Lake Tana is important because of the monasteries but more so because the Abbay or Nile flows right through it.

塔纳湖的重要性来自修道院，更因为尼罗河流经此地。

These streams became known as the blue Nile and the White Nile, and by 1618, Spanish missionaries had finally discovered the source of the blue Nile down at lake tana in the highlands of Ethiopia.

这些溪流被称为蓝尼罗河和白尼罗河，到 1618 年，西班牙传教士终于在埃塞俄比亚高地的塔纳湖发现了蓝尼罗河的源头。

Which often causes Lake Tana in the northwest corner of Ethiopia to overflow and spill water into the Blue Nile that runs out of it sending a flood surge downriver clear through across Egypt and into the Mediterranean.

这常常导致埃塞俄比亚西北角的塔纳湖泛滥，从塔纳湖流出的湖水溢入青尼罗河，洪峰顺流而下，穿过埃及，直达地中海。
