Flood check, Thornlands
Has Thornlands flooded?
No historic flood extent has been mapped for the Thornlands area by the state or the council.
- Redland City has been disaster-activated for 12 flood, storm or cyclone events since 2007 — most recently South East Queensland Coastal Trough, 12 - 15 December 2020.
- Nearest flood-warning gauge: Mt Cotton West Alert, Logan-Albert basin — 6 km from the centre of Thornlands.
An extent is the official maximum-inundation line for that event. "Reaches into Thornlands" means the mapped line crosses the suburb boundary — most of the suburb may be well clear of it, which is why the address check below matters. Events are listed only where the state or council has mapped this area.
