In the mid 70's I had some WE that came from the Wisconsin River directly downstream from a paper mill. No way could they be made edible.
The WI river has gotten MUCH better, but still carries a stigma about it. Kind of like bass and pike with many people. My Brother caught a lot of walleye on the WI and gave away to a guy he knew. This guy was more than happy to have them until he got a bad one. Best described as being "soft" he claimed it stunk up the house, ruined his fresh oil, and from that day forward he said he didn't need any more fish from the river...
