Mark-Brettski brings up a very good point. You should keep very accurate records of your rainfall, pond water level and evaporation amounts in your area. I know it would be hard to wait another year but they say the first couple of years that water seeps into newly covered ground. With time and records you could see if the leak or seep is slowing down. In the meantime you could stock some fathead minnows and a few BG to start your forage base.
