Environment monitoring requirements. The 2012-2013 programme continued to incorporate
these changes. A later consultant’s report (in 2000) re-confirmed trends (using up-dated
methodology) that the lake was phosphorus limited and remained mesotrophic. Further
trend reporting for the period 1990-2006 was provided as a component of the consents
renewal process and suggested that while there has been a very slow rate of increase in
trophic level, the lake would be classified as

Council’s 2019/2020 Annual Plan. Chairman MacLeod gave a brief background to the
process leading up today, and thanked management staff for their effort and hard
work required over this process.
Resolved
THAT the Taranaki Regional Council:
a) receives and acknowledges, with thanks, the submissions forwarded in response
to the Consultation Document on the 2019/2020 Annual Plan

the period under review. The rating categories are high, good, improvement required and poor for both
environmental and administrative performance. The interpretations for these ratings are found in
Appendix II.
For reference, in the 2021-2022 year, consent holders were found to achieve a high level of environmental
performance and compliance for 88% of the consents monitored through the Taranaki tailored

In the 2016-2017 year there were no unauthorised incidents related to discharges from any consent holders
in the Lower Waiwhakaiho area.
During the year, Downer EDI Works Ltd demonstrated a high level of environmental and administrative

collected, while Downer EDI exceeded one sample from 10. The highest result during the year
under review was obtained by one of the Fitzroy Engineering Group Ltd gauges, which was
more than twice the guideline rate. The guideline reflects a deposition rate that may cause
complaints in a residential area.
In the 2015-2016 year there were no unauthorised incidents related to discharges from any

productivity, continued to be within the category of mesotrophic to possibly
mildly eutrophic (mildly nutrient enriched). However, taking into account the influence of suspended
sediment in this reservoir, and the moderately low chlorophyll levels, the classification is more appropriately
mesotrophic. Previous trending of these water quality data over time found a very slow rate of increase in
trophic level. Updated trend analysis, for the period 1990-2018, reconfirmed the rate of increase in trophic
