The water source at Ohau A is determined by Meridian Energy canal operation. It can be solely Ohau canal water, Ohau and Pukaki Canal water, or only Pukaki Canal water. This additional sample point eliminates any influence water quality in the Pukaki Canal may be contributing to the overall monitoring or the consent. MCAS has been monitoring this site for several years on a voluntary basis.

INTRODUCTION 1.1 Overview This excursion provides an overview of the geology and tectonics of the Waitaki valley, including some features of its hydroelectric dams. The excursion highlight is Aviemore Dam, constructed in the 1960s across a major fault, the subsequent (mid-1990s – early 2000s) discovery and quantification of late Quaternary displacement on this fault and the resulting engineering mitigation of the dam foundation fault displacement hazard. The excursion provides insights to the nature and expression of faults in the Waitaki landscape, and the character and ages of the Waitaki alluvial terrace sequences.

    BEFORE THE CANTERBURY REGIONAL COUNCIL IN THE MATTER OF The Resource Management Act 1991 AND IN THE MATTER OF an application by Rosehip Orchards NZ Limited filed under CRC072118 for a water permit to take and use water from the Ohau C canal for the purpose of irrigating 610 hectares approximately 7 km south-east of State Highway 8 (SH8), Twizel. REPORT AND DECISION OF HEARING COMMISSIONERS PAUL ROGERS, MICHAEL BOWDEN, DR JAMES COOKE AND EDWARD ELLISON PART B - SITE SPECIFIC DECISION Rosehip Orchards NZ Limited – CRC072118 1 INTRODUCTION 1.1 This is a decision on an application by Rosehip Orchards NZ Limited (the applicant). It is one of many decisions we have made on 104 applications by various applicants for water permits and associated consents in the Upper Waitaki Catchment. 1.2 The decision should be read in combination with our Part A decision, which sets out our findings and approach to various catchment wide issues that are common to multiple applications. References to our Part A decision are made throughout this decision as appropriate. 2 THE PROPOSAL 2.1 The applicant’s current proposal (as modified during the hearing) is to take and use water from the Ohau C canal between map references NZMS 260 H39: 842-492 and H39: 852-481, 7 km south-east of State Highway 8 (SH8), Twizel. The proposed maximum rates of take are as follows: (a) 422 litres per second (l/s) (b) 255,226 cubic metres (m3) per week; and (c) 3,660,000 m3 of water per year. 2.2 The take of water will be metered and a fish screen will be installed on the intake.

Overview of Damage Levels and Categories From the NZSOLD Guidelines, Module 2, Section 2.9 and Table 2.2, outlines the “Damage to Property, Infrastructure and the Environment”. Overview of the Ohau A Reservoir Damage Assessment Why the assessment was completed? • PIC reviews for all Meridian Dams, outlined that the Ohau A Reservoir, which has a lot of different locations for potential breach (from different embankment reach sections), and has some variable and in places unquantified consequences. • Previous dam break modelling had been completed in 2018 (14 breach locations). • The results of the comprehensive assessment was for various reasons which became clearer following the initial PIC assessment (PIC reviews/updates for Meridian assets in 2019). Overview of the Ohau A Reservoir Damage Assessment The comprehensive consequence assessment was used for: • Update and confirmation of the PIC for the various canal embankment reaches. This would supersede the estimated (qualitative to semi-quantitative) assessments to date. • Assist with future updates/revisions to Meridian Emergency Response Plans (maps and data). • Better information for other Meridian uses (such as community consultation, future consenting, insurance valuations, input to district land plan changes).
