from the RHA in that it
requires underwater visual assessments at 20 underwater points along the reach (four locations across five
transects if possible).
Baseline states for sediment
The NPS-FM requires all regional councils to identify baseline states for all attributes described in Appendix
2A and 2B of the NPS-FM within each Freshwater Management Unit (FMU). When compared against national
bottom lines and the relevant objectives for an FMU, baselines provide the
condition in New Zealand lakes. User Manual Version 2.

Lake SPI surveying in the Taranaki Region
In 2021, Taranaki Regional Council (TRC) engaged NIWA to survey three lakes (Lakes Kaikura, Mangawhio,
and Rotokare) using LakeSPI (Table 3, Figure 1). These lakes were the first in the region to be assessed using
this method. Lake SPI surveys were completed in November and December 2021. Detailed

Taranaki Regional Council wants the
public’s views on six key focus areas as we
look at how to meet the challenges the
region faces over the next decade.

class.
Further, as the maximum amount of periphyton biomass is affected by the amount of nutrients in the water
column, the NPS-FM also requires councils to set appropriate in-stream concentrations and exceedance
criteria for dissolved inorganic nitrogen (DIN) and dissolved reactive phosphorus (DRP) to regulate
periphyton biomass growth (Ministry for the Environment, 2020).
Periphyton monitoring in the Taranaki region
In 2018, Taranaki Regional
sites considered in this assessment is 22
(Appendix A). These sites have been used to inform the identification of draft ammonia, nitrate, and DRP
baseline states.

Baseline states for nutrients
The NPS-FM requires all regional councils to identify baseline states for all attributes described in Appendix
2A and 2B of the NPS-FM within each Freshwater Management Unit (FMU). When compared
taxa present
at a site. Note that while the NPS-FM requires QMCI as a numeric attribute state for macroinvertebrates,
Taranaki Regional Council (TRC) uses the semi-quantitative MCI value (SQMCI), which provides a similar
output and will be considered surrogate to QMCI in relation to the NPS-FM. Unlike the MCI, the SQMCI is
not multiplied by a scaling factor of 20, thus provides a smaller numerical output. This attribute uses the same
methods applied as those applied to the MCI
growth, as well as from losing oxygen in bottom waters of deep lakes.

For lakes and lagoons that are intermittently open to the sea, monitoring data should be analysed separately for closed
periods and open periods.
Lake monitoring in the Taranaki region
Prior to 2022, lake monitoring undertaken by the Taranaki Regional Council largely focused on a single lake,
Lake Rotorangi. Lake Rotorangi is an artificial lake used for hydroelectric generation and monitoring has
to
provide maps containing information that relates to
your risk identification and action selection process.
The regulations allow you to present maps in a way
that makes sense to you, providing the requirements
are met. This means you can choose any mapping
tools, the form, size, the number of maps, and the
combination of features you display on each map.
However, you should check with your
regional/unitary council if they have any guidance or
specific mapping requirements.
