FishnChips: I don't know about compacting soil around pipe either. Was hoping someone could opine on doing it with a dozer vs a track hoe vs getting a manual compactor and doing it by hand or some other option when we put pipe back in.
Thanks for the suggestion Esshup. There's an NRCS office in Bedford. I'll hit them up.
Gus:
1. There is an emerg spillway on the far side.
2. Pipe wasn't horizontal. It sloped from the wet side full pool level down to base of the dam on the back. There were no collars. Collars mandatory for such an install? It was simply a run of 5 connected straight pipes with minor bend at joints.
3. Couldn't tell you what spec pipe. Here's when it arrived.
4. The house is beyond the dam. It's well protected by earth/bedrock contours that would push water away. Guessing its 8' above the wide pasture below/inline with the dam you see the vehicles parked in. There's a drainage not in that shot that handles the normal flow. Old timers say that pasture has had water flowing in it a couple times.
This shot from up behind the house may give a different perspective. You can also see the dam dipping down a bit better in the green circle. The dam is mostly behind the trees on the right, but the view may be helpful.
