The Almendra Dam, also known as Villarino Dam, in Salamanca, Spain, interrupts the course of the River Tormes five kilometres from the village from which it takes its name: Almendra (literally, almond). It was constructed between 1964 and 1970. The dam forms part of the hydroelectric system known as the Duero Drops, along with the Castro, Ricobayo, Saucelle and Villalcampo dams of Spain, and the Bemposta, Miranda and Picote dams of nearby Portugal. The reservoir that backs up behind the dam covers 86.5 square kilometres and contains 2.5 billion cubic metres of water as well as several drowned villages, among them Argusinos. The dam is more than half a kilometre wide and, at a height of 202 metres, one of Spain's tallest structures. The water is used by the Villarino I Power Station for electricity generation. It has a generation capacity of 810 MW.
