places they flooded to make hydro dams...not sure how many of those places there are, but i know some exist. in the great lakes there's companies that drag up logs that sunk off of booms decades ago. the cold water keeps them preserved.

y not cut the d*mn trees before you flood the place!!! prolly too many tree hugging hippies to let that happen!!!:greenchainsaw: so if they flood the place and then they go back in and use 3 times the equipment to get the logs out that is better??? =DUMB!! i can understand the stuff with the Great Lakes-to me that is neater than crap.

cool

Looks pretty cool, but i think i'd miss being behind my saws suckin on sawchips and exhaust. At one point in my shortlived life i was a lifegaurd but for logging i'm still pretty much a land lubber.

pneumatic saws have been developed for under water cutting. I have this danarm saw in my collection that can be used under water (according to specs, I have no intention to use it )

There's a large man-made lake in Brazil that was flooded by the government before private companies could log the timber. Since the 80's they've been underwater logging. Initially, a diver would go down to the bottom (about 175 feet) and cut the trees using a hydraulic saw. After a few of the trees rocketed to the surface and destroyed a few boats, they developed a robotic, hydraulic arm that reaches down and holds the tree in place while cutting it. Then it carefully brings it to the surface.
