Welcome to Colchester and welcome to a regional "hot spot" for ducks and geese. Where did you move from?
If you are not familiar with Lake Champlain, you must understand that she deserves respect. Whether you are in a canoe or a 25 foot duck slaying machine, you must be aware of winds and weather when you are out there. The weather can change very quickly, even for a "small" body of water. And, of course, swimming, intentional or not, is not advised!
The State of Vermont Department of Fish and Wildlife would be a good place to start your search. They have good information on line for your to review. Public lands are open to you and we are fortunate to have several options.
Good luck, welcome and keep us posted.
