That said, there is a considerable consensus that all three major trout species (brook, brown and rainbow) begin to experience some level of stress at around 68Â°F (20Â°C), with that stress increasing rapidly as the temperature rises further.
12 water temperature dictates when trout will feed and it should dictate when the angler will fish 13 water has its greatest density at 38 to 39 degrees and trout seldom hit when the water temperature is below 40 degreesfrequently taking the water temperature tells you if it s rising or falling one degreehe immediate effect of water temperature going down in the spring is trout quit feeding after the spring flood when the stream returns to normal flow the angler can find the best fishing for big trout
