not sure about your part of the country but my 5 acre lake is only 7'deep.i had to build a levee around 3/4 of my lake to get this deep,we hit sand at 4-5'so i put a levee around it to get 6-7'average.i would think that would be enough water in your part of the country to do what ever you wanted.also that is not alot of money to build a pond of that size for people in the south.i would love to have spent that amount to get a nice pond.go for it.
