Umiam Lake
Northeast India Region
Umiam Lake, also known locally as Bara Pani, is a man-made reservoir located about 15 kilometers north of Shillong in Meghalaya, India. Created in the early 1960s by damming the Umïam River, it serves as a vital water reservoir for hydroelectric power generation through the Umïam Dam, which was the first reservoir-storage hydroelectric project in Northeast India. The lake is fed by two rivers, Wah Umkhrah and Wah Umshyrpi, and spans a large catchment area of 225 square kilometers. The surrounding hills and serene waters make it a popular tourist destination, attracting visitors for boating, kayaking, water cycling, and other adventure sports. Despite its natural beauty and ecological importance, Umiam Lake faces environmental challenges such as pollution from upstream sewage and industrial waste and significant silting caused by deforestation and unplanned mining. Efforts to clean and preserve the lake include deploying solar-powered AI boats to remove floating refuse and oil. The lake also supports local communities by providing irrigation, fisheries, and drinking water downstream. Umiam Lake’s combination of scenic landscapes, recreational activities, and ecological significance makes it a unique and cherished spot in Meghalaya.

History
Umiam Lake was formed in the early 1960s when the Assam State Electricity Board constructed the Umïam Dam to harness hydroelectric power.
The dam’s Stage I powerhouse began commercial operation in 1965 with four turbine-generators.
This project marked the first reservoir-storage hydroelectric facility in Northeast India, following the earlier run-of-river Umtru Hydroelectric Project.
Prior to the dam’s construction, the valley was inhabited by Khasi communities, including the villages of Khwan and Umsaw, which were submerged, displacing around 200 families.
Subsequent development added three more stages downstream, expanding the hydroelectric capacity and shaping the region’s energy infrastructure.
