Kazakhstan Prepares for Flood Season by Releasing Water from Reservoirs

Kazakhstan's Ministry of Water Resources and Irrigation (MWRI) has begun releasing water from key reservoirs across the country to prepare for the influx of meltwater expected during the spring thaw. This proactive measure follows the devastating floods of spring 2024, the worst in 80 years, which affected multiple regions and displaced over 120,000 people. By pre-emptively releasing water from reservoirs, Kazakhstan hopes to mitigate the impact of the spring flood season. This preparation underscores the importance of coordinated water management to protect communities, agriculture, and infrastructure from the devastating effects of extreme weather events. In early January, the MWRI held a meeting to discuss water management strategies for the upcoming flood season. Authorities have initiated controlled releases in reservoirs located in the west, east, north, and center of the country - regions hit hardest by last year’s flooding. These releases are designed to reduce water levels in preparation for spring meltwater. Astana Reservoir: Between December 20, 2024, and January 3, 2025, 5.06 million cubic meters of water were released, lowering the reservoir to 83% of its total capacity. By April 1, its volume will be further reduced to 73% (300 million cubic meters). Aktobe Reservoir: Currently holding 51 million cubic meters, this will be lowered to 47.32 million cubic meters by April. Bitik Reservoir (West Kazakhstan): Discharging at 8.3 cubic meters per second, its volume has been reduced to 34.45 million cubic meters. Bukhtarma Reservoir (East Kazakhstan): Now at 79% capacity, this will be reduced by another 8% by spring. Yntymak Reservoir (Karaganda Region): Of its current 69 million cubic meters, only 39 million cubic meters will remain to accommodate floodwaters. Kengir Reservoir (Ulytau Region): Reduced to 86% of capacity, it will be lowered by an additional 11%. Upper Tobolsk Reservoir (Kostanay Region): Holding 585.4 million cubic meters, its volume will be reduced to 61% (499.37 million cubic meters) by April. MWRI head Nurzhan Nurzhigitov emphasized the importance of strategic water management throughout the year. “In spring, it is critical not only to collect floodwaters in reservoirs but also to distribute them to lake systems, natural pastures, and meadows,” he said. Nurzhigitov urged regional authorities to plan for efficient water allocation, noting that during the previous irrigation period, farms received approximately 11 billion cubic meters of water. Efforts to restore and preserve both large and small reservoirs were also highlighted. Last spring’s historic floods inundated regions in northern, western, eastern, and central Kazakhstan for nearly two months. Over 120,000 people were evacuated, with rescue efforts involving multiple government agencies, including the Ministries of Emergency Situations, Defense, and Internal Affairs, as well as local authorities and volunteers. Despite extensive state aid, many citizens raised concerns about the allocation of resources, as previously reported by The Times of Central Asia.

Kazakhstan Receives Abundant Water in 2024

Kazakhstan’s Ministry of Water Resources and Irrigation has reported record water accumulation in the country’s reservoirs and lakes in 2024. This year, Kazakhstan’s reservoirs collected over 75 billion cubic meters of water, including more than 12 billion cubic meters of floodwater from unprecedented spring floods in the western and northern regions. These floods were triggered by rapid snowmelt, leading to significant increases in water availability. According to the Ministry, efficient floodwater distribution helped replenish reservoirs and direct excess water to rivers and lakes that have faced drying trends in recent years. Notable allocations include: Lake Balkhash: Received 15.4 billion cubic meters of water in 2024, a 4-billion-cubic-meter increase from 2023. Of this, 3.3 billion cubic meters came from floodwater. Located 175 miles northwest of Almaty, Balkhash is the largest lake in Kazakhstan and the fifteenth-largest in the world. Caspian Sea: Gained 17 billion cubic meters of water, addressing concerns over its declining water level. The Times of Central Asia previously reported concerns that the Caspian could lose up to 18 meters of water by the end of the century. Kapchagay Reservoir: For the first time in a decade, this reservoir in the Almaty region filled to 100% of its capacity, collecting over 18 billion cubic meters of water. The reservoir regulates the flow of the Ili River, which originates in China and flows into Lake Balkhash. North Aral Sea: Received approximately 2.5 billion cubic meters of water, 400 million cubic meters more than in 2023. This portion of the former Aral Sea is fed by the Syr Darya River and separated from the South Aral Sea in the late 1980s due to water diversion for agriculture. Kamysh-Samar Lakes: Located in the West Kazakhstan region, these lakes were replenished with 80 million cubic meters of floodwater. Minister of Water Resources and Irrigation Nurzhan Nurzhigitov emphasized the Ministry’s efforts to preserve and restore large and small water bodies across Kazakhstan. During the 2024 irrigation season, approximately 11 billion cubic meters of water were supplied to the country’s farms to support agricultural activities. The record water accumulation and successful flood management efforts underscore Kazakhstan’s commitment to sustainable water resource management.

