Pond construction (do it yourself dozer work).

I was wonder about doing the dozer work on a pond myself even though I have almost no experience (I�ve ran a dozer a total of maybe 2 hours - with assistance, but I am pretty good with a bobcat). I found were I could rent a dozer for a FULL WEEK for just a little more $ than it would cost me to pay someone to run a dozer for ONE FULL DAY on my place. Am I crazy, or could a normal person be capable of building a pond????????????????????

I have a friend who is an operator and volunteered arrange to get the dozer on my place and come out one day and get me started. I could take a full weeks vacation and go to town 12 hours a day for a full week. Again, am I crazy � any suggestions? Maybe I�m just having a wild hair.
