Thanks for the input.

1) to double check my previous calculations, I used the program you recommended and came up with 1.1 acres.

2) the plan is to remove everything from the old and start new so that is covered.

3) putting in the structure while empty was the original plan but snow came early and at the rate the pond is still filling from the springs (even iced over), I am not sure it will happen. I do have a couple of diver friends that have airbags and have been told it won't be a problem to put it wherever I want if I can't do it before it fills.

4) definitely LMB and BG but I am considering Crappie after reading this from a local fish hatchery:

"..... With the exception of black crappie we do not recommend sunfish, such as bluegill, as a forage fish in northern regions. Because of the short growing season for bass in the north they are not able to keep up with much more prolific sunfish. Eventually the sunfish will take over the pond without intense management. Crappie do not spawn as prolifically as other sunfish so therefore it's easier for the bass to keep their numbers in check. Yellow perch may be another option as a second forage fish although they have been known to take over a pond now and again. Crappies and/or perch are a great option if you enjoy ice fishing."

Other thoughts on that would be appreciated from other members.

As for a dock, I would like something BUT cannot decide on a location due to the shape and the width of the dike - I did not plan well enough for that aspect. Need more though but you are correct in being easier now than later unless I make a floating system.
