The dozer guy has done several ponds and dirt work not sure of a number though. I think you are on to something with the dirt mover though. He did survey and everything several times but not sure how it could've gotten that far off. So, no the spillway never worked and the finger basically back filled. Unfortunately I do not live at the same place as the pond- so earlier in the week it was full in the above pics, then today bam...
