Ifishnow, what are you going to do with the mud that you dig out and how is it going to be moved? I have cleaned out some ponds where I cut a trench in the dam wide enough for a big LGP dozer to go through. Then I could push the mud right out the back, pretty quick and easy. Dealing with mud is expensive, figure out a good plan for the mud before anything is started. I have never had any trouble with filling in the trench afterward and making it hold. Siphoning works great if you do not need to cut the dam.
