First Test Of Boulder Dam Spillways

The video tutorial discusses the Boulder Dam, focusing on its spillway, which prevents water overflow by discharging 15,000 cubic feet per second. It highlights the dam's capacity to store 10.5 trillion gallons of water and its power output, which is four times that of Niagara Falls. The tutorial emphasizes the role of human intervention in controlling water flow to prevent potential floodwaters, showcasing Boulder Dam as a significant achievement in harnessing nature.
