The nrcs in our area generally just makes sure that the pipe extends out from the toe of the dam about 8 to 10 ft enough so that the outflow want cut into the dam. My 30 inch pipe has cut a huge hole but this happened the first time it had a full discharge. Once the hole is cut it generally stays full of water and no longer cuts any further because the out flow simply hits a pool of water when it discharges. Then it flows out of the pool and down the natural stream that existed prior to the pond.
