This man is helping the community! Animals can safely cross over the small rivers he does this on and it won't overflow! truly a job well done.It's the hydraulic jump and the dogs walking across that made it for me. Well done.Three of him and you got yourself a great pyramid in 1 year. Tops. Unbelievable skill, workmanship and most of all stamina.Incredible skill and workmanship .Every dam is different and truly works of art.
