Kyrgyzstan-Germany Project Studies Lake Issyk-Kul Ecosystem

A comprehensive scientific study of Lake Issyk-Kul began on June 11 as part of an international project involving Razzakov Kyrgyz State Technical University (KSTU), the International Medical University, and Germany’s Leibniz Institute of Freshwater Ecology and Inland Fisheries. Lake Issyk-Kul is Kyrgyzstan’s largest lake and its leading tourist destination. It also forms part of a protected ecological area. In recent decades, the lake has faced growing climate-related pressures. According to KSTU, cooperation between the scientific institutions began in 2024 with the establishment of the Issyk-Kul Ecological Laboratory in Cholpon-Ata. The laboratory has since become a platform for joint research into the lake’s ecological condition. In 2025, the partners secured a grant from the German Research Foundation to conduct a comprehensive study of the Issyk-Kul ecosystem. German scientists have arrived in Kyrgyzstan to take part in the research. The project focuses on the hydrophysical, hydrochemical, hydrobiological, and hydro-optical properties of Issyk-Kul’s water using advanced scientific methods and technologies. Researchers are also studying biological processes within the aquatic ecosystem, including DNA and RNA analysis of biomaterials. The research is expected to help assess ongoing ecological processes, identify long-term trends, and establish a scientific basis for measures to preserve the lake’s ecosystem. According to KSTU Professor Salmor Alymkulov, the project is important for expanding international scientific cooperation, training young researchers, and developing recommendations to protect Kyrgyzstan’s natural heritage. Kyrgyzstan views the preservation of Issyk-Kul as part of the global climate and water agenda. In December 2025, the Cabinet of Ministers approved the Concept for the Sustainable Development of the Ecological and Economic System of Lake Issyk-Kul through 2030, along with an accompanying action plan. The initiative is aimed at protecting the lake and its surrounding biosphere from growing environmental and human pressures while supporting the region’s long-term economic resilience. Speaking at the World Governments Summit in Dubai in February 2026, Kyrgyzstan’s then Deputy Chairman of the Cabinet of Ministers and Minister of Water Resources, Agriculture, and Processing Industry, Bakyt Torobaev, warned of the growing climate risks facing Issyk-Kul. According to Torobaev, the lake’s water level has fallen by nearly 14 meters since the mid-19th century, while its total volume has decreased by approximately 85 billion cubic meters. The number of rivers flowing into the lake has also declined significantly, largely due to glacier melt and increased agricultural water use. He warned that further declines in Issyk-Kul’s water level could have serious environmental and socioeconomic consequences, including threats to biodiversity, the lake’s tourism potential, and the well-being of local communities.

Lake Balkhash

Kazakhstan and France Develop Master Plan to Preserve Lake Balkhash

Kazakhstan and France are developing a long-term strategy to preserve Lake Balkhash, one of Eurasia’s largest inland water bodies, as concerns grow over the impact of climate change and shifting water resources in the region. An open meeting of the working group tasked with preparing a master plan for the conservation of the lake’s ecosystem was held in Astana. The project is being implemented through cooperation between Kazakhstan’s Ministry of Water Resources and Irrigation, the French Development Agency, and France’s Bureau of Geological and Mining Research. Lake Balkhash, located in southeastern Kazakhstan, is the world’s second-largest non-drying saline lake after the Caspian Sea and ranks among the largest lakes globally. The lake is unique in that its western section contains almost fresh water, while the eastern part is brackish. The Ili River provides up to 80% of Balkhash’s inflow, while the Karatal, Aksu, Ayagoz, and Lepsy rivers, along with groundwater resources, also contribute to the lake’s water balance. Although Kazakhstan’s Ecology Ministry has previously said Lake Balkhash is not at risk of catastrophic shallowing, the government has moved forward with plans to develop a comprehensive strategy for protecting the ecosystem of one of the country’s most important water resources. At the meeting, French experts presented preliminary findings from research covering key components of the project. Participants reviewed studies on agriculture, hydrology, glacier runoff contributions, hydrogeology, water use, and water-resource modeling. Particular attention was paid to the sustainable management of water resources in the Lake Balkhash basin under changing climate conditions. Experts outlined approaches to forecasting river flows, assessing future changes in glacier-fed water supplies, studying interactions between surface and groundwater resources, and applying advanced modeling tools to support water-management decisions. The meeting also examined the potential use of digital technologies to analyze different water-allocation scenarios and assist in the preparation of basin management plans. Researchers have already integrated findings from various studies into a unified assessment system covering the entire Lake Balkhash watershed. Participants identified several priority issues requiring additional analysis as work on the master plan continues. “Following the visit by the French experts, the next stages in developing the master plan will be clarified, including the preparation of forecast scenarios for the water-management situation through 2040, the selection of climate models, and additional research in specific areas,” said Kairatgali Khairulla, Chairman of the Information and Analytical Center for Water Resources under Kazakhstan’s Ministry of Water Resources and Irrigation. “Joint work by Kazakh and French experts will continue through the end of 2026 to integrate research findings, improve modeling calculations, and prepare the final document. The master plan will provide a scientific foundation for long-term decisions on preserving the Lake Balkhash ecosystem and ensuring sustainable management of water resources throughout the basin,” he added. The final version of the master plan is expected to be completed by the end of this year. The future of Lake Balkhash has gained additional significance amid major infrastructure projects planned for the region. As previously reported by The Times of Central Asia, Kazakhstan has...

