List of dams and reservoirs in Iran
Major dam construction started in Iran in the 1950s. Some fourteen large dams were built with the help of foreign engineers and advisors during two decades preceding the Islamic Revolution in 1979. In the post-revolution era, Iran's dam building capacity was significantly strengthened, with some 200 contracting companies, 70 consultant firms and 30 corporations as well as hundreds of hydroelectric manufacturing units having been established inside of Iran in less than three decades. In addition to the necessity of generating electricity, Iran needs dams to effectively control and manage a growing water shortage across the country.Iran was constructing 88 small and large dams in 2007. On average, close to two billion cubic meters of water are added to the country’s water reserves annually.

International projects
One of Iran's most important international projects will see the construction of a $200 million hydroelectric dam in Nicaragua, starting in 2011. Iran is currently engaged in dam construction in Tajikistan, Armenia and Azerbaijan, and consultations are under way with a number of other countries. Kenya, Sri Lanka, Bolivia and Mali are the potential target markets being considered for exporting the country's technical and engineering services. In 2010, Iran won a contract to build a dam in Afghanistan and the third contract to build a power plant station in Syria.
