In terms of E. coli, bacteriological water quality in the latest survey period was similar in comparison with
historical surveys. The total number of samples falling within the “Alert” or “Action” categories (31% of
samples, or 35% if the samples of the Waimoku are included) across the 16 recognised bathing sites was
slightly higher than the recorded long-term average. However, it should be noted that the “Action” category
is the only category for which swimming is not recommended. In the
overabundance of algae and aquatic weeds,
impact on the growth of sensitive species, or
even become toxic to freshwater organisms.
Five sites are monitored for ammonia, all of
which fall within band A. At these sites, ammonia
is not likely to have any toxic effect, even on the
most sensitive species. Modelling estimates
(Figure 4) however, suggest that around 66% of
rivers or streams are in band A, while 34% are in
band B.

Nutrients
Ammonia, nitrate, and phosphorus are important for plant growth, but in excess amounts can cause
problems in freshwater. They can lead to an overabundance of algae and aquatic weeds, impact on the
growth of sensitive species, or even become toxic to freshwater organisms.
One site is monitored for ammonia, and falls in band A. At this site, ammonia is likely to have little to no
observed effect on ecosystem health. Modelled estimates supports the

stormwater catchments were
clean. The Herekawe Stream was in low flow, with slight turbidity resulting from the discharge that
dissipated within 25 m. There were no visible emissions to air. An odour survey was conducted around the
site at and no odours were noted.

There was light rain falling during the inspection, however only 3 mm of rainfall had been recorded over the
previous week at the Brooklands Zoo monitoring station. Stormwater pond SV8000 contained 800 m3 of

the area and reduce ponding. The culvert over the waterway looked good and
appeared to be coping with flood events. The area where muds were originally spread
had pasture establishing. The area where muds were most recently being applied had
good contouring and bunding across three sides. Some muds had migrated to the soil
surface through natural processes; these muds were found to be weathering and broke
apart easily when handled. Ponded water around the spreading area from recent rain
