The sediment pond is all mucked out. I just need to "pretty it up" by picking up 8 or 10 five gallon buckets of random clods. While I have it empty and dry, is there some way to keep it from being so muddy again short of lining it with tarps? The bottom is all hard clay, and so are the sides, but the sides are covered with a thin layer of pulverized clay from tractor driving.
