Moragahakanda Kaluganga Development Project
Work on the Moragahakanda Kalu Ganga Multi- Purpose Development Project which was restricted only to plans for around four decades, was launched by His Excellency President Mahinda Rajapaksa on 25th January 2007, making it a reality as mentioned in the “Mahinda Chinthana” program.
The Moragahakanda Kaluganga Development Project which is a major component of Mahaweli Master Plan has been progressing steadily and is to improve irrigation facilities to existing water scarce farmlands (82,000ha) and most importantly open up new land (5000ha) for agriculture development in Northern, North Central, Eastern and Northwestern provinces. The Project will generate25MW hydropower to the national grid. Increasing inland fish production, provision of potable and industrial water requirements, Eco tourism and effective flood control are the other targets of the project.
The financial provision allocated for 2013 is Rs.9535 million. Out of this Rs. 2725 million was released from Treasury by end of August 2013. The funds were disbursed on Moragahakanda reservoir Saddle Dam -1 and Main Dam construction, Preliminary works on Kaluganga reservoir dam construction, infrastructures development, and resettlement and environment mitigation related activities.
The Saddle Dam 2 of Moragahakanda reservoir was completed using local funds .
Sino_Hydro Corporation of China has undertaken the construction work of Moragahakanda reservoir Main Dam and Saddle Dam – 1 including 25MW Hydro Power generating unit. The contractor has completed preliminary works such as contactor’s office complex, workshop, Baylay Bridge over Amban Ganga, concrete batching plant, quarry production plant and necessary equipments and machines. Construction work of Saddle dam -1combined with hydro Power generating units and river diversion canal are in progress. The preliminary works related to Moragahakanda main dam such as survey, land clearance and geological surveying have been completed and foundation excavation is in progress.
Construction stages of Saddle dam-1 which is 51.5m height and 370m length. The Roller Compact Concrete -RCC technology will be used.
Construction work of 62m height and 404m length Rock-Filled Main Dam of Moragahakanda reservoir.
Funding arrangements have been finalized for the Kaluganga reservoir construction from the Kuwait Fund for Arab Economic Development, Saudi Fund for Development and OPEC Fund for International Development. Preliminary preparations are in progress. The detail designs and tendering process is completed, and construction tender will be awarded in near future after obtaining donor concurrences.
Transportation network is improved. Koombiyangahaela to Moragahakanda relocation road which is 13.5km is in progress with carpet laying. The 24.1km length new road from Moragahakanda up to Thorapitiya Wellewela via Guruwela new settlement area with 77 culverts and 10 bridges was constructed, and road paving to be done. Construction of new hamlet and market roads and improvement to the existing roads facilitate project activities.
Twelve minor irrigation tanks which are incorporated in to Kaluganga LB and RB main canal in the resettlement area were constructed and irrigation water conveying canals are being constructed. Another three minor irrigations tanks were constructed, and they act as level crossing tanks along the Kaudulla LB canal development.Construction of administrative buildings of Mahaweli Authority was first priority in aim of facilitating development and resettlement activities. Two Block Office related building complexes, and six Unit Office related building complexes were completed and now in full functional with related staff.
Development of Guruwela and New Laggala new towns are on progress. Construction works of post offices, health care centers, administrative buildings, schools were completed. Guruwela police station construction is in progress while police staff quarters were completed.
- Reforestation of about 1365 ha in the
immediate catchment of Amban Ganga Basin
- Demarcation of 100m buffer zone
around Moragahakanda reservoir and reforestation of 650ha inside this
buffer zone.
- Establishment of an elephant corridor
between Giritale – Minneriya nature reserve and Wasgamuwa National Park.
Habitat enrichment in the above areas.
- Rehabilitation of tanks in adjacent
nature reserves and eradication of invasive plants.
- Establishment of electric elephant fence
around the resettlement area
Introduction of new farming technology and capacity building of newly settled farmers are very important for successful resettlement process. In order to achieve this project has established a 27ha. Model farm at Guruwela resettlement area. The farm plays a vital role in farmer training, supplying of planting materials for the new settlers, introduction of organic farming and to illustrate agriculture potential in the area.

