A couple more questions.
1. Are you wanting to hunt these birds, build a viewing-hatching refuge?
2. If you do want to hunt, how many times a season do you intend on hunting them?
3. Which type of ducks and geese are you designing for? Divers or puddlers. White geese or dark geese.
4. The lake you mentioned what type of birds are on it now. Does it hold birds spring, summer and fall? Does it hold more during the migration?
The answers to these questions will narrow down your possible design inputs. Keep in mind, for OPTIMAL waterfowl pond designs, fish should not be present, at all. Unless you enjoy eating mergansers
