Where does one find out if a particular body of water is legal to land on? Many of the small ponds in my area have 10hp rules for boats, yet float planes fly in and out. Are there any limitations for seaplane pilots in terms of landing (I always assumed there must be, but I have no idea what the source is)? I have always thought it is not legal to land on the pond behind my house as it would require you to fly low over national park land (and it has a 10hp limit), but I saw a plane doing it last night. Hmmm?
