There is a Dam very near me. This Dam had a leak discovered in it a year after completion. So this leak has been there for over 50 years. It has been minitored and even tried to be repaired once. The size of the leak has not changed at all. I guess what I am saying here, is that these leaks just did not happen all-of-the-sudden. What I was told is this. After the Levys failed during Katrina and there was a catastrophic loss, all things pertaining to fllod control and the such were re-evaluated. This may be why there are so many Dams in the state in the same draw down condition. Remember years back when that bridge failed in another state and it was full of cars? I drive a pretty good distance to work everyday, and I see PA replacing and or fixing bridges in numbers like I have not seen before.

Just my 2 cents
