Gmax welcome to pond boss, glad to see another trout pond owner.
Have you taken temps of the pond during the summer?, I'm sure your aware of the temperature max. of trout.
Having a 24 ft. depth is a good start but also how much inflow can you count on during the summer.
If the oxygen and temps are ok I don't see any problems with brookies and rainbows together, I've had those 2 plus browns together and they all grow well.
Besides your natural forage are you going to feed trout pellets?
