Lake Balkhash

Lake Balkhash is a very large lake.

It sits in the land of Kazakhstan.

The lake has two different sides. One side has fresh water. The other side is salty.

A long piece of land sits in the middle. This land splits the lake in two.

Rivers flow from mountains into the lake. This helps the lake stay full.

People live near the water. They go fishing to find food.

It is a very special place.

Lake Balkhash is a very large lake in Kazakhstan.

It sits in Central Asia. It is the 15th largest lake in the world.

The lake has two very different sides. A long piece of land called the Saryesik Peninsula sits in the middle.

This land splits the lake into two parts. The western side has fresh water. It is shallow and quiet. The eastern side is much deeper. It is also salty.

Many rivers flow into the lake. The Ili River is the most important one. It brings water from the mountains in China. The lake also gets water from the Karatal River.

People live near the shores. The city of Balkhash is the largest town nearby. People there do fishing and mining.

However, the lake is shrinking. This happens because people take water from the rivers. The lake is also changing due to the weather. This is a big concern for the area.

Lake Balkhash is a huge body of water in southeastern Kazakhstan.

It sits in the eastern part of Central Asia. This lake is very important because it is one of the largest in Asia. In fact, it is the 15th largest lake in the whole world. It rests inside a large, closed area called the Balkhash-Alakol Basin. This basin is a low area surrounded by mountains.

Because the basin is closed, no rivers flow out of the lake. All the water that enters stays there.

Many rivers bring water to the lake from different places. The Ili River is the most important one. It brings about 73 to 80 percent of the water. This river starts in the mountains of the Xinjiang region in China. Most of its water comes from melting snow in the spring.

Other rivers like the Karatal and Aksu also flow into the lake. The Karatal is the second largest source of water. The lake also gets some water from deep underground. This constant flow of rivers keeps the lake filled.

The lake is actually two different lakes joined together. A long piece of land called the Saryesik Peninsula sits in the middle.

This peninsula divides the water into a western and eastern half. They are connected by a narrow path called the Uzynaral Strait. The western side is shallow and filled with fresh water. It covers about 58 percent of the surface area. The eastern side is much deeper and much saltier. The water there can look bluish or even emerald-blue.

History tells us that this area has changed many times. The name Balkhash comes from old words meaning "tussocks in a swamp." Long ago, the area was home to nomadic Turks and Mongols. They mixed their cultures with people who lived in settled towns. In the year 1864, the area became part of the Russian Empire. Later, after the Soviet Union ended in 1991, it became part of Kazakhstan. The lake has always been a vital place for the people living nearby.

Today, people use the lake for many different jobs. The city of Balkhash is the largest town on the shore. It has about 66,000 people living there. Many people work in fishing or mining.

You can even see large mining plants near the water.

However, the lake is currently shrinking. This happens because water is taken from the rivers for industry and farms. Changing weather and dry climates also make the lake smaller. This is a big concern for the future of the lake.

Lake Balkhash is a massive body of water located in southeastern Kazakhstan.

It is situated in the eastern part of Central Asia within the Balkhash-Alakol Basin. This basin is an endorheic basin, which means it is a closed system. In such a system, water flows into the basin but does not flow out to any ocean. This makes the lake one of the largest in Asia and the 15th largest in the world. The lake sits in the deepest part of a vast depression. This depression formed as a sloping trough between mountains and an older geological block.

The lake is unique because it is split into two distinct sections. The Saryesik Peninsula, which means "Yellow Door" in Kazakh, divides the water.

These two parts are connected by the Uzynaral Strait. The strait is 3.5 kilometers wide and about 6 meters deep. The western half is relatively shallow and contains fresh water. It covers 58% of the total surface area but only 46% of the total volume. The eastern half is much deeper and contains saline, or salty, water. The average depth of the eastern basin is 16 meters, while the maximum depth reaches 26 meters. The water in the west has a yellow-gray tint, while the east can look bluish or emerald-blue.

Water enters the lake through several different river systems. The Ili River is the most significant source. It provides between 73% and 80% of the total inflow. The Ili River begins in the mountains of China's Xinjiang region. Its flow is largely driven by vernal snowmelt, which is snow that melts in the spring.

The Karatal River is the second-largest source of water. Other rivers, such as the Aksu and Lepsy, also contribute to the lake. The lake also receives some water from underground sources. However, the lake is losing water through evaporation and human use. In the year 2000, total inflow was 22.51 cubic kilometers per year. Total losses, mostly from evaporation, reached 24.58 cubic kilometers per year.

Historically, the region around Lake Balkhash has seen many different cultures. The name "Balkhash" comes from Tatar, Kazakh, and Southern Altai words meaning "tussocks in a swamp." As early as 103 BC, Chinese records referred to the area as the Bugu, Buku, or Busu polity. From the 8th century, the land south of the lake was known as Jetisu, or "Seven Rivers." This was a place where nomadic Turks and Mongols met settled peoples. In 1759, the lake marked the northwestern limit of Qing suzerainty. Later, the Treaty of Tarbagatai in 1864 ceded the area to the Russian Empire. Following the dissolution of the Soviet Union in 1991, the lake became part of Kazakhstan.

The lake's size has changed significantly over time. In 1910, the lake's area was estimated at 23,464 square kilometers. By 1946, the area had shrunk by nearly one third to 15,730 square kilometers. Much of this shrinking is due to the diversion of water for human needs. For example, the Kapshagay Hydroelectric Power Plant was built on the Ili River in 1970. The reservoir used by this plant changed the balance of water reaching the lake. Between 1970 and 1987, the water level fell by 2.2 meters. There is also concern that climate change and desertification will affect the lake further. These factors can lead to a loss of water and changes in the local ecosystem.

People living near the lake rely on it for their livelihoods. The city of Balkhash is the largest shore city, with about 66,000 inhabitants.

Local economic activities include fishing, mining, and ore processing. The landscape around the lake is varied. The western and northern shores are high and rocky, made of granite, schist, and limestone. The southern shores are low and sandy, often containing many water pools. You can also see industrial sites near the water.

The lake contains 43 islands, including the large Tasaral and Basaral islands. As water levels lower, new islands can actually form.

The climate at Lake Balkhash is continental, which means it has large temperature changes. The average mean temperature is about 24 degrees Celsius, but January averages -14 degrees Celsius. The area is quite dry, with only 131mm of precipitation per year. This dryness causes a high evaporation rate. The lake freezes every year from November until early April. The wind can be strong, creating waves up to 3.5 meters high. These winds also create steady clockwise currents in the western part of the lake. Understanding these complex systems helps scientists study how large lakes respond to environmental changes.
