Algae. There are toxic types of algae. Blue Green Algae is toxic to humans and animals. Yes, it can kill a dog from drinking it. I'd stay far away from that water unless you know for a fact it's been tested and what the cause is.

I was a part owner of a ranch that had a 10 acre lake on it and we ended up putting in recirculating pumps to make a fountain in the middle of it to keep the water oxygenated to keep the algae down as it was killing off the fish.

Maybe no legal to use anymore. It sure worked like a charm.
Not good for a pond, and any living things in it. highly toxic!

Selling agent said the owner family has fished the lake for decades.

Doesn't mean anything. They may have done catch & release. The algae may not have been there. And it doesn't mean they didn't get sick. Read up on Blue Green Algae. Nasty stuff! Many people didn't know about it a decade ago. It's in the news a great deal today.

I will be asking broker questions about the lake.

For now I would like to explore the worst case scenario: Suppose that green color is indeed from the algae and the toxic type. Is this treatable with some reasonable effort? Or will I be stuck with a Superfund site?

I really like the location and geographical situation with this body of water. I would like to bid for it if this problem is not prohibitive.

What elevation is the lake? What feeds it? How deep? What type of fish are they catching? Trout? Trout require clean, cold water with a lot of oxygen. None of that lines up with algae.

I'd be a lot more worried about algae on a pond dug into a pasture than a mountain lake.

Without having seen the landscape, I think you're worrying about nothing. Is there a battery plant or fertilizer company upstream of the pond? Or is it just the color?

In the grand canyon there lakes and rivers that color green due to the minerals and the water is fine. Algae bloom green usually looks different to me than that, that green looks like some mineral based green.

Yeah, in a mountain I don't think I'd be that worried about it.

EPA used to be an entity one didn't want taking over a body of water, especially a small one without much funds. But I understand they're not such monsters these days. Any ideas? At any rate I know some DEQ agents that have, for years, not been on "witch hunts", as they say, as they used to be in years past.
