hmmmm - not all. You wouldn't and shouldn't eat anything out of the Derwent - that's an express route to cancers of many types. The heavy metal contamination there is atrocious and bloody dangerous.
Waters around Queenstown you have to be very careful of - even now today if you head South of Queenstown on Dukes Road (the most beautiful road in the entire country of Australia IMO) - you see just as you leave town the steam on the right -------- well, you would have to be on the verge of death from dehydration to take even a sip from that one.
Water hides a lot of secrets. If you look at a map and see where say Dove Lake is - then, think of the prevailing winds and then also think of when the cold fronts come through and how the wind howls up towards Cradle - think back 100 to 150 years - what was in the air then ------ it had to drop somewhere.
The problem with the metals is - they don't go away - they fall to the bottom and stubbornly stay there. Rivers have floods - lakes don't get the wash out that rivers do.
I wouldn't trust the article either - but, there's a hell of a lot of heavy metals loose in Tassie and you cannot trust the old saying that Trout only live in clean water ------- metals can sit on the bottom unstirred - whilst our Trout bugger around catching flying things and swimming things.
