North Aral Sea

A big lake is growing back.

It is called the North Aral Sea. A river feeds it. Long ago, the water went away. People used the river for farms. This made the lake split in two.

Now, people want to save the lake. They built a strong wall to hold water.

The water is rising fast. The water is also less salty. This helps many fish live there. People can go fishing again. It is good to see the water return.

The North Aral Sea is a large lake.

It is fed by the Syr Darya River. Long ago, the Aral Sea was much bigger. In the 1960s, people moved water from the rivers. They used the water for crops like cotton. This caused the sea to shrink. Between 1987 and 1988, the sea split in two. The North Aral Sea stayed in the north.

Kazakhstan wants to save this lake. In 2005, they built the Kokaral dam. A dam is a strong wall built across water. This dam helps hold the water in the lake. Since then, the water level has risen fast. The water is also less salty now. This change helps fish live in the lake.

Some people even put mackerel fish in the river delta. This helps people go fishing again. People may build a second dam in the future. This could help the water rise even more.

There are also plans to help other parts of the sea. These plans aim to stop water from being lost in the desert.

The North Aral Sea is a very important part of a much larger body of water. It is a lake located in Kazakhstan. This lake is fed by the Syr Darya River. Long ago, the Aral Sea was one huge sea. It began to shrink during the 1960s. This happened because the Soviet Union moved water from two rivers. They used the Amu Darya and the Syr Darya rivers for farming. They wanted to grow food crops and cotton in Kazakhstan and Uzbekistan.

As the water left the rivers, the sea began to disappear. The water levels dropped very quickly. This caused the sea to split into two separate parts. This split happened between 1987 and 1988. The northern part became the North Aral Sea. The other part became the South Aral Sea. Because the water was being moved for crops, the sea could not stay full. This change turned parts of the old sea into a sandy desert.

People have worked hard to help the North Aral Sea recover. The government of Kazakhstan decided to restore this northern lake. They used a structure called the Kokaral dike to help. A dike is a strong wall used to hold water in. The first dike was not built well and failed two times. However, the government funded a much stronger design in 2005. This new dam worked very well for the lake.

Since the new dam was finished, the lake has changed a lot. The water levels have risen faster than anyone expected. By 2008, the water level was much higher than it was in 2003. The water is also less salty now. This is good because many fish need less salt to live. Fish stocks have increased in the area. People have even introduced mackerel fish to the Syr Darya river delta. They tried to add tuna in 2009, but that did not work.

There are many new ideas to help the water even more. Some people want to raise the Kokaral dike by several meters. This might bring the lake back to how it was before 1970. Other plans include building a second dam further north. This could help the city of Aralsk have more space for boats. There are also ideas to build channels to move water to other areas. These paths would stop water from being lost in the desert.

The North Aral Sea is a vital body of water located in Kazakhstan. It is a specific portion of what was once the massive Aral Sea. This northern section is primarily fed by the Syr Darya River. The health of this lake is important for the local environment and people. It serves as a major site for fishing and ecosystem recovery. Understanding its history helps us see how human choices change the Earth.

The history of this sea began with a major change in water use. During the 1960s, the Soviet Union diverted two major rivers. These rivers were the Amu Darya and the Syr Darya. The goal was to irrigate crops like cotton and food plants. This water was moved to fields in Kazakhstan and Uzbekistan. Because the rivers no longer reached the sea, the water levels dropped. This process caused the once-vast Aral Sea to shrink rapidly.

As the water levels continued to fall, the sea underwent a physical split. This division occurred between 1987 and 1988. The water levels became so low that the sea separated into two distinct parts. The northern portion became the North Aral Sea. The remaining southern portion became the South Aral Sea. This split changed the geography of the entire region forever. Many areas that were once underwater turned into a sandy desert.

After the fall of the Soviet Union, Kazakhstan took steps to help. The government decided to restore the northern lake using the Syr Darya. To do this, they used a structure called the Kokaral dike. A dike is a long wall built to hold water in one place. The first attempts to build this dike were not successful. The poorly built structure failed two different times. However, the government funded a much more robust design in 2005.

The 2005 dam project led to very successful results for the ecosystem. Since the new dike was completed, water levels have risen faster than expected. By 2008, the water level had increased significantly compared to its 2003 level. This rise in water also caused the salinity to drop. Salinity is the measure of how much salt is in the water. Lower salt levels are better for many types of aquatic life. Because of this, fish stocks have increased in the area.

New species have even begun to inhabit the recovering waters. Mackerel were introduced at the Syr Darya river delta to support fishing. While people tried to introduce tuna in 2009, that specific attempt failed. Despite this, the increase in fish makes local fishing viable again. Scientists and leaders continue to look for ways to protect this progress. They want to ensure the water stays in the lake rather than disappearing.

Future plans exist to expand the recovery of the North Aral Sea. One idea is to heighten the existing Kokaral dike by several meters. This could potentially restore the lake to its level from before 1970. Another plan involves building a second dam further north. This would be located halfway between the dike and the city of Aralsk. Such a move could help the city regain its maritime space. There are also ideas for new channels to move water to other areas. These channels would prevent water from being lost to the desert.

Beyond the water itself, the region holds ancient history. Near the village of Akespe, researchers found a very large site. In 1925, many fossils from the Oligocene period were discovered there. These fossils were found near the northern shore of the Aral Sea. This shows that the area has been a place of life for millions of years. Today, the effort to save the North Aral Sea connects ancient history with modern science. It is a continuous story of how water and life interact.
