Nenglos

Nenglos (S. "Snow-water", Os. "Nenloss") was the main river of Harvaneth, the southern region of Siragale and centre of Siranwaith settlement in the mid-Third Age. Its tributary the Nimeithel (S. White-well) ran from the White Downs of the Shire near Harbottle. Originally the banks of the Nenglos were surrounded by trees, but they were reduced to scattered copses by the depredations of Men.