Gross storage capacity of the reservoir is 248MCM. Main aim of the project is to transfer 100MCM of water annually to Moragahakanda reservoir to cater for the downstream water demands of Moragahakanda reservoir and to release water for in basin irrigation development for 4000 ha of new and existing lands in Kaluganga. Further a provision is therefore to construct a 3MW power plant to make use of available head while releasing water to Moragahakanda. There are four Tunnels in this Project. - Kaluganga-Moragahakanda Link Canal: A Vital Component of the Moragahakanda-Kaluganga Development
-
The Kaluganga-Moragahakanda Link Canal is a crucial element of the larger Moragahakanda-Kaluganga Development Project, which is one of Sri Lanka’s most significant water resource management initiatives. This project, overseen by the Mahaweli Authority of Sri Lanka with detailed design and consultancy services provided by the Mahaweli Consultancy Bureau (MCB), aims to optimize water distribution across several districts in the country’s dry zone, ensuring water security for agriculture, drinking, and industrial use.Project OverviewProject Period: 2007-2022 Funding Sources:China Development Bank (CDB); Saudi Fund for Development (SFD); OPEC Fund for International Development (OFID); Kuwait Fund for Arab Economic Development (KFAED); Government of Sri Lanka (GoSL)Estimated Cost: LKR 117,200 millionObjectives of the Kaluganga-Moragahakanda Link CanalThe Kaluganga-Moragahakanda Link Canal is designed to connect the Kaluganga and Moragahakanda reservoirs, facilitating the efficient transfer of water between these two major storage facilities. The primary objectives of this canal are:Water Transfer and Management: The canal is essential for ensuring that water from the Kaluganga reservoir can be effectively channeled into the Moragahakanda reservoir, which in turn feeds a network of irrigation systems serving the North Central Province and other dry regions.Irrigation Support: The project significantly boosts the irrigation capacity of the region, providing water to approximately 81,400 hectares of agricultural land across Matale, Polonnaruwa, Anuradhapura, Trincomalee, and Kurunegala districts. This enhancement is vital for increasing agricultural productivity and ensuring food security in these areas.Hydropower Generation:The project includes provisions for generating 25 MW of hydropower, contributing approximately 114.5 GWh of energy annually to the national grid, which supports the country’s renewable energy goals.Drinking and Industrial Water Supply: In addition to irrigation, the canal system ensures the provision of 64 million cubic meters (MCM) of water annually for drinking and industrial purposes, benefiting numerous communities in the region.Impact and BenefitsEnhanced Agricultural Productivity: By ensuring a reliable water supply for irrigation, the Kaluganga-Moragahakanda Link Canal directly supports the livelihoods of thousands of farmers, enhancing agricultural yields and contributing to the region’s economic stability.Sustainable Water Resource Management:The canal is a critical component in the sustainable management of Sri Lanka’s water resources, particularly in the dry zones that are most vulnerable to water scarcity. Energy Contribution: The project’s hydropower component adds valuable renewable energy to the national grid, aligning with Sri Lanka’s energy diversification goals.Negative Aspect of the Project
The Moragahakanda Dam and the reservoir it created was funded by the China Development Bank, and the Kalu Ganga dam by the Saudi Fund for development, the Kuwait Fund for Arab Economic Development, and the OPEC Fund for International Development.
The Moragahakanda-Kalu Ganga Project was considered a “pioneer” project in conservation compared to similar initiatives. However, glaring negative impacts have surfaced and remain unresolved as a result of neglect by officials. The dam structures have destroyed elephant corridors, exacerbating human-elephant conflict in agricultural areas, especially in Matale — a city in the central province — where agitated elephants are ruining crops and properties built across inter-generational elephant migration routes.
“We have identified about 20 elephants that are causing the damage,” noted a wildlife officer of the Laggala Mountain area. The Wildlife Conservation Department (WCD) plans to chase these animals into the nearby Wasgamuwa National Park. The plan to round them up and corral them into this ‘protected space’ was due to begin in early March but the fuel shortage had scuppered it.
The elephant habitat has been substantially destroyed [as a result of these projects], says Manjula Amararathne, the WCD’s Director of Protected Area Management. It has been difficult to quantify the damage as the project covers other protected areas like the Elahera Sanctuary and Wasgamuwa National Park (part of which was acquired to establish ‘Laggala New Town’ for residents whose homes were submerged when the dam flooded the valley below).
