Wivenhoe was built to be a flood mitigation dam. Then came the bad drought and Brisbane was on serious water restrictions so it became a water storage dam after the drought broke. "No worries, mate. We've had our big flood. No need to keep space in the dam for another." So, 37 years later along comes another "one in 100 years flood."
A senior bureaucrat in the old Irrigation and Water Supply Commission told me at a heavy plant seminar that at least two dams in Qld. were built against the Dept's advice. These dams were built not to catch water but to catch votes in marginal electorates.
