Welcome Dyrne,
That seems really high.
Did they give you an idea of how many cubic yards the dam would be? Ballpark cost is $3/yard
What kind of equipment they would be using? Scrapers,dozers, excavators?
Any piping system included in that cost? Siphon, Bottom drain?
What is the soil like? Lots of rock, clay, sand?
Does that include removing the trees and then dealing with all the rootballs?
