the ice must be thick to support it across the pond and yes, the pond must be pretty
deep. this is used in zone 4 and colder, like in Sweden IIRC. Ingrid

_After_ ice forms, pump a little water out to leave a gap between the ice
and water. This works as well as covering with plastic, but I suspect it's
a bit too tricky to try it with only 15" to work with in the first place.

I learned all I need to know about ice watching the last season of "Ice

I lived in zones 5 & 6 - the ice gets plenty thick enough. Especially if
you don't have snow (and if you _have_ snow, you don't usually have a
problem with a 15" pond freezing solid.
