Fish for all species at the thermocline

The water temp is in the mid 70's and the lake level is 544.6. The lake is dowm almost 71/2 ft. There are fish suspended down 40ft. The bite for the stripers has been on and off. Bass are hitting jigs and grubs in 10-20ft. We need some cooler weather to drop the water temp and then the bite will get better. Steve
