Ontario is a lot clearer than when I started offshore salmon fishing in the 70's, also, the fishery back then was for Cohos, they were crazy , they would attack a dodger/fly 20 feet down and 5 feet off the ball, when a Chinook fishery started in the early 80's we quickly learned they were more boat shy. That and the improved water clarity with the proliferation of zebra mussels started the trend to more stealthy presentations like dipseys and boards off to the side
