Lake Sevan is the largest body of water in Armenia.

It is located in the Gegharkunik Province within the Caucasus region. This massive freshwater lake is also one of the largest Alpine lakes in Eurasia. Many people call it the "jewel" of Armenia. The country recognizes it as a national treasure. It is a vital ecosystem for the environment and the people.

The lake functions through a complex water cycle. It is fed by 28 different rivers and streams. However, most of this incoming water does not stay in the lake. About 90% of the water evaporates into the atmosphere. Only about 10% of the incoming water is drained away by the Hrazdan River. This balance is essential for maintaining the lake's volume and depth.

Historically, the lake has had many different names. In classical antiquity, it was known as Lychnitis. During the 17th century, explorer John Chardin called it the "Lake of Erivan." He noted that Persians called it "Deria-Shirin," meaning "sweet lake." Turkic names like Gokcha, meaning "blue lake," were also used. Some scholars believe the name Sevan comes from the Urartian word "suinia," which means "lake."

During the Soviet period, humans changed the lake significantly. In the 1930s, authorities began using the water for industrial goals. They wanted to provide irrigation for the Ararat plain. They also wanted to generate hydroelectric power. Engineers deepened the Hrazdan riverbed and bored a tunnel under the lake. This allowed water to flow out more easily. Consequently, the water level dropped by about 19 meters. The volume of the water also decreased by more than 40%. This caused the water quality to drop and destroyed natural habitats.

To stop this decline, leaders decided to divert new water into the lake. They planned to build large tunnels to bring water from highland rivers. The first project was the Arpa-Sevan tunnel. This tunnel was completed in 1981. It brings up to 300 cubic meters of water to Sevan every year. Later, the Vorotan-Arpa tunnel was built. It was inaugurated on April 26, 2004. This tunnel brings an additional 180 cubic meters of water to the lake annually.

These engineering projects have helped the lake recover. Since the mid-2000s, the water level has been rising significantly. In 2007, reports showed the level rose by 2 meters in six years. The water level reached 1900.44 meters in November 2019. The government forecasts that the level will continue to rise. However, climate change might affect this. It is estimated that the outflow of the Arpa River could decrease by 22% by 2030.

Lake Sevan is vital to the Armenian economy today. It provides about 90% of the fish in Armenia. It also provides 80% of the country's crayfish catch. The lake is a major center for tourism and recreation. It has the only beaches in Armenia. People visit to swim, sunbathe, and participate in sports like windsurfing or sailing.

Cultural sites around the lake attract many visitors. The Sevanavank monastery sits on a peninsula. This area was a major island until the mid-20th century. There are also other important sites like the Hayravank monastery. In the village of Noratus, there is a field of khachkars, which are stone crosses. The lake remains a central part of Armenian life, culture, and history.
