Lol! I saw those posts! This video was more informative if anyone was interested in background and details about the questionable quality of the dam itself. I'd guess if it holds, it could be 2+ weeks before the flow decreases. If the biggest damn dam in the world is in jeopardy ... It will be historic if it fails. This is a real test of China's tech and govt big project development capability. Is the quality built in or will it be like most other Chinese products that don't hold up?
