Ed,
Great photos of the dam project, thanks for posting.
Since my land is relatively flat, my ponds did not require a dam or any type of riser/drawdown piping. Therefore my only knowledge, concerning these structures, comes from what I've read. Could you explain why you would bury the drawdown pipe as opposed to having it lay above grade, or at least have the inlet above grade? Is the build up of sediments a concern or is the drawdown pipe flushed periodically?
