I have no inside knowledge at all , but a reasonable understanding of the need to up grade the ability of dams to cope with huge rainfall events as well as earthquakes . Eildon was done and basically paid for by the irrigators by losing 20% of their sales water right new flood capability is 14.1 meters above full supply level , interestingly the record inflow occured in 1993 500mm of rain and inflows peaked at 160, 000 Ml a day or roughly 1 metre water rise . If the dam were to increase for flood mitigation it would need to drop down very quickly in case of another such event . Melbourne City area had 2 100 to 150 year probability rain events 3 days apart , water was nearly 1 metre deep flowing down Elizabeth St . Whether climate change or just the on going records the rainfall events seem to be getting larger and more frequent remember the heaviest rainfall and greatest drought statistically have yet to occur . I doubt that warragamba dam could have an increase in capacity as well as the flood mitigation
