According to the Central Maluku legend, the three rivers:
Eti River,
Tala River and Sapalewa River, flow from a
sacred lake on the mountain peak called "Nunusaku". There grows a
ficus tree with three big roots, each stretching in the direction of the abovementioned rivers, and this is the origin of the native people of the island of Seram, the so-called "Alifuru" people, who later inhabited the surrounding islands. The three rivers are known in local language as
Kwele Batai Telu or
Kwalai Batai Telu ("three stream branches"; Indonesian: "Tiga Ruas Sungai") watering the island of Seram (
Nusa Ina). "Nunusaku" (which was a lost great kingdom according to legends) Alune and Wemale people live in the watershed areas of the three rivers: Alune people inhabit the whole area of Eti river, mountainous area of Tala river and most of the coastal area of Sapalewa river, whereas Wemale people occupy the area east of Tala and Sapalewa rivers. ==Hydrology==
