zhkent says " When the pond fills, the porus soils that are in the basin area of the pond would fill with water also, possibly very slowly.
I think this happens at some pond sites.
I would not think of this as a leak, since the water cannot escape through the sides, bottom, or past the dam."
I agree with this comment, but how long would you estimate the soaking process to take? I realize it depends a lot on the thickness of porus soils in the basin. HOwever the soaking process should not take much longer than a month or two should it?
