DC70, thanks so much for this, very helpful! I just have two questions.
1) Why sock pipe? It's perforated, right? If so, it seems like it water would seep out of the sock pipe and into the dam over time? Could you just use PVC pipe instead of sock pipe?
2) What happens in a very heavy rain when the water level gets above the highest part of the sock pipe (circled in attached picutre)? Seems like the water would spill out into the dam at that point?
