I was actually going to take some dirt from the top of the ravine and push it that way towards the dam. It will be a skinny pond but a long one. But it will have quite a bit of depth to it I thought on the end where I was going to put the damn I could get an excavator and dig a lot of that out deeper and put it up there which should take care of the root problem from leaks? I will have a dozer here next weekend but I was concerned it may be a little too wet to get down in there. I was going to try to do most of the work from the top and the sides of the ravine. I even wonder how much the leaks will matter since I have several springs feeding it.
