Dalby experienced its worst floods since 1981 in late December 2010. The town's water purification system was flooded, resulting in water restrictions that have hampered clean-up efforts. 112,500 litres (24,700 imp gal; 29,700 US gal) of water were transported to the town of 14,000 residents. In early March 2013, Dalby received another severe flood, cutting the town in two after 122 mm (4.8 in) of rain was recorded over a few days. Flood waters peaked at 3.21 meters and a number of homes received water damage.
