colayn,

Hate to speak for Chucky but i think he means crappie can suspend real shallow over deep water in the dead of summer. Once the thermocline sets up to say at 20ft of water, then you are wasting your time looking for crappie below 20 ft. Even though they are over top brush in 60 ft of water they may only be suspended 10 ft deep in 60 ft b/c the best oxygenated water is from 20 ft and above so you can find what depth they are suspending and catch em all over the lake by paying attn to depth of thermocline and fish. You can see the thermocline on your sonar if you have your sensitivity turned up right. Hope this helps a little. You can look for big shad schools too in summer and find em.
