MISSION The primary task of MASL has been and remains “ the improvement of human life in the Mahaweli impacted areas ”.... HISTORICAL BACKGROUND Shortly after independence, in the fifties, proposal for development of Sri Lanka (then Ceylon) were vigorously pursued. There was very little industry and hence development of agriculture was the main concern. Growing food for the expanding population became a priority. It was noticed by the political leaders, engineers and many others of that time that the largest river, the Mahaweli, was hardly being made use of and its waters emptied into the sea without benefiting the people. It was also noted that there were large areas of land in the Dry Zone which could be developed for growing of rice, if only water was available. In order to develop the water resources of the Mahaweli a joint study between the United States Operation Mission to Ceylon and the Irrigation Department resulted in a report titled “Mahaweli Ganga Basin Development Transbasin Diversion Scheme” published in April 1961. Thereafter, the Government obtained assistance from the UN and a UNDP / FAO mission along with the Irrigation Department prepared in 1968 a Master Plan for the Development of the Mahaweli Ganga for Irrigation and Hydro Power. The first phase of the project started with the construction of the Polgolla barrage across the Mahaweli and a tunnel to divert 57 cms of water to the Dry Zone. This was followed by the construction of the Bowatenna Dam and another tunnel to take water to the Kalawewa (down stream) areas. This work was done during the period 1969 to 1977. Then commenced the grand development works under the Mahaweli Accelerated Programme during the period 1978 to 1986 when the major dams such as Kothmale, Victoria, Randenigala, Rantambe and Maduru Oya were constructed with funds donated from several developed countries. At the same time development of large irrigation settlement in System H (Kalawewa), C (Dehiattakandiya) and B (Welikanda area) commenced and work was carried out successfully.

Godaliyadda Director General Irrigation Department Director REVIEW OF DIRECTOR GENERAL FOR THE YEAR 2010 The Mahaweli Authority of Sri Lanka (MASL) was established by the Parliament of Sri Lanka under Act no.23 of 1979. The year 2010 marks the completion of the 31 year of its existence. The functions of the Mahaweli Authority of Sri Lanka are set out in Section 12 of the MASL Act, and it is entrusted with the task of implementing the Mahaweli Ganga Development Scheme. The Mahaweli Authority of Sri Lanka is a service oriented organization which depends on funds allocated by the State annually. The Organization, in keeping with Good Governance practices, appointed a committee, namely the Audit & Management Committee, comprising three Members of the Board of Management and a representative of Auditor General by invitation. It is chaired by a Representative Member of Ministry of Finance & Planning. During the year, much progress has been made with regard to the on going development work in the foreign funded projects and promoting cultivation of cash crops in the irrigated areas. During the year, the MASL continued its emphasis on the development of investment activities in areas where irrigation and social infrastructure are already reached and operational facilities. The programmes for the settlement of farm families and provision of irrigation facilities as well as social infrastructure facilities were in progress in the year 2010. Furthermore, MASL has focused on the development of irrigated agriculture, minor food crops, livestock development, inland fisheries and industries in the Mahaweli systems to improve the socio-economic conditions of the rural population. MASL identified several inactive income and revenue generating sectors such as lease, rent, royalty from assets such as lands, buildings etc. Action has been taken during the year to improve these sectors to a higher level of productivity. The increased agricultural, livestock and fisheries production in the Mahaweli systems have greatly contributed in enhancing the national income. In conclusion, I would wish to express my sincere appreciation to my colleagues of the Board of Management and the staff of the MASL for the contributions made by them to achieve positive results in the year 2010. D.M.C.

  • A Case Study of the Kotmale Dam in Sri Lanka Jagath Manatungea* and Naruhiko Takesadab
    View metadata, citation and similar papers at core.ac.uk brought to you by CORE provided by Digital Repository, University of Moratuwa International Journal of Water Resources Development Vol. 29, No. 1, March 2013, 87–100 Long-term perceptions of project-affected persons: a case study of the Kotmale Dam in Sri Lanka Jagath Manatungea* and Naruhiko Takesadab aDepartment of Civil Engineering, University of Moratuwa, Sri Lanka; bFaculty of Humanity and Environment, Hosei University, Tokyo, Japan (Received 3 June 2012; final version received 11 June 2012) Many of the negative consequences of dam-related involuntary displacement of affected communities can be overcome by careful planning and by providing resettlers with adequate compensation. In this paper the resettlement scheme of the Kotmale Dam in Sri Lanka is revisited, focusing on resettlers’ positive perceptions. Displaced communities expressed satisfaction when income levels and stability were higher in addition to their having access to land ownership titles, good irrigation infrastructure, water, and more opportunities for their children. However, harsh climate conditions, increased incidence of diseases and human–wildlife conflicts caused much discomfort among resettlers. Diversification away from paddy farming to other agricultural activities and providing legal land titles would have allowed them to gain more from resettlement compensation. Keywords: dam construction; involuntary displacement; livelihood rebuilding; resettlement compensation Introduction Over the decades, there has been growing concern about the negative consequences of the involuntary displacement of rural communities for large-scale infrastructure development (De Wet, 2006; Robinson, 2003). The construction of dams is the most often cited example of development projects that cause forced displacement of communities (McCully, 2001).

