Good question about ice movement on a larger pond. Not sure what the answer is, as I have never tested this pipe idea on an 8 acre pond in Colorado.

My belief is...if the ice shifts, its likely to rotate the pipe and push it under the ice. Hopefully with the pipe still stuck in the bottom of the pond. Only one way to test this hypothesis. smile
