Everything about Tajikistan's water, glaciers, energy and climate.
Tajikistan is the source of Central Asia's largest river systems — holding 55.4% of total Aral Sea basin drainage and feeding tens of millions of people downstream.
Tajikistan's high-altitude geography concentrates an enormous freshwater inventory. Snow- and glacier-fed rivers generate 64 km³ of annual runoff, a baseline volume that supports irrigation, energy, and drinking water across five downstream countries.
Amu Darya (formed by Panj + Vakhsh) is the dominant transboundary system. Syr Darya contributes ~1% from Tajik territory. Zerafshan flows west into Uzbekistan; Kofarnihon drains the south. Smaller tributaries feed irrigation networks across Sughd and Khatlon.
Karakul (3,914 m — one of the world's highest lakes), Sarez (landslide-dammed, 17 km³, potential GLOF risk), Iskanderkul (alpine glacial lake in the Fann Mountains) are the most significant.
Under the ICWC framework, Tajikistan receives only 15–18% of the allocable Amu Darya flow despite generating ~55% of total basin water — a recurring source of regional tension.
Tajikistan supplies water to Uzbekistan, Kazakhstan, Afghanistan, Turkmenistan, and Kyrgyzstan. Summer/winter trade-offs between irrigation (downstream) and energy (upstream) drive policy negotiation.
Century of water policy & infrastructure milestones
Tajikistan has 947 rivers with a length of 10 km and more. Rivers shorter than 10 km are not included in this count. This classification follows international hydrological standards.
