It is no longer the highest or tallest dam, but it is still one of the tallest.

它不再是最高或最高的水坝，但它仍然是最高的水坝之一。

So workers had to build the 726 foot high dam five feet at a time, using individual buckets of concrete that sped down to them on cables every 78 seconds.

因此，工人们不得不一次建造 726 英尺高的 5 英尺大坝，使用单独的桶每 78 秒在电缆上加速流向他们的混凝土桶。
