Perch too, Steelhead trout, Coho Salmon..
This could get really, really bad. I wonder if there is a shelf-life for the toxins? (I would say 1/2 life, but I’m not really sure what words to use), but soon the algae will be all dead, but for how long will the toxins be reactive? As long as there is water in the lake? Still deadly in the silt? Could be an entire cycle of life a dead zone in that 1/3 of the lake. The “middle basin” is supposed to be the best fishing of walleye?
