Lake Arpi is located in the Shirak Province of Armenia, on the Ashotsk plateau in the northwestern part of the country. The lake sits at an altitude of 2,025 m with an area of 20 km2. It originates from a volcano tectonic earthquake.

In 1951, the Arpi dam was built to create the Lake Arpi reservoir and artificially increased the natural state of 4.5 km2, 1.6 m deep, and volume of 5 million cubic meters. The reservoir's dam is 10 m high and 80 m long. The reservoir-lake spans 7.3 km long and 4.3 km wide, with an area of 20 km2, 8 m deep, and a volume of 30 million cubic meters.Lake Arpi has become the second most important body of water in Armenia, next to Lake Sevan. It is used for irrigation and hydropower production. The lake is fed by meltwater and four streams, and it is the source of the Akhurian River.
