The area targeted on 5 June was the Western side of the Upper Derwent catchment, that is Lake St Clair and Lake King William with the actual cloud seeding just north of Great Lake (upwind of the target area - that's how it works).
None of those storages spilled during the floods and indeed the presence of the Great Lake dam in particular reduced, not increased, flooding downstream as did pumping from Shannon Lagoon into Great Lake. The presence of Lake King William (Clark Dam at Butlers Gorge) reduced flow into the Derwent rather than increasing it.
With or without cloud seeding, in the absence of Hydro infrastructure generally the floods would have been greater not lesser than what actually occurred.
The above is my own view and does not necessarily reflect any official opinion on the matter.
But for what it's worth, the politics are such that Hydro will probably cop the blame if anything bad happens really. Someone's dog started barking, their car broke down, locked their keys in the car, too cold, too hot, too wet, too dry, power's too expensive, power's too cheap. Might as well blame Hydro for all of it really.
For those of us who know the real truth behind the whole energy saga over the past 6 months and with an understanding of Tasmanian politics, well let's just say there's a dangerous game being played here in terms of who gets the blame.
