you are a moron, read past that dumb ass comment and read the ones that actually stated what it was. How about I just cut out the middle man:
Another possibility is that this could be the wind blowing a large sheet of ice into the shore. That happened at a lake near here a few years back in the spring. The ice sheet piled up on the downwind bank just like in this video. Several lakeshore homes were heavily damaged by the ice ramming into them.
Also if you do energy trasnfer calcs, you can not freeze something that has the mass of water as it moves at the average rate of speed of a wave.
And to use your own argument against you, have you ever seen frozen lakes/wakes/water of significant mass look like snow?
