PONG DAM

The Pong Dam, also known as the Beas Dam, is an earth-fill embankment dam on the Beas River just upstream of Talwara in the state of Himachal Pradesh, India. The purpose of the dam is water storage for irrigation and hydroelectric power generation. As the second phase of the Beas Project, construction on the dam began in 1961 and was completed in 1974. At the time of its completion, the Pong Dam was the tallest of its type in India. The lake created by the dam, Maharana Pratap Sagar, became a renowned bird sanctuary.

The idea for a dam on the Beas at the Pong site was first proposed in 1926 and subsequent surveys of the Indus River and its tributaries were ordered by the Punjab Government in 1927. Interest in the dam declined after the report deemed the project difficult because of flood waters. In 1955, geological and hydrological studies were carried out on the Pong site and an embankment design was recommended. In 1959, extensive studies were carried out and recommended an embankment dam with a gravity section. A final design was issued and construction began in 1961 on the dam which was the second-phase of the Beas Project, the Pandoh Dam 140 km (87 mi) upstream being the first. It was completed in 1974 and the power station was later commissioned between 1978 and 1983. About 150,000 people were displaced by the dam's large reservoir under a poorly planned and executed relocation program.
