Welcome Guest

The West Coast Regional Council provides a flood monitoring service for six rivers on the West Coast: The Karamea, Mokihinui, Buller, Grey, Hokitika and Waiho Rivers. This service uses a network of rainfall and river level recording stations. These transmit information via radio signal or cell phone network to the Council's computer database.

Radio sites call in 3 hourly under normal conditions, though this frequency may be increased during weather events or when a site has gone through a stage alarm.

Sites using cell phone network communication call in new data every 5 or 15 minutes under all conditions.

The website is continuously refreshed with new data once it arrives in the database

Data is not updated in real-time, there will always be a time lag - the length of this lag will depend on the communication pathway from the site and what call in frequency the site is currently set to.

Use the navigation tree on the left to browse the available data and view maps, notes, images, statistics and plots.
