Great feedback from the others. I would suggest reading THIS THREAD regarding another forum member's recent issue with a short pipe through the dam. You will want to extend it down the backside to below the toe of the dam, in order to prevent erosion of the backside of the dam.

But then what diameter pipe is needed? I recommend visiting the county NRCS office to see if they will run a calculation for you.
