The Ballina Local Government Area (LGA) is located on the North East Coast of NSW. The main township of Ballina is located at the mouth of the Richmond River. The Ballina LGA is affected by flooding caused by a number of reasons including:
The ocean tidal conditions during flood events add another level of complexity because higher levels result if the flood peak coincides with the top of the tide. In floods larger than the 1% AEP, substantial parts of Central Ballina would be inundated.
Although floodwaters from the Richmond River spill into the lower lying areas of Ballina Township, the extent of flooding from this source alone is minimal. Flooding from tributaries of the Richmond River - North Creek and Emigrant Creek, contribute a greater risk to Ballina than the main channel.
Knowing the flood potential of where you live, work and visit in the Ballina LGA is important to keeping yourself, your family and others safe during floods.

Ballina CBD is affected by tidal flooding from the Richmond River on extreme high tides of 1.8 m or more. Salt water is likely to affect some streets in the Ballina CBD, in particular Tamar Street.
Flash flooding can occur during very heavy rain in conjunction with high tides.
Please avoid driving through any water that is over roads as this can cause a wake that can cause water to enter into low lying premises and cause damage.
Low lying areas, including local roads, in North Ballina and Cumbalum area can be affected by Flash flooding. Floodwater can cover the Tamarind Drive from north of Ballina and Cumbalum to and including the interchange roundabout under the M1 highway.

Flooding in these areas can be deep and very dangerous. This is especially the case when there is a high tide combined with heavy rain periods.
Ballina North and Cumbalum will flood again. That's a fact!

When a Prepare to Evacuate - Watch and Act is issued
When a Prepare to Evacuate - Watch and Act is issued, you should prepare to evacuate. Staying inside a house, even one which you think is high enough, may be very dangerous. If you are warned to evacuate it is always safest to move to a location away from the flood affected area before floodwater arrives.
