Northland has a large number of small river catchments and short, meandering streams. Climate and geology influence the flow within these rivers and the seasonal variation in rainfall is reflected in higher flows during winter and lower flows during summer.
During 2008-09, rivers in Northland had above average monthly flows for nine months of the year. The months of September and October 2008 and January 2009 recorded below average monthly river flows.
