In India, the need for environmental flows has emerged from the hundreds of large dams being planned in the Himalayan rivers for hydro power generation. The cascades of dams planned across the Lohit, Dibang River in the Brahmaputra River , the Alaknanda and Bhagirathi River in the Ganga basin and the Teesta in Sikkim for example, would end up in the rivers flowing more through tunnels and pen stocks rather than the river channels. There have been some recommendations by various authorities (Courts, Tribunals, Expert Appraisal Committee of the Ministry of Environment and Forests (India)) on releasing e-flows from dams. However, these recommendations have never been backed by strong objectives about why certain e-flow releases are needed. See also Freshwater inflow Water scarcity References Rivers Aquatic ecology
