Bill,
My pond builder is coming back in early to mid March depending on weather. He is bringing a tractor and box blade to smooth everything out. Afterward, we will seed and rake it in, and follow with a lawn roller. There are thousands of bermuda grass sprigs buried in the top soil that was disturbed, and now on the dam on top of the clay. By mid to late summer, most of the rye and fescue will be choked out by the bermuda if we get anything close to normal rainfall. The back of the dam has a gentle slope, probably 4 or 5 to 1.