The impacts of the Moragahakanda and Kalu Ganga dams on elephants are more far-reaching, even unprecedented, than predicted by the environmental impact assessments (EIAs). The Moragahakanda reservoir’s overflow is decimating the ‘Great Elephant Gathering of Minneriya’. Between 2016 and 2021, there was a 95% drop in elephants assembling every September in Minneriya National Park, says Sumith Pilapitiya an eminent wildlife researcher and the former WCD Director-General.

The irrigation waters of Moragahakanda reservoir were to be channeled through a 28km-long tunnel to Hurulu Wewa, onwards through the existing cascade system for agriculture in the North-Western and North-Central Provinces. If there had been proper planning, experts argue, the tunnel should have been ready before the reservoir was built, however when the dam was completed in 2018, the tunnels were still under construction. So the Minneriya reservoir would fill up during the dry season until the last tunnel was completed in 2021. This is bad for the elephants because when grasslands on the reservoir bed are submerged, elephants of the ‘Gathering’ no longer have their dry season fodder—something they were accustomed to for generations.
S. Ruwan from the Mahasen Jeep Safari Society works in the Minneriya National Park. The ‘Gathering’, he said, is one the biggest in Southeast Asia and attracts hordes of tourists, especially in August-September when around 300 elephants congregate. Since the completion of the Moragahakanda reservoir, this has plummeted to a gathering of around 20, he claimed.
“We’re losing our livelihoods because tourism has taken a hit repeatedly for a few years,” he said. “When the park’s main attraction is gone, people stop coming.”
Not only is tourism declining, but the human-elephant conflict in surrounding areas is also worse now.
Ruwan said the people want at least a quarter of the Minneriya Reservoir to be left empty so that the ‘Gathering’ could continue in whatever form possible.
Conservation experts assume that the accumulation of water in the Minneriya reservoir in the off-season is temporary. But Irrigation and Mahaweli Authority officials told the Sunday Times that it had been planned all along to send water from Moragahakanda to Kaudulla and Kantale through the Minneriya reservoir.
When questioned about the repercussions, Irrigation Authority officials said they knew nothing. “There is no elephant problem,” insisted engineer D. Abeysiriwardene, Director of Water Management. The Minneriya Tank, he also said, was for agriculture, “not for elephants”.
Abeysiriwardene reiterated that the impact on elephants was a “myth” and that the animals adjust to new situations. He said that conflict between the Forest Ministry and WCD had given rise to these falsehoods.
Environmental Impact Assessment (EIA) team members said, however, that the loss of this critical feeding site had been unpredicted and was now a “huge conservation problem” that experts were grappling to solve. It was a matter of “cart before the horse” said EIA team member Devaka Weerakoon. They had also thought it would be an issue only until the tunnels were constructed.
The Great Elephant Gathering of Minneriya losing its shine
The “Great Elephant Gathering” of Minneriya is a world famous tourist attraction named as one of the 10 greatest wildlife wonders of the world by Lonely Planet.
“There is no other such sight among the 13 Asian elephant range states and it has been a magnet for tourists, foreign and domestic, in their thousands,” Sumith Pilapitiya, Wildlife Researcher.
During the dry season from May to September, elephants gather on the dried-out lakebed of the Minneriya reservoir to eat fresh grass. During the peak in September, there are about 400 elephants.
The numbers of elephants reduce with the onset of the North-East monsoons in late October because when the water is released from the cascade reservoir system it fills the Minneriya reservoir and the lakebed with its grasses are submerged from December to April. But when water is emptied from the reservoir for agriculture in May, the grasslands re-emerge, bringing back the elephants.
This unique phenomenon has taken place in Minneriya for decades. It is a myth that elephants return to the reservoir during dry season for water. They come for the fresh grass which is higher in protein than mature grass. Water is an added bonus.
When food and water are plentiful, elephants, being social animals, congregate in large herds, giving rise to the ‘Great Elephant Gathering’ in August/September. The abundance of resources also triggers their natural biological behaviors.“Having plentiful resources stimulates the sexual hormones of elephants and it is common to observe females in estrus and males in musth,” Dr Pilapitiya said. The unusual sight of mating elephants and its associated male-male competition, musth posturing, and other interesting elephant behavioral characteristics can be observed at this time.
