Posted a while back about my pond leaking water pretty badly. Now that it has dried out a bit it seems pretty obvious my pond water is seeping into the ditch behind my pond which is about 40 foot away. The leak appears to be pretty bad, I can actually see it flowing in a little stream in a couple of spots. Plus the ditch stays wet from my house on down. Any ideas on a fix for this kind of issue.

Another observation, something is wallowing out and making holes under the water line around my bank, even bored a hole behind my dock all the way across. I thought it was nutria but have not seen any evidence of their little torpedo's. Can catfish do this too.
