I think that would be a huge expense to fill in. Yes it is doable but not sure why anyone would want to. Looks like it would be a beautiful place. I would consider filling in the small one first but to each their own. Not sure on a cost of that. It would require lots of dump trucks loads to fill that in. Then you might end up with a marsh when all said and done. I would think they would have to remove all of the muck at the bottom of the pond. They would have to truck tht offsite also. If they didnt remove the muck. I dont think you will ever end up with solid ground. I'm no expert by far guess my opinion. And welcome to the site.
