One problem I have in this situation is that the sediment pond full pool level is only about 9 inches above the main pond full pool level. Then the tiny pre-sediment pond ahead of it that I dug last fall is only a few inches above the sediment pond and it at full pool is right at the bottom of a culvert that is at the exact top of the hill (culvert brings water in from a farm field terrace and the culvert is there because a farm road passes over it).
So I was working with really tight elevation differences. Had my pond full pool level not been so close to the top of the hill where this terrace water runs in, I could have done things differently and probably a lot better. But I think it works pretty well as is, compared to having nothing like I had before I built it.
