Advise on tomorrows' trip?

Water Clarity: Stained

Water Temp: 85ish

Weather: Sunny; sunrise: 0640; temp: 75; temp at noon: low 90s

Method of fishing: 0700 launch from a boat w/o a depth finder

Attached is a map of lake numbered with best spots:

1) Shallow area (3-10ft) with standing timber. Longer shade time with tree cover along the eastern shoreline. (I've fished here twice with no luck, however, I have seen some decent size bass jump in the morning hours.)

2) Points where I have caught smaller bass on crankbait (most productive area for me so far this summer). The bottom is composed of areas of mud, some with small rock cover, and I believe a very small/short grass bed (however I have truble finding these areas since I'm new at this). The shore line is shallow and then goes to about 20ft 50 meters from the shoreline.

3) "The Dam" (no running water or current created) with rock shoreline, and some rock covered bottom areas. Goes shallow to deep very quickly here. Not sure depth but would say 20+ easily. There is also standing structure from a small bridge that leads to a concrete box thing that's in the water. (I think this would provide a good ambush spot, and quick access from shallow to deep, plus the western side of this box would allow for cooler water temp as it's shaded from the sunrise).

4) Very shallow standing timber, roughly 3-6ft of water. Have caught only one bass, roughly 2lbs, around the timber, and I have been back there a few times.

I was thinking of trying by area #3 when I first got there in the morning, since I always start by area #1 with no luck.

How would you attack this lake?