Since the construction of the Moragahakanda Reservoir in 2018, however, the Minneriya Reservoir has been full during the dry season due to unseasonal water releases that irrigation authorities claim are for agricultural reasons. Consequently, there has been a significant reduction in the elephant population.
“The project has a virtually irreversible adverse impact on the elephant gathering unless urgent remedial action is taken,” Dr Pilapitiya said.
There has been a reduction of about 95% in elephants gathering between 2017 and 2021. Apart from tourism revenue being lost, there appeared to be a greater than six-fold increase in the human-elephant conflict (HEC) in areas around Minneriya National Park. The rise in HEC was confirmed by locals and park safari drivers.

Environmentalists are livid
The dams should also have had a fish bypass or a fish ladder, aquatic ecologist Ivan Silva also said, because they block the currents that fish rely on to survive. River fish often die in still water. Dams, while creating habitats for new species, threaten existing endemic ones. The EIA had not placed enough importance on at-risk aquatic species.
“We will not know exactly how much we’ll lose since a comprehensive study of the fish was also not conducted,” Professor Silva pointed out, adding that eels in the Mahaweli River are nearly extinct because of the whole Mahaweli Development Project.
“The calculation of fish production is extremely erroneous,” he continued. Deep basins have less fish production because of lower oxygen. But project experts predicted Moragahakanda reservoir would have four times the production of Parakrama Samudraya, another nearby reservoir. “I assure you not even half of that will come out of Moragahakanda,” Silva said.
If there were fish, there would be fishermen. “How many boats can one see on these reservoirs?” he asked. Faulty predictions such as these throw cost-benefit analyses of the mega projects off balance. A fish ladder recommended by the EIA was shelved due to budget constraints — it was decided the conservation benefits did not outweigh the costs.
Another option, a fish bypass, proved impractical. So the EIA team chose translocation. Three thousand fish were shifted in bags and buckets to the upper regions of the Mahaweli River.
The Moragahakanda-Kalu Ganga is the first project of its kind in Sri Lanka with wildlife rescue plans. The inundation of massive areas places animals at risk of dying. The International Union for Conservation of Nature (IUCN) had given local authorities a two-stage program to secure wildlife in areas that would be inundated, a spokesman said, however, the second stage comprising of wildlife evacuation was not completed.
The EIA team, too, collaborated with IUCN in a plan to inundate the area gradually so the animals would travel uphill into islands that would form when the water came in, Prof Weerakoon said. Meticulous calculations were made. This plan was not followed, however.
“Unfortunately, when it comes to money, the environment is at the bottom of the priority list,” Weerakoon sighed.
The second stage was rushed because of leadership changes within the Mahaweli local authority, an anonymous source told the Sunday Times. Officials sat on blueprints for more than a year due to bureaucratic issues.
While certain that no species were wiped out, Prof Weerakoon warned that some may have been pushed to the brink of extinction. This could be an issue a decade down the line, he said, but cumulative impacts are rarely gauged as most projects are analyzed individually. Funding had become a problem, not because there was not enough, but because it was mismanaged.
The EIA team also calculated loss of habitat and forest cover, disturbances to movement patterns, threats to endemic species and the escalation of the human-elephant conflict. Several new protected areas were defined to make up for lost forest cover and although there-creation of an ecosystem similar to these forests is not possible, compensatory replanting had been done.
Mahaweli Authority officials insist all plans were followed to completion. A total of 350,000 trees on 9,500 acres were cut down for the two reservoirs, said D. B. Wijeratne, Project Director of the Moragahakanda-Kalu Ganga Development Project. Only 575,000 trees were replanted.
The purpose of the initiative was to irrigate the districts of Polonnaruwa, Trincomalee, Anuradhapura, Matale and Kurunegala. To date, Wijeratne said, all but Kurunegala gets irrigation water from the reservoirs. Cultivators who previously had water only for the Maha season from September to March, can now also farm during the Yala from May to August.
“A total of 100,000 hectares is cultivated annually thanks to the reservoirs and cropping intensity has increased by 1.8%,” Mr. Wijeratne said. These areas were greener, too. Locals in the forest were grateful for the projects as they saw roads being built.
