Looking at doing something similar to my pond this fall, except the fish are already dead and most of the water is all gone. My question is, underneath the foot and a half of muck there seems to be a solid bottom, has anyone done something like this and been able to take the excavator down into the pond area to move a lot of extra dirt out? I'd like to go 10' deeper and I can't reach the middle from the edges of the pond, so I'd like to take the excavator down in the pond to do the job right, but I don't want to lose the machine in the mire either... I know every area is probably different, so maybe it's an unfair question, but I was just looking for a little confidence at trying it, or a flag off to save me from a day of trying to get the excavator unstuck... Thanks J