France to Help Kazakhstan Preserve Lake Balkhash

Kazakhstan’s Ministry of Water Resources and Irrigation, the French Development Agency (AFD), and the French Geological Survey (BRGM, Bureau de Recherches Géologiques et Minières) have signed a cooperation agreement to preserve Lake Balkhash. The agreement was formalized on December 4 at the One Water Summit in Saudi Arabia, attended by Kazakhstan President Kassym-Jomart Tokayev and French President Emmanuel Macron. Located 175 miles northwest of Almaty, Kazakhstan’s largest city, Lake Balkhash is the world’s fifteenth-largest lake. Under the agreement, the French side will allocate a grant of 1.35 million €uros to Kazakhstan’s Ministry of Water Resources and Irrigation to develop sustainable water management for the lake. The project includes a comprehensive study of the Lake Balkhash basin to create a long-term preservation plan through 2040. Minister of Water Resources and Irrigation, Nurzhan Nurzhigitov explained, "The trilateral agreement with AFD and BRGM is aimed at studying and sustainably managing water in the Lake Balkhash basin. The document provides for measuring and analyzing the state of water, modeling climate and anthropogenic influences, and forecasting the water balance until 2040. One of the goals of the project is to optimize the operating mode of the Kapchagay Reservoir to stabilize the level of Lake Balkhash. Based on the results of the study, measures will be taken to clean the rivers [feeding Balkhash], prevent soil degradation and water pollution, develop fisheries and ecotourism, and create a regulatory framework for the protection of the lake." At the summit, Kazakhstan’s Special Representative for International Environmental Cooperation, Zulfiya Suleimenova, announced that Kazakhmys Corporation, one of the country’s leading private companies, will contribute $5 million to preserve the ecosystem of Lake Balkhash and adjacent wetlands. In November, The Times of Central Asia reported that 13.5 billion cubic meters of water had been sent to Lake Balkhash via the Ili River from the Kapchagay Reservoir in 2024, raising the lake’s average water level to 341.6 meters above sea level. The Ili River, which originates in China, provides about 70% of Lake Balkhash’s water. Earlier in May, reports indicated that Balkhash’s water level had risen by 23 centimeters since the start of the year, largely due to increased rainfall and snow-melt floods during spring. Additionally, Kazakhstan and China have begun negotiations on the joint management of trans-boundary rivers, including the Ili. As previously reported by The Times of Central Asia, a key focus for Kazakhstan in these talks is to maintain optimal water levels in Lake Balkhash.

Kazakhstan Secures Agreement for 11 Billion Cubic Meters of Water from Neighboring Countries by April 2025

