The Karun-3 dam is a hydroelectric dam on the Karun river located in the province of Khuzestan, Iran. It was built to help meet Iran's energy demands as well as provide seasonal flood control. The Karun river has the highest discharge slits and seasonal flooding in Iran.
The Karun is the Iranian river with the highest water flow, and the country's only navigable river. It is 950 km (590 mi) long. The Karun rises in the Zard Kuh mountains of the Bakhtiari district in the Zagros Range, receiving many tributaries, such as the Dez and the Kuhrang. It passes through the city of Ahvaz, the capital of the Khuzestan Province of Iran, before emptying to its mouth into Arvand Rud.

Shahid Rajaee Dam, also known as the Soleyman Tangeh Dam, is an arch dam on the Tajan River, located about 38 km (24 mi) south of Sari in Mazandaran Province, Iran. The dam was built for hydroelectric power production, flood control and to provide water for industrial and agricultural use. Construction on the dam began in 1987 and it was complete in 1997. In 2000 the power plant portion of the project was given to Iran Water & Power Resources Development Co. from the Mazandaran Regional Water Authority. An earthquake halted the project in 2002 but the power plant was completed in 2007.
The Kouhrang 2 Hydroelectric Power Station is located just south of Chelgard and about 69 km (43 mi) northwest of Shahrekord in Chaharmahal and Bakhtiari Province, Iran. The power station has an installed capacity of 33.3 MW and uses water diverted to the east from the Kouhrang River, via a small dam and the 2 km (1.2 mi) long Kouhrang 2 Tunnel, to produce power. Water from the Kouhrang is stored in a circular dam before being sent to the power station. The power station's three generators were commissioned between 2002 and 2004, the power plant were inaugurated in February 2005. Water discharged from the power station enters the Zayandeh River as part of a larger project to provide water to major cities like Isfahan. The intake for the power plant is located on the Kouhrang River just downstream of the Kouhrang 1 Dam which also diverts water, via the 2,800 m (9,200 ft) long Kouhrang 2 Tunnel, to near Chelgard and was completed in 1953. The Kouhrang 3 Dam is planned downstream to regulate river flows and divert more water to the Zayandeh via the Kouhrang 3 Tunnel.
Rudbar Lorestan Dam is a hydroelectric dam on the Rudbar River, a tributary of the Dez River, in Iran's Lorestan Province with an installed electricity generating capability of 450 MW. It was scheduled to become operational in 2013. Finally, the dam was completed on September 15, 2016. The hydroelectric plant consisting of two 225-MW vertical Francis turbine-generator units has begun operating on May 31, 2017.
Upper Gotvand Dam, or simply the Gotvand Dam, is an embankment dam on the Karun River about 12 km (7.5 mi) northeast of Gotvand in Khuzestan Province, Iran. It currently has an installed capacity of 1,000 MW with another 1,000 MW in the works for a second phase. Studies for the project on Karun River began in the 1960s and specific designs on the Upper Gotvand were presented in 1967, 1975 and 1982. After the design and location were chosen, a further study was carried out in 1997. Preliminary construction began the same year. Besides the hydroelectric power production, the dam was also aimed at flood control. The river was diverted by April 2003 and excavation began soon thereafter. After completion of the dam, impounding of its reservoir began on 30 July 2011 during a ceremony attended by Iranian President Mahmood Ahmadinejad. The first generator of phase one was commissioned on 5 May 2012, two more by 18 September 2012 and the final in November 2012. Ahmadinejad was again present for the dam's inauguration on 22 April 2013. Phase 2 is estimated to be complete in 2015 and the dam is going to become one of Iran's largest power stations and is already its tallest earth-fill dam.
Khersan-3 dam is a hydroelectric arch dam currently under construction on the Khersan River, a tributary of the Karun River, in Iran. When complete it will have an installed capacity of 400 MW. It is situated near Atashgah in Chaharmahal and Bakhtiari Province and is a complementary dam to Khersan project along with the proposed Khersan-1 and Khersan-2 dams.

Gavshan Dam is an embankment dam on the Gaveh River 40 km (25 mi) south of Sanandaj in Kurdistan province, Iran. It was created for the primary purpose of irrigation but also supports an 11 MW hydroelectric power station. Water from the dam's reservoir is transferred for irrigation in Kurdistan and Kermanshah provinces via 20 km (12 mi) Gavshan Water Conveyance Tunnel. About 189,000,000 m3 (153,225 acre⋅ft) can be transferred annually for the irrigation of 310 km2 (120 sq mi). Additionally, water from the reservoir is used to provide drinking water for the city of Kermanshah in the amount of 63,000,000 m3 (51,075 acre⋅ft) annually. Construction on the dam began in 1992 and was completed in 2004. It was inaugurated by Iran's President Mohammad Khatami on 13 February 2005.

The Daryan Dam, also spelled Darian, is an embankment dam constructed on the Sirvan River just north of Daryan in Paveh County, Kermanshah province, Iran. The primary purpose of the dam is to supply up to 1,378,000,000 m3 (1,117,000 acre⋅ft) of water annually to the 48 km (30 mi) long Nowsud Water Conveyance Tunnel where it will irrigate areas of Southwestern Iran. The dam also has a 210 MW hydroelectric power station. Construction on the dam began in 2009 and the dam began to fill its reservoir in late November 2015. The Darian Dam Archaeological Salvage Program (DDASP) was planned by Iranian Center for Archaeological Research before flooding the reservoir. As a result, a number of important archaeological sites were discovered and some were excavated. The power station was commissioned in 2018. The dam's diversion tunnel was completed in June 2011. The dam was designed by Stucky of France and consultation was provided by Mahab Ghodss, International Consulting Engineering Co. In August 2010 Farab Co. won the contract to build the power station. In 2011, workers on the project held a protest against unpaid wages. The dam is also the subject of protest due to the forced relocations and ecological/cultural impact its reservoir will have.
