First thing you should do is check for regulations that may govern the use of treated wood around the lake.
Many studies have been done on the effects of pressure treated wood on the environment.
To make a long story short, pressure treated wood is not recommended for marine piles due chemicals leaching into the water.
Creosote treated piles have been used for decades and studies have shown that this treatement is not harmful to marine life. This, however, is still a contentious issue. Creosote treated wood also lasts much longer than treated wood.
Some cities are moving to steel or concrete piles to avoid the issue.
Keeping your beams flush allows you to build the dock closer to the surface.
