Lake Alassa – Kouris Dam


Lake Alassa – Kouris Dam

Kouris is the largest dam of a network of 107 dams in Cyprus. It lies at an altitude of 250 metres (820 ft) and collects the water delivered by Kouris, Limnatis and Kryos rivers. Furthermore, water from Diarizos river is diverted to Kouris dam via a 14.5 kilometres (9.0 mi) long connecting tunnel. It has an overall catchment area of 300 kilometres (190 mi). The dam is located 15 kilometres (9.3 mi) northwest of the city of Limassol and 6 kilometres (3.7 mi) west of the village of Ypsonas. The dam has a central clay core zoned earthfill embankment with a height of 110 metres (360 ft) and a crest length of approximately 550 metres (1,800 ft). For its construction the whole village of Alassa had to be relocated to a nearby site overlooking the reservoir (between the Kouris and Limnatis valleys) at a cost of around CYP£5,000,000.

The dam is part of the Southern Conveyor Project, which carries water from the SW side of Cyprus to the SE part of the island, over a distance of 120 km. The dam has a central clay core zoned earthfill embankment with a height of 110m and a crest length of approximately 550 metres providing a water storage volume of 115 million cubic metres.

The construction cost amounted to CYP £29,000,000. Part of the funding came from the European Investment Bank. Construction was completed in September 1988. Since its construction it has overflowed twice, on March 4, 2004 [9] and on April 6, 2012.
