Same deal on many of the lakes here in nc and sc. If the level
fluctuates much you have to have a floating dock. If you want it
covered then the floats have to carry up that load too. So the focus
is on making the roof as light as possible. We don't see that sort of
snow load though.

The lakes in Tenn that are part of the TVA get drained down every
winter, some as much as 20'. If you go to Lake Cumberland in KY, and go
to Grider Hill Marina in the late fall, you'll back down a ramp that's
a few hundred feet long. Even the fuel dock/marina store floats. On
Lake Center Hill, I was amazed that the dock I use when we go on our
fall fishing trip was submerged, the road TO that ramp was the summer
ramp!
