Dry conditions in South Taranaki caused by the current La Nina weather pattern could mean further restrictions on how much water can be taken from rivers, Taranaki Regional Council has warned. The environmental watchdog is keeping a close eye on rainfall levels, soil moisture, river flows and climate across the region, with most of the Council’s monitoring sites recording less rain than usual over the last three months.

floodwalls and stopbanks.
Floodgates to prevent floodwater travelling up stormwater pipes into the township.
Temporary barriers for use when there is a risk of flooding. The Waitara scheme is now very resilient. But there remains a small risk that damage could occur during a very large flood, which might compromise the level of protection afforded to the township. We keep a careful eye on the scheme’s performance during very heavy rainfall and occupants can expect a timely warning if we do see greater
