Floods are the most common Civil Defence emergency in Otago. Our communities often experience flooding from rivers and streams. We can also get significant surface flooding after intense localised rain - for example in a thunderstorm. Flooding occurs at any time of the year. During major coastal storms, the sea can cause flooding of low-lying areas all along Otago's coast.

The Otago Regional Council has a monitoring network that tracks rainfall and river flows from storms. The ORC flood management team also works closely with forecasters to predict and model the impact of rainfall. They send warnings to affected communities, the media, and local Councils to help those at risk. However as many waterways can flood in just an hour there may not always be time to issue a warning.
Flooding threatens lives, home and personal property and transport routes may be closed for extended times due to damage from floodwaters.
Assume that you may have to cope with a flood at some point.
Inform yourself about flood risks by contacting your local council, especially if you are new to the area.
Find out about any previous flooding and whether high water would be in your home if the worst recorded flood event happened again.
Consider building some form of storage that is protected from flooding.
If sandbagging your property is a viable way of stopping floodwaters entering your home or business, it's a good idea to learn how to do this before you need to do it for real. Click here to access a useful guide.
The Otago Regional Council's Flood Manager is responsible for issuing flood warnings. Flood warning alerts and information on Otago river and rainfall levels can be viewed on the Water Info site.
