Goṇa untranslated

Goṇa (Goṇaka). A river to the south of Anurādhapura. On its banks, King Cūḷābhaya built the Cūḷa Gallakavihāra (Mhv.xxxv.13), and Vaṅkanāsikatissa, the Mahā Maṅgalavihāra (Mhv.v.113). Once, when Dhātusena was fleeing from his enemies with a Thera, his uncle, the river was found to be in flood, but a Nāga king took them across (Cv.xxxviii.24). Later, when building the Kālavāpi, Dhātusena dammed up the river. Cv.v.42.

It is identified with the modern Kalā-oya (Cv.Trs.i.30, n.3).3.
