The Arpa rises on the southern flank of the Sangesurkamm in the Armenian province of Vajoz Dzor . It initially flows south. South of Jermuk , the Arpa is dammed up to form the Ketchut reservoir . Later she turns west. It flows 2 km south of the capital of the province, Yeghegnadsor . The river turns south again in the lower reaches and crosses the border to Nakhichevan. Eventually the river reaches the macaws streaming to the southeast.
