Your brown trout could have been caught or isolated between warmer water and lack of dissolved oxygen in the deeper cool water. Most of them likely died and a few might have been able to find a small cool water refuge with enough DO to survive. You won't really know how many survived until the water temperature drops into the 60's and you again see them. When the water cools you might try feeding some pellets to see if you get any trout response.
