including loss of gate control, the scheme operated with few major issues. In comparison with
previous monitoring years, compliance with residual flow requirements was high, continuing on from the
significant improvement noted in the 2014-2015 monitoring period. Management of the level of Lake
Opunake improved from the previous period, as maintenance works and changes to operations led to a
reduction in the rate of water lost during station shutdowns. Unfortunately, the maintenance works required
resources.
1.1.4 Evaluation of environmental and administrative performance
Besides discussing the various details of the performance and extent of compliance by the Company, this
report also assigns them a rating for their environmental and administrative performance during the period
under review.
Environmental performance is concerned with actual or likely effects on the receiving environment from the
activities during the monitoring year. Administrative performance is concerned with the
the Council, which is the body
responsible for managing the asset.
1.3 Duration and review of the Plan
The duration of the Plan is ten years from the date of formal preparation and acceptance by
Council. This Plan has also been prepared with a 30-year time horizon. Maintenance costs
and rates are current to June 2020.

The Plan will be updated, after the proposed capital works are completed and then reviewed
regularly. A backup system allowed the collection of a limited range of critical data, which allowed
Trustpower to continue operating the scheme in line with other conditions (e.g. residual flows, race water
levels etc.). There was only one occasion when required flow rates were not complied with. This related to a
severe weather event resulting in a high race water level but was of short duration (no more than 2.5 hours).
Compliance with flushing flow requirements was good with regards to the
