Holy shit, I don't think you're far from where my parents live. In between G.R. & Lansing?
On another note - unless it's classified as wetlands, I don't think there's gonna be fuck-all you can do about it. Wait for the McMansions to go in and then sell yours and find a different lake.
And 10K/acre? Shoulda bought it.
The lake is in Pinckney, north west of Ann Arbor. I plan to contact the Huron River Watershed council to see if they can give me any information on any protections that may apply.
As i get older I get more nostalgic and like to hang onto things from my childhood, this is one of those things.
Plus, this view is awesome
