Katherine and rural areas flood maps

Flooding maps showing probable and possible areas of flooding for Katherine town and rural areas have been developed to show the likelihood of flood inundation corresponding to the Flood Warning Advices in Katherine. 

These maps are based on modelled extents of flooding at specific river levels caused by a 100 year average recurrence interval storm event falling uniformly over the Katherine River catchment.

Minor flood warning

View the Flooding map: minor flood warning - Katherine and moderate flood warning - Gorge Road.

This should be read along with advice issued by the Regional Counter Disaster Controller.

Before viewing the map and advice, you should take into account the following:

  • this advice is issued when the level of Katherine River at Nitmiluk Centre is at 5.5m and rising, but not going over 6.5m
  • information on this map should only be used as an approximate guide to identify the areas that could probably get flooded in about 12 hours of the issue of the advice in the town area - it also shows the extra areas that could possibly get flooded if the river continues to rise
  • the flood extent boundary is approximate only
  • no two flood events are the same, so the actual flood extent during a flood may differ greatly at some locations.

Moderate flood warning

View the Flooding map: moderate flood warning - Katherine and major flood warning - Gorge Road.

This map should be read along with advice issued by the Regional Counter Disaster Controller.

Before viewing the map and advice, you should take into account the following:

  • this advice is issued when the level of Katherine River at Nitmiluk Centre is at 6.5m and rising, but not going over 8m
  • information on this map should only be used as an approximate guide to identify the areas that could probably get flooded after the issue of this flood warning advice - it also shows the extra areas that could possibly get flooded if the river continues to rise
  • the flood extent boundary is approximate only
  • no two flood events are the same, so the actual flood extent during a flood may differ greatly at some locations.

Major flood warning

View the Flooding map: major flood warning - Katherine.

This map should be read along with advice issued by the Regional Counter Disaster Controller.

Before viewing the map and advice, you should take into account the following:

  • this advice is issued when the level of the Katherine River at Nitmiluk Centre is at 8m, still rising and more rainfall is forecast for Katherine River catchment areas
  • information on this map should only be used as an approximate guide to identify areas that could probably get flooded after the issue of this flood warning advice - it also shows the extra areas that could possibly get flooded if the river continues to rise
  • flood extent boundary is approximate only
  • no two flood events are the same - the actual flood extent during a flood event may differ greatly at some locations.
