Sarez Lake is a striking high-altitude body of water in the Pamir Mountains of Tajikistan, formed by a natural dam triggered by a massive earthquake in 1911. The earthquake caused a huge landslide that blocked the Murghab River, thus creating the lake. Over time, the lake's depth has increased, and currently, it spans about 75.5 kilometers. The Usoi Dam, which holds the lake's waters, is considered the highest natural dam in the world. Sarez Lake is located in a remote and seismically active region, making it difficult to access and posing significant risks in the event of a dam breach due to a potential natural disaster. The area surrounding the lake is not heavily populated, which has allowed its environment to remain relatively untouched, offering stunning natural beauty and unique biodiversity. It lies within Tajik National Park, a UNESCO World Heritage Site. The serene turquoise waters of the lake contrast with the rugged, reddish hues of the surrounding mountains, providing an extraordinary visual spectacle. The site is of significant interest to geologists, environmentalists, and adventure tourists.
