Tortkul Reservoir is a unique structure.
It is located in the Batken region on the Isfara River.
The area of the reservoir is 6.6 square kilometers, and its volume is 90 million cubic meters of water. Since the river is fed by glacial and snow melt, the reservoir is primarily filled due to melting snow and other sources. Approximately 60 million cubic meters are used annually during the irrigation season, leaving about 30 million in reserve. The critical volume is 15 million cubic meters of water.
The Tortkul Reservoir remains a unique structure to this day. Its bottom is covered with hundreds of hectares of special film.
It is known that the reservoir, built in the early 1970s, allowed for the emergence of apricot orchards and vineyards, and the cultivation of many hectares of land. New villages also appeared in the Batken region due to the reservoir.
However, recently the water level in the reservoir has noticeably decreased each year. The western part of the reservoir has become clogged with clay and sand. Meanwhile, according to the Department of Water Management, in recent years the water level in the Tortkul Reservoir has increased significantly.
