I have two ponds on my property and both are leaking. They are each about 100' x 60' and 5' deep. I've read about using bentonite, but most of the things I see say that the correct application is to drain the pond, till it, and apply the bentonite. Drain and till isn't an option. I've been thinking about buying some bentonite at the Co-Op and just throwing it in the pond. Is that just a waste of money and time? The other "neighborly" idea I've gotten is to get some hogs. That isn't happening either.
Would appreciate any idea from you guys.
