\/><\/p>\r\n<h2><span style=\"font-weight: 400\">Major Dams in India Significance<\/span><\/h2>\r\n<p><span style=\"font-weight: 400\">Dams are critical to India's water management and development efforts. They offer significant benefits, including:<\/span><\/p>\r\n<ul>\r\n\t<li><b>Renewable Energy Source:<\/b> <span style=\"font-weight: 400\">Many dams have turbines installed to generate electricity from the regulated water flow. These hydroelectric dams are a vital source of renewable energy for the country.<\/span>\r\n<ul>\r\n\t<li><span style=\"font-weight: 400\">For instance, in 2026, a hydropower capacity of about <\/span><b>52,064 MW <\/b><span style=\"font-weight: 400\">(megawatts) accounted for roughly <\/span><b>11%<\/b><span style=\"font-weight: 400\"> of power generation capacity in India.<\/span><\/li>\r\n<\/ul>\r\n<\/li>\r\n\t<li><b>Irrigation: <\/b><span style=\"font-weight: 400\">Large dams have played a crucial role in improving irrigation facilities, increasing the area under cultivation, and boosting agricultural productivity, contributing to India's self-sufficiency in food grain production.<\/span><\/li>\r\n\t<li><b>Flood control and water supply: <\/b><span style=\"font-weight: 400\">During heavy rainfall, dams can prevent floods by controlling water release. Conversely, they maintain a reliable water supply during dry conditions.<\/span><\/li>\r\n\t<li><b>Efficient land use:<\/b><span style=\"font-weight: 400\"> While large dams submerge land, they do so relatively sparingly compared to alternative small dams.
