The poly pipe is threaded through a couple of concrete blocks to keep it close to the bottom. Anchoring in our area is rare. Some fishing. The pipe stays in place year round.
I put a 4" poly sleeve around the intake pipe and the power line to protect it from chafing where it just lays on the rocks on the shoreline. Never had ice damage, but I note there are two nearby rocks (300-400 lb?) that the ice stole from my breakwater and moves them a little bit each year. One is now close to high and dry on the shore.

Polypipe appears to have tremendous resistance to chafing; however, I took an additional step. I took four feet of polypipe, cut it into four sections, then sliced each one lengthwise. They were snapped over the intake pipe, which allowed rotatation when struck by wakes.
Because polypipe floats (
and collects bubbles) those sections have stayed at the "rockline" for many years.
