Isfana River

The Isfana River (Kyrgyz, Uzbek: Isfana soyi), also called Isfanasay is a north-flowing transboundary river in Central Asia. It is approximately 69 kilometres (43 mi) long and flows through Razzakov, which was also called Isfana until 2022. The river's course runs through Kyrgyzstan and Tajikistan, from the Turkestan Range into the Syr Darya. Most of the river's water is diverted for irrigation or seeps into the ground, and as such it rarely reaches the Syr-Darya. The Isfana is fed by unnamed glaciers on the northern flank of the Turkestan Range as well as groundwater. It has 31 tributaries, most of which meet in and around Razzakov. One of the several transboundary rivers in the Syr-Darya basin, the Isfana River flows parallel to the Khojabakirgan River. International donor organizations have supported the establishment of small basin councils in the Isfana River basin, particularly in Tajikistan.
