Priority Rivers 10 year Flood Extent

The priority rivers project involves the 26 river catchments around Northland identified as priorities for flood risk planning. The rivers and streams in these priority catchments pose potential threats to lives, buildings, road access, infrastructure and agriculture. Further information on our website http://www.nrc.govt.nz/Your-Council/Council-Projects/Priority-Rivers/Project-Overview/ 

The flood data shows the likely extent of river flooding during a 10-year or 100-year flood event. A 10-year flood area has a 10% chance of flooding annually, whilst the more extensive 100-year flood area has a 1% chance of flooding annually. The data is designed to raise awareness of where flood hazard areas are and inform decision-making, to help minimise the impacts of flooding in our region.

Disclaimer The flood data has been compiled using an assessment of best available information, and should give a good indication of the areas at risk of flooding. However, flood mapping is a complex process which involves some approximation of the natural features and processes associated with flooding. Before using the flood maps, please ensure that you understand the disclaimer. Download the Disclaimer (PDF, 240 KB)
