I have been trying to construct a new pond in Myakka Florida and failed miserably. I paid the first guy $2000 to come out and dig 1/4 acre pond. it took him a month to complete and after he left and the water cleared it was only about 6 feet deep. I paid a second guy to come out with a much larger machine $2000 to finish it. My pond grew by about 10 feet all around but when the mud cleared it is still only about 6 feet deep. The water table is only about 1 foot below the surface and all of the material in the ground is sand. A 4" trash pump has a hard time keeping the water out of the pond to dig it comes in so fast and I am guessing the sides of the pond are washing out filling in the center after it is dug. Can anyone offer me any solutions before I waste and more money?
