Geography

The river's source lies in Kyrgyzstan; it then flows through Tajikistan for a length of 524 km (325 miles) before joining the Panj River to form the Amu Darya at the border of Tajikistan and Afghanistan. The average annual discharge of the Vakhsh is 16.9 km³, derived from an average discharge of 536 m³/sec.[citation needed] The river, which is fed mostly by melting glaciers, achieves maximum flow during the summer months of July and August. The river flows through very mountainous territory, which frequently restricts the river's flow to narrow channels within deep gorges. Within Tajikistan, the river's catchment area is 31,200 square kilometers. The largest tributaries of the Vakhsh are the Muksu and the Obihingou.

Dams

The hydroelectric power potential Vakhsh River has been thoroughly exploited by the Soviet Union and its successor Tajikistan. There are currently five completed hydroelectric dams along the Vakhsh within Tajikistan, including the world's tallest completed dam, the Nurek. The five dams supply 90% of the country's electric power generation capacity. In addition, another four dams are planned or under construction, including the Rogun Dam, which will supersede the Nurek as tallest in the world once it is completed.

Blockages

The Vakhsh is subject to blockage by landslides caused by earthquakes in the seismically active region. Such landslides pose a significant threat to the river's dams and hydroelectric power generation. In response to an earthquake-caused landslide in 2002, Tajikistan was granted a low-interest loan from the Asian Development Bank to mitigate the potential impact of the landslide.
