If your goal is to have as little vegetation as possible then make the banks drop off as steep as possible, add rip-rap rock along as much of the shore line down as far a you can afford (3-4" water depth), and over stock with crawdads.
This was not my original goal entirely, but that's what has happened at my pond. The steep banks reduce the shallows, the rock reduces available real estate on the mud floor, and the craws eat the plants and keep the water muddy enough to reduce light penetration. However, I have been culling craws to improve clarity to actually promote some plant growth.
Most of the submerged plants for the Midwest that I have read about can reside in 6 foot of water so long as the water is clear enough, water quality is good, and the nutrients are available. It all depends on your pond conditions and what plants hitch hike in.
One thing to consider is that steep banks can be a drowning hazard. The flip side is, extended shallows will fill with plant life and reduce your open water acreage.
