oops! forgot to mention i have no way to bring in a dozer - the home and pond is built on 5 ac and in the center. the home and pond is surrounded 360 degrees by trees and brush, you cannot see this place from anywhere. and of course i already have sodded around the pond plus landscaping. this is why i am more leaning to liner or well. i will do bentinite first if you think its more feasable with desired result.
of course i could try the bentinite first then if no worky do liner or well.
