First they are coated in copper, and second nobody bakes pie crusts at a temp that would cause zinc to offgas and third zinc fever is not a big deal unless you're breathing a bunch every day.
I am not sure if they still plant fish at Crater lake. If you have spent much time fishing you will pretty quickly learn that almost every accessible lake in the US is regularly stocked with fish.
I would say the "native" freshwater fish population is so decimated at this point that if you want to catch something you either seek out inaccessible places that have seen little human contact, or you follow the fish plantings and catch planted fish. The idea of a lake that thousands of humans regularly access having a healthy ecology seems far fetched.
They do not stock the lake anymore, no. The fish currently in it are considered invasive by the park and there are no catch limits.
It's odd the article poses this as a "problem" in an article about Crater Lake, where uniquely among lakes this "problem" is most likely to just fix the other problem.
Kill all the fish in the lake and the lake is better off.
It won't selectively kill fish, it'll kill frogs, turtles, algae, and anything else that lives in the water which isn't a bacteria or archaea capable of living in an anoxic environment. Possibly also the predators of those species which live on land.

That's a bit dramatic. Frogs, turtles, salamanders, etc, can breathe air.
The only predators are birds, who can find food at any of the many other lakes in the area.
Crater Lake's geography is essentially unique among lakes that may be having this issue. There is a near-total lack of native fauna that would be affected by an anoxic event.
Does Crater Lake have any visiting ducks? If so, then there were probably fish in the lake at various points as some fish eggs are known to survive the trip through a duck's digestive system.[0]
I stopped reading as soon as I got to the word "tracking". Solar panels are so cheap it's always better to overpanel than add tracking. Then I re-read a bit and this is about adding solar panels in space constrained areas. Why would you do that? I guess maybe if some company needs to virtue signal rather than actually use the power and has a small lawn. Solar is amazing, but don't try and jam it into places it doesn't make sense.
If the mounts are not too expensive it could make financial sense to even out the curve in the mornings and afternoons, especially as more and more solar comes online the price you get for your power will be higher if generation is offset from most other solar farms.
Many (most?) grid scale PV plants use at least single axis tracking. Sure adding more panels could also increase output, but these plants are usually completed covered with panels and there is no more space to add more.
Bees or yellowjacket wasps? The first are pretty much "live and let live" the second turn into aggressive starving balls of winged hate in the late summer and early fall.
Bees make honey and pollinate - yellowjacket wasps may remove some pests from the environment, but otherwise bring pain and suffering to the unwary.
Depends on the state/city. In Minnesota with cheap electricity and not a ton of sun it's still worth it, just takes a while to recoup. In places in california you can recoup costs in as little as 2 years sometimes because the rates are so high.
I had a buddy go through the Canonical process, it's totally insane. They expect you to jump when they say, but then they may not respond for days or weeks.
I was trying to find information on this on the internet and couldn't find any, thanks for providing. Interestingly enough Copilot coding agent on github.com repeatedly could not complete css changes correctly, when I switched to Agent mode in the project IDE with Claude 3.7 it was able to complete it in one round, so I assumed that there was a different model.
