Siasak Dam is located 7 km southwest of Divandareh. The purpose of its construction is to supply agricultural water and drinking water. The dam of Siazak-Divandareh has a reservoir volume of 230 million cubic meters and a spill capacity of 1800 cubic meters per second. The annual water in the second phase of operation is 143 million cubic meters, due to the use of hydraulic reservoir pressure in the transmission system, its power plant has been eliminated.
There is also a pebble dam that has a height of 84 meters and a crown length of 285 meters.
