Sonya Loose should be able to provide more information about this lake.
I am glad to see that you are taking the correct first step by investigating information about a lake. You can always change your property, but it usually takes State or Federal intervention to make changes in a lake.
To help, if you could submit an answer to your own question with some specific topics that will help any other agents who come across this question. I provide my clients with several websites so they can research information about any lake in Michigan prior to purchase.
