PondFanatic, I put in a ~3/4 acre pond a few years ago with a price tag of $13,300 for the dirt guy. I received quotes for $5,000, $18,000, $22,000, $25,000, $28,000, and $32,000. The highest 4 prices included all the materials for my primary spillway. So when I selected the $13,300 quote I spent an additional $5,000 for materials. They removed 9,000 cubic yds of dirt, replaced 500 yds for the keyway and used 1500 yds for the dam. The remaining soil was piled up on site into clay and topsoil piles. We ended up hitting pockets of sand, gravel, and water so we had to dig it out and pack with clay. I had/have enormous amounts of clay so sourcing for us was not an issue. My slopes are 3:1 with a max depth of 9'