“Back then we couldn’t imagine going to a hospital for an emergency because no vehicle could go on those roads, but now people can travel,” said one villager who sells roti and ‘beli-mal’ near Sera Ella, a tourist attraction in Laggala in the Matale District of Sri Lanka.
New buildings had also attracted visitors and this was good for business, another reflected. They could no longer grow certain crops because the climate had shifted significantly, but they had new revenue streams instead.
“Moragahakanda is the most destructive project of all Mahaweli Development initiatives,” maintained Jayantha Wijesinghe, Convener of the Rainforest Protectors. Damage to the pristine forest cover around the Knuckles range was immeasurable. Engineering failures that miscalculated the maximum flood level caused the authorities to cut several roads within ecologically sensitive areas.
To clear villages for catchment, residents were allowed to chop down trees on their properties for commercial use. “What’s the point of allocating a catchment area if all the trees are cut down?” Mr. Wijesinghe asked.
During the days of ancient kings, the central highlands were excluded from their complicated irrigation systems because of their value as a catchment for the whole country. “We’re cutting down the very forests that create rain and hoping more will come,” he warned. “When droughts extend and the reservoir dries up, we will be helpless.”
The people of Laggala — resettled or transplanted
Water was once plentiful in Heerati Oya, Nawa Laggala Pallegala. “Now access to good water has become so difficult,” says Ven Kambarawa Samitha Thera, Chief Incumbent of Sri Samakethiyaramaya.
He spoke from inside a mud hut erected on land allocated for a new temple. Seven years after resettlement, it is yet to be built.
People from the Mahaweli’s right banks were relocated from inundated areas like Rambukoluwa into newly established towns like Laggala New Town.
Water comes to town every three days in bowsers — mobile water tanks. They say it tastes like rust. “More of us have developed pressure, diabetes, and kidney issues,” says Samitha Thera. “Back then we had fresh mountain water.”
The government hands out food rations to resettled families — rice, dhal, dry fish and sugar. “These are people that worked hard, earned their own daily needs,” he observed.
The land that people were given as compensation were painfully disproportionate to the value of land people used to own. “Those who had about 16 acres got only half-an-acre from town,” he said. This was increasingly an issue as families grew. In the past, they had enough property to divide among children. Now, they did not. They had to cohabit with their parents or buy land from a more urbanized area. That was too costly for daily-wage earners now also hit by farming difficulties.
“There are no factories or big companies around here for people to work in,” Samitha Thera said.
Elephant attacks had worsened: “Even I sleep in fear.” This is because the town was on the border of Wasgamuwa National Park. Beyond the mountain, in the town of Handunugamuwa, a bear attacked three people, killing one and injuring the others.
On a positive note, there was easier access to education and more children attended school for longer. In the old village, the school was 9km away, accessible only on foot and had no electricity. Water was from the nearby river.
Now children were becoming more urbanized than when they lived in the forest. But this has increased alcohol abuse even among those as young as 16. Village kids unaccustomed to town life were giving into unhealthy habits.
“Our temple isn’t built yet because we don’t have enough money. As a result, I can’t even ask children to come in the evenings to teach them things,” he sighed. The compensation money wasn’t enough to put up the temple and people didn’t have enough to donate.
A majority of the resettled were farmers. The land they received, however, was unfit for paddy cultivation as irrigation channels were far away.
Mr. Rathnayake had sowed his land this season but he has low hopes as the agrochemicals ban had hit them in addition to other issues. Water was a challenge. They had thrived on water from the Kalu Ganga. Now, no more. Mainline pipes have been installed but do not function.
“In the village we didn’t pay for electricity. We used the water from the river,” said H M Sudharma, 22. Still, the resettlement gave them better roads and modern opportunities. She completed her A-levels in political science and media two years ago. She is targeting a job in a bag factory the government said it would set up there.
While the resettled struggle to adjust, business owners find their low spending power a challenge. This is worse than when cultivation fails. Nobody buys anything but their basic needs nowadays, said M G Ekanayake, an electronic goods seller in town. Resettlement was welcome but “badly planned”—the police station was in the middle of the town while the hospital was further away. And the town doesn’t have sufficient sanitation facilities.
The water bowser doesn’t cover the whole town, especially where roads are bad like his lane, he continued. “We’ve been living on water from a well we dug up for the past four months because the bowser hasn’t come.”
