I did one about 3 or 4 years ago for a Live stock pond with NRCS. They pay so much per yard of dirt. If you ask me its a joke. Because you have to build the pond to there requirements but they are only going to pay for a percentage of the cost. When it was all said and done I wish that I would've just payed for it 100% myself. Id bet that it would've cost me the same. But the NRCS will help you lay out a pond and give you an idea of what kinds of soil you have at different depths free of charge.