Kazakhstan, Tajikistan, and Uzbekistan Agree on Summer Water Releases from Bahri Tojik Reservoir

Kazakhstan, Tajikistan, and Uzbekistan have agreed on water releases from Tajikistan’s Bahri Tojik reservoir for the June-August 2026 irrigation period, Kazakhstan’s Ministry of Water Resources and Irrigation has announced. The agreement was formalized in a trilateral protocol signed by Kazakhstan’s Minister of Water Resources and Irrigation Nurzhan Nurzhigitov, Tajikistan’s Minister of Energy and Water Resources Juma Daler, and Uzbekistan’s Minister of Water Resources Shavkat Khamrayev. Under the agreed schedule, water from the Bahri Tojik reservoir will be released during the summer to support agricultural producers in Kazakhstan’s Turkestan region, particularly in the Maktaaral and Zhetysai districts, where irrigation demand rises sharply during the growing season. “The issue of supplying irrigation water to the southern regions remains under special control,” Nurzhigitov said in comments released by Kazakhstan's ministry. “The agreements reached are the result of constructive interaction and mutual support between Central Asian countries. The measures taken will help ensure a stable growing season and support domestic farmers.” The ministers also reaffirmed their intention to strengthen regional cooperation on the rational and mutually beneficial use of shared water resources, a longstanding challenge in Central Asia, where agriculture depends heavily on transboundary rivers and reservoirs. The Bahri Tojik reservoir, formerly known as the Kairakkum reservoir before being renamed in 2016, is one of Tajikistan’s largest artificial water bodies. Located in the northern Sughd region on the Syr Darya River, it has operated since 1959 and plays an important role in seasonal water distribution across the region. The latest agreement follows a similar arrangement reached in June 2025, when the three countries approved the coordinated use of reservoir water during the summer irrigation season. At the time, Kazakhstan expected to receive 491 million cubic meters of water to help offset shortages in southern farming areas.

Kazakhstan Sets Irrigation Limits for Southern Regions and Reduces Water-Intensive Crops

Kazakhstan has introduced limits on irrigation water use in its southern regions and is reducing the cultivation of water-intensive crops as authorities seek to prevent shortages during the 2026 growing season. At a government meeting on May 12, Minister of Water Resources and Irrigation Nurzhan Nurzhigitov said reservoirs in the country’s southern regions had accumulated 26.2 billion cubic meters of water, 500 million cubic meters more than during the same period last year. Agriculture in Kazakhstan’s arid southern regions depends heavily on water collected during the spring snowmelt period, as well as water flowing from upstream Kyrgyzstan. To avoid irrigation shortages, the government established water-consumption limits for the main agricultural regions. The Turkestan region received a limit of 3.8 billion cubic meters, followed by the Kyzylorda region with 3.2 billion cubic meters, the Almaty region with 2.1 billion cubic meters, the Zhetisu region with 1.8 billion cubic meters, and the Zhambyl region with 900 million cubic meters. Authorities said all preparatory work for the irrigation season has been completed. This included mechanized cleaning of 1,840 kilometers of irrigation canals, reconstruction of 680 kilometers of irrigation networks, and repairs to 375 hydraulic facilities. To ensure stable water supplies through the canal system, 181 pumping units have been prepared, while an additional 92 pumps are expected to be purchased. Since the beginning of the year, Kazakhstan has also shifted the process of concluding water-supply contracts with farmers to an electronic format. The new digital system covers the entire water-supply cycle, including applications, contract execution, monitoring of actual water consumption, and payment processing. To date, more than 25,000 electronic contracts have been signed with farmers. “To increase transparency and strengthen operational control over water-resource management, satellite monitoring based on Earth remote sensing is being introduced across all five southern regions of the country. Since the beginning of the year, satellite monitoring has identified 39 cases of water withdrawal without contracts in the Turkestan region, where farmers illegally used approximately 790,000 cubic meters of water,” Nurzhigitov said. At the same government meeting, Deputy Agriculture Minister Azat Sultanov said Kazakhstan plans to sow crops on a total area of 23.8 million hectares this year, 180,000 hectares more than in 2025. Priority is being given to more profitable crops. The area under oilseed cultivation will exceed 4 million hectares, while forage crops will cover 3.3 million hectares. Kazakhstan is also continuing efforts to diversify agricultural production. The area planted with grain crops will be reduced by 127,000 hectares. As part of water-saving measures, the government is cutting back on water-intensive crops such as rice and cotton. Rice cultivation areas have been reduced by 20,200 hectares. At the same time, the area under drip-irrigated cotton has increased by 29,800 hectares, while cotton grown using traditional irrigation methods has been reduced by 12,000 hectares.

