Yes, that's it: hard to bend and floats. I weigh it down with rocks. I guess the rocks could be moved by ice and it could float to the surface.
It seems like very durable material that could take some stress from the ice.
I agree that lake water is the best (with a good treatment system).
Thanks for the comments.
