Yes, the muck is hard to work with. Once you swing it out to dry land where do you put it. It will level and spread out in great distances from where you drop it. Or you can truck it, and that costs more.
With the dragline, all you have in the water is a bucket with cables. Not nearly as problematic to bearings. And if you have to reach really far, you can attach the cable to the opposite shore and go all the way across the pond with the dragline bucket. The dragline bucket uaually has holes near the top to let the water flow back out to the pond as it is pulled up, keeping only dirt inside. I am not positive about this, but I would think that this would allow alot of the fluid muck to spill out with it and keeping the more solid dirt inside the bucket. Thus you would be able to put it on dry ground without as much spreading out. This also lets you work in deeper water/without draining, compared to a regular backhoe/trackhoe. However, not as effective on removal of muck, but it accomplishes a deeper pond all the same.
