Lake Bakhtegan is a salt lake in Fars Province, southern Iran, about 160 km (99 mi) east of Shiraz and 15 km (9.3 mi) west of the town of Neyriz. Bakhtegan, with a surface area of 3,500 square kilometres (1,400 sq mi), is Iran's second-largest lake. It is fed by the Kor River. Several dams on the Kor River have significantly reduced waterflow into the lake, increasing its salinity and endangering the lake's populations of flamingos and other migratory birds.
