Back in 1914 there was a power station at the top end of Burke Lake. The water from Gowganda Lake was carried by a wooden pipe 20" in diameter made of wooden staves and held together by steel rings. This provided electric power to the Miller Lake-O'Brien mine. Some of the remains of the concrete platform is still at the top end of Burke. Here are some pics and an old pic of the station.
The old pic is from Temiskaming Treasure Trails by Peter Fancy Volume 8
