River and Rainfall Data

Environmental data hub icon.Looking for rivers and rainfall data? Visit our new environmental data hub!

It brings together data from our environmental monitoring sites into one handy location, making it easier to access and view data about Northland’s environment.

If you regularly access our data, we recommend updating your bookmarks to the new hub.

From December 2021, this rivers and rainfall data page will be removed and you’ll only be able to access this data through the environmental data hub. We’ve left this page live for now so people have time to move over to the new hub.

Flow data

Flow data is not a direct measurement, rather is it derived from continuous water level data with an applied relationship (rating). Flow data as reported may change as flow ratings are updated by NRC hydrologists. This includes data previously displayed on this website.
