So with the water levels at record highs, how will that affect fish migrations (if you call it that)? It would appear that fish would be able to swim into areas they haven't been able to before. Like from 3rd bay to swamp off sag. That's normally a portage, but now you can paddle through. I would assume it's probably similar between red rock bay, and red rock lake, etc.

So would more fish swim into swamp from 3rd bay, or would more fish leave swamp and head into 3rd bay, or not much difference? I would think in some cases, the fish may spawn in areas they haven't before.

Will it hurt spawn? If they travel up rivers, and spawn in areas that will soon be dry, will that hurt things, or do the eggs hatch quickly enough, that receding water won't affect that?

Any fisheries people/ biologists that have any feedback on how high water might affect things (good or bad).

Good questions.
