August Slabs

As I stated on another thread, up until now I've only focussed on spring crappie. However, I've been stuck in Singpore since May, and I plan to do quite a bit of August fishing for slabs.

How do the fish patterns change from spring to late-summer? Are the fish going to go deeper, or can they still be found near shorline structure (brush piles, docks, etc)? I have a fish finder, but it hasn't proved that great for locating submerged structure. Do you guys know of a way to locate deeper structure?

My biggest concern is being able to locate these suspended fish. What are some of the methods you folks use?

Again, thanks for the help,
