My pond is kind of a hybrid. It is mostly dug, but the land is sloping, so there is kind of a dam in the downhill side. The location has seasonal surface and groundwater flow. One of the reasons I got started with digging it was because the field in that location was always too wet to mow. My tractor was sinking in up to its axles. I knew it was groundwater coming up to the surface because it was puddling there even when we didn't have rain for weeks. So that's where we started digging.
We were all set to have a culvert going through the dam, for overflow. Then I had a fellow from NRCS come out to look at it just after we broke ground. He turned us away from the culvert idea and onto the spillway. I do not recall him mentioning another system in addition to the spillway. I'm not even sure what I could be, or where.
