pack it, roll it, repack it, re roll it, step on it, pounce on it...then cover it with some contractors mix and water it, throw in a little lime (assuming you used clay to refill), then bermuda grass this spring. put a barrier in front of area that washed out, rocks etc. also, figure out why it washed out to begin with...spill way not big enough? did you use clay to begin with or sand/dirt? do you need to raise your dam? your dozer guy should pack in some new clay (or "gumbo clay" grade.. cheaper than road quality clay and should work)..pack the new clay, then drive back and forth on it with the heavy dozer tracks...should pack it nicely. seed it as soon as he's done because i found the seed grows well when it gets partially covered down in the tracks the dozer leaves behind. if a small area...still need good packing...but may want to consider bermuda sod. just a thought. hope it helps. mark
