
Resource Management Act 1991 to notify the Water Shortage Direction.
