Regional Council monitoring stations have been located to provide region-wide coverage. Telemetered sites provide a ‘real-time' picture of the state of Northland's water resources and are particularly important during periods of extreme rainfall, updating both the public and Civil Defence on the potential for flooding, and also drought conditions. In 2009-2010, the hydrometric network consisted of:
· 53 manual rainfall stations and 31 automatic rainfall stations.
· 14 manual lake level monitoring stations.
· 35 automatic water level monitoring stations.
· 7 automatic tidal water level monitoring stations.
· 8 automatic and 63 manual groundwater level monitoring stations.
In addition, the National Institute of Water and Atmospheric Research (NIWA) and the MetService operate their own rainfall and river level stations in the region.
