Boonah is the Fassifern Valley's country town, a service centre for the farms, horse properties and acreage that surround it.
Building a shed in Boonah
The Teviot Brook gauge at Boonah has recorded big floods: 8.50 m in February 1991, 8.16 m in 1976 and 7.85 m in early 2022. BoM notes that the main problem around Boonah is low-level bridges and roads closing, and Scenic Rim's flood hazard overlay maps high, medium and low hazard across parts of the township.
For a farm or machinery shed that means two checks: where the building sits against the flood mapping, and whether delivery trucks and machinery can still reach it when the low crossings are cut.
Almost nine in ten Boonah homes are separate houses and many are owned outright, which brings a mix of garages and workshops in town and hay, horse and machinery sheds on the rural blocks. Annual rainfall is a moderate 860 mm or so.
