So the ground table is just starting to fill up and water is just starting to enter the pond.
The water is percolating out of the ground at 24" below full pool, i'm currently down 36" All of a sudden I had an A-HA moment "That's where the leak is" I said to myself.....when the groundwater level drops the water flows right back in, that explains everything

So the question is where do i fix it and whats the best method

My idea is to trench down just above high point water level and pack the trench with clay
im almost positive this is the last problem I want to make sure I do it right
any ideas?
