A good, well built, completely excavated 3/4 acre pond with 8 ft wide core trench in NW Ohio will cost $10,000 to $15,000. It will take two large dozers about 5-7 days (8hr) of work to do a 3/4 excavated pond. Variables are depth, side slope ratio, availability of good clay near the surface, stone lined around the upper 3' of depth, dirt sculpturing. Basic charges are based on cubic yards of earth moved.
