July 23, Colombo: President Maithripala Sirisena will inaugurate filling water to the Kalu Ganga reservoir that is being built in parallel to the Moragahakanda reservoir under the Moragahakanda-Kalu Ganga multi-purpose irrigation project today.
In addition, the Moragahakanda Reservoir will be named after the renowned civil engineer Dr. ANS Kulasinghe. The President will also unveil a 27 feet tall granite replica of the Avukana Buddha Statue on one edge of the Moragahakanda Reservoir bund.
The hydro-electricity plant, which generates 25 Megawatt hydro-power will also be added to the national grid today by the President.
The Moragahakanda-Kalu Ganga multi-purpose irrigation project at a cost of US$ 1.2 billion was designed to harvest water from Amban Ganga and Kalu Ganga, two tributaries of Mahaweli Ganga, with the construction of Moragahakanda and Kalu Ganga reservoirs, for irrigation and power generation purposes.
The Kalu Ganga reservoir is created by blocking the river which starts from the Knuckles range of the Dumbara valley at Laggala Pallegama area.
The total capacity of the reservoir is 248 million cubic meters. The main dam is 618 meters long and 68 meters high. The top of the dam is 8 meters wide. The catchment area is 128 square km and the size of the reservoir is 14.5 square km.
The Kalu Ganga reservoir will supply water to 3,000 families who have been resettled in the lower valley of the river.
It is planned to take water from old Haththota anicut and after supplying water to over two thousand acres of cultivated land, release excess water to the Moragahakanda Reservoir.
Construction of the 9 km canal with the tunnel that links the two reservoirs will also commence today.
The water of the Kalu Ganga reservoir will be released through the tunnel to the Moragahakanda reservoir at a rate of 35 cubic meters per second.
The construction of the Moragahakanda Reservoir was completed last year.
The Moragahakanda-Kalu Ganga project will provide irrigation facilities to 81,422 hectares in the dry zone of Sri Lanka, provide potable and industrial water supply to Anuradhapura and Trincomalee towns and generate electricity by hydropower while opening up 5000 hectares of new land for agriculture development in Northern, North Central, Eastern and North Western provinces.
