I was thinking about the boat house idea. I take it you're talking about something like this?

We have a Cessna 206 Amphibian so I imagine we could get it to fit. This would open up lake options down south in the carolinas again but I'd be afraid of opening the door and finding water moccasins in there!
Seaplane Pilot, thanks for the advice. I need to do more research on shoreland regulations. I know everything from Maryland and south tends to be man-made and thus requires permission from the energy/power companies to build anything on the shore so I was hoping a natural lake would help me get around this but it sounds like I'm running into the same issue
