During the construction work of Headrace tunnel. The 4.5–5.2 m (14.8–17.1 ft) diameter, 12.89 km (8.0 mi) long Upper Kotmale Tunnel, the longest excavated tunnel in Sri Lanka, will be used to deliver the water to the powerhouse.
The reservoir's full supply level is 460 metres (1,510 ft) above main sea level, and the reservoir spreads 8 kilometres (5.0 mi) upstream at this level. The reservoir is u-shaped. [5] It covers an area of 897 ha. However, with the water leakage the water level was reduced to 430 metres (1,410 ft). [2] It is one of the largest reservoirs in Sri ...
The Moragolla Dam is a planned hydroelectric dam in Moragolla, Sri Lanka.The dam is to be 35 m (115 ft) high and is planned to create the 1,980,000 m 3 (70,000,000 cu ft) Moragolla Reservoir with a maximum supply level at 548 m (1,798 ft) MSL. [1]
Sri Lanka is pockmarked with many irrigation dams, with its water resource distributed across nearly the entirety of the island for agricultural purposes via artificial canals and streams. Utilization of hydro resources for agricultural production dates back to the pre-Colonial era , with the current crop production now largely dependent on ...
The maiden water release of the dam was in January 2017. [3] Morgahakanda/Kaluganga project is the last of the Great Mahaveli project [ 4 ] The larger combined project involves the construction of the Moragahakanda Dam and Reservoir, along with the separate Kalu Ganga Dam and Reservoir , for irrigation and power generation purposes.
The dam creates the iconic Castlereigh Reservoir, which is almost entirely maintained by the inflow of water from the Kehalgamu Oya. Water from the reservoir is diverted to the Wimalasurendra Power Station, located approximately 12 km (7.5 mi) downstream at 06°54′31″N 80°31′30″E / 6.90861°N 80.52500°E / 6.90861; 80.52500 ...
The Polgolla Barrage (also erroneously known as the Polgolla Dam) is a barrage built across the Mahaweli River at Polgolla, in the Central Province of Sri Lanka.The main purpose of the barrage is to maintain the water level of Mahaweli river at a constant height to provide a uniform potential head at the intake to the underground tunnel which conveys water to Ukuwela powerplant.
The Deduru Oya Dam is an embankment dam built across the Deduru River in Kurunegala District of Sri Lanka. Built in 2014, the primary purpose of the dam is to retain for irrigation purposes approximately a billion cubic metres of water, which would otherwise flow out to sea. Site studies of the dam began in 2006 and construction started in 2008.
