Good luck then. I remember going a few years ago, and started kicking out in my tube in the dark, and realized that I kept kicking something. Sure enough it was trout. The Oxygen level at the time was too low for them.
Hopefully the water has cooled down, so the fish are active, otherwise you may be in for a loooong day.
100 percent behind Marley on this one.
I for one, won't fish openers for SARL/Corona ever again. Come October/November, you'll see me there.
I don't know who took the temperatures of the lake, but County Flood Control Districts and Water Districts reported the air temperature in the high 80s across the board (high 60's early in the mornings), while the water temperatures for larger lake bodies are mid 70's to 80. So, as all the avid trout anglers have pointed out, fish death is imminent, unless some decide to monitor the temperature at the lake's bottom to ensure the temperature does not exceed 70 for a possible survival chance.
