Ifishnow,
Not to steer you away from any of the good advice above or your goals, but you also may need to keep in mind ceratin things when it comes to dredging (and new ponds as far as that goes)the needs to satify our governemnt (like local, county, and state gov. as well as Depart of natural resources). Meaning - some states you need a re-dredge permit even if its only 1/4 acre. And if it's in a wetland area (and it does't have to be on your property) that may require bringing in the US Corp of Engineers. And if so you may have to haul out the dredged spoils instead of just spreading out on your other part of the land.
Just my 2 cents.
