Permit required for seasonal boat lift?

[bilproject]

Dug in boat houses do not effect existing lake bottom and in fact create more lake habitat. If construction is done properly little or no damage is done to the lake bottom.

I've heard that some people actually float them into deeper water and sink them below where they would be affected by the ice then raise them again in the spring. I thought that was a pretty clever.

Might be a clever idea but is illegal as " seasonal boat lift" must be removed from the water for at least 5 months to be seasonal.
