overabundance of algae and aquatic weeds, impact on the
growth of sensitive species, or even become toxic to freshwater organisms.
For ammonia, modelling suggests that all streams fall in band A (92%) or band B (8%) (Figure 4). Ammonia
is expected to have little to no toxic effect on all but the most sensitive species.
For nitrate, around 12% of streams fall within band A and aquatic species are unlikely to experience the
effects of nitrate. The majority of streams fall into band B (88%) (Figure

There are two storage ponds on the property, pond 1 has a storage capacity of 24,500 m3, and pond 2 has a
storage capacity of 19,320 m3.
The existing piggery, ponds, and irrigation areas in relation to the property are shown in Figure 1, and Figure 2

74. Stormwater runoff typically occurs immediately following rain events. The stormwater
volume depends on a number of factors, including the moisture content of the soil and
the intensity of the rain. The majority of contaminants contained within the stormwater

out of four sites fall within band A and one
site in band B. At these sites, ammonia is
likely to have little to no effect on all but the
most sensitive species. Modelled estimates
support the monitored results, with
approximately 68% in band A and 32% in
band B (Figure 4).
Four sites are monitored for nitrate, all of
which fall in band A. At these sites, nitrate is
likely to have little to no effect on aquatic
life. Modelled estimates largely

Results and Discussion
On the day that the nets were set, a localised rain event caused flows to increase in the Haehanga Stream.
This also resulted in the discharge of sediment-contaminated stormwater into the Haehanga Stream,
resulting in discolouration. Although discolouration is frequently noted in this catchment, the degree of
discolouration at sites 2 and 3 was
