List Of Dams And Reservoirs In Sri Lanka
The following page lists most dams in Sri Lanka. Most of these dams are governed by the Mahaweli Authority, while the Ceylon Electricity Board operates dams used for hydroelectric power generation. Hydroelectric dams, including small hydros accounts for nearly half of the installed power capacity of Sri Lanka. 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 pre-Colonial era, with current crop productions now largely dependent on these water resources. __NOTOC__ Dams in Sri Lanka Irrigation dams with a length and height of more than and are listed, including all the state-run hydroelectric power stations. Privately owned "small-hydro" facilities (which are limited to a maximum nameplate capacity of ), are not included in this list. Nearly all hydroelectric dams are ...

Electricity Sector In Sri Lanka
The electricity sector in Sri Lanka has a national grid which is primarily powered by hydroelectric power and thermal power, 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. The country is expected to achieve 75% electricity generation by renewable energy by 2025. History Sri Lanka (then Ceylon) first witnessed electricity in 1882 when SS Helios docked in Colombo for a local electricity exhibition. In 1890, using a diesel generator the first electric bulb in Ceylon was lit with electricity in the Billiard Room of Bristol Hotel in Colombo, before electric lights became an established commercial product. In 1895, Messrs Boustead Bros established a small power station in Bristol Building, Fort. The power station was the first commercial power station ...

Arch-gravity Dam
An arch-gravity dam or arched dam is a dam with the characteristics of both an arch dam and a gravity dam. It is a dam that curves upstream in a narrowing curve that directs most of the water pressure against the canyon rock walls, providing the force to compress the dam. It combines the strengths of two common dam forms and is considered a compromise between the two. They are made of conventional concrete, roller-compacted concrete (RCC), or masonry. Arch-gravity dams are not reinforced except at the spillway. A typical example of the conventional concrete dam is the Hoover Dam. Changuinola Dam is an example of the RCC arch-gravity dam. A gravity dam requires a large volume of internal fill. An arch-gravity dam can be thinner than the pure gravity dam and requires less internal fill. Overview Arch-gravity dams are dams that resist the thrust of water by their weight using the force of gravity and the arch action. An arch-gravity dam incorporates the arch's curved design ...

The dam measures and in length and height respectively, with four spillways, and a sand trap on the left-bank. Each spillway gate measures high and wide, and uses the same automated technology as the Victoria Dam. The dam creates the Kukule Ganga Reservoir, which has a capacity and catchment area of and respectively. After passing through the dam and sand traps, water from the reservoir is fed into a long tunnel, which leads to the underground power station. The tunnel from the dam to the power station, with an internal diameter of , creates a gross head of . Power station Water from the tunnel is fed into the underground power station, con ...

Kotmale Dam
The Kotmale Dam is a large hydroelectric and irrigation dam in Kotmale, Sri Lanka. The dam generates power from three turbines, totalling the installed capacity to , making it the second largest hydroelectric power station in Sri Lanka. Construction on the dam began in August 1979 and was ceremonially completed in February 1985. The dam forms the Kotmale Reservoir, which was renamed to Gamini Dissanayake Reservoir on 11 April 2003 following a request by Prime Minister Ranil Wickramasinghe.

Uma Oya Hydropower Complex
The Uma Oya Hydropower Complex (also internally called Uma Oya Multipurpose Development Project or UOMDP) is a irrigation and hydroelectric complex currently under construction in the Badulla District of Sri Lanka. Early assessments of project dates back to 1989, when the first studies was conducted by the country's Central Engineering and Consultancy Bureau. The complex involves building a dam across Dalgolla Oya, and channelling water over a tunnel to Mathatilla Oya, both of which are tributaries of the Uma Oya. At Mathatilla Oya, another dam is constructed to channel of water per annum, via a headrace tunnel to the Uma Oya Power Station, where water then discharged to the Alikota Aru via a tailrace tunnel. The Alikota Aru is a tributary of the Kirindi Oya. The construction of the complex was inaugurated in April 2008 by former President Mahinda Rajapaksa and President Mahmoud Ahmadinejad.
