The Castlereigh Dam (also spelled Castlereagh) is a gravity dam built across the Kehelgamu Oya, a major tributary to the Kelani River, approximately 3 km (1.9 mi) south-west of Hatton, in the Central Province of Sri Lanka. [1]

Reservoir and power station

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) further downstream at 06°54′31″N80°31′30″E / 6.90861°N 80.52500°E / 6.90861; 80.52500 (Wimalasurendra Hydroelectric Power Station) , near Norton Bridge. The power station discharges the water into the Norton Reservoir, created by the Norton Dam, located at the same site. [1]

The power station consists of two 25-megawatt units, totalling the plant capacity to 50 MW . Both units were commissioned in January 1965. [2]

Water airport

The Castlereigh Reservoir is also home to the Castlereigh Water Airport, registered under the IATA code NUF. [3]

Electricity sector in Sri Lanka

The electricity sector in Sri Lanka has a national grid which is primarily powered by hydro power and thermal heat, with sources such as photovoltaics and wind power in early stages of deployment. Although potential sites are being identified, other power sources such as geothermal, nuclear, solar thermal and wave power are not used in the power generation process for the national grid.

Kehelgamu Oya

The Kehelgamu Oya is a major upstream tributary of the Kelani River. The tributary measures 50 km (31 mi) in length, originating from the hills of the Horton Plains National Park, before passing through the Castlereigh Reservoir. Kehelgamu Oya converges with the Maskeliya Oya at Kalugala, forming the 100 km (62 mi) long Kelani River. The river is heavily used for hydroelectric power generation.

Maskeliya Oya

The Maskeliya Oya is a major upstream tributary of the Kelani River. The tributary measures approximately 40 km (25 mi) in length, originating from the hills of the Peak Wilderness Sanctuary, before passing through the Maskeliya Reservoir. Maskeliya Oya converges with the Kehelgamu Oya at Kalugala, forming the 100 km (62 mi) long Kelani River. The river is heavily used for hydroelectric power generation.

The Kukule Ganga Dam is a 110 m (360 ft) gravity dam built across the Kukule River in Kalawana, Sri Lanka. The run-of-river-type dam feeds an underground hydroelectric power station located approximately 5 kilometres (3.1 mi) away, via tunnel.

Udawalawe Dam Dam in Udawalawe

The Udawalawe Dam is a large irrigation dam in Udawalawe, in the Southern Province of Sri Lanka. The dam consists of an embankment section and a gravity section, combining the total dam length to approximately 3.9 km (2.4 mi). The dam is also used for hydroelectric power generation, powering three 2 MW units, commissioned in April 1969.

Gal Oya Dam Dam in Gal Oya National Park

The Gal Oya Dam is an embankment dam in the Uva Province of Sri Lanka. The dam creates one of the largest and most iconic reservoirs in the country, the Gal Oya Reservoir. Water from the reservoir is used primarily for irrigation in the Uva and Eastern provinces, in addition to powering a small hydroelectric power station. Construction of the dam and reservoir began in August 24, 1949, completing four years later in 1953.

Nilambe Dam Dam in Nilambe, Central Province

The Nilambe Dam is a small hydroelectric dam build across the Nilambe River, measuring approximately 70 m (230 ft) in length. Water from the Nilambe Dam is transferred to the 3.2-megawatt Nilambe Power Station through a penstock measuring approximately 2.8 km (1.7 mi). The power station consists of two 1.6 MW generating units, which were commissioned in July 1988.

Deduru Oya Dam Dam in Wariyapola

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 approximately a billion cubic metres of water for irrigation purposes, which would otherwise flow out to sea. Site studies of the dam began in 2006 and construction started in 2008. It was ceremonially completed in 2014, with the presence of the then President Mahinda Rajapaksa.
