Just wondering how long (on average) it takes a new pond to seal and hold water. I just had one finished (1/2 acre +/-) a few weeks ago with a couple of good (3" total) rains and it keeps SLOWLY going down. I'd say I'm losing about 1/2" a day. It will fill a 6" to a foot and then over a week will slowly come down. Seems like it will NEVER fill!

Should I be concerned? The "digger" says to give it some time, a lot of dirt was disturbed and it needs to "settle down".

Do you agree?
