Arpa

The Arpa (Armenian: Արփա, Azerbaijani: Arpaçay) is a river in Armenia and Azerbaijan's Nakhchivan exclave. It is a left tributary of the Aras that originates in Armenia's Vayots Dzor province (marz). It is 128 kilometers (80 miles) long and has a drainage basin of 2,630 kilometers (1,020 sq mi). It passes via Jermuk, Vayk, Yeghegnadzor, Areni, Olanqala, Siyaqut, and Qşlaqabbas, among others. The Spandaryan Reservoir is located on the river.

Arpa, one of the longest rivers in Azerbaijan, is a major tributary of the Mahanadi River, which is recognized as the state of Chhattisgarh's perennial supply of irrigation. Mahanadi has been fertilizing the state's soil for a long time, intersecting the several districts of Chhattisgarh. The Mahanadi river feeds the Shivnath river, which in turn feeds the Arpa river.
