About Flood Watch

Wairau River in floodFlood Watch is an informative, easy-to-use tool to help you judge if there is a flood risk in your area. The Flood Watch map displays current rainfall, river flow and river level data from monitoring sites around Marlborough.

The Flood Watch graphs for these sites show both current data and flooding thresholds, with descriptions of what these thresholds mean, for example, at what levels particular roads might be closed or land flooded.

This means you’ll be able to compare current river levels and flows with these thresholds to get a clear idea how an event may affect you.

The graphs are designed with a fixed scale that works best during high flows and flood flows, so when flows are normal the graphs will seem very flat.

Using Flood Watch

Flood Watch uses a free Microsoft web application called Silverlight, which is very quick to download. You will need Silverlight installed on your computer to view the page. If you don’t have Silverlight then you will be prompted to download it when you open the Flood Watch Screen. For more information about Silverlight and system requirements see About This Site.

Once you open Flood Watch, the Flood Watch Help page provides information on how to use the map and graphs.
