An old farmer with some ponds said to caulk a leak in a pond by putting in large amounts of "newspaper" to find the leak and plug it. I've never read this here and I might assume his pond sealed itself, but you just never know -- sometimes the oldtimers know things I could never imagine.

I have a leak that I believe is coming through a rock ledge and finding it's way to the bottom backside toe of the dam at about 2 gallons a minute. Have a spring feeding the pond so it does not drop until July -- Sept, and the leak has not gotten worse. Have a very large watershed - so at the first good rain this 2 acre pond fills again.

Newspapers -- is that crazy? I throw away a bunch of them and well, I'm grasping at straws and have no more money to dump into this pond.
