It's the hydraulic jump and the dogs walking across that made it for me. Well done.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.Have to say, the cement mix didn’t look dry when he capped the pipes. I’m not sure I would give it a long life.An interesting project, it looked really good but I could see leakage around the sides of the dam, maybe next time you can go further into the bank and a thicker main wall as I can forsee that collapsing within weeks.
