Pond Boss Forums POND CONSTRUCTION Building a dam amphibious excavators

I'm wondering if anybody has used an amphibious excavator to deepen a shallow pond. Looks like a great idea, but is it cost efficient? Are they readily available? Anyone have experience in this?
Thanks

The closest thing I can think of to an amphibious excavator would be a dozer with LGP wide tracks for swamp use. While excavating catfish ponds, my Cat D4D LGP worked without sinking in oozing mud that could barely support a man's walking weight. Drain the pond as best you can and call in an LGP dozer before the water starts to seep back in. I have seen a drag line sitting on barge being used to widen a river's course, but that setup would probably cost far more than its results are worth.

We've used them to remove contaminated sludge from a lagoon but I've never used them for a pond. Pretty expensive for your average pond excavation.

Chet,

My contractor rented a dozer with "swap tracks" for some of the work in the wet spots on my pond. Perhaps you can rent a swamp buggy?

Chet,
Getting rid of what you excavate would be hard.
You would practically have to be on the bank to throw the spoils onto the bank.