  • 1 SRI LANKA: Integrated Watershed & Water Resources Management
    SRI LANKA: Integrated Watershed & Water Resources Management Project Executive Summary of Safeguard Documents (A) ENVIRONMENT AND SOCIAL MANAGEMENT FRAMEWORK (ESMF) Background: The Global Climate Risk Index 2019 ranks Sri Lanka as the second among the most affected countries of the World by climate change. The impacts of climate change are already starting to show with severe and long duration droughts followed by severe flooding and landslides occurring almost every year in several parts of the country. The island’s major rivers originate from the mountains in the central region and radiate out to the lowlands to distribute water across the country; making the central region the main watershed of the country. Over the years, forest cover in the upper watersheds have been extensively modified, degraded and fragmented. The natural montane wetlands and marshlands have been converted to agricultural lands and other anthropogenic land uses. Lowered capacity for water infiltration and retention in the upper watershed areas has contributed to increasingly variable and uncertain water availability affecting agriculture and industrial growth, community and individual livelihoods, and even lives. Studies show that these trends are likely to exacerbate, and the wetter areas of the country would eventually become wetter and the drier areas drier. Unplanned settlements, industrial projects, and maladaptive agricultural practices are creating additional water stresses. It is estimated that approximately 80% of the river basins have greatly reduced their water quality and quantity due to these unplanned activities. Sri Lanka’s water resources are critically important to sustain the country’s socio-ecological integrity and development goals. As such, the Government of Sri Lanka (GoSL) has initiated many watershed and water resources management programs focusing on various geographical areas of the country to address these challenges.

Udayakumar Abstract The main focus of this thesis work is to perform a preliminary evaluation for the introduction of a pumped energy storage system to an existing hydropower plant located on the Randenigala water reservoir in Sri Lanka. The selected power plant is located in an area where farming is done extensively, therefore electrical power generation and release of water for downstream irrigation purposes is to be properly coordinated with relevant authorities. The solution to this situation is to introduce a wind powered pumped energy storage power plant to the Mahaweli hydro cascade for the purpose of saving peak power for around half an hour. A feasibility study was carried out on the utilization of wind energy and excess power to drive the motors of the pumped storage system. Three versions with different numbers of pump motors and wind turbines have been considered to meet the half hour peak demand of the energy storage system. The optimum number of turbines and motor capacities and their number and brand have been selected with view of both energy and water management system.

  • Introduction
    A Place for Dams in The 21st Century? INTRODUCTION “remarkable feat in the history of mankind to reshape and exploit the resources” was how AChinese President Jiang Zemin described the closure of the Yangtze River in November 1997.1 Similar statements have been made by every major politician in developed and developing countries in the past 60 years. Scientists, economists, artists and naturalists have also been ‘impressed and inspired’ by the human endeavour to ‘exploit’ rivers to produce food and energy.2 Differing Viewpoints Dam construction has raised concerns and sentiments in many countries (see, for example, comments on the Three Gorges Dam, Box 1). The greatest challenge now is to start a genuine and fruitful debate on finding the most suitable ways and means to meet energy needs, water requirements and food production, while conserving biodiversity. Dams have to be seen as a means to an end, rather than an end in themselves. The conservation of natural resources and an improvement in the quality of human life should be at the heart of this issue. The issues and debates over large dams have not changed significantly since the 1940s and 1950s. What has changed is that dam construction has shifted geographically from developed to developing countries. Several developing countries that are now building similar, or even larger, dams than those in the west emphasise the same arguments of the benefits of dams. WWF, in principle, does not favour the construction of any new large dam as they all lead to environmental damage. In the past, WWF has expressed concern over many proposed dams – The large dam Gabcikovo and Hydrovia, for example.
