The Lake Issyk Tragedy: How a Mountain Mudslide Destroyed a Kazakh Resort (9 photos)

Mountain lakes are strikingly beautiful and always draw crowds of tourists. But that beauty can be deceiving, and at any moment, a picturesque body of water can turn into a deadly trap. That is precisely what happened to Lake Issyk in Kazakhstan—a favorite retreat for residents of Alma-Ata (now Almaty) and visitors alike during the Soviet era.





Lake Issyk is one of the jewels of the Trans-Ili Alatau range, nestled in a basin framed by rugged peaks 1,760 meters above sea level. Crystal-clear water, stunning vistas, and crisp mountain air have drawn visitors for generations. The first vacationers arrived at its shores before the Russian Revolution, back when Alma-Ata was still known as Verny.



Under the Soviet Union, Lake Issyk was transformed into a well-equipped resort area. A highway was built connecting it to the republic's capital, with buses running every half hour. It was popular not just with ordinary citizens, but also with high-ranking officials and foreign dignitaries, including Nikita Khrushchev and Vietnamese leader Ho Chi Minh.





VIP Visitors

On July 7, 1963, another high-level delegation arrived at the lake. The guests included Alexei Kosygin, First Deputy Chairman of the USSR Council of Ministers, accompanied by Kazakh leader Dinmukhamed Kunaev. Valentina Tereshkova, the first woman in space, was also scheduled to join them, but cancelled her trip at the last minute.

Dinmukhamed Kunaev provided a firsthand account of the events that unfolded that day at Lake Issyk. In his memoir,

From Stalin to Gorbachev

, he wrote:

“The day was clear, the scenery indescribably beautiful. Kosygin was mesmerized by the lake and nature… Then I noticed something wrong: a brown torrent was rushing down from the mountains. There was no doubt—it was a sight I knew all too well. A mudslide! The surge plunged into the lake. The water turned murky and seemed to boil. The impact triggered a massive wave, flipping over vacationers' boats. The mudslide hit the pier; I saw a man standing on it thrown into the air… ‘Before the river bridge is washed out,’ I said, ‘we need to leave!’ Kosygin didn't budge. He seemed spellbound by what was happening. I told him every second counted—and that we had to organize immediate rescue efforts…”



The Soviet leaders escaped the disaster area at the very last moment. Behind them, the bridge connecting the lake to the safety of the main road collapsed. That day, the mudflow swept down nearly six million cubic meters of rock, water, and debris. Ivan Aushev, director of the Issyk resort complex where the dignitaries were staying, later admitted that if Kosygin had not been visiting, the death toll would have been significantly lower.



Because of the VIP visit, the entire right side of the lake—the most developed area—was cordoned off. Ordinary vacationers were forced to crowd along the river feeding into the lake. It was precisely where the destructive wall of mud and debris barreled through.



The Aftermath

Forming high in the mountains, the mudslide gained overwhelming momentum as it swallowed boulders and uprooted trees. It first struck Lake Issyk, destroying the landmark entirely. The picturesque lake was reduced to a muddy puddle littered with massive rocks and splintered trunks. But the destruction didn't end there. The torrent continued down to the town of Issyk, destroying 200 homes, damaging the local hydroelectric station, and flooding the cellars of the Issyk Winery.



In the Soviet era, revealing the true scale of disasters was forbidden, making the exact death toll impossible to verify to this day. Official and historical sources estimate between 52 and 100 fatalities, but eyewitnesses believe the actual number of victims was far higher.



Lake Issyk remained in ruins for nearly two decades. Restoration work finally began in 1983—a massive undertaking that was only completed in the early 1990s, after the collapse of the USSR. Despite these efforts, the present-day lake bears little resemblance to its former self, having shrunk in both surface area and depth. The resort infrastructure was never fully rebuilt either. Even so, Lake Issyk continues to captivate visitors with its beauty, drawing thousands of tourists every year.
