Ducks that land in the middle of a big pond

[Gottogo49]

Has anyone ever solved this problem. Ducks avoid the blind and body up in the middle of the pond. Thought about putting in a sunken blind out there. I did that once at another lease but it was a lot of work. We dug up marsh grass and replanted it around the blind. It looked great and worked good for one season but the wind and waves washed away all the grass and even messed up the blind anchors. Anyone ever try a scarecrow/scareduck?
