So the lake next to my house is NOT 'impaired' in that you can catch and eat fish from it but because of algae they have certain times that are impaired. They actively stock it and encourage fishing. Not sure why it's listed here but makes me skeptical about the rest of the data as I've only looked at one data point and it was wrong.

That map is also 20 years old. Edit: I looked at the wrong map.

  Which map? The one the link points to, which notes clearly "( Updated 1/4/19 )"?

    Oh, good point. I looked at the wrong map. I was looking at the mercury contamination map on the Wiki page; which is based on 1999 data.

I imagine it's considered safer to list anything that is impaired at times of the year as impaired, so people err on the side of being safer. That said, clicking on the specific item gives more details (sometimes with additional links), so perhaps that might explain why it's listed (or give you a clue of where to look to find out, if you're inclined)

"impaired" is the correct summary for a lake that is only impaired some of the time. I can also see the reasoning behind having 2 categories and expecting people to check the specifics for a given body of water before fishing it. Less chance for confusion and so on.
