Building these diversion tunnels required blasting into each side of the canyon to create 17 meter tall tubes.

要建造这些引水道，会需要炸入峡谷的两侧，创造出十七公尺高的管道。

On February 1st, the diversion tunnels opened to fill the dam's reservoir, capable of holding twice the Colorado River's annual flow.

二月一日，引水道开启，让水坝的水库装满水，蓄水量是科罗拉多河年流量的两倍。
