As an almost daily user of MS Flight Simulator 2020 I was happy to find that someone had created detailed scenery of the Wolfeboro airport including the water runways. After flying in and out a few times I now know better how the field was positioned along the lake and what it looked like.
This is free scenery for MSFS 2020 users and easy to install. Thanks to "FlyingsCool" for creating it. The README file even contains a link to this thread (started in 2005!) for more information.:
