The Inginimitiya Dam (Sinhalese: ඉඟිණිමිටිය ජලාශය) is an embankment dam built across the Mi Oya, at Inginimitiya, Sri Lanka. Measuring 4,880 m (16,010 ft) wide and 18 m (59 ft) tall, the dam creates the popular Inginimitiya Reservoir, which is primarily used for irrigation purposes, among other reasons.



The reservoir facilitates supply of water to 6539 acres land for agriculture, including new land area of about 4600 acres. [1] [2] The idea for making reservoir in Inginimitiya has been proposed for the first time in Rajya manthrana sabha before 75 years ago in 1930s. But the construction of reservoir was commenced on 14 March 1981 and declared opened on 25 March 1985 by then Sri Lanka President J. R. Jayawardene. Overall project scheme was funded as loan aids by Japan and it is Yen 1800 Millions. Apart this Sri Lanka government has been received Rupees 89,000,000 as local funds. [3]

Kaleshwaram Lift Irrigation Project dam in Kaleshwaram, Bhupalpally, Telangana, India

The Kaleshwaram Lift Irrigation Project or KLIP is a multi-purpose irrigation project on the Godavari River in Kaleshwaram, Bhoopalpally, Telangana, India. Currently the world's largest multi-stage lift irrigation project, its farthest upstream influence is at the confluence of the Pranhita and Godavari rivers. The Pranahita River is itself a confluence of various smaller tributaries including the Wardha, Painganga, and Wainganga rivers which combine to form the seventh-largest drainage basin on the subcontinent, with an estimated annual discharge of more than 6,427,900 acre feet or 280 TMC. It remains untapped as its course is principally through dense forests and other ecologically sensitive zones such as wildlife sanctuaries.
