recorded as stage height at Riminui station, in the middle of the Waitotara
catchment. This compared with 13.5m at the same site recorded in 2004 and 10.8 in
July 2006.This was the highest water level recorded since the site was installed in
1993. Riminui recorded a total rainfall of 307.5mm (226% of normal) for the month of
June, with 174 mm of that total falling over the 19-20 June period.
Despite the high levels of rain and river flow, the peak flood levels in the
public do? While NPDC works on bringing the dam up to regulation, it is recommended that residents in affected properties prepare a flood response plan for their family or staff members if a flood alert is raised, so that they know what to do in an emergency. Helpful information is available online here: getready.govt.nz/prepared(external link). All members of the public should also not approach the dam during periods of heavy rain and be careful downstream of the dam.

slopes of the Pouakai Range (Druce, 1970, cited in Neall, 2003). 150 years later a pumice
lapilli fall and pyroclastic flows covered Maori villages, inferred from the discovery of Maori
ovens (umu) beneath the deposits. In 1755 A.D. small hot avalanches occurred from
eruptions at Taranaki. Recent evidence from Platz (2007) suggests that the most recent
eruption was between 1839 and 1866 A.D., and potentially in
relation to best practice irrigation onto high and low risk soils.
1.6 Application Depth
The volume of water applied during irrigation is referred to as the application depth. Farmers will make
reference to the amount of rain in their rain gauge in mm. For example, there was 4 mm of rainfall
yesterday. This relates to the formula 1mm of rain falling on 1 ha equals 10,000 litres. Using the example of
4mm of rainfall, this would equate to 40,000 litres of rain falling on each ha of land.

The discharge site is approximately 120m long and 25m wide, and is shown in Figure 1.
Pātea Beach is an elevated site which for most of the year is dry. Rain that does fall on the site drains away
at a very rapid rate. The site does not suffer from flooding from rain or tidal action, due to its elevation.

August was exceptionally wet, with many rain-gauges collecting more than twice the typical rain for the month. The average was 176.6% of the long-term average, and ranged from 80% at Rimunui Station to 387% at Dawson Falls. Year to date rainfall is sitting between 113% (Manganui at SH3 Midhirst) and 211% (Dawson Falls) with an average of 141.7% of normal. Cape Egmont remains at around 211% of normal to date and has already received 95% of a typical year’s rain in eight months. Mean river flows