Kazakhstan will receive approximately 11 billion cubic meters of irrigation water from the Syr Darya River by April 2025, following an agreement made by Nurzhan Nurzhigitov, Kazakhstan’s Minister of Water Resources and Irrigation, with representatives from neighboring Central Asian countries. The accord was reached at the 87th meeting of the Interstate Coordination Water Management Commission held last week in Ashgabat, Turkmenistan, and attended by water ministry leaders from Tajikistan, Turkmenistan, and Uzbekistan, with Kyrgyzstan as an observer. This substantial water supply is expected to fill the Shardara reservoir in southern Kazakhstan by April 1, 2025, providing enough water for the region's 2025 irrigation season. Given Kazakhstan’s reliance on irrigation for agriculture, particularly in the arid south, the flow from upstream countries like Tajikistan, Kyrgyzstan, and Uzbekistan is vital. Nurzhigitov noted, "This year, thanks to negotiations and joint actions, we ensured the effective water distribution in the Syrdarya River basin. Agreements on water and energy cooperation with Kyrgyzstan were implemented, and measures were taken to coordinate the operating mode of the Bakhri-Tojik reservoir [in Tajikistan] during this year’s irrigation season.”

Uzbekistan Aims to Develop Agriculture with Smarter Water and Energy Use

Uzbekistan's President Shavkat Mirziyoyev recently held a meeting on the efficient use of water and energy in agriculture. More than 1,600 pumping stations currently use 6.8 billion kilowatts of electricity to irrigate 2.5 million hectares. Through the partnership, electricity consumption can be reduced by 20% by upgrading pumps and solar panels. For example, 92 farmers installed modern pumps in the Khorezm region, saving 20% of electricity. Some sold excess solar energy to the state and received an additional monthly income of 7-8 million UZS ($548-626). Water-saving technologies have helped Uzbekistan save 2 billion cubic meters of water in an area of more than 2 million hectares, and more than 50 local companies are producing these devices. However, some drip irrigation systems are still not working, and the 10 billion UZS ($780,000) subsidy allocated for laser leveling in Karakalpakstan hasn’t been used. Khorezm was also instructed to extend the subsidy for laser leveling to 1 million UZS ($78.00) per hectare and improve control over these technologies. Next year, 700 billion UZS ($54 million) in subsidies and 2.5 trillion UZS ($195 million) in credit will be used for water-saving technology. Additionally, flood reservoirs will be built in 13 districts, improving the water supply for 50,000 hectares. Mirziyoyev emphasized that real change requires digitization. About 1,700 online monitoring devices and 12,000 smart water devices are already in place, but Uzbekistan needs a system to collect and analyze this data. To address this, a Water Management Digitization Center will be set up to manage a new unified system for tracking water use.

200 Million Cubic Meters of Water Directed to the Aral Sea

In 2024, agrarians from the Kyzylorda region of Kazakhstan introduced water-saving technologies on 55,000 hectares of rice fields, saving over 200 million cubic meters of water. These saved resources were directed to the Aral Sea, helping to improve its water levels. During this year's irrigation season, about a billion cubic meters of water were delivered to the Northern Aral, three times more than last year. Since the beginning of the year, the volume of water sent to the sea has reached 2 billion cubic meters, and the total water in the sea has reached 22 billion cubic meters. Kazakhstan's Minister of Water Resources and Irrigation, Nurzhan Nurzhigitov, emphasized that this result was made possible not only by effective water diplomacy with neighboring Central Asian countries but also by actively using water-saving technologies. To encourage their use, the government has increased subsidies to farmers. In 2024, subsidies rose from 50% to 80%, and in the next three years, will be brought to 85% for small-scale farms using efficient irrigation methods. These measures aim to further restore the Aral Sea's water level, which is one of the region's leading environmental objectives. Successes in water conservation demonstrates that innovative technologies can be crucial for addressing perennial water scarcity and ecosystem restoration. Water diplomacy in Central Asia plays a crucial role in solving the problem of water level reduction in the Aral Sea. Uzbekistan is actively cooperating with Kazakhstan, Tajikistan, and Kyrgyzstan on the rational use of water resources in the Amu Darya and Syr Darya river basins. One critical steps was the signing of an agreement on the exchange of electricity between the countries, which has allowed the volume of water used for irrigation to be regulated, and improved the state of the region's ecosystem. In addition, Kazakhstan and Uzbekistan are actively introducing water-saving technologies to optimize water consumption in agriculture, which is freeing up resources to replenish the Aral Sea. These measures have helped to increase water inflow to the Northern Aral Sea in recent years, maintaining its level and improving conditions for local ecosystems.
