That is interesting. One of the local doctors, about 20 odd years ago developed an under water chain saw and started harvesting rainforest trees that had been submerged when Tinaroo dam filled up. Water resources stopped him because he was destroying the under water habitat. I had the opportunity to see some of the cedar harvested. The part of the trees that were below the light level were in excellent condition, the upper portion was badly decayed. When the water level dropped to 23% some years back, there was a scramble to harvest the old fence posts and stumps that were exposed. There was a great scream from government departments as a result. Seems a waste to just let good timber rot under water.

Now that is quite interesting.

It was a very interesting show, but with the cost of the retrieval the timber pricing will surely be high.....

Far too many ignorant administrators and far too little clearly thought out policy.
We get fed much the same bull-tweet here.
There are salvage policies in Eastern Canada for old growth logs which have sunk in a thousand
millponds. Possibly that's a difference. There's still too much wood here in BC to fiddle with whatever
has sunken but you people have some prize stuff to fish for.

I worked with a compressed air chainsaw in about 6m water, sawing off derelict dock and bridge pilings
in the summer of '63 or '64. Kind of neat to finish the cut and ZIP!!!!! the post log is gone!! Some other jerk's
job to snag the pole and drag it away.
