Southwest Michigan | From my understanding (what I've been told), the pit was a natural depression that was dug out about an additional 6 feet, with spoils pushed out around it. Clay was then hauled in to form the liner. The soil is naturally well drained, good top soil with very sand subsoil. I would imagine scraping the liner up and pushing a reasonable amount of spoils back in would provide reasonably good drainage. I wouldn't plan on croping that area, but pasture it instead. If its a little wet in the spring it would be OK as long as water doesn't stand too long. As far as emptying out the good stuff, I think it will be a two stage effort. Step one agitate and pump, step two dig out whats left and dry before spreading. I think from a cost standpoint, the more that can be pumped the better. It might be worth adding water after the first round of pumping so that it could be agitated again, but I may be wrong about that | |
