region’s 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 a rating as to each Company’s environmental and administrative performance during
category of
mesotrophic to possibly mildly eutrophic (mildly nutrient enriched). However, taking into
page
account the influence of suspended sediment in this reservoir, and the moderately low
chlorophyll levels, the classification is more appropriately mesotrophic. Previous trending of
this water quality data over time found a very slow rate of increase in trophic level. An update
of the trend report (for the period 1990-2014) has confirmed this very slow, insignificant rate
around the weir, one on the left abutment, and one on the right. The required minimum
compensatory flow is 400L/s.

The current maximum consented take from the Manganui River into the race is 5.2m3/s. The
rate at which flow is abstracted from the river is controlled by two vertical gates at the intake
abstraction
rate, effluent flow rate and composition, receiving water quality, odour at the plant boundaries, effluent
loadings and soil and herbage for irrigation areas. The Council undertakes inspections of the plant site and
irrigation areas. Monitoring includes effluent quality checks and inter-laboratory comparisons, water quality,
air quality and biological monitoring.
The Council’s monitoring programmes for the period under review included four inspections, 52 groundwater
and 22 surface
on the stream for the continuous measurement of flow rate and temperature.
Silver Fern Farms Ltd (meat processing plant) demonstrated an overall high level of environmental
performance.
Silver Fern Farms Ltd holds six resource consents, to allow it to maintain a dam in and to take water from
the Tawhiti Stream; to discharge to the stream and to land; and to discharge emissions into the air.
During the period under review, there were no incidents reported in relation to activities
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 Waingongoro River supports the most popular and productive
trout fishery on the Taranaki ring plain. The river is also very highly
rated for its recreational uses and values, and for its aesthetic and
scenic values. F&GNZ is concerned that the recommissioning of the
hydro-electric power station will result in unacceptable adverse
effects. Specific concerns related to: residual

2.4 There were some positives that have come out of Covid-19 one of those being that staff
can be more flexible about where they are working from. Those who are working out in
the field can start and finish their day from home. This has also given the Council the
opportunity to look at the accommodation review and revisit the needs.
