Not to hijack the thread or anything...but what actually kills the trout as the temperature rises? Is it purely DO content saturation points decreasing as temperature increases or something else?
As for the trout they should take to feed readily and keep them from hammering the forage. They should make perfect food for the bass.
Of course D.O. maximum saturation decreasing as temps go up has a lot to do with it but there is a limit. Trout adapted to cooler temps over thousands of years. Forcing them to adapt to temps above their normal environment is like forcing a tilapia to adapt to cold water temps. It just doesn't work.
