That's right, it drops about 25' in two months. We shredded 100 bales of barley straw to make a layer several inches thick and then covered that with a few inches of clay. It's supposed to break down and plug the formation but didn't work in our case. I think the next step is to try a polymer like Soilfloc but that is a $10-15K gamble.
