Meadowlark,
I too had a dam leaking on a pond I had built last Aug. It was very dry after it was dug and it cracked the clay core. It didn't finish filling until Feb. Since the frost was still in the ground I had no idea it was leaking until the spring thaw. It was 1/2 full in Oct. and I went ahead and stocked it, so there was no way I was going to drain to fix. My excavator said he would repair for free if I could come up with a way to do it on my terms. I read this post and figured what the heck. He cut about 1/2 way thru the dam and repacked at the leaks back in June. Hadn't had any real rain since and between the leak and lack of rain the pond was down almost 5'. Well the rains have finally came ( 9 1/2" in 8 days ) and filled the pond within a foot of full with no signs of leaks. It worked for me too.....THANKS!
