He still has not been paid for the work he did. He completed it (so he said) about a week ago but did some other work on a smaller pond elsewhere on my land. I think I will politely insist he fix the dam since obviously it is not done and then when its done, I will pay him. I may even as that he pack it with a roller, like the previous post suggest. I would think they are fairly easy to rent, I would even pay for the rental.
