Welcome, colonel! Glad to have on the forum!

Keep an eye on it, but losses measured in inches do seem to be the norm for new ponds as it takes awhile for water to wick into the surrounding soils. Just watch carefully to ensure that it doesn't suddenly get worse.

Post a pic - newly filled ponds deserve some publicity!

thanks!Ill keep watching it see what it does in the next week.ill try to get a pic on it.