Kapchagay Reservoir

Kazakhstan’s Kapchagay Reservoir Reaches 98% Capacity

Kazakhstan’s Kapchagay Reservoir in the Almaty Region is now 98% full, holding 18.04 billion cubic meters of water, according to the Ministry of Water Resources and Irrigation. The reservoir collects water from the transboundary Ili River, which originates in China, and regulates water flow into Lake Balkhash, Kazakhstan’s largest lake. During the most recent non-growing season, approximately 4 billion cubic meters of water were released from the reservoir into Lake Balkhash. Officials say the near-full capacity of the reservoir will ensure sufficient irrigation supplies for agricultural land in the Akdala and Shengeldy rural districts of the Almaty Region. “We maintain constant communication with our Chinese colleagues on transboundary river issues, including the Ili River. Thanks to the coordinated efforts of the two countries, farmers in the Almaty Region have been provided with a stable supply of irrigation water for the third consecutive year,” said Seilbek Nurymbetov, chairman of the ministry’s Committee for Regulation, Protection, and Use of Water Resources. The Times of Central Asia previously reported that the Kapchagay Reservoir reached full capacity in August 2024 for the first time in a decade. Created in 1970 as an artificial lake stretching roughly 100 kilometers in length and up to 25 kilometers wide in some areas, the reservoir has a total capacity of more than 18 billion cubic meters of water. The reservoir was originally designed to regulate the flow of the Ili River before it reaches Lake Balkhash. Today, it also serves irrigation, fish farming, and recreational purposes. Located about an hour’s drive from Almaty, its beaches are a popular destination for tourists and local residents. Three of Kazakhstan’s major rivers, the Irtysh, Ili, and Emel, originate in China. The Ili River alone provides about 70% of the water flowing into Lake Balkhash. Located approximately 280 kilometers northwest of Almaty, Lake Balkhash is the world’s fifteenth-largest lake.

Kyrgyz MP Questions Why Uzbekistan and Kazakhstan Don’t Pay for Irrigation Water

A long-standing debate over Kyrgyzstan’s water resources resurfaced this week after a member of parliament questioned why Uzbekistan and Kazakhstan do not compensate Kyrgyzstan for irrigation water sourced from its reservoirs, according to a report by Kaktus Media. Speaking at a February 9 meeting of the parliamentary committee on agrarian policy, water resources, ecology, and subsoil use, MP Umbetaly Kydyraliev raised concerns about growing water shortages caused by climate change and the lack of economic return from water exports to neighboring countries. “About 80% of the water in our reservoirs goes to Kazakhstan and Uzbekistan,” said Kydyraliev. “How are we resolving this issue with them?” Regional Cooperation vs. Compensation In response, Deputy Prime Minister and Minister of Water Resources, Agriculture, and Processing Industry Bakyt Torobaev explained that while Uzbekistan and Kazakhstan are not making direct payments for water, they are contributing to major regional infrastructure projects, most notably, the Kambar-Ata-1 hydropower plant. Torobaev emphasized that cooperation is based on mutual benefit rather than transactional agreements. He noted that both countries have expressed strong interest in ensuring reliable access to water and have supported the hydropower initiative accordingly. Kambar-Ata-1: Strategic Investment Kambar-Ata-1, originally launched during the Soviet era and later shelved, is poised to become one of Central Asia’s largest hydropower plants. Once completed, it is expected to surpass the output of the Toktogul hydropower station, currently Kyrgyzstan’s main source of electricity. The plant's projected cost is around $3.6 billion. Who Should Pay for Upkeep? Kydyraliev also cited other key reservoirs, including Kempir-Abad (jointly managed with Uzbekistan), Kirov, and Orto-Tokoy, which remain under Kyrgyzstan’s jurisdiction. Annual intergovernmental commissions determine how much water is released from these facilities, yet no financial compensation is received. “Does this mean Kyrgyzstan gains no economic benefit from maintaining these hydropower facilities?” he asked. “We have to repair them, stabilize water levels, and inspect dams. These are real costs. Other countries pay for water under international law.” Official Position: No Demands for Payment Deputy Energy Minister Nasipbek Kerimov noted that the issue is being jointly studied by energy and water specialists. Torobaev added that details of these discussions are confidential but confirmed that President Sadyr Japarov has instructed officials not to demand payments from neighboring states for infrastructure maintenance. Instead, Kyrgyzstan will shoulder those costs itself, with any external assistance remaining voluntary.
