Warragamba Dam

North Richmond, north-west of Sydney, was ordered to evacuate as authorities fear Redbank dam may fail; Annastacia Palaszczuk says there are more 'high impact' ...

Let’s hope the flows fall far short of that. After a bit of scrambling, we’ve been able to confirm that the 600GL a day rate is the worst-case scenario. Back then the rate was as much as 440-460 gigalitres a day (there’s a bit of disagreement). Well, as almost a throwaway line near the end of the NSW government press conference this evening to announce the evacuation, deputy premier Paul Toole tossed in the number of 600GL.
