categories
and soft-sedimentary, volcanic acidic and volcanic basic geology. All sites that do not fall in these categories are in the default
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

inspection.
Surface water from recent rain was discharging via three of the open trenches to the coast. Several (known)
boggy areas discharging from the north trench line were contributing to ponding that was visible from the
main highway.
The Hector Place pumping station and the emergency overflow structure were also inspected and found to
be satisfactory.

An influent flow of approximately 5 L/s was occurring at the time of the inspection, the influent screen was
Site-based baseline states identified for total phosphorus are presented in Figure 3. For four lakes (Lake
Rotokawau (NHC), Barret Lagoon (VRP), Lake Kaikura (CT) and Lake Herengawe (CT)), band C applies, while
two lakes (Lake Rotokare (SHC) and Lake Waikare (SHC)) fall within band D.

illustrated in Figure 4, the
vast majority of pasture irrigation in Taranaki does take place within Zones 2, 3, 4 and 5, which represents a
10 km wide belt of coastal land stretching from Oakura to Waitotara.
1.1.7 Irrigation systems
In general there are two types of irrigation methods; surface and pressurised. The majority of irrigation
systems currently in operation in the region fall in to the pressurised category. Pressurised systems can be
further differentiated based on the method of
following REC defined types: WD/SS, WD/VB, WD/VA, CD/SS, CD/VB, CD/VA. The Default class includes all REC types not in
the Productive class.
Based on a monthly monitoring regime. The minimum record length for grading a site based on periphyton (chlorophyll-a)
is 3 years.
* The productive class is defined by River Environment Classification (REC) types, with a combination of dry climate categories
and soft-sedimentary, volcanic acidic and volcanic basic geology. All sites that do not fall in
our rivers, flow and water level
changes and riparian habitat damage.”
The breadth of NIWA’s work on freshwater gives an indication
of the complexity and range of human impact.
For example, teams of scientists are working on ways to
treat human wastewater in towns and on farms, installing
fish passages in channelled waterways, reducing the flood of
rain channelled by urban and road stormwater, calculating
downstream impacts of water take, building wetlands and
riparian strips to stop
