rainfall sites recorded figures well above their
averages for the three winter months. Our site
at Patea recorded rainfall figures that were 167%
above its average amount for those months, yet
it was still the driest of our 27 rainfall monitoring
sites around the region. Perhaps you could spare
a thought for the people working in the Dawson
Falls area, as a staggering 2,723mls of rain fell at
that site over the winter period.
Congratulations to the 55 schools, 51 early
2019-2020 monitoring year, with most
commencing irrigation in late October and concluding in March. Rainfall recorded at the Council’s
monitoring locations over the summer irrigation period ranged between 85% and 114% of historical mean
values. Total usage during the 2019-2020 irrigation season, across all exercised irrigation consents was 8,835
ML. This was more than that used during the preceding 2018-2019 monitoring year, when 56 irrigation
consents were exercised, and a total usage of 6,906 ML. …

cyanobacteria were higher than in the previous
three seasons, and similar to the preceding two seasons, probably a reflection of the relative amounts of
rainfall causing freshes that scour streambeds of periphyton.

wet weather from mid July to early
August 2008 resulted in further intermittent overflows of very dilute, treated wastewater to
the stream until mid August 2008. Similar intermittent overflows were recorded after very
wet weather late in the 2009-2010 period, over a four week period in September 2010 and
again, more briefly late in the 2010-2011 period. Seven intermittent overflows, each of one to
four days duration, occurred following heavy rainfall events in the 2011-2012 period. One

The second larger pond is unlined.
The size of the pond provides storage for a 10% annual exceedance rainfall event (AEP) event. The
maximum discharge rate from the pond during large rainfall events is 1,060L/s as this is dictated by the size
of the outfall pipe (750mm). However, there is also provision for the pond to overflow via a spillway
structure to a discharge swale (i.e. bypassing the 750mm discharge pipe).
At the time of the application it was indicated that, as a
climate, with abundant rainfall and high sunshine hours, makes the region lush, green
and fertile.
Rainfall
Annual rainfall varies throughout the region. Some coastal areas receive less than 1,400 mm annually, while
the summit of Mount Taranaki receives around 7,500 mm.
Heavy rainfall events do occur and there can be extremes. In 2012 heavy rain caused a number of slips on
the coastal road around Mount Taranaki, including a large slip at Oākura that covered the road, burying a
