The MLBCRP will raise the Minipe anicut / headworks weir by 3.5 m to increase upstream storage and rehabilitate the 74 km Minipe Left Bank Canal to improve conveyance and reliability of service to existing farmers. Storage behind the existing anicut is insufficient to ensure that water is available for the left and right bank canals between releases from Rantambe hydroelectric facility, which occur twice a day to respond to peak demands for electricity.
The office of the Project Implementation Unit (PIU) has been opened in the premises of tehh Department of Irrigation in Hasalaka. The cost of the MLBCRP is estimated at some LKR 2600 million.
The trans-basin canal from Minipe diversion carried water from Mahaweli Ganga to Amban Ganga. King Dasankeliya (459 AD) constructed this canal, which irrigated lands on the left bank of the Mahaweli Ganga. ‘Yakinna-bendi-Portawa’ anicut in Minipe was, according to legend, constructed by a she-devil under royal favour and is one of the ancient irrigation works, which came into the limelight in the 1960s during the excavations of the Archaeological Commissioner, Dr. Senarat Paranavithana. (Daily news)
This gigantic work, which inspires wonder among modern engineers, consists of a scheme that diverts the river at a bend where a large body of water enters the narrow canal formed by an island close to the bank, partially closed by two rocks, and intercepts the water on its return to the main stream. These rocks, when joined by masonry construction, became a dam raising the waters in the natural channel to a great height. Sir Henry Ward Basing in his observation on the legend describes this canal as having been capable of use for irrigation as well as for navigation. The length of this canal is 50 miles and it merges with the Amban Ganga below Angemedilla anicut. It is important to note that this canal followed an alignment that minimized deep cutting.

An Initial Environmental Examination was also carried out for the MLBCRP and approved by the Central Environmental Authority. Possible project impacts on the environment and water availability in downstream areas following the raising of the Minipe anicut were studied during the design stage of the project. It is planned to maintain the regular water flow along the Mahaweli River toward the downstream throughout the year to ensure environmental and downstream users’ needs are satisfied. Following the approval of Forest Department and Central Environment Authority, the project will execute reforestation programs to enrich the forest cover in the project area. The Project has taken the necessary steps to feed the mini tank located in Wasgamuwa forest reserve to meet the drinking water requirement of wild animals during dry seasons. Rehabilitation and construction will be carried out in compliance with the Environmental Management plan which is prepared as per the CEA approved IEE – approval conditions under the National Environmental Low and Environment Safeguard Policy (2009) of ADB. Financial allocation of around 7% is allocated for environmental mitigations and specialized manpower with required procedural provisions are in place to ensure proper environment management of the project.
