Welcome DaRube this site can be very educational, and I'm sure everyone welcomes some new opionions to the mix.
The post that has been circulating most recently about dredging was for dredging using a suction derdge. They only work in ponds with water. I've heard people refer to any process of muck removal as dredging but it seems the two you've spoken to are not talking suction dredge work. Considering how soft and sticky the mud can be, I'd be skeptical of taking a piece of heavy equipment in there when it's in the semi frozen muck state. Muck by any other name is still muck, and a tractor or dozer buried in the mud can be a difficult chore to remove. On the up side it would make nice habitat! I'd vote for drying it out and doing as the second guy proposed.
