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.
