We have what appears to be floating clumps of suspended clay soil, sometimes topped with grass clippings or occasionally sprigs of green grass growing on top of the clumps, that collect on top of our 2 acre lake every summer. They begin on the shallower shoreline areas, but collect on first one side of the lake and then the other, depending on where the wind pushes them. On completely still days, the little clumps may be scattered all across the lake. Except for shoreline areas, the lake is very deep (60 ft. in the center) to hold irrigation water.

Is there any way to get the suspended clay to drop back to the bottom? Any help would be appreciated, as the clumps really destroy the aesthetic appeal of the lake!
