hello, I rented a excavator and added on about 100 feet to my 1/4 acre pond. Most of it basically a dam. I finished just in time cause we got a good rain for the first time in 2 months. The pond kinda goes on a slant so the enitre pond filled up overnight. I noticed earlier that it lost about 6 inches today and I looked around and their was a wet spot at the bottom of the dam where it meets the ground. I dug around and there are seepage areas for about 5 feet length along the bottom. I went into the pond and tried packing in from the inside, don't know if it will help. I'm just wondering if anyone would be able to tell me what I can do to limit it or stop it. Is it possible it will seal itself since it's so newly dug out? please help!
