Our experience is that August is a great time to fish.  Deeper?  Maybe a little but no need to get rediculous.  Usual haunts and structure during the morning and evening hours; mid lake, deeper structure during the day (16-25 ft).  Quicker presentations are typically most productive. 

LT can be trickier however.  Normally we would drop a 2oz airplane jig tipped with gulp, or a heavy spoon to the bottom in 50 feet and quickly reel up.  Hang on if you get a hook set.

I am doing exactly what you are, Dan.  Big water and hard fishing July 30 - August 6.
