rainfall reduces inflows.
Conditions 9 to 12 define the minimum and maximum allowable lake levels for winter
and summer periods, specify the required spillway gate settings during a high lake
level, and allows for some flexibility in lake levels to allow for a short term electricity
shortage. When such a shortage occurs, the consent holder is required to notify

data were sorted into arrays for each individual year, and then ranked from the highest to
lowest values. After discarding the highest 5 (1) percent of the ranked values for each year
the next highest values for each year are the 95th (99th) percentiles
In this report the 95th (99th) percentiles of daily maximum gust speed will be called the
‘extreme intensity’. The frequency of daily maximum gust speed exceeding the 1972-2006
mean 95th percentile rainfall values will be called the

• Remember that waste solvents can be recycled
• Store all paints, thinners and other liquids under
cover to prevent rainfall washing out pollutants
• If liquids must be stored outside, keep lids and caps
on containers and use a secure area to avoid
vandalism
• Keep all areas exposed to rainfall clean, and keep all
wastes out of stormwater drains
• Dispose of all waste via the sewerage system or a
commercial waste contractor.

climate change out to 2100, would use an increase in peak flood flows of
approximately 20%. This is based on the latest NIWA report prepared for MfE (HIRDs V4). That report states for every
degree of temperature increase there is a corresponding 10.1% increase in rainfall (this is called the augmentation factor).
Using the RCP6 climate change scenario out to 2100 (the mid-range CO2 emission scenario) this gives a 2.0-degree
temperature increase or an equivalent increase in rainfall
undertaken within three days following significant river
freshes. However, occasionally sampling was affected by localized rainfall and
elevated river flows. An additional seven samples were taken at five of the beaches
(Onaero, Fitzroy Ngamotu, Oakura and Opunake) regardless of weather conditions for
the purpose of MfE monitoring (as discussed in Section 3.3.1). All results within this
report are presented and discussed on a site-by-site basis for the sampling period. The
