I live in the Sandhills of NC, Pond size 150ft by 90ft by 6ft deep lined with gumbo clay, compacted with a vibratory roller/compactor, clay depth 8 to 12inches thick, using well to pump water in, tool 4 days to fill, left pump on for a week and shut it off, lost about 6 inches in the 1st 24hrs. How long for the pond to seal with only losing water to evaporation? Do I need to leave the pump running for a few months? Any information would be greatly appreciated.
