Effect of hydropower on fishes of Uttarakhand
Authors

Abstract
River Bhagirathi in Garhwal region Uttarakhand of northern India is dammed at four locations (Maneri Bhali Phase I, Phase II, Tehri Hydroelectric Dam and Koteshwar Dam) for hydro power generation resulting in the fragmentation of riverine habitat. These Dams have affected seasonal cycles of floods, natural flow regime, and has caused increased sedimentation in impounded section of river. River dams also have profound impacts on ecosystems by changing habitats, hindering migration, life-history stages and population dynamics of the biota. Most affected species have been found Schizothorax, Glyptothorax, Pseudecheneis, Garra, Labeo, Crossocheilus, Noemacheilus, Barilius, Psilorhynchus, Clupisoma, Mastacembelus, and migratory Tor, spp., which are indigenous rheophilic species requiring distinct habitats to fulfil their life cycle stages. Populations of fast flowing riverine species have been collapsed or even disappeared from fragmented sections of the river system.
