Besides seeing wet spots around the downstream side of a dam, is there any other indicators where a leak might be? Or, are there any ideas on how to find a leak? By the way, I'm not seeing any wet spots around the dam side.

I have a small (maybe 1/8 acre) pond that has been about half (4 foot) full but it empties to about 2-3 feet deep after heavy rains. It takes several weeks to drain down. Any help is greatly appreciated.

I'm located in sw Pa.
