The Moragahakanda Dam, officially Kulasinghe Reservoir, is a large gravity dam, and the main component of the larger and more complex Moragahakanda — Kalu Ganga Project, across the Amban River at Elahera, in the Matale District of Sri Lanka. Construction began on 25 January 2007 and was completed in 2018. The maiden water release of the dam was in January 2017. Morgahakanda/Kaluganga project is the last of the Great Mahaveli project.

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. Both these sites would be located approximately 10 km (6.2 mi) apart.

The total development cost for both sites totals to approximately Rs. 48.145 billion (approximately US$370 million) and is being carried out by SMEC Holdings and Sinohydro.

A granite Buddha statue built opposite the Moragahakanda reservoir was unveiled on 23 July 2018.

Historical Significance:

Ancient Origins: The original Moragahakanda reservoir was first constructed by King Wasaba in 111 AD, highlighting the region’s long standing emphasis on irrigation and water management.

Modern Development: The concept of revitalizing and expanding the reservoir was incorporated into the Mahaweli Development Programme of 1968. Although initial plans were delayed due to various challenges, construction eventually commenced on January 25, 2007, and the project reached completion in 2018.

In honor of Deshabandu Dr. A.N.S. Kulasinghe, a distinguished Sri Lankan civil engineer renowned for his contributions to engineering projects nationwide, the reservoir was officially renamed the Kulasinghe Reservoir on July 23, 2018.
