Ok thanks to all. Some real good advise and some great links. For what its worth maybe I could add some additional details about my new pond which may or may not make a difference?

The Pond was dug with a standard depth to extention ratio of 1/3 ie 3 foot out for one foot of water depth. (By my reckoning the plants at the perimeter of the pond should grow out from the edge maybe about 9 foot plus or minus, unless some millfoil finds it way in.)

The bottom soil type ranges from blue clay to total organic, and the sun light is from total sun all day, to mostly shade all day. The organic bottom is in the shaded area.

Does this narrow the selections any? I'm amazed at how many lilies there are!

We do have plenty of muskrats in Michigan but I have some experience in trapping them. Our winter climate is sometimes sub zero in Jan and Feb.

Thanks to all for all your help.
