Summary
The walleye stock in western Lake Superior is one of the few Great Lakes walleye stocks to perpetuate itself over the past century. The stock had been lightly exploited because of water quality problems, which affected fish taste, and because there was no commercial fishery. With the opening of a new waste treatment facility in 1978, and improved water quality, walleye in western Lake Superior became more palatable and sport and commercial interests were revived.
