In 1949 the tug "Red Rock" sank in 75 feet of water in Lake Nipigon.
Diver 'Doc" Fowler was called in to raise it.
" This was a tricky job as there was no equipment with which to lift the tug and so it had to be dragged a half mile along the bottom of the lake to shore. This was done by using the winch of a tractor and two alligators hooked to the shore with their winch cables hooked to the tug. The tug was pulled onto the shore, water pumped out and then towed to Orient Bay for repairs."
