Jim - I just finished a pond and nearly made the same mistake. After digging at least 8 feet down into the clay the crew broke through into "sugar sand" and water springs started seeping into the pond. Pond Boss experts highly recommended that it be sealed before any more water got in there. The crew pumped the water out and put 2 tons of Betonite clay into the soil and then put a couple feet of clay over the top. Now we are waiting on the rain to fill the pond.
