Karun-4 Dam

Karun-4 Dam is located in Chaharmahal and Bakhtiari Province, on the Karun River, Iran's largest river by water volume. It lies about 180 kilometres southwest of Shahrekord. The dam is a double-arch concrete dam and, at 230 metres high from its foundation, is the tallest concrete dam in Iran. The dam entered full operation in the summer of 1390 (2011).

Karun-4 Dam was built to generate hydroelectric power, control floods and supply water downstream. The reservoir behind the dam covers an area of about 29 to 30 square kilometres and holds nearly 2.19 to 2.2 billion cubic metres of water. Its power plant is equipped with four generating units, which are approaching a nominal capacity of 1,000 megawatts. Beyond its technical functions, the dam lake and its reservoir have created beautiful natural scenery, which is considered one of the region's tourist attractions.

To visit Karun-4 Dam, the usual access route is the road from Shahrekord heading southwest toward the town of Lordegan, since the dam is located near this area. The best time to visit is during the mild seasons, spring and autumn, when the weather is cooler and the forested and mountainous landscapes around the lake look their most beautiful. Nature tourism around the reservoir, while respecting environmental protection principles and avoiding damage to vegetation and wildlife, offers visitors a relaxing and responsible experience.
