Climate
With an average annual rainfall of 780 mm, the Lockyer Valley is the driest part of South East Queensland. Rainfall is highly variable and droughts are experienced regularly.
The Lockyer Valley typically experiences temperatures higher than the Brisbane region in summer, but colder in the winter. In November 2008, the valley experienced some of the worst flooding in its recorded history with farmers experiencing total crop failure. The flooding claimed the lives of livestock as well as an elderly female in the Forest Hill area, caught up in the flooding whilst driving.
This event was overshadowed by severe flooding in January 2011. The towns of Withcott and Grantham were particularly hard hit. Flood related deaths were recorded in the communities of Spring Bluff, Murphys Creek, Grantham and Postmans Ridge. Many council-owned bridges in the valley were either completely gone or partially destroyed. To repair roads and drains the Lockyer Valley Region local government area initially estimated the repair bill to be A$176 million.
In 2012, a solar powered, radar based, imaging system was installed to detect dramatic rises in creek water levels. The cameras monitor conditions from atop a five to six metre high pole to avoid damage during floods. An LED spotlight is used to take photos at night. When a flood event is detected the system enters a mode where images are taken more frequently. Real time data is transmitted to the council's disaster centre. The council spent $40,000 on the system.

Famous quotes containing the word climate:
“Then climate is a great impediment to idle persons; we often resolve to give up the care of the weather, but still we regard the clouds and the rain.”
—Ralph Waldo Emerson (1803–1882)
“Certainly parents play a crucial role in the lives of individuals who are intellectually gifted or creatively talented. But this role is not one of active instruction, of teaching children skills,... rather, it is support and encouragement parents give children and the intellectual climate that they create in the home which seem to be the critical factors.”
—David Elkind (20th century)
“When we consider how much climate contributes to the happiness of our condition, by the fine sensation it excites, and the productions it is the parent of, we have reason to value highly the accident of birth in such a one as that of Virginia.”
—Thomas Jefferson (1743–1826)
