I used to be an avid fisherman and thirty years ago I’d routinely eat every decent fish that I caught. Now days I’m strictly catch and release - I just get a bad feeling about water quality no matter what lake I’m fishing in. I don’t follow eco stuff as much as I should, but I think it’s sad we can’t trust our lakes anymore.

It’s worth looking into data if it’s available. There’s a waterway in my city that was very polluted a century ago and is locally considered to be disgusting. Recent data shows it’s one of the cleanest in the city, now. There are clean places still, but you often need to dig to find out.

In the 1980s and early 90s people didn't eat too many fish out the St. Croix because of the mercury (and other) levels. But in the 40 years since the river had seemingly cleared up really well and all the normal pollution indicators (like mercury) were low. I decided to start fishing it and eating fish from it again last year. Unfortunately they weren't testing for PFOS/PFAS till the end of last year. :|
